pathogenesis
stimulant(cytokines,toxins)-stimulatn f hepatic stelate cels-stelate cels transform into myofibroblast lke cels-dpostn f colagen in space f disse-new vascular chanel form in septa-continuous dpostn f colagen leads to los f fenestratn in sinusoid endothelial cels-exchange f solute bet plasma n hepatocyteis impaird-toxic concn f fibroblast lead to constrictn f sinusoid vascular channels-thruout damage n fibrosis rmaining hepatocyte r stimulatd to form fibrotic nodule.
