Histomorphological and biochemical changes induced by triptolide treatment in male lesser bandicoot rat, Bandicota bengalensis.

Mature and healthy male lesser bandicoot rats, Bandicota bengalensis (n = 40) were fed on bait (mixture of cracked wheat and powdered sugar in 98:2) containing different concentrations of triptolide (0, 0.15, 0.20 and 0.25% w/w) for 15 days in two-choice trials. Results revealed no significant effect of triptolide treatment on weights of vital organs after 30 and 60 days of treatment withdrawal. A significant (P ≤ 0.05) increase in plasma levels of TP, ALP, ACP, ALT and AST in response to stress induced in groups of rats treated with 0.20 and 0.25% triptolide was observed after 30 days of treatment withdrawal. No significant effect of treatment was observed on histomorphology of liver. A significant (P ≤ 0.05) effect of triptolide treatment was, however, observed on testicular function in the form of reduced diameter of seminiferous tubules and number of various spermatogenic cells indicating effect on spermatogenesis and spermiogenesis. The cell stages affected did not recover fully within 60 days period following treatment withdrawal. The present study suggests the potential of triptolide in the reproductive management of B. bengalensis by way of affecting testicular function.
