AIM: To study the effect of rubidatum (Rub) on immune function in normal mice. METHODS: Serum lysozyme concentration (SLC) was measured using micrococcus lysodiekticus as a substrate. Delayed type hypersensitivity (DTH) was determined by measuring the thickness of the right hind footpad 24 h after the injection of 1 x 10(8) washed sRBC (50 microL 10% sRBC). Serum hemolysin concentration was determined by OD measuring at A540 after the serum was treated with 2-mercaptoethanol. Phagocytic function of peripheral leukocyte (Leu) were determined by the incorporated radioactivity of [3H]TdR. The hemolytic activity of plaque forming cell (PFC) was determined by measuring the lymphocytemediated hemolysis of sheep red blood cell in vitro. T- and B-lymphocyte transformation (TLT and BLT) were induced by phytohemagglutinin (PHA) and lipopolysacharide (LPS) respectively and measured by the incorporation of [3H]TdR. RESULTS: Rub 125, 500, 2000 p.o. to BALB/c (or NIH) mice decreased the SLC; inhibited the phagocytosing functions of peripheral leukocytes; diminished the hemolytic activity of PFC; decreased the HC50; inhibited the DTH reaction; and showed inhibitory effects on TLT and BLT. CONCLUSION: Rub has immunosuppressive effects on immune system in mice by affecting M phi, T, and B lymphocyte, which suggests that Rub has inhibitory effects on both nonspecific and specific immune function.
