A histoenzymological study was carried out on 40 tissues specimens removed at biopsy and for surgical operations of the following lesions: 5 normal oral mucosa, 5 periapical granulomas, and 30 periapical inflammatory cysts. The purpose of this study was to study some possibly significant variations in levels o activities of oxidative enzymes, and hydrolaxes enzymes. In inflammatory cysts, enzymatic activities were similar to normal epithelium. There was high levels of acid phosphatase LDH and G6PDH activity in the central cells of apical granulomas and in the exfoliating epithelial cells of periapical inflammatory cysts. There were differency in the glycosaminoglicans activity on the different epitelial pattern.

UI MeSH Term Description Entries
D007770 L-Lactate Dehydrogenase A tetrameric enzyme that, along with the coenzyme NAD+, catalyzes the interconversion of LACTATE and PYRUVATE. In vertebrates, genes for three different subunits (LDH-A, LDH-B and LDH-C) exist. Lactate Dehydrogenase,Dehydrogenase, L-Lactate,Dehydrogenase, Lactate,L Lactate Dehydrogenase
D007931 Leucyl Aminopeptidase A zinc containing enzyme of the hydrolase class that catalyzes the removal of the N-terminal amino acid from most L-peptides, particularly those with N-terminal leucine residues but not those with N-terminal lysine or arginine residues. This occurs in tissue cell cytosol, with high activity in the duodenum, liver, and kidney. The activity of this enzyme is commonly assayed using a leucine arylamide chromogenic substrate such as leucyl beta-naphthylamide.

D009061 Mouth Mucosa Lining of the ORAL CAVITY, including mucosa on the GUMS; the PALATE; the LIP; the CHEEK; floor of the mouth; and other structures. The mucosa is generally a nonkeratinized stratified squamous EPITHELIUM covering muscle, bone, or glands but can show varying degree of keratinization at specific locations.

D006025 Glycosaminoglycans Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).
