| pubmed-article:19220679 | pubmed:abstractText | Pig serum-induced rat liver fibrosis is a model of liver fibrosis in the absence of obvious hepatocyte injury. Penoxifylline (PTX), a xanthine derivative, which is a well-known suppressor of tumor necrosis factor-alpha (TNF-alpha) production from inflammatory cells, has also been shown to inhibit the growth of hepatic stellate cells and to inhibit collagen synthesis in these cells in vitro. We investigated the effect of PTX on pig serum-induced liver fibrosis in vivo, and assessed the mechanisms of prevention of fibrogenesis by this drug. | lld:pubmed |
