As a result this study determined the incidence of mycotoxigenic fungi in both commercial and privately milled concentrated poultry feeds. A total of 100 poultry feed samples consisting of 52 privately milled poultry feed and 48 commercial feed samples were collected. Mycoflora in the feed was determined. Nine fungi genera were isolated. The most frequently isolated fungi genera in both privately milled and commercial feed was Aspergillus spp which was about 40% of mould isolate. Penicillium spp is 20% in private feed and 13% in commercial feed. A total of 874 fungi were isolated consisting of 458 fungi species in privately milled feed and 416 fungi species found in commercial feed. Mycotoxigenic fungi genera, Aspergillus, Penicillium, Fusarium and Alternaria were isolated. Aspergillus flavus is the commonest isolated fungi species.

These infections can affect most population in endemic areas with major economic and social consequences. The miswak is a natural toothbrush made from the twigs of the Salvadora persica (Salvadoraceae). Miswak prevents tooth decay, eliminating toothaches and halt further increase in decay. The present study was undertaken to evaluate antihelmintic activity of aqueous and alcoholic root extract of S. persica against Indian earthworms Pheretima posthuma. Various concentrations (10, 20, 40 and 80 mg/ml) of aqueous and alcoholic root extract of S. persica were tested, which involved determination of time of paralysis and time of death of the worms. It was compared with Piperazine citrate (10, 20, 40 and 80 mg/ml) as standard reference and normal saline as control. The study indicated the potential usefulness of aqueous and alcoholic extract of S. persica against earthworm.

STUDY DESIGN: Cross-sectional. SETTING: Community. SUBJECTS AND METHODS: Subjects included elderly who were found apparently healthy following repeated examination by physicians. The pure tone average (PTA) for the speech and high frequencies, and the serum folate and cobalamin were determined and the correlation found. RESULTS: The mean Ϯ SD values of serum folate among the subjects with normal PTA in the speech frequencies (0-30 dB) was 412.revealed that low folate (correlation coefficient ϭ Ϫ0.27, P ϭ 0.01) and cyanocobalamin (correlation coefficient ϭ Ϫ0.35, P ϭ 0.02) were significantly associated with increasing hearing threshold in the high frequencies. After adjusting for age, serum folate (correlation coefficient ϭ Ϫ0.01, P ϭ 0.01) was significant, while vitamin B12 (correlation coefficient ϭ Ϫ0.01, P ϭ 0.74) was not. CONCLUSION: Serum folate was significantly lower among elderly with ARHL. Trials on nutritional supplementation may substantiate the role of serum folate in ARHL.

This prospective study involved 126 participants ≥ 60 years old who were found to be free of any medical conditions. Pure-tone averages for both the speech (500-2,000 Hz) and high frequencies (3,000-8,000 Hz) and serum IgG levels were determined. Using 30 dB as cut-off for hearing loss, the correlation with serum IgG was assessed. There were 59 males and 67 females with a mean age ± SD of 67.0 ± 2.7 years. Speech frequency hearing loss was seen in 30.2%, while high-frequency hearing loss accounted for 74.6%. In the speech frequencies, the mean ± SD of serum IgG among subjects with normal hearing was 11.3 ± 3.9 g/l, while among those with hearing loss it was 8.3 ± 3.3 g/l (p = 0.01). In the high frequencies, the mean ± SD values of serum IgG among the subjects with normal hearing was 11.1 ± 2.3 g/l, while among those with hearing loss it was 8.7 ± 1.9 g/l (p = 0.01). Low serum IgG may be a contributory factor to the development of ARHL among the elderly. However, a longitudinal study involving intervention with immunoglobulin supplementation may further confirm this role.

Over the next 2 decades, it is projected that there will be a rise in CVD mortality rates in the developing countries, linked to demographic changes and progressive urbanization. Nigeria has witnessed tremendous socio-economic changes and rural-urban migration which have led to the emergence of noncommunicable diseases. We set out to determine the prevalence of modifiable CVD risk factors among apparently healthy adult Nigerians. This is a descriptive cross-sectional study carried out at Katsina, northwestern Nigeria from March to May 2006. Subjects for the study were recruited consecutively from local residents, hospital staff and relations of in-patients of the Federal Medical Centre, Katsina using convenience sampling. Socio-demographic information, anthropometric measurements and blood pressure were obtained from the subjects in a standardized manner. Venous samples were collected for necessary investigations and analyzed at the hospital central laboratory. Findings: Three hundred subjects (129 males and 171 females) with a mean age of 37.6 ± 10.6 (range 18-75) years were studied. Prevalence of the modifiable cardiovascular risk factors screened for were as follows: generalized obesity 21.3% (males 10.9%, females 29.2%, p < 0.05), truncal obesity 43.7% (males 12.4%, females 67.3%, p < 0.05), hypertension 25.7% (males 27.9, females 24%, p > 0.05), type 2 diabetes mellitus 5.3% (males 5.4%, females 5.3%, p > 0.05), hypercholesterolaemia 28.3% (males 23.3%, females 32.2%, p < 0.05), elevated LDL-cholesterol 25.7% (males 28%, females 24%, p > 0.05), low HDL-cholesterol 59.3% (males 51.9%, females 65%, p < 0.05), hypertriglyceridaemia 15% (males 16.3%, females 14%, p > 0.05) and metabolic syndrome 22% (males 10.9%, females 30.4%, p < 0.05). Conclusions: We found high prevalence of CVD risk factors among apparently healthy adult Nigerians. In order to reduce this high prevalence and prevent subsequent cardiovascular events, encouragement of a healthy lifestyle is suggested.

It is important to appreciate factors associated with the disease so that a holistic approach can be taken in tackling the rising burden. The objective of this study was to determine the prevalence of overweight and obesity and the factors independently associated with obesity in an urban Nigerian population. Methods: A cross-sectional study of 300 healthy adult subjects was conducted in the urban city of Katsina, northern Nigeria. Relevant sociodemographic and clinical information were obtained. Screening for obesity was done using the Body Mass Index while relevant laboratory investigations were conducted. Univariate and multivariate logistic regression analyses were performed to determine the predictors of obesity. Results: Overweight and obesity was found in 53.3% and 21.0% respectively with a significantly higher prevalence in females compared to males (overweight: 62.0% vs 41.9%, p < 0.001; obesity: 29.8% vs 9.3%, p < 0.001). In univariate analysis, the odds of obesity were higher in women and in the presence of hypertension, hypercholesterolaemia and hyperuricaemia. However, in multivariate analysis, factors independently associated with obesity were female sex (OR 6.119, 95% CI 2.705-13.842, p < 0.001), hypercholesterolaemia (OR 2.138, 95% CI 1.109-4.119, p = 0.023) and hyperuricaemia (OR 2.906, 95% CI 1.444-5.847, p = 0.003). Conclusion: There is a high prevalence of obesity in northern Nigeria and women are significantly more affected. The high prevalence is independently associated with female sex, hypercholesterolaemia and hyperuricaemia. Public health education is urgently needed in order to reduce this burden and prevent other non-communicable cardiovascular disorders.

The decomposition rate constant (wk -1 ) ranged from 0.034 (Dactyladenia, subhumid zone) to 0.49 (Gliricidia, humid zone) in the rainy season, and from 0.01 (Dactyladenia, subhumid zone) to 0.235 (Pterocarpus, arid zone) in the dry season. The direct correlation between the decomposition rate of plant residues and their quality was only valid in agroeco-zones where there is not moisture stress. Similarly, the direct correlation between the decomposition rate of plant residues and moisture availability was only valid for plant residues with high quality. The decomposition rate of the low quality plant residue could increase from humid to arid zone in West Africa. In the arid zone, the low quality plant residue could also decompose faster than high quality plant residue. The climate-residue quality interactive effects on plant residue decomposition in West Africa were attributed to the feedback of low quality plant residue's mulching effect, soil fauna and appreciable photodegradation in dry regions. A decomposition equation that could be used to predict the decomposition rate of plant residues with various qualities
