TLDR
The results of the present study provide clear evidence that the ethanolic ZO extract pretreatment enhances the antioxidant defense against ISO-induced oxidative myocardial injury in rats and exhibit cardioprotective property.
Abstract
Ethanolic Z. officinale (ZO) extract (200 mg/kg) pretreatment for 20 days in isoproterenol (ISO)-treated rats significantly increased the levels of endogenous myocardial antioxidants (catalase, superoxide dismutase and tissue glutathione), decreased the levels of serum marker enzymes (lactate dehydrogenase, creatine kinase, aspartate transaminase and alanine transaminase) and increased myocardial lipid peroxides. Histological examination of rat's heart section confirmed myocardial injury with ISO administration and near normal pattern with ethanolic ZO extract pretreatment. The results of the present study, for the first time, provide clear evidence that the ethanolic ZO extract pretreatment enhances the antioxidant defense against ISO-induced oxidative myocardial injury in rats and exhibit cardioprotective property.
