[Persistent carotid-basilar anastomosis: arteria proatlantica in ipsilateral aplasia of the vertebral artery and contralateral hypoplasia].

We report on a rare case of aplasia of the left vertebral artery, while the basilar artery is supplied by the proatlantal artery, a persistent carotid-basilar anastomosis. The right vertebral artery appears to be hypoplastic.

Interaction of dichloromethane and ethanol in rats: toxicokinetics and nerve conduction velocity.

The influence of a single combined administration of ethanol (174 mmol/kg per os) plus dichloromethane (1.6, 6.2, or 15.

[Neuropathies following carbon monoxide poisoning].

According to the experiments carried out in animals, impairments of the peripheral nerves can, with a certain regularity, also be expected in patients in the presence of the respective high degree of carbon monoxide intoxications without clinical paralytic symptoms being detectable in every case. The changes in the motor nerve conduction velocity in our patients and in animal experiments are still found over a prolonged period of time after the acute intoxication.

[Animal experiments and clinical observations on poisoning with metallic mercury].

Albino rats of an own culture strain exposed to mercury were investigated electroneurographically. A disturbance of the motor nerve conduction of the ischiadic and the tibial nerve could not be established after one year. Workers exposed to mercury of two chemical plants of the district of Halle were examined neurologically and electrophysiologically.
