RESUMEN
Aim The effect of extracts of astralus(EA) on learning, memory and immune function of CTX treated mice was observed.Methods The step-down test was adopted to investigate learning and memory in mice; the method of enveloping CRBC was adopted to explore the function of macrophage in abdominal cavity; 3H-TdR marking method was used to observe the prolifernation of T lymphocytes and the method of ELISA was applied to measure the concentration of IFN-? in blood. Results EA (25 mg?kg-1, 50 mg?kg-1,ig, 21 d ) could boost learning and memory , enhance the phagocytic activity of monocytes and the proliferation of T lymphocytes of CTX treated mice, and increase the concentration of IFN-? in blood of CTX treated mice. Conclusion EA not only promote learning and memory, but regulate immune function.
