<prompt> In acute inflammation due to the contraction of endothelial cell cytoskeleton, which of the following resultsDelayed transient increase in permeabilityDelayed permanent increaseEarly permanent increaseEarly transient increase  <response>: Since the two major mechanisms of host defence against microbes i.e. antibodies and leucocytes are normally carried in the bloodstream, it is not surprising that vascular phenomenon plays a major role in acute inflammation Normally, plasma proteins and circulating cells are sequestered inside the vessels and move in the direction of flow.In inflammation, blood vessels undergo a series of changes that are designed to maximize the movement of plasma proteins and circulating cells out of the circulation and into the site of injury or infection.Changes in vesselThe changes occur in the following orderi Vasodilatation - the Earliest manifestation of acute inflammation sometimes it follows a transient constriction of arterioles.ii. Vasodilation is quickly followed by increased permeability of the microvasculature.iii. Stasis - Increased vascular permeability The hallmark of acute inflammation is increased vascular permeability Acute inflammation has three major steps: -
