Accuracy of continuous jugular bulb oximetry in the intensive care unit.

Journal Article Neurosurgery · March 1998 OBJECTIVE: To address the accuracy of a bedside jugular bulb oxygen saturation (SjO2) catheter monitor (Baxter-Edwards, Santa Ana, CA) versus in vitro co-oximetry measurements in the intensive care unit (ICU). METHODS: By prospective protocol, we compared ... Full text Link to item Cite

Understanding the physiology of the blood-brain barrier: In vitro models

Journal Article News in Physiological Sciences · January 1, 1998 Endothelial cells exposed to inductive central nervous system factors differentiate into a blood-brain barrier phenotype. The blood-brain barrier frequently obstructs the passage of chemotherapeutics into the brain. Tissue culture systems have been develop ... Full text Cite

Cerebral autoregulation following minor head injury.

Journal Article J Neurosurg · March 1997 The purpose of this study was to determine whether patients with minor head injury experience impairments in cerebral autoregulation. Twenty-nine patients with minor head injuries defined by Glasgow Coma Scale (GCS) scores of 13 to 15 underwent testing of ... Full text Link to item Cite

Neuroprotection by N-methyl-D-aspartate antagonists in focal cerebral ischemia is dependent on continued maintenance dosing.

Journal Article Neuroscience · January 1995 While N-methyl-D-aspartate antagonists have been shown to attenuate neuronal damage in focal cerebral ischemia, few studies have examined whether continuous or multiple dose treatment is necessary for maximum efficacy. We studied the effect of a loading do ... Full text Link to item Cite

Protection against focal cerebral ischemia following exposure to a pulsed electromagnetic field.

Journal Article Bioelectromagnetics · 1994 There is evidence that electromagnetic stimulation may accelerate the healing of tissue damage following ischemia. We undertook this study to investigate the effects of low frequency pulsed electromagnetic field (PEMF) exposure on cerebral injury in a rabb ... Full text Link to item Cite

Dextromethorphan alters cerebral blood flow and protects against cerebral injury following focal ischemia.

Journal Article Neurosci Lett · December 9, 1991 The effects of the N-methyl-D-aspartate (NMDA) antagonist dextromethorphan (DM) on regional cerebral blood flow (rCBF) and cerebral injury were studied in a rabbit model of transient focal ischemia. Anesthetized rabbits underwent 2 h occlusion of the left ... Full text Link to item Cite
