Twenty patients with chronic lymphedema had been treated by microwave heating. T-lympocyte subpopulation and HLA-DR phenotype of peripheral blood in patientswith lymphedema were examined by using dual colour flow cytometry before and after treatment. We found that CD4 (T helpe/inducer) in chronic lymphedema decreased significantly (Plt;0.01), HLA-DR increased significantly (P lt;0.05). After the microwave treatment, the CD4, CD4/CD8 ratio increased significantly; HLA-DR, HLA-DR+CD+8 lymphocyte reduced. It was clear that microwave could regulate the immunological disorder of lymphedema patients.
The rectus femoris muscles of rabbits were used as muscle model. The electrical stimulation which resembled the normal motor-unit activity was used to observe its effects on free transferred muscle. After three months, the moist muscle weight (MW), its maximum cross-section area, its contractility and its histochemical characteristics were examined. The results showed that the function and morphology of the muscles were well preserved. These findings might encourage its clinical application.
