The status of bone marrow cells in different groups. Microscopic view of animal’s bone marrow cells in the groups (trypan blue staining, ×400 magnification). C (the average number of cells is normal (normocytosis)), Ac (cell counts are reduced significantly and cellular toxicity (hypocytosis)), Ac + 100Ex (reduction of the cell counts), Ac + 200Ex (cell counts are increased and change to normocytosis), Ac + 400Ex (cell counts are decreased and cell toxicity), and Ac + NA (cell counts are increased and shift to normocytosis).
