[Effect of remantadine and ribavirin on the production and antiviral action of human interferon types I and II]. 1982

D N Nosik, and R D Aspetov, and A S Novokhatskiĭ

The results of using human interferon of types I (alpha- and beta-interferons) and II (gamma-interferon) in combination with chemotherapeutic drugs, such as remantadin and ribavirin for the study in human cell cultures are presented. Moderate doses of the drugs (25 microgram/ml) did not eliminate the interferon production. In higher doses (50 microgram/ml) they lowered the interferon production levels 2--3 times. In the presence of ribavirin the level of the interferon production lowering was higher. On the whole the effect of the drugs on production of interferons of types I and II was of a similar character despite the different means of interferon induction. The combined use of interferons of types I and II with the chemotherapeutic drugs in human embryo cultures infected with Semiliki forest virus (SFV) revealed an additive character of the antiviral effect in all combinations tested. The level of the antiviral activity of alpha-, beta- and gamma-interferons against the SFV was practically the same.

UI	MeSH Term	Description	Entries
D007369	Interferon Inducers	Agents that promote the production and release of interferons. They include mitogens, lipopolysaccharides, and the synthetic polymers Poly A-U and Poly I-C. Viruses, bacteria, and protozoa have been also known to induce interferons.	Inducers, Interferon
D007372	Interferons	Proteins secreted by vertebrate cells in response to a wide variety of inducers. They confer resistance against many different viruses, inhibit proliferation of normal and malignant cells, impede multiplication of intracellular parasites, enhance macrophage and granulocyte phagocytosis, augment natural killer cell activity, and show several other immunomodulatory functions.	Interferon
D002478	Cells, Cultured	Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.	Cultured Cells,Cell, Cultured,Cultured Cell
D002642	Chick Embryo	The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching.	Embryo, Chick,Chick Embryos,Embryos, Chick
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000218	Adamantane	A tricyclo bridged hydrocarbon.	Diamantane
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D000998	Antiviral Agents	Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.

D012254	Ribavirin	A nucleoside antimetabolite antiviral agent that blocks nucleic acid synthesis and is used against both RNA and DNA viruses.	Ribovirin,Tribavirin,ICN-1229,Rebetol,Ribamide,Ribamidil,Ribamidyl,Ribasphere,Vilona,Viramide,Virazide,Virazole,ICN 1229,ICN1229
