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 esterases in the chicken central nervous system.
Tritolyl phosphates have caused many cases of poisoning in humans involving damage to. the nervous system which is characterized clinically by ataxia and paralysis of the limbs (Smith, Elvove, Valaer, Frazier & Malleroy, 1930; Henschler, 1958); also, in the hen a similar type of poisoning is produced and this species is therefore accepted as a suitable experimental animal for studying this type...
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 کاملHistochemical demonstration of chymotrypsin like serine esterases in mucosal mast cells in four species including man.
Serine esterases were detected in the granules of mucosal mast cells from rat, mouse, sheep, and man. Successful demonstration of enzyme activity required brief fixation (6 h) of tissues in 4% paraformaldehyde. Staining with naphthol AS-D chloroacetate produced an intense red reaction product in intraepithelial mucosal mast cells (globule leucocytes) and mucosal mast cells within the lamina pro...
