Indomethacin protects against neurodegeneration caused by MPTP intoxication in mice.

The anti-inflammatory agents are postulated to be effective in treating neurodegenerative disorders. In this study, we showed that indomethacin (IND) in the dose of 1 mg/kg protected neurons against toxic damage caused by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in mice model of Parkinson's disease. IND also diminished microglial activation and lymphocytic infiltration in the injured areas. These observations suggest that anti-inflammatory properties of IND may play a role in the neuron's protection in this model. However, diminished inflammatory reaction may be secondary to less neuronal damage.

Chronic progressive axonal polyneuropathy simulating Guillain-Barré syndrome.

Six cases of chronic progressive and/or relapsing polyneuropathy are reported. All cases were idiopathic at the beginning of observation. Electrophysiological examination and biopsy of sural nerve in all cases as well as autopsy of spinal roots S1 in case 6 showed loss of fibers and axonal degeneration of myelinated fibers but neither active demyelination nor inflammatory cells were observed. Chronic progressive or relapsing idiopathic axonal polyneuropathy appear to be a distinct entity different from GBS. The term "axonal GBS" seems to be questionable.

Morphological and biochemical changes in peripheral nerves with aging.

The ulnar nerve taken at autopsy from 30 subjects aged 24-98 who died without features of clinical involvement of peripheral nerves was examined morphologically. Density of myelinated fibers (m.f) per 0.1 mm2, frequency distribution of the external diameter of m.f., and teased fiber were estimated. Besides, in 8 nerves some lipids were assessed biochemically. The study showed that the percentage of fibers with morphological changes increases with aging (7-10% in adults and even up to 35% in aged subjects). In older subjects loss of m.f. may be marked. Morphological changes in the nerves of subjects in all groups of age are unspecific (axonal degeneration, and segmental demyelination). Striking feature for the nerve is the preserved ability to repair damage of the fiber independently of the subjects' age. Accidental factors play some role as a cause of morphological changes in the nerve in all groups of age but in the elderly, aging of the neuron seems to be an important factor. Biochemical changes in the nerves with age are not prominent, and much less expressed than morphological changes.

[Selective mechanical dilatation of brain arteries: intracranial angioplasty].

Intracranial vascular stenosis of haemodynamic significance is underappreciated both clinically and diagnostically. It is thought to be the cause of cerebral ischaemia in 8% of patients. Now it is possible to perform dilatation of the intracranial arterial stenosis by modern intraarterial angioplasty. Two cases are presented of successful dilatation of middle cerebral artery trunk stenosis. Diagnostic problems, follow up and pharmacological treatment as well as technique of intravascular treatment is described.
