This study aims to explore the role of YKL-40 on permeability vessels in mice model and HDMECs histamine induces vascular hyperpermeability. The expression a HMC-1 was detected by RT-PCR western blot. experiment divided into different concentrations (10, 100 500ng/ml) alone,different concentrations(10, 500 ng/ml) YKL-40+100 μM histamine,500ng/ml YKL-40+100μM histamine+10 loratadine,100 alone bl...

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...

abstract background: it has been demonstrated that noscapine, an antitussive opioid alkaloid, could antagonize bradykinin- induced responses such as bradykinin effects in guinea-pig ileum, cough induced by bradykinin receptor agonist and angiotensin converting enzyme inhibitors, and brain damage after brain edema both in neonatal rat model and in patients with stroke. in the present study, the ...

Introduction: Sensory abnormalities (eg, pain) are common in Parkinson disease (PD) with a negative impact on quality of life. As itch is less studied PD, and pain partially share sensory pathways, we designed this study to identify the occurrence pattern spontaneous itch, responsiveness surrogate model PD. Methods: The protocol was approved (N-20180079) PD patients their best matched controls ...

Anti-inflammatory activity of Indonesian polyherbal product containing Curcuma zanthorrhiza and Vitex trifolia as the main ingredients in carrageenan- histamine-induced inflammation Wistar rats

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 ...

the role of endogenous histamine and h1, h2 and h3 central receptors on food intake in broiler chickenswas investigated. for this purpose, a probe was used to manipulate the concentration of endogenoushistamine by intracerebroventricular (icv) injection of thioperamide, an h3 receptor antagonist, and r-α-methylhistamine, an h3 receptor agonist and subsequently the effects of brain histaminergic...

Purpose: To evaluate the analgesic and anti-inflammatory activities of n-hexane extract of the whole plant of Viola betonicifolia Sm, family: Violaceace. Methods: The n-hexane fraction of Viola betonicifolia (VBHF) was tested for its analgesic and antiinflammatory activities (carrageenan-induced and histamine-induced edema models) in BALB/c mice. Results: VBHF exhibited significant (p < 0.01) a...

Foeniculum vulgare (fennel) has been widely used in traditional medicine for treatment of variousdiseases including pediatric colic. This study was designed to assess the antinociceptive effects of aqueousextract of F. vulgare on visceral pain and possible involvement of opioidergic, serotonergic, adrenergic andhistaminergic systems. The results of this study showed that aqueous extract of F. v...

BACKGROUND Adrenomedullin is a hypotensive peptide recently discovered in human phaeochromocytoma which has been found to inhibit bronchoconstriction induced by histamine and acetylcholine. This study was designed to determine the manner in which adrenomedullin and other bronchodilators interact in modulating airway function. METHODS A study was undertaken to determine whether adrenomedullin ...
