Carbendazim generates symplasts in rat spermatogenic clones.
In order to find non-microtubular targets in the seminiferous epithelium for the fungicide and reproductive toxicant carbendazim, it was administered to 90 days old male Wistar rat in a single bolus dose of 400 mg/kg body weight through an oral intubation. A parallel control group was maintained. Rats were sacrificed 48 days after the treatment and the testes were analysed for histopathological changes adopting routine histological methods, when symplasts were localised. The maximum diameter of five largest symplasts was measured, and the number of nuclei in these symplasts was also determined. As it is known that symplasts of spermatogenic cells are produced due to opening up of the intercellular bridges between cells in a clone consequent upon disruption of actin microfilaments, the present study shows that actin microfilaments would also be targets in the seminiferous epithelium for carbendazim toxicity.
