  13. Abstract : the anti - inflammatory effect of n - butanol extract of xanthocerassorbifolia bunge ( bex ) was studied in this paper. the ear edema resulted from dimethyl benzene, paw edema induced by carrageenin, the increase of vascular permeability caused by acetic acid, the chemotaxis of wbc induced by cmc and the weight of cotton granuloma in mice and hind paw edema induced by fresh egg white in rats were inhibited significantly by ig bex daily for 7 days, respectively. the carrageenin - induced paw edema was also inhibited markedly in adrenal - ectomiced mice. no changes in weight of adrenal and the concentration of vitamin c were observed, indicating that the anti - inflammatory effect of bex was not related to pituitary - adrenal system
