4. Which sequence of inflammatory events correctly describes the vascular-phase response that
mediates the tissue injury in this patient?

protein-rich fluid
C. Complement C3a/C5a release → platelet D. Prostaglandin E2 release → vasodilation →
aggregation → thrombosis → tissue hypoxia decreased vascular permeability → edema

A 34-year-old man is exposed to carbon tetrachloride (CCl₄) in an industrial accident. Liver function tests
obtained 48 hours later show AST 850 U/L and ALT 920 U/L. A liver biopsy would most likely demonstrate
centrilobular necrosis with lipid peroxidation of cellular membranes.
7. Which biochemical mechanism is most responsible for the hepatocellular injury in this patient?
A. Competitive inhibition of mitochondrial ATP B. Cytochrome P450-mediated conversion to a
synthase leading to energy depletion free radical causing lipid peroxidation

this impaired phase?
