Treatment with histamine H2 antagonists in acute upper gastrointestinal hemorrhage. Implications of randomized trials.

, 1985
Histamine H2 antagonists are widely used in treating patients with hematemesis and melena, despite the lack of reliable evidence of benefit from any of the randomized trials, considered separately. Examination of the data from all 27 available randomized

A Study of Histamine H2 Antagonists Effect on Survival Rate in Colorectal and Gastric Cancer Patients: A Meta-Analysis

Novelty in Biomedicine
Background: Histamine H2 antagonists (H2RAs) are hypothesized to inhibit suppressor T-lymphocyte function, with preliminary evidence from randomized trials suggesting potential prolongation of survival in patients with operable and inoperable gastric and

Histamine H2-antagonists modify gastric emptying in the rat.

, 1982
1 Histamine H2-receptor antagonists were tested for their effect on gastric emptying in the rat. 2 At low doses all the compounds were inactive except for burimamide which delayed and ranitidine which accelerated gastric emptying.

Rapid desensitization of the histamine H2 receptor on the human monocytic cell line U937

, 1994
In the present study we have subjected the histamine H2 receptor on the monocytic cell line U937 to a thorough pharmacological characterization using a series of selective histamine H1, H2 and H3 receptor agonists and antagonists.

Role and immunomodulatory profile of histamine receptors by H1 and H2 antagonists

, 2008
The present study was designed to delineate the immunomodulatory role of histamine receptors (H1- and H2-) on induction of antibody response to sheep red blood cells (SRBC), as well as the antibody generation profile, in rabbit system, systemically.

, 1984
The effect of cimetidine and two new histamine H2-receptor antagonists, oxmetidine and SKF 93479, on histamine-stimulated adenylate cyclase activity was studied in guinea pig gastric mucosal cells.

On the Specificity of Histamine H₂-Receptor Antagonists in the Rat Cerebral Cortex

, 1975
The effects of iontophoretically applied histamine H2-receptor antagonists and their antagonism of various amines, acetylcholine (ACh), and adenosine 5′-monophosphate (5′-AMP) were studied on spontaneously active rat cerebral cortical neurons. Metiamide
