mortality/aging
• increased lethality relative to controls after 7 Gy or more of total body irradiation
• antioxidant N-acetyl-L-cysteine treatment of mice has a protective affect on lethality due to radiation
|
hematopoietic system
• less colony formation using bone marrow cells taken 7 days after 5 Gy of total body irradiation
• bone marrow cells at a competitive disadvantage in repopulating bone marrow of lethally irradiated mice
|
• acute decrease in stem cell numbers 1-10 days after whole body irradiation
• increased apoptosis after whole body irradiation
• increased stem cell proliferation after whole body irradiation and fewer quiescent stage cells
• antioxidant N-acetyl-L-cysteine treatment of mice reduces proliferation
|
homeostasis/metabolism
• increased lethality relative to controls after 7 Gy or more of total body irradiation
• antioxidant N-acetyl-L-cysteine treatment of mice has a protective affect on lethality due to radiation
