Objective: Crocin, as an active constituent of saffron, has many biological functions including antioxidant and anti-inflammatory activities. The present study was aimed to investigate the effects of crocin and chlorpheniramine on local edema induced by histamine. Materials and Methods: Local edema was induced by subcutaneous injection of histamine (100 μl, 0.1%) in ventral surface of right hi...

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...

In this study, the effects of separate and combined intraperitoneal (IP) injections of histidine and dexamethasone were investigated on local inflammation in rats. Local inflammation was induced by subcutaneous (SC) injection of histamine (100 μl, 0.1%) in ventral surface of right hind paw. The thickness of paw was measured at 30 min before and 30, 60, 90, 120, 150 and 180 min after injection o...

Several evidences have indicated that many nuclei in the brain have critical role in water intake. Angiotensin II is one of the most important neurotransmitters involved in regulation of fluid homeostasis. In this study, the interaction of i.c.v. injection of captopril and histamine on water intake in adult male water-deprived rats was investigated. Rats were implanted with guide cannula aimed ...

In a previous study, the relaxant and anticholinergic (functional antagonism) effects of Bunium persicum (B. persicum ) have been demonstrated on guinea pig tracheal chains. To elucidate the other mechanisms responsible for this relaxant effect, the inhibitory effect of this plant on histamine H1 receptors was examined in this study. The antihistaminic effects of aqueous and macerated extracts,...

introduction: the protective and antisecretory effects of dopamine agonists on the stomach have been already reported, but the effect of bromocriptine (d2 dopamine agonist) on histamine stimulated gastric acid secretion (gas) needs to be investigated. methods: for gastric sampling, animals were anesthetized and a polyethylen tube was introduced into the stomach through esophagus. a cannula was ...

Histamine, which is a naturally occurring chemical in seafood, known to cause undesirable inflammatory response when consumed large amounts. Histamine produced unsafe amounts colored seafood improperly stored for just few hours. Food and health regulatory bodies across the world have guidelines limiting amount of histamine fresh as well processed seafood. Conventional detection performed testin...

Histamine intolerance is defined as a disequilibrium of accumulated histamine and the capacity for degradation. This clinical term addresses non-immunologically mediated pathology when ingested with food not particularly high, however its degradation decreased. paper aims to provide narrative review on etiopathology, epidemiology, possible diagnostic algorithms challenges in children. The pictu...
