ECFect of Yang Xin Kang on Plasma Endothelin and Calcitonin - Gene Related Peptide Levels in Rats with Myocardial Hypertrophy Heart Failure / 广州中医药大学学报

[Objective] To observe levels of plasma endothelin (ET) and calcitonin gene - related peptide (CGRP) in rats with myocardial hypertrophic heart failure affected by Yang Xin Kang (composed of Radix Ginseng, Radix Ophio-pogonis, Radix flicis Pubescetis, etc.) and its mechanism. [Methods] Rat models with myocardial hypertrophic heart failure was established by subcutaneous injection of isoprenaline for 13 days. Fifty rats were allocated to five groups: normal control (Group A), model (Group B), digoxin (Group C), high dosage of Yang Xin Kang (Group D) and low dosage of Yang Xin Kang (Group E). ET and CGRP levels were measured by radioimmunoassay method. [Results] ET level in Group B was higher and CGRP level lower than those in Group A (P
