[Dynamics of serum immunoglobulin concentrations in the rabbit during experimental food anaphylaxis]

The content of serum IgG, IgM and IgG was studied in rabbits at varying times of oral sensitization of animals before and after administration of the resolving dose of food protein. The content of IgG was found to be reduced on the 19th-21st day of sensitization. Meanwhile the content of IgA increased on the 24th day of oral sensitization. Administration of the resolving dose of protein on the 19th day of sensitization was followed by the reduction of IgG content. A reverse correlation was revealed between the changes in the content of IgG and the degree of food anaphylaxis in rabbits.
