RESUMEN
@#Objective To observe the effects of rehabilitation on the quality of life and capacity of aerobic exercise in patients after coronary artery bypass graft. Methods 58 patients after coronary artery bypass graft were divided into rehabilitation group (n=31) and control group (n=27). Patients in the control group received routine drug treatment out of hospital, while the rehabilitation group was guided regularly for rehabilitation. All patients were surveyed with the MOS item short form health survey (SF-36) and 6 min walking test on the 15th and the 90th day after operation. Results Compared with the control group，the scores of all the items of SF-36 in rehabilitation group improved (P<0.01) except in body pain. The result of 6MWT was also higher in rehabilitation group than in controls(P<0.01). Conclusion Rehabilitation can improve capacity of aerobic exercise and the quality of life of patients after coronary artery bypass grafting.
RESUMEN
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
