نبذة مختصرة : Facial arteries from C57BI/6 mice were isolated and pressurized to 60mmHg before pre-constriction with U46619. (A-C) . Vessels were exposed to 5 minutes of 670nm NIR Light, 10 minutes in darkness with no light, and then a second exposure of NIR light. ( B). Preincubation of facial arteries with TEA (1mM for 10min) resulted in no increase in diameter upon energy exposure (R/NIR). ( C). Preincubation of facial arteries with Paxilline (200nM for 15min) resulted in no increase in vessel diameter upon energy exposure (R/NIR). N = 8 vessels from 4 mice in each group.
