[Characteristics of the human lateral geniculate nucleus vascular network]. / Karakteristike vaskularne mreze humanog lateralnog genikulatnog jedra.

The blood supply of the lateral geniculate nucleus (LGN) was studied on ten human brains obtained at autopsy from patients of both sexes with no indication of either psychiatric and neurological disorders or trauma of CNS. The age range was form 30 to 50 years. The brain blood vessels-the basilar artery and the internal carotid artery were injected with a mixture of gelatin and Indian ink. Microdissection revealed that the arterial branches for the LGN arise from anterior choroidal artery and posterior cerebral artery through one of its central branches-lateral posterior choroidal artery. The morphology of arterial network was examined by the analysis of cleared paraffine sections. The arterial branches run in a dorsal to ventral direction of the nucleus, parallely with lines of projection and perpendicularly to the plane of the LGN laminae. Free anastomoses occur between these branches.

[Morphometric analysis of the vascular network in the preoptic area of the brain in man]. / Morfometrijska analiza vaskularne mreze preopticke areje mozga coveka.

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.
