The filter elution technique was used to assay Co-60 g ray-induced DNA single-strand breaks (SSB) in EL 4 mouse leukemia cell and spleen lymphocyte. The lymphocytes were stimulated with lipopolysaccharide (LPS, 20 mug/ml) to label [3H] thymidine. EL 4 cells and lymphocytes in suspension were exposed at 0degree C to gy, 1 gy, 5 gy, 10 gy of Co-60 radiation... |

Mesna has been used with ifosfamide to prevent urotoxicity in the treatment of testicular cancers. This drug also protected the toxicities of adriamycin without compromising cytostatic activity. With n idea of radioprotective role of sulfhydryl group of radioprotectors and of mesna decreasing the toxic effect of adriamycin which produces free radicals, mesna and radiation were administered to mice to study... |

Radiat Oncol J. 1990;8(2):155-162.
-
|
Spiral microwave antennas have been developed and measure the thermal distribution in agar phantom. The design has been configured in three types, 3cm f applicator with 24.5cm length (A type), 4cm f with 12.2cm (B type) and 6cm f with 24.5cm length (C type). The relative specific absorption rate (SAR) measured in phantom have been used to estimate the depth... |
