Thiamphenicol, rifampicin, amantadine, cytosine arabinoside and isoprinosine were administered to mice which were inoculated with brain tissue containing Creutzfeldt-Jakob disease (CJD). All the mice developed disease within 3 to 6 months after inoculation. As there was no significant shift in incubation periods among animal groups of each drug administration and non-administration, these compo...

Most therapies for elderly patients with myelodysplastic syndromes offer few short responses and little improvement in survival. We describe two patients who, after several cycles of low dose cytosine arabinoside and GM-CSF, achieved and maintained complete remission and became transfusion independent. Previous chromosomal abnormalities also disappeared and karyotype remains normal.

Specific interventions included in the review Various adjuvant treatments including chemotherapy, radiotherapy alone or in combination with chemotherapy, and chemoimmunotherapy. The drugs studied were: thiotepa, 5-fluorodeoxyuridine, mitomycin C, 5-fluorouracil, adriamycin, vincristine, cyclophosphamide, methyl CCNU, vinblastine, 1,3-bis(2 chlorethyl)-1-nitrosourea, tegafur, cytosine arabinosid...

A better understanding of the mechanism of chromosomal aberration formation could be obtained by using DNA repair inhibitors. Immortalized normal human (MRC 5 SVI) and ataxia telangiectasia ( AT 5 BIV A ) fibroblastic cell lines were treated with adenosine arabinoside (ara-A) and cytosine arabinoside (ara-C), both potent inhibitors of DNA dsb repair, alone or in combination with x-rays at ...

Nine patients with acute lymphoblastic leukaemia in relapse were treated with a course of cytosine arabinoside followed immediately by a course of L-asparaginase. Eight patients achieved complete remission of their disease. This combination of drugs is sufficiently effective to suggest that further trial is needed. It is possible that the combination has a synergistic effect.

The review provides an update of drug-induced pulmonary disorders, focusing on newer agents whose effects on the lung have been studied recently. Included among these drugs are cyclosporine, cytosine arabinoside (Ara-C), amiodarone, interleukin-2 (IL-2), OKT3, tricyclic antidepressants, and bromocriptine. A brief review of the most common cytotoxic and noncytotoxic agents causing pulmonary toxi...

The Southeastern Cancer Study Group conducted a post-remission induction randomized trial in adult acute myelogenous leukemia to assess the efficacy of alternate drug therapy during consolidation and of immunotherapy during maintenance. Of 508 evaluable patients entered into the study, 335 (66%) achieved a complete remission treated with a 7-day infusion of cytosine arabinoside at a dose of 100...
