    Notes: Abstract Increased choroidal pressure and choroidal stasis were induced in Dutch rabbit eyes by tying off vortex veins. Ligating one to three vortex veins caused a progressive diminution in the b- and c-waves of the electroretinogram so that the amplitudes were approximately half of control values when three vortices had been ligated. After ligation of four vortex veins, the responses rapidly disappeared. Release of the occlusion twenty minutes later caused the b-wave to return to normal over a few hours' time, but the c-wave showed variable recovery and was replaced by a large slow pIII response in half of the experiments. These observations may reflect a combination of hypoxia and alterations in fluid movement that affect the status of the subretinal space.

    Notes: Abstract Antibody subclasses directed against the core protein (HCc) of hepatitis C virus (HCV) were measured in 27 patients with acute non-A, non-B (NANB) hepatitis, and 99 patients with chronic HCV-associated liver disease. IgM, IgA, and IgG anti-HCc responses were observed in 11 (40.7%), 7 (25.9%), and 18 (67%) patients with acute NANB hepatitis, respectively. Twenty-four (24.2%) and 40 (40.4%) patients with chronic HCV infection also had detectable IgM and IgA, respectively. IgM anti-HCc inconsistently detected acute infection, and HCV ribonucleic acid (RNA) could be detected preceding the rise in anti-HCc antibodies in five consecutive patients with acute hepatitis. IgM anti-HCc also could not distinguish acute from chronic infection and did not correlate with histologic progression. However, the form of IgA present (polymeric vs monomeric) did discriminate acute from chronic infection and the IgA anti-HCc titer correlated with histologic evidence of liver disease in patients with chronic HCV infection.
