Erythrocyte stem cell differentiation promoter and / or proliferation promoter, and use of methionine for preventing or treating senile anemia and a composition containing methionine

摘要

Since anemia is frequently observed with aging, the first task is to develop a therapeutic agent effective in preventing senile anemia. Furthermore, since aging will progress in the future, it is a second object to provide an inexpensive and effective anti-aging agent with low side effects. It is a third object to provide a therapeutic agent effective for anemia caused by bone marrow function suppression, specifically, anemia as a side effect of administration of an anticancer drug. The inventor of the present application includes a simple substance of methionine (Met), an amino acid composition composed of one or more selected from methionine (Met), glycine (Gly), serine (Ser), and threonine (Thr). Ile, Trp, Thr, Val, His, Phe, Lys and Leu, (2) Ile, Thr, Val, His, Lys and Leu, (3) Trp, Thr, His, Phe and Lys, (4) Ile, An agent containing an amino acid mixture selected from Trp, Thr, Val, Phe, and Leu as an active ingredient has been found for the first time to have the ability to improve and recover senile anemia. Agent and cell antiaging agent could be provided.
