title: Laser Doppler microscope in an oblique-backward mode and pulsatile blood flow velocity in pulmonary arteriole.
abstract: Blood flow velocity, pulsatile in correspondence to cardiac events, in pulmonary arterioles of anesthetized bullfrogs could be measured on lung surfaces covered with a water-containing plastic disc by means of a laser Droppler microscope arranged in an oblique-backward mode.
