Aim: The aim of this study was to investigate the protective effects of bioflavonoid compounds i.e. rutin and naringin on gentamycin induced testicular oxidative stress in rats.
Method: A total of 42 male wistar albino rats were divided in to 7 groups, each contains 6 rats. Gentamycin, 5 mg/kg, I.P was administered to the rats from day 1 to day 10. Rutin and naringin were given in different doses (5mg/kg, 10/kg) for a period of 35 days from day 1 to day 35 to the gentamycin treated animals. A sham control group animals with water, control group animals with gentamycin and vehicle control group animals with 0.1% sod CMC were also maintained until completion of 35 days. On 36th day bilateral orchiectomies were performed for all the animals. The testicular tissue was evaluated for various sperm parameters, biochemical estimations and histological changes.
Result: Animals treated with 5mg/kg and 10mg/kg of rutin and naringin (Groups 4, 5, 6, 7) have shown significant and dose dependent reduction in MDA levels and increase in levels of antioxidant enzymes, SOD and Catalase when compared to control group animals (Group 2). Sperm count, motility, viability were also protected and normalized with rutin and naringin. Specimens from group 2 had a histological injury with disordered germinal cells. Drug treated groups shown improved testicular architecture. Rutin was more effective in all the parameters when compared to Naringin. Both the bioflavonoids were effective in reducing the gentamycin induced testicular oxidative stress.
Conclusion: Rutin and Naringin pretreatment have shown protective and beneficial effect on gentamycin induced oxidative stress in rats.
