Anti-ischemic effect of Aurantii Fructus on contractile dysfunction of ischemic and reperfused rat heart.
Aurantii Fructus (AF) is one of the most well-known traditional herbal medicines frequently used for the treatment of cardiovascular symptoms in Korea. The anti-ischemic effects of AF on ischemia-induced isolated rat heart were investigated through analyses of changes in perfusion pressure, aortic flow, coronary flow, and cardiac output. The subjects in this study were divided into two groups: an ischemia-induced group without any treatment, and an ischemia-induced group with AF treatment. There were no significant differences in perfusion pressure, aortic flow, coronary flow, and cardiac output between them before ischemia was induced. The supply of oxygen and buffer was stopped for 10 min to induce ischemia in isolated rat hearts, and AF was administered during ischemia induction. AF treatment significantly prevented decreases in perfusion pressure, aortic flow, coronary flow, and cardiac output under ischemic conditions (p < 0.01). These results suggest that AF has distinct anti-ischemic effects through recovery of contractile dysfunction in ischemic heart.
