Ninjin-to augmented the natural killer (NK) cell activity by a single intraperitoneal administration at doses of either 50, 100 or 200 mg/kg. Sho-saiko-to also augmented this activity at a dose of 100 mg/kg, but suppressed it at a dose of 200 mg/kg. An oral administration of Sho-saiko-to and Ninjin-to once a day at a dose of 250 mg/kg augmented the NK cell activity 7 and 20 days later, respectively. The effect of the remaining two Kampohozais was negligible. Four Kampohozais each exhibited a stronger mitogenic activity on B cell-rich population than on T cell-rich population, suggesting that these Kampohozais act as B cell mitogens. Treatment of mice with Sho-saiko-to by oral administration once a day for 13 days at a dose of 250 mg/kg increased the number of splenic antibody-producing cells against sheep erythrocytes, accompanied with an increase in both serum hemagglutinin and hemolysin titers.}, pages = {161--167}, title = {Effects of Kampohozais (Sho-saiko-to, Ninjin-to, Hochu-ekki-to and Juzen-taiho-to) on Immune Responses in Mice}, volume = {39}, year = {1991} }
