Objectives : This study was aimed at examining significant curative effects of Cupping therapy on Cerebral infarction patients with hyperlipidemia. Methods : The subjects in this study were fifty-two patients visited or admitted to Dong-seo Oriental Hospital who broke out with Cerebral infarction from March 2007 through February 2008, with high total cholesterol(240mg/$d\ell$ above) or high triglyceride(200mg/$d\ell$ above) or low density lipoprotein(160mg/$d\ell$ above) Before prescription, they were tested for total cholesterol, triglyceride, low density lipoprotein with fasting and were then rescribed the cupping therapy for 4 weeks(take an average ten times), after which they were retested for total cholesterol, triglyceride, low density lipoprotein. Results : 1. In the high total cholesterol group(triglyceride and low density lipoprotein are normal), statistical significance of total cholesterol changes was recognized before and after the treatment. 2. In the high triglyceride group(total cholesterol and low density lipoprotein are normal), statistical significance of triglyceride changes was recognized before and after the treatment. 3. In the high low density lipoprotein group(total cholesterol and triglyceride are normal), statistical significance of triglyceride changes was recognized before and after the treatment. 4. In the high total cholesterol and high triglyceride group(low density lipoprotein is normal), statistical significance of total cholesterol changes was recognized before and after the treatment. But, triglyceride changes was not that. 5. In the high total cholesterol and high low density lipoprotein group(triglyceride is normal), statistical significance of total cholesterol and low density lipoprotein changes were recognized before and after the treatment. 6. In the high triglyceride and high low density lipoprotein group(total cholesterol is normal), statistical significance of triglyceride changes was recognized before and after the treatment. But, low density lipoprotein changes was not that. 7. In the high total cholesterol and high triglyceride and high low density lipoprotein group, statistical significance of total cholesterol changes and low density lipoprotein changes were recognized before and after the treatment. But, triglyceride changes was not that. Conclusions : Cupping therapy decreased total cholesterol in whole hyperlipidemia group including high total cholesterol.

This study was performed to evaluate the antioxidant activity of silymarin against human low density lipoproteins(LDL) oxidation. Silymarin extracted from Silybum marianum was successively purified with solvent fractionation and followed by silica gel column chromatography. The active substances were separated by HPLC and the isolated active substances, silymarin were identified by IR, NMR, GC-MS as silymarin. Silymarin inhibited at the 5 $\mu$M Cu2+-mediated oxidation of human low density lipoprotein (LDL) in a dose dependent manner. Silymarin completely inhibited LDL oxidation at 50 $\mu\textrm{g}$/$m\ell$ concentration. These findings suggest that silymarin may protect LDL against oxidation in atherosclerotic lessions.

This study was initiated to antioxidant activity of silybin on oxidation of human low density lipoproteins(LDL). Siltbin was extracted from Silybum marianum by the combination of fractionation and it was futher purified by silica gel column chromatography, and isolated active substances were identified silybin by IR, NMR and GC-MS. siltbin inhibited the ozidation of human low density lipoprotein(LDL) mediated by 5$^{\mu}$m CU $^{2+}$ ion in a dose dependent manner. LDL oxidation by congugated dines formation was completely inhibited by silybin at a concentration of 5$^{\mu}$M. The results provide a possibility that silybin might protect LDL against oxidation in atherosclerotic lessions.

Cirsium japonicum water extracts has been used to treat vascular related diseases. We have previously reported that Cirsium japonicum extracts activated estrogen receptors. It is widely known that estrogen increases the high density lipoprotein cholesterol and decrease the low density lipoprotein cholesterol on the lipid profile. But effects of Cirsium japonicum on lipid profile are not reported yet. Therefore, we have studied the effects of Cirsium japonicum on the lipid content in ovariectomized rats. Thirty Sprague-Dawley (SD) rats of $210{\pm}20\;g$ were studied for 10 weeks. The rats were divided into five groups; (I) sham, no ovariectomized rats plus olive oil, (II) ovariectomized rats plus olive oil, (III) ovariectomized rats plus 0.5 mg/kg $17{\beta}$-estradiol (E2) in olive oil, (IV) ovariectomized rats plus 0.5 mg/kg Cirsium japonicum in olive oil, and (V) ovariectomized rats plus 5 mg/kg Cirsium japonicum in olive oil. Treatment with Cirsium japonicum or E2 induced significant reduction in total cholesterol, low density lipoprotein cholesterol/total cholesterol, total cholesterol/high density lipoprotein cholesterol and low density lipoprotein cholesterol/high density lipoprotein cholesterol compared to control group as well as increase in uterine weight. However, changes in triglycerides levels were different. Our results suggest that Cirsium japonicum is functionally similar to E2 in vivo as well as in vitro.

본 연구는 유용식물로부터 DPPH free radical scavenger및 사람의 low density lipoprotein(LDL)의 산화에 대한 항산화 효과를 조사하기 위하여 25종의 식물로부터 메탄올로 추출하여 조사하였다. 각종 유용식물 중 항산화 활성은 우수한 달맞이꽃이 가장 높았으며 다시 메타놀로 추출하여 조사한 결과 $\alpha$-tocopherol과 항산화능이 거의 비슷하였다. 메타놀 추출물을 ethylacetate로 추출한 획분이 항산화 활성이 높았으며 ethylacetate 층 중 acidic soluble 획분을 다시 분리한 후 Sepadex LH-20 column chromatography로 추출한 결과 Fraction F-2가 전자공유능이 가장 높았다. 따라서 항산화 활성이 높은Fraction, F-2의 구조를 동정한 결과 3,4-dihydroxybenzoic acid와 3-hyoxycinnamic acid로 확인되었다.

흰쥐의 lipoprotein을 제거한 혈장내의 지질전이 활성도와 지진전이를 저해하는 활성도를 측정하였다. 지질전이 활성도의 측정은 방사성 동위원소가 함유된 cholesteryl ester (CE)와 triglyceride (TG) 로 표지된 인체의 혈장 low density lipoprotein 으로부터 high high density lipoprotein(HDL) 으로 전이되는 방사성 동위원소의 양을 측정하여 계산하였다. 지질전이 저해 활성도는 정제한 인체 혈장 지질전이 단백질에 의한 지질전이를 저해하는 정도로서 측정하였다. 흰쥐의 혈장에는 지질전이 활성도가 거의 없으나, 지질전이를 저해하는 활성도는 존재하였다. 지질전이 저해정도는 측정용액내의 lipoprotein 양이 증가할수록 감소하였다. 일반적으로 흰쥐의 HDL은 인체의 HDL에 비하여 CE 의 함량은 높으며 TG의 함량은 낮다. 흰쥐의 혈장에 인체의 혈장으로부터 정제한 지질전이 단백질을 가하여 37$^{\circ}C$에 24시간 두었을 때, HDL 로부터 very low density lipoprotein (VLDL)으로 CE가 이동하여 VLDL 의 CE 함량이 4배나 증가하였다. 반면에 VLDL로부터 HDL$_2$로TG가 이동하여 $HDL_2$의 함량은 TG함량은 9배나 증가하였다. 이와같은 현상은 흰쥐의 혈장 Lipoportein이 지질전이의 기질로서의 결함은 없음을 보여준다. 따라서 지질대사에 관한 실험에서의 흰쥐에 의한 실험결과의 해석에는 인체 혈장에 비하여 혈장에는 lipoprotein사이의 중성지질의 전이나 교환이 거의 없다는 특성이 고려되어야한다.

This study was undertaken to evaluate antioxidative activities of substances isolated from marine resources against human low density lipoprotein (LDL). Methanol-water extract(80 : 20, v/v) of Sargassum ringgoldianum had the highest antioxidant activity and the active substance was purified by silica gel column chromatography by eluting chlorform : methanol mixture (80 : 20 v/v). The active fraction was seperated to several spots on the TLC in chlorofrom : methanol (10 : 1, v/v) mixture. Antioxidative activity of band 4 of fraction 2 on TLC was highest than that of $\alpha$-tocopherol against human LDL oxidation by the method of thiobarbituric acid reactive substance (TBARS). The band 4 of fraction 2 inhibited the copper mediated oxidation of human LDL with almost completely at 1 or 2 mg/ml.

Antioxidative activity of fraction extracted from cultivation of Aspergillus sp. A-5 against oxidation of human low density lipoprotein(LDL) was investigated. Fractions of Aspergillus sp. A-5 cultivation was sucessively purified with ethyl acetate and silica gel column chromatography. The concentration of fraction 4 inhibited Cu$^{2+}$-induced oxidation of LDL almost completely. Band 3 isolated by the further purification of fraction 4 was higher than that of same concentration of $\alpha$-tocopherol, BHA and BHT. The elcetrophoretic mobility of oxidized LDL by addition of Band 3 was faster than that of native LDL, but slower than that of oxidzed LDL. It is concluded that fraction of Aspergillus cultivation contained antioxidants with the capacity to inhibit oxidative modification of LDL.
