Effects of intranasal administration of the peptide antagonist of type I vaniloid receptor (TRPV1) in the rodent central nervous system.

Intranasal administration of the polypeptide APHC3, an antagonist of the TRPV1 receptor, had acute anxiolytic and antidepressant effects, as well as an ability to modify the microglial response to proinflammatory stress and cytokine profile of the hippocampus. However, the acute antidepressant effect of the polypeptide was not related to the attenuation of neuroiflammation and probably had a different mechanism. The use of intranasal administration of the APHC3 peptide as a therapeutic approach aimed at decreasing depression symptoms needs additional studies in order to find the mechanism of action of this polypeptide in the central nervous system (CNS).

Pumala virus recombinant nucleocapsid protein was used for the early diagnosis of haemorrhagic fever with renal syndrome. Specific IgM in the sera of patients could be determined by the IEA technique as early as on days 2-3 from the onset of the disease. The diagnostic effectiveness of the test-system was 95% and its specificity was 98%.

[Effect of rifampicin, endotoxin, and their combination on the phagocyte activity, microsomal oxidation, and free radical processes in the liver]. / Vliianie rifampitsina, éndotoxina i ikh kombinatsii na aktivnost' fagotsitov, mikrosomal'noe okislenie i svobodno-radikal'nye protsessy v pecheni.

Experiments were conducted on mices to study the effect of strain MRe-600 Escherichia coli endotoxin, rifampicin, and their combination at the level of cytochrome p-450, b5, aminopyrine N-demethylase and aniline-r-hydroxylase activity in the liver, absorptive activity and oxygen dependent metabolism of macrophages, and free-radical processes in the liver. It was found that rifampicin removes the endotoxin-induced depression of microsomal oxidation in the liver, but potentiates the stimulating effect of the endotoxin on macrophageal absorptive activity and the "respiratory outburst" in these cells. The oxidative equilibrium in the liver in this case does not change.

[Immunotropic activity of human alpha1-glucoprotein]. / Immunotropnaia aktivnost' alpha1-kislogo glikoproteina cheloveka.

Experiments were conducted to study the effect of alpha-acid glycoprotein on a fatal infection caused by Pseudomonas pyocyanea, growth of melanoma B-16, and transplantation of a skin graft from C57BL/6 mice to CBA mice. Injection of the agent significantly increased the anti-infection resistance in mice, suppressed growth of melanoma-16, and prolonged the survival of the skin grafts, which was evidence of marked glycoprotein immunomodulating activity.

[The effect of stimulants of immunity on anti-infective resistance and on the activity of the liver monooxygenase system]. / Vliianie nekotorykh stimuliatorov immuniteta na antiinfektsionnuiu rezistentnost' i aktivnost' monooksigenaznoi sistemy pecheni.

The effect of some immunostimulants (bacterial lipopolysaccharide prodigiosan, active thymic peptide T-activin, synthetic compound levamisole) on the anti-infection resistance and metabolic function of the liver (hexobarbital sleeping-time) was studied on noninbred male mice. It was found that when administered in doses and under schedules that protected mice against lethal infection (Pseudomonas pyocyanea, i.p.) prodigiosan and levamisole inhibited metabolism of hexobarbital. T-activin was inactive in both tests. The possible mechanism of correlation is discussed.

[Immunomodulating therapy of adjuvant disease in rats using cyclophosphamide in combination with prodigiozan--its effect on anti-infectious resistance]. / Immunomoduliruiushchaia terapiia ad''iuvantnoi bolezni krys tsiklofosfamidom v sochetanii s prodigiozanom--vliianie na protivoinfektsionnuiu rezistentnost'.

The effect of immunomodulating therapy of adjuvant disease in rats with cyclophosphamide, prodigiozan and their combinations on infection resistance, weight of the lymphoid organs and leukocyte counts in peripheral blood, as well as the effect of prodigiozan on acute toxicity of cyclophosphamide in intact mice and mice exposed to the Freund's complete adjuvant (FCA) was studied. Prodigiozan did not increase acute toxicity of cyclophosphamide in the intact mice. It lowered the cyclophosphamide toxicity at the background of the FCA and decreased the levels of leukopenia induced by the immunosuppressor in the rats with adjuvant arthritis. It was shown on the models of local infectious inflammation caused by Proteus and lethal sepsis due to P. aeruginosa that the combined use of prodigiozan and cyclophosphamide resulted in correction of the infection resistance impairment induced by both the arthritis development and the immunosuppressor administration.

[Immunomodulating therapy of adjuvant disease in rats]. / Nekotorye aspekty immunomoduliruiushchei terapii ad''iuvantnoi bolezni krys.

During a comparative analysis of efficacy of prodigiosan and its combinations with cyclophosphamide (5 mg/kg), asathioprine (4 and 20 mg/kg) and delagil (25 mg/kg) it was shown that the most pronounced suppression of the adjuvant disease was observed in the group of animals given cyclophosphamide with prodigiosan. The suppression of arthritis with cyclophosphamide, prodigiosan and their combination was followed by a decrease of autosensibility parameters--hypersensitivity to collagen and the amount of immune rosette-forming cells in the regional lymph nodes.
