By means of a new technique (Particle Counting Immunoassay), we have determined the level of ferritin in 470 samples of cerebrospinal fluid of patients with various neurological disorders. The median value obtained in a control group was 2.3 ng/ml with an upper limit at 5.5 ng/ml. the concentrations in the serum and cerebrospinal fluid were independent, but(More)
We have previously reported on the induction, in mice, of a systemic (splenic) immune response with IgA as the dominant antibody, as a result of a short (4 day) intragastric immunization course with foreign erythrocytes. This response was followed by a prolonged period of hyporesponsiveness to similarly administered antigen. Here it is shown that this(More)
S-100 protein was determined by Particle Counting ImmunoAssay in the CSF of patients with various neurological disorders. With a limit of sensitivity of 2.5 micrograms/l this brain-specific protein was detected only in samples from patients with acute damage of the central nervous system, particularly in compression of the spinal cord by tumour, ischaemic(More)
The level of IgM was determined by Particle Counting Immunoassay in the cerebrospinal fluid. In non-neurological patients (N = 20) the mean was 97.5 micrograms/l with the upper reference limit at 380 micrograms/l. The mean IgM index was 0.021 with the upper reference limit at 0.071. Of 21 patients with stroke, 5 had an IgM index exceeding the reference(More)
We assayed immune complexes (IC) by Particle Counting ImmunoAssay in the serum and cerebrospinal fluid (CSF) of patients with various neurological disorders. In pyogenic meningitis, the levels of IC sharply increased 4-8 days after onset with a fall before the 10th day of the disease. In herpetic encephalitis the IC and antibody levels started to increase(More)
