[The contribution of genes polymorphism of thrombophilia in clinical variability of hemorrhagic vasculitis].

Background: The article is devoted to the study of clinical and laboratory characteristics of the current of hemorrhagic vasculitis in children in the Republic of Buryatia.

Patients And Methods: The study included 27 patients aged 7.6 +/- 4.

[Creation of a controlled model of respiratory mycoplasmosis].

To create the controlled model of respiratory mecoplasmosis, laboratory animals with induced immunodefeciency were infected with M. pneumoniae strain having different degrees of virulence. Immunodeficient state was induced in susceptible animals (hamsters) by the injection of cyclophosphamide.

[Differential activity of genes of Mycoplasma pneumoniae in acute and chronic forms of experimental infection].

The complex of investigations was carried out with a view to study the mechanisms making it possible for mycoplasmas to switch off the expression of definite genes in persistence. The main method used in these investigations was the method of molecular portrayal, or RNA fingerprinting, with the use of arbitrary primers. The comparative analysis of gene expression in M.
