PURPOSE: To evaluate the protective role of dimethylsulfoxide (DMSO) in a rat model of testis ischemia/reperfusion (I/R). METHODS: Twenty-four male Wistar rats were randomized in two equal groups. Control rats (G-1) received saline 2.0 ml intraperitoneally (ip) 21, 9 and 1 h before torsion. Experimental rats (G-2) received ip injections of 3% aqueous solution of DMSO, 0.1ml/10g body weight. Saline was added to complete 2.0ml when necessary. I/R injury was induced in anesthetized rats by torsion of the right testis lasting 3 hours. Testis and blood samples were collected at the end of ischemia (T-0) and 3 hours later (T-3) for assessment of testis malonaldehyde (MDA), reduced glutathione (GSH), and plasma total antioxidant power (TAP). RESULTS: MDA levels decreased significantly in G-2 rats compared with G-1 animals in all time-points. GSH levels increased significantly in T-0 and T-3 time-points in DMSO pretreated rats compared with G-1 rats. GSH levels increased significantly during reperfusion in G-2 rats. TAP was similar in both groups denoting absence of systemic effects in this study. CONCLUSION: Pretreatment with DMSO reduces testis lipid peroxidation and oxidative stress caused by torsion/detorsion of the testis.
