title: [Chemical structure and immunostimulating activity of high molecular weight polysaccharides].
abstract: An immunostimulating activity of high molecular polysaccharides, dissimilar in their chemical structure, was studied. Inoculation of mice with bacteria of typhoid fever and Kl. pneumoniae demonstrated that O-polysaccharide from typhoid bacteria--multicomponent, branch-chained, phosphorus-containing polysaccharide--exhibited the highest immunostimulating effect. Mannans and glucans, with linear and branch-chained molecules, involving various types of C-C bonds, had lower stimulating properties, which did not correlate with the level of a molecule branching and the type of C-C bonds. These data were confirmed after evaluation of adjuvant properties of high molecular polysaccharides with sheep erythrocytes and their ability to activate macrophages.
