Abstract

For centuries, Turkey has been a significant location here around 80 species of Hypericum with differing names widely occur, which is also known as Turkish folk medicine in treating some bacterial diseases as well as stomach and intestine inflammation. Recent studies have reported this herb family to contain numbers of bioactive compound contents. The study aims to investigate the protective effects of Hypericum triquetrifolium Turra (HT) upon oxidative stress and apoptosis in a rat model in which testes injury was induced by CP. The testicular injury was caused using CP (150 mg/kg). The rats were treated with a single dose (100 mg/kg) of methanol extract of HT to investigate various biochemical markers in the serum and plasma of blood samples apart from assessing the prognosis of CP-induced testicular damage. Added to that, histological analyses were performed to identify possible structural changes and apoptotic indicators, like Bax, Caspase-3, and Bcl-2. In CP Group, there was a rise in the levels of total oxidant status (TOS), malondialdehyde (MDA), oxidative stress index (OSI), Caspase-3, and Bax while superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), Bcl-2, and total antioxidant capacity (TAC) all decreased. Also, our histological analysis showed damaged testes. On the other hand, neither biochemical nor histological analysis showed testicular damage in HT Alone Group. In CP + HT Group, a significant number of the negatives changes due to CP were observed to have improved remarkably following an HT treatment. This study results suggest that HT could help improve CP-induced testicular injury thanks to its anti-oxidative and anti-apoptotic properties.
