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).
