These experiments were conducted to investigate the effects of Cervi cornu extract on lymphocyte blastogenesis in spleen, thymus, lymph node, born marrow cells of Balb/c mouse, haemagglutination reaction against sheep red blood cell (SRBC), plaque forming cell (PFC) assay against SRBC and IL-2 production. Lymphocyte blastogenesis was determined by $[^3H]-thymidine$ incorporation. According to the lymphcoyte blastogenesis test on the immune cell. Ceriv cornu extrat was showed a potent mitogenic activity on the spleen and lymph node cells, but had mild mitogenic activity on the thymus and born marrow cells. Mitogenic active component of Crevi cornu extract was identified to be materials where molecular weights are higher than 5,000 by membrane filteration method. Cervi cornu extrat was shown to increase mitogenic effect on the lipopolysaccharide (LPS)-stimulated spleen cells significantly, but decrease mitogenic effect on the Con A stimulated spleen cell at the concentration 0.3%, 1% and 3%. Ceriv cornu extract didn't show to be haemagglutination reaction and showed to inhibit the Con A-induced haemagglutination reaction against SREC. Result of SRBC-PEC test. Ceriv cornu extract significantly increase the number of PEC at the concentration of 0.1% and 1%. When IL-2 or IL-4 production was determined by proliferation of CTLL-2 cells. Ceriv cornu extract was not shown to stimulate the production of IL-2. From the above results, it is shown that Ceriv cornu extract increased antibody production by B cells, but nor IL-2 production by helper T cells.
