[Nitric oxide synthase in neurons of the vagal nucleus dorsalis and ganglion nodosum and its changes following acetylcholine inhalation in the norm and in experimental bronchial asthma]. / Nitrooksidsintaza neironov zadnego iadra i uzlovatogo gangliia bluzhdaiushchego nerva i ee izmeneniia pri ingaliatsiiakh atsetilkholina v norme i pri éksperimental'noi bronkhial'noi astme.

The expression NADPH-diaphorase and inducible NO-synthase (NOS) was studied in vagal nucleus dorsalis and ganglion nodosum neurons following acethylcholine inhalation in healthy rats and rats with ovalbumin-induced experimental bronchial asthma (BA). It was found that NOS activity regulation is mediated by cholinoreceptors; functioning of this mechanism is disturbed in hypoxic state. It is shown that both in conditions of physiological norm and in experimental BA, changes in NOS activity are determined by its constitutive, neuronal isoform.

[The monoaminergic innervation of the mediastinal pleura in human fetuses]. / Monoaminergicheskaia innervatsiia mediastinal'noi plevry plodov cheloveka.

Mediastinal pleura was studied in pregnancy second part abortive human fetuses using histological and histochemical technique. It was found to have a well-developed monoaminergic apparatus that includes adrenergic axons and mast cells. Electron microscope study confirmed monoaminergic and single peptidergic vesicles presence in axons. Luminescent method revealed that mast cells of nerve plexuses and blood vessels contain catecholamines and indolalkylamines. Monoaminergic axons and mast cells were shown to constitute a functionally integrative apparatus that regulates local hemodynamics and trophics.
