Histochemical 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 Studies of the Effects of Monosodium Glutamate on the Liver of Adult Wistar Rats
BACKGROUND Monosodium glutamate (MSG) is a commonly used food additive and there is growing concern that excitotoxins such as MSG play a critical role in the development of several hepatic disorders. OBJECTIVES The histochemical effect of monosodium glutamate was investigated on the liver of adult Wistar rats. METHODS Adult male Wistar rats (n = 24), with an average weight of 230 g were ran...
متن کاملHistochemical 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 کاملHistochemical studies on nuclease activity and neoplastic transformation in rat liver during diethylnitrosamine carcinogenesis.
The distribution of RNase activity and the occurrence of hyperbasophilic foci and tumors have been examined in rat liver during diethylnitrosamine carcinogenesis. A focal loss of RNase activity was found to occur in the hyperplastic liver nodules prior to the development of hy perbasophilic foci and hepatomas. The RNase-negative areas were widely distributed in livers of rats treated with dieth...
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 ...
