[Arterial hypertension, diabetes and cardiac arrhythmias as risk factor in reversible and completed ischemic stroke].

The aim of the study was to establish the role of arterial hypertension, diabetes and cardiac arrhythmias as the risk factors for ischaemic stroke (IS), considering the type of stroke (RIND and completed stroke) and age. The statistical methods commonly.

[Effect of histological technics on the volume and weight of various brain structures of rats at the early stages of life].

The aim of the studies was to elaborate technical procedure of material preparation for quantitative studies and determination of correction coefficients of morphometric parameters in dependence on histological procedures. Moreover, volume changes of the rat substantia nigra and striatum (structures degenerating in Parkinson's disease) during the first half year of life were estimated. As fixatives 4 and 8% formaldehyde in 4 and 20 degrees C were used.

[Morphological evaluation of tissue and cellular components of the corpus striatum, globus pallidus and substantia nigra in 7-day-old rats].

The aim of the study was the morphometric evaluation of tissue and cell composition of brain structures which are involved into transplantation in experimental model of parkinsonism in the rat-substantia nigra as the implanted structure and caudate-putamen as the host structure into which the graft is placed. Three parts of caudate-putamen (anterior, medial and posterior), three parts of substantia nigra (compact, reticular and lateral) as well as pallidum were investigated in 7-day-old rat. It was found that the density of nerve cells is highest in medial part (2236/l mm2), lower in anterior part (2129/1 mm2) and the lowest in posterior one (1842/1 mm2).
