Effect of increased gastric mucosal histamine on alcohol-induced gastric damage in rats

Abstract

The aim of this study was to determine whether the cytoprotective effect of prostaglandin might be mediated, at least in part, by inhibition of intramucosal histamine release. Intragastric instillation of increasing concentrations of ethanol in 150 mM HCl resulted in increasing lesion scores and increasing histamine release into the gastric content. Pretreatment with 16,16-dimethyl prostaglandin E2 significantly reduced both lesion scores and gastric histamine output. The intragastric instillation of histamine with tracer [14C]histamine either with or after 50% ethanol resulted in significant gastric tissue uptake of histamine and increased acid secretion. However this had no effect on lesion score, protein output or the protective effect of prostaglandin pretreatment. We conclude that the cytoprotective effect of 16,16-dimethyl prostaglandin E2 in the rat is independent of intramucosal histamine release.

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.
