Effects of Astragali radix extract (AG) on the humoral immunotoxic responses of zinc chloride (Zn) were studied in ICR mice. Mice were divided into 4 groups (10mice/group), and Zn was given to the mice, 1hr after I.p. injection with 0.5g/kg of AG, by I.p. injection daily for 10 days at a dose of 25mg/kg. Mice were immunized and challenged with sheep red blood cells (SRBC). Zn treatment increased the relative weight of spleen compared with those in controls, but decreased the hemagglutination (HA) titer, 2- mercaptoethanol-resistant HA (MER-HA) titer and splenic plaque forming cells (PFC). AG treatment significantly increased the relative weight of spleen, HA titer and PFC compared with those in controls. Combination of Zn and AG significantly increased the relative weight of spleen compared with those in controls,but decreased the HA titer, MER-HA titer and PFC. The relative weight of spleen was significantly increased in the Zn and AG combination group than those in Zn alone treatment group. But the HA titer,MER-HA titer and PFC were slightly increased in the group of combination. These results suggest that AG might slightly restore humoral immune responses lowered by an excess of zinc.
