[Delayed hypersensitivity to staphylococcal antigens in patients with staphylodermas].

Basing on analysis of delayed skin reactions to staphylococcal vaccine, on findings of pathohistologic examinations of the skin in foci of delayed type hypersensitivity, on the parameters of the lymphocyte, monocyte, and neutrophil migration into these foci, as well as on the clinical parameters and findings of the spontaneous rosette-formation, lymphocyte blastogenesis, leukocyte migration inhibition tests with the specific antigen, and DNCB skin test, carried out in 312 patients with staphylodermas, the author comes to a conclusion on the protective role of delayed type hypersensitivity to Staphylococcus, reveals some mechanisms of the formation of skin response reactions, and points to some factors responsible for inhibition of these reactions.

[The morphofunctional characteristics of the peripheral lymph nodes in patients with chronic pyoderma].

Pathohistologic examinations of the peripheral lymph nodes in 14 patients with abscessed acne, chronic infiltrative ulcerous and infiltrative fistulous pyoderma coursing for 1 to 11 years have revealed that chronic pyococcal infection induces manifest atrophic and sclerotic changes in the cortical and medullary layers of the regional lymph nodes and of those distant from foci of involvement; these changes are accompanied by essential impairments of the immunologic, lymphopoietic, and other functions.
