Abstract
Catecholamine level in the blood, heart and adrenal tissues, and heart sensitivity to catecholamines were determined in 3-week-old rats after chemical sympathectomy. It was shown that tachycardia in sympathectomy rats was caused by increased heart sensitivity to catecholamines due to the reduction in their concentration.
摘要
在化学性交感神经切除术后，对3周龄大鼠的血液、心脏和肾上腺组织中的儿茶酚胺水平以及心脏对儿茶酚胺的敏感性进行了测定。结果表明，交感神经切除术后大鼠的心动过速是由于儿茶酚胺浓度降低导致心脏对儿茶酚胺的敏感性增加所致。
