The comparison of histological effects of musk containing and civet containing WooHwangChungSimWon on the cerebral ischemia

Mongolian Gerbil의 뇌허혈 유발에 따른 뇌조직 손상에 있어서 사향 함유 우황청심원액과 영묘향 함유 우황청심원액의 조직학적 효능 비교

WooHwangChungSimWon is a traditional prescription for treating with hypertension, arteriosclerosis, coma, and stroke in China, Korea, and Japan. In the new presciption of WooHwangChungSimWon, the covet is substituted for the musk, the major component of WooHwangChungSimwon, because of the prohibition law about the musk. We have made a comparative study of the effects on the ischemic damage between the musk containing and civet containing WooHwangChungSimWon. In order to investigate the effects of WooHwangChungSimWon on the ischemic damage, each samples were administrated for 12 days, ischemia was induced for 10 minutes at 7th day, and immunohistochemistry was performed in the region of hippocampus of mongolian gerbils. According to the result of immunohistochemistry, the survival rates of neuroal cells in the hippocampal CA1 region are 37.8% in the high dose of musk containing WooHwangChungSimWon (HM-WHCSW) administrated group, 27.8% in low dose of civet containing WooHwangChungSimWon (LC-WHCSW), and 35.5% in high dose of civet containing WooHwangChungSimWon (HC-WHCSW) administrated group. These survial rates were significantly different from the survival rate of sham control group (14.4%). The results suggest that all the samples except the low dose of musk containing WooHwangChungSimWon (LM-WHCSW) have protective or preventive effects on cerebral ischemia.
