Background Adansonia digitata (L) fruit has a multi-purpose function one among many, is the antioxidant activities of the fruit by preventing oxidative stress. The effect of Adansonia digitata (L) fruit on lead-induced liver and kidney damage is not clear. Hence, the study was aimed to assessed the protective role of Adansonia digitata (L) fruits against lead acetate induced changes in the liver and kidney function test parameters and the histology of both organ in experimental rats. The rats were divided into five groups with five rats each. All the rats were administered with respective assigned treatment once daily for 6 weeks. Rats in groups I were administered with just distil water (2 ml/kg). Rats in groups II were administered with lead acetate (30 mg/kg) while rats in groups III–V were administered Adansonia digitatata (L) fruit extract (250 mg/kg and 500 mg/kg) and Succimer (5 mg/kg) respectively, then additionally challenged with lead acetate (30 mg/kg) immediately after. At the end of the administration, the blood serum from the experimental rats were used for biochemical analysis. Then, the the organs such as the liver and kidney collected for histological study. Results Rats administered with Lead acetate showed an increase in AST, ALP and ALT as well as increase in urea and creatinine level (p < 0.001), when compared with the control group (group I), where as Adansonia digitatata (L) fruit prevented the effect (upsurge of serum, Urea, Creatinine, AST, ALP and ALT) of lead acetate. Rats administer with only Lead acetate revealed marked liver steatosis and the degeneration of the kidney glomerulus. The Adansonia digitatata (L) fruit extract and Succimer prevented the histological liver steatosis, as well as the degeneration of the glomerulus of the kidney cytoarchitecture. Conclusion The findings in this study suggest that Adansonia digitata fruits extract has a protective potentials against lead acetate induced liver and kidney toxicity by preventing the upsurge of liver function enzymes and kidney function parameters. Hence, Adansonia digitata fruits can serve as a natural plant agent that can prevent hepato-renal toxicity. Therefore, Adansonia digitata holds future prospects in preclinical framework to ameliorate organs toxicity for oral therapeutic applications.

Objectives The objective of this study was to evaluate the therapeutic effects of balanitoside in diabetic rats. Methods Twenty-five rats were divided into five groups. Rats in groups 2 to 5 were treated with streptozotocin to induce hyperglycemia. In addition, rats in groups 1 and 2 received 1 mL of distilled water, whereas those in groups 3, 4, and 5 received 10 and 20 mg/kg balanitoside and 6 U/kg insulin, respectively, for 14 days. All rats were sacrificed on day 15, blood samples were collected, and serum levels of alkaline phosphatase (ALP), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured. The liver was processed for examination under a light microscope. Results The results showed a significant decrease in liver protein concentrations in diabetic control rats, compared to those in the normal control rats and rats treated with 10 mg/kg balanitoside ( p < 0.05). There was no significant difference in ALP levels among all groups. However, a significant increase in ALT and AST levels was observed in the diabetic control rats, compared to those in the normal control rats ( p < 0.05). Photomicrographs of the liver of the diabetic control rats showed fat and glycogen droplets, vacuolated nuclei, and loss of cellular boundaries, whereas those of the rats treated with balanitoside or insulin showed a small amount of microvesicular fat droplets and slight infiltration of lymphocytes. Conclusion The findings of this study suggest the therapeutic effects of balanitoside in the liver of diabetic rats.
