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.
The level of neutropenia may vary considerably. In general, the blood of healthy adults contains about 1500 to 7000 neutrophils per mm3 (1.5 - 7.0 x 109 /1). In children under 6 years of age the neutrophil count may be lower.
