METHODS Influences of RCE on ultrastructure were observed in tumor cells under the transmit electronic microscope and the influences on growth of different cells were also detected by MTT cyto-dyed. RESULTS RCE could induce tumor cells apoptosis and make mucleiu small, cytoplasm increase, membrane lytic and absorbance of MTT decline, but it could increase absorbance of MTT in lymphocyte. CONCLUSION RCE could inhibit growth of tumor and enhance lymphocyte tranformation.展开更多
