RESUMO
Objective: To explore the effect of Wamingfen on eosinophil apoptosis and oxygen free radicals and to study the influence of hydrocortisone on airway inflammation in asthma guinea pigs. Methods: Guinea pig models of asthma were induced by egg albumin. The effect of Wamingfen on plasma malonyl dialdehyde (MDA), blood glutathione peroxidase (GSH-Px),erythrocytic superoxide dismutase (SOD) activity , serum hydrocortisone level and the percentage of EOS apoptosis in bronchial-alveolar lavage fluid (BALF) were observed. Results: Wamingfen can apparently increase the content of GSH-Px ,SOD and serum hydrocortisone, promote the apoptosis of EOS and reduce the amount of MDA. Conclusion: Wamingfen can effectively increase serum hydrocortisone content, remove the oxygen free radical, promote eosinophil apoptosis and reduce the hyper-reactivity in the inflammatory airway.
RESUMO
The concentration of the cyclic nucleotides and its relation with the E-RFC were determined by using ginseng rhizome saponin in human peripharal leukocytes.Result were compared with the ckange of the E-RFC by using cAMP.cGMP and theophylline. Experiments proved that girseng rhizome saponin mainly affected the lymphocytes and significantly increased the concentration of cAMP and cGMP,especially,the cAMP. Lymphocytes were incubated with ginseng rhizome saponin to form Et-RFC. It is different where lymphocytes were incubated in diffierent times. cAMP and theophylline reduced the Ea-RFC and Et-RFC, cGMP increased the Ea— RFC,but no effect to the Et-RFC. Ginseng rhizome or root saponin could promote the Ea-RFC,but inhibited the Et-RFC. It is consistent with the effect of both cAMP and cGMP. Experiments showed that ginseng rhizome saponin increased the concentration of cAMP and cGMP in human lyphocytes followed by that of E-RFC.It was suggested that the change of cyclic nucleotides in lymphocytes may be a mechanism of adjusting the immunity on cell level.
