Comparative studies of parasympatholytic drugs on stomach (double blind test) and analysis of relation between gastric form and tonus

N ToheiR Saito


Effects of 3 kinds of parasympatholytic drugs (timepidiumbromide, hyoscine-N-butylbromide and prifinium-bromide) and placebo (physiological saline solution) on the gastrointestinal tract were evaluated roentgenographically by double blind technique in a total of 101 male human subjects. The results may briefly be summarized as follows: 1. There were significant differences on hypotonic rate being one of the indexes of the gastric tonus between timepidium-bromide and placebo. The effects of 3 experimental drugs were significantly high as compared with that of placebo on peristaltic movement of the stomach. The effect of timepidium-bromide was significantly different from that of placebo on the site of arrival of barium. 2. The comparison of degrees of the gastric tonus between main and control tests revealed that the effect of placebo obtained in the main test was significantly inferior to that of hyoscine-N-butylbromide obtained in the control test, whereas there existed no significant differences of the effects among 3 active drugs. 3. Effects of each drug on the gastric tonus which was scored by hypertonic, normotonic and hypotonic state were evaluated by stratification. The result showed that the effect of timepidium-bromide...Continue Reading

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.
