Abstract
Summary
Methods for the fixation of the cell cytoplasm employing pyrogallol or resorcinol in neutralized formaldehyde solution are outlined. Tissue pieces fixed with these solutions have, in general, shown few signs of distortion, and the protein cytoplasmic elements of the cells have appeared well preserved, such structures as mitochondria, secretion granules, and some of the specific types of granulation being well maintained. The advantages of these methods lie in the simplicity and rapidity of the procedures, the ease with which the tissue can be sectioned at a thickness of 1 to 2 micra, and the generally satisfactory results obtained.
