Protective effect of fufanghuangqiduogan against acute liver injury in mice

AIM: To study the effects and possible mechanisms of fufanghuangqiduogan (FFHQ) in mice with acute liver injury (ALI). METHODS: ALI was successfully induced by injecting carbon tetrachloride (CCl4) intra peritoneally and by tail vein injection of Bacillus Calmette Guerin (BCG) and lipopolysaccharide (LPS) in mice, respectively. Each of the two model groups was divided into normal group, model group, FFHQ (60, 120 and 240 mg/kg) treatment groups, and bifendate treatment group. At the end of the experiment, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), content of malondialdehyde (MDA), activities of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px) in liver homogenate were measured by biochemical methods. The activities of tumor necrosis factor-α (TNF-α) and interleukin-1 (IL-1) were determined by radio-immunoassay. Hepatic tissue sections were stained with hematoxylin and eosin and examined under a light microscope. RESULTS: In the two models of ALI, FFHQ (60, 120, 240 mg/kg) was found to significantly decrease the serum transaminase (ALT, AST) activities. Meanwhile, FFHQ decreased MDA contents and upregulated the lower SOD and GSH-px levels in liver homogenate. Furthermore, in immunologic liver injury model, FFHQ decreased levels of TNF-α and IL-1 in serum. Histologic examination showed that FFHQ could attenuate the area and extent of necrosis, reduce the immigration of inflammatory cells. CONCLUSION: FFHQ had protective effect on liver injury induced by either CCl4 or BCG+LPS in mice, and its mechanisms were related to free radical scavenging, increasing SOD and GSH-px activities and inhibiting the production of proinflammatory mediators.

Protective effect of Weikang decoction and partial ingredients on model rat with gastric mucosa ulcer

AIM: To investigate the protective mechanisms of Weikang (WK) decoction on gastric mucosae. METHODS: Ninety rats were randomly divided into nine groups of 10 each, namely group, model group, group with large WK dosage, group with medium WK dosage, group with small WK dosage, group with herbs of jianpiyiqi (strengthening the spleen and replenishing qi), group with herbs of yangxuehuoxue (invigorating the circulation of and nourishing the blood), group with herbs of qingrejiedu (clearing away the heat-evils and toxic materials), group with colloidal bismuth pectin (CBP) capsules. According to the method adopted by Yang Xuesong, except normal control group, chronic gastric ulcer was induced with 100% acetic acid. On the sixth day after moldmaking, WK decoction was administered, respectively at doses of 20, 10 and 5 g/kg to rats of the WK groups, or the groups with herbs of jianpiyiqi, yangxuehuoxue and qingrejiedu, 10 ml/kg was separately administered to each group every day. For the group with CBP capsules, medicine was dissolved with water and doses 15 times of human therapeutic dose were administered (10 mL/kg solution containing 0.35% CBP). Rats of other groups were fed with physiological saline (10 ml/kg every day). Administration lasted for 16 d. Rats were killed on d 22 after mold making to observe changes of gastric mucosa. The mucus thickness of gastric mucosa surface was measured. Levels of epidermal growth factor (EGF) in gastric juice, nitric oxide (NO) in gastric tissue, endothelin (ET) in plasma, superoxide dismutase (SOD) in plasma, malondialdehyde (MDA) in plasma and prostaglandin I2 (PGI2) were examined. RESULTS: Compared with control group, ulceration was found in gastric mucosa of model group rats.

An herbal formula,CGX,exerts hepatotherapeutic effects on dimethylnitrosamine-induced chronic liver injury model in rats

AIM： To evaluate the therapeutic effect of Chunggan extract （CGX）, a modified traditional Chinese hepatotherapeutic herbal, on the dimethylnitrosamine （DMN）-induced chronic liver injury model in rats. METHODS： Liver injuries were induced in Wistar rats by injection of DMN （ip, 10 mg/mL per kg） for 3 consecutive days per week for 4 wk. The rats were administered with CGX Coo, 100 or 200 mg/kg per day） or distilled water as a control daily for 4 wk starting from the 15^th d of the DMN treatment. Biochemical parameters （serum albumin, bilirubin, ALP, AST and ALT）, lipid peroxides, hydroxyproline, as well as histological changes in liver tissues were analyzed. In addition, gene expression of TNF-α, TGF-β, TIMP-1, TIMP-2, PDGF-β, and MMP-2, all of which are known to be associated with liver fibrosis, were analyzed using real-time PCR. RESULTS： CGX administration restored the spleen weight to normal alter having been increased by DMN treatment. Biochemical analysis of the serum demonstrated that CGX significantly decreased the serum level of ALP （P 〈 0.05）, ALT （P 〈 0.02）, and AST （P 〈 0.02） that had been elevated by DMN treatment. CGX administration moderately lowered lipid peroxide production and markedly lowered hydroxyproline generation caused by DMN treatment in accordance with histopathological examination. DMN treatment induced a highly upregulated expression of TNF-α, TGF-β,TIMP-1, TIMP-2, PDGF-β, and MMP-2. Of these, the gene expression encoding PDGF-β and MMP-2 was still further enhanced 2 wk after secession of the 4-wk DMN treatment, and was remarkably ameliorated by CGX administration. CONCLUSION： CGX exhibits hepatotherapeutic properties against chronic hepatocellular destruction and consequential liver fibrosis.

Effects of total glucosides of peony on immunological hepatic fibrosis in rats

AIM: To study the effects of total glucosides of peony (TGP) on immunological hepatic fibrosis induced by human albumin in rats.METHODS: Sixty adult male Sprague-Dawley rats were randomly divided into: Normal group, model group, TGP (60 and 120 mg/kg) treatment groups and colchicines (0.1 mg/kg) treatment group. On the day before the rats were killed, those in TGP or colchicine groups received TGP or colchicine as above from the first day of tail vein injection of human albumin. The rats in normal and model groups were only administered with the same volume of vehicle. At the end of the 16th wk, rats in each group were killed. Blood and tissue specimens were taken. Levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), nitric oxide (NO), content of malondialdehyde (MDA), activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-px), were measured by biochemical methods. Serum procollagen type Ⅲ (PC Ⅲ) and laminin (LN) were determined by radioimmunoassay. Liver collagen level was determined by measuring hydroxyproline content in fresh liver samples. Hepatic tissue sections were stained with hematoxylin-eosin and examined under a light microscope.RESULTS: Histological results showed that TGP improved the human albumin-induced alterations in the liver structure, alleviated lobular necrosis and significantly lowered collagen content. The antifibrotic effect of TGP was also confirmed by decreased serum content of LN and PCⅢ in TGP-treated group. Moreover, the treatment with TGP effectively reduced the hydroxyproline contentin liver homogenates. However, the level of ALT and AST increased in fibrotic rat but had no significance compared with normal control, whereas the ratio of A/G decreased without significance. TGP had no effect on level of ALT, AST and the ratio of A/G. Furthermore, TGP treatment significantly blocked the increase in MDA and NO, associated with a partial elevation in liver total antioxidant capacity including SOD and GSH-px.CONCLUSION: TGP has beneficial effects on hepaticfibrosis in rats by inhibition of collagen synthesis and decreasing oxidative stress.

Colchicine （0.0025 mmol/L, 0.0050 mmol/L, 0.0075 mmol/L） was used as a positive control.RESULTS： THH could significantly inhibit the assembly of isolated porcine brain tubulin at all tested concentrations.CONCLUSION： THH is capable of inducing aneuploidy in mammals via tubulin polymerization inhibition pathway and may pose a genetic risk to human beings.

Comparison of integrated Chinese and Western medicine with and without somatostatin supplement in the treatment of severe acute pancreatitis

AIM: To evaluate the therapeutic effect of the combined use of early short-term somatostatin and conventional integrated Chinese and Western medicine in treating severe acute pancreatitis. METHODS: Sixty patients with severe acute pancreatitis were divided at random into a somatostatin group and a basic treatment group. Both groups received integrated traditional Chinese and Western medicine without surgery. For patients in the somatostatin group, somatostatin was infused intravenously 250 μg/h for 72 h; other medications were the same as in the basic treatment group. In both groups, comparisons of therapeutic effectiveness were made in terms of morbidity of organic dysfunction and mortality rate, and severity of the disease according to serum levels of C-reaction protein, scores of acute physiology and chronic health evaluation (APACHE Ⅱ), and scores of Balthazar-CT. RESULTS: The indexes for C-reaction protein levels on the fourth and seventh clays, and APACHE II scores on the seventh day after treatment, were significantly improved in the somatostatin group than in the basic treatment group. The morbidity of organic dysfunction was lower in the somatostatin group than in the basic treatment group, although the difference was not statistically significant. There was no significant difference in mortality between the two groups. CONCLUSION: We conclude that combined traditional Chinese and Western medicines with an early short-term use of somatostatin can improve the condition of patients with severe acute pancreatitis.
