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...

biogenic amines (ba) are nitrogenous compounds that possess biological activity. the source of production is the microbial decarboxylation of amino acids. this compounds are found in various types of cheese. the aim of this work was to evaluate the ba content of some traditional cheeses in west azerbaijan province iran. for this purpose, 70 samples of koopeh, 10 samples of lighvan and 5 samples...

The mechanism of action of some antitumor agents (3-5) has been investigated in recent years by studying their effects in combination with other agents that may be antagonistic or synergistic. Previous work1 in this laboratory showed that the tumor-necrotizing action of the bacterial polysaccharide from Serratia marcescens and of some other tumor-necrotizing agents was reduced by pre-administra...

Histamine is synthesized via histidine decarboxylase (HDC) in wide types of immune cells and is involved in abundant physiologic and pathologic processes. Histamine is a mediator released during inflammatory reactions, such as food allergy. Food allergy is immunological reactions to 'fight off' specific allergens within food in susceptible individuals. The aim of this study is investigation of ...

Histamine intoxication is an important food safety and public health concern. Ripened cheeses are the most common dairy products in which histamine can accumulate. formed by microbiota present cheese decarboxylation of histidine, due to action histidine decarboxylase. This study's objective was identify responsible for formation accumulated commercial cheeses. The content 39 different types mar...

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 ...

On the dog isolated right ventricular muscle, experiments were carried out in order to elucidate the characteristics of the cholinergic antagonism against the positive inotropic action (PIA) induced via different subcellular mechanisms. The relationship between cyclic AMP and cyclic GMP levels, and contractile force during cholinergic antagonism was assessed. Carbachol (10 microM) by itself dec...

Histaminergic drugs have long been used to treat balance disorders in man, but their mechanisms of action in the vestibular system are poorly understood. In this article we review the current literature on histaminergic neurotransmission in the brain focussing particularly in the brainstem vestibular nuclei, and the role of histamine in brain plasticity during "vestibular compensation", the beh...

BACKGROUND Numerous non-steroidal anti-inflammatory drugs (NSAIDs) are commercially available in Spain. This makes proper selection and use of these drugs difficult for GPs. OBJECTIVE To find out the criteria which GPs use to choose among the drugs in this group and to evaluate other criteria related to the clinical management of NSAIDs. METHOD A survey questionnaire was distributed among a...

The histamine releasing potential of equivalent bolus doses of atracurium 0.6 mg kg-1 or vecuronium 0.12 mg kg-1 was evaluated in 20 children anaesthetized with halothane. Blood samples were obtained before, and at 2 and 5 min after the administration of the neuromuscular blocker. The twitch response to 0.15 Hz was also evaluated. None of the 10 patients receiving vecuronium had a significant i...
