Effects of chlorpheniramine and hydroxyzine administration, as histamine H1- receptor antagonists, on the nociception threshold of cholestatic rats
Introduction: The elevated endogenous opioid tone in cholestasis is associated with changes including an increase in the nociception threshold. We aimed to study the effect of chlorpheniramine and hydroxyzine, H1-receptor antagonists, on modulation of nociception in a model of elevated endogenous opioid tone, cholestasis. Methods: Cholestasis was induced by ligation of main bile duct using ...
متن کاملEffects of intracerebroventricular injection of histamine and H1, H2 receptor antagonists on electrocardiographic parameters in broiler chickens
The aim of this study was to assess the effects of exogenous histamine and H1 and H2 central receptorson electrocardiographic (ECG) parameters, heart rate and mean electrical axis in broiler chickens. For thispurpose, Ross broiler chickens (750-800 g weight) received intracerebroventricularly (ICV) histamine.Moreover, to determine the receptors involved in histamine-induced alterations in ECG c...
متن کاملEffects of administration of histamine and its H1, H2, and H3 receptor antagonists into the primary somatosensory cortex on inflammatory pain in rats
Objective(s): The present study investigated the effects of microinjection of histamine and histamine H1, H2, and H3 receptor antagonists, chlorpheniramine, ranitidine and thioperamide, respectively into the primary somatosensory cortex (PSC) on inflammatory pain. Material and Methods: Two stainless steel guide canulas were bilaterally implanted into the PSC of anaesthetized rats. Inf...
متن کاملInteractions of histamine H1-receptor agonists and antagonists with the human histamine H4-receptor.
The human histamine H(4)-receptor (hH(4)R) possesses high constitutive activity and, like the human H(1)-receptor (hH(1)R), is involved in the pathogenesis of type-I allergic reactions. The study aims were to explore the value of dual H(1)/H(4)R antagonists as antiallergy drugs and to address the question of whether H(1)R ligands bind to hH(4)R. In an acute murine asthma model, the H(1)R antago...
متن کاملInfluence of Histamine H1 Receptor Antagonists on Thioredoxin Production In vitro and In vivo
Background: Thioredoxin (TRX), a 12-kDa oxidoreductase enzyme, is well known to be a redox-active protein that regulates reactive oxidative metabolism. TRX is also accepted to be a protein with anti-inflammatory effects and reported to attenuate the development of allergic airway inflammatory diseases such as allergic rhinitis (AR) and asthma. Although histamine H1 receptor antagonists are freq...
