Serotonin levels in the cerebrospinal fluid (CSF) were determined at various time intervals following experimental spinal cord trauma and correlated with alterations in the intramedullary blood flow. At one hour after injury, a significant elevation of CSF serotonin was noted to parallel a marked reduction in white matter perfusion. The correlation between(More)
The status and function of monoamines in experimental spinal cord trauma remains a subject of controversy and continued debate. The norepinephrine hypothesis has been severely weakened by its lack of reproducibility. Dopamine results are too variable to draw meaningful conclusions. The role of serotonin, particularly with reference to its vasoactive(More)
A patient with a dominantly inherited form of Kuf's disease and an associated occipital astrocytoma is presented. This is the first reported case in which the diagnosis of Kufs' disease was made by a cortical biopsy several years before its expected clinical onset. The nosology of this disease, and its clinical, genetic, and histopathological(More)
A research model for intracranial surgery in the primate fetus was developed and tested in 10 timed-pregnant rhesus monkeys. With general anesthesia and sterile surgical technique, a laparotomy followed by a lower uterine segment hysterotomy was performed at a site avoiding the placenta. The amnion was opened carefully by use of the operative microscope and(More)
The feasibility of intracranial surgery in the rat fetus is demonstrated by the use of a microsurgical model. In utero craniotomy and cerebral incision have been performed successfully without compromise of the fetal-maternal unit. Maternal and fetal survival rates of 95 and 93%, respectively, are reported. Several principles of fetal surgery have been(More)
The effect of alcohol on the injured spinal cord in cats is assessed by use of a standardized trauma model at both nonparaplegic and paraplegic trauma forces. Prior administration of an intoxicant dose of ethyl alcohol resulted in a potentiation of the trauma response at the 100 gm-cm and 260 gm-cm contusion levels. No significant changes were noted at the(More)
We treated 12 adult patients who had gram-negative bacillary meningitis with cefotaxime administered intravenously at a dose of 2 g every 4 hours. The etiological organisms included Haemophilus influenzae (3 cases), Serratia marcescens (3 cases), Klebsiella pneumoniae (3 cases), Escherichia coli (2 cases), and Enterobacter (1 case). The infection followed a(More)
