Résumé On a isolé du collagène naturel et polymère du tissu du manteau du calmarLoligo peallii par la méthode de Nishihara, les fibres présentant au microscope électronique une périodicité de 680 Å. Le collagène a une composition typique d'amino acides et contient l'hydrate de carbone dans une proportion restreinte; principalement sous forme de glucose et de galactose. 相似文献

Summary Following 1 h exposure, the level of phospholipase A2 penetration into the axoplasm of the squid giant axon was 107 to 350% of that in the external media; corresponding values for phospholipase C were 18 to 31%. Phospholipases can therefore be used to study phospholipid function in axons since they can penetrate through connective tissue and Schwann cell to reach the axolemma.I thank Dr.Toshio Narahashi for allowing me to use his laboratory facilities at the Marine Biological Laboratory, Woods Hole, Mass. for the dissection of squid axons. Expert technical assistance in these studies were provided by Mr.Steven Trudel and Mr.Stuart Owen Rosenberg. This work was supported in part by a grant from the University of Connecticut Research Foundation. 相似文献

Summary The cultivation of a rheumatogenic strain of group A streptococcus in presence of human heart valve connective tissues leads to the release of substance(s) reacting with antistreptococcal polysaccharide and antihuman glycoprotein antibodies. 相似文献

Summary Isolated cardiac cells from bullforg atrial tissue can be readily prepared by digestion of intact fragments of atrial tissue with trypsin and collagenase. These isolated cells have dimensions of about 5 m in width and range in length from 300 m to over 500 m. Such isolated cells may prove useful for the investigation of contractile activity of cardiac muscle at the single cell level and at the sarcomere level within the single cell.This investigation was supported by U.S. Public Health Service, National Institutes of Health Grant No. HL 12426 and a Kansas Heart Association Grant-in-Aid.We wish to thank Dr.J. Sommers of Duke University Medical Center for doing electron microscopy of the isolated cells to confirm the single cell nature of the preparations. 相似文献

Isolated cardiac cells from bullfrog atrial tissue can be readily prepared by digestion of intact fragments of atrial tissue with trypsin and collagenase. These isolated cells have dimensions of about 5 mum in width and range in length from 300 mum to over 500 mum. Such isolated cells may prove useful for the investigation of contractile activity of cardiac muscle at the single cell level and at the sarcomere level within the single cell. 相似文献

Zusammenfassung Ein neues Antibiotikum, U-20661, wurde aus der Kulturflüssigkeit eines Streptomycetenstammes isoliert, welches in vitro nur gegen grampositive Bakterien wirksam ist. Die Substanz ist extrem cytotoxisch in Gewebekulturen, aber ungiftig für Mäuse. 相似文献

When the guinea-pig isolated ileum is treated with the Toxin II from Anemonia sulcata, it releases not only acetylcholine but also serotonin. These transmitters are both involved in the spasmogenic action of the toxin. 相似文献

Summary Factor XIII induces a decrease and a modification in the collagen polymerization, probably due to the formation of transamidation bonds. This property has some importance in wound healing. 相似文献

Résumé Nous avons trouvé que le facteur Hageman (factor XII), contenu dans le plasma humain citraté, pauvre en plaquettes, est adsorbé presque sélectivement par le collagène. Il est également possible d'éluer ce facteur au pH alcalin. 相似文献
