Characteristics of the antigen-binding properties of lymphocytes in experimental Salmonella infection

The data on the count of antigen-binding lymphocytes in the blood and lymphoid organs of mice in the course of Salmonella infection are presented. The reaction used for their detection is specific. Antigen-binding lymphocytes detected in mice in Salmonella infection belong to T- and B-cell populations and carry surface receptors belonging to IgA and IgM. Study of antigen-binding lymphocytes 1-20 hours after infection may be helpful in the specific diagnosis of Salmonella infections.     

Azaphilones: a class of fungal metabolites with diverse biological activities

This review presents an overview of azaphilones isolated from different species of fungi, detailing their chemical structures and biological activities as covered in the recent literature. Over 170 different azaphilone compounds occur in fungi belonging to 23 genera from 13 families: these azaphilones can be classified into ten different structural groups. Numerous azaphilone structures have been described, particularly from members of the Trichocomaceae and Xylariaceae families. Azaphilones exhibit a wide range of interesting biological activities, such as antimicrobial, antifungal, antiviral, antioxidant, cytotoxic, nematicidal and anti-inflammatory activities. Many of these effects may be explained by the reactions of azaphilones with amino groups, such as those found in amino acids, proteins and nucleic acids, resulting in the formation of vinylogous γ-pyridones.
