Effect of calcitonin gene-related peptide (CGRP) on myocardial ischemic injury in rat / 中国病理生理杂志

ABSTRACT

AIM: To study the protective effects of intravenous (iv) CGRP on myocardial injury in rat. METHODS: Establish a rat myocardial ischemic injury model by subcutaneous injection of single dose of isoproterenol (ISO), and treat the model with single dose of iv CGRP. Two hours later, serum CK, LDH, MDA and SOD levels were measured, MDA and SOD in myocardial tissue were tested, and myocardial tissue structures were observed. RESULTS:(1) Serum MDA and tissue MDA levels increased significantly and serum SOD and tissue SOD decreased significantly in injury group, in the CGRP treated group, the above changes were reversed (P
