[Morphofunctional analysis of the microcirculatory bed following sublethal dehydration of rats].
Sublethal dehydration is followed by a considerable weight loss, drop in rectal temperature, decreasing respiratory rate, increasing tachycardia and hematocrit. Sublethal stages of dehydration result in uniform changes in the dura mater, parietal peritoneum, small intestine mesentery, muscular part of the diaphragm, the renal capsule deformation, discomplexation of microvessel networks and structural changes of microvessel walls. Microvessel morphometry has demonstrated a certain decrease in diameters of all the parts in the objects studied. Maximal decrease of the diameter has been noted in capillary and postcapillary venular parts. The greatest changes in microvessel structure has been noted in the dura mater and in the serous sheets.
