Question No 16

A 54-year-old male develops a thrombus in his left anterior descending
coronary artery. The area of myocardium supplied by this vessel is irreversibly
injured. The thrombus is destroyed by the infusion of
streptokinase, which is a plasminogen activator, and the injured area is
reperfused. The patient, however, develops an arrhythmia and dies. An
electron microscopic (EM) picture taken of the irreversibly injured
myocardium reveals the presence of large, dark, irregular amorphic densities
within mitochondria, which are referred to as

a. Apoptotic bodies
b. Flocculent densities
c. Myelin figures
d. Psammoma bodies
e. Russell bodies
