The anti-ulcer activity of three different doses (1/10, 1/30 and 1/90 of LD50) of imipramine, amitryptyline, chlorpromazine, amphetamine, ephedrine, chlordiazepoxide and meprobamate was studied in two types of stress-produced gastric ulcers in rats. It was found that these drugs given in doses of 1/10 or 1/30 LD50 inhibited in the same degree the development of gastric ulcer-produced by the method of Senay, in spite of differences in their psychotropic activity. On the other hand, when the method of Rossi was used for ulcer production the ulcer-preventing activity of these drugs has been varied. Thymoleptics were most effective and ataractics least effective against ulcers produced by the method of Rossi.

In the light of an analysis of late results of surgical treatment obtained in a group of 2450 patients with chronic gastric or duodenal ulcer subjected to various types of operations the author stresses the importance of choice of a proper surgical method. It is concluded that in treatment of chronic gastric ulcer the most appropriate method is partial gastrectomy including the whole pyloric part of the stomach. On the other hand, in chronic duodenal ulcer gastrectomy must be more extensive including over 70% of the gastric surface, it may be less extensive if associated with vagotomy. Truncal vagotomy with pyloroplasty should be applied only in high-risk patients in view of a high proportion of recurrences of peptic ulcer.

Gastric ulcer development and changes in the contents of glucose, free fatty acids (FFA), and K and Ca ions in the blood were studied in rats subjected to a graded stress of immobilisation and cold. During stress the volume of secretion and the output of HCl, decreased although the concentration rose slightly. Chlorpromazine (CPZ), thioridazine (TRZ), spiroperidol (SPI), and fluphenazine (FLU) inhibited to various degrees ulcer formation during stress. SPI reduced stress-induced mucosal damages in 94%, but FLU even in doses 100 times smaller than those of the other drugs counteracted ulcer formation. CPZ, TRZ and SPI in preventive doses increased proportionally the blood glucose level both in control rats and in those subject to stress. FLU in effective doses produced no hyperglycemia either in control rats or in those exposed to stress. We conclude that the prevention of gastric ulcer development by neuroleptics may be the result of their antisecretory action and counteracting of breakdown of sympathetic activity during severe stress.

Some subjective and objective symptoms, that are believed to be specific of peptic ulcer, were analyzed in 425 patients with endoscopically confirmed gastric ulcer. It was noted that the pain syndrome may have variants while pain after meals remains a typical sign of gastric ulcer. But asthenic habitus, tendency to sinus bradycardia and arterial hypotension, the absence of a coated tongue, and the tendency to erythrocytosis and decelerated ESR were not typical for the observed patients. The results suggest that some traditional concepts of typical clinical picture of peptic ulcer should be revised.

An attempt of the assessment of T-cells function in patients with gastric or duodenal ulcer has been undertaken. The studies involved 60 patients with gastric or duodenal ulcers and 47 individuals of the control group. Lymphocyte reactivity to different concentrations of concanavalin A and phytohemagglutinin has been assessed with leukocyte migration inhibition test. Lymphocyte T function has been examined also in patients with gastric or duodenal ulcers in reference to the theophylline-dependent and theophylline-sensitive subpopulation of T-cells. Leukocyte migration index values after phytohemagglutinin and concanavalin A did not differ significantly in patients with gastric or duodenal ulcers and theophylline-sensitive T-cells. Differences have been noted in the migration inhibition deficits. This phenomenon has been least frequent in case of phytohemagglutinin in the control group (5.8%) and most frequent in patients with gastric ulcer (62%). Percentage of patients responding to higher concanavalin A concentration (40 micrograms/ml) with leukocyte migration inhibition has been the highest in patients with duodenal ulcer. This index value has been significantly lower (p < 0.05) only in patients with duodenal ulcer and increased number of theophylline-dependent lymphocytes T. Increased reactivity of T-cells to higher concanavalin A concentration in patients with duodenal ulcer with theophylline-dependent T-cells in peripheral blood probably indicates increased the suppressor lymphocytes activity.

The effect of calcitonin on gastric emptying of a radiolabelled test meal was examined in 8 male patients with active gastric ulcer. The patients ate the test meal twice, whilst during one of the examinations they were given synthetic salmon calcitonin (415 pmol i.v. bolus + continuous infusion during 90 min to reach an overall dose of 62.25 pmol.kg-1 body mass) and during the other one they received placebo--in randomized order, according to a double-blind study protocol. In every patient a pronounced delay in gastric emptying after calcitonin was observed --the emptying index, Ix: 2.33 +/- 0.22 x 10(-2) min-1 (placebo) vs 0.81 +/- 0.18 x 10(-2) min-1 (calcitonin), p less than 0.001. Calcitonin delayed and significantly lowered the postprandial gastrin release, as well as suppressed the postprandial insulin release with a secondary change in the serum glucose concentration pattern, whereas the serum calcium and phosphorus remained unaffected. The authors conclude that salmon calcitonin in a pharmacological dose elicits a strong inhibitory effect on gastric emptying in gastric ulcer patients.

In the present report we have analyzed data reported in literature on the diagnostic accuracy of endoscopy and associated sampling techniques compared to standard and double contrast radiological examinations, as well as the rate of malignant transformation of benign gastric ulcer. Data on 117 patients with benign gastric ulcer examined in our Center between 1974 and 1984 are reported. From our experience, we may state that only one case underwent to malignant transformation, i.e. a rate of 1.2%, in agreement with recent literature. Three cases of malignant-ulcer had gone undiagnosed at first endoscopy, but were correctly diagnosed at a short-term re-examination. The present study, other than reconfirming the importance of the endoscopic examination with associated techniques, stresses the importance of aimed cytology and of short-term endoscopic re-examination as a mean for lowering the rate of false negative diagnoses.

Both misoprostol (synthetic PGE1 analog) and De-Nol (factor releasing endogenous prostaglandins in the gastric mucosa) can be useful in the treatment of patients with gastric ulcer resistant to cimetidine according to their gastroprotective properties. 64 patients whose gastric ulcer had not healed after 6 weeks of therapy with cimetidine in daily dose of 1000 mg were treated in a comparative short-term trial to assess the relative efficacy of misoprostol (Cytotec; Searle) in daily dose of 800 micrograms (I group; n = 32) and colloidal bismuth subcitrate (De-Nol; Gist-Brocades), four times a day in dose of 5 ml diluted with 15 ml of water (II group; n = 32). Both groups of patients were comparable according to age, sex, duration of ulcer disease, smoking habits, gastric acid secretion, ulcer size and localization in the stomach. The ulcer healing was controlled endoscopically after 2 and 4 weeks of the treatment. Healing rates after 2 weeks of therapy appeared to be 47% for misoprostol and 34% for De-Nol. After 4 weeks of therapy the healing rates were 72% with misoprostol and 63% with De-Nol. No statistically significant differences in the therapeutic efficacy were observed between two groups of the patients. No correlation was found between the ulcer healing rates and size of ulcer, its localization or smoking habits. The moderate side effects (transient diarrhea) were observed in 22% of patients treated with misoprostol. These findings suggest that misoprostol is as effective as De-Nol in the treatment of gastric ulcers resistant to cimetidine.

In the Institute of Maritime Medicine EEG, endoscopic and psychiatric-neurological examinations were carried out in 169 cases of peptic ulcer of the stomach or duodenum. Low-voltage and abnormal records were associated usually with larger ulcers of the stomach or duodenum. These abnormalities were significantly more frequent in cases of duodenal ulcer than in stomach ulcer, and were characteristic fora cases with symptoms of neurosis. EEG changes are due, according to the authors, to coexistent emotional disturbances or neurosis.

The effect of metiamide on reserpine-induced gastric ulcers and on gastric secretion during 6 h after ip administration was investigated in conscious intact rats and in rats with chronic gastric fistula. Reserpine, 3 mg/kg ip increased substantially the concentration of gastric acid in the first 4 h. Metiamide given every 3 h in a low dose (0.01 mumol/kg) intensified reserpine-induced gastric ulcers and also significantly increased the reserpine-induced acid concentration and output. In larger doses, (50-100 mumol/kg) metiamide considerably diminished gastric ulcer development and decreased gastric acid concentration. Given every 2 h metiamide in doses of 50-100 mumol/kg almost completely abolished gastric ulcer formation and markedly reduced the secretion of gastric acid in reserpinized rats. Anti-ulcer effect of metiamide was stronger than its antisecretory action, suggesting also the antiulcer action of metiamide other than inhibition of acid secretion. The results suggest that in conscious rats histamine H2-receptors are involved in reserpine-induced gastric ulcer development and gastric acid secretion. The antiulcer effect of metiamide may in part depend on its antisecretory action.
