fractional exhaled nitric oxide (feno) has been suggested as a non-invasive biomarker of airway inflammation, which is increased in atopic subjects. whether sensitization to particular allergens is a predictive factor for increased feno levels is not yet fully understood. we conducted a retrospective cross-sectional study. from october to december in 2015, the medical documents of 127 mild, ste...

A single injection of epsilon,DNP-Lys(7-10) can render previously sensitized guinea pigs specifically unreactive to subsequent intradermal challenge with that antigen. Antigen-reactive lymphocytes, as assayed by macrophage-migration in-inhibition or thymidine incorporation, were depleted from the peritoneal exudates of those animals. In contrast, it was intriguing to find that lymph node lympho...

BACKGROUND Morphine and its derivatives are key drugs in pain control. Despite its well-known analgesic properties morphine at high concentrations may be proalgesic. Particularly, short-lasting painful sensations have been reported upon dermal application of morphine. To study a possible involvement of TRP receptors in the pro-nociceptive effects of morphine (0.3 - 10 mM), two models of nocicep...

The influence of stress and diazepam treatment on airway inflammation was investigated in ovalbumin (OVA)-sensitized rats. Animals were injected with OVA plus aluminum hydroxide intraperitoneally (day 0) and boosted with OVA subcutaneously (day 7). From the first to 13th day after sensitization, rats were treated with diazepam, and 1 h later they were placed in a shuttle box where they received...

The cellular basis for delayed-type hypersensitivity was established by the passive transfer of delayed-type reactions to normal guinea pigs by means of lymphoid cells obtained from hypersensitized animals.' Attempts to demonstrate a mediator of delayed-type hypersensitivity in sera or lymphoid cell extracts from sensitized individuals have been unsuccessful in experimental animals.2 Recently a...

High levels of plasminogen activator (PA) were induced in mouse peritoneal macrophages by infection with BCG, 2-6 X 10(7) viable organisms intravenously, followed 3-4 wk later by intraperitoneal challenge with purified protein derivative (PPD) 2 days before harvest. Macrophages obtained from infected animal without boosting showed little fibrinolytic activity, but challenge of Bacille-Calmette-...

OBJECTIVE Asthma is a chronic inflammatory disease of the respiratory airways distinguished by edema and infiltration of inflammatory immune cells. To test our hypothesis about the anti-inflammatory effect of saffron, we examined effects of Crocus sativus (C. sativus) extract as a prophylactic anti-inflammatory agent in sensitized rats. MATERIALS AND METHODS To induce experimental asthma, rat...

objective(s): human and animal studies have shown a close relationship between obesity and asthma severity. here, we examined the effects of diet-induced obesity (dio) on the expression levels of il-1β, irak-1 and traf-6 mrna in male wistar rats tracheal after sensitization with ovalbumin (ova). materials and methods:twenty male wistar rats divided to four groups, included, control group with n...

.a simple spectrofluorimetric method is described for the determination of doxorubicin (dxr) based on its quenching effect on the fluorescence intensity of tb 3+ - deferasirox (dfx) complex as a fluorescent probe. the excitation and emission wavelengths were 328 and 545 nm, respectively. the effects of ph, time, order of addition of reagents, concentrations of tb 3+ and dfx and the buffer volum...

The current studies examined the role of medial prefrontal cortical (mPFC) group II metabotropic glutamate receptors (mGluR2/3) in the development of cocaine sensitization. Initial studies demonstrated that intra-mPFC injection of the mGluR2/3 receptor agonist, APDC, dose-dependently reduced acute behavioral response to cocaine (0.015-15 nmol/side with significant effects starting at 1.5nmol/si...
