title: Niemann-Pick disease experimental model: sphingomyelinase reduction induced by AY-9944.
abstract: Organs of rats treated with the drug A Y-9944 for 5 days showed a significant reduction in sphingomyelinase activity. Evidence is presented which suggests that the reduction is due to impaired enzyme synthesis.
