[Role of IL-8 and defensins in pathogenesis of chronic glomerulonephritis and pyelonephritis].

Aim: The study of interleukine-8 (IL-8) and defensines contribution to pathogenesis of chronic glomerulonephritis (CGN) and pyelonephritis (PN).

Materials And Methods: 122 patients were assigned to three groups: 42 CGN patients with isolated urinary syndrome (group 1); 60 patients with chronic pyelonephritis (CP) with normal nitrogen-excretory function (group 2); 20 patients with CGN and chronic renal failure (CRF) (group 3). 24 healthy volunteers served control.

[Qualitative analysis of the reflection process of three-dimensional objects in neuronal structures of the visual system].

A computer method is proposed for quantitative estimation of correlation between the visual test image parameters and parameters of pattern activity, which arises in neuronal structure as a response to the test image presentation. The method provides a possibility to reduce of systematic experimental measurement errors. It was examined on experimental data, which have been collected by registration of responses cats lateral geniculate body neurons to presentation 2-dimensional pictures of 3-dimensional geometric figures.

[A quantitative assessment of the process of the reflection of the spatial-brightness properties of a stimulus by the neuronal structures in the lateral geniculate body of the cat].

Correlation between spatial brightness distribution in the test image and the spatial response distribution was estimated for the cat LGB. The correlation was found to be quite high. The data obtained corroborate the hypothesis by Podvigin and Kuperman of the topological correspondence of isophote structure family to the pattern of activity reflecting the test image.
