Enzyme immunoassay (ELISA) was used to study the levels of serum rheumatoid factors (RF) of classes IgM and IgG in patients with spinal injuries and osteochondrosis. The findings show that at the late stages of the disease, the patients with spinal injury show 46% seropositiveness for IgG-RF and 40% for IgM-RF. Patients with fresh central nervous system (CNS) injuries were 12 and 14% seropositive, respectively. Patients with osteochondrosis exhibited 33% seropositiveness for IgG-RF. Determination of serum RF enables the authors to identify systemic body lesions at the late stages of spinal injuries as rheumatic disease. These data support the conclusion that RF determination is a reliable serological indicator of the severity of a patient's traumatic disease.

Enzyme immunoassay was used in the research of the levels of rheumatoid factor (RF) of IgM and IgG in the blood serum of patients with the injury of the spinal cord and osteochondroses. Analysis of the results obtained demonstrated a 46% RF IgG seropositivity and 40% RF IgM seropositivity in the patients with the injury of the spinal cord in the late period of the disease. The patients with freshly injured CNS demonstrated 12 and 14% seropositivity, respectively. Osteochondrosis patients demonstrated a 33% RF IgG seropositivity. The detection of the blood serum RF enabled one to qualify the systemic lesions at the injury of the spine cord in the late period of the disease as a rheumatoid condition. On the basis of the data obtained a conclusion could be made of fact that the detection of RF was a reliable serological test for the assessment of the severity of the condition associated with the injury sustained.

Serum levels of circulating immune complexes (CIC) and those in the liquor were studied in patients with spinal trauma using enzyme immunoassay. CIC and clinical--laboratory findings characterizing the activity of the inflammation were consistent. Assessment of CIC factor in spinal trauma seems clinically valuable as it is involved in inflammation and tissue damage suggesting a prognosis of CIC-related pathology.

[Evaluation of the results of neurorrhaphy using microsurgical and ordinary technics (experimental study)]. / Otsenka rezul'tatov nevrografii s primeneniem mikrokhirurgicheskoi i obychnoi metodik (éksperimental'noe issledovanie).

For comparative assessment of an ordinary epineural suture and neurorrhaphy with the use of neurosurgical techniques operations were conducted on rabbits with a subsequent histological examination. It was established that the granulation tissue containing fine collagen fibers formed more rapidly when microsurgical techniques were used than in the controls. Besides, the rate of growth of the nerve elements in the region of the anastomosis was higher and by the end of the study the newly formed myelin axons acquired a clear linear direction.
