Objectives: Samjunghwan has been known to be effective for the treatment of obesity. To show the effectiveness of Samjunghwan in a more scientific way, Samjunghwan extract was prepared and evaluated in high-fat diet rats by measuring the changes of body weight and lipid metabolism as described below. Methods: 245 g of crushed Samjunghwan was extracted with methyl alcohol. The extract was evaporated under reduced pressure to give 21.8 g. For 30 days, the control group rats were given a high fat diet, while the test group rats were given a high fat diet plus Samjunghwan extract. The normal group rats were given a normal diet. 50 mg of Samjunghwan extract per 1 kg of body weight was added to the diet for the test group rats. Results: The control group rats on a high fat diet gained weight by about 27-28% as compared to the normal group, whereas the test group rats on a high fat diet plus Samjunghwan extract lost weight about 6-8% as compared to the control group. A significant increase of liver weight caused by a high fat diet was also inhibited by the same Samjunghwan extract administration. Similar inhibitory effects on the food intake and on the epididymal adipose tissue weight were observed in the high fat diet rats by the administration of Samjunghwan extract. Serum and liver total lipid levels in the control group on a high fat diet increased significantly as compared to the normal group, whereas their serum and liver levels increased less on a high fat diet plus Samjunghwan extract administered test group than the control group. Impressively, serum leptin levels in the test group decreased almost to the level of the normal group, which was well in accordance with the decreased fat contents in the test group rats. Furthermore, the activities of hepatic acetyl-CoA carboxylase and fatty acid synthetase were increased in the control group, while their activities in the test group on a high fat diet plus Samjunghwan extract decreased nearly to the levels of normal group rats on a normal diet. Conclusions: These results showed that the obesity caused by a high fat diet was effectively inhibited the administration of Samjunghwan extract. Our results also showed that the abnormal lipid metabolism caused by a high fat diet was effectively cured by the administration of Samjunghwan extract.

Objectives : Macrophage has an important innate defense role in the immune system. When we are infected with pathogens, macrophage ingests them through phagocytosis or endocytosis, and then secretes many cytokines, such as IL-1, IL-6 and $TGF{\alpha}$, which are regulators of immune responses. The aim of this study is to determine how Samjunghwan effects the expression of cytokine and other immune-related genes in macrophages. Methods : Cells were treated directly with Samjunghwan and/or LPS at regular intervals. Total RNA of cells was isolated using TRIzol reagent, and the changes in cytokine gene expressions were investigated using RT-PCR, western blot and ELISA. Results : $IL-1{\alpha},\;IL-1{\beta}$ and COX-2 genes were inducibly expressed specifically by Samjunghwan in macrophage. Especially, $IL-1{\beta}$ gene was induced most strongly by treatment with Samjunghwan. Over time, treatment with Samjunghwan showed that the expression levels of $IL-1{\alpha}\;and\;$IL-1{\beta}$ genes increased from 1 to 4h, and then decreased from 4 to ISh. However, the expression level of COX-2 gene increased continuously up to 11h. $IL-1{\alpha},\;IL-1{\beta}$ and COX-2 genes were expressed synergistically by a simultaneous treatment of both Samjunghwan and LPS in macrophages. Secretion levels of translated $IL-1{\beta}$ increased continuously up to 11h. Conclusions : Though this study is only a start in the investigation of the efficasy of Samjunghwan, these results suggest that Samjunghwan has positive effects on immune responses.

Objectives : Peroxynitrite $(ONOO^-),\;{\cdot}O_2^-$ and nitric oxide (NO) are cytotoxic species that can oxidize several cellular components such as proteins, lipids and DNA. It has been implicated in the aging process and age-related disease such as Alzheimer's disease, rheumatoid arthritis, cancer and atherosclerosis. The aim of this study was to investigate $ONOO^-$ scavengactivities, and that of its precursors, NO and ${\cdot}O_2^-$ of Samjunghwan. Methods : To investigate $ONOO^-,\;NO,\;{\cdot}O_2^-$ scavenging activities, fluorescent probes, namely 2',7'-dichlorodihydrofluorescein diacetate (DCFDA), 4,5-diaminofluorescein (DAF-2) and dihydrorhodamine 123 (DHR 123) were used. Results : Samjunghwan markedly scavenged authentic $ONOO^-,\;{\cdot}O_2^-$ and NO. It also inhibited $ONOO^-$ induced by .02' and NO which are derived from SIN-I. Furthermore, Samjunghwan inhibited $ONOO^-$, ${\cdot}O_2^-$ and NO generation in LPS-treated ICR mouse kidney postmitochondria. Conclusions : These results suggest that Samjunghwan is an effective $ONOO^-,\;{\cdot}O_2^-$ and NO scavenger, and that this substance has a potential role as an inhibitor of aging process, and in therapy against age-related diseases.

본 연구에서는 3T3-L1 전지방세포를 이용하여 발효 삼정환의 지방 분화 억제 효과를 확인하고자 하였다. 삼정환을 5가지 주요 유산균으로 각각 발효시킨 후, Oil Red O 염색법으로 지방세포 분화 억제 여부를 알아보고, 이의 기전을 알기 위해서 지방생성에 핵심적인 역할을 하는 transcription factor 및 지질 조절 효소의 유전자 발현량을 비교하여 보았다. Oil Red O 염색 분석에서는 Lactobacillus plantarum, Enterococcus faecium으로 발효한 삼정환에서 지방구 수의 감소를 확인할 수 있었다. 또한 transcription factor로 $C/EPB{\alpha}$, $PPAR{\gamma}$, UCP-2 및 콜레스테롤 조절과 관련된 효소인 HMG-CoA reductase의 4가지 유전자 발현 정도를 분석하였는데, 발효시키지 않은 삼정환의 경우 농도가 $100{\mu}L/mL$ 이상일 때 네 가지 항목에서 억제 효과를 나타냈으며, 발효시켰을 때는 유산균의 종류에 따라 효과 억제효과가 있었는데, Lactobacillus plantarum으로 발효한 삼정환이 효과가 가장 좋은 것으로 나타났다. Lactobacillus plantarum으로 발효한 삼정환은 동일 농도의 발효하지 않은 삼정환과 비교했을 때, Oil Red O 실험에서 염색된 지방구 수가 더욱 감소하였으며, $PPAR{\gamma}$, UCP-2, HMG-CoA reductase의 경우 농도가 $200{\mu}L/mL$일 때 각각 35%, 57%, 54%로 5가지 발효 삼정환 중 가장 높은 억제율을 나타내었다. 이에 지방분화 억제 효과를 가진 삼정환을 발효시키면 그 효과가 더욱 증가하는 것으로 나타났는데, 특히 Lactobacillus plantarum으로 발효한 삼정환은 $PPAR{\gamma}$, UCP-2, HMG-CoA reductase의 유전자 발현조절을 통해 지방 분화를 억제시키는 것으로 밝혀져 발효 삼정환은 항비만 혹은 항고지혈증 약물로 개발 가능성이 있는 것으로 사료된다.

본 연구에서는 삼정환의 혼합추출물과 개별추출물을 비교하여 항산화에 중요한 역할을 하고 있는 총 페놀 함량과 DPPH 자유라디칼 소거능 및 $TNF{\alpha}$의 유전자발현변화를 분석하였고, 항비만과 지질대사개선에 밀접한 요소인 AMPK-${\alpha}1$, HMG-CoA reductase, $PPAR{\gamma}$의 유전자 발현변화와 3T3-L1세포에서 Oil red O 실험을 하여 세포 내 지방구 함량의 변화를 살펴보았다. DPPH 자유라디칼 소거능은 두 군에서 큰 차이를 보이지 않았으며, 3T3-L1세포의 세포생존율은 삼정환의 혼합추출물과 개별추출물에서 모두 $200{\mu}g/ml$의 농도에서 높은 생존율을 보였다. 총 페놀함량 역시 개별추출물에서 더욱 많이 나타난 것을 알 수 있었으나, 종합적으로 항산화능력은 혼합추출물과 개별추출물이 유사한 것으로 나타났다. 비만과 관련성 있는 지질대사와 관련된 지표들을 분석해본 결과, Oil red O staining에서 혼합추출물을 처리한 군은 대조군과 큰 차이를 보이지 않은 반면, 개별추출물에서 지방구의 수가 감소한 것을 확인하였고, 항비만 효과에 주요한 타깃 유전자로 알려져 있는 AMPK-${\alpha}1$과 $PPAR{\gamma}$ 모두 혼합추출물에 비해 개별추출물에서 유의성 있는 변화를 확인하였다. 지질대사를 활성화시키는 HMG-CoA reductase 역시 유의성 있는 효과는 확인하지 못했으나 개별추출물에서 더욱 감소된 것을 알 수 있었다. 종합적으로, 삼정환을 혼합한 상태로 추출을 한 것보다 개별 약재를 추출한 것을 혼합하여 사용한 개별추출군이 항산화 및 항비만 효과에 더 나은 효능이 있는 것을 확인하였고, 이는 기존 환제의 제형으로 사용하던 약재의 실험에서 추출방법 및 제형에 더욱 심도 있는 연구가 필요하다는 것을 시사하였다.
