Histochemical Studies on Hydrolytic Enzyme Activities
Histochemical observations were carried out on various hydrolytic enzymes in the spontaneous mammary carcinoma of C3H-strain mice. Alkaline phosphatase activity was observed in the luminal border of the tubular structure and in the periluminal surface, which showed a cystic dilatation in ducts and papillae. Capillaries in the stroma showed a high enzymatic activity. Acid phosphatase activity wa...
متن کاملStudies on the Isolation of Metaphase Chromosomes
A method for the isolation of metaphase chromosomes from mouse L1210 leukemia cells has been developed. Cells, arrested at metaphase with colchicine, were exposed to hypotonic solution and the pH was then adjusted to 5.6 to stabilize the chromosomes. The metaphase figures were subsequently disrupted and the chromosomes isolated by a series of differential centrifugations in sucrose. The isolate...
متن کاملHistochemical and ultrastructural studies on experimental gastritis in mice.
Experimental gastritis was produced in BALB/c (? / +) mice by the method of neonatal thymectomy. This atrophic gastritis was confined to the gastric fundobody mucosa and spared antrum. The morphological changes in the gastric mucosa of this type of gastritis have been described in detail during the growth process after thymectomy (1, 2, 3, 6, 10, and 15 months). The mucosa! changes developed fr...
متن کاملHistochemical studies on rat liver proteins during 4-dimethylaminoazobenzene carcinogenesis.
Areas of preneoplastic livers characterized by intense RNA staining apparently represent the sites of neoplastic transformation. These hyperbasophilic foci, as well as the hepatomas, showed a marked decrease in the stain ing intensity of the cytoplasmic proteins in sections stained by the mercury-bromophenol blue method or the MillÃ3nreaction. Following extraction of the RNA, how ever, protein ...
متن کاملHistological and histochemical studies on the rat pituitary pars intermedia.
Inspite of the recent progress in the endocrinology of the anterior pituitary, a specific part of the adenohypophysis which is in a close contact with the neurohypophysis, i.e., the pars intermedia, has been left in a state of incomplete understanding both in morphology and physiology. For example, early reports by ITANO (1936) and BAILLIF (1938) dealing with the rat pars intermedia, indicated ...
