[Biological characteristics of Staphylococci circulating in hospitals in Nizhniĭ Novgorod].

The study of 513 clinical isolates of staphylococci revealed that 8.4% of them were methicillin-resistant, their proportion in the isolates obtained from hospital patients being significantly higher than in the isolates obtained from patients in outpatient clinics (11.8% compared with 1.

[Comparative in vitro activity of ampicillin, cefoperazone, their combinations with sulbactam and other antibiotics with respect to staphylococci and pneumococci].

Antibiotic susceptibility of 225 Staphylococcus strains and 42 Pneumococcus strains was assayed with the method of serial microdilutions. Methicillin resistant Staphylococcus strains (S. aureus and coagulase negative strains) were characterized by high susceptibility to cephalosporins and ampicillin + sulbactam combination, as well as to ciprofloxacin, rifampicin and vancomycin (70 to 100 per cent of the susceptible strains).

[Comparative in vitro activity ampicillin, cefoperazone, their combinations with sulbactam, as well as that of other antibiotics against aerobic gram-negative microorganisms].

The activity of 12 antibiotics against 849 strains of gram-negative aerobes isolated in special and general hospitals of Moscow and Smolensk in 1992-1993 was assayed with the method of serial microdilutions. By the criteria of the activity (percentage of the susceptible strains by the NSSLS criteria) against the isolates the antibiotics were arranged as follows: ciprofloxacin (89.8 per cent) > imipenem (89.

[Glial volume test for patients with schizophrenia and its changes during therapy].

Glial volume test (GVT) was used to assess cytotoxic antibrain antibodies in 64 schizophrenic patients and 42 patients with organic disorders of the central nervous system. The GVT changes were unspecific and reflected the general course of the disease. Serum cytotoxicity increased with increasing psychopathological signs and reduced to normal or subnormal values with their alleviation.

[Clinico-psychopathologic and electroencephalographic correlations in patients with cranio-cerebral trauma during laser therapy].

A total of 96 patients with severe craniocerebral trauma were treated and divided into 3 groups: 1, with prevailing left brain hemisphere lesions manifested by right-sided pyramidal symptoms (N = 32); 2, prevailing right brain hemispheric lesions and left hemisyndrome (N = 35); 3, lacking in distinct focal interhemispheric differences in trauma localization with prevalent general cerebral signs. Control group consisted of 45 patients conventionally drug-treated without laser. Laser therapy was performed as a course of 12 to 15 sessions according to regimens settled for each group of patients.
