Hypertension I: Structure of Small Arteries in Hypertension

Thank you for your interesting results, which confirm nicely that the structure of the vasculature can change rapidly.  We found, for example, that in rabbit esophageal vein that there was a doubling of material just four days after induction of portal hypertension (Juhl CO, Jensen LS, Mulvany MJ: Time course development of changes in the structure and reactivity of small veins from portal hypertensive rabbits.  Clin Sci 1989,77:205-211.)

Maybe regression can occur just as quickly?  Incidentally, are you sure that you are observing regression and not failure to develop?
