Therapeutic effects of apocynin on ovarian ischemia-reperfusion induced lung injury
BIOTECHNIC & HISTOCHEMISTRY(2022)
Abstract
Ovarian ischemia-reperfusion (I-R) injury may damage remote organs, including the lungs. We investigated whether apocynin, a NADPH oxidase inhibitor, might protect against ovarian I-R induced apoptosis in the lungs of rats. Bilateral ovarian I-R was induced for 3 h, then apocynin was applied at two concentrations. Lung tissue was evaluated using spectrophotometric and immunohistochemical methods. We found that I-R increased total oxidant status (TOS), oxidative stress index (OSI) and myeloperoxidase (MPO) levels, and immunostaining of nuclear factor kappa-B (NF-kappa B), light chain 3B (LC3B), interleukin 1-beta (IL-1 beta), caspase-3 and tumor necrosis factor-alpha (TNF-alpha), but decreased superoxide dismutase (SOD) values. Apocynin application to I-R injured rats enhanced recovery of lung tissue oxidants and improved both histology and frequency of apoptosis.
