OBJECTIVE: To assess the efficacy of "method of activating blood circulation and removing stasis (ABCRS)" in treating polycythemia vera. METHODS: 28 cases of polycythemia vera were treated with ABCRS and observed with bone marrow colonies. RESULTS: 15 casses were responsibe, of them 4 cases reached clinical remission, 11 cases were improved. Both bone marrow colonies of colony forming unit-erythroid dependent of erythropoietin (EPO + CFU-E) and colonies of CFU-E independent of EPO. (EPO-CFU-E) from these cases decreased significantly, especially the latter. ABCRS mainly suppressed the proliferation and differentiation of EPO-CFU-E. In addition, bone marrow colonies of colony formng unit-fibroblastoids (CFU-F) from these cases also changed obviously. CONCLUSION: ABCRS is effective in treating polycythemia vera.
