title: Effect of the water-soluble and non-dialyzable fraction isolated from Senso (Chan Su) on lymphocyte proliferation and natural killer activity in C3H mice.
abstract: We found lymphocyte proliferating substances in the water-soluble and non-dialyzable fraction prepared from the crude drug Senso (Chan Su). The effect of this fraction was increased by affinity chromatography using the concanavalin A-agarose. By analyzing the fraction using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and lectin blotting, we estimated that one of the active substances of this fraction is a glycoprotein that has about 13 kDa of molecular weight and D-mannose within the molecule. The purified fraction increased the IL-2 and the IL-12 level in the supernatant of spleen cell culture, and increased the natural killer activity of spleen lymphocyte in C3H/HeN mice. These results show that Senso contains immunopotentiating substances that may serve as an immunomodulator in an organism.
