Acute toxicity and histopathological changes in livers of frog tadpoles (Hoplobatrachus rugulosus) exposed to bioinsecticides derived from Azadirachta indica A. Juss., Stemona curtisii Hook.F., and Mammea siamensis

Ipomoea aquatica (IA) with antioxidant properties is used in therapeutic trends. An organophosphate, dichlorvos (Dich), is a common insecticide with various side effects on living tissues. This study examines the role of IA on Dich-induced hepatotoxicity in male rats. Sixty-four male rats were divided into eight groups including sham, Dich (4 mg/kg/day, intraperitoneally), IA 1, 2, and 3 (250, 500, and 1000 mg/kg/day, respectively, orally), and Dich + IA 1, 2, and 3. All treatments were applied daily for 60 days. At the end of the treatment, the animals were sacrificed. The histopathological changes, leukocyte infiltration, and apoptosis were assessed by light and fluorescent microscopy. The serum levels of hepatic enzymes, nitrite oxide (NO), and total antioxidant capacity (TAC) were evaluated biochemically. Dich statistically significantly increased the NO level, hepatic enzyme activity, apoptosis, leukocyte infiltration, the mean diameter of hepatocytes (DHs), and central hepatic vein diameter (CHVD) and also decreased the TAC, mean weight of liver, and the total weight of rats compared to the sham group (P < 0.01). In all IA and Dich + IA groups, a statistically significant decrease was detected in apoptosis, leukocyte infiltration, hepatic enzyme activity, NO level, mean DH, and CHVD, whereas an increase in TAC level, mean liver weight, and total weight was detected compared to the Dich group (P < 0.01). IA, due to the antioxidant property, recovers the Dich-related catastrophic changes in liver.
