Submaxillary salivary glands

Paramyxoviruses Mumps virus Enveloped particles variable in size, 110-170nm in diameter, with helical capsids Infection in children produces characteristic swelling of parotid and submaxillary salivary glands. The disease can have neurological complications, e.g. meningitis, especially in adults... 

The boar sex pheromone, consisting of androstenol and androstenone, from the submaxillary salivary gland has been used commercially for artificial insemination of pigs. It was available as a spray under the trade name Suidor (formerly Jeyes Boar Mate) in Europe (Glei etal, 1989). Sows who did not assume the...

Label concentrations in the heart and submaxillary salivary glands were similar to those for l-[ N]glutamate (35). 

In Tn-syndrome the sialyl transfer must also be defective, but Dahr etaL could not measure it and have suggested that the enzyme in erythrocyte and leucocyte membranes differs from that in submaxillary salivary gland in requiring Gaipi,3GalNAxal-Ser as its substrate. Hence the structure produced by the sialyl transfer would be a trisaccharide, not a disaccharide, as in salivary mucins. In that case Tn-syndrome would require only one, and not two, enzyme defects. 

Amylase activity has been measured in rat submaxillary salivary gland during heat acclimation (34 °C). It was suggested that the observed decrease in enzyme activity is due to liver atrophy which occurs during prolonged exposure to heat. ...

Patterson136 also examined the odorous salivary glands of boars, a source of an unpleasant smell referred to as sex odor in reports from the 1930s.144-147 Soxhlet extraction of minced submaxillary glands with diethyl ether provided a solution that contained an unpleasant odor. The contents were tested for relative volatility by a simple experiment. 

The a-amylase activities of semm, liver, pancreas, submaxillary and parotid glands, saliva, duodenum, colon, lung, heart, spleen, kidney, and skeletal muscle of the domestic cat Felix catus) have been determined.As in most mammals, the highest a-amylase content was found in the pancreas. Levels in saliva and salivary glands were very low. a-Amylase activities of the serum, liver, and pancreas has a pH optimum of 7.0-7.5, and were reversibly inactivated by removal of chloride ion. 

Saliva is a hypotonic, slightly acid, watery excretion of the salivary gland. Man excretes 1 ml of saliva per minute, about 1,000-1,500 ml daily. The submaxillary gland is responsible for 10% of salivary secretion, the parotid only for 25%, and the sublingual for approximately 5%. Saliva secretion is blocked by metabolic inhibitors that interfere with the bioenergetic pathways, and is therefore believed to be an active process. 

The mucous membranes of the gastrointestinal, respiratory, and genitourinary tracts are lined with a variety of mucins, many of which are probably of the Ser-GalNAc and Thr-GalNAc types. These mucins are difficult to purify and detailed structural information has only been obtained for two salivary gland preparations, ovine submaxillary mucin (OSM) and porcine submaxillary mucin (PSM). 

PSM has been described in porcine submaxillary gland (McGuire, 1970 Section V,A,2) the HeLa cell enzyme appears to difiFer from this salivary gland enzyme in pH optimum, cation requirements, and Km for GDP-fu-cose. The fucosyltransferase which acts on protein-bound N-acetylglucos-aminyl termini may be related to one of the blood group fucosyltrans-ferases, discussed in Section V,B,2,c, which attach fucose into either (a, l->3) or (a, l->4) linkage with N-acetylglucosamine. 

Salivary glands— The salivary glands represent a network of accessory structures which are essential to digestion. Three pairs of salivary glands are of primary importance— parotid, submaxillary, and sublingual. Fig. D-18 illustrates the location of these glands. 

Saliva may also contain specific chemical information for individual recognition (Blass and Teicher, 1980) or kin recognition (Block etah, 1981 Smith and Block, 1990). The best-known example of a salivary pheromone is the mixture of androstenone and androstenol in the submaxillary glands of the boar.
