Relationship between TGF ?1 expression and apoptosis in hepatocytes during acute hemorrhagic necrotic pancreatitis / 中国病理生理杂志

ABSTRACT

AIM: To observe the expression of TGF ?1 in hepatocytes during acute hemorrhagic and necrotic pancreatitis (AHNP) and to study the relationship between TGF ?1 and apoptosis in hepatocytes. METHODS: AHNP was induced in 40 rats weighting 260-280 g by intraductal administration of 5% sodium taurocholate. The pathologic morphologic changes of liver and pancreas were observed under light microscope. The hepatocyte apoptosis was examined through TdT (terminal deoxynucleotidyl transferase) mediated dUTP nick end labeling (TUNEL) and the expression of TGF ?1 in hepatocytes was analyzed through immunohistochemistry. RESULTS: The liver injuries were found at 3 h after the inducement. These changes were aggravated with the development of the disease. The apoptotic hepatocytes were found after 3 h (P
