BRAIN CELL OR NERVE CELL-PROTECTING AGENT COMPRISING GINSENOSIDE Rb1

摘要

PROBLEM TO BE SOLVED: To obtain the subject compound for accelerating expression of cell death suppressing gene product Bcl-xL by containing ginsenoside Rb1. SOLUTION: This protective agent for brain cells and nerve cells is brought to contain ginsenoside Rb1 (a compound expressed by the formula). As a medicinal composition, a formulation for intravenous injections is preferable. The concentration of ginsenoside Rb1 is preferably a low concentration, particularly the concentration of an extracellular fluid is <=1 ng/ml, preferably <=1 pg/ml, more preferably <=100 fg/ml. A dose per day is usually >=0.1 mg, preferably 1 mg to 1 g, more preferably 10 mg to 0.1 g.
