[Antibiotic activity of cortalcerone and its 7-diphenylhydrazone derivative].

The present paper investigates the antibiotic properties of the novel antifungal antibiotic agent cortalceron and its semisynthetic derivative cortalceron 7-diphenylhydrazone. The MIC values were assayed by the agar diffusion method. Cortalceron was found to weakly inhibit the growth of E.

Participation of complement in nasal polyposis.

No changes in immunoglobulin (IgG, IgM and IgA) and complement components C3 and C4 levels could be observed in patients suffering from both recurrent and acute nasal polyposis. However, in both groups of patients a significant decrease of the alternative pathway of complement activation (up to 80%) was found. In addition, patients suffering from the acute disease showed even decreased classical complement pathway (up to 20%).
