ABSTRACT
A serous membrane covering the liver and the hepatic parenchyma, consists of hepatocytes, arteries, veins, hepatic sinusoids and biliary ductuli. There are erythrocytes, thrombocytes, melanin particles and Kupffer cell in the hepatic sinusoids and the blood vessels. The gall bladder wall consists of a mucous layer a muscle layer and a serous layer. The bottom of the epithelium abounds with round or oval secretory. In liver, immunohistochemistry results show that AQP1 have intense reaction in hepatic lobule, Kupffer cells (Macrophagocytus stellatus), hepatocytes, portal tract, blood islands, vein and artery, but almost no reaction of AQP2 was detected. In gallbladder, mucous epithelium, endothelial cells from vein and artery all have strong AQP1 expression, AQP2 showed minor diffused positive reaction in gallbladder, which suggesting that AQP1 may have the main role in the absorption and transportation of fluid in hepatobiliary system of Qinghai Lizard.
RESUMEN
Una membrana serosa cubre el hígado y el parénquima hepático el cual está formado por hepatocitos, arterias, venas, sinusoides hepáticos y conductos biliares. Se encuentran eritrocitos, trombocitos, partículas de melanina y células de Kupffer en los sinusoides hepáticos y en los vasos sanguíneos. La pared de la vesícula biliar presenta tres capas mucosa, muscular y serosa. En el hígado, la inmunohistoquímica mostró que AQP1 tiene una reacción intensa en el lóbulo hepático, células de Kupffer, hepatocitos, tracto portal e islotes sanguíneos. En venas y arterias, no se detectó reacción alguna de AQP2. En la vesícula biliar, el epitelio mucoso, las células endoteliales venosas y arteriales tuvieron una importante expresión de AQP1, sin embargo, AQP2 mostró una reacción positiva difusa menor, lo que sugiere que la AQP1 podría tener una función principal en la absorción y transporte de líquido en el sistema hepatobiliar del Lagarto Qinghai.
