[Varying expression of atherosclerosis in the aortic regions with high and low density of the adrenergic nervous plexuses].

The study was made of early autopsies of 20-55-year-old victims deceased because of trauma. Incubation of sections in 2% glyoxylic acid and luminescent microscopy were used. The density of the adrenergic fibers in the central aortic zones which are most frequently affected with atherosclerosis was 2.8 +/- 0.2%, while in the distal rarely affected zones was 5.0 +/- 0.4%. In the abdominal aorta, the least density (2.1 +/- 2%) of the adrenergic plexuses was over the site of the celiac artery effluence, i.e. at the zones of the intensive atherosclerosis development while the density in the regions slightly affected with atherosclerosis it was 3.8 +/- 0.3%. The results indicate possible permissive role of the sympathetic nervous system in the development of local atherosclerotic alterations.

[Ultrastructure of the sympathetic ganglia in hypoxia].

Short-term hypoxia produces ultrastructural alterations in ganglions of rats in the form of dilatation of some membrane neuron compartments and sinuous plasmatic membrane. More long-term hypoxia produces structural changes of membrane cell components. An increase of lysosome number and lipofuscin granules alternations in chronic hypoxia (1 year) are similar to the age changes and are characterized by intensive accumulation of lipofuscin and Nissl bodies hypertrophy.
