Cytological Studies on Two Functional Hepatomas

The Reuber hepatoma H-35 and Morris hepatoma 5123 have been studied by electron microscopy and by cytochemical staining methods for a number of phosphatases. These studies emphasize the resemblances of the two tumors to rat liver, but they also indicate distinctive features in each of the three tissues. Secretory product accumulates within the cisternae of the Golgi apparatus that dilate to for...

The effect of thioacetamide on rat liver regeneration. I. Cytological studies.

Partial hepatectomy initiates a complex pattern of cellular changes in the parenchymal cells of the residual liver. The sudden shift of the cell population from normal functional biosyntheses toward syntheses in preparation for cell division provides an ideal system for the study of various aspects of cell metabolism. The morphological and biochemical changes associated with liver restoration h...

Cytological Studies on Virus Diseases Op Solanaceous Plants '

Microscopical examinations of the tissues of mosaic-diseased plants have been made by numerous investigators since the earliest recognition of diseases of the plant virus group. With a few exceptions, these investigations have been confined to the study of a single virus disease upon a single species of host. It has now, however, come to be recognized that there are a number of different virus ...
