18
Q

Left Shift

A

Increased concentration of immature neutrophils in the blood

19
Q

Myeloproliferative disorders

A

Neoplasms arising from bone marrow stem cells and involve neutrophils, monocytes, erythrocytes and rarely, eosinophils and basophils

20
Q

Clinical sign of Chediak Higashi Syndrome

A

Sliver to grey coat color due to fusion of melanin granules

Common in persian cats

21
Q

Granulocytic leukemia

A

Neutrophils

22
Q

Causes of eosinophilia

A

Parasitism

Hypersensitivity

Lesions producing eosinophil chemoattractants (Mast Cell Tumor)

23
Q

Leukemia

A

Presence of neoplastic cells in the blood or bone marrow

24
Q

Strees Leukocyte Response can occur with

A

Occurs with illness, pain, metabolic disturbances, treatment with corticosteroids/corticosteroid producing tumors

25
Q

Inflammation Leukocyte Response

A

Consumption of neutrophils in inflammatory response leads to increased production and early release from bone marrow

26
Q

T/F: Bone marrow problems are always reversible

A

False

____________________

FeLV virus infection = irreversible

27
Q

Myelomonocytic Leukemia

A

Neutrophils and monocytes

28
Q

Leukocyte Responses

A

Inflammation

Excitement

Stress

29
Q

Monocytic leukemia

A

monocytes

30
Q

Left shift or neutrophil concentration greater than 2x upper limit of reference interval

A

Neutrophilia

31
Q

Causes of lymphocytosis

A

Excitement Leukocyte Response

Neoplastic Lymphoproliferative Disease

Antigenic Stimulation

32
Q

Philia / cytosis

A

Increased concentration of cells

33
Q

Pelger Huet Anomaly

A

Failure for neutrophil nucleus to segment - continue to look like bands

______________________

Increased immature neutrophil count without any clinical signs

34
Q

Neutrophil hypersementation

A

Result of normal aging of the neutrophil may occur in vivo (longer circulation, use of corticosteroids) or in vitro (aging prior to making film)

35
Q

Erythroleukemia

A

Red cells and neutrophils or monocytes

36
Q

Neutrophilia + Lymphopenia + no left shift

A

Stress Leukocyte Response

37
Q

Acquired lymphocyte vacuolation can occur by

A

Ingestion of plants containing swainsonine which results in inhibition of lysosomal enzymes resulting in acuired lysosomal storage disease

38
Q

Neutropilia with Lymphocytosis and no left shift

A

Excitement Leukocyte Response

39
Q

Lymphoproliferative disorders

A

Neoplasms of lymphocytes and plasma cells

40

42
Q

Orderly maturation

A

Concentration of each cell increases with the degree of maturity

43
Q

All inherited lymphocyte abnormalities except MPS and Acid Lipase Deficiency cause what type of disease

A

Severe Progressive Neurologic Diseas
