Özet

The aim of this study was to investigate potential antioxidant and antifibrotic effects of Ziziphus jujube (ZJ) in a cavernosal nerve injury (CNI)-induced erectile dysfunction (ED) rat model. Forty-eight male rats were assigned to six-sized groups as group 1: sham-operated; group 2: sham-operated + low-dose ZJ (200 mg/kg); group 3: sham-operated + high-dose ZJ (400 mg/kg); group 4: CNI + distilled water; group 5: CNI + low-dose ZJ; and group 6: CNI + high-dose ZJ. At the end of 2 weeks, intracardiac blood was taken and rats were sacrificed. For biochemical analysis, cavernosal transforming growth factor-beta-1, collagen type I and type 3, fibronectin, alpha and beta actin were examined in plasma and cavernosa. Superoxide dismutase (SOD), catalase (CAT), malondialdehyde (MDA) and prolidase levels were measured in serum to evaluate antioxidant effect of ZJ. Histopathological examination of tissues revealed that highest fibrosis rate was in group 4 (66.84%). Collagen 1 and 3, alpha and beta actin, fibronectin levels were significantly different among groups (p < .05). Differences between plasma SOD, CAT, MDA and prolidase were also significant among those groups (p < .05). In this study, antioxidant and antifibrotic effects of ZJ were determined in the corporal tissue after CNI. It is thought that ZJ may be beneficial on ED patients especially after radical pelvic surgeries.
