摘要:

Alterations of glycoproteins prepared from the glandular (pyloric) and membranous (rumenal) parts of the stomach wall of rats have been studied polarographically, in comparison with occurance of gastric ulceration and with secretory responses, during gastric ulceration by pyloric ligation. The volume of gastric secretion and the number of ulcer occurance were found to increase in period of 7–24 h after pyloric ligation; meanwhile no increase of HCl secretion was found in that time period. The significant increase of glycoproteins in both parts of the stomach wall was found to be present in period of 0–7 h, and also of 7–24 h, after pyloric fixation. Alterations of glycoproteins are greater and appear sooner after pyloric ligation, but before occurance of gastric ulceration, in the rumenal part of the stomach wall than in the glandular one. The interrelationship was discussed between the ulcer occurance and increase of glycoproteins prepared from glandular and membranous parts of the stomach wall of rats during development of gastric ulceration by pyloric lig

摘要:

An epidemiological study of duodenal ulcer in Israel, based on 763 hospital admissions, is reported. Hospitalized patients, comprise a selected patient population (since not all duodenal ulcer are hospitalized) so that it is impossible to extrapolate from the presented data any conclusions about the frequency of the disease in the generalpopulation. Special features revealed by our analysis were the varying female/male (F/M) ratio with age of onset, ethnic group, profession and marital status. Some socio-cultural aspects are discussed in relation to their importancewith regard to the prevalence and incidence of the disease.

摘要:

A statistical analysis of the acute pancreatitis – cases for the period of 1955–1969 – establishes an anomalous age relationship. For all ages below as well as above 50 years, the rate of incidence remains independent of age, there being a sudden, very significant increase (2–3 times) over the age of 50. No sex-linked differences have been found. It is shown that all cases for which the diagnosis – acute haemorrhagic pancreatitis – was established at the time of exploration and or at the time of necropsy belong to the upper age group B. It is suggested that some sudden involutory changes might be taking place in the pancreas at about th

摘要:

Pentagastrin (0.2–6.4 μg/kg s.c.) given to conscious dogs supplied with a gastric fistula, caused a log dose-dependent gastric secretion of volume, H+, Na+, K+, Ca++, Mg++ and Cl-. The pepsin output was at a similar level as after histamine, but much lower than after insulin-induced vagal stimulation. Atropine methyl nitrate (5 μg/kg i.v.) diminished the secretory response to pentagastrin; dihydroergotamine (40 μg/kg i.v.) augmented the pentagastrin-induced secretion. The significance of pepsin as parameter of the relative tone in the parasympathetic as well as in the sympathetic nervous system is emphas

摘要:

In 27 normal subjects, the effect of secretin on insulin release was determined with 3 doses of this hormone so that the highest dose was almost maximal for pancreatic exocrine bicarbonate secretion. Secretin given alone did not increase insulinemia even at the highest dose, but it potentiated the effect of glucose at a dose that is less than maximal. This result supports the view that secretin may play a role on endocrine pancreas in physiological conditions.
