Abstract

The present study was undertaken to investigate the protective roles of Adansonia digitata (African baobab) Cucumeropsis mannii (Melon), Abelmoschus esculentus (Okro),  on lipid profile, bone health, and selected organs (liver, kidney, brain, and testis) against cadmium-induced toxicity in rabbits. Twenty male rabbits were grouped into five with four rabbits in each group. Group 1 served as positive control and received standard feed and 1.5 mg/kg body weight normal saline, group 2 served as negative control and were exposed to 1.5 mg/kg body weight cadmium chloride, group 3 received 1.5 mg/kg body weight cadmium Adansonia digitata supplemented feed, group 4 received 1.5 mg/kg body weight cadmium chloride and Citrullus lanatus supplemented feed, while group 5 were given 1.5 mg/kg body weight cadmium chloride and Abelmoschus esculentus supplemented feed. All administrations were orally and lasted for 28 days. At the end of the administration, blood, liver, kidney, brain, and testes were harvested from the rabbits for biochemical and histological analysis. One-way analysis of variance followed by Turkey’s test was used to analyze the results with p < 0.05 considered significant. The results revealed that cadmium exposure caused a significant increase in serum total cholesterol, triacylglycerol, low density lipoprotein cholesterol concentration, and atherogenic index in rabbits exposed to cadmium. Cadmium exposure also reduced bone calcium concentration. Adansonia digitata maintained the atherogenic index of plasma at 2.67 compared with the positive control group (2.66). The three vegetables reversed the cadmium-induced up-regulation of total cholesterol and triacylglycerol in the liver, kidney, and brain but not in the testis. All the vegetables also restored bone calcium. Citrullus lanatus and Abelmoschus esculentus prevented organ damage induced by cadmium exposure. These vegetables however play different protective roles against cadmium exposed rabbits.
