An effective strategy for inhibition of cirrhosis
September 25, 2008In China, the incidence of liver cirrhosis is still high, although new therapeutic approaches have recently been proposed, there is no established therapy for liver fibrosis, and Authors investigated the prevention effects of Chinese Medicine Qianggan-Rongxian Soup on liver fibrosis induced by DMN in rat. Chinese Medicin Qianggan-Rongxian decoction can inhibit hepatic fibrosis resulted from chronic liver injure, retard the development of cirrhosis, and notably ameliorate the liver function. It may be a safe and effective therapeutic drug for patients with fibrosis.
A research article to be published on 14 June 2008, in the World Journal of Gastroenterology addresses this question. The research team led by Chun-Hui Li from affiliated Hospital of Chengde Medicine College studied the inhibitory effect of Huangqi Zhechong decoction on liver fibrosis in rat.
Qianggan-Rongxian decoction, especially the medium-dose administration could decrease the area-density percentage of collagen fibrosis. HA, LN, and type IV collagen are good serum markers of hepatic fibrosis. In this study, the serum contents of these 3 markers in the model group were much higher than those of the controls. And the Qianggan-Rongxian decoction groups had significantly low HA, LN, and type IV collagen levels in serum than those in the controls, ALT and AST are indexes to describe liver functions. Most part of ALT is presented in the cytoplasm of liver cell, discharged in blood when degeneration, hyper permeability and necrosis of liver cells occur. So the increase of ALT level in serum reflects the degree of liver cell injury. Our study showed that the Qianggan-Rongxian decoction could decrease serum levels of ALT and AST in rats with hepatic injury caused by DMN. It indicates that Qianggan-Rongxian decoction may work through protecting the liver cells, which indicated that Qianggan-Rongxian decoction could successfully prevent hepatic fibrosis.
The mechanism of DMN-induced liver fibrosis has been shown to be associated with immune function, which is similar to the mechanism of human liver fibrosis. Thus, DMN-induced rat liver fibrosis may be a useful model for determination of liver fibrosis during drug screenin. The mechanism of the Qianggan-Rongxian decoction may need further research.
This study may provide a safe and effective strategy for inhibition of cirrhosis in clinic use.

Several studies have shown that lipid peroxidation stimulates collagen production in fibroblasts and hepatic stellate cells (HSC), and plays an important role in the development of liver fibrosis.
The use of stem cells in regenerative medicine may also be detrimental for health
The use of stem cells in regenerative medicine is not always beneficial for human health, it may even be harmful according to a work done by the University of Granada and University of León. Scientists have demonstrated that transplantation of human mononuclear cells isolated from umbilical cord blood exerted a deleterious effect in rats with liver cirrhosis.

A combination of bioengineering and medical research at the University of California, San Diego has led to a new discovery that could pave the way for more effective treatments for liver disease.
A potential therapeutic agent for hepatic fibrosis
Accumulating evidence suggests that connective tissue growth factor (CCN2) plays a central role in fibrotic conditions in many organ systems.

A major clinical challenge is to find the best method to evaluate and to manage the increasing numbers of patients with chronic liver disease. Liver biopsy, due to its risks and limitations, is no longer considered mandatory as the first-line indicator of liver injury, and several markers have been developed as non-invasive alternatives.

Fat Storing Cells and Liver Fibrosis (Falk Symposium) by Calgero Surrenti (Editor), A. Casini (Editor), S. Milani (Editor), M. Pinzani (Editor) The field of liver fibrosis has become of great interest in the last decade. Although knowledge of the mechanisms leading to liver fibrogenesis and fibrosis has dramatically improved during the last 3--4 years, we are still at the edge of the truth. Several reports have stressed the role of nonparenchymal cells as the main producers of hepatic extra-cellular matrix. In particular, fat-storing cells (also known as Ito cells or lipocytes or perisinusoidal stellate cells) have been recently shown to play a major role in this process. The Falk Symposium No. 71 was dedicated to basic science and clinical aspects of fat storing cells and liver fibrosis, and brought together an international group of investigators to highlight unsolved problems and to discuss common strategies of... | |

Description: Activins are a closely related subgroup within the TGF@b superfamily of growth and differentiation factors. They consist of two disulfide-linked @b subunits. Four mammalian activin @b subunits termed @b"A, @b"B, @b"C, and @b"E, respectively, have been identified. Activin A, the homodimer of two @b"A subunits, has important regulatory functions in reproductive biology, embryonic development, inflammation, and tissue repair. Several intra- and extracellular antagonists, including the... |

Molecular and Cell Biology of Liver Fibrogenesis (Falk Symposium) by A.M. Gressner (Editor), G. Ramadori (Editor) This volume, the proceedings of the International Falk Symposium held in Marburg, Germany, in January 1992, summarizes the most recent advances in the study of cellular and molecular mechanisms of fibrosis provided by contributions from the leading scientists in this field. It updates our knowledge on the basic components of fibrosis, on the cellularorigin and degradation of matrix components, on peptide and non-peptide mediators, cellular cooperation and other mechanisms of fibrogenesis, on the role of the extracellular matrix as modulator of fibrogenesis, and on some aspects of antifibrotic trials and biochemical monitoring of the development of fibrosis. Since liver fibrogenesis has, to a certain extent, attained the status of a model for fibrotic tissue reactions that... | |
