[The use of ultrasound at different frequencies in the treatment of patients with the neurological manifestations of osteochondrosis of the lumbar spine].

85 patients with lumbar spine osteochondrosis associated with lumbar ischialgia and radiculopathy were examined and treated using high- or low-frequency ultrasound. Low-frequency ultrasound was found superior to high-frequency one primarily in patients with acute disease and concomitant spondylarthritis.

[Polymorphonuclear rosettes in the peripheral blood of multiple sclerosis patients].

The study is related to the distribution of rossette-forming cells--lymphocytic and polymorphonuclear leukocytic--lymphocytes and polymorphonuclear leukocytes (neutrophils) in the peripheral blood of patients with disseminated sclerosis. An increase of the polymorphonuclear leukocytes and polymorphonuclear leukocytic content was found in the exacerbation period. Similar data were obtained in the process of reproduction of chronic experimental allergic encephalitis in maccaca rhesus.
