ABSTRACT
@#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.
ABSTRACT
Objective To observe the effects of rehabilitation intervention on the quality of life (QOL) of patients after coronary artery bypass grafting. Methods Fifty-eight hospital patients in need of coronary artery by-pass grafting (CABG) were randomly assigned to a cardiac rehabilitation group ( rehab ; n = 31 ) or a routine care group (control; n = 27 ). In the rehab group, patients received progressively increasing movement and appropriate psychological intervention. Changes in the medical outcome study short form (SF-36) scores and 6 min walk dis-tances (6MWDs)as well as the length of post-operative stays in hospital were observed in both groups. Results Compared with the control group, patients in the rehab group scored significantly higher on the SF-36. Their physical functioning, general health, vitality, role-emotion and mental health scores improved significantly, their final 6MWDs were longer, and they had significantly shorter average hospital stays after the operation. Conclusions Rehabilita-tion training can improve QOL for patients after coronary artery bypass grafting.
ABSTRACT
The effects of formaldehyde fixation on the binding capacity of opiate receptors were studied with radioreceptorassay and in vitro receptor autoradiography. Incubation with 1% paraformaldehyde for 30 minutes or 12 hours has no significant influence on the binding capacity of opiate receptors of rat brain P_2 membranes, and incubation with 2% or 4% paraformaldehyde for 30 minutes also did not alter the binding capacity of opiate receptors significantly, but 12 hour incubation with 2% or 4% paraformaldehyde would change the binding capacity significantly. The saturation curve of [~3H]-etorphine binding with opiate receptors in formaldehyde fixed brain tissue sections coincided with that of unfixed brain tissue sections. The opiate receptors were successfully demonstrated with in vitro receptor autoradiography in 1% paraformaldehyde fixed spinal cord sections. These results indicate that formaldehyde fixed tissue are applicable to in vitro receptor autoradiography.
