This paper describes the clinical presentation of 360 patients suffering from "dyspepsia" at the time of their initial visit to two hospitals in Yorkshire. Disease categories studied were cholecystitis, duodenal ulcer, gastric ulcer, gastric cancer, and "functional" dyspepsia, with at least 50 patients in each category. The findings of this series are contrasted with "textbook" descriptions of these conditions. Some contrasts are quite surprising-for example, most of the 360 patients claimed that their pain was not aggravated by food. It is suggested that one reason for diagnostic error in this area of medicine is that clinicians have a faulty mental "database" of information with regard to the presentation of the various diseases concerned.

The author examined the cytographs of gastritis, polyps and ulcers according to the materials of the prophylactic examination of a dispensary group, comprising 265 patients at high risk for gastric cancer. The differential features of the cytographs were examined in the cases in which the complex gastrogical investigation showed the concidence in the results of gastrofiberscopy, gastrobiopsy and cytological tests. The differential cytologic diagnosis of polyps and gastric ulcer is found to be possible in the presence of papillary structures in the first case, and in the second--a great variety of stromal infiltrate cell structure with the obligatory presence of lymphocytes, plasmatic cells, histiocytic elements, eosinophilous and neutrophilous leucoctyes. The differential cytological diagnosis between different histological forms of gastritis needs further studies.

Among 81 patients with malignancies of the stomach, the early (cancer of the gastric mucosa) was diagnosed in 10 (12.3%) patients. Timely diagnosis of the early gastric cancer requires multiple endoscopic examinations and aimed gastric biopsies of the edges and bottom of the ulcer. The analysis of the serial histological preparations permits to detect single or small aggregations of large mucous cells looking like cricoid cells (considered by the author as a sign of malignization) and less frequently like tumour tissue, in necrotic mass or in the proper layer of the mucous membrane. It is recommended that any gastric ulcer be considered as a possible ulcerative form of cancer and that the patients be mandatorily examined in specialized institutions where the differential diagnosis between peptic ulcer and ulcerative form of cancer may be performed by the method of gastroscopy with aimed biopsy.

Recent achievements of gastrointestinal endocrinology on the basis of new techniques enabled investigation of endocrine cells in pathological conditions. The present paper describes investigations of 56 surgical cases of the stomachs operated on for duodenal and gastric ulcer and gastric cancer. Argyrophilic cell hyperplasia was common in non-metaplastic antropyloric mucosa in duodenal ulcer cases, not so common, however, in gastric ulcer and gastric cancer. In metaplastic mucosa enterochromaffin (EC) cells predominated. Intestinal metaplasia appeared to be the most significant factor influencing endocrine cells spectrum within antropyloric mucosa. A new observation is described of argyrophilic cells seen in lamina propria apart from glandular epithelium. We consider a working hypothesis of neuroendocrine complex hyperplasia especially well marked in some cases of duodenal ulcer.

1. Electrophoretic separation of proteases from human gastric mucosal extracts of five patients with gastric ulcer, one with duodenal ulcer and three with gastric cancer were investigated by agar-gel electrophoresis at pH 8.3 and pH 5.0. 2. In the fundic mucosal study, there were seven faster moving proteases in all nine cases, but the slowest moving protease showed a slightly different picture in each case. In the antral mucosal study, two of eight cases showed mainly group II pepsinogens, seven of nine cases, however, showed the same results as in the fundic mucosal study. 3. In the cases of the nine mucosal extracts activated at pH 1.5 or pH 4.0, they all showed the same electrophoretic separation at each pH level. At these two pH levels, however, quite different electrophoretic patterns were observed. The presence of pepsin 3 appeared to diminish at the higher levels of pH, although that of pepsin 5 and pepsin 7 appeared to increase at pH 4.0 and above. Pepsin 6 appeared for the first time at pH 4.0 and existed at higher pH levels. 4. We thus conclude that electrophoretic patterns of pepsins in the gastric mucosal extracts are changeable depending on the pH level of the incubating medium, and further that diversity of pepsins in gastric juices may also depend on the pH level of gastric juices.

The distribution of parietal cells in the body mucosa, and of G cells in the antral mucosa, was quantitatively mapped in resected stomachs from 42 patients (12 with gastric ulcer, 11 with duodenal ucler, 14 with duodenal ulcer and uremia, and 5 with gastric cancer) who preoperatively had had their gastric acid secretion measured. In the material as a whole there was a significant positive correlation between the parietal-cell density and maximal acid output (MAO), and a significant negative correlation between the parietal-cell density and patient age. A significant positive correlation was found between the antral G-cell mass and basal acid output (BAO). When the individual patient categories were analyzed, the correlation between parietal-cell density and MAO were significant in the group with duodenal ulcer and uremia, and in the group with gastric cancer. Correlation between parietal-cell density and age was found only in the group with duodenal ulcer and uremia. There was no correlation between the parietal-cell density and various parameters of the antral G-cell population in the material as a whole or in any of the individual groups.

In 306 patients, fiberpanendoscopy and radiology were performed within a time interval of 7 days or less. In 196 cases, radiology was performed before endoscopy and in 110 cases after endoscopy. In cases with histologically unproven divergent findings, follow-up studies were performed. In the diagnosis of gastric ulcer and gastric cancer, endoscopy with biopsy was more accurate than radiology. In the diagnosis of hiatal hernia, radiology was more accurate. Important additional findings difficult or impossible to observe with endoscopy were present in 36% of the radiological examinations. Thus, the first examination should be endoscopy when ulcer or carcinoma is suspected. In patients with uncharacteristic epigastric symptoms, radiology should be performed first.

Gastric juice was neutralized (nGJ) in vivo by 80 ml of a phosphate buffer containing radiolabelled vitamin B12 as dilution indicator. Unprocessed nGJ was analyzed in the double gel diffusion technique for the presence of serum proteins using monospecific antisera. Alpha1-Acid glycoprotein (AGP) was found in a high incidence (36 out of 38 subjects) in nGJ of gastric cancer patients. AGP was also observed less frequently in nGJ of patients with Billroth II resections (6/15), metaplasia (11/52), gastric ulcer (3/24), chronic atrophic gastritis (2/26) and chronic gastritis (3/63). AGP was absent in the control group (0/21), in patients with surface gastritis (0/38) and in subjects with normal acid secretion (0/45). Immunochemical studies demonstrated no identity of AGP with human "gastrointestinal tumor associated antigens." In 7 out of 17 AGP positive samples immunochemical differences between gastric and serum AGP were observed.

The uninvolved gastric mucosa of gastric ulcer and gastric carcinoma patients has been compared in in vitro studies as regards their capacity to bind demethylchlortetracycline (DMCT). Dialysis experiments demonstrated excessive binding of DMCT in gastric cancer. Several electrophoretic fractions were observed that bound DMCT; it was demonstrated that these fractions differed in the uninvolved mucosa of gastric ulcer and gastric cancer patients.

This case-control study of Hawaiian Japanese indicated that gastric ulcer in the proximal portion of the pyloric antrum has features similar to those of gastric cancer. Such ulcers occurred at sites most frequently and most severely affected by intestinal metaplasia, although metaplasia tended to be more extensive with cancer than with ulcer. Metaplastic mucosa was more vulnerable to the action of pepsin and acid than was normal mucosa. The risk of ulceration would rise when a sufficiently lagrge area of the antrum was intestinalized and when the corpus continued to produce significant quantities of these substances. This study showed a strong association between salt intake, ulcer, and metaplasia. Significant but less dramatic associations were demonstrated between metaplasia and the use of traditional Japanese foods and smoking. The question was raised as to whether salt promotes ulceration or whether it potentiates the action of a mutagen that causes intestinal metaplasia.
