["Through the establishment of mouse' ovalbumin- sensitized asthmatic model and the observation of the 8-Isoprostane of plasm, to evaluate the therapeutic effects of arsenolite on asthmatic mice.", 'Forty-two healthy Kunming male mice were randomly divided into control group and experience groups, the latter were treated with dexamethasone, arsenolite. Lung function were tested, 8-isoprostane of plasm and WBC of BALF were measured.', 'Lung function improved after treating with dexamethasone or arsenolite. The WBC of asthmatic mice were significantly higher than those in control group, and decreased after treating with dexamethasone or arsenolite; 8-Isoprostane of plasm in asthmatic mice was higher than that of control group, and decreased after treating with dexamethasone or arsenolite.'] Do [ Role of arsenolite on 8-isoprostane of asthmatic mice plasm ]?
