Abstract:
Objective To observe the effects of ultrasound medium frequency electrotherapy on pain and content of enkephalins. Methods The pain threshold of the rat was measured before and after the application of ultrasound medium frequency electrotherapy. The content of met enhephalin(MEK) and leu enkephalin(LEK) in the glandula hypophysis and hypothalamus was also measured. A linear regression analysis based on the pain threshold and the content of enkaphalin was conducted to reveal the pain relieving mechanism of the ultrasound medium frequency electrotherapy. Results The level of MEK and LEK in the glandula hypophysis and hypothalamus was significantly increased after a single use action ultrasound medium frequency electrotherapy as compared with that before the treatment ( P
