Purpose : Diabetes mellitus produces disturbances in reproductive function including
decreased serum testosterone levels, however, the effects of diabetes on the contractile
function of testosterone-dependent urogenital smooth muscles have not been conclusively
established. In this study, the effects of streptozotocin-induced diabetes on the
contractile responses of rat seminal vesicle were compared with those of insulin-treated
diabetic and control groups.
Materials and Methods : Diabetes was induced by intraperitoneal injection of
streptozotocin(65mg/kg) and in insulin-treated diabetic group, NPH was daily injected by
subcutaneous route. All the rats were sacrificed by cervical dislocation after 6 weeks
and the seminal vesicles were immediately removed. The changes of contractile response
to electrical field stimulation, phenylephrine and KCI administration were measures by
polygraph
Results : 1. The weights of seminal vesicle in streptozotocin-induced diabetes were
significantly decreased than those of insulin-treated diabetic and control groups(p<0.05).
2. Contractile responses of seminal vesicle to electrical field stimulation were
significantly decreased in streptozotocin-induced diabetic compared to insulin-treated
diabetic and control groups(p<0.05). 3. Streptozotocin-induced diabetes produced
significant increase in contractile responses of seminal vesicle to phenylephrine and KCI
than insulin-treated diabetic and control groups(p<0.05).
Conclusions : This study demonstrates that diabetes produce a denervation-like
supersensitivity which is specific for receptor-mediated processes and that insulin
treatment in diabetic mellitus is able to recover the contractile responses of seminal
vesicle.
