The antiviral activities of normal rat peritoneal macrophages versus Herpes Simplex Virus type 1 were inhibited by sera from tumor-bearing rats and 3M KCl extracts of tumor mass. The inhibitory activity was demonstrated on the extrinsic as well as on the intrinsic macrophage functions. Sera from Corynebacterium parvum and Listeria monocytogenes treated tumor bearing rats did not inhibit these macrophages functions. Furthermore the 3 M KCl extracts from the tumor mass of the above treated TBR show a decrease in the capability to impair these macrophage functions. On the other hand, the treatment with the oral polyvalent adjuvant "Buccalin" was not able to restore the compromised antiviral activity in tumor bearing rats.

Abstract
The antiviral activities of normal rat peritoneal macrophages versus Herpes Simplex Virus type 1 were inhibited by sera from tumor-bearing rats and 3M KCl extracts of tumor mass. The inhibitory activity was demonstrated on the extrinsic as well as on the intrinsic macrophage functions. Sera from Corynebacterium parvum and Listeria monocytogenes treated tumor bearing rats did not inhibit these macrophages functions. Furthermore the 3 M KCl extracts from the tumor mass of the above treated TBR show a decrease in the capability to impair these macrophage functions. On the other hand, the treatment with the oral polyvalent adjuvant "Buccalin" was not able to restore the compromised antiviral activity in tumor bearing rats.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
