A 7-year-old girl was successfully treated for acute lymphoblastic leukaemia, and remained in remission after treatment had been completed in 3 years. Four months after cessation of treatment, iridocyclitis with hypopyon developed in one eye. Exudate from the anterior chamber contained numerous lymphoblasts. Local radiotherapy led to complete resolution of the ocular lesions, and the patient re...

Both 2',3'-dideoxyadenosine and 2',3'-dideoxyinosine have been shown (Mitsuya, H., and Broder, S. (1987) Nature 325, 773-778) to have in vitro activity against the human immunodeficiency virus-1 (HIV). However, these dideoxynucleosides may be catabolized by human T cells, even when adenosine deaminase is inhibited by deoxycoformycin. To overcome this problem, we have synthesized the 2-fluoro-, ...

Three versions of the E-rosette test, one using untreated sheep erythrocytes at 37 degrees C, another using such cells at 4 degrees C, and a third using sheep erythrocytes treated with S-(2-aminoethyl)isothiouronium bromide hydrobromide (AET), were applied to each of 72 bone marrow specimens from as many unselected patients with untreated acute lymphocytic leukemia (ALL). The same specimens wer...

The occurrence of lymphoblasts in peripheral blood, measured by incorporating tritiated thymidine ([3H]dThd), was studied before, during, and after a Jarisch-Herxheimer reaction in patients with early syphilis. No difference in [3H]dThd incorporation into peripheral white blood cells was found between five patients with syphilis and 19 healthy controls, whereas in 20 cord blood samples [3H]dThd...

Three growth rate experiments involving several sampling points were performed to investigate the previous finding that very low concentrations of HgCl2 inhibit the growth of murine lymphoblasts in vitro. However, results presented here do not confirm this, there being no significant differences between the three independent growth rate experiments.

Second hematologic malignancies occur rarely in patients previously treated for leukemia. This report describes a patient with acute lymphoblastic leukemia who remained in complete remission for 5 yr and then developed chronic myelocytic leukemia (CML). The original lymphoblasts were associated with a partial deletion of chromosome 21, while CML was associated with a classic Philadelphia marker...
