[Histochemical characteristics of the neural apparatus of the bronchi in different states of tonus]. / Gistokhimicheskie osobennosti nervnogo apparata bronkhov pri razlichnom sostoianii ikh tonusa.

Composite histoenzymochemical characteristics of the nervous apparatus of bronchi in vagotomy, desympathetization, histamine shock, and development of pneumonia experimentally and clinically were obtained. The development of bronchospasm under the above effects and in pneumonia was found to be accompanied by decreases in the activity of acetylcholinesterase, the content of noradrenaline, a high content of nucleoproteins, polysaccharides, a high activity of oxidoreductases in different structures of the nervous apparatus of the bronchi. Bronchodilatation was accompanied by a decrease of all the above-mentioned indicators of the status of the nervous apparatus as well as destructive changes in its elements. The condition of production and utilization of the cholinergic and adrenergic mediators is discussed on the basis of the data obtained.
