[The regional circulation of the parotid gland in Sjögren's disease]

Morphological methods, rheography and coagulography were used to study regional circulation in the parotid salivary gland (PSG) in 20 patients with the primary dry syndrome (Sjögren's disease). It has been established that in the presence of immune inflammation with the predominance of traits characteristic of delayed-type hypersensitivity, the vascular bed of the PSG undergoes transformation (changes in the tone, elasticity of vessels, blood flow rate, dystonia of resistive and atonia of capacitance microvessels, lymphostasis, and so forth). The changes in regional circulation are not infrequently coupled with a high concentration of fibrinogen and low fibrinolytic activity of the blood tending towards hypercoagulation.
