[Chemotherapy of chronic myelogenous leukemia in blastic crisis--vindesine, cytosine arabinoside prednisolone combination therapy].

Twenty patients with chronic myelogenous leukemia in terminal transformation were treated with regimen incorporating vindesine, prednisolone and additional cytosine arabinoside. Of the 19 patients in blastic crisis, complete remission was achieved in 13 (68.4%). All four patients with lymphoid morphology, and nine of the eleven patients with myeloid morphology, achieved complete remission (81.8%); the four with monocytoid morphology did not. One patient in accelerated phase also attained complete remission. The present results indicate that the regimen incorporating vindesine-cytosine arabinoside-prednisolone should be treatment of choice in CML-BC with lymphoid morphology and myeloid morphology as well.

Collective Thomson scattering of a high power electron cyclotron resonance heating beam in LHD (invited).

Collective Thomson scattering (CTS) system has been constructed at LHD making use of the high power electron cyclotron resonance heating (ECRH) system in Large Helical Device (LHD). The necessary features for CTS, high power probing beams and receiving beams, both with well defined Gaussian profile and with the fine controllability, are endowed in the ECRH system. The 32 channel radiometer with sharp notch filter at the front end is attached to the ECRH system transmission line as a CTS receiver. The validation of the CTS signal is performed by scanning the scattering volume. A new method to separate the CTS signal from background electron cyclotron emission is developed and applied to derive the bulk and high energy ion components for several combinations of neutral beam heated plasmas.
