Vernonia amygdalina, Ocimum gratissimum and Talinum triangulare Mitigates Kidney Toxicity in Male Wistar Rats Administered with Dichlorvos

This study aimed to evaluate the therapeutic potentials of extracts from medicinal plants (Vernonia amygdalina, Ocimumgratissimum, Talinum triangulare) against DDVP-induced renal toxicity in Wistar rats. A total of 50 male adult rats, each weighing approximately 272g, were divided into ten groups (n=5). The groups were given normal saline (normal control), 8.0mg/kg body weight DDVP (positive control), 8.0mg/kg body weight DDVP along with 200mg/kg and 400mg/kg body weight of the plant extracts respectively, and 20mg/kg and 40mg/kg body weight of vitamin C for 28 days. DDVP significantly (P<0.05) increased urea, creatinine, Na+, K+, Cl-, and significantly (P<0.05) decreased HCO3- compared to the normal control. Treatment with the aqueous leaf extracts of Vernonia amygdalina, Ocimumgratissimum, and Talinum triangulare significantly corrected these biochemical imbalances when contrasted with the positive control. Histology of the kidney tissues supported these findings. In conclusion, the aqueous leaf extracts of Vernonia amygdalina, Ocimumgratissimum, and Talinum triangulare may have therapeutic potential against DDVP-induced renal toxicity in rats.
