1Immunocytochemical identification and localization of APUD cells in the gut of seven stomachless teleost fishes显示文摘AIM To study the cell types,localization,distribution density and morphology of APUDcells in the intestinal mucosa of stomachlessteleost fishes.METHOD By using the peroxidase-antiperoxidase complex(PAP)immunocytochemical staining technique theidentification,localization and morphology ofimmunoreactive(IR)endocrine cells seattered inthe intestinal mucosa of grass carp(Cyenopharyngodon idellus),black carp(Mylopharyngodon piceus)and common carp(Cyprinus carpio)were investigated with 20kinds of antisera prepared against mammalianpeptide hormones of APUD cells,and likewise byusing avidin-biotin-peroxidase complex(ABC)method those of silver carp(Hypophthalmichthys molitrix),bighead(Aristichthys nobilis),silver crucian carp(Carassius gibelio)and bluntnose black bream(Megalobrama amblyocephala)were alsostudied with 5 different antisera.Thereplacement of the first antiserum by phosphatebuffered saline(PBS)was employed as a control.IR endocrine cells were counted with asquare-mesh ocular micrometer from 10 fieldsselected randomly in every section of each partof the intestine specimen.The average numberof IR endocrine cells per mm2 was counted toquantify their distribution density.RESULT Gastrin(GAS)-,Gastric inhibitorypeptide(GIP)-,glucagon(GLU)-,glucagon-likeimmunoreactants(GLI)-,bovine pancreaticpolypeptide(BPP)-,leucine-enkephalin(ENK)-and substance P(SP)-IR endocrine cells werefound in the gut of grass carp,black carp andcommon carp,and somatostatin(SOM)-IRendocrine cells were only seen in common carp.GAS-,GIP-and GLU-IR endocrine cells werefound in the intestinal mucosa of silver carp,bighead,silver crucian carp and bluntnose blackbream.Most of IR endocrine cells had the higherdistribution density in the foregut and midgut,and were longer in shape.They had a long apicalcytoplasmic process extended to the gut lumenand a basal process extended to adjacent cellsor basement membrane and touched with it.Sometimes,the basal cytoplasmic processformed an enlarged synapse-like structure in thecontiguous part with basement membrane.Thisphenomenon provided new morphologicalevidence for neuroendocrine and paracrinesecretory function of these enteroendocrinecells.CONCLUTION At least 8 kinds of IR endocrinecells were found in the gut of stomachlessteleost species for the first time in China.TheseIR endocrine cells scattering in the gut mucosabelong to the APUD system.Among them,thehormones secreted by SP-,ENK-,SOM-and GLU-IR endocrine cells belong to the peptides of dualdistribution in the brain and gut.This providednew evidence for the concept of brain-gutpeptide.According to the cell types,distribution density,morphologicalcharacteristics and variety in shape of APUDcells in the gut of stomachless teleost fishes,itis deemed that the digestive tract of fishes isalso an endocrine organ of great importance andcomplexity.Pan QS Fang ZP Zhao YX 2000World Journal of Gastroenterology2000,6,1:25

3Localization of HCV RNA and capsid protein in human hepatocellular carcinoma显示文摘INTRODUCTIONThe relation of HCV to hepatocytic carcinoma(HCC) has been emphasized recently in low HBVinfection countries and regions.The distributionpatterns of HCV in liver tissues are not wellunderstood although studies on HCV infection inblood and hepatocytes have been conducted byPCR.In this study,42 liver cancersDai YM Shou ZP Ni CR Wang NJ Zhang SP 2000World Journal of Gastroenterology2000,6,1:15

6Enthalpies of Formation of Binary Transition hcp Metal Based Alloys Calculated by Analytic Embedded Atom Method Model显示文摘A simple analytic modified embedded atom method (M EAM ) Inciuding a modified term for hcp metals has been developed from the MEAM applied to the fcc and bcc metals. The enthalpiesof formation of all binary alloy systems for eight transition hcp metals are calculated with theMEAM. The calculations are in agreement with the experimental data avallable and resultscalculated from the Miedema theory. One can conclude that our MEAM is also effective toapply to the hcp metals and their alloys.Zhang, BW Ouyang, YF Liao, SZ Jin, ZP 1999Journal of Materials Science & Technology1999,15,4:5
7Study of operator reliability in nuclear power plants显示文摘The study of the reliability of operator’s diagnosis and decision-making during abnormal events with HCR model has been introduced. A new approach has been proposed by the authors to deal with the classification of HIs. The modification of T0.5 by PSFs coefficients has been discussed. In addition, it is emphasized that T0. 5 and SD(σ) of response times can be used as a scale to predict and evaluate the reliability of crew/operator behavior. These processings provide improvement and refinement to HCR model and its practical application. The experiment for operator response time of Chinese NPP using a lull-scale simulator has proved the above-mentioned processings and presented the quantitative results of operator reliability in Chinese NPP.Yang, MZ Gao, J Zhao, BQ Huang, XR Shen, ZP 1997Chinese Science Bulletin1997,42,19:4
8DETERMINATION OF EFFECTIVE MODULI FOR FOAM PLASTICS BASED ON THREE PHASE SPHEROIDAL MODEL显示文摘The relations of bulk modulus,shear modulus,Young’s modulus and the Poisson’s ra-tio with porosity of foam plastics are determined by a three phase spheroidal model commonly used inComposite Mechanics.The results are compared with those using differential scheme.It is shownthat the material properties derived from the present model normally are larger than those obtained bydifferential scheme for foam plastics with identical porosity.The differences in shear moduli andYoung’s moduli obtained by the two methods are small,but they are larger for bulk moduli of incom-pressible matrix and Poisson’s ratios.The Young’s moduli of high density foam plastics derived by thepresent model agree better with experimental ones.Lu, ZX Huang, ZP Wang, R 1995Acta Mechanica Solida Sinica1995,8,4:3
