[Role of musculocutaneous nerve in the relationship between "chutse" acupoint and heart].

Ligating fourty eight rabbits left ventricular branch of coronary artery made model of acute myocardial infarction (AMI) with indices of ECG and size of AMI. They were divided at random into four groups: "Chutse" acupoint group, cutting musculocutaneous nerve of "Chutse" acupoint group, cutting musculoutaneous nerve group, control group. Results showed that there is no role in laser acupuncture at "Chutse" acupoint for reducing myocardial injury and size of AMI after cutting musculocutaneous nerve of "Chutse" acupoint. It is illustrated that the musculocutaneous nerve might play an important role in the relationship between "Chutse" acupoint and heart.
