[Effect of plant polysaccharides on phosphatidylinositol turnover of sarcoma S180 cell membranes].

Mice sarcoma S180 cell membranes, [r-32 P]ATP and plant polysaccharides (PPS, ASPS, TF and lentinan) were incubated together for 5 min at 30 degrees C. Phosphatidylinositides were isolated and subjected to scintillation fluid counting. The results showed that PPS and ASPS, especially the latter, could inhibit the phosphatidylinositol turnover obviously, while TF and lentinan had no such effect.
