Histochemical Demonstration of Oxidative Enzymes in Human Salivary Glands

Histochemical Demonstration of Oxidative Enzymes in Human Salivary Glands.

Recently, the salivary glands function from biochemical, physiological and histochemical standpoints have been rather highlighted. Many investigators have come to try a histochemical detection of enzymes participating in various metabolic pathway in the salivary glands of experimental animals and humans. The previous study of this series dealt with the histochemical demonstration of various hyd...

Phosphatidylinositol-hydrolysing enzymes in blowfly salivary glands.

The salivary glands of adult blowflies (Calliphora erythrocephala) contain enzymes that hydrolyse phosphatidylinositol, predominantly by a Ca2+-independent deacylation, though a Ca2+-dependent phosphodiesterase (phospholipase C) activity could be detected. The deacylating enzymes could also hydrolyse phosphatidylcholine and phosphatidylethanolamine, and were secreted in the saliva. Homogenizati...

Histochemical Demonstration of Transglycosylases and Oxidative Enzymes in the Paget Cells of Extramammary Paget's Disease.

Although many histochemical investigations have been reported on the mucin in the cytoplasm of PAGET cells (LENNOX and PEARSE 1954, STRAUSS 1957, JOHNSON and HELWIG 1963, SASAI, AKIBA and TANAHASHI 1964), there are but few reports concerning an enzymohistochemistry in those cells (BRAUNFALCO and RATHJENS 1955, FANGER and BARKER 1959, STEIGLEDER and KAMEI 1963). In general, it is accepted that t...

Oxidative Damage to the Salivary Glands of Rats with Streptozotocin-Induced Diabetes-Temporal Study: Oxidative Stress and Diabetic Salivary Glands

Objective. This study evaluated oxidative damage caused to the salivary glands in streptozotocin-induced diabetes (DM). Materials and Methods. Rats were divided into 4 groups: groups 1 and 2, control rats, and groups 3 and 4, DM rats. 8-Hydroxy-2'-deoxyguanosine (8-OHdG), protein carbonyl (PC), 4-hydroxynonenal protein adduct (4-HNE), oxidized and/or MDA-modified LDL-cholesterol (oxy-LDL/MDA), ...
