[Study of the safety, reactogenicity, and allergenicity of swine leukocyte interferon in experiments on animals and observations of volunteers].
The results of comparative experiments in guinea pigs sensitized with human and porcine leukocyte interferon are presented. The animals were inoculated either intracardially or intradermally with the appropriate interferon 18-24 days after a single intramuscular or a single subcutaneous interferon injection, the latter with Freund adjuvant. The results of anaphylaxy reaction and dermal reaction permit a conclusion of lower allergenicity of porcine interferon than of human one. Daily intranasal inoculation of both porcine and human interferon for 5 days did not produce sensitization of guinea pigs, and three daily intranasal inoculations for 5 days of porcine interferon to 22 human volunteers produced no untoward systemic or local reactions nor allergic reaction to intradermal inoculation of these volunteers with porcine interferon 24 hours after termination of intranasal administration. These results justify limited clinical trials of therapeutic and prophylactic effectiveness of porcine interferon in viral ARD, using the intranasal route of interferon administration.
