To the Ultrastructural Organization of Epitheliocytes of Exocrine Glands

Abstract

Pieces of the sublingual multi-duct salivary glands of a domestic sexually mature large white pig were fixed in a 4 % paraform solution in 0.1 M phosphate buffer (pH = 7.4) with addi-tional fixation in a 1 % OsO4 solution, dehydrated in alcohols of increasing concentration. Taking into account the recommendations of G. Gayer, pieces of organs were poured into araldite accord-ing to the standard technique. Contrasting was performed according to Reynolds. In the cytoplasm of the mucocytes of the sublingual multi-duct salivary gland, the agranu-lar endoplasmic reticulum predominates, which gives oxyphilic staining. According to electron microscopic studies of mucous glandulocytes in the acini of the sub-lingual salivary glands of domestic pigs, the secretory vacuoles of the cytoplasm are large, with pro-nounced electron-dense membranes. The content of vacuoles in mucocytes of one acinus is differ-ent.

“…Veterinary and sanitary expertise determines quality of the inspected product, certificate on using this product for a variety of ends is given on the base of it. The important part of veterinary and sanitary expertise of meat products is detection of possible adulteration, that is substitute of more expensive meat by less expensive one [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The attempts to pass wild animal meat as for livestock one can happen after illegal hunting, when wild animal meat was taken by illegal means.…”
