Cerebrospinal fluid protein changes in multiple sclerosis after dental amalgam removal.

A relationship between multiple sclerosis (MS) and dental silver-mercury fillings has been suggested by some investigators, but never proven. This study documents objective biochemical changes following the removal of these fillings along with other dental materials, utilizing a new health care model of multidisciplinary planning and treatment. The dramatic changes in photolabeling of cerebrospinal fluid (CSF) proteins following these dental interventions suggest CSF photolabeling may serve as an objective biomarker for monitoring MS. The clear-cut character of these changes should also encourage more research to better define this possible association between dental mercury and MS.

Cerebrospinal fluid proteins and cells in normal-pressure hydrocephalus.

A total of 21 patients with normal-pressure hydrocephalus were examined. Cerebrospinal fluid (CSF) was collected before and after operation with a ventriculoperitoneal shunt. A slight plasma-like protein pattern indicating a blood-brain barrier (BBB) dysfunction was seen in 38% of the patients before operation. No characteristic changes could be found in the "CSF-specific" protein fraction. After the shunt operation 65% of the patients had a BBB dysfunction to macromolecules and 70% had two additional acidic protein bands in the CSF-specific fraction. Ventricular CSF protein content was 73% of lumbar CSF content when shunts were patent. Isotope encephalography showed a radionuclide accumulation at the intracranial part of the shunt system, indicating that the BBB damage might be located round the shunt catheter.

Immunoblotting techniques with picogram sensitivity in cerebrospinal fluid protein detection.

Agarose isoelectric focusing followed by blotting with nitrocellulose, nylon or polyvinylidene difluoride membranes, and immunochemical detection of cerebrospinal fluid IgG with various combinations of antisera, was evaluated. Polyvinylidene difluoride proved to be an easy-to-handle and reliable membrane for protein blotting. Among immunochemical visualization reactions, the most sensitive employed biotinylated goat anti-human IgG followed by streptavidin colloidal gold conjugate and silver enhancement in 20% w/v urea, allowing a sensitivity of less then 1 picogram IgG/band.
