[Effect of niupo zhibao pellet on transforming growth factor-beta1 and its receptor's expression in endotoxic shock rats with lung injury].

ABSTRACT To observe the influence of Niupo Zhibao pellet (NZP) on transforming growth factor-beta1 (TGF-beta1) and its receptor's expression.
Endotoxic shock model was established by intravenous injection of lipopolysaccharide (LPS) 1.5 mg/kg and intraperitoneal injection of D-galactosamine 100 mg/kg, and intervened by NZP, TGF-beta1 and its receptor's expression in lung tissue were detected by immunohistochemical method.
NZP could enhance the TGF-beta1 and its receptor's expression in endotoxic shock lung tissue, and reduce the injury of lung.
The mechanism of NZP in reducing endotoxic shock lung injury is possibly related with its effect in enhancing the TGF-beta1 and its receptor's expression in lung tissue.
