[The mechanism of trophic effects of salivary glands on oral mucosa].

Using standard HPLC method the catecholamines' content in submaxillary salivary glandular tissue and in oral mucous membrane non-stimulated and stimulated by pilocarpine salivary glands during desalivation and saline solution washing has been studied. In stimulated salivary glandular tissue and oral mucous membrane resulted in diminishing of noradrenaline as well. It was concluded that oral mucous membrane gets noradrenaline in period of basal secretion and spends it during stimulated secretion.
