2Nitric oxide synthase distribution in esophageal mucosa and hemodynamic changes in rats with cirrhosis显示文摘AIM To observe the nitric oxide synthase (NOS) distribution in the esophageal mucosa andhemodynamic changes in cirrhotic rats.METHODS NOS distribution in the loweresophagus of rats with carbon tetrachlorideinduced cirrhosis was assessed by using NADPHdiaphorase (NADPH-d ) histochemical method.Concentration of NO in serum were measured byfluorometric assay. Mean arterial pressure(MAP), cardiac output (CO), cardiac index (CI),splanchnic vascular resistance (SVR ), andsplanchnic blood flow (SBF ) were alsodetermined using 5’CO-labeled microspheretechnique.RESULTS Intensity of NOS staining in theesophageal epithelium of cirrhotic rats wassignificantly stronger than that in controls.There was a NOS--positive staining area in theendothelia of esophageal submucosal vessels ofcirrhotic rats, but the NOS staining was negativein normal rats. NO concentration of serum incirrhotic rats were significantly higher incomparison with that of controls. Cirrhotic ratshad significantly lower MAP, SVR and higherSBF than those of the controls.CONCLUSION SPlanchnic hyperdynamiccirculatory state was observed in rats withcirrhosis. The endogenous NO may play animportant role in development of esophagealvarices and in changes of hemodynamics incirrhosis.Huang YQ Xiao SD Zhang DZ Mo JZ 1999World Journal of Gastroenterology1999,5,3:22

13Preliminary study on light hydrocarbons in ore-forming fluids of gold and antimony deposits in southwestern Guizhou, China显示文摘METAL minerals precipitate generally from ore-forming fluid. It is suggested that organic mat-ter in ore-forming fluid is one of the best media which show the role of organic matter in oregenesis. Because mineralizing temperatures of many ore deposits exceeded the stable rangesof liquid hydrocarbons, only light hydrocarbons were preserved well in inclusions.

14Primary porcine hepatocytes with portal vein serum cultured on microcarriers or in spheroidal aggregates显示文摘AIM To develop a culture mode providingdurable biomaterials with high yields andactivities used in bioartificial liver.METHODS Hepatocytes were isolated from awhole pig liver by Seglen’s method of orthotopicperfusion with collagenase.In culture onmicrocarriers,primary porcine hepatocyteswere inoculated at a concentration of 5×10~7/mLinto the static culture systems containing 2 g/LCytodex-3,then supplemented with 100 mL/Lfetal calf serum(FCS)or 100 mL/L porcineportal vein serum(PPVS)respectively.Inspheroidal aggregate culture hepatocytes wereinoculated into 100 mL siliconized flasks at aconcentration of 5.0×10~6/mL.RESULTS In culture on microcarriershepatocytes tended to aggregate on Cytodex-3obviously after being inoculated.Typical multi-cellular aggregated spheroids could be found inthe two systems 24 h-48 h after hepatocyteswere cultured.The morphological charact-eristics and synthetic functions were maintainedfor 5 wk in FCS culture system and 8 wk in PPVSculture system.In spheroidal aggregate cultureabout 80%-90% isolated hepatocytes becameaggregated spheroids 24h after cultured insuspension and mean diameter of the spheroidswas 100μm.The relationship among thehepatocytes resembled that in the liver in vivo.Synthetic functions of albumin and urea of the spheroids were twice those of hepatocytescultured on monolayers.CONCLUSION As high-yields and high-activitymodes of culture on microcarriers or inspheroidal aggregate culture with portal veinserum are promising to provide biomaterials forbioartificial liver(BAL)efficiently.Gao Y Hu HZ Chen K Yang JZ 2000World Journal of Gastroenterology2000,6,3:6
15Mechanical Behaviour and Microstructure Evolution of Superplastic Mg-8.4 wt pct Li Alloy and Effect of Grain Size and Phase Ratio on Its Elongation显示文摘Mechanical properties and microstructure evolution of Mg-8.4 wt pct Li alloy have been investi- gated. The superplastic elongation-to-failure 920% at 573 K and initial strain rate of 5 × 10-4 s-1 at low nominal stress 2 MPa has been demonstrated. It was shown through optical microstructure that the average grain sizes at gauge length section before and after superplastic tension and at grip section were 7.5 μm, 31.7 μm and 20 μm respectively, indicating significant deformation induced grain growth and static grain growth. Comparison of experiment data with published data for superplastic Mg-Li alloys shows that fine grain size and about 50 to 50 phase ratio contribute to achieving the largest superplasticity. Some related research works in other alloys are compiled and further evidences to such theoretic argument are provided.Cao, FR Cui, JZ Wen, JL Lei, F 2000Journal of Materials Science & Technology2000,16,1:5

18Quantum chemical studies on antimalarial of artemisinin (qinghaosu) derivatives显示文摘In this paper theoretical studies were performed on artemisinin (qinghaosu) derivatives with semiempirical quantum chemical methods AMI and PM3. The antimalarial activity -logC has an obvious correlation with the net charge of C(16) and bond orders of bonds O(1)-C(10), O(2)-C(6), O(1)-O(2) and O(5)-C(16).
