[Immune status of patients with chronic tonsillitis before and after tonsillectomy]. / Immunnyi status bol'nykh khronicheskim tonzillitom do i posle tonzilléktomii.

Immune status was examined before and after tonsillectomy in 35 patients with various forms of chronic tonsillitis (CT). Measurements were made of main lymphocyte populations, IgA, IgG, IgM levels, functional activity of neutrophils, titers of antibodies to opportunistic microorganisms of the upper airways. It is shown that tonsillectomy produces positive changes in some immunological indices: serum IgG normalized, titers of antibodies to Haemophillus influenzae, Streptococcus pneumoniae and streptolysin-0 lowered, initially low count of B-lymphocytes, natural killers, T-helpers rose, neutrophil chemiluminescence normalized.

[Clinico-immunological effectiveness of likopid in conservative treatment of patients with chronic tonsillitis and chronic sinusitis]. / Kliniko-immunologicheskaia éffektivnost' likopida pri konservativnom lechenii bol'nykh khronicheskim tonszillitom i khronicheskim sinusitom.

30 patients with chronic tonsillitis (CT) and 20 patients with chronic sinusitis (CS) received likopid (4 mg/day for 10 days). CT patients were additionally treated with tonsil lacunar lavage with dioxidine solution. Likopid was found effective in CT patients (good response--31%, partial response--59%). 9% did not respond to likopid. CS patients benefited less (good response--10%, partial response--50%). 40% were non-responders. In CT patients likopid demonstrated also an immunomodulating effect. Positive changes were observed in the counts of B-lymphocytes, T-lymphocytes, T-helpers, natural killers, level of serum IgG, titers of specific antibodies, functional activity of neutrophils. In CS this effect was less pronounced.

[The effect of various protein kinase inhibitors on the response of snail neurons to the intracellular injection of cAMP]. / Vliianie razlichnykh ingibitorov proteinkinazy na éffekt vnutrikletochnoi in''ektsii tsAMF v neirony vinogradnoi ulitki.

Drugs preventing cAMP interaction with regulatory subunit of cAMP-dependent protein kinase, tolbutamide and db-cAMP injected into neurons of Helix lucorum decreased the cell response to cAMP, but H-8-a potent inhibitor of this enzyme catalytic subunit did not produce such effect. It is suggested that the neuron electric response to cAMP injection is not caused by protein phosphorylation.

[An intracellular inhibitory activity of RNase secreted by Bacillus intermedius]. / Vnutrikletochnaia ingibitornaia aktivnost' RNKazy, sekretiruemoi Bacillus intermedius.

Bacillus intermedius cells producing extracellular RNAse were found to contain its inhibitor and an RNAse-inhibitor complex. Bacillus subtilis and Escherichia coli cell lysates did not inhibit the activity of homogeneous extracellular RNAse produced by B. intermedius. The inhibitor was shown to be specific for this RNAse and did not interact with other RNAses. As was demonstrated by biochemical tests and electrophoretic analysis, the inhibitor is released when the protoplasts are disintegrated, i.e. it is located in the cytoplasm. A correlation has been established between the biosynthesis of extracellular RNAse and its intracellular inhibitor.

[Intracellular and extracellular ribonucleases of Bacillus intermedius]. / Izuchenie vnutrikletochnykh i vnekletochnykh ribonukleaz Bacillus intermedius.

Endocellular and exocellular ribonucleases were studied in Bacillus intermedius. Two fractions of ribonucleases (Rf 0.72 and 0.96) were found to be associated with the cellular surface and seven fractions (Rf 0.1, 0.17, 0.33, 0.45, 0.72, 0.82 and 0.96) were detected in the cytoplasm. RNAase with Rf 0,096 had the highest activity and was repressed by inorganic orthophosphate. This RNase accumulated in the cell during the stationary growth phase just as the free enzyme form did in the culture medium. The immunological characteristics of these enzymes were identical as was shown by immunochemical analysis.
