This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Pathology
Contraction of endothelial cytoskeleton in acute inflammation leads to 
Select and explain. 
A. Delayed transient increase in permeability, B. Early transient increase in permeability, C. Delayed permanent increase in permeability, D. Early permanent increase in permeability
B: Early transient increase in permeability
Answer: B: Early transient increase in permeability 
Explanation: Increased vascular permeability is the hallmark of acute inflammation.

Remember

Early transient increase is due to = Endothelial cell contraction
Delayed transient increase in permeability is due to = Direct endothelial injury
Delayed permanent increase Endothelial cell retraction is due to = endothelial cell damage
