The chemiluminescence activity (CL-A; synonym = burst activity, BA) and the percentage of OKT3-, OKT4- and OKT8-positive peripheral blood cells were serially examined in four control persons and in eight patients with multiple sclerosis. When the OKT values obtained in phases of increased CL-A (clinical remission) were compared with those of the control(More)
The spontaneous chemiluminescence activity (CL-A) of peripheral mononuclear cells (MNC) was examined in Lewis rats with acute experimental allergic encephalomyelitis (EAE), compared to rats immunized with complete adjuvant (n = 11) and healthy animals (n = 16). In rats with EAE, CL-A increased sharply 8-9 days after immunization (3420 +/- 3124 counts/10 s,(More)
In 30 Lewis rats the time course of spontaneous monocyte and granulocyte chemiluminescence activity (CLA) during myelin-induced experimental allergic neuritis (EAN) was studied. CLA of blood and peritoneal cells, and clinical, histopathological and electrophysiological findings were compared with data from 14 animals immunized with complete Freund's(More)
We found that the course of the chemiluminescence activity (CL-A) of peripheral blood monocytes of Lewis rats with acute experimental autoimmune encephalomyelitis (EAE) correlates well with the clinical course of this autoimmune disease and that only a reduction in T helper cells caused a reduction in CL-A. However, in multiple sclerosis (MS) patients the(More)
The plasma from eight patients with multiple sclerosis (MS) whose disease was in remission, was investigated by a chemiluminescence technique for its ability to stimulate the oxidative metabolism of peripheral blood monocytes (PBM). The active fraction identified had a molecular weight between 13,700 and 43,000 Da. Its activity was reduced by incubation at(More)
The course of the spontaneous burst activity (BA) of peripheral blood monocytes was examined in patients with acute polyradiculoneuritis (PN), lymphocytic meningoencephalitis (LE), and multiple sclerosis (MS) and the BA was compared with the clinical course. In 4 patients with postinfectious acute PN the BA was significantly increased up to values around 60(More)
In patients with multiple sclerosis (MS) the spontaneous burst activity (BA) of peripheral blood mononuclear cells was related to the clinical course of the disease. In five patients clinical improvement was found while the BA was significantly increased (more than 300% of the controls). During the appearance of new or deteriorating signs and in the period(More)
The chemiluminescence-activity (CL-A) of peripheral blood monocytes (MO) was measured in eight patients with lymphocytic meningitis or meningoencephalitis and compared to CSF parameters and the clinical course. The initial maximum CL-A was around four times above the control and decreased to normal values within approximately 20 days. Poor correlations were(More)
A 20-year-old woman developed transient right-sided hemichoreatic movements after household exposure to varicella-zoster. Some days before the appearance of involuntary movements a vesicular rash had occurred. About 6 months later an elevated IgG serum titer against varicella virus was found and two-dimensional echocardiography showed signs of an(More)
I has been reported that myelin basic protein (BP) reacts extremely sensitively to peroxide, which is formed when monocytes/macrophages are stimulated to produce a "respiratory burst" (RB). We measured the RB activity by means of chemiluminescence in peripheral blood monocytes/macrophages (MO) of 17 MS patients, 5 patients with a viral infection of the CNS,(More)
