Abstract Biogenic amines are basic nitrogen compounds, which formed due to the decarboxylation of amino acids or/and amination and transformation aldehydes ketones. Histamine is a heterocyclic biogenic amine present in wide range food products, including fish fishery meat their other dairy products beverages. The review summarizes innovative sample preparation methods for extraction histamine f...

objective: pharmacological effects of carvacrol such as its anti-inflammatory activities have been shows. in this study the effects of carvacrol on serum levels of total protein (tp), phospholipase a2 (pla2) and histamine in sensitized guinea pigs was evaluated. materials and methods: sensitized guinea pigs were given drinking water alone (group s), drinking water containing three concentration...

Restraint-induced stress (RS) increases histamine concentration in the brain. There is no previous report regarding the role of histamine receptors in immunomodulatory effect of RS. In the present study the role of brain histamine receptors on reduction of humoral and cellular immune function induced by RS was evaluated. For this purpose male Wistar rats (200-250 g) were immunized with sheep re...

BACKGROUND: Brain monoamines (such as histamine and dopamine) play an important role in emotions, cognition, reward and feeding behavior. The interactions between histamine and dopamine were studied in many physiological functions but this correlation is unclear in feeding behavior of chickens. The aim of this study was to investigate the interaction of central histaminergic and dopaminergic sy...

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. inflammator...

Introduction: Febrile seizures are the most common seizure disorder in childhood and its prevalence is estimated to be 2 to 5 percent. There is a relationship between the use of corticosteroids and seizures. This study investigated the effects of dexamethasone pretreatment on convulsive behavior caused by hyperthermia. Methods: In this study, 24 rats aged 19-20 days were divided into 3 group...

Background and Aims: One of the neurotransmitters in the brain is Histamine which acts as several biological mechanism regulators like inflammation, gastric acid secretion, and neuromodulation. Inactivation of Histamine occurs by histamine N-methyltransferase (HNMT) enzyme. The HNMT transfers a methyl group from S-adenosyl-L-methionine to Histamine and is the main process for the termination of...

Background: Histamine is an essential biogenic amine produced as a result of microbial decomposition of histidine during seafood processing and storage. The objective of this study was to evaluate histamine concentration in freshwater and marine fish marketed in Stara Zagora region, Bulgaria. Methods: Forty fish samples were purchased from local fish farms and retail stores in Stara Zagora, Bu...
