This invention relates to drugs that lead to express proteins involved in redox regulation that antagonize oxidative stresses, which elicit inflammation, alleviate inflammation and thus protect living body. This invention provides pharmaceutical compositions containing substances that lead to express, activate or modulate protein, wherein the protein is selected among intravital redox system regulating proteins, ATP synthetases, glyceraldehyde 3-phosphate dehydrogenases, 14-3-3 proteins, phosphatidylethanolamine binding proteins, and the like. Preferably, such a substance includes FTS nonapeptide, which is so-called serum thymic factor. The pharmaceutical compositions of the present invention are useful as drugs that can control oxidative stresses by administering from outside the body.
