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...

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 ...

background: high levels of histamine and dopamine are found in the hippocampus. furthermore, interaction between histamine and dopaminergic d2 receptors has been demonstrated in the modulation of some behaviors. in the present study, interaction between histamine and dopaminergic d2 receptor in the dorsal hippocampus in the anxiety behavior has been investigated. methods: in this experimental s...

Histamine is a toxic metabolite produced in foods containing high level of free histidine. This compound can be present various food sources, especially seafood, dairy products, and fermented foods. poisoning one the most common health risks caused by consuming spoiled or improper processed stored usually causes mild symptoms with higher recovery rates, so people underestimate this hazard. Thus...

Neurodegenerative diseases contain Multiple Sclerosis (MS), Alzheimer’s disease (AD) and Parkinson’s disease (PD), are characterized by neuronal death and neuronal degeneration in specific regions of the central nervous system (CNS). Microglia are the basic immune brain cells and play a role in homeostasis after inflammation challenge. Microglia involves in Neurodegenerative disease...
