The total and HDL-cholesterol levels in populations of St. Petersburg (Russia) and Leipzig (Germany).

Background And Aim: In the early 90s an increase in coronary heart disease (CHD) mortality in post-communist countries was observed. Based on the lipid theory of the pathogenesis of atherosclerosis, we looked to see whether these changes were accompanied by changes in blood lipid profiles and how lipid levels are related in a post-communist country with a relatively high standard of living (East Germany) and a country still facing economic troubles (Russia).

Methods And Results: This investigation was conducted in 1995-1997 by a cooperative program between the Department of Clinical Chemistry and Pathobiochemistry, University of Leipzig, Leipzig, Germany and the Department of Biochemistry, Institute for Experimental Medicine, St.

[Detection of Erysipelothrix rhusiopathiae specific antibodies in the serum of experimentally-infected swine by ELISA and immunoblotting].

In an attempt to characterize the immuno response of the animal organism to experimental infection, ELISA and immunoblotting were used to test the antibody levels of erysipelas hyperimmune sera (HIS) which had been induced by Erysipelothrix rhusiopathiae. Also, 5 pigs were accidentally chosen to check on individual curves of antibody formation, following periodical inoculation up to HIS collection. All HIS verified and confirmed by the mouse protective test responded by high titres.
