title: [Modifications of sleep "in utero" in guinea pig after maternal administration of alpha-methyl-L-DOPA (author's transl)].
abstract: Effects of maternal administration of alpha-methyl-L-DOPA on sleep in utero were studied by polygraphic method in Guinea Pig faetus from the 53th day of gestation. Maternal injection of alpha-methyl-L-DOPA (100 and 200 mg/kg) produces a typical sedative effect on the faetus from the first hour after drug administration. But, effects appear attenuated in comparison to those of the new-born Guinea Pig: a paradoxical sleep-deprivation of only 30% is observed during the 12 hours period after drug injection. Causes of the attenuation in utero of these drug effects are discussed.
