Gastrin- and somatostatin-immunoreactive cells of the antral mucosa in patients with duodenal or gastric ulcers. An immunocytochemical study.

Gastrin- and somatostatin-immunoreactive cells in biopsies taken from the prepyloric portion of the antrum from 15 patients with duodenal ulcer, 16 patients with gastric ulcer, and a control group of 19 patients without histopathological alterations of the antral mucosa were studied using peroxidase anti-peroxidase and immunogold-silver staining methods in combination with morphometry. Numerical densities and sizes (immunoreactive areas) of the cells demonstrated were measured and compared between all three groups. Gastrin- and somatostatin-immunoreactive cells were located most frequently in the lower midzone of the gastric crypts.

[Value of the Miller-Abbott tube in the treatment of postoperative ileus].

This comparative study reports about therapeutic procedures in postoperative ileus. A group of 51 patients was treated with the Miller-Abbott-tube, placed by endoscopy, another comparable group, covering 41 patients, was attended by primary relaparotomy. The present study describes indications, technique, and problems of the Miller-Abbott procedure; success and failure in both groups are compared and discussed.

Phospholipase-A1 and -A2 in experimental acute pancreatitis in rats.

Using a standardized model of bile-induced acute pancreatitis, the reaction of phospholipase-A1 activity was investigated in parallel to that of phospholipase-A2, as well as their relationship to the pathomorphological spread of pancreatitis. While the measurement of the total free fatty acids (FFA) in serum as metabolites of phospholipase-A activity indicated variable reactions with the average remaining the same (0.186 +/- 0.

[Treatment of impalement with rectal lesion--"distal wash-out" (author's transl)].

A case of impalement with extensive rectal lesion is reported. The "distal wash-out" method using the antiseptic PVP-Iodine was used. The treatment is described.
