RELATIONSHIP BETWEEN NUCLEAR VOLUMES, AMOUNT OF INTRANUCLEAR PROTEINS AND DESOXYRIBOSENUCLEIC ACID (DNA) IN VARIOUS RAT CELLS

Cytochemical photometric microscopic determinations of proteins and desoxyribosenucleic acid in cells of rat tissues gave the following results :

1. A direct correlation exists between different sizes of nuclei and amounts of intranuclear proteins in rat liver cells, while the amount of DNA was found to be independent of nuclear size.

2. In the gastric mucosa, where cells with different synthetic activities (parietal and chief cells) occur, there is no parallelism between nuclear size and proteins. The chief cells have a larger amount of protein than parietal cells, while the amount of DNA is the same in both.
