The nuclear dry weight of liver cells from patients with virus hepatitis and from controls.
Interferometric investigations were performed at liver cell nuclei isolated in 70 per cent glycerol. In 11 patients with virus hepatitis and seven patients without liver disease the nuclear dry weight of liver cells obtained by liver biopsy was determined by interferometry. The average nuclear dry weight of diploid liver cells from controls was 39.9 pg while an average value of 45.4 pg was found for patients with hepatitis. The corresponding nuclear volumes were 241 and 274mu3 respectively. The dry mass and volume of tetraploid nuclei was twice as big as that of diploid nuclei in both materials. The nuclear water content was neither significantly different between diploid and tetraploid nuclei nor significantly different between nuclei from controls and patients with hepatitis.
