title: [Interstitial gel hydration and its effect on the terminal portions and periacinar blood capillaries of the parotid salivary gland].
abstract: Swelling of the interstitial gel of the parotid salivary gland is modelled by means of perfusing its ducts under various hydrostatic pressure. Connection of this swelling with the size of the terminal secretory portions of the parotid salivary gland and with the size of the lumen in the periacinar blood capillaries is investigated by means of regression equations of the second degree. The size of the terminal portions decreases linearly, while the caliber of the blood capillaries demonstrates a parabolic dependence from the gel volume, when the interstitial gel is swelled. A conclusion is made that the swelled interstitial gel affects the terminal secretory portions of the gland by means of their simple mechanical compression, while the interconnection between the interstitial gel and the periacinar blood capillaries is of a more complicated character and cannot be understand without taking into account certain physico-chemical properties of the interstitial space and changes in intracapillary pressure.
