Co-administration of Salvia miltiorrhiza and verapamil inhibits detrimental effects of torsion/detorsion on testicular tissue in rats.

Abstract

Testicular torsion/detorsion is one of the important emergencies that requires fast surgical intervention. This study aimed to investigate the effects of Salvia miltiorrhiza hydroalcoholic extract combined with verapamil on testicular ischaemia/reperfusion damage in Wistar albino rats. All animals were distributed in 3 groups (n=8), including the sham-operated group, torsion/detorsion (TD) group and torsion/detorsion+pretreatment with 200mg/kg Salvia miltiorrhiza extract combined with 0.3mg/kg verapamil (SMV) group. Oxidative stress biomarkers (MDA, GPx, CAT and TAC) both in plasma and testicular tissue, sperm parameters (motility, vitality, concentration and morphology) and histopathological parameters (MSTD, GECT, Johnson's score, Cosentino's score and testicular cell thickness) were assessed in all groups. Ischaemia/reperfusion significantly increased MDA and decreased GPx, CAT and TAC levels (p<.05). Pretreatment with SMV significantly increased GPx, CAT and TAC levels (p<.05). SMV group increased progressive sperm motility and vitality and reduced non-progressive motility of spermatozoon (p<.05). Testicular torsion significantly decreased all histopathological parameters compared to the sham group (p<.05). SMV pretreatment remarkably increased MSTD, GECT and Cosentino's score in comparison with the TD group (p<.05). A combination of Salvia miltiorrhiza with verapamil could reduce damages triggered by testicular torsion detorsion and improve sperm functionality parameters and oxidative stress defence systems.
