Electron Microscopy

Fifth International Congress for Electron Microscopy, Volume 2: Biology focuses on the processes, methodologies, approaches, and principles involved in electron microscopy. The selection takes a look at some aspects of freeze-substitution in electron microscopy; fixatives for cytological and cytochemical studies; intramembranous localization of succinic dehydrogenase using tetranitro-blue tetrazolium; and evaluation of different methods of auto-radiography in electron microscopy. The book then examines the fixation of nuclear structures by unbuffered solutions of osmium tetroxide in slightly acid distilled water; some electron microscope observations on the contraction mechanism in vertebrate smooth muscle; arrangement of myofilaments in the oblique-striated muscles; and electron microscopic observations of cat splenic nerve fibers after fixation by freeze-drying. The text ponders on differentiation of oligodendroglia from migratory spongioblasts; morphological changes in the Purkinje-cells after orthostatic collapse; electron microscopic observations of the development of the neuroblast in the rabbit embryo; electron microscopic observations on the development of blood vessels in the nervous system of the rabbit embryo; and simple methods for nucleic acid and acid mucopolysaccharide localization in electron micrographs. The selection is a valuable source of data for researchers interested in electron microscopy.
