MULTIPLE CHOICE
1. Transmembrane adhesive heterodimeric proteins, composed of an and a ß chain, are
expressed on activated leukocytes during inflammation. They bind primarily to intercellular
adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-1), both of
which belong to the family of proteins known as
a. selectins
b. integrins
c. immunoglobulins
d. lectins
e. growth factors
ANS: C, Surface proteins expressed on activated leukocytes are integrins, and they bind to
intercellular adhesion molecule 1 (ICAM-1) and vascular cell adhesion molecule 1 (VCAM-
1), which belong to the immunoglobulin family of proteins.
2. Which of the following mediators of inflammation has chemotactic properties and is
increased in persons taking aspirin?
a. Thromboxane A2
b. Prostaglandin E2
c. Platelet-activating factor
d. Leukotriene B4
e. Interleukin-1
ANS: D, Leukotriene B4 is chemotactic. It is increased in persons who take aspirin, because
aspirin inhibits the cyclooxygenase pathway, thus shunting more arachidonic acid early
derivatives into the lipoxygenase pathway. This promotes the synthesis of leukotrienes.
3. A 2-year-old child known to suffer from recurrent bacterial infections and poor wound
healing was found to have leukocyte adhesion molecule deficiency 1 (LAD-1). The
leukocytes of this patient do not express CD18, a molecule classified as belonging to the
family of
a. selectins
b. integrins
c. lectin type of vascular adhesion molecules
d. aminotransferases
e. glycosidases

,Test Bank 2-2
ANS: B, LAD-1 is characterized by a deficiency of CD18, a cell surface molecule that is
a ß2 integrin. The infections occur because the defective leukocytes cannot adhere to
endothelial cells, cannot spread and attach, and cannot phagocytose bacteria. PBD7 62
4. Bradykinin is produced from a high-molecular weight kininogen circulating in the blood.
This reaction is mediated by
a. coagulation factor X
b. kallikrein
c. Hageman factor
d. complement C3
e. protein C
ANS: B, Kallikrein promotes the formation of bradykinin from the high-molecular
weight kininogen. PBD7 67
5. Nitric oxide synthesis is augmented in endothelial cells by a calmodulin-mediated influx
of which element?
a. Calcium
b. Sodium
c. Potassium
d. Oxygen
e. Nitrate
ANS: A, Endothelial cell nitric oxide synthase is constitutively expressed at low levels,
but it can be increased by a calmodulin-mediated influx of calcium into the endothelial
cells. PBD7 72
6. Which of the following mediators of inflammation causes pain?
a. Nitric oxide
b. Complement C3a
c. Bradykinin
d. Leukotriene B4
e. Interleukin-1
ANS: C, Bradykinin causes pain. Other pain-causing substances are substance P and
prostaglandin E2. PBD7 65
7. Aspirin lowers the body temperature by inhibiting the synthesis of which regulator of the
central thermostat in the hypothalamus?
a. Leukotriene B4
b. Lipoxin
c. Thromboxane A2
d. Prostacyclin
e. Prostaglandin E2
ANS: E, Aspirin inhibits the action of cyclooxygenase, and thus inhibits the synthesis of

thromboxane A2, prostacyclin, and prostaglandin E2. However, only prostaglandin E2 is
involved in thermoregulation. The synthesis of lipoxin and leukotrienes is not inhibited
by aspirin. PBD7 70
8. C-reactive protein binds to the surface of microbes in tissues acting as a(n)
a. caspase
b. peroxidase
c. opsonin
d. anaphylatoxin
e. membrane attack protein
ANS: C, C-reactive protein, an acute phase protein produced by the liver in acute and
chronic inflammation, binds to microbes acting as an opsonin. Opsonization of bacteria
facilitates phagocytosis.
9. Fibrillin is important for the scaffolding and deposition of which other component of the
extracellular matrix?
a. Collagen type I
b. Collagen type III
c. Elastic fibers
d. Fibronectin
e. Laminin
ANS: C, Fibrillin, a 350 kD glycoprotein, is part of the microfibrils that are important
for the scaffolding and deposition of elastic fibers. A congenital defect of fibrillin, as
seen in patients with Marfan syndrome, is associated with reduced elasticity of arteries
and formation of aneurysms.
10. Which growth factor is the most potent promotor of angiogenesis in the granulation
tissue?
a. Angiotensin
b. Platelet-derived growth factor
c. Tumor growth factor ß
d. Vascular endothelial growth factor
e. Epidermal growth factor
ANS: D, Vascular endothelial growth factor (VEGF) is the most important promotor of
angiogenesis in the granulation tissue.
11. A 20-year-old woman suffered extensive burns and developed large irregular scars over
her hands. These scars limited the movement of her fingers, and she was unable to fully
extend them. What are these lesions called?
a. Contractures
b. Desmoids
c. Aggressive fibromatoses
d. Keloids
