Alternative approach to the treatment of diabetes mellitus.

The influence of insulin preparations (Actrapid and Ransulin) on the glucose and insulin blood level has been studied in patients with diabetes mellitus. It has been shown that comparable changes in the measured parameters are achieved in most patients with oral doses of Ransulin that are two to three times higher than the doses of Actrapid.

Trends in the synthesis of metal oxide nanoparticles through reverse microemulsions in hydrocarbon media.

In recent years, more and more attention is given to production and use of nanoparticles dispersed in hydrocarbon medium and synthesized in reverse microemulsions. In this article the data and research results on synthesis of inorganic nanoparticles in reverse microemulsions are summarized. The major attention is paid to thermochemical approach for nanoparticle synthesis in reverse microemulsions with precursors of Мо, Al, Ni, Co and Fe oxides being active components of the catalysts for petroleum chemistry and refinery.

[The morphology of microcolonies as a criterion for recognizing bacteria in the differentiation of Streptococcus pyogenes and Streptococcus group B].

The authors studied the diagnostic importance of the morphology of microcolonies of S. pyogenes and group B streptococci in comparison with the currently used tests for the differentiation of these two species: the bacitracin test, the hydrolysis of sodium hippurate and the CAMP test. The standard tests proved to be positive in 94-97% and microcolonies had typical morphology in 86-95.

[Correlation between blood levels of uric acid and calcium in rheumatoid arthritis and deforming polyosteoarthrosis].

The markedness of the inflammatory reaction and severity of a noninflammatory tissue-articular destruction correlated with accumulation of 99Tc-pyrophosphate in articular structures. Uricemia and calcemia decreased as the activity of rheumatoid arthritis rose and they correlated with the severity of destructive changes.

[Microcolony morphology as a criterion in bacterial diagnosis. The differentiation of Pneumococcus from alpha-hemolytic Streptococcus].

The authors have developed a method permitting the microscopic study of the morphology of bacteria and their relative position in microcolonies. Thus, the use of this method has made it possible to distinguish Streptococcus pneumoniae from other bacteria by the morphology of their microcolonies. In the study of 75 streptococcal strains, all strains yielding positive results in two or three tests, similarly to all strains pathogenic for mice, formed microcolonies with granular (pneumococcal) morphology, while all strains yielding negative results have been found to form microcolonies with catenulate ("nonpneumococcal") morphology.
