Is the angiogenic response dependent on ultrasound contrast agent concentration?
This study suggests that [UCA] was a significant parameter in the induction of an angiogenic response with US and UCAs. It also suggests that rather than damage from US and UCAs, as previously speculated, a nondestructive mechanical interaction between the UCAs and vascular endothelium induces bioeffects to potentiate the angiogenic response.
Sputum conversion during the third month of treatment is an important predictor of treatment success; failure to convert predicts treatment failure.
