“…In the esophagus, the presence of mucous glands was reported in the early period of this century with considerable species variations [7], In man, the glands are detected early in the embryo [9]: their distribution in esophageal glands proper and in esophageal cardiac glands is well established [1,3,7,16], as well as the large individual variations of their number [1]. The study of mucosubstances in these cells was limited as for now to very short re ports: positivity of the mucicarmine reaction [1], and presence of sulfate esters [5], This work illustrates the presence of sialo-and sulfomucins in the esophageal glands proper and at the esophagogastric junction in the eso phageal cardiac glands.…”

The application of histochemical tests on the mucous glands in the soft palate, uvula and esophagus (esophageal glands proper and esophageal cardiac glands) disclosed the presence of sulfate esters and carboxylic groups in the mucosubstances. The basophilia decreased progressively in the oral-aboral direction, acidic mucosubstances (sialomucins and sulfomucins) being prevalent in the uvula, being still abundant in the esophageal glands, and totally lacking in the gastric cardia glands immediately below the transition of Malpighian to gastric epithelium.

“…1983: Clerc andMei, 1983] and pathology [Bishop el al.. 1979]. Bensley [1902] concluded that the width of the cardiac gland region depends upon the species of animal. He also staled that typical cardiac glands con tain only mucous cells.…”

“…In addition, the cardiac glands of the human stomach are branched tubular glands w'hich are organized into lobule like complexes by the connective tissue of the lamina pro pria [Miyagawa. 1920: Krause etal.. 1978, Since Bensley's [1902] description of the cardiac glands of mammals, no one has studied these glands in detail. This is especially true in the cat, even though it has been used recently as an experimental animal [Biancani et al.…”

The cardiac region (pars cardiaca) of the cat’s stomach was examined with light and scanning electron microscopy. The glands are simple, coiled tubular, and contain mucus-secreting cells. Their surfaces are covered with microvilli which are concentrated on the boundaries of the mucus-secreting cells. A few cells interposed between the glandular cells are probably G cells. They are identified by apical projections of long microvilli into the lumen of the gland. The surface epithelial cells lining the cardiac region are covered by minute microvilli. The muscularis mucosae is not distinctly divided into two layers. However, a group of smooth muscle cells which are directed in a circular manner around the gastroesophageal junction is considered to be the distal esophageal sphincter.

The human pyloric glands are simple or branched tubular glands which spiral through the connective tissue of the lamina propria. They are comprised of three cell types: the pyloric gland (mucous) cell, the parietal cell, and endocrine cells. The mucous cell is the most common cell type in the human pyloric glands and is characterized by an abundance of secretory granules. The secretory granules are usually round in shape and vary considerably in diameter. They are membrane-bound and comprise a heterogeneous population. The larger granules contain a light staining amorphous material and often possess an area of increased electron density near the limiting membrane of the granule giving them a mottled appearance. A smaller, more electron-dense secretory granule also is found both in relation to the Golgi complex and cell apex.The morphological observations indicate that the mechanism of mucin production by the mucous cells of the human pyloric glands may be similar to that reported in other mucin-secreting cells.
