摘要:

A rapid pull-through technique was used to measure lower oesophageal sphincter pressure before and immediately after swallowing. Often no high pressure zone could be detected after a swallow although sometimes an attenuated pressure profile persisted, associated with weakly developed peristalsis. The persistence of normal sphincter profiles was associated with failure of peristalsis or weak peristaltic pressure waves. Overall, there was a significant drop in mean sphincter pressure after swallowing.

摘要:

Intestinal transit times and daily stool weights were measured in 14 residents of Athens and 22 residents of a small village of Greece. Subjects in rural Greece have significantly shorter transit times (38.4 vs. 56.8 h) and heavier daily stools (172 vs. 131 g) than those living in Athens. These findings may be attributable to the more refined diet of the urban Greek population and may explain the different incidence of certain bowel diseases in the urban and rural population of Greece.

摘要:

The influence of cimetidine on the lower esophageal sphincter, the intragastric pH and the serum levels of immunoreactive gastrin was investigated in eight volunteers and compared with a control group. After oral application of 400 mg cimetidine, the intragastric pH rose from 1.7 ± 0.13 to 6.2 ± 0.4 and the lower esophageal sphincter pressure increased slightly but significantly from 15.6 ± 1.1 to 22.7 ± 1.8 mm Hg after 20 min and to 25.8 ± 2.0 after 30 min, respectively. At the same time the serum immunoreactive gastrin levels did not change. A direct effect of cimetidine on the lower esophageal sphincter or an indirect effect via gastric alkalinization is discu

摘要:

The effect of maximal doses of cholecystokinin and caerulein on lipase and chymotrypsin concentrations were compared in large groups of patients with almost equal capacities of bicarbonate secretion. The responsiveness of the pancreas is, as a whole, higher with caerulein than with cholecystokinin, this feature being specially evident in patients with chronic calcifying pancreatitis.

摘要:

Pancreatic function tests were performed before and after dietary therapy in four patients suffering from primitive malnutrition. Maximal bicarbonate concentrations and lipase activity were the parameters most clearly affected by malnutrition and those showing the fastest recovery following therapy. With reference to this quick recovery it seems unlikely that, at least in Western countries, malnutrition could be a cause of chronic pancreatitis. Interpretation of pancreatic function tests requires an exact knowledge of the nutritional status.
