Abstract

Spermatogenesis, a rapidly proliferating cell system, is highly susceptible to damage by radiotherapy and/or chemotherapy. Vindesine, a semisynthetic vinca alkaloid, was given as a single injection to adult male Swiss albino mice to study its effects on testicular weight and male germ cell turnover pattern using flow cytometry. Testicular weight declined significantly at Day 7 to 14 and from Day 14 to 35 after administration of 1 and 2 mg/kg b wt vindesine, respectively. Flow cytometric evaluation of various testicular cell types after the administration of 2 mg/kg b wt vindesine revealed a significant increase in the relative percentage of spermatogonial cells at Day 21 and 35 posttreatment. In contrast, the relative percentage of primary spermatocytes declined significantly at Day 7 and 14 posttreatment. Similarly, a significant reduction in the relative percentage of round spermatids was observed from Day 7 to 35 posttreatment. The relative percentage of elongated spermatids declined significantly at day 35 posttreatment. These changes are reflected in the transformation ratios. While the 4C:2C ratio did not exhibit any significant change below 1 mg/kg vindesine, it declined significantly after 1 mg/kg (Day 14) and 2 mg/kg (Day 7 to 35, except Day 28 posttreatment) vindesine treatment. Treatment of male mice with 2 mg/kg vindesine resulted in a significant decline in 1C:2C ratio from 7 to 35 d post-treatment. The 4C:S-phase ratio decreased significantly at Day 7 and 14 posttreatment for all the drug doses above 0.05 mg/kg. A significant reduction in the 1C:4C ratio was observed at day 21 to 35 posttreatment as a result of 2 mg/kg vindesine administration.
