Constancy of DNA content per nucleus has been resulted from various investigations, while the change of amount of various nuclear proteins and their relations to nuclear volume remain uncertain. The aim of this report was to solve those questions, using the nuclei isolated in citric acid medium from the liver of well-fed or starved quinea pig, and evaluations were made on the mean size of nuclei and on the amount of nuclear protein per nucleus separated into both basic and residual fractions. Obtained results were summarized as follows: The amount of residual protein in nuclei per nucleus and the mean volume of nuclei were lower in starved than in well-fed animals, while the content of basic protein in nuclei per nucleus was not influenced from starvation.
