| Abstract | Marsdeniae tenacissimae extract (MTE) has been used as an adjuvant medicine for cancer therapy for a long time. Although massive studies demonstrated its considerable anti-cancer effect, there is no research on its influence on erythrocytes, which are firstly interacted with MTE in the circulation. To investigate the influence of MTE on erythrocytes, we used a flow cytometer to detect the MTE-treated alternations of morphology, calcium concentration, and reactive oxygen species (ROS) level in erythrocytes. We used hemolysis under different osmotic solutions to evaluate the fragility of erythrocytes. Data showed that MTE treatment dose-dependently increased the ratio of erythrocyte fragmentation (P<0.001) and shrinking, and elevated the forward scatter (FSC) value (P<0.001) and calcium accumulation (P<0.001). MTE induced ROS production of erythrocytes under the high glucose condition (P<0.01) and consequently caused a rise in fragility (P<0.05). These results suggest that MTE induces cytotoxicity and aging in erythrocytes in a dose-dependent manner, and presents the possibility of impairment on cancer patientsâ circulating erythrocytes when MTE is used as an anti-cancer adjuvant medicine. |
