A number of carborane-containing porphyrins were administered to mice bearing subcutaneously transplanted mammary carcinomas. Administration was via serial intraperitoneal (i.p.) injections to assess their relative toxicities and tumour affinities. Three analogues of the natural porphyrin heme and four tetraphenylporphyrins (TPPs) were given at total doses(More)
We investigated the effects of murine recombinant interleukin-1 (rIL-1, Du Pont) in vivo in the normal rat brain and here report both local and systemic effects of centrally administered rIL-1. Normal rats were given single or multiple atraumatic doses of either rIL-1 or and equal volume (5 microliters) of vehicle for control comparison. All dosages of(More)
The ventral surface of the tongue of male Fisher 344 rats was used to evaluate the response of oral mucosa to boron neutron capture irradiation. Three hours after i.p. injection of 700 mg/kg of the boron delivery agent p-boronophenylalanine (BPA), the boron concentrations in blood and tongue mucosal epithelium were approximately 21 and 23 microgram (10)B/g,(More)
This study, using the CBA/Ca mouse as a model, compares genetic lesions associated with radiation- and benzene-induced acute leukemias. Specific types of leukemia included in the analyses are radiation-induced acute myeloid leukemia (ML), and benzene-induced lymphoblastic leukemias, lymphomas, or mix-lineage leukemias. These leukemias have histopathological(More)
N-ras mutations were examined in DNA samples extracted from the spleen of CBA/Ca mice that developed myeloid leukemia (ML) following exposure to radiations of different qualities. A total of 17 ML cases, i.e. 5 cases of neutron-induced and 12 cases of photon- (3 gamma-ray and 9 x-ray) induced ML were included in the study along with 12 DNA samples from the(More)
As a follow-on study to the feasibility of neutron capture therapy (NCT) with 235U brachytherapy seeds, physical doses were calculated and measured for the radiation from a 235U foil in a lucite phantom which was irradiated at the epithermal neutron irradiation port of the Brookhaven Medical Research Reactor. In addition, cell survival experiments were(More)
The telomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in radiation-induced mouse myeloid leukemic (ML) cells and in several populations of normal cells. A detectable level of telomerase activity was found in normal hematopoietic tissues, i.e., bone marrow (BM) cells, day 9 colony-forming unit spleen (CFU-S)(More)
