PROMOTER FOR CEREBRAL BLOOD VESSEL REPRODUCTION/ RESTRUCTURING AND INHIBITOR AGAINST SECONDARY NERVE TISSUE SECONDARY DENATURATION COMPRISING GINSENOSIDE Rb1

摘要

PROBLEM TO BE SOLVED: To obtain the subject composition capable of protecting a damaged brain for a long period of time by showing excellent promoting action on cerebral blood vessel reproduction and restructuring by intravenous administration after apoplexy and inhibiting secondary denaturation of nerve tissue by making the composition include ginsenoside Rb1. SOLUTION: This parenteral administration preparation contains ginsenoside Rb1 (compound of the formula) or its metabolic product. Preferably the parenteral preparation contains the active ingredient in a low concentration. To be more concrete, the extracellular fluid concentration is preferably <=1 ng/ml, more preferably <=1 pg/ml, further preferably <=100 fg/ml. The daily dose of the medicine composition for human apoplexy patient or spinal cord injury patient is >=0.1 mg, preferably >=1 mg, more preferably >=10 mg and its upper limit is <=1 g, preferably <=0.1 g.
