## Abstract Purified parathyroid hormone (PTH) strongly stimulates the initiation of deoxyribonucleic acid (DNA) synthesis and thereby raises the flow of cells into mitosis in rat thymic lymphocyte populations maintained __in vitro__. These actions of PTH are potentiated by caffeine and inhibited b

Dietary zinc deficiency has been shown to decrease the in vivo incor. poration of thymidine into the nuclear DNA of liver parenchymal cells in the rat. A single injection of 100 pg of zinc was sufficient to rapidly reverse the effect of zinc deficiency on the synthesis of DNA.
## Abstract The role of endogenous regucalcin in the regulation of deoxyribonucleic acid (DNA) synthesis activity in the nuclei of regenerating rat liver after partial hepatectomy was investigated. The addition of regucalcin (0.25 and 0.5 ΞΌM) in the reaction mixture caused a significant decrease in
