ABSTRACT
Objective To approach the effects of decoction changed from Didangtang and Xiaoxianxiongtang Modified Formula on mucoprotein in stratum medium and the III-type collagen level of serum in experimental rats with fibrosis disease in lung interstitial tissue. Methods 40 male Wistar rats were randomly divided into 4 groups, that is pseudo-operation group, model control group, traditional Chinese drug group (TCD) and western medicine group (WM). Every group has 10 rats. Acid hydroc bleocin was dripped disposably into trachea of every group rats except pseudo-operation group, and Sodium Chloride with same volume as Acid hydroc bleocin was dripped disposably into trachea of pseudo-operation group. 24 hours after operation, the rats of TCD was lavaged with Decoction changed from Didangtang and Xiaoxianxiongtang Modified Formula, and the rats of WM was lavaged with Prednisone physiological saline solution. The rats of pseudo-operation group and model control group was lavaged with Sodium Chloride of same volume as TCD and WM. 28 days after operation, the rats was executed. And contents of mucoprotein in stratum medium of and the III-type collagen serum was detected. Results Didangtang and Xiaoxianxiongtang Modified Formula could decrease contents of mucoprotein in stratum medium of and the III-type collagen in serum of experimental rats, and extenuate fibro-accrementition in lung interstitial tissue. Conclusion Didangtang and Xiaoxianxiongtang Modified Formula has the function of treating fibrosis disease in lung interstitial tissue probably by decreasing contents of extracellular matrix in experimental rats with fibrosis disease in lung interstitial tissue.
