Examinations
- Tissues and cell types examined:
- Bone marrow cells
- Details of tissue and slide preparation:
- Bone marrow was harvested in pre-warmed Hank's Balanced Salt Solution. Bone marrow cells were treated with a hypotonic solution of potassium chloride in water and is fixed in freshly prepared absolute methanol : glacial acetic acid (3:1).
Fixed cells were dropped onto clean wet slides and allowed to dry. All slides were stained with Giemsa and coverslips applied. - Evaluation criteria:
- For each mouse the following quantities were calculated:
% mitotic cells
Total aberrant cells
% aberrant cells
Total aberrants
frequency of aberrant/cell - Statistics:
