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.
Neutrophils are a common type of white blood cell important to fighting off infections â particularly those caused by bacteria. For adults, counts of less than 1,500 neutrophils per microliter of blood are considered to be neutropenia. For children, the cell count indicating neutropenia varies with age. Some people have lower-than-average neutrophil counts, but not an increased risk of infection. In these situations their neutropenia isn't a concern.
