A therapeutic strategy was designed to eliminate the humoral immune response to acetylcholine receptor (AChR) in ongoing experimental autoimmune myasthenia gravis (EAMG). Rats with EAMG were treated with a protocol consisting of three components: (1) A single high dose of cyclophosphamide (200 mg/kg) was used to produce a rapid and sustained fall in the(More)
We demonstrate that treatment with the cytokine human interferon-beta (IFN-beta) resulted in a beneficial outcome in a rabbit model of thromboembolic cerebral ischemia. Rabbits administered subcutaneously with IFN-beta prior to (pre-treatment) or after (post-treatment) the introduction of an autologous blood clot into the middle cerebral artery have(More)
Fasting serum glucose, glycosylated hemoglobin, and fructosamine concentrations were determined in 304 consecutive subjects admitted with acute stroke, within 48 hours of ictus. Based on the medical history and these results, subjects were divided into known diabetics, newly diagnosed diabetics, subjects with stress hyperglycemia, and nondiabetics. The type(More)
Tuberculostearic acid, a structural component of Mycobacterium tuberculosis, was identified by gas chromatography/mass spectrometry with selected ion monitoring in cerebrospinal fluid (CSF) from 13 patients with proven and 8 out of 9 patients with suspected tuberculous meningitis; the negative result was in a patient whose symptoms and CSF abnormalities may(More)
The Shatin Stroke Registry is a prospective study of all patients admitted with acute stroke to a general hospital in Hong Kong where the population is predominantly Chinese. Each patient was examined by a neurologist and 95.5% of the patients had a brain CT. Of 777 patients included in the study, 44.0% had a cortical/subcortical infarct, 18.5% a(More)
Five patients on chemotherapy for tuberculous meningitis developed sudden and unexpected cerebrospinal fluid pleocytosis consisting predominantly of polymorphonuclear leucocytes. The cellular changes, which developed 4-108 days after starting treatment, were not accompanied by an alteration in the clinical state and disappeared within a week whether or not(More)
[125I]Bolton Hunter conjugate of substance P ([125I]BHSP) can bind to human astrocytoma membranes in a monophasic and saturable manner with a Kd of 0.57 +/- 0.17 nM and a Bmax of 67.8 +/- 5.5 fmol/mg protein. The rank order of potency of tachykinins and related analogues as inhibitors of [125I]BHSP binding to astrocytoma membranes and intact cells(More)
Thymectomy was carried out for treatment of myasthenia gravis in 27 unselected Chinese patients and thymoma was found in 13 of them. This 48% incidence of thymomas is two to three times greater than in Japanese and European patients, respectively. The reason for the higher incidence of thymomas observed in Chinese patients may be related to the presence of(More)
Binding of 125I-insulin to primary cultures of differentiated mouse astrocytes was time-dependent, reaching equilibrium after 2 h at 22 degrees C, with equilibrium binding corresponding to 20.79 fmol/mg of protein, representing approximately 5,000 occupied binding sites/cell. The half-life of 125I-insulin dissociation at 22 degrees C was 2 min, with an(More)
