Different behavioral models of elevated plus maze, open field, light/dark, hole-board and pentobarbital-induced sleep were used to assess anxiety-like behavior. Biochemical parameters including monoamine oxidase-A(MAO-A) activity, lipid peroxidation, % inhibition of superoxide anion and glutathione peroxidase activity were measured. Histologic studies were also examined.Results: Mice receiving various doses of A. graveolens(125, 250 and 500 mg/kg)showed an alleviation of anxiety-like behavior as evidenced by the battery of behavioral tests. Likewise, A. graveolens treatment was found to significantly decrease MAO-A activity, lipid peroxidation as well as cause a significant increase of % inhibition of superoxide anion and glutathione peroxidase activity in both cortex and striatum. The total number of survival neurons found in the frontal cortex and striatum was significantly higher than that of the vehicle-treated group.Conclusions: Taken together, we showed that A. graveolens improve the behavioral changes which might be related to the inhibition of free radicals and modulation of MAOA activity resulting in an increased number of survival neurons. Our findings suggest the therapeutic potential of A. graveolens in the treatment of anxiety.展开更多

NSCs were isolated from the striatum of SD rat embryo were cultured in the medium containing aqueous extract from Apium graveolens L（AAG）.and/or the serum derived from mice treated with Apium graveolens L （SAG）. The results show that AAG promoted the survival and growth of NSCs in low concentration. Apium graveolens L. leaves aqueous extract promoted the proliferation of NSCs in relatively high concentration. SAG significantly accelerated the differentiation of NSCs.展开更多
