Protective effects of propolis on ischemia-reperfusion injury in a rat testicular torsion and detorsion model

Vet Res Forum. 2023;14(7):389-395. doi: 10.30466/vrf.2023.1972630.3682. Epub 2023 Jul 15.ABSTRACTThe torsion model of testis in a rat was adopted for evaluation of possible effects of propolis (Prop) on ischemia-reperfusion (IS/REP) injury. The healthy male Wistar rats (totally 24 animals) were randomized into four groups (n = 6) and animals experienced bilateral testicular torsions as follows: In sham group just, laparotomy was performed and in IS group, animals experienced a 3 hr period testicular IS. In IS/REP group, a 3 hr period of IS followed by a 3 hr period of testicular REP for left testis and a one-week testicular REP for right testis were done. In this group animals were gavaged by 1.00 mL normal saline 1 hr before the onset of IS. In IS/REP/ Prop group, the same procedures for IS/REP animals were followed as well as gavage of 1.00 mL Prop extract solution 1 hr before the onset of IS. Analyses of biochemistry, histology, inflammatory biomarkers and sperm parameters were carried out. In IS/REP/Prop group, nitric oxide synthase malondialdehyde, myeloperoxidase and 8-hydroxy-2 deoxyguanine in IS/REP/Prop group were significantly decreased and, superoxide dismutase, total glutathione, glutathione peroxidase, glutathione reductase and glutathione S-transferase were significantly increased compared to the other animals. In IS/REP/Prop group, seminiferous tubules (with normal spermatogenesis) showed all stages of spermatogenic cells with plentiful spermatozoa. Tubular det...
