Study on the glycoprotein nature of chicken IFNs by chemical cleavage and inhibition of glycosylation.

The considerable molecular heterogeneity of chicken IFNs suggested the possible glycoprotein nature of these IFNs. The carbohydrate-specific oxidation and cleavage by neuraminidase indicated that fibroblast IFN may contain sugar moieties. Among the antimetabolites preventing glycosylation, monensin diminished IFN production.

Examination of the fetal heart with two-dimensional echocardiography.

The methodology of the two-dimensional fetal echocardiography is described by the basic of the accepted international nomenclature. By their opinion it is necessary that on the 18-20th weeks of gestation the high risk pregnants in aspect congenital heart disease examined by well-trained specialists. The indications of the echocardiography are listed, too.

On the nature and molecular basis of prostacyclin induced late cardiac changes.

The late appearing and long-lasting cardiac effects induced by PgI2 or its stable analogue 7-oxo-PgI2 described by us first in 1983 include: 1.) antiischemic, 2.) antiarrhythmic, 3.
