Study on Effects of Two Kinds of Cactus Polysaccharides on The Protein Contents and The Lipid Fluidity of Erythrocyte Membrane in S180 Mice
To study the effects of two kinds of cactus polysaccharides on band 3 protein content, cross-linking protein content, and the lipid fluidity of erythrocyte membrane in S180 mice. Membrane protein content is analyzed by SDS-PAGE, and lipid fluidity of the membrane is measured by the Skinitzky method. The two kinds of cactus polysaccharide increase the content of band 3 protein, decrease the content of cross-linking protein, and increase lipid fluidity. For medical cactus polysaccharide, the effect of the medium dosage group is significant (P＜0.01); but for edible cactus polysaccharide, it is the high dosage group that has a significant effect (P＜0.01). By improving the functioning of erythrocyte membrane of tumor-bearing mice, the two kinds of cactus polysaccharides enhance their immunological function, and this may be one of the anti-tumor mechanisms of cactus polysaccharides.
