In our laboratory, the classical agarose gel electrophoretic technic allowed the detection of CSF oligoclonal bands in only 40% of the MS patients. This relatively low percentage in comparison with those obtained by other investigators led us to develop a much more resolving electrophoretic technic: an agarose gel isoelectric focusing (IEF) with silver staining. By this method, we detected oligoclonal immunoglobulins in 43 (43%) of 100 MS-CSF exhibiting only polyclonal patterns on classical electrophoresis. Oligoclonal banding appeared particularly in patients with inflammatory type profile (36/60) according to Schuller's classification, but also in those with normal (5/26) or inflammatory transudative (2/8) type profiles. MS-CSF with oligoclonal immunoglobulins on IEF had a higher IgG/Albumin ratio (p = 0.01) than those with polyclonal immunoglobulins, while the mean IgG levels were not significantly different (p = 0.07). These results support the diagnostic usefulness of the IgG/Albumin ratio. Agarose IEF appears to be a useful technic in the detection of oligoclonal immunoglobulins and may be applied at least to CSF of patients with clinical signs of multiple sclerosis.</p>","PeriodicalId":75535,"journal":{"name":"Archives de l'Institut Pasteur d'Algerie.

A direct correlation might exist between the proportion of cells bearing intracytoplasmic IgA determinants and the serum amounts of alpha chain disease protein. Relevant evidence raised from study of proliferating lymphoid cells using the unlabeled peroxidase anti-peroxidase method of immunocytochemistry. The percentage of cells expressing intracytoplasmic alpha chains was found to be greater readily secreting case than in hyposecreting case of alpha chain disease. Furthermore, the cells from secreting situation exhibited much more pronounced specific staining, indicative of probably more active synthesis state. Taken together with histological data, these results suggested a possible late evolutionary pathway without detectable intracytoplasmic and serum alpha chain disease protein.
