Prophylaxis of anaphylactoid reactions to a polypeptidal plasma substitute by H1- plus H2-receptor antagonists: synopsis of three randomized controlled trials [PDF]

, 1982
To demonstrate the efficacy of a premedication with H1- + H2-receptor antagonists against histamine-release responses in anaesthesia and surgery 3 randomized controlled trials were conducted in patients, volunteers and experimental animals (dogs ...

The Protective Effect of H2-Receptor Activation Against the Duration of Myocardial Hypoxia/Reoxygenation-Induced Ventricular Fibrillation in Sensitized Guinea-Pig Hearts

Journal of Pharmacological Sciences, 2005
Patients with high serum immunoglobulin E levels were reported to be protected against sudden death during acute myocardial infarction. The protection mechanism might be attributed to the facilitation of histamine release from sensitized mast cells ...

Are hypotension and rash after atracurium really caused by histamine release? [PDF]

, 1994
A prospective, randomized, double-blind study was performed in 40 patients (ASA class I-III) treated with atracurium to ascertain whether histamine release caused hemodynamic or cutaneous changes.

Incidence and clinical importance of perioperative histamine release: randomised study of volume loading and antihistamines after induction of anaesthesia [PDF]

, 1994
Although histamine release is recognised as a common event during anaesthesia and surgery, few clinicians judge the resultant cardiorespiratory disturbances serious enough to warrant prophylaxis with antihistamines.

Effects of Histamine and H1- and H2-Receptor Blocker on Food Intake, Food Passage Rate and in situ Nutrient Uptake from the Small Intestine of Chicken (Gallus domestics)

The Journal of Poultry Science, 2007
To implicate histamine and its receptors in feed intake and nutrient transport, White Leghorn cockerels of the same age and body weight were grouped randomly into six groups.

Perioperative uses of histamine antagonists [PDF]

, 1990
Histamine release and adverse pseudoallergic/allergic reactions during the perioperative period occur frequently. The incidence of such reactions is 20%-30% for all grades of severity, 1%-5% for systemic reactions, and 0.1%-0.5% for life-threatening ...

Histamine H2 Receptor Trafficking: Role of Arrestin, Dynamin, and Clathrin in Histamine H2 Receptor Internalization

Molecular Pharmacology, 2008
Agonist-induced internalization of G protein-coupled receptors (GPCRs) has been implicated in receptor desensitization, resensitization, and down-regulation. In the present study, we sought to establish whether the histamine H2 receptor (H2r) agonist amthamine, besides promoting receptor desensitization, induced H2r internalization.

Plasticity of histamine H3 receptor expression and binding in the vestibular nuclei after labyrinthectomy in rat [PDF]

, 2004
Background: In rat, deafferentation of one labyrinth (unilateral labyrinthectomy) results in a characteristic syndrome of ocular and motor postural disorders (e.g., barrel rotation, circling behavior, and spontaneous nystagmus). Behavioral recovery (e.g.,
