[Standardization of liver dimensions for the local population]. / Prilog standardizaciji dimenzija jetre domace populacije.

A retrospective and consecutive analysis of the autopsy records for a statistical group of 298 cases revealed 138 pathohistological states of cyanopathies and liver steatoses of the first and second degree i.e. liver conditions which scarcely disturb the dimensions and weight of the liver. Statistical processing of the exactly monitored parameters (length, thickness, height and weight) of the liver in 109 males and 78 females point to a homogenous group of cases without statistically significant differences between male and female subjects. The average liver length in males of the regional population is 26 cm, while in females it is 25 cm, average liver thickness in males of the regional population is 22 cm and 21 cm in females, and the average liver height both in male and female subjects is 7 cm. Average liver weight in males of the regional population is 1700 g and in females it is 1600 g. The values of the established liver parameters can be considered as valid and normal features of the regional population.

[Morphometric analysis of the vascular network of the suprachiasmatic and paraventricular nucleus in the human brain]. / Morfometrijska analiza vaskularne mreze suprahijazmaticnog i paraventrikularnog jedra mozga coveka.

The aim of the study is to discover, the sources of vascularization, vascular areas, the size and density of the capillary network in the suprachiasmatic and the paraventricular nuclei of postnatal human brains of both sexes. The brain blood vessels under examination were filled with a mixture of India ink and gelatin. The serial paraffin sections of 200 microns cleared after Spalteholz. In the vascularization of the suprachiasmatic and the paraventricular nuclei, two arterial stems, take part with their branches (a. cerebri anterior and a. communicans anterior). In order to quantify the density of the capillary network, the authors used the standard stereologic parameters - volume density, surface density and mean radius of blood vessels. The comparative testing of the mean values obtained in male and female subjects did not reveal any significant sex - dependent differences regarding the size and density of the capillary network in the suprachiasmatic and the paraventricular nuclei of the human brain.

[Stereologic analysis of the density of the vascular network of the heart in hypoxia in laboratory rats]. / Stereoloska analiza gustine vaskularne mreze srca laboratorijskog pacova u hipoksiji.

The density of the myocardiac vascular network in 3-month-old female Wistar rats exposed to intermittent hypoxia was studied. The experimental rats were sacrificed immediately (1st experimental subgroup) or 4 days (2nd experimental subgroup) after the last exposition. The volume density was statistically highly significant in the animals of the 1st subgroup and significant in the rats of the 2nd subgroup. The highly significant rise in the volume density of the myocardiac vascular network could be explained by an acute stress effect, whereas the only significant increase in the second case indicates adaptability to stress.
