Non-alcoholic fatty liver disease (NAFLD) is common in obesity. However, weight reduction alone does not prevent the progression of NAFLD to end-stage disease associated with the development of cirrhosis and liver disease. In a previous experiment, 50% ethanol extract of Acanthopanax senticosus stem bark (ASSB) was found to reduce body weight and insulin resistance in high fat diet-induced hyperglycemic and hyperlipidemic ICR mice. To evaluate the anti-steatosis action of ASSB, insulin-resistant ob/ob mice with fatty livers were treated with ASSB ethanol extract for an 8 week-period. ASSB ethanol extract reversed the hepatomegaly, as evident in reduction of % liver weight/body weight ratio. ASSB ethanol extract also specifically lowered circulating glucose and lipids, and enhanced insulin action in the liver. These changes culminated in inhibition of triglyceride synthesis in non-adipose tissues including liver and skeletal muscle. Gene expression studies confirmed reductions in glucose 6-phosphatase and lipogenic enzymes in the liver. These results demonstrate that ASSB ethanol extract is an effective treatment for insulin resistance and hepatic steatosis in ob/ob mice by decreasing hepatic lipid synthesis.

The effects of the water extract from the stem bark of Acanthopanax senticosus were evaluated on hyperlipidemic rats induced by lipid rich diet or poloxamer-407. The water extracts, when administered orally for 3 consecutive days in hyperlipidemic rats induced by poloxamer-407 (1 ml of 30%), was found to cause a significant decrease in plasma cholesterol and triglyceride concentrations. The water extracts, when treated orally for 5 consecutive days also showed a significant inhibition of serum total cholesterol and triglyceride level in rats treated with lipid rich diet (15% cholesterol, 1% sodium cholate and 84% com oil). HDL-cholesterol, however, was increased significantly.

We previously reported that the phytoprotein extracted from Acanthopanax senticosus (PA) had anti-carcinogenic anti-metastatic activity via increase of inhibition of gap junctional intercellular communication. In the present study investigated the immunomodulatory mechanism of phytoprotein isolated from the stem bark of Acanthopanax sentic (PA). PA was found to significantly stimulate macrophages producing TNF-α and IL-1β in vitro. It also showed tumori activity indicating that PA had the ability to stimulate macrophage directly. Moreover, PA induced the CDB/sup +/ CTL cy responses to recognize antigen on the B16-BL6 melanoma cells. Treatment of PA with B16-BL6 melanoma cells increased the proliferation of splenocytes compared with untreated control. These results demonstrate that PA immunomodulatory activity suggesting a useful anti-tumor agent applicable to treatment and prevention of cancer.

가시오가피에서 Polyacetylene 성분 중 falcarinol을 탐색하기 위해 TLC, HPLC/PDA, GC, GC/MS를 이용하여 falcarinol 표준품과 소분획물 사이의 비교 분석을 통하여 가시오가피에서 falcarinol을 동정하였다. 가시오가피 추출물을 silica gel column상에서 용매의 극성차이에 의해 6개의 분획물을 얻었고, 6개의 분획물과 falcarinol 표준품과의 TLC 상에서 전개시킨 결과 fraction 6 분획물에서 falcarinol과 동일 band의 물질을 분리하였다. Fraction 6의 분획물과 falcarinol 표준품을 HPLC/PDA로 분석한 결과 falcarinol 표준품의 peak와 동일 retention time의 peak를 fraction 6에서 분리하여 200-340nm 상에서 UV spectrum을 관찰한 결과 동일한 UV spectrum pattern을 보이는 것을 확인하였다. 이는 전형적인 polyacetylene 화합물의 UV spectrum pattern이었으며, 기존에 보고된 falcarinol의 UV spectrum과도 동일하였다. GC로 TMS 유도체화 전,후의 retention time을 확인한 결과 표준품과 fraction 6에서 동일한 결과를 보였다. TMS 유도체화 후에는 7.5분에서 8.5분으로 약 1분 정도 retention time이 증가하였고, detection 감도 또한 증가하였다. Falcarinol 표준품과 fiaction 6 분획물을 TMS 유도체화 후에 GC/MS로 mass fragment ion을 분석한 결과 표준품과 동일한 경향을 보였고 이는 기존의 보고와도 일치하였다(16). 본 실험결과들로 미루어 가시오가피에도 polyacetylene 성분인 falcarinol 존재하는 것으로 확인되었다.

두릅나무과 식물 6종의 잎으로부터 2개의 공통적인 superoxide dismutase(SOD) isoenzyme이 구분되었다. 이들 공통적인 isoenzyme(SOD 4와 SOD 6)의 패턴은 오갈피속 식물 중에서 민가시오갈피나무(A. senticosus for. inermis) 잎에서 가장 다양하였고, 그 활성은 섬오갈피나무(A. koreanum) 잎에서 가장 높았다. 그리고 SOD 4와 SOD 6은 $H_2O$$_2$와 KCN에 의한 선택적 저해로부터 각각 Fe-SOD와 CuZn-SOD인 것으로 밝혀졌다. 또한, SOD isoenzyme의 패턴은 섬오갈피나무의 성숙한 잎과 수피, 근피에서 차이가 없었으나 그 활성은 조직별로 차이가 나타났으며, Fe-SOD는 근피에서, CuZn-SOD은 잎에서 상대적으로 높게 나타났다. 그리고, CuZn-SOD나 Fe-SOD 모두 30-4$0^{\circ}C$에서 높은 활성 을 나타내었으나 그 이상의 온도에서는 활성이 저해되었다.

1. The Korean Acanthopanax genus includes 12 kinds consisting of 9 species and 3 forma. 2. The Korean Oga-pi which is on market sale has been used as bark for the medicinal purpose, and Oga-pi shall use Radicis Cortex. That is why it is basic rule that herbalogy shall use Radicis Cortex. 3. The origin of Oga-pi on sale is Acanthopanax sessiliflorum forma chungbunensis C.S. Yook. 4. $C_{HUNG}\;and\;N_AKAI'S}$ report on A. koreanum told us that there are brown hair on the mid-leaf junction, but in addition to it, our investigation was resulted in the fact that there are thorn along mid-rib sometimes. 5. 2 kinds of new forma are similar to A. sessiliflorum, but are different in the view-point of chemotaxonomy, compared with A. sessiliflorum. In its morphology, we can find some difference between 2 kinds of new forma and A. sessiliflorum. Our effort of examination on documents tell us that the all plants growing in the central part of our country is A. sessiliflorum forma chungbunensis C.S. Yook. The one which has thorn on both side among the plants collected in Mt. Dukyu, is called A. sessiliflorum forma nambunensis C.S. Yook. 6. A. sessiliflorum is growing in the southern part in Korea, and most Chungbu Oga-pi A. sessiliflorum forma chungbunensis in the central part of our country. For the convenience of our study, the key of Korean Acanthopanax plant is classified into, I-IV, as shown on the following items: I. No hair on both side of leaf A. Flower stalk is longer than petiole, and there are thorn under the petiole (5-7 stigma).${\cdots}A.\;sieboldianum$. B. Flower stalk is longer than petiole, or same length. The serration lie down, and the stem has short thorn (stigma is divided into 3 part).${\cdots\;\cdots}A.\;seoulense$ II. There are a lot of thorn or hair on back of leaf. A. A lot of thorn and hair on the vein of leaf back, and a number of small thorn on petiole.${\cdots}A.\;chiisanensis$. B. There are thorn on the vein of leaf back.${\cdots\;\cdots}A.\;sessiliflorum\;forma\;chungbunensis.$ III. There are hairs on both side of leaf. A.

There are thick hairs on junction of main vein on back of leaf.${\cdots\;\cdots}A.\;koreanum.$ D. There are brown hairs on vein of leaf back, and brown hairs on small petiole.${\cdots\;\cdots}A.\;rufinerve.$ E. There are shrunk hairs in grey-brown on back of leaf, and tense hairs on new branch (one stigma).${\cdots\;\cdots}A.\;divaricatum.$ IV. There are long thorn, just like needles, on the stem and petiole. A. Long needle grows on whole stem tensely, and long needles on petiole.${\cdots\;\cdots}A.\;senticosus.$ B. There are no needles, just like needles aid hairs on petiole, and needles grow on the stem thinly.${\cdots\;\cdots}A.\;asperatus.$ C. There are no needle on small brarch, leaf and inflorescence are larger than A. senticosus. ${\cdots\;\cdots}A.\;senticosus\;forma\;inermis.$.

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.
