Recent studies reveal success in treating spinal cord trauma with early, high-dose methylprednisolone. As in spinal cord research, failure to find therapeutic effects with steroids in studies of acute stroke treatment may reflect institution of treat

✓ The authors studied local cerebral blood flow in monkeys rendered hypotensive by infusion of a ganglionic blocking agent. Application of the 14C-antipyrine method demonstrated that the blood flow: 1) normally varies reproducibly from one structur

The amniotic fluid was replaced with 20 per cent sodium chloride solution during the second half of gestation in 12 pregnant rhesus monkeys. This produced a congealing of the fetal blood in the small umbilical vessels which overlie in the placental c

The present study identifies several factors that govern brain pathologic response to marked hypoxia. None of 13 cats exposed to 25 minutes of marked hypoxia (FiO2 = 3.4%; PaO2 = 17 +/- 3 mm Hg, S.D.) that maintained mean arterial blood pressure (MAB

Midgestational sheep fetuses exposed to marked hypoxia for 2 h remain brain intact if MABP is maintained above 30 mm Hg. On the other hand, similarly hypoxic fetuses, if they experience reductions in MABP below 30 mm Hg, develop foci of necrosis that

Twenty-one late-juvenile rhesus monkeys were rendered profoundly hypotensive for 0-, 15-, or 30-minute periods by means of infusion of trimethaphan camsylate. Blood pressure was then restored to prehypotensive levels with phenylephrine infusions. Res

Term monkey fetuses may be subjected to episodes of total asphyxia characterized by complete stoppage of respiratory gas exchange. Such animals, after resuscitation and extended survival, exhibit damage to structures in their brainstems. This injury

The effect of pentobarbital, given to the mother, on maternal and fetal blood gas tensions was examined. Pentobarbital anesthesia reduced the rate of acid accumulation during asphyxia in fetal monkeys, increased the duration of primary apnea and of g

Nine female rhesus monkeys at 118 to 160 days of gestation were infused intravenously with unfiltered autogenous amniotic fluid in quantities up to 5 ml. per kilogram. Changes in maternal cardiovascular performance, respiratory rate, acid-base state,

The relationship between the various components of late decelerations of the fetal heart rate (type II dips) and the pH, P o 2, and hemoglobin saturation with oxygen of the fetal arterial blood was investigated in 15 anesthetized near-term rhesus mon
