Objective: The objective is to study the epidemiologic profile of unnatural death among females using autopsy data. Design: This is a 14-year descriptive retrospective study of all female unnatural death victims within Warri and its neighboring communities subjected to medicolegal autopsy. Materials and Methods: Information on age as well as manner and method of death were extracted from the autopsy report of the cases and subsequently analyzed using Microsoft Office Excel 2007. Results: Ninety-six females were examined in this study, representing 9.9% of the 975 medicolegal performed and 11.4% of the 805 unnatural deaths encountered during the study period. The age range is 1–70 years and the mean age is 29.82 years. These cases represent a mean annual incidence of about seven cases. The peak incidence of unnatural death occurred in the third decade (27.1%), followed by the fourth (19.8%) and fifth (15.6%) decades, respectively. The peak incidence for homicide and accidental deaths is in the third and fourth decades, respectively. Firearm-related death is the leading method of homicide accounting for 24 (53.3%) of the 45 homicide deaths. The use of blunt and sharp weapons each accounts for 10 (22.2%) of the cases. Road traffic accident (RTA) accounts for 28 cases, representing 59.6% of accidental deaths and 29.1% of unnatural deaths. Burns and drowning are the second and third leading causes of accidental death accounting for 11 (23.4%) and 3 (6.4%) of the accidental deaths. Four cases of suicide were encountered with three deaths as a result of ingestion of chemical poisons, while the fourth case was by hanging using rope. Conclusion: The study showed that unnatural deaths in women are mainly accidental, homicidal, and suicidal representing 49.0%, 46.0%, and 4.2% of the cases respectively. RTA, burns, drowning, and poisoning (in descending order) are the major causes of accidental deaths. Firearm, sharp, and blunt injuries (in descending order) are the major methods of executing homicides. The peak age for unnatural death is in the third decade with 75% of the death clustering within the 2nd–4th decade. Education, accident consciousness, parental supervision, and implementation of appropriate policy measures are paramount to reducing such death.

Road traffic accident (RTA) accounts for 28 cases, representing 59.6% of accidental deaths and 29.1% of unnatural deaths. Burns and drowning are the second and third leading causes of accidental death accounting for 11 (23.4%) and 3 (6.4%) of the accidental deaths. Four cases of suicide were encountered with three deaths as a result of ingestion of chemical poisons, while the fourth case was by hanging using rope. Conclusion: The study showed that unnatural deaths in women are mainly accidental, homicidal, and suicidal representing 49.0%, 46.0%, and 4.2% of the cases respectively. RTA, burns, drowning, and poisoning (in descending order) are the major causes of accidental deaths. Firearm, sharp, and blunt injuries (in descending order) are the major methods of executing homicides. The peak age for unnatural death is in the third decade with 75% of the death clustering within the 2nd–4th decade. Education, accident consciousness, parental supervision, and implementation of appropriate policy measures are paramount to reducing such death.

It does interfere with patient monitoring and markedly increases the metabolic rate. Traditionally, shivering has been aborted with intravenous pethidine. Recently, the addition of pethidine to the local anaesthetic intrathecal injectate has been shown to reduce the incidence and severity of post spinal shivering without modifying the characteristics of the block but may increase opioid related side effects. RATIONALE AND HYPOTHESIS: The determinations of the dose of intrathecal opioids that will prevent shivering without showing opioid related side effects will improve patient’s safety. The efficacy of 0.1mg/kg of pethidine added to intrathecal bupivacaine injectate in ameliorating post spinal shivering was evaluated. STUDY DESIGN: This is a prospective randomized double blind placebo controlled trial. Approval was sought and received from UBTH Research and Ethics Committee. A prehoc power analysis indicated the recruitment of 42 patients in each group to detect a 30% reduction in the incidence of shivering (α = 0.05, β = 0.2). A 5% attrition level was assumed and eighty-eight subjects were drawn from ASA 1 or 2 patients scheduled for elective caesarean delivery in UBTH, Benin City. Exclusion criteria included height <152cm or >183cm, weight >110kg, use of opioid analgesics in the past 24hours and presence of intercurrent illness. Following informed consent, they were randomized to receive a standardized spinal anaesthesia using 2.2mls of 0.5% bupivacaine to which was added either 0.1mg/kg of pethidine (Group P) or an equivalent volume of normal saline (Group S). The presence of shivering and its severity, core temperature and patients cold score, highest sensory dermatomal level of block and opioid related side effects and perioperative complications were recorded. The data obtained were analysed using Statistical Programme for Social Sciences (SPSS) 16.0 software (Chicago Illinois, USA). Demographic data was compared using Fisher’s exact test. Proportions of women that shivered was compared using Fisher’s exact test while the maximal intensity of shivering recorded for each patient is studied with Mann Whitney U-test. The relationship between minimal temperature and shivering, and cold scores and shivering were determined with Spearman Correlation coefficient. The level of significance was set at a probability of 5%. All tests were two tailed. RESULTS: Eigthy-eight women were randomized to the pethidine group and saline group. There was no significant difference in the sociodemographic characteristics and the intraoperative clinical variables between the groups. There was a significant reduction in the incidence of shivering in the pethidine group [33% versus 71%; (p < 0.0009) Fisher’s exact test], the maximal intensity recorded for each patient [(p < 0.004) Mann Whitney U test]. There was no significant difference in the incidence of opioid related side effects and perioperative complications (p > 0.49). CONCLUSION: This study showed that addition of 0.1mg/kg of pethidine to the intrathecal bupivacaine reduces the incidence and severity of shivering significantly with a minimal side effect profile. SIGNIFIGANCE: This study provided data that suggest 0.1mg/kg of pethidine added to the local anaesthetic spinal injectate significantly reduces the incidence and severity of post spinal shivering. This is important as patients will thus be spared the obnoxious effects of shivering and opioid related side effects.

The calculated amount of diesel fuel energy consumed was about 18.4GWh/year and 29.5GWh/year for Mill A and B respectively, which is a total of 47.9GWh/year. However, the energy requirement of the process machines and consumption capacities for Mills A and B was a total of 14.1GWh/year which is far lesser than the energy generated from the diesel fuel used. Hence, a lot of energy is being wasted in the flour production plants. |

This study, therefore, investigated its antidepressant potentials, using cold maceration method, and determined the probable neurobehavioural mechanism of its antidepressant-like effect. Methodology: The antidepressant-like effect of the extract was evaluated in tail suspension test, at graded doses in mice. Subsequently, the probable neurobehavioural mechanism of the antidepressant-like effect of the extract was investigated by intraperitoneal pretreatment with adrenergic, serotonergic, dopaminergic, and muscarinic cholinergic receptor antagonists; GABA agonist; nitric oxide precursor and inhibitors; and using a putative neuromodulator at NMDA receptors prior to the extract administration. Results and discussion: The extract at all the doses used, significantly (p<0.05) and dose-dependently decreased the immobility time in tail suspension test without significant (p>0.05) alteration on locomotor behaviour in mice. However, the anti-immobility potential of the extract was significantly (p<0.05) reversed by prazosin, yohimbine, sulpiride, methylene blue, L-arginine and baclofen, suggesting the involvement of adrenergic, dopaminergic, GABAerargic and nitergic pathways.

Methodology: Amnesia was induced by intraperitoneal injection of scopolamine (0.4mg/kg) in Morris Water Maze; scopolamine (1mg/kg) on Y-maze test; scopolamine (0.4mg/kg) and diazepam (1mg/kg) on elevated plus maze. The effect of the extract on learning and memory of young and aged mice was also investigated on the elevated plus maze. The probable mechanism of cognitive enhancing effects of the extract was investigated using acetylcholinesterase enzyme and nitric oxide assays. Results: The extract significantly (p<0.05) attenuated amnesia induced by scopolamine in Morris water maze; reversed amnesia induced by scopolamine and diazepam on elevated plus maze; increased spontaneous alternation behaviour without modifying locomotor activities on Y-maze test; inhibited natural age-induced learning and memory impairment of aged mice while the learning and memory of young mice were significantly (p<0.05) enhanced on elevated plus maze.

Therefore, the consumption of these contaminated fish and shellfish by the people of Koko portends risks of the health of the public. The industries operating in this community should adopt more sustainable and eco-innovative management options in order to attenuate potential ecological and human health risk of metal pollution. |

Place and Duration of Study: Department of Pharmacology, Faculty of Pharmacy, Obafemi Awolowo University, Ile-Ife, Osun State, Nigeria, between January 2014 and February 2015. Methodology: The anticonvulsant effect of ethanol leaf extract (EME), n-hexane (HF), ethyl acetate (EAF), n-butanol (BF) and aqueous (AF) fractions of the extract was evaluated using picrotoxin-, pentylenetetrazole-, and strychnine-induced convulsion models. The neural mechanism of anticonvulsant effect of the most active fraction (AF) was also investigated using flumazenil (3 mg/kg, i.p.), cyproheptadine (4 mg/kg, i.p.) and L-NG-Nitroarginine (10 mg/kg, i.p.) in picrotoxin-induced convulsion model. Results: EME and AF significantly (P < .05) delayed the onset of clonic and tonic convulsions and prolonged death latency with varying degrees of protection in picrotoxin-, and pentylenetetrazole-induced convulsion models. EME, EAF and AF significantly (P < .05) pronlonged the onset of clonic convulsion in strychnine-induced convulsion in mice. Flumazenil, cyproheptadine and L-NG-Nitroarginine abolished the anticonvulsant effect of AF suggesting the involvement of GABAergic, serotonergic and nitergic pathways. Conclusion: This study concludes that Milicia excelsa leaf contains biologically active anticonvulsant principles, thus lending pharmacological credence to the suggested traditional use. Further study may be undertaken to isolate and elucidate the chemical structure of the biologically active ingredient(s) responsible for the observed anticonvulsant effect.

Methods: In the present study, we examined the effects of caffeine (2.5, 5 and 10 mg/kg) on alcohol consumption in Wistar rats with or without periods of deprivation in an unlimited-access, two-bottle, free choice drinking procedure after a stable baseline alcohol consumption was established. Conditioned place preference (CPP) was established by intraperitoneal injections of alcohol (2 g/kg) in a 12-day conditioning schedule in mice. The effect of caffeine (3 mg/kg) on CPP expression was determined by a final post-conditioning test following 12 conditioning sessions with alcohol. The effect of caffeine (3 mg/kg) on the reinstatement of alcohol-induced CPP was determined in a final post-conditioning test following 12 conditioning sessions with alcohol and the extinction of alcoholinduced CPP. Results: Alcohol deprivation for 3 days did not result in alcohol deprivation effect (ADE). While caffeine (10 mg/kg) caused a significant (p < 0.05) reduction in alcohol consumption compared with the baseline following a period of alcohol deprivation, it did not cause a change in alcohol consumption compared with the baseline in the study without alcohol deprivation phase. Caffeine significantly (p < 0.05) reduced the expression of alcohol-induced CPP compared to saline and blocked the reinstatement of alcohol-induced CPP following the injection of a priming dose (0.4 g/kg) of alcohol Conclusions: Given that caffeine is an adenosine receptor antagonist, our findings suggest a role for adenosine receptors in the alcohol reward and alcohol-seeking behaviour.

EME and all the fractions significantly (P < 0.05) inhibited the hypermotility induced by ketamine while the number of ataxia was significantly (P < 0.05) reduced by EME, EAF and AF in ketamine-induced hyperlocomotion, with AF producing a stronger ataxia reducing effect compared to haloperidol, a reference antipsychotic drug. EME and EAF showed consistent antipsychotic activities in all the models used. Conclusion: This study concludes that EME and all its fractions may be safe and contain antipsychotic principles, thus, providing scientific evidence for the suggested ethnomedicinal use of the leaf in treating insanity in traditional medicine.

Study Design: This study used experimental mice models predictive of human psychosis. Place and Duration of Study: Department of Pharmacology, Faculty of Pharmacy, Obafemi Awolowo University, Ile-Ife, Osun State, Nigeria, between January 2014 to February 2015. Methodology: The antipsychotic effect was assessed using swim-induced grooming; apomorphine-induced climbing and ketamine-induced hyperlocomotion behaviours in mice. Results: The results showed that the LD50 of the ethanol extract and its various fractions were greater than 5000 mg/kg. EME and all its fractions significantly (P < 0.05) decreased the number of grooming while the duration of grooming was significantly (P < 0.05) reduced by EME, EAF and AF in swim-induced grooming.

This study evaluated the analgesic and antioxidant activities of aqueous extract of HU stem bark and the possible mechanism(s) of action. Methods The antinociceptive effect of HU was evaluated using acetic acid mouse writhing, tail flick, hot plate and formalin-induced paw licking models. To establish the possible mechanism(s) of action of HU, separate group of animals were pretreated with naloxone (1 mg/kg, i.p.), atropine (1 mg/kg, i.p.), haloperidol (0.1 mg/kg, i.p.), ondansetron (1 mg/kg, i.p.) and phenoxybenzamine (0.1 mg/kg, i.p.), 15 min before HU. The in vivo and in vitro antioxidant potential was evaluated using established methods. Results The extract at 150 and 300 mg/kg, significantly (p<0.05) reduced the number of writhes and paw licking times and increased pain threshold in writhing assay, paw licking and hotplate tests respectively. Pretreatment of animals with ondansetron, naloxone and haloperidol, significantly (p<0.05 and p<0.01) attenuated the analgesic activity of HU. The extract demonstrated significant (p<0.05) radical scavenging activity (IC50 0.39 µg/mL), with high phenol content and reducing property. The total phenol content was 124.19 per gram of gallic acid. In vivo antioxidant assay showed significant (p<0.05) increase in catalase and superoxide levels.

The isolated compound, jatrophone was evaluated for its antiprotozoal activity against Plasmodium falciparum strains [D6 (chloroquine sensitive) and W2 (chloroquine-resistant)], Leishmania donovani and Trypanosoma brucei. The antimicrobial activity was evaluated against type culture of selected fungi and bacteria. Analgesic activity was investigated using the acetic acidinduced writhing and hot plate model in mice. The cytotoxicity was assessed against VERO cell line (monkey kidney fibroblast) using neural red uptake method. Results: Jatrophone showed significant antiplasmodial and antileishmanial activities with IC50 of 0.55, 0.52 and < 0.4 µg/mL for P. falciparum (D6 strain), P. falciparum (W2 strain) and L. donovani respectively. Compound 1 was highly cytotoxic to VERO cell line with IC 50 of 0.43 µg/mL. Jatrophone demonstrated significant analgesic effect with a percentage reduction in acetic acid-induced writhes of 54.03% and 66.35% at 5 and 10 mg/kg respectively. No significant antimicrobial activity was observed against the test organisms. Conclusion: The present study has shown that jatrophone possess antimalarial, antileishmanial, and analgesic activities.

Aripiprazole has been reported to show good efficacy with low side effect profiles in Caucasians. No studies have been conducted to assess its effectiveness and tolerability in a Nigerian population hence the need for this study. Methods: A post marketing surveillance was conducted involving patients with first episode psychosis presenting to a regional tertiary psychiatric facility in Nigeria. Participants were titrated through a dose range of 10-30 mg of aripiprazole depending on response or tolerability and followed up over a 12 week period. Assessments at baseline, at 2, 6, and 12-weeks post recruitment were done to rate severity of psychopathology (CGI, PANSS), side effects (MSAS), functioning (GAF), and medication adherence (MARS). Results: Of fifty patients completing the study (49.5% drop-out rate), we observed significant improvements at 12 weeks compared to baseline in symptom remission (p<0.001), clinician rating of improvement (p<0.01), and psychosocial functioning (p<0.001). There were no significant changes compared to baseline as regards medication adherence, extra pyramidal side effects (p=0.23), fasting blood sugar (p=0.67) and fasting cholesterol (p=0.57) Conclusion: Aripiprazole may be effective and tolerable among individuals with first episode non-affective psychoses presenting at a tertiary psychiatric facility in Nigeria. Keywords: Aripiprazole, first episode psychoses, tolerability, efficacy, Nigeria}, keywords = {}, pubstate = {published}, tppubtype = {article} } Abstract Background: Individuals with first episode psychoses often discontinue pharmacotherapy due to poor symptom remission and/or intolerable side effects. Aripiprazole has been reported to show good efficacy with low side effect profiles in Caucasians. No studies have been conducted to assess its effectiveness and tolerability in a Nigerian population hence the need for this study. Methods: A post marketing surveillance was conducted involving patients with first episode psychosis presenting to a regional tertiary psychiatric facility in Nigeria. Participants were titrated through a dose range of 10-30 mg of aripiprazole depending on response or tolerability and followed up over a 12 week period. Assessments at baseline, at 2, 6, and 12-weeks post recruitment were done to rate severity of psychopathology (CGI, PANSS), side effects (MSAS), functioning (GAF), and medication adherence (MARS). Results: Of fifty patients completing the study (49.5% drop-out rate), we observed significant improvements at 12 weeks compared to baseline in symptom remission (p<0.001), clinician rating of improvement (p<0.01), and psychosocial functioning (p<0.001).

A total of 534 subjects of 18–25 years of age participated. Direct sensing and photographs methods were used to determine fingerprint and facial features, respectively. Fisher’s Exact test was used to test for association between variables. Results. It was observed that in both males and females there was no (0%) occurrence of classical canon of facial proportion. There was also no association between sex and facial proportions. A significant association was found in between thumbprint patterns and vertical class III neoclassical facial proportion only when the frequency of both left and right thumbprint patterns was considered a single entity. There is no significant association between the thumbprint patterns of the right and left thumbs with vertical horizontal facial proportions in male and female participants.

Open and close ended questionnaires made up of 40 items on demographic, knowledge of LD, types of LD used by participants, frequency of use, quantity of LD used and reasons for the use of lifestyle drugs was administered to 400 participants. Results: Out of 400 students that filled the selfadministered questionnaire 210 (52.50%) were males and majority were single (91.25%) and between 18 - 24 years. High proportion of respondents (45.2%) was not aware of LD drugs even if they had used them before. Caffeine was the drug commonly used by respondents with 85% admitting taking it while65.3% used nutritional supplements. Other LD with high frequency of usage were topical skin lightening drugs (45%), alcohol (41.5%) and narcotics (31%).

All the strains were susceptible to Vancomycin, Linezolid and Rifampicin while they were all resistant to Penicillin, Fusidic acid, and Trimethoprim. Brevibacterium epidermidis were generally resistant to Erythromycin and Clindamycin while B. iodinum and B. oceani were susceptible. Conclusion - 16S rRNA identification is the only method that could correctly identified Brevibacterium sp to the species level in this study. High susceptibility was shown by all tested strains to Vancomycin, Linezolid and Rifampicin |

Enterobacteriaceae are ubiquitously present in nature and can be found in the intestinal tract of humans and animals as commensal flora. Multidrug-resistant Enterobacteriaceae are increasingly reported and are a threat to public health implicating a need for accurate identification of the isolates to species level. In developing countries, identification of bacteria basically depends on conventional methods: culture and phenotypic methods that hamper the accurate identification of bacteria. In this study, matrix-assisted desorption ionization-time of flight mass spectrometry (MALDITOF MS) technique was compared to conventional identification techniques. Materials and Methods. In total, 147 Enterobacteriaceae isolates were collected from March to May 2015 from three medical microbiology laboratories of hospitals in Edo state, Nigeria, after being tested according to the individual laboratories standard operating procedures. All isolates were stored at 20 C until tested centrally by MALDI-TOF MS. Results. One hundred and forty five (98.6%) isolates had a MALDI Biotyper best score > or =2.0, indicating a secure genus and probable species identification; and 2(1.36%) isolates had a best score <2.0 indicating probable genus identification.

However, blood and blood component transfusions are associated with some adverse transfusion reactions. Some of these reactions can lead to loss of patients’ lives and hence defeating the essence of blood usage in saving lives. Objectives: This study aims to establish those factors promoting and increasing the susceptibility of patients for adverse transfusion reactions. Methodology: Two-year records (July 2014-June 2016) of our patients reported to have blood transfusion reactions were retrieved, data collated and analysed using IBM SPSS version 22 software. Results: Forty-six cases out of 5,342 transfusions were reported giving a prevalence of 0.86%. The youngest case was two years while the oldest was 70 years. The mean age was 38.69±14.95 years. Thirty five (76.1%) of the cases were females while 11(23.9%) were males. Chills/rigors (63%) and fever/pyrexia (58.7%) were the major presenting symptoms. Fourteen of the cases (30.4%) complained of itching/urticaria while 19.6% presented with nausea/vomiting. The clinical signs were hypotension (6.5%), tachypnea (4.3%) and tachycardia (2.2%). The adverse transfusion reactions were mainly associated with whole blood (93.5%) and 58.7% of the reactions occurred at night. Anaemia was the major indication for the transfusions (80.4%).

The 13 arguments were ranked in terms of strength, from strongest to weakest. The results of the study show that taxational and fiscal factors, economic factors and administrative factors, among other factors are statistically significant for individuals’ tax-evasion behavior. These findings may be useful to policy makers and researchers.

This may lead to higher tax compliance in the long run. }, keywords = {}, pubstate = {published}, tppubtype = {article} } ABSTRACT The objective of this paper is to empirically investigate the determinants of informal sector tax evasion in Sokoto Metropolis. A survey was conducted using a seven-point Likert scale that included 13 arguments and distributed 317 questionnaires to potential tax payers within Sokoto Metropolis, 300 questionnaires were returned and analyzed using regression analysis. The 13 arguments were ranked in terms of strength, from strongest to weakest. The results of the study show that taxational and fiscal factors, economic factors and administrative factors, among other factors are statistically significant for individuals’ tax-evasion behavior. These findings may be useful to policy makers and researchers. Specifically, tax authorities should design policies to help increase the income level of taxpayers rather than increasing administrative measures toward taxpayers. This may lead to higher tax compliance in the long run. |

(Onuorah and Appah, 2012) The incidence of fraud continues to increase across private and public sector organizations and across nations. Fraud is a universal problem as no nations is resistant, although developing countries and their various states suffer the most pain. Today; modern organized financial crimes have appeared. Financial crimes such as employee theft, payroll frauds, fraudulent billing systems, management theft, corporate frauds, insurance fraud, embezzlement, bribery, bankruptcy, security fraud (EFCC, 2004), among others, have taken the centre stage in the scheme of things; and on the scale of private, public and governmental preference. Financial crimes today have grown wild, and the emergence of computer software coupled with the advent of internet facilities has compounded the problem of financial crimes. Besides, the detection or minimization of these crimes are made more difficult and committing these crimes much easier. (Izedonmi, and Ibadin, 2012). All these, no doubt, remain outside the ambit of the statutory auditor to report on except he is placed on inquiry. The statutory auditor is not primarily bound to detect fraud and errors. His responsibility is defined by Sec. 359 (CAMA, 2004) and the relevant auditing standards. (Uwojori and Asaolu, 2009) added that quite unfortunately, is the inability of the statutory auditor constrained by the relevant statutes and standards, to deal with financial crimes.

It has become imperative for accountants at all levels to have the requisite skills and knowledge for identifying, discovering as well as preserving the evidence of all forms of irregularities and fraud. Therefore, fraud requires more sophisticated approach from preventative to detection. One of the modern approaches that can be used from the prevention to detection is called forensic accounting. Forensic accounting is a rapidly growing field of accounting that describes the engagement that results from actual or anticipated dispute or litigations. (Okoye and Gbegi, 2013) concur that “Forensic” means “suitable for use in a court of law”, and it is to that standard that Forensic Accountants generally work.

Although, forensic accounting has been in existence for several decades, it has evolved over time to include several types of financial information scrutiny. Forensic accounting can, therefore, be seen as an aspect of accounting that is suitable for legal review and offering the highest level of assurance (Apostolou, Hassell & Webber, 2000).

Methods Using purposive sampling, 17 heterosexual HIV positive men were recruited through community based organization to participate in two hours focus group discussions or 45 min in-depth interviews that were audio-recorded. Without using the word stigma, discussions and interviews were guided by four questions that explored participants’ experiences of living with HIV/AIDS. Interviews and discussions were conducted in three languages: English, Yoruba and Pidgin English. Thematic data analysis approach was in coding transcribed data, while social constructivist thinking guided data analysis. Results Participants ranged in age from 30 to 57 years old, and all were receiving antiretroviral therapy. Findings indicated that participants’ experiences of stigma might be moderated by the social context surrounding their HIV diagnosis, and whether they have met the socio-cultural construction of masculinity. Participants whose diagnosis were preceded by immediate family members’ diagnosis were less likely to report experiencing HIV stigma and more likely to report “not feeling less than a man” and educating others about HIV/AIDS. Contrarily, participants whose diagnosis was preceded by their own sickness were more likely to report isolation, sigma and feeling of being less than a man. All participants reported limiting their sexual intimacy, and those with children reported adjusting how they performed their role as fathers.

The stages of abattoir wastewater treatment were evaluated through determination of physicochemical parameters such as pH, conductivity, total dissolved solid, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, phosphate, nitrate and iron using standard procedures. Bacterial plate counts were determined using the pour plate method with nutrient agar. Characterization and identification of bacteria was done on the basis of cultural appearance of colony, morphology, differential and selective media. The results showed that Escherichia sp., Pseudomonas sp., Enterobacter sp., Klebsiella sp., Staphylococcus sp., Salmonella sp., Streptococcus sp. were common to both abattoir wastewater samples. Serratia sp. was identified only in Ikpoba Hill abattoir wastewater. The bacteria occurrence frequency revealed that Escherichia sp. was dominant (P>0.05) in both abattoir samples while Streptococcus sp. was least abundant. Bacterial plate count revealed significant increase in both abattoir wastewater samples. BOD5/COD ratio revealed that degradation was slow below normal limit of 0.6, and then significantly increased with time. Physicochemical parameters showed significant difference at P>0.05 for both abattoirs.

The stages of abattoir wastewater treatment were evaluated through determination of physicochemical parameters such as pH, conductivity, total dissolved solid, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, phosphate, nitrate and iron using standard procedures. Bacterial plate counts were determined using the pour plate method with nutrient agar. Characterization and identification of bacteria was done on the basis of cultural appearance of colony, morphology, differential and selective media. The results showed that Escherichia sp., Pseudomonas sp., Enterobacter sp., Klebsiella sp., Staphylococcus sp., Salmonella sp., Streptococcus sp. were common to both abattoir wastewater samples. Serratia sp. was identified only in Ikpoba Hill abattoir wastewater. The bacteria occurrence frequency revealed that Escherichia sp. was dominant (P>0.05) in both abattoir samples while Streptococcus sp. was least abundant. Bacterial plate count revealed significant increase in both abattoir wastewater samples. BOD5/COD ratio revealed that degradation was slow below normal limit of 0.6, and then significantly increased with time. Physicochemical parameters showed significant difference at P>0.05 for both abattoirs. These results suggest that temporal variations of the effluent bacterial community may be useful to predict the wastewater treatment performance and settleability of activated sludge.

While culture on the other hand has a negative and statistical significant effect on workplace satisfaction, this was likely to be true since punctuality, individual comportment, and work ethics were likely factors that member of working groups take seriously when working as a team in groups. The horizontal flow of information (knowledge transfer) was also found to depend on work group output performances.

Language had a positive and significant effect on workplace performance; this was also probably true since effective communication skill was likely to make working groups work in a hitch free manner. While culture on the other hand has a negative and statistical significant effect on workplace satisfaction, this was likely to be true since punctuality, individual comportment, and work ethics were likely factors that member of working groups take seriously when working as a team in groups. The horizontal flow of information (knowledge transfer) was also found to depend on work group output performances. This was reasonable, since how efficient work groups and sub groups within the groups efficiently carried out their tasks will depend on the horizontal flow of information in groups. The evidence presented in this study shows that issues of nationality was not relevant to individual group members overall satisfaction in participating in groups nor was it vital to overall group performances. The results could be beneficial to organization management particularly those that wish to improve overall output productivity since class work groups experimental studies are a miniature study of organizations, the implications of this study is that language and culture could improve organizational output productivity substantially since language could contributes significantly to organizational performances and work ethics is also likely to create workplace satisfaction which can contribute in a significant way to organizational output. |

Results: A total of eight fractions (F1, F2, F3, F4, F5, F7, F8, F9) obtained from the leaves of C. odorata were analyzed for their chemical constituents. They contain essential oils which were: α-pinene, β-pinene, 1,8-cineole, σ-elemene, terpineol, camphene, cymene, linalool, terpinolene and α-phallandrene. Free fatty acids were also identified: namely, hexanoic acid (caproic acid), dodecanoic acid (lauric acid), decanoic acid (capric acid) and octanoic acid (caprylic acid). Constituents common in fractions F2 and F3 with the highest anti-MRSA activities were: α-pinene, camphene, octanoic acid and decanoic acid. Conclusion: C. odorata is a promising anti-MRSA agent that can be explored for the synthesis of novel drugs for use in the treatment of MRSA infections.

The acute (LD50) and sub acute toxicity studies of the extract were determined using subcutaneous route in mice. In the sub-acute toxicity of the extract assessed, the following antioxidants indices (Superoxide Dismutase (SOD),Catalase (CAT), Reduced Glutathione (GSH), Nitric Oxide (NO), and Lipid Peroxidation (MDA)) were done using standard spectrophotometric methods to determine the level of toxicity. The novelty-induced behaviours were carried out in malaria infection using suppressive, curative and prophylaxis mode of malaria treatment. The analgesic effect of the extract was also investigated using three modes of nociceptive induced stimuli through acetic acid (chemical) induced-, hot-plate and tail flick (thermal) induced- nociception. Morphine, naloxone and acetylsalicylic acid were used as standard drugs to determine the mechanism of action. The result showed that the acute LD50 was 140 mg/kg which was an indication that the extract may be toxic. The extract reduced MDA and elevated the content of SOD, CAT, GSH and NO. Thus, overproduction of NO may therefore be the probable mechanism through which the extract exerts the indicated toxicity.
