The afferent and efferent connections of the piriform cortex and the endopiriform nucleus in the rat were studied by the method of axonal transport of two fluorescent tracers: Fluoro-Gold and Fluoro-Ruby. The results indicate that both structures possess not only the connections with the olfactory system, but also the reciprocal connections with the limbic system (entorhinal cortex, amygdaloid body), thalamus (mediodorsal and midline nuclei), extrapyramidal system (ventral part of the nucleus accumbens). The topographic differences in the organisation of the association connections between the anterior and posterior parts of the piriform cortex are reported. Additionally, the reciprocal and relatively numerous connections between the endopiriformis nucleus and the piriform cortex may result in their modulatory function, which in some pathological circumstances may have a critical significance in epileptogenesis.

W pracy scharakteryzowano procesy utleniania frakcji naftowych oraz możliwości ich inhibitowania. Za pomocą pomiarów absorpcji światła i mętności badano przebieg starzenia średniego destylatu z hydrokrakingu pozostałości próżniowej. Z kilku zbadanych dodatków, sól cynkowa kwasu dialkiloditiofosforowego okazała się stosunkowo najlepszym stabilizatorem badanej frakcji.

In this work processes of petroleum fractions oxidation and capabilities of their inhibition were characterized. The ageing run of middle distillate from hydrocracking of vacuum residue has investigated with assistance of measurement of absorption light and turbidity. Out of several researched additives zinc salt of dialkyditiophosfate acid has turned out relatively most effective stabilizer of the researched fraction.

 Hereditary sensory and autonomic neuropathy type 2 is a rare disorder caused by recessive mutations in the WNK1/HSN2 gene located on chromosome 12p13.33. Phenotype of the patients is characterized by severe sensory loss affecting all sensory modalities. We report a novel homozygous Lys179fsX182 (HSN2); Lys965fsX968 (WNK1/HSN2) mutation causing an early childhood onset hereditary sensory and autonomic neuropathy type 2, with acromutilations in upper and lower limbs, and autonomic dysfunction. To the best of our knowledge this is the first genetically proven case of hereditary sensory and autonomic neuropathy type 2 originating from East Europe.
