[Morphometric analysis of the vascular network in the preoptic area of the brain in man].
Twenty brains of human beings of both sex aged 17-64 were used for morphometric analysis of the vascular network of preoptic area. Blood vessels of the brain were filled by the mixture od India ink and gelatine. Serial resections 200 microns thick were illuminated by the method of Spalteholz. Standard stereologic parameters--volume density, surface density and the average half diameter of blood vessels were used for the quantification of capillary blood network density. By the comparative test of obtained mean values of males and females no statistically significant differences pertaining to sex and in respect to the size and density of capillary network in preoptic area were confirmed. This fact supported the assumption that although there were no morphologic differences in the blood network changes in various functional states, accompanying neuroendocrine events in the body of adults were in all probability the main and responsible factors inducing greater or less vascularization of specific organs.
