Abstract: the study shows pathogenetic mechanisms of formation of bronchial hyperreactivity associated with microelementosis. The study group consisted of 58 children with a combination of atopic dermatitis and bronchial asthma. Methods: inhalation-provocation tests with histamine and metacholine, atomic absorption spectrometry, x-ray fluorescence method. The state of hyperreactivity of the bronchi was accompanied by a deficit of essential microelements (69.6 %) with high sensitivity of the bronchi (PK20 metacholine, histamine-0.125-0.5 mg/ml), against the background of selenium and zinc deficiency (plasma content below 0.2 and 0.35 mg/l, respectively), reducing the speed parameters of the external respiratory

Abstract: it is generally accepted that the barrier-protective function of the tooth as a whole is composed of three levels. Of primary importance is the condition of the surface of the enamel with its organic shells cuticle, pellicle, microbial plaques, etc. Enamel prisms, approaching the tooth surface thickening and forming a smooth and even surface, without any defects. Violation of the integrity of the enamel, the appearance of ultramicroscopic cracks, fractures leads to a significant deterioration of the barrier-protective mechanisms already in the deeper layers, in particular in the dentin. Dentinal tubules, on the enamel-dentinal border and on the side of the predentine and odontoblasts. Defects of the enamel surface serve as a kind of entrance gate and trigger a chain of
