The dire wolf (Canis dirus, fearsome dog) is an extinct species of the genus Canis. It is perhaps one of the most famous prehistoric carnivores in North America along with its extinct competitor Smilodon, the sabre-toothed cat.
It is important they remain at adequate levels. As with platelets, neutrophil levels may become depressed in patients on myelosuppressive therapy such as imatinib mesylate (also called IM , Gleevec or Glivec ). The normal range of the percentage of neutrophils is between 45% and 70%. More important than the percentage of neutrophils is the absolute neutrophil count (ANC) , which should fall between 1.0 to 8.0 k/ul.
When the WBC is low, there may not be enough neutrophils to defend against bacterial infections. The white blood cell count is done by counting the number of white blood cells in a sample of blood. A normal WBC is in the range of 4,000 to 11,000 cells per microliter. A low WBC is called leukopenia. A high WBC is termed leukocytosis. A normal absolute neutrophil count (ANC) is in the range of 1,500 to 8,000 cells per microliter. If the ANC is below 500 for an extended period of time, the risk of serious bacterial infection may increase significantly.
