ABSTRACT
PURPOSE:
The aim of this study was to investigate the effects of new herbal formula (KBMSI-1) on erectile dysfunction in streptozotocin-induced diabetic rat model. MATERIALS ANDMETHODS:
We used male Sprague-Dawley rats aged 12 weeks and divided into three groups; control (n=8), diabetes (DM) (n=8), DM+KBMSI-1 200 mg/kg treatment (n=8) groups. The DM groups received a single intraperitoneal injection of streptozotocin (STZ). Distilled water was administered in the control and DM group. To investigate the penile erection, intracavernosal pressure (ICP) and intracavernosal pressure/mean arterial pressure (ICP/MAP) were recorded in all groups. Serial sections of the penis were used to perform Masson's trichrome stain. We analyzed the expression of nNOS and eNOS concentration in the isolated corpus cavernosum by western blotting.RESULTS:
Peak ICP/MAP ratio was markedly increased in the treatment group with KBMSI-1 compared with DM group (p<0.05). Masson's trichrome staining of corpus cavernosum showed increase in smooth muscle volume and the regular arrangement of collagen fibers in KBMSI-1 treatment group compared with DM group. Western blot analysis revealed that the penile expressions of nNOS and eNOS protein were significantly higher in KBMSI-1-treated group than in DM group.CONCLUSIONS:
This study showed that herbal formulation of KBMSI-1 enhances the penile erection and the level of eNOS and nNOS expression of penile corpus cavernosum in streptozotocin-induced diabetic rat model.
