Effects of mechanical loading on early conduction system differentiation in the chick.

The primary ring, a horseshoe-shaped structure situated between the left and right ventricle and connected superiorly to the atrioventricular canal, is the first specialized fast ventricular conduction pathway in the embryonic heart. It has been first defined immunohistochemically and is characterized as a region of slow myocyte proliferation. Recent studies have shown that it participates in spreading the ventricular electrical activation during stages preceding ventricular septation in the mouse, chick, and rat.

[Prevention of recurrence of herpes with poliovaccine].

In the course of 20 years in collaboration with dermatologists and doctors attending adolescents 75 patients were treated suffering for at least four years from 10 relapses of herpes labialis or genitalis every year. The usual treatment mitigated only temporarily their complaints but had no effect on the frequency of relapses. Two thirds of the patients had immunological examinations, in half of them shortage of IgA was found.

[Detection of antibodies to submitochondrial particles, F1-ATPase complex and liver specific lipoprotein in liver diseases using ELISA].

ELISA was elaborated for the determination of antibodies against liver antigen complexes--submitochondrial particles, F1-ATPase and liver specific lipoprotein. The parameters achieved so far allow to use the assay as an undemanding complementary laboratory technique in diagnosing and monitoring hepatopathies of autoimmune origin. Cross reactivity between individual antigen complexes was recorded in the majority of sera from positively reacting patients.
