Effect of human serum thymic factor on immature T lymphocytes in acute leukemia and other hematologic malignancies.

In 37 patients with acute leukemia and in 13 patients with other hematologic malignancies, E-rosette formation of peripheral blood mononuclear cells, before and after incubation with human serum thymic factor, was studied. This assay showed that incubation with thymic factor caused a clear-cut increase of E-rosette-forming cells in 8 of the 37 acute leukemia patients. Among the 13 patients with other hematologic malignancies, a similar effect was observed in two with pediatric Hodgkin's disease and in one adult with Waldenström's macroglobulinemia.

Hair zinc levels in healthy and malnourished children.

In this study the hair zinc levels of 115 healthy subjects, 50 girls and 65 boys, between the age groups 0 to 15 years were determined by using atomic absorption spectrophotometry. The hair zinc levels obtained generally agree with those reported in the literature. The hair zinc levels of the subjects were studied as a function of age, sex and color of hair.

Ultrastructural studies on AMML and ocular granulocytic sarcoma.

The ultrastructural analysis of the leukemic cells in twelve cases with AMML was considered a valuable tool in the diagnosis of this type of leukemia. Furthermore intracytoplasmic structure resembling virus like particles were observed in three bone marrow and one eye sample of the patients studied. The role of C-type RNA viruses in the etiology of leukemia was discussed.

Hodgkin's disease in Turkish children: a clinical and histopathologic analysis.

Fifty-one cases of Hodgkin's disease in Turkish children under 15 years of age were clinically analyzed, and 40 cases were evaluated histopathologically according to the Rye Conference classification. Complete clinical, laboratory, and radiologic findings for each patient were examined. Most patients were of low socioeconomic class, and nearly all were Caucasian.
