| 1 | Oscillations during partial oxidation of methane to synthesis gas over Ru/Al_2O_3 catalyst显示文摘Oscillations in temperatures of catalyst bed as well as concentrations of gas phase species at the exit of reactor were observed during the partial oxidation of methane to synthesis gas over Ru/Al2O3 in the temperature range of 600 to 850 ℃.XRD,H2-TPR and in situ Raman techniques was used to characterize the catalyst.Two types of ruthenium species,i.e.the ruthenium species weakly interacted with Al2O3 and that strongly interacted with the support,were identified by H2-TPR experiment.These species are responsible for two types of oscillation profiles observed during the reaction.The oscillations were the result of these ruthenium species switching cyclically between the oxidized state and the reduced state under the reaction condition.These cyclic transformations,in turn,were the result of temperature variations caused by the varying levels of the strongly exothermic CH4 combustion and the highly endothermic CH4 reforming(with H2O and CO2) reactions(or the less exothermic direct partial oxidation of methane to CO and H2),which were favored by the oxidized and the metallic sites,respectively.The major pathway of synthesis gas formation over the catalyst was via the combustion-reforming mechanism. | Meiliu Wang Weizheng Weng Haozhuan Zheng Xiaodong Yi Chuanjing Huang Huilin Wan | 2009 | Journal of Natural Gas Chemistry2009，18，3： | 3 |

| 8 | Experimental study of effect of Ganyanping on fibrosis in rat livers显示文摘AIM: To observe the effects of Ganyanping on CCl4-induced hepatic fibrosis in rats.
METHODS: The rats were separated randomly into five groups. Groups A to group D, each consisting of 15 rats,were for different tests, while 8 rats were used as normal controls (N). For group D, CCl4 was injected subcutaneously,at a dosage of 3 mi/kg for 9 weeks. For group A,Ganyanping was administered via gastric tube at a dosage of L0 mi/kg. For group B, the treatment with Ganyanping was started 4 weeks after CCl4 administration. Tn group C, Ganyanping was administered 8 weeks after the intoxication, and treatment lasted for 4 weeks. Liver tissues were fixed in 10 % formalin and embedded in paraffin. Pathologic changes, particularly fibrosis, were evaluated on the HE and V-G-stained sections. Ten middlepower fields were randomly selected for assessment of collagen deposition.
RESULTS: Loss of normal hepatic architecture, some with pseudo-lobule formation, was observed in group D, while hepatocytes steatosis and fibrosis were less pronounced in the animals treated with Ganyanping. Pseudo-lobule formation was not evident in the latter groups. The total collagen area and ratio were 840.23±81.65 and 7.0+0.9,respectively in group D, the ratio being reduced greatly in the Ganyanping-treated groups (148.73+45.89 and 1.16+0.33, respectively). The activities of MAO and ACP were elevated and that of SDH in group D decreased in the hepatic tissue as compared to the control group. The treatment with Ganyanping abrogated these enzymatic changes.
CONCLUSION: Our data approved that Ganyanping could improve the microcirculation in the liver, reduce oxygenderived free radicals, and enhance the cellular metabolism and immune function, all resulting in an anti-fibrotic effect.Hence, Ganyanping can protect the liver from fibrosis. It may be a safe and effective preparation for patient with fibrosis. | GuoZhang MeiLiu QinLi Shao-BaiLi Wang-XianTang Zi-LiDan Hong-MeiYah Cui-HuanWu | 2003 | World Journal of Gastroenterology2003，9，6： | 1 |
