[Serum fibrin degradation products in 13 cases of E.P.H. gestosis (author's transl)]. | Intravascular coagulation causes fetal risk, because it produced placental damage in E.P.H. gestosis. F.D.P. values are above the normal range of the third trimester in 11 out of our 13 cases. Fetal risk is revealed by pathological C.T.G. patterns; fetal death occurred in 4 cases. Therefore, high F.D.P. values are cons... | 754,705 | [

Ambulatory and in-hospital continuous recording of sleep state and cardiorespiratory parameters in 'near miss' for the sudden infant death syndrome and control infants. | Electrophysiologic and cardiorespiratory events were studied polygraphically and by ambulatory monitoring in 'near miss' for sudden infant death syndrome (SIDS) and normal control infants 1-4 months old. The data show that 'near miss' babies typically have many apneic periods in their sleep, particularly apneas lasting... | 754,818 | [

Depression of sympathetic preganglionic neurons by clonidine: evidence for stimulation of 5-HT receptors. | In unanesthetized spinal cats, clonidine HCl (5-50 microgram/kg, i.v.) rapidly and markedly depressed excitatory transmission through two spinal pathways to sympathetic preganglionic neurons. Depression through either pathway was dose-dependent and persisted for more than 3 hr but could be rapidly antagonized at any st... | 755,644 | [
