Does right lung ischemia induce contralateral pulmonary vasculopathy in an animal model?
Pulmonary vasculopathy was absent in the remaining lung 5 weeks after right pneumonectomy but developed in the nonobstructed lung regions 5 weeks after right pulmonary artery ligation, suggesting that factors released by the ischemic lung induced vascular remodeling in the contralateral lung. This endocrine process may involve the release of factors involved in vascular smooth muscle cell proliferation.
It seems that GDPs using a system for digital radiography are more inclined to take radiographs than dentists taking conventional radiographs. Although digital intraoral radiography requires 50-80% less radiation per exposure than film, it is likely that the effective dose reduction after converting from conventional to digital radiography is less than 25% owing to the greater numbers of radiographs taken.
