RESULTS: Symptoms of all the patients undergoing bone marrow stem cell transplantation were alleviate to a certain extent. Edema and feeling of ponderosity were moderated evidently. Cicatricle was softened. The difference of affected and unaffected sides its upper limb dropsy patients was (9.2±1.4) cm before treatment, and (3.5±0.9) cm after 3 months of treatment. The difference of affected and unaffected sides in lower limb dropsy patients was (8.2±1.3) cm before treatment, and (3.7±0.6) cm after 3 months of treatment.
