Abstract

1. Gastric acid responses to the test meals were measured in the Heidenhain pouch, gastric and pancreatic fistula dogs, using the intragastric titration method, and monitoring the rate at which a solution of 1-0 N-NaOH had to be added to maintain the pH of the gastric content constant at pre-selected values ranging from 5-0 to 1-0. In this way the pH profile of the gastric acid and pepsin responses to a liver extract meal kept in the Heidenhain pouch or gastric fistula as well as to exogenous stimuli such as histamine, pentagastrin or Urecholine could be determined. 2. A liver extract meal adjusted to pH 5-0 produced a potent and pressure-related stimulation of acid secretion from the Heidenhain pouch without any change in secretion from the main stomach and pancreas or in the serum concentration of immuno-assayable gastrin. 3. Graded decrease of the liver extract meal pH to below 5-0 resulted in the pH-dependent inhibition of gastric acid output, which at pH 1-0 was only about 30% of the value attained at pH 5-0. Acid secretion from the Heidenhain pouch induced by exogenous stimuli such as histamine, pentagastrin or Urecholine also showed gradual decrease when the pH of the pouch content was decreased in sequential order from ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.
