Summary Ultra-thin sections of heterophil granulocytes of clinically healthy, laying hybrid-hens were examined by electron microscope. Within the cytoplasm of these cells, round, oval or fusiform granules (rods) of different electron density were found. Osmiophilic and electron light areas (cores) were seen, either together within the same granular body, or separately in different granules. 相似文献

Summary By plotting the tension developed during maximal summation of muscle twitches against the stimulus interval, a curve can be drawn which has the same time course of the falling phase of the active state as determined by the method of quick release. 相似文献

Summary Report on a method to produce, without refrigeration and solvents, a tobacco smoke condensate of the tobacco main-stream smoke of the particulate phase. Identification obtained by the electron fine beam diffraction of crystals in the sediment of the smoke condensate of cigarettes and cigars.

Summary It is demonstrated that the acetylation of sulfanilamide and of p-amino-azobenzene, in the presence of pigeon liver extract and coenzyme A, is not only inhibited by -phenyl fatty acids but also by a considerable number of other substances. The most effective inhibitors contain at least two benzene nuclei and one acidic group (phenolic hydroxyl or a carboxyl group). 相似文献

Summary When fluoride-ions or monoiodoacetate is added to the ambient medium, there occur in fish larvae after 12 h, and in eels after 24 h, in some places, solid epidermal proliferations. The effect of glycolysis inhibitors on epidermal mitotic activity might be due to an impairment of energy metabolism as it is nullified by a simultaneous application of inorganic diphosphate or by doubled O2 partial pressure of 320 mm Hg. 相似文献

Summary The thermo-elastic properties of nerve have been studied by measurements of the change in length caused by changes in temperature. The thermal coefficient (per °C) of linear expansion, always positive in sign, is of the order of 10–4 for intact nerve and 10–5 for dissected nerve. 相似文献

Summary In order to measure the clotting time of blood plasma the sol-gel transformation is observed. The process is retarded with mol/18 of 1,4-oxyphenyl-sulfonate. A lowering of the prothrombin content of 50% results in a difference of time against normal values of 45–55 sec., compared with 3–4 sec. with the method ofQuick. 相似文献

Summary After perfusion of the rat portal vein with the plasmaexpander Haemaccel, the morphological findings suggest an active transport of this material by means of cytopempsis. Moreover, the until now rarely described existence of microtubules in vascular endothelia could be confirmed. Their function might be that of a cytoskeleton. 相似文献

Summary The lamellar system of chloroplasts consists of close double lamellae. In electronphotomicrographs, the walls of two adjacent double lamellae can be seen as one thick lamella. Because of this, the lamellae in the inner portion of a lamellar packet appear about twice as thick as those at the boundary of the packet and, in chloroplasts that contain grana, the granalamellae appear twice as thick as the stromalamellae.

Summary Three groups of fibres with different EPSP were differentiated in the claw-opening muscle of crayfish. Small and late depolarization of the deep fibres was observed on application of 3–4 times the normal concentration of KCl.

Summary The disappearance of thrombin—formed in the blood, or added to serum-follows a manomolecular reaction-type. Heparin increases the reaction-velocity of this thrombin-inactivating process.Our investigation established that toluidine blue or kinase, which, according to the literature, bind heparin, strongly reduce the speed of thrombin-inactivation too. Therefore the heparin-binding capacity of these substances is also manifested in the decrease of thrombin-inactivation. 相似文献

Résumé Dans une étude histochimique on a montré que les inclusions cytoplasmiques des tumeurs pulmonaires de la souris (Klärner etGieseking) contenaient une polysaccharide neutre jointe à l'acide ribonucléique. Les résultats ont été discutés au sens d'une hypothèse virale. 相似文献
