Electron microscopical findings in hypertrophied human ventricle.
The, normal ultrastructure of the human myocardium is fairly well documented (Porter and Bonneville, 1963; Stenger and Spiro, 1961; Burdette and Ashford, 1963; Lannigan and Zaki, 1966) and some of the prominent subcellular changes have also been described (Burgos and Rodriguez-Echandta, 1966; Alexander, 1967). We should like here to present the ultrastructural features observed in hypertrophied...
متن کاملElectron microscopical investigation of asbestos fibers
Examination of asbestos fibers by electron microscopical techniques enables the observer to distinguish among the fiber types by morphological and structural characteristics. Chrysotile asbestos fibers are composed of bundles of fibrils. Fibers are often curvilinear with splayed ends. Individual fibrils consist of a central capillary defined by an electron dense crystalline wall. With increasin...
متن کاملElectron Microscopical Studies of Prozen-dried Yeast
The periodate S c h i f f reaction has been used to localize polysaccharides in frozen-dried speci mens of several genera of the Endomycetales, of which three representatives are here described. No PAS reactive cell wall component was detectable in Schizosaccharomyces, in contrast to the distinctly reactive cell wall layer in N adsonia, Saccharom ycodes and Saccharomyces. These findings are in...
متن کاملScanning electron microscopical examination of gonococcal urethral exudate.
The relationship of gonococci and phagocytes in gonococcal urethral exudate was examined using a scanning electron microscope. Several stages in the phagocytic process were evident. These included pseudopodias, microvilli, and simple attachment of gonococci to phagocytic surfaces. Epithelial cells, also a part of the exudate, were examined in this study. Parallels are drawn between this and oth...
متن کاملA Comparative Electron Microscopical Study of Rna from Different Sources
Electron micrographs of ribosomal RNA from Escherichia coli, microsomal RNA from calf, rat, and chick liver, Bacillus cereus RNA and E. coli soluble RNA are presented. Filaments of about 10 A in diameter could be observed in preparations obtained from aqueous solutions of high molecular weight RNA. When ammonium acetate solutions were used a tendency for coiling and aggregation was observed. E....
