title: Nuclear particles of non-A, non-B type in healthy volunteers and patients with hepatitis B.
abstract: In an electron microscopic study, nuclear aggregates of virus-like spherical and tubular particles measuring 20 to 29 nm in diameter were found in 5 of 7 clinically healthy volunteers with normal liver histology, 6 of 10 patients with hepatitis B and 17 of 18 patients with hepatitis non-A, non-B. The incidence of hepatocytes containing nuclear particles was approximately 0.5 to 2% in all three groups. We conclude that these nuclear particles are not specific ultrastructural markers of hepatitis non-A, non-B in man as originally claimed for experimental hepatitis non-A, non-B in chimpanzees.
