Plasmapheresis in the treatment of myasthenia gravis.

Between 1978 and 1980, 10 patients with myasthenia gravis underwent treatment by plasmapheresis. Of these, 7 responded to plasma exchange. Pre- and post-exchange anti-acetylcholine receptor antibody concentrations were found to be a useful parameter for intraindividual comparisons, but failed to correlate with the stage of the disease.

[Determination of average fiber density (single fiber lead), quantitative electromyography and serum CK in the detection of Duchenne carriers].

The fibre density of the extensor digitorum communis muscle was examined with a monopolar single fiber electrode in 2 definite, one probable and 15 possible Duchenne-carriers. In addition serum-CK was evaluated three times in intervals of a least one week. The fibre density was increased in one definite, one probable and 4 possible carriers (greater than 1.

[Placebo-controlled EEG-double blind study with the further purified TBE-vaccine (author's transl)].

In a placebo-controlled double blind study at random with 72 healthy persons the effect of an active TBE-vaccination (purified TBE vaccine) on EEG was investigated. 49 out of 72 examined persons could be examined twice, before and 3 to 5 days after vaccination respectively. The EEG was registered according to the international 10-20 electrode system in bipolar, unipolar and source derivations, using a 16 channel Elema-Schoenander electroencephalograph.
