Pathomorphological changes in hyaline cartilage during focal persistent infection.

We studied morphological changes in hyaline cartilages of different localization in adult male rabbits with focal persistent infection produced by Staphylococcus aureus strain 209. Local chronic inflammation produced systemic atrophic and degenerative changes in the cartilage tissue. The severity of pathological changes depended on genetically determined repair and metabolic activity of the cartilage tissue.

[Clinico-immunological comparisons in cerebral arachnoiditis].

106 patients with cerebral arachnoiditis diagnosed according to pneumoencephalographic and computer-tomographic findings were studied. 65 patients had clinical signs of progredient disease (lability and an increase of neurologic symptoms). In 41 patients clinical pattern was stable during several years.

[The pathogenetic mechanisms of the development of experimental allergic polyradiculoneuritis].

Biochemical, immune and morphological changes in peripheral nervous system at different stages of experimental allergic polyradiculoneuritis were studied in 102 rabbits as indicated by total lipids, cholesterol, phospholipids and their fractions, diene conjugates of spinal ganglions, cervical, thoracic and lumbosacral roots, trigeminal ganglions and nerve trunks of extremities. It was found out, that derangement of lipid metabolism in spinal ganglions and nerve roots is the primary phase in the development of the disease. Those could be seen as early as the experiment day 6.
