Topical application of human leukocyte interferon in stasis ulcers and deep burns.

Human leukocyte interferon (HLI) incorporated in ointment (4,000 units/g) applied topically for 4 weeks induced the process of "scavenging" granulation and epithelialization of stasis ulcers. This therapy had a better effect than that of the other combined local and general therapy also given in the study. A comparison of the effects of both therapies was made on nine pairs of stasis ulcers.
