Dexpanthenol attenuates lipid peroxidation and testicular damage at experimental ischemia and reperfusion injury

Prevention of tissue damage after testicular torsion caused by I/R injury is still a clinical and experimental problem. There are many experimental studies made with several chemicals in the literature for decreasing the effect of reactive oxygen species after ischemia and reperfusion. Dexpanthenol (Dxp) is the biologically active alcohol of pantothenic acid. Pantothenic acid increases the content of reduced glutathione, Coenzyme A and ATP in cell. We studied the effect of Dxp on lipid peroxidation and testicular damage. Forty adult rats were separated randomly into five groups: group Sh, Sham-operation; group TD, torsion-detorsion; group NS, torsion-normal saline-detorsion; group D, torsion-Dxp 250 mg/kg detorsion; group D2, torsion-Dxp 500 mg/kg detorsion group. Serum MDA levels were taken before detorsion, after torsion at the first and fifth minute and at the first hour. Tissue sample was taken at the first hour. The alterations of I/R injury on testis were histological graded. Serum MDA levels were significantly lower in group D2 compared to all groups. The histopathology score of group D2 was significantly lower than groups TD, NS and D. Histopathological score and serum MDA levels are strikingly compatible. Dxp attenuated lipid peroxidation and tissue damage at I/R injury. This effect depends on its antioxidant effect with increasingly reduced glutathione, Coenzyme A and ATP. The effect of Dxp on I/R injury has been shown for the first time in the experimental testicular torsion.
