Abstract
AIM:To investigate the role of all-trans retinoic acid (ATRA)in the early stage of alcoholic liver fibrosis in rats, by observing itseffect on the expression of transforming growth factor b1(TGF-b1), connective tissue growthfactor (CTGF) and pro alpha 1 (Ⅰ)collagen (Col1a1).
METHODS:Twenty-four rats were randomly and averagely dividedinto three groups, named J, A, and N. The rats in group J was given themixture of ethanol and corn oil, and those in group A were added ATRA[0.15 mg/(kg.d)] after treatment with the same mixture for 8 wk. Theanimals in group N served as the controls, treating with the same amountof normal saline plus corn oil. All the mixtures were givenintragastrically. All the animals were killed after 16 weeks. Thehistological changes of liver tissues were observed under light andelectron microscope ......
