[Stereologic analysis of myocardial ultrastructure during the postresuscitation period]. 1981

P N Eskunov, and V V Semchenko, and L V Poluéktov

The myocardium of dogs which suffered the 5-minute clinical death was subjected to ultrastructural stereologic examination. It was found that the T system density volume in cardiac myocytes was drastically reduced because of the massive destruction of its tubules. The regeneration of the T system was slow in progress. The mitochondrial density volume was discovered to be reduced 6 hours after the resuscitation. The myocardial ultrastructure virtually returned to normal by the end of the second week of the postresuscitation period.

UI MeSH Term Description Entries
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
