title: Effect of morphine, hydromorphone, methadone, mescaline, trypan blue, vitamin A, sodium salicylate, and caffeine on the serum interferon level in response to viral infection.
abstract: The ability of morphine, hydromorphone, methadone, mescaline, trypan blue, vitamin A, sodium salicylate and caffeine to alter the circulating serum level of interferon was investigated in mice. Sodium salicylate, and caffeine increased the serum level of interferon; however, the interferon increase produced by sodium salicylate was dose-dependent, i.e. low doses increased interferon titers, high doses decreased the titers. All other compounds decreased the circulating level of interferon. These results suggest that compounds of varied structure and biological activity, and possessing teratogenic potential, are capable of depressing the circulating level of interferon. Some of these "anti-interferon" compounds, i.e. morphine, hydromorphone, methadone, depressed interferon levels at all doses whereas sodium salicylate decreased the interferon level only at relatively high dose levels.
