COMPOSITIONS FOR PREVENTING OR TREATING BRAIN NEURONAL DISEASES AND IMPROVING RECOGNITION FUNCTION

摘要

PURPOSE: Compositions for preventing or treating brain neuronal diseases and improving recognition function are provided, thereby effectively preventing or treating brain neuronal diseases with less of side-effects. CONSTITUTION: The composition for preventing or treating brain neuronal diseases comprises (a) a pharmaceutically effective amount of silk peptide produced by decomposition of silk protein; and (b) pharmaceutically acceptable carriers, wherein the silk protein is silk sericin or silk fibroin; the decomposition of silk protein is carried out by using calcium solution such as calcium chloride, acid hydrolysis, protein decomposing enzyme such as thermoase, flavourzyme, sumizyme, protamex and protin and a combination thereof; and the average molecular weight of the silk peptide is 300 to 100,000 dalton. The composition for improving recognition function comprises (a) a pharmaceutically effective amount of silk peptide produced by decomposition of silk protein; and (b) pharmaceutically acceptable carriers.
