1. The production of Heinz bodies, after incubation of erythrocytes in the presence of hydrogen peroxide vapour, was significantly greater in erythrocytes with abnormally low glutathione peroxidase (GSH-Px) activity than in cells with normal enzyme activity. 2. The addition of the catalase inhibitor, sodium azide, to the incubation mixture, increased the formation of Heinz bodies after exposure...

We extend the Chern-Heinz inequalities to graphs of C 2-functions defined on open subsets of Riemannian manifolds. We generalize results about foliations of 3-dimensional Riemannian manifolds by constant mean curvature surfaces due to Barbosa-Kenmotsu-Oshikiri [3], Barbosa-Gomes-Silveira [2].

Decreased deformability of acetyldamaged cells, in an all-or-none phenylhydrazine-treated erythrocytes, fashion. In mixtures, separation of unmeasured by in vitro filtration experitreated cells from Heinz body-containments, was found to parallel Heinz ing erythrocytes could be accombody formation. The decreased deplished by filtration. There may be a formability seemed unrelated to merelationsh...

Mutant, unstable hemoglobins precipitate as Heinz bodies in circulating red blood cells resulting in their premature hemolysis. We stress that generally these hemoglobins contain amino acid substitutions in the beta-chain of globin near the heme pocket, and demonstrate that heme binding suffers thereby. Four genetically unstable hemoglobins lost roughly half their heme content while precipitati...
