[Photochromotherapy of experimental compression-ischemic neuropathy].

Effects of monochrome light of the green and red spectra (mean wave length 540 and 670 nm, respectively) were studied on experimental rat model of compression-ischemic neuropathy (40 animals). The nerve under compression was exposed to green and red light using light-diode physiotherapeutic unit "Spectr-LC" with different intensity. Electromyographic parameters of the compressed nerve improved significantly after exposure to monochrome green light with intensity 500 mJ/cm2.

[Evaluation of the capacities of neurophysiological intraoperative monitoring in reconstructive surgery on the vertebral column].

Aim: To evaluate the capacities of neurosurgical intraoperative monitoring of somatosensory evoked potentials (SSEP) in reconstructive operations on the vertebral column.

Materials And Methods: The Center of Spinal Surgery examined 30 patients treated in February to July 2001. According to the diagnosis, the distribution was as follows: degenerative diseases of the vertebral column (80%), its tumors (10%), injury (7%), and inflammatory diseases (3%).

[Development of occupational vertebral radiculopathies and tunnel syndromes].

The study proved occupational and everyday strain of muscles and ligaments to be risk factor for ischemic and compression neuropathy. The pathologic changes appeared to involve not only compression points, but also the sites distant from the primary area and ultimately the whole axon. Therefore, spinal roots and nerves could be affected by complicated and multiple ischemic and compression radiculopathies demonstrating typical clinical signs.
