[Dynamic effects of crown and spark pulse categories on metabolic processes of blood of rats].

In work it is investigated influences of pulse categories on a metabolism of not purebred rats in dynamics. Research spent to the first day, through six, in twelve day after influence. It is shown, that category crown 5 of impulses and spark's category 100 of impulses, cause increase oxidations lipids for the sixth day and decrease oxidations lipids in plasma of blood and erythrocytes by twelfth day after influence. Influence category crown 50 of impulses and spark category 300 of impulses leads to increase of a level oxidations lipids on membranes erythrocytes. Categories crown 5 and 50 impulses cause dynamic changes of resistance erythrocytes. Decrease in stability for the sixth day and increase of stability erythrocytes by twelfth day after influence categorys crown is shown by pulse categories.

[Distribution of biological particles in two-phase systems of water soluble polymers and salts]. / Raspedelenie biologicheskikh chastits v dvukhfaznykh sistemakh vodorastvorimykh polimerov i solei.

The paper discusses the problems of purification of Provachek's rickettsias used to prepare typhus vaccines and diagnostic kits. The currently available agents contain many admixtures of rickettsias products, more commonly yolk and chick embryo yolk sack cell detritus, which make it impossible to determine the true antigenic properties of rickettsias in the context of protection and diagnosis. By applying the well-known principle of distribution of biological particles in the two-phase systems of water soluble polymers, investigations were made to examine the distribution of rickettsias and their infected biological mass in the system: polyethylene glycol-6600, sodium-500 dextran sulfate, potassium phosphate, sodium chloride in order to prepare agents of pure rickettsias. It has been found that rickettsias are distributed in the polymer-enriched phase, their number and the degree of purity when isolated from the infected biological mass depends on the capacity of an interphase wherein tissue detritus sorption occurs.
