[Role of intraspinal hypertension in the pathogenesis of discogenic lumbar radiculitis and its treatment by dehydration therapy using mannitol].

Dehydration with mannitol was carried out in 58 patients suffering from grave discogenic lumbar radiculitis. A favourable effect was obtained in 43% of the cases. At the onset of the clinical manifestations of the osteochondrosis good and excellent results were obtained in 60% of the cases. As the test stimulation electromyography was used. The role of edema of the disc and spinal radicle tissues in the clinical manifestations of the discogenic lumbar radiculitis is discussed.

[Functional nature of the spinal center of the hand muscles in normal subjects and in certain neurologic diseases (according to the results of stimulation electromyography)].

The parameters of the motor and the central responses of the thenar muscles to stimulation of the median nerve in 28 healthy subjects and 85 neurological patients were examined. It was shown that the infracervical alpha-motoneurons responded only to antidromic stimulation (the F-wave was registered). In cerebral pareses monosynaptic transmission from the 1a afferents becomes possible (the central response is similar to the H-reflex): this points to a disturbance of the segmented inhibition. In processes involving the anterior corticospinal tract the F-wave is depressed down to its complete disappearance, i.e. the motoneurons lose their capacity to respond to antidromic stimulation.
