Objectives : The cosmeceutical activity of Cuacuta japonica Choisy were investigated for cosmetics industrial application. Methods : Cosmeceutical activities include antioxidant, tyrosinase inhibition effects and nitrite-scavenging ability were examined through the Cuacuta japonica Choisy Results : The result were obtained as follows : The electron donating ability of water and ethanol extract was 69.5%, 78.3% at 1,000ppm. In SOD-like activity, water extract showed low effect, but ethanol extract scored 63.4% at 1,000ppm. In inhibition activity of xanthine oxidase, water extract showed low effect, which is 27.2% at 500ppm, in contrast to ethanol extract high effect: 99.5% at 500ppm, in nitrite-scavenging ability test, 500ppm of C. japonica Choisy water extract showed the effect of 51.3%, while 500ppm of C. japonica Choisy ethanol extract showed the effect of 72.7%. From the test of inhibitory effect of tyrosinase, both water and ethanol extract showed insufficient inhibitory rate. Conclusion : According to all the test results that have been given, it is possible that the extract of C. japonica Choisy can be used as a new natural material of the cosmeceutical industry.

Objectives : The purpose of the present study is to observe the neuroprotective effect of the $NeuBo153^{\circledR}$ on transient focal cerebral ischemia in rats. Methods : $NeuBo153^{\circledR}$ was made by mixing the herbs, mainly the root of Panax ginseng, the root of Rehmannia glutinosa and Poria cocos, the stem bark of Acanthopanax senticosus, the root of Scutellaria baicalensis and Mel, and heating for 96 hours. Transient Focal cerebral ischemia (2 h of ischemia, 22 h of reperfusion) was induced by intraluminal suture method with SD rats. Sensory motor function was tested by rotarod test, prehensile traction test, beam balance test and foot fault test at 24 h after ischemia. The brain slices were stained by 2% 2, 3, 5-triphenyltetrazolium chloride and the infarct volume was measured by graphic analyzer at 24 h after ischemia. Results : $NeuBo153^{\circledR}$ treated group did not show significant differences compared with vehicle treated group in body temperature. Oral administration of $NeuBo153^{\circledR}$ reduced brain infarct volume by 29.7% compared with vehicle treated group. $NeuBo153^{\circledR}$ also showed protective effects on sensory motor functional deficits. Conclusion : $NeuBo153^{\circledR}$ treatment reduced brain damage and improved functional deficits induced by MCAo. It showed neuroprotective effects even when treatment was relayed 2 h after injury. Further research is required to evaluating long term functional recovery am accurate therapeutic range and mechanisms.
