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 study was carried out with the aim to determine the antimicrobial effect of ethanolic leaf extract of Mitracarpus scaber against some clinical isolates. The leaves were screened for some phytocompounds using standard analytical methods.The antimicrobial activity of the leaf extract against Escherichia coli, Staphylococcus aureus and Candida albicans was carried out using agar well diffusion and broth dilution methods. The results of phytochemical studies revealed the presence of alkaloids, flavonoids, cardiac glycosides, triterpenes, phytosterols, tannins, and saponins.

The present study explored the use of anatomical characters of Sataria barbata and Brachiaria deflexia as indicators of waste engine oil pollution. Four (4) kg of air dried soil was measured into perforated plastic buckets and treated with waste engine oil to obtain different concentrations [0% (control), 2%, 4%, 7% and 10%] on volume to weight basis. The experiment was set up in 3 replicates. The soil samples were allowed to stand for seven days before seedlings were planted. The plants were harvested after 8 weeks of transplanting.

This study was carried out to determine the bacterial and fungal flora of soils contaminated with used automobile engine oil at a mechanic workshop at AKAD community, Akure, Ondo State, Nigeria, with the aim of testing their ability to degrade diesel oil. Isolation and identification of microbes were done using standard microbiological techniques. Oil degrading activity of the isolates were assayed for using Bushnell Haas broth (BHB) supplemented with 1% diesel oil.
