Abstract
Lymphokines such as migration inhibitory factor and type II interferon were released into the circulation of tuberculin-sensitive mice after iv injection of old tuberculin. Daily administration of such sera into the tumor sites of mice given implants of sarcoma MC-36 markedly suppressed tumor growth.
