This study was carried out to investigate the dose dependent antifibrotic effects of polysaccharide from mycelium of Ganoderma lucidum. The experimental hepatic cirrhosis was induced by bile duct ligation/scission (BDL/S) in rats. BDL/S rats in each group were dosed 0.5 mg, 2.0 mg, 5.0 mg or 10.O mg/rat/day orally for 4 weeks after the operation. Antifibrotic effects were evaluated by serum biochemical values, hydroxyproline contents, and light microscopical histology. The results obtained were as follows: 1) Hydroxyproline contents in liver of 5.0 and 10.0mg polysaccharide-treated BDL/S rats were significantly reduced 2) In serum test, ALT, AST, ALP values in polysaccharide from Ganoderma lucidum-treated group were lower than BDL/S control group 3) The hepatic damage such as hepatocellular necrosis, inflammation, bile duct proliferation and fibrosis was less severe in the livers of 2.0 mg and 5.0 mg polysaccharide-treated rats. These results suggest that polysaccharide from mycelium of Ganoderma lucidum to be a promising agent for the inhibition of hepatic cirrhosis.

This study was carried out to investigate the antifibrotic effects of polysaccharides extracted from Garnoderma lucidum. The biliary cirrhosis was induced by bile duct ligation/scission (BDL/S) in rats. BDL/S rats were dosed 5 mg/rat/day orally for 4 weeks after the operation. Antifibrotic effects were evaluated by serum biochemical values, serum procollagen type III peptide (PIIINP) levels, liver hydroxyproline contents, and light microscopical histology. The results obtained were as follows; 1) PIIINP levels in sera of treated BDL/S group were lowered to 50% of those of untreated BDL/S group. 2) Hydroxyproline contents in the liver of treated BDL/S group were also reduced to 83% of those of untreated BDL/S rats. 3) The hepatic damage such as hepatocellular necrosis, inflammation, bile duct proliferation and fibrosis was less severe in the livers of treated rats. These results suggest polysaccharides extracted from Garnoderma lucidum to be a promising agent for the inhibition of hepatic cirrhosis(fibrosis).

Hepatic cirrhosis is an important feature of chronic liver disease. Liver cirrhosis is characterized by hyperaccumulation of fibrous tissue components and is commonly observed in latter or terminal states of chronic hepatic disease. The antifibrotic effects on liver cirrhosis by oriental herbs extraction material were examined in bile duct ligated rats. Oriental herbs extraction (0.99 mg/kg rat weight/day) was administrated to cirrohotic rats for 4 weeks. Liver collagen content of bile duct ligated rats was significantly increased. And liver histology showed collagen fiber deposition was increased as well as the normal architecture was lost with large zone of necrosis being observed. Herbs extraction administrated rats showed significantly decreased liver collagen content, accumulation of collagen fiber in histological analysis, and biochemical markers of hepatic diseases. Those results demonstrate the usefulness of herbs extraction materials as an antifibrotic agent for liver cirrhosis.

Antifibrotic drugs could be delayed or inhibited massive collagen deposition in liver tissue or inhibited collagen synthesis. we investigated antifibrotic effects by several herbs(Schisnadra chinensis, Ganoderma japonicum, Sedum sarmentosum, Alisma canaliculatum, Plantago asiatica) extract with observations of collagen accumulation in liver tissue and collagen synthesis in sera. Rats were used for experimental animal that were devided 3 groups(sham control, BDL/S, BDL/S-ER). Rats were operated for inducing liver fibrosis(cirrhosis) by bile duct obstruction. Several herbs were prepared by water extraction and were applicated p. o. $3ml/day$ during 4 weeks. After observation period, rats were sacrificed and liver tissue and sera were collected. In result, the mortality of rats was 35% in BDL/S group and 20% in BDL/S-ER The color of bile juice in BDL/S-ER was bright yellow and murky yellow in BDL/S group. The significantly lower weight of liver($16.21g{\pm}5.3,\;20.58{\pm}2.4$) and spleen($1.96g{\pm}0.96,\;3.93{\pm}0.21$) were shown in BDL/S-ER than that of BDL/S(p<0.05) group. The value of collagen in liver tissue(25.7%) in BDL/S-ER was observed significantly lower than that of BDL/S group (Tab. 2). AST. ALT, ALP, t-bilirubin, BUN levels were low in BDL/S-ER as compared with those of BDL/S group, but the significance was not proven. The trichrome stained liver tissue in BDL/S-ER group was observed mild bile duct proliferation and fibrosis compared with BDL/S group. In conclusion, natural products inhibited new collagen synthesis and delayed massive collagen deposition in liver tissue, so that they have noticeable antifibrotic effects in experimental liver fibrosis(cirrhosis).

Liver cirrhosis is characterized by hyperaccumulation of fibrous tissue components and is commonly observed in latter or terminal states of chronic hepatic diseases. In this study, the antifibrotic effects of GLM001 on liver cirrhosis were examined in bile duct ligated rats and patients with hepatic diseases. GLM001 (250 mg/kg rat weight/ day) was administrated to cirrhotic rats for 4 weeks and to humans for 14 weeks. Bile duct ligated rats significantly increased liver collagen content and biochemical markers of hepatic injury. Liver histology showed collagen fiber deposition was increased and the normal architecture was lost with large zones of necrosis being observed frequently. GLM001 administrated rats showed significantly decreased liver collagen content, and accumulation of collagen fiber in histological analysis. Patients, who were treated with GLM001, showed decreases in biochemical markers of hepatic diseases. These results demonstrate the usefulness of GLM001 as an antifibrotic agent for liver cirrhosis.

This study was carried out to investigate the liver protective effects of extracts from Persicae Semen (WT-003, WT-005, WT-006). The acute hepatic injury was induced by intraperitoneal injection of alpha-naphtylisothiocyanate (75 mg/kg, p.o.) and treated with WT-006 (100 mg/kg/day, 200 mg/kg/day, 400 mg/kg/day). The experimental hepatic fibrosis was induced by bile duct ligation／scission(BDL/S), duration of 4 weeks and treated with WT-003, WT-005 or WT-006 (200 mg/kg/days for 4 week). In acute liver injury, WT-006 (200 or 400 mg/kg) lowered serum alanine transferase(ALT) and aspartate transferase(AST) significantly. In fibrotic rats, WT-006 treatment inhibited the hydroxyproline deposition in liver and lowered serum AST, ALT and ALP, significantly. These results suggest WT-006 extract, which does not contain amygdalin, from Persicae Semen have liver protective and antifibrotic effects in rats.

Pulmonary fibrosis is a serious lung disease that occurs predominantly in men. Genistein is an important natural soybean-derived phytoestrogen that affects various biological functions, such as cell migration and fibrosis. However, the antifibrotic effects of genistein on pulmonary fibrosis are largely unknown. The antifibrotic effects of genistein were evaluated using in vitro and in vivo models of lung fibrosis. Proteomic data were analyzed using nano-LC-ESI-MS/MS. Genistein significantly reduced transforming growth factor (TGF)-β1-induced expression of collagen type I and α-smooth muscle actin (SMA) in MRC-5 cells and primary fibroblasts from patients with idiopathic pulmonary fibrosis (IPF). Genistein also reduced TGF-β1-induced expression of p-Smad2/3 and p-p38 MAPK in fibroblast models. Comprehensive protein analysis confirmed that genistein exerted an anti-fibrotic effect by regulating various molecular mechanisms, such as unfolded protein response, epithelial mesenchymal transition (EMT), mammalian target of rapamycin complex 1 (mTORC1) signaling, cell death, and several metabolic pathways. Genistein was also found to decrease hydroxyproline levels in the lungs of BLM-treated mice. Genistein exerted an anti-fibrotic effect by preventing fibroblast activation, suggesting that genistein could be developed as a pharmacological agent for the prevention and treatment of pulmonary fibrosis.

The antifibrotic effects of hot water extract (WEC), intracellular biopolymer (IPC) and extracellular biopolymers (EPC) from mycelial liquid culture of Cordyceps militaris on liver fibrosis were studied. Liver fibrosis was induced by a bile duct ligation and scission (BDL/S) operation, duration of 4 weeks in rats. In BDL/S rats, the levels of aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), total bilirubin in serum and hydroxyproline content in liver were dramatically increased. The WEC or IPC treatment (30mg/kg/day for 4 weeks, p.o.) in BDL/S rats reduced the serum AST, ALT and ALP levels significantly (p<0.01). The EPC treatment (30 mg/kg /day for 4 weeks, p.o.) reduced the serum ALT, AST and ALP levels significantly (p<0.01). Malondialdehyde contents in liver treated with WEC, IPC or EPC were significantly reduced (p <0.05). But Liver hydroxyproline content was decreased only in EPC treated BDL/S rats to 55% that of BDL/S control rats (p < 0.01). The morphological characteristics and expression of alpha smooth muscle like actin in fibrotic liver, which appeared in BDL/S control group were improved in EPC treated fibrotic liver. These results indicate that IPC (30 mg/kg /day for 4 weeks, p.o.) has an antifibrotic effect on fibrotic rats induced by BDL/S.
