Pure rotational R(0) and R(1) lines of CO in Ar baths: experimental broadening, shifting and mixing parameters in a wide pressure range versus ab initio calculations.

The results of a rigorous study of the two first pure rotational transitions of CO perturbed by Ar are presented. The experimental part is based on the use of three different spectrometers covering together the pressure range from 0.02 up to 1500 torr. The measurement results of collisional line shape parameters are supported by fully ab initio calculations, which are in remarkable agreement with retrieved data. A sub-percent uncertainty of line intensity measurements is achieved and the first firm evidence that the resonance spectrum of CO is observed on the continual pedestal is given. We analyze the results of our ab initio calculations on the basis of early analytical theories and demonstrate a good general applicability of the latter to the CO-Ar collisional system.

[Synergistic action of recombinant preparations of gamma-interferon and tumor necrosis factor on the course of experimental staphylococcal infection]. / Sinergidnoe deistvie rekombinantnykh preparatov gamma-interferona i faktora nekorza opukholi na techenie éksperimental'noi stafilokokkovoi infektsii.

The action of recombinant gamma-interferon (rINF-gamma) and tumor necrosis factor (rTNF-alpha) as well as that of their combinations was studied in a model of staphylococcal infection. It was observed that the use of rINF-gamma alone was not sufficient for the activation of the effector antibacterial function of macrophages with respect to staphylococci. At the same time it was shown that rTNF-alpha and rINF-gamma had a synergistic action on the process of the infection in mice evident from an increase in the pathogen elimination in the host. The use of the combination in the optimal doses increased the bactericidal activity of macrophages in the infected animals.

[The efficacy of leukinferon in suppurative-septic diseases]. / Effektivnost' leikinferona pri gnoino-septicheskikh zabolevaniiakh.

In the complex of treatment of purulent-septic diseases leukinferon at a dose of 300 IU/kg was used according to the following scheme: 3 injections with the 48 h interval between injections. The effect of leukinferon mainly on the function of neutrophil granulocytes and subpopulation of T-lymphocytes was established. Together with clinico-laboratory data indicative of the effectiveness of treatment, normalization of interferon status and decrease in the level of a circulating factor of tumour necrosis in seriously ill patients was observed.
