Delayed hypersensitivity to human encephalitogenic protein as assayed by agarose leucocyte migration in multiple sclerosis patients.

Using a leucocyte migration test (Clausen's direct agarose gel migration method) hypersensitivity to human encephalitogenic protein has been examined in 50 multiple sclerosis patients (group 1), 50 healthy persons (group 2) and 25 patients with other neurological diseases (group 3). In group 1, 30 MS patients (60%) show an abnormal migration index, manifested either as inhibition or stimulation of migration; 29 controls in group 2 (58%), 11 O.N.D. patients in group 3 (44%) show an abnormal migration index. These results mean that lymphocyte hypersensitivity to myelin basic protein appears neither to be constant nor specific to multiple sclerosis. Three migration index curve types at different antigen concentration are obtained: monophasic curves within the normal index zones; monophasic curves staying in the inhibition or stimulation zone and biphasic curves with dose-effect relationship. Whatever the antigen used, this dose-effect relationship implies that the test must be carried out at different concentrations. The meaning of spontaneous sensitisation in healthy controls is discussed.

Long-term treatment of Parkinson's disease with bromocriptine.

BRomocriptine (15-75 mg per day) alone or with L-dopa was studied during five to 29 months on 44 patients with Parkinson's disease. Used as sole therapeutic agent, it was found excellent in 12 patients who had never received regular L-dopa treatment either because it was never attempted or because of intolerance from the outset. Its anti-Parkinsonism activity was comparable with L-dopa. The gain was stable in the long term until this report. The side effects of L-dopa were not seen after bromocriptine. In cases where L-dopa had ceased to be active, bromocriptine produced a further improvement if mental deterioration was not associated. In very advanced forms of Parkinson's disease with associated dementia, bromocriptine did not produce durable results. Bromocriptine did not improve the "on-off" effects but reduced a number of the side effects of L-dopa, in particular cardiac, painful contractions, and dyskinesia without "on-off" effects.

[Computerized cisternography with metrizamide].

Metrizamide, a new water-soluble contrast medium with low toxicity, was used for cranial computed tomography (computerized cisternography) in 26 patients. When injected by lumbar puncture, the pericerebral cisterns (posterior fossa and sella turcica especially), can be visualized with much greater precision than with classical computed tomography. It also allows the normal and pathological circulation of the CSF to be studied. The authors report on 6 cases of tumours of the posterior fossa, 10 cases of pituitary tumours, 2 cases of "empty" sella, 2 cases of CSF rhinorrhoea, 2 cases of normal pressure hydrocephalus, and 2 cases of syringomyelia, studied by this method. The examination was normal in 3 cases. The authors stress the rapidity, reliability, and good tolerance of this new method.
