Test for the effects of diagnostic levels of ultrasound on the immune response of mice

Abstract An attempt has been made to replicate an experiment which reported suppression of the immune response of mice after exposure of the spleen to a pulsed diagnostic ultrasound unit with a temporal average acoustic power of 8 mW. Our tests of both hemagglutinin and hemolysin responses of mice exposed at 8 and 80 mW temporal average powers were not significantly different from controls.
