Extracts of Chinese herbs were administered with antitumor agent, cyclophosphamide (CY), and their effects on macrophages and lymphocytes were studied. Number of peritoneal macrophages significantly decreased and their chemotactic activity was suppressed by treatment with CY. Blastogenic responsiveness to Concanavalin A and NK cell activity of spleen lymphocytes were suppressed significantly in CY-treated mice. Extracts of Lithospermi radix, Astragali radix and Glycyrrhizae radix showed protective effects on immunosuppressive mice. The number of macrophages, chemotactic activity of macrophages and blastogenic response of lymphocytes were recovered to the same or more than that of normal levels. An extract of Ginseng radix showed protective effects on the number and functions of macrophages by treatment with CY but did not show any effects on the lymphocytic blastogenesis. On the contrary it showed a strong inhibitory effect on the NK cell activity. These results suggest that Chinese herbs could modulate cellular immune response, especially in the activation of macrophages and splenic lymphocytes.
