Dielectric Characteristics, Electrical Conductivity and Solvation of Ions in Electrolyte Solutions.

Solvation and association of ions in solutions largely depend on the dielectric properties of the solvent, the distance between ions in solutions, and temperature. This paper considers the effect of temperature on static dielectric constant (DC), dipole dielectric relaxation (DR) time, and limiting (ultimate) high frequency (HF) electrical conductivity (EC) of water and some polar solvents. In the investigated temperature range (0-370 °C), the static DC and DR time of water decrease, and limiting HF EC passes through a maximum at 250-300 °C with temperature growth.

[Immunobiologically active compounds from skin].

This paper describes physiochemical and biological properties of 3 immunologically active compounds extracted by acetone from porcine skin. High pressure gel chromatography confirmed their heterogeneity. RP-HPLC of compound 2 (C2 or K-activin) also characterizes it as a heterogeneous entity.

Some pharmacological properties of immunotropic preparation from porcine skin.

We studied pharmacological properties of immunotropic preparation from porcine skin (skin resorption effect and acute and chronic toxicity). It was demonstrated that the preparation did not damage the skin during evaluation of skin-resorption effect; evaluation of acute and chronic toxicity revealed no changes in the general state of experimental animals and histological structure of visceral organs and skin; evaluation of chronic toxicity showed that the preparation induced no changes in blood biochemical parameters compared to the control.

Immunochemical assay of glia-specific antigens as a criterion for blood-brain barrier permeability in rats during acute intoxication with sodium barbital.

Enzyme immunoassay showed penetration of two glia-specific antigens, glial fibrillar acid protein GFAP and specific brain glycoprotein alpha(2)GP, through the blood-brain barrier in rats treated with toxic doses of sodium barbital. The permeability of the blood-brain barrier was completely normalized 3 days after treatment. This method can be used in clinical practice for evaluation of the severity of impairment and dynamics of normalization of blood-brain barrier properties during acute intoxication with barbiturates.

[The protective action of sodium hypochlorite on the morphology and transcription of the central neurons in rats with acute nembutal poisoning].

NaClO effect on rat central neuron morphology and transcription after injection of high doses (500 mg/kg b.w.) of nembutal (NB) was studied.
