Background: Solanum nigrum L. has been used in traditional Chinese medicine because of its diuretic andantipyretic effects. The present research concerned effects of crude polysaccharides isolated from Solanum nigrumL. on erythrocyte membranes of tumor-bearing S180 and H22 in mice. Materials and
Methods: Fluorescencelabeledred blood cell membranes were used with DPH fluorescence spectrophotometry to examine erythrocytemembrane fluidity, and colorimetry to determine degree of erythrocyte surface membrane blocking. Extentof reaction by tumor-bearing mice with the enzyme erythrocyte membrane bubble shadow detection of redcell membrane variation in the degree of closure before and after administration.
Results: Solanum nigrumpolysaccharide could significantly improve the S180 and H22 tumor-bearing mice erythrocyte membrane fluidity,compared with the control group, the difference was significant (p<0.01), SNL can significantly improve the redblood cell membrane and then S180 tumor-bearing mice sealing ability, compared with the negative control group,the difference was significant(p<0.05, p<0.01). H22 tumor-bearing mice can increase red cell membrane and thensealing ability, the difference was significant (p<0.05). Solanum nigrum polysaccharide degree of fluidity andblocking two transplanted tumors in mice restored the ability to raise the red cell membrane has a significanteffect.
Conclusions: Solanum nigrum L.-type mice transplanted tumor can affect the red blood cell membranefluidity and re-closed, through the red cell membrane of red blood cells to enhance the immune function of thepossibility of erythrocyte immunity against tumor formation garland provide experimental basis.
