Objectives Objective of this study is to investigate the role of paraspinal muscles by examining the correlation between slip percentage (SP) of spondylolisthesis and fatty infiltration of lumbar paraspinal muscle. Methods Retrospective analysis was performed on 45 patients diagnosed with spondylolisthesis based on medical records. Using T2-weighted axial magnetic resonance imaging, cross-sectional areas (CSAs) of psoas major (PM), multifidus (MU) and erector spinae (ES) were calculated and divided by CSA of lower level vertebral body (VB). SP was measured using sagittal T2-weighted images. Correlation of SP with muscle relative cross-sectional area (RCSA) and muscle fatty infiltration by Goutallier classification was respectively analyzed using Spearman correlation. Statistic assessment conducted by Wilcoxon signed rank test and paired t-test using program GraphPad prism 5 (GraphPad Software, Inc., San Diego, CA, USA). Results Spondylolisthesis forward slip percentage by Taillard's method was negatively associated with both side MU RCSAs. No significant correlation was found between PM RCSA, ES RCSA and SP. Forward slippage was significantly correlated with fatty infiltration of lumbar paraspinal muscle measured by Goutallier classification. Conclusions This study is to understand the role of paraspinal muscle affecting spinal instability by investigating correlation between statistical deviation of lumbar muscle characters (RCSA, fatty infiltration of lumbar muscle) and SP. We found that spondylolisthesis SP is positively related to fatty infiltration of lumbar paraspinal muscle. and is negatively associated with both side MU RCSAs.

Objectives The purpose of this study is to help improve the management of traditional Korean medical(TKM) clinics and the policies for supporting them, by conducting a survey of the practitioners of TKM. Methods Stratified sampling was conducted based on regional location, and 700 samples were selected in a random manner from the membership list. The questionnaire was delivered and returned by mail. The survey was conducted between 20 July and 31 August 2010. A total of 177 questionnaires (recovery rate: 25.28%) were recovered and analyzed for the study. Results 1. The the survey indicate that the overall size of TKM clinics has fallen compared with previous survey, while the average number of beds per clinic has remained unchanged at 7.9. The sale of medicine as a proportion of total monthly sales has increased. 2. There has been no change in the composition of clinical staff as there are three nursing assistants. Although the average daily number of patients to clinics has remained at around 33.90 compared with ten years ago, the number of patients requiring seeking acupuncture treatment has increased while the number of those treated with medication has decreased. 3. Clinicians in TKM have indicated their preference for a binary system that separates TKM from western medicine (57.4%). The respondents do not favor the separation of dispensary from medical practice (81.5%), marks of origin for medicinal herbs (68.9%), disclosure of the prescriptions (67.2%), and the overseas expansion of Korean medical services (70.4%). However, they indicated that they are very much in favor of being granted the authority to employ and give orders to medical technicians (96.0%). 4. The respondents selected Korea as the country that maintains a proper academic system for traditional medicine (45.5%), and are not in favor of opening Korea's traditional medicine market under an Free Trade Agreement(FTA) with China (72.7%). Conclusion The overall status of the management of TKM clinics has declined compared with the preceding decade. There has been only a slight change in clinicians' opinion of the related policies and regulatory issues.

Objective : This study was conducted to investigate antidiabetic effects of chunggugjang with medicinal herbal complex (CJ) in streptozotocin (STZ)-induced animal models. Method : STZ (65 mg/kg) was injected intraperitoneally to induce diabetes. Then rats were divided into 5 groups ; NG (normal diet + 0.9% saline), COS (STZ +saline 5 mL/kg), COB (STZ + fermented soybean(100 mg/kg), CJ 100/200 (STZ+CJ(100 and 200 mg/kg), CJ 300/600 (STZ+CJ(300 and 600 mg/kg). 4 weeks later, oral glucose tolerance test (OGTT) was performed. After sacrificing rats, serum levels of blood urea nitrogen (BUN), creatinine, aspartate amino transferase (AST), alanine amino transferase (ALT), total cholesterol (TC), and triglyceride (TG) were measured and histological changes were observed. Result : Body weight change and food efficiency ratio (FER) were decreased in the CJ 300/600 group than in the COS group. But, there was no change in water intake. Serum levels of glucose, AST, ALT and BUN were lower in the CJ 300/600 group than in the COS group. Also, TG, TC, and creatinine were decreased in the CJ 300/600 group than in the COS group. According to OGTT, 120 minutes postprandial glucose levels were lower in the CJ 300/600 group than in the COS group. In addition, administration of CJ extracts restored histopathological damage. Conclusion : The results suggest that CJ can be used as a functional material for diabetes treatment as it has the effect to improve pathological symptoms in STZ-induced diabetic rats.

Objectives There is few Korean medicinal studies about post-operation wound healing despite much effort for minimizing wound or post-op scar. The aim of this study is to evaluate the wound healing effect of Gyejibokryeong-hwan (Guizhifuling-wan, GBH) after skin suture. Methods < In vitro > We observed anti-oxidative and anti-inflammatory effect by using lipopolysaccharide (LPS)-treated RAW 264.7 cells. For anti-oxidation, we mesured the total amount of polyphenol, flavonoid, DPPH scavenging ability, ABTS scavenging ability and the value of ROS production, and for anti-inflammation, we mesured the amount of NO and pro-inflammatory cytokines ($TNF-{\alpha}$, $IL-1{\beta}$, IL-6). < In vivo > Thirty SD rats were divided into five equal groups (n=6, one normal, two controls and two experimentals). All groups except normal group were made a scar (around $1{\times}4cm^2$) in the back by the depth of the fascia and then sutured by a thread and needle. Normal group rats received no treatment at all. Control group rats were fed distilled water, and positive control group rats were percutaneously applied terramycin once in 2 days. GBH 200 group rats were orally medicated GBH 200 mg/kg, and GBH 400 group rats were orally medicated GBH 400 mg/kg per day for two weeks. We analyzed the blood samples (WBC, neutrophil, lymphocyte, monocyte, eosinophil), and the serums (TIMP-1, MMP-2, MMP-2. $PGE_2$, $TGF-{\beta}$, VEGF), and examined the wounded skin tissue histopathologically. Results < in vitro > 1. DPPH and ABTS scavenging activity was increased concentration-dependantly, and ROS production was significantly increased in GBH treated cells ($100{\mu}g/ml$). Therefore in this study, Gyejibokryeong-hwan appears to have the anti-oxidative. 2. NO production was significantly reduced in GBH treated cells ($100{\mu}g/ml$), and $IL-1{\beta}$ production was significantly reduced in GBH treated cells ($1{\mu}g/ml$). But, $TNF-{\alpha}$ and IL-6 did not show uneffective action. Therefore in this study, Gyejibokryeong-hwan did not show any significant effect on anti-inflammatory process. < in vivo > 1. Monocyte and neutrophil was significantly increased in GBH (200, 400) groups. WBC, lymphocyte and eosinophil did not show significant change. 2. TIMP-1, MMP-2, VEGF were significantly increased in GBH 400 group, $PGE_2$ was significantly reduced in GBH 400 group. $TGF-{\beta}$ was significantly increased in GBH (200, 400) groups, and MMP-9 was increased concentration-dependantly in GBH groups, but there was no significance. 3. In histopathological examinations, collagen was significantly increased and keratin was significantly decreased in GBH (200, 400) groups. Conclusions According to in vitro experiment, GBH appears to have the anti-oxidative effect and in vivo experiment, GBH stimulate the wound healing process hematologically and histopathologically. In conclusion, the results suggest that GBH promotes wound healing after skin suture.

겨우살이는 전통적으로 항암활성이 있는 약용식물의 하나로 알려져 왔고, 렉틴은 세포독성 및 면역자극 자극 활성을 가지는 대표성분으로 인정되고 있다. 한국산 겨우살이에 함유되는 렉틴은 유럽산의 그것과는 달리 galactose와 N-acetylgalactosamine(GalNAc) 특이성을 동시에 가지는 렉틴 성분인 KML인 것으로 나타났다. Sandwich ELISA법을 이용하여 각기 다른 종류의 숙주나무에서 유래된 5종의 겨우살이로부터 렉틴 함량을 비교한 결과, 숙주나무별 차이가 인정되어 밤나무 겨우살이는 참나무 겨우살이에 비하여 약 10배 많은 렉틴을 함유하고 있었다. L5178Y-ML25 lymphoma 세포에 약 90%의 세포독성을 나타내는 농도의 KML과 한국산 참나무 유래 겨우살이 추출물인 KM-100에 두 종류의 단일클론 항체(9H7-10 and 8B11-2C5)를 동시처리한 후 세포독성 중화효과를 조사한 결과, KML의 경우 약 10%, KM-110의 경우 약 30%의 세포독성을 보였다. 이러한 결과는 겨우살이에서 렉틴 외에도 세포독성을 가지는 다른 성분이 존재할 것으로 사료되었다. RAW 264.7 대식 세포주에 KM-110과 KM-110으로부터 렉틴이 제거된 분획인 LFKM-110을 자극시킨 결과, LFKM-110에서 $TNF-{\alpha}$ 및 IL-6와 같은 cytokine의 생산을 증진시키는 결과를 보였다. 따라서 KM-110에서 면역 세포를 자극하는 다른 성분의 존재하고 있음을 강하게 제시되었다.

Isolated rat adipocytes are well known to possess opposite pathways of lipid metabolism: lipolysis and ipogenesis. Both of the metabolism respond to various biologically active substances such as epinephrine, ACTH and insulin. Epinephrine and ACTH stimulate lipolysis and insulin accelerates lipogenesis. Recently, Korean red ginseng powder was found to contain adenosine and an acidic poptide which inhibited epinephrine-induced lipolysis and sl imulated insulin-mediated lipogenesis from added glucose. The acidic peptide is consisted mainly of glutamic acid and glucose. Ginsenosides Rb1 and Re inhibited ACTH-induced lipolysis in isolated rat adipocytes, while they did not affect insulinstimulated lipogenesis, Thus, all these substances extracted from Korean red ginseng exhibited selective modulations toward the opposite metabolic pathways in rat adipocyte; They inhibited the lipolysis but not the lipogenesis. We call these substances"selective modulators". Recently, we isolated a toxic substance named "toxohormone-L " from ascites fluid of patients with various malignant tumors. The toxohormone-L stimulated lipolysis in rat adipocytes and induced anorexia in rats. Both the lipolytic and the anorexigenic actions of toxohormone-L were found to be inhibited by ginsenoside Rb2 in Korean red ginseng. Based on these results, physiological signifi¬cances of these substances in Korean red ginseng were discussed. Pan ax ginseng is a medicinal plant long used in treatment of various pathological states including general complaints such as head ache, shoulder ache, chilly constitution and anorexia in cancer patients, There have been many pharmacological studies on Panax ginseng roots. Petkovllreported that oral administration of an aqueous alcoholic extract of ginseng roots decreased the blood sugar levtl of rabbits. Saito2lreported that Panax ginseng suppressed hyperglycemia induced by epinephrine and high carbohydrate diets. These findings suggest that Panax ginseng roots contain insulin-like substances. Previously, we demonstrated that gin¬seng roots contain an insulin-like peptide which inhibits epinephrine-induced lipolysis and stimulated insulin-mediated lipogenesis. In 1984, we suggested that such an insulin-like substance should be called a selective modulator4). Present investigation describes the details of the selective modulators in ginseng roots. During progressive weight loss in patients with various neoplastic disease, depletion of fat stores have been observed. The depletion of body fat during growth of neoplasms is associated with increase in plasma free fatty acids. Recently, we found that the ascites fluid from patients with hepatoma or ovarian tumor and the pleural fluid from patients with malignant lymphoma elicited fatty acid release in slices of rat adipose tissue in vitro. The lipolytic factor, named"toxohormone-L". was purifed from the ascites fluid of patients with hepatoma. The isolated preparation gave a single band on both disc gel electrophoresis and sodium dodecyl sulfate(SDS)-acrylamide gel electrophoresis in the presence of ${\beta}$-mercaptoethanol. Its molecular weight was determined to be 70,000-75,000 and 65,000 by SDS-acrylamide gel electrophoresis and analytical ultracentrifugation, respectively. Injection of toxohormone-L into the lateral ventricle of rats significantly suppressed food and water intakes. There was at least 5 hr delay between its injection and appearance of its suppressive effect. In the present study, we also tried to find a inhibitory substance toward toxohormone-L from root powder of ginseng.

적작약, 사간, 치자, 적복령, 승마 및 백출 등 6가지의 한약재로 구성된 사간탕은 동의보감에서 위완옹(胃脘癰)을 치료하는 처방으로 알려져 있으나, 항암 효능에 대한 구체적인 연구는 전혀 이루어진 바 없다. 본 연구에서는 사간탕의 항암활성 연구의 일환으로 AGS 인체 위암세포의 증식에 미치는 영향을 조사하였다. 본 연구의 결과에 의하면 사간탕 추출물 처리 농도의 증가에 따라 AGS 위암세포의 증식 및 생존율이 억제되었으며, 이는 apoptosis 유발에 의한 것임을 염색질 응축, DNA 단편화 및 annexin-V 염색 등을 통하여 확인하였다. 사간탕 추출물 처리에 의한 apoptosis 유발에는 pro-apoptotic Fas 단백질의 발현 증가 및 anti-apoptotic Bcl-2 발현의 감소와 mitochondrial membrane potential의 소실이 동반되었다. 아울러 사간탕 추출물이 처리된 AGS 위암세포에서 extrinsic 및 intrinsic apoptosis 경로 활성의 개시에 중요한 caspase-8 및 -9 뿐만 아니라 effector caspase인 caspase-3의 활성도 증가하였으며, 활성화된 caspase-3의 기질 단백질인 PARP의 단편화도 관찰되었다. 그러나 pan-caspase inhibitor의 선처리에 의한 caspase 활성을 차단하였을 경우, 사간탕 추출물 처리에 의한 염색질 응축 및 DNA 단편화 현상이 관찰되지 않았으며, apoptosis 유발 및 증식억제 효과도 유의적으로 억제되었다. 따라서 사간탕 추출물 처리에 의한 AGS 위암세포의 apoptosis 유발은 extrinsic 및 intrinsic apoptosis 경로가 동시 활성을 통한 caspase 의존적인 과정을 통하여 이루어지고 있음을 알 수 있었으며, 그 과정은 아마도 pro-apoptotic Bid의 truncation이 관여할 것으로 추정된다. 이상의 결과는 향후 in vivo 모델을 이용한 사간탕 추출물의 항암활성 조사 및 사간탕 추출물 내 주요 생리활성 물질의 탐색 등을 위한 유용한 자료로 사용될 것이다.

상엽은 뽕나무 잎을 건조한 약재로서 항염증, 항당뇨, 미백, 항산화, 항박테리아, 항알러지 및 면역조절 등과 같은 여러 가지 약리작용을 하는 것으로 알려져 있으나 항비만 효능에 대한 연구는 부족한 실정이다. 본 연구에서는 상엽 에탄올 추출물(ethanol extracts of Mori Folium, EEMF)이 유발하는 항비만 효능을 확인하기 위하여 3T3-L1 지방전구세포가 지방세포로 분화되는 과정에서 EEMF가 어떠한 영향을 미치는 지를 조사하였다. 3T3-L1 지방전구세포의 분화유도 시 EEMF를 처리하였을 경우 지방세포의 특징인 지방방울의 수 및 지방함량이 농도의 존적으로 감소하였으며, triglyceride의 생성도 억제되는 것으로 나타났다. 또한 EEMF는 pro-adipogenic transcription factors인 SREBP-1c, $PPAR{\gamma}$, $C/EBP{\alpha}$ 및 $C/EBP{\beta}$ 의 발현억제와 함께 adipocyte-specific genes인 aP2 및 Leptin의 발현억제도 유발하는 것으로 조사되었다. 특히 EEMF는 AMPK 및 ACC의 인산화를 억제하는 것으로 나타났지만 AMPK 억제제인 compound C를 이용하여 AMPK의 활성을 억제하였을 경우 EEMF에 의하여 유발되는 pro-adipogenic transcription factors 및 adipocyte-specific genes의 억제현상이 회복되었다. 이상의 결과에서 EEMF가 유발하는 adipogenesis의 억제는 AMPK signaling pathway의 활성화를 통하여 유발된다는 것을 알 수 있었으며, 추가적인 연구를 통하여 상엽에 함유되어 있는 유효성분에 대한 분석이 필요할 것으로 생각된다.

STZ를 이용한 당뇨유발은 독성물질에 의한 췌장 세포의 파괴를 인위적으로 유도시킴으로써 일정하게 고혈당을 유지 시켜주는 방법이다. 장기적인 고혈당은 인슐린의 민감도를 감소시키고 췌장기능을 저하시키며 잠재적으로는 당뇨병의 악화 및 심혈관 합병증을 유도한다(28,29). 이에 본 연구에서는 STZ로 당뇨를 유발한 흰쥐에 AD복합물을 단회 및 반복 투여한 후 혈당변화에 미치는 영향을 조사한 결과 AD복합물의 단회 투여에서 시간별($0{\sim}4$시간)로 혈당변화가 관찰되었다. DC군의 공복혈당은 $437.3{\pm}28mg/dL$에서 3시간 후의 혈당이 $443.3{\pm}28mg/dL$로 거의 변화가 없었던 반면 AD1군은 $414.0{\pm}19mg/dL$에서 $358{\pm}35mg/dL$로 AD2군은 $401.0{\pm}28mg/dL$에서 $351{\pm}16mg/dL$로 혈당이 낮춰졌다. 또한 경구당부하 실험에서는 DC군에 비해 AD복합물 투여군이 포도당 투여 1시간 후의 혈당상승을 억제하고 빠른 속도로 원래의 혈당으로 회복시키는 역할을 하는 것으로 확인되었다. 이러한 결과들이 AD복합물의 장기투여에서도 나타나는지 확인하기 위하여 STZ로 당뇨를 유발시킨 흰쥐에 4주 동안 AD복합물을 투여하고 1주마다 혈당변화를 측정한 결과 DC군은 4주 동안 투여 전(0주) 혈당인 $385{\pm}9mg/dL$를 마지막 주인 4주까지 $365{\pm}6mg/dL$로 꾸준히 비슷하게 유지한 반면, AD1군은 투여 전 혈당인 $349{\pm}9mg/dL$에서 $260{\pm}8mg/dL$로 감소한 것으로 나타났고 AD2군은 투여 전 혈당인 $430{\pm}10mg/dL$에서 $267{\pm}38mg/dL$로 공복 시 혈당저하 효능을 갖는 것으로 나타났다. 또한 AD복합물의 투여는 당뇨로 인한 체중감소를 억제하는 효과가 나타났다. 이러한 결과는 체내의 당대사를 촉진시켜 공복혈당감소와 체중감소억제 효과가 나타난 것으로 사료된다.
