Prostaglandins formed by the cyclooxygenase (COX) enzymes are important mediators of inflammation in arthritis. The contribution of the inducible COX-2 enzyme to inflammation in rat adjuvant arthritis was evaluated by characterization of COX-2 expression in normal and arthritic paws and by pharmacological inhibition of COX-2 activity. The injection of(More)
The role of prostaglandin E2 (PGE2) in the development of inflammatory symptoms and cytokine production was evaluated in vivo using a neutralizing anti-PGE2 monoclonal antibody 2B5. In carrageenan-induced paw inflammation, pretreatment of rats with 2B5 substantially prevented the development of tissue edema and hyperalgesia in affected paws. The antibody(More)
A retrospective chart review of 62 children aged 2 to 18.5 years admitted over a 4-year period to a brain injury rehabilitation unit was performed. Glasgow Coma Scales were not always recorded at the referring institutions, but all but three of the children in the series experienced a period of unresponsiveness to the environment for a period of at least(More)
Membrane potential (Vm) is tightly controlled in T cells through the regulated flux of ions across the plasma membrane. To investigate the functional role of voltage-dependent (Kv) and calcium-activated (KCa) potassium channels in T cell activation, we compared the effects of two K+ channel blockers, namely kaliotoxin (KTX) and charybdotoxin (CHTX), on Vm,(More)
BACKGROUND The hypothesis that cyclooxygenase-2 (COX-2) is involved in the myocardial inflammatory response during cardiac allograft rejection was investigated using a rat heterotopic abdominal cardiac transplantation model. METHODS AND RESULTS COX-2 mRNA and protein in the myocardium of rejecting cardiac allografts were significantly elevated 3 to 5 days(More)
Neuromuscular respiratory failure is the cause of death in the majority of patients with ALS. Respiratory muscle dysfunction impacts on quality of life and survival. Attentive management of respiratory muscle weakness is an important aspect of the management of the ALS patient. The respiratory muscles may be thought of as four functional groups: the(More)
Three cases of intracranial meningioma unmasked by elective general anesthesia are reported. In each case, the meningioma was either asymptomatic or so subtly symptomatic that no suspicion of intracranial tumor had been entertained preoperatively. Each patient presented with failure to wake up after routine general anesthesia for a nonneurosurgical(More)
Fifteen cases of delayed traumatic intracerebral hematoma (DTICH) operatively treated are reported. Patients who are awake or only drowsy on admission (Coma Grades 1 and 2, Grady scale) often undergo dramatic sudden neurological deterioration 48 to 72 hours after admission. Emergency computed tomographic scanning and prompt craniotomy for hematoma(More)
