Trinitrotoluene (TNT) and Heinz bodies in Erythrocytes of Frog and Cock

Membrane protein lesions in erythrocytes with Heinz bodies.

We studied Heinz body-containing erythrocytes with three different unstable hemoglobins: Nottingham, Brockton, and unclassified. We demonstrated two classes of membrane protein defects in unstable hemoglobin-containing cells (UH-RBCs), a defect of the spectrin-depleted inside-out vesicle (UH-IOV), and a defect of spectrin (UH-spectrin) itself. The composition of UH-IOVs is the same as control w...

Mineralization of 2,4,6-Trinitrotoluene (TNT) in Coastal Waters and Sediments

Phenyldiimide, hemoglobin, and Heinz bodies.

Phenylhydrazine is oxidized stoichiometrically by two equivalents of ferricyanide to produce phenyldiimide and ferrocyanide. This reaction permits accurate determination of the absorption maxima and molar absorption coefficients of phenyldiimide in aqueous solution. These values are identical or extremely similar to those of phenyldiimide produced by decarboxylation of phenylazoformic acid. Kno...

Heinz bodies induce clustering of band 3, glycophorin, and ankyrin in sickle cell erythrocytes.

In earlier model studies we demonstrated that artificially denatured hemoglobin binds to and clusters the protein, band 3, in the plane of the erythrocyte membrane. To determine whether denatured hemoglobin also clusters band 3 in vivo, we have compared the locations of denatured hemoglobin aggregates (Heinz bodies) with band 3 in sickle cells using phase contrast and immunofluorescence microsc...
