[Morphofunctional analysis of the response of the parotid gland to disruption of its sympathetic innervation].

The parotid salivary gland of rats was studied after extirpation of the upper cervical sympathetic ganglion in different time after a single feeding. The gland of non-fed animals served as control. The desympathization of the gland has been shown to result in considerable alterations in the ultrastructure of its acinar cells and less pronounced alterations in the salivary tube cells. The interferometrical study has shown that after desympathization the dry weight of acinar cells, the sparseness of the dry weight figures in different animals and the amplitude of the protein amount fluctuations during the secretion cycle decreased. The obtained data point out that to sustain the structural entity of the organ and its normal functioning the sympathetic innervation of the organ must be kept intact.
