V. Stetsuk, V. I.

Biochemical parameters on the 180th day of the experiment showed a shift in NO synthesis from constitutive NO synthases to inducible NO synthase and increased oxidative stress due to an increase in the production of superoxide anion radical and a decrease in antioxidant protection. 3. Quercetin protects rat testicular tissue from oxidative damage caused by the administration of triptorelin on the 180th day of the experiment by increasing the antioxidant defense and reducing reactive oxygen species.entestisratsquercetininterstitial endocrinocytesNO synthasemacrophagesArticle616.681:615.35:599.323.4
