Desplatsia dewevrei (De Wild. & Th. Dur.) Burret fruits were investigated for possible anti-fertility and profertility activities by hematological, biochemical and hormonal assays using Wistar rats of both sexes for 6 weeks. Methanol extract of Desplatsia dewevrei fruits was administered orally at 50 and 100 mg/kg. Results show that concentrations above 50 mg/kg interfered with the reproductive development of the liter (fetus) in female rats. While in male rats, doses above 50 mg/kg posed adverse effect on sperm count and sperm motility.

Flood can be seen as a process that bring about a short-term immersing of a land with water that does not ordinarily occur. It is one of the most common environmental hazards in developing countries like Nigeria. Flooding, a recurrent events in Nigeria occur mostly in locations that are flat or low lying especially places with inadequate or no surface drainages, or where existing ones have been filled with refuse and other sediments. The exposure to flooding is due to a range of socio-economic factors, like income, occupation, information technology, access to loan facilities, etc.

A seven month study was carried out between August 2020 and February 2021, to assess the physicochemical parameters of Ajiwa and Zobe reservoirs in Katsina State, Nigeria, with a view to understanding the pollution status of the water bodies. Selected water quality parameters were assessed using standard methods, these include temperature, pH, dissolved oxygen (DO), hardness, turbidity, alkalinity and ammonia-nitrogen.

The methanol extract of Annona muricata leaf was investigated for its effects on blood glucose, haematology, serum electrolyte and kidney parameters of alloxan-induced diabetic mice. Six groups of mice (5 mice per group) was used for this study. Group A served as “Normal control” and fed mice pellets and water. Diabetes was induced in Groups B, C, D, and E by intraperitoneal injection of alloxan (90 mg/kg).

The methanol extract of Annona muricata leaf was investigated for its effects on -cell dysfunction, and atherogenenic dyslipidaemia in alloxan-induced diabetic mice. Thirty (30) mice of both sexes, aged between 8-10 weeks were randomly divided into normal, diabetic, diabetic + glibenclamide(5mg/kg), diabetic+250 mg/kg A. muricata Extract, diabetic+500 mg/kg A. muricata Extract, diabetic+1000 mg/kg A. muricata Extract, groups (n=6/group). Alloxan was administered intraperitoneally while extracts and glibenclamide were given via oral route for 21 days. The results revealed that, 250 mg/kg A.

This study was carried out to investigate the antibacterial activities of commercially available alcohol-based handsanitizers (2Sure, Dettol and Carex) on some clinical bacterial isolates. The isolates were obtained from the laboratory stock culture of University of Benin Teaching Hospital, Benin City.

Herbs are increasingly used across the globe; In fact, the World Health Organization reported that most African countries, including Nigeria, depend on herbal medicines for primary health care, without much documented evidence of adverse effects. Agbo polyhebral extract is popular in Nigeria, especially among (but not limited to) the local populace of the southwestern areas. The aim of this study is to determine the effects of malaria alcoholic herbal extract (Agbo) on renal, liver, oxidative stress markers and hematological parameters on wistar rats.

 Fe (III) compounds which are formed from the oxidation of Fe(II) by iron bacteria precipitates, and forms iron oxides - an extensive orange mats of organic material, which is often found present in the ground water, evident by the rust stain colour seen on almost all the water storage tanks in Yenagoa, Bayelsa State, Nigeria. Hence, this study characterized iron bacteria diversity in groundwater, which is a major source of drinking water in the state.

The antibacterial activity of aqueous, ethanolic and methanolic extracts of Ricinus communis were studied by the agar diffusion method. The ethanolic extract produced the greatest antimicrobial activity and the aqueous extract the least. Staphylococcus aureus was the most sensitive to the extracts while Bacteroides fragilis was the most resistant. The minimum bactericidal concentration of the extracts ranged between 60% (w/v) and 100% (w/v). Thus the extracts of Ricinus communis could be useful as a source of antibiotics against aerobic and anaerobic bacteria.

Investigations based on field records and experiences at the Guinea Fowl Production Research Unit of the Kainji Lake Research Institute have shown that some diseases management conditions which include: yolksac, fungal infections, collibacillosis, helminthiasis, management problems in particular inbreeding, moulting, heatstroke and nutritional deficiencies affect significantly the reproductive organs, egg laying and hatchability.
