Influence of cortisone and cyclophosphamide on xanthine oxidase bacterial activation.

The xanthine oxidase increase in mice liver as response to infection was studied as a possible parameter useful for a better understanding of theimmunosuppression due to cyclophosphamide and cortisone. An impact of cortisone but not of cyclophosphamide on this mechanism was found; this may be useful in order to discriminate between the two different types of immunosuppressive drugs.
