The toxicity of hair dressing salon effluent on Clarias gariepinus juveniles was studied using static bioassay method. This study investigated haematological, histopathological and biochemical changes in Clarias gariepinus juveniles. The fish samples were distributed randomly into T1 (800 ml/L), T2 (600 ml/L), T3 (400 ml/L), T4 (200 ml/L), and T5 control (water alone). All samples were studied in three replicates, in a completely randomized experiment. Mortality increased with  increased effluent concentrations; 250.96 ml/L was recorded as LC50 for 96 h.

The aim of this study was to ascertain the effects of peanut diet supplementation on glucose metabolism in rats exposed to 1, 2-dimethylhydrazine. Lactate dehydrogenase and glucose -6-phosphate dehydrogenase activities were used as indices for glucose metabolism. Eighty-four rats of both sexes were used for this study and were divided into seven groups of 6 rats each. 1, 2- dimethylhydrazine (DMH) was administered subcutaneously at a dose of 25 mg/kg body weight.Group A rats were maintained on rat feed, group B rats were maintained on rat feed and administered DMH once weekly for 12 weeks.

This study was conducted to determine the noise exposure level and the association between self-reported health effects and risk factors among workers in auto mechanic workshops in Abeokuta town, Nigeria. Noise levels were measured at selected auto mechanic sites. A cross-sectional study was also conducted among fifty workers using a wellstructured questionnaire across the sampling sites. The recorded noise level in the morning and afternoon ranged between 61.3 - 75.8 dB and 70.4 and 86.4dB respectively.

Hydro-priming is an important seed treatment technique for rapid seed germination. Cola species exhibits long and uneven germination. Hence this study was aimed at investigating the effect of hydro-priming durations on the germination and seedling growth of Cola parchycarpa and Cola rostrata. Five treatments (hydro-priming durations of 0 hour, 24 hours, 48 hours, 72 hours and 96 hours) were used and the experiment was laid out in a completely randomized design (CRD) with 6 replicates each. In C.

Cola rostrata and Cola parchycarpa are under-utilized indigenous kola plants, known as achicha by the Igbo natives in Nigeria, whose fruit pulps are edible and tasty. The proximate, vitamins, minerals and phytochemicals constituent of the fruit epicarp, fruit pulp and seed of C. rostrata and C. parchycarpa were evaluated using standard analytical laboratory procedures. The results revealed that C. rostrata and C. parchycarpa fruit pulps contained high moisture contents (56.56 % and 58.83 %) and carbohydrates (31.30 % and 55.39 %) respectively.

 The use of combination of artificial sweeteners, most importantly aspartame (E951) and acesulfame potassium (E950) in foods, beverages and other products is on the increase despite reports on their side effects. This study investigated the effects of combination of tolerable daily dose of both aspartame and acesulfame-k on blood glucose, lipids and cytokines of female Wistar rats. Twenty-five female Wister rats weighing 90.7±8.1 g were randomly assigned into five groups.

Global focus is currently on water, sanitation and hygiene (WaSH) due its public health and environmental significance. The aim of this study was to investigate the Water, Sanitation and Hygiene status of Uwelu and Evbareke spare parts markets in Benin City. Questionnaires were administered to evaluate the WaSH status of the markets. Physicochemical and bacteriological qualities of borehole water samples at the spare parts markets were investigated adopting standard analytical procedures and pour plate techniques respectively.
