It is an often reported observation in the literature on multistable perception that the reversal rate within a given observation time is subject to a high interindividual variability. Recently, we reported frontal gamma-band enhancement during multistable visual perception. The aim of the present study was to investigate whether changes in the gamma-band(More)
The authors compare recovery and the post-anaesthetic period in 45 patients anaesthetised with a combination of either pentothal, nitrous oxide, fluothane and dolosal (group 1, 24 subjects), or of pentothal, nitrous oxide and phenoperidine (group 2, 21 subjects). The quality of recovery was judged at the end of anaesthesia by determining of occurrence of(More)
Levamisole was given orally to 3 groups of dogs, totaling 56 animals. Drug administration period varied from 1 to 120 days. All animals were killed and the central nervous system was examined histologically. Lesions were found in 44 of 56 dogs. These consisted of disseminated perivascular cuffing with mononuclear cells throughout the brain and meninges. The(More)
A young cat had signs of tetraparesis that progressed to tetraplegia within a few weeks. Clinically, there was lower motor neuron disease with areflexia and muscle atrophy in all limbs. Degeneration of the motor neurons in the spinal cord was seen on histological examination. Ultrastructurally, the degeneration of nerve cells was characterized by abnormal(More)
Two young zebra siblings from consecutive pregnancies suffered from neurological disease, characterized by ventral deviation of the neck and tetraparesis which progressed to tetraplegia within a few weeks. On histological examination widespread neuronal degeneration was observed in the ventral horns of the spinal cord and in the lower brain stem.(More)
We have previously reported the isolation of mammalian cell lines expressing the 3-methyladenine DNA glycosylase I (tag) gene from E. coli. These cells are 2-5 fold more resistant to the toxic effects of methylating agents than normal cells (15). Kinetic measurements of 3-methyladenine removal from the genome in situ show a moderate (3-fold) increase in Tag(More)
The authors suggest the hypothesis that the obesity often associated with sleep apnea syndromes is related to changes in HG secretion. Indeed, as HG secretion is sleep related any disturbances due to apnea during may alter the GH secretion. In order to test their hypothesis the authors studied, during the course of 24-hour polygraphic recordings, the levels(More)
One of 8 highly inbred Dalmatian pups was born with generalized body tremors, which interfered with the pup's ability to suckle, walk, and maintain sternal recumbency. The pup's head, neck, and limbs oscillated rhythmically when it attempted to perform any motor function. The pup was euthanatized at 8 weeks of age, after it became apparent that the disorder(More)
