The present invention concerns a compound consisting of RNA, in particular RNA extracted from yeast, a pharmaceutical composition comprising such RNA and a method for the treatment of inflammatory and inflammatory-related disorders comprising administering to a patient in need of such treatment a pharmaceutical composition comprising an amount effective to ameliorate the symptoms of inflammation or inflammatory-related disorder of ribonucleic acid and a pharmaceutically acceptable vehicle, carrier, or diluent. The exogenous yeast RNA used in the present invention has a pronounced membrane-stabilizing action in a wide range of concentrations. At the same time, yeast RNA normalizes metabolism of arachidonic acid and levels of its key metabolites, thromboxane and leukotriene. Its anti-inflammatory action is accompanied by normalization of the activity of NO-synthetase and anti-oxidant activity.

The invention claimed is: 1. A method of protecting erythrocytes, which comprises administering to a mammal in need of such treatment an effective amount of ribonucleic acid extracted from yeast and an acceptable vehicle, carrier, or diluent, wherein said ribonucleic acid extract has been purified
The invention claimed is: 1. A method of protecting erythrocytes, which comprises administering to a mammal in need of such treatment an effective amount of ribonucleic acid extracted from yeast and an acceptable vehicle, carrier, or diluent, wherein said ribonucleic acid extract has been purified so that it comprises more than 14.5% by weight nitrogen and more than 8.5% by weight phosphorus, and wherein the ribonucleic acid extract is administered to a relatively healthy individual or athlete showing symptoms of anemia, a cancer patient, or an HIV-infected patient. 2. A method in accordance with claim 1, wherein said ribonucleic acid is administered in an amount within a range of from 0.1 mg to 1 g per kg weight of a mammal. 3. A method in accordance with claim 1, characterized in that said ribonucleic acid is administered in an amount within a range of from 0.1 to 1 g. 4. A method in accordance with claim 1, wherein said ribonucleic acid is obtained from a Saccharomyces cerevisiae. 5. A method in accordance with claim 1, wherein said ribonucleic acid is obtained from a Candida utilis. 6. A method in accordance with claim 1, wherein said ribonucleic acid is administered by an intradermal, hypodermal, oral, intra-abdominal, intramuscular, or intravenous route. 7. A method in accordance with claim 1, wherein said ribonucleic acid is administered in the form of capsules. 8. A method in accordance with claim 1, wherein said ribonucleic acid is administered in the form of suppositories. 9. A method in accordance with claim 1, wherein the ribonucleic acid extract is administered to a cancer patient or an HIV-infected patient showing symptoms of blood cytopenia, and the blood cytopenia is selected from the group consisting of anemia, thrombocytopenia, neutropenia, and combinations thereof. 10. A method in accordance with claim 9, wherein the blood cytopenia is anemia. 11. A method in accordance with claim 9, wherein the blood cytopenia is thrombocytopenia. 12. A method in accordance with claim 9, wherein the blood cytopenia is neutropenia.
