[A comparison of the effect of hydrocortisone and corticosterone on histone and chromatin DNA biosynthesis in regenerating rat liver]. / Sravenie deistviia gidrokortizona i kortikosterone na biosintez gistonov i DNK khromatina regneriruiushchei pecheni krys

Thymidin incorporation into DNA was depressed and glycin incorporation into histone proteins was decreased after the treatment of rats with hydrocortisone and corticosterone for 4 days (for 3 days before and on the day of partial hepatectomy). No significant differences in the action of these glucocorticoids on biosynthesis of DNA and histones in the course of regeneration were noted at the periods under study. There was no decrease in histones and nucleoprotein in comparison with control 6 hours after the operation at the time when the synthesis of DNA-like RNA was elevated. Apparently DNA synthesis was not imperative for biosynthesis of histone proteins, in any way--for the arginine-rich fraction of histones.

[Excretion of estriol in pregnancy complicated by diabetes]. / Ekskretsiia éstriola pri beremennosti oslozhnennoi diabetom

A study was made of estriol excretion in the urine of women during normal pregnancy and in pregnancy against the background of diabetes. It was revealed that estriol secretion was decreased in pregnant women suffering from diabetes. As supposed there existed an interrelationship between the diabetic status and the level of estriol excretion.
