Early markers of baked milk and egg tolerance in young children with IgE-mediated immediate reactions.

Children with milk and egg allergies have outcomes in which, three-quarters are tolerant to baked forms of the allergenic food. Identifying predictors of tolerance to baked foods for IgE-mediated immediate-type reactions may guide the early introduction of baked allergens to diet and tolerance development. This study explores factors associated with early tolerance to baked foods.

Experimental Model of Cerebral Arterial Air Embolism in Conscious Rats.

In this work, an optimal air supply mode was selected to create a model of cerebral arterial air embolism (CAAE) on conscious male Sprague-Dawley rats (n=49). The efficacy of the selected model (administration of 100 μl/kg of air at a rate of 10 μl/min with an infusion pump) was determined by changes in serum biochemical parameters (cholesterol, alkaline phosphatase, inorganic phosphates, AST, and triglycerides), impaired motor functions in the Rotarod test, and visual assessment of the ischemic foci (staining of frontal sections with 1% triphenyltetrazolium chloride solution) at different terms after AAE. The model of AAE created by us confirmed impairment of coordination and motor function in conscious animals and reproduced the lethal consequences of this condition.

Modeling of Cerebral Ischemic Stroke in Conscious Rats via Arterial Air Embolization.

The etiological factor of cerebral ischemia in the vast majority of cases is vascular embolism. In the present study we investigated embolism caused by atmospheric air bubbles injected into the internal carotid artery of conscious rats. Immediately after embolism modeling, behavioral abnormalities were observed in the animals, and after 24 h, foci of brain damage were detected.
