The occurrence of alpha1-fetoprotein in nonmalignant changes of the gastric mucosa was investigated by means of immunohistochemistry and radioimmunoassay. The investigations were performed in tissue sections, cytological imprint preparations as well as in homogenized tissue samples (obtained by gastroscopy). alpha1-fetoprotein could be demonstrated by immunohistochemistry in about 90% of the samples originating from the surroundings of gastric ulcer and the region of gastrojejunostomy after B II-resection. The RIA was positive in about 75% of the tissue samples, whereas from gastric juice only 40% of positive results could be obtained. No alpha1-fetoprotein-activity could be demonstrated in serum samples. These investigations indicate that alpha1-fetoprotein is not exclusively synthesized by embryonic or neoplastic tissues and also can be synthesized also by regenerating cell-systems. It may be supposed that this synthesis represents an unspecific answer to growth-stimulation.

Peroral staining with tolonium chloride (toluidine blue) was performed in 45 patients with suspected gastric ulcer disease. During endoscopy, 19 of 21 malignant ulcers and one of 15 benign ulcers were stained. Following surgery, 18 of 21 malignant ulcers found in the surgical specimens were stained. Eleven patients with benign ulcers underwent surgery and none of these ulcers were found to be stained in the surgical specimens. Normal gastric mucosa and areas of gastritis appeared unchanged. The data suggest that tolonium chloride staining prior to endoscopy or surgery seems to be helful in differentiating between minute benign and malignant gastric ulcers.

Four patients who apparently had benign gastric ulcer (G.U.) were treated with cimetidine. The ulcers healed and their symptoms disappeared. However, when cimetidine was stopped the symptoms recurred. Intramucosal cancer was found only at histopathological examination of the resected stomachs in two of the four patients, and in all the cases malignancy had not been detected by the initial serial biopsies and brush cytology. Relief of symptoms of malignant gastric ulcers by cimetidine may delay diagnosis and appropriae treatment.

The distribution and numbers of G cells and of parietal cells were related to the distribution and severity of histopathological alterations (inflammatory cell infiltration, atrophy and intestinal metaplasia) in corresponding mucosal tissue blocks from resected stomachs (12 patients with gastric ulcer, 11 with duodenal ulcer, and 14 with duodenal ulcer and uremia). In all patients the histopathological features were more severe in the pyloric antrum than in the body, and the change in severity corresponded well with the disapperance of G cells at the body-antrum border. The transitional body-antrum zone was histopathologically similar to the remaining antrum. A marked individual heterogeneity of the histopathological alterations was observed. An increasing grade of atrophy was associated with increased severity of inflammation, and the presence of intestinal metaplasia was especially associated with atrophy. No significant correlation was found between the antral G-cell number and the grade of antral inflammatory cell infiltration, whereas there was a reduction in cell number with increasing grade of atrophy in all patient categories. The parietal-cell density in the body mucosa was decreased with increasing grade of inflammation as well as with increasing grade of atrophy. The presence of patchy intestinal metaplasia resulted in a complete absence of G cells and of parietal cells from the corresponding part of the mucosa in the antrum and body respectively.

The effect of cimetidine on the risk of further bleeding shortly after acute gastrointestinal haemorrhage from peptic ulcer was investigated in a double-blind randomised trial. 34 patients were given cimetidine and 32 placebo, the two groups being matched for age, sex, and severity of haemorrhage. Further bleeding within a week of admission was detected clinically in 8 patients on cimetidine and 15 on placebo. Cimetidine had no effect on bleeding from duodenal ulcer, but only 2 of 14 patients with gastric ulcer treated with cimetidine bled again, compared with 10 of 19 patients on placebo. Cimetidine, therefore, may help to prevent haemorrhage from gastric ulcer but not duodenal ulcer.

One patient was seen with Candida albicans infection in a gastric ulcer. Gastric biopsy was of value in the diagnosis. The patient responded well to Nistatin therapy.

A histalog gastric analysis was done in 20 patients with gastroduodenal disorders and 12 subjects with non-ulcer dyspepsia who were used as controls. Due to overlap of secretory responses its use as a diagnostic tool is limited. About 46% patients with duodenal ulcer exceeded the upper limit of acid secretion of control subjects. Values for stimulated secretion in controls and the patients with gastric ulcer were the same. Endoscopy if possible is the investigation of choice for the diagnosis of gastroduodenal disorders and the secretory studies should be limited to patients under-going surgery for peptic ulceration.

In this report of 264 operatively treated gastroduodenal perforations, differentiated, and where possible definitive, therapy is attempted. By omitting simple oversewing in favor of primary resection, bionomic operation or the combined procedure, primary lethality is reduced to one third and the late results of the survivors significantly improved. Resections are indicated in benign pyloric stenosis and gastric ulcer. The bionomic operation is particularly to be preferred in young patients.

The antigen common for continuous epithelial cell lines and gastric mucosa of humans described earlier was studied. This antigen was revealed in one more cell line, namely in that prepared from human mammary carcinoma MDA-MB-231, noncontaminated with HeLa cells. The antigen described can be detected in the exophytely growing adenocarcinomas of the stomach and in the mucosa of the carcinoma affected stomach at a distance of 10--12 cm from the site of affection; no such antigen was revealed in the endophytely growing carcinoma of the stomach and in mucosa areas surrounding gastric ulcer. The antigen is not a glycoprotein since glycoprotein fractions obtained by means of 1.2 M perchloric acid from the normal stomach mucosa homogenate and the E 16b extract were inactive in immunodiffusion with a sensitive serum. The electrophoretic mobility of the antigen was similar to that of globulin alpha1-beta2. This antigen is of interest since its detection or absence would possibly aid in determination of the initial type of cells from which development of carcinoma occurred, and in more precise recognition of the histological form of carcinoma of the stomach.

A systematic prospective endoscopic study of the incidence of juxtapapillary diverticula in a variety of digestive disorders was undertaken in the Surgical Clinic at the Provincial Hospital, Port Elizabeth. The findings were related to conditions commonly encountered. The following frequency distribution was found: 33 diverticula out of 164 patients associated with gallstones (20.1%); 15 out of 668 patients not associated with gallstones (2.2%); 1 out of 39 patients with pancreatitis (2.6%); and 3 out of 146 patients with gastric ulcer (2.1%). No diverticulum was noted in 111 patients with duodenal ulcer. These findings suggest that juxtapapillary diverticula are nearly 10 times more common in patients with gallstones than in patients without. There is evidence to suggest that these diverticula tend to precede the gallstones. It is conceivable that juxtapapillary diverticula may predispose to gallstones. Alternatively, both conditions may be manifestations of another underlying disorder as yet to be defined.
