Several biochemical parameters, the most important of which are total IgG, kappa and lambda light chain distribution and thin layer isoelectric focusing, were determined in the cerebrospinal fluid of 36 multiple sclerosis patients. Their ages and the evolution period of their disease are widely spre

β¦ Synopsis
Despite enormous efforts to find a specific laboratory test for multiple sclerosis, agar gel electrophoresis of the CSF proteins has remained the next to the best one. This study presents evidence that thin layer polyacrylamide isoelectric focusing of the CSF gamma globulins is by far superior for this purpose. In effect, about 91% of the 262 multiple sclerosis patients studied had oligoclonal fractions present in the very alkaline region of the pH gradient. Of the same group of patients only 65% did show pathological results when studied by agar gel electrophoresis. Of the 272 CSF samples from patients suffering from other neurological diseases, only about 7% showed the presence of oligoclonal bands in the same region of the pH gradient, when submitted to isoelectric focusing.

In the second paper of this series, a detailed study of the three main serum immunoglobulins for a group of 772 MS patients is compared with a group of 226 neurological controls. The results are studied according to sex and different age groups. Except for a slight elevation of the IGM levels in the
Lymphocyte stimulation tests with human basic protein of myelin were performed on patients with multiple sclerosis, with other neurological diseases and on normal subjects. In both MS and OND group, a hypersensitization to basic protein was seen in about one third of the cases. All normal subjects,
