Dose-dependent responses indicated by the increase of leukocyte, peritoneal exudate cell and weights of immunorgans revealed the improvement of immunity. In the effect of macrophage on phagocytes, there were not substantial differences in the phagocytic and corrected phagocytic index. The administered group being compared with the controlled group, there were no significant changes in SGOT, S-GPT, alaline phosphatase, total protein, albumin, globulin, cholesterol, triglyceride, blood urea nitrogen and glucose. Key words: dose-dependent responses, peritoneal exudate cell, phagocytic idex, corrected phagocytic index.
