Peroxidase and pseudoperoxidase reactions in relation to sudanophilia.

A selective staining of hemoglobin in erythroid cell series was achieved by use of Sudan Black B (modified method of Sheehan and Storey) if optimal amount of hydrogen peroxide was added to the staining mixture. The effect of some inhibitory agents (KCN, wet heat, pH) on this staining as well as on the Lepehne's pseudoperoxidase reaction for hemoglobin was similar. Both reactions were more resistant to these factors than the peroxidase reactions and sudanophilia in granulocytes in which both could be blocked by the pretreatment with absolute methanol. Moreover the effect of some extraction procedures for lipids on both myeloperoxidase reactions and sudanophilia was investigated. The results support the view that the sudanophilia in granulocytes is due to their peroxidase activity and for the staining of hemoglobin by use of Sudan Black B with H2O2 its pseudoperoxidase activity is responsible. In addition the effect of the substitution of phenolphosphate by dihydroxybenzenes on granulocyte sudanophilia is reported.

Sea-blue histiocyte syndrome with bone anomalies.

Two sisters, now 29 and 24 years old, are described. They presented a congenital storage of, most probably, phospholipids in the histiocytes of the sea-blue type or blue pigmentophages. The granules of these cells showed a PAS positivity and strong positivity for acid phosphatase, but there were negative also for non-specific esterase, naphthol-AS-D-chloracetate esterase and iron acid also for urine mucopolysaccharide. The two cases differed from all the described cases in the absence of hepatosplenomegaly and in the presence of bone changes resembling late spondyloepiphyseal dysplasia or atypical dysostosis multiplex.
