AEROBIC MICROFLORA IN THE PATHOGENESIS OF MAXILLARY SINUSITIS AFTER THE TREATMENT OF CARIES COMPLICATIONS.

Most sinusitis is the result of a periapical infection caused by caries or periodontal disease. The role of bacteria in the initiation of inflammation of the pulp and periapical zones has been well demonstrated. It is well known that colonization of microorganisms in the oral cavity can contribute to the development of pathology of the pulp and periapical organs.

Intraperitoneal Administration of Muramyl Dipeptide β-Heptylglycoside to Pregnant and Non-Pregnant Female Mice Modulates Production of Th1/Th2/Th17/Tr1 Cytokines by Splenocytes Ex Vivo.

Muramyl dipeptide β-heptylglycoside (C7MDP) was administered to non-pregnant CBA female mice and pregnant mice after non-abortion-prone mating (CBA×BALB/c) and mating associated with a high rate of spontaneous abortion (CBA×DBA/2). In non-pregnant females, C7MDP increased the production of IL-2, IL-4, IL-5, IL-6, IL-17, IFNγ, TNFα, and GM-CSF at constant production of IL-1α and IL-10. C7MDP increased the production of IL-10 and IL-17 and suppressed the production of IFNγ on day 8 of gestation in non-abortion-prone mouse couples and stimulated the synthesis of IL-4 and IFNγ, reduced IL-5 production, and slightly increased IL-1α secretion after abortion-prone mating.
