Objective : This study was designed to investigate anti-diabetic effects of fermented soy bean extract with herbal medicines (Godjang) in diabetic rat models induced by streptozotocin (STZ) injection. Method : Changes in body weight, drinking water, and food intake were observed for 4 weeks before and after induction of diabetes mellitus in rats. The anti-diabetic capacity of Godjang was analyzed by fasting blood glucose (FBG) every week. Also, after 4 weeks of administration, the oral glucose tolerance test (OGTT) was performed, and then blood levels of insulin were checked. And serum levels of total cholesterol and triglycerides were determined. Histomorphological changes of liver, kidney and pancreatic tissues were also observed in STZ-induced diabetic rats and Godjang administered rats. Result : In Godjang administered group, body weight and water intake were more lower than that of STZ-induced diabetic rats. FBG was decreased in the Godjang administered group than STZ-induced diabetic group. According to OGTT, blood glucose levels at 30 minutes and 60 minutes significantly decreased in Godjang administered group than in STZ-induced diabetic control group. Administration of Godjang extract for 4W significantly decreased levels of serum glucose, total cholesterol (TC), triglycerides (TG) in diabetic rats. In histomorphological analysis of kidney, liver, Godjang administrated groups showed the inhibition of pathological damage. Conclusion : These results suggest that Godjang extract has an anti-diabetic action through decrease in serum glucose, TC, TG levels and recovery of the morphological changes in kidney and liver in STZ-induced diabetic rats.

Objectives : Liver disease is an inflammatory reaction caused by oxidative stress, viral, alcohol, and drug properties. Inflammatory reaction causes hepatitis and chronic hepatitis is persistent, it progresses to liver fibrogenesis and liver cancer. The aim of this study was to confirm the hepatoprotective effect of Tongyuhwalhyeol-tang(Tongqiaohuoxue Decoction) (TH) and Gamtongyuhawlhyeol-tang(GTH) in TAA-induced liver injury animal model. Methods : The antioxidant activities were evaluated through in vitro experiments, such as 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and 2, 2'-azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS) radical scavenging assays, total polyphenol and total flavonoid content measurement. To confirm the liver protective effect, induced by Thioacetamide (TAA) for 3 days injection at 200 mg/kg rats. TH and GTH were treated 3 days at 200 mg/kg/day. The changes of reactive oxygen species (ROS), peroxynitrite ($ONOO^-$), alanine aminotransferanse (ALT) and aspartate aminotransferase (AST) in serum were analyzed after experiment. Also, expression of anti-inflammation, anti-oxidant related proteins were investigated by western blot analysis. Results : TH was inhibited the antioxidant activities. In the TAA-induced rat, TH decreased ROS, $ONOO^-$, ALT, AST level in serum. Inflammation related protein expressions increased in TAA-induced rat compared to normal rat. However, TH group inhibited the down expression of these proteins. Also, anti-oxidant related protein expressions increased in TH group compared TAA-induced rat. Conclusion : Therefor, these results suggested that TH provided hepatoprotective effects on the hepatic injury leading to the reduction of inflammatory response. In addition, the effect of TH was superior to that of GTH.

Objectives : Osteoporosis is a systemic skeletal disorder characterized by reduced bone mineral density and increased risk of fractures. Bisphosphonates and selective estrogen receptors, which are bone resorption inhibitors that are currently widely used as osteoporosis treatments, show serious side effects when administered for a long time. Research on bone resorption inhibitors that complement the problems of existing treatments is needed. The purpose of this study was to investigate the effect of inhibiting osteoclast differentiation and activity on the tuberous root of Ampelopsis japonica (Thunb.) Makino (AM). Methods : After extracting AM using distilled water and ethanol, the inhibitory effects of the two solvents on osteoclast differentiation were compared using the RANKL-induced in vitro experimental model and the TRAP assay kit. The impact of AM on bone resorption was investigated through the pit formation assay, and its effect on F-actin formation was assessed through fluorescent staining. Additionally, protein and mRNA expression levels of osteoclast differentiation markers (NFATc1, c-Fos, TRAP and ATP6v0d2) and resorption markers (MMP-9, CTK, and CA2) were analyzed via western blot and RT-PCR. Results : AM treatment significantly decreased the number of TRAP-positive cells and pit formation area. Furthermore, AM suppressed both the protein and mRNA expression of NFATc1 and c-Fos, key transcription factors involved in osteoclast differentiation and it downregulated the expression of osteoclast-associated genes such as TRAP, CTK, MMP-9, CA2, and ATP6v0d2. Conclusions : These results suggest that AM can inhibit bone resorption and osteoclast differentiation, indicating its potential for use in the treatment and prevention of osteoporosis.

Objectives : Oxidative stress is a important cause of liver disease, and regulation of oxidative stress is essential to maintain the normal metabolic function of the liver. Until a recent date, there has been no studies on the hepatoprotective effect of Ikwiseungyang-tang (IWSYT). Therefore, this study aims to demonstrate the hepatoprotective effect of IWSYT and its related molecular mechanisms on arachidonic acid (AA) + iron induced oxidative stress model in HepG2 cells. Methods : To determine the cytoprotective effect of IWSYT against AA + iron-induced oxidative stress, cell viability, apoptosis-related proteins, intracellular reactive oxygen species (ROS), GSH, and mitochondrial membrane potential (MMP) were measured. Nuclear factor erythroid 2-related factor 2 (Nrf2) activation was analyzed by immunoblot analysis. In addition, Nrf2 transcription activation through ARE binding was measured by reporter gene assays, and the expression of the Nrf2 target antioxidant genes were confirmed by immunoblot analysis. Results : IWSYT increased cell viability from cell death induced by AA + Iron, and inhibited apoptosis by regulating apoptosis-related proteins. Furthermore, IWSYT protected cells by inhibiting intracellular ROS production, GSH depletion, and MMP degradation. Nrf2 activation was increased by IWSYT, and Nrf2 target genes were activated by IWSYT too. Conclusions : These results suggest that IWSYT can protect hepatocytes from oxidative stress through Nrf2 activation and can be potentially applied in the prevention and treatment of liver damage.

Backgrounds : In 2017, National Health Insurance implemented the pilot coverage program for Chuna manual therapy(CMT). 65 Korean Medicine(KM) hospitals and clinics were selected in the program to monitor the effectiveness and patients' satisfaction of insured CMT. Objectives : This study aimed to evaluate patients' satisfaction of CMT in the pilot coverage program of National Health Insurance. Methods : Survey participants were recruited among the patients who used CMT at the designated organizations. On-line questionnaire link was sent to the smart phones of patients who agreed to participate in the survey and provide personal contact information. The questionnaire consisted of the basic charactersitics of respondents, imformation on using CMT satisfaction with CMT and willingness to recommend CMT to others. The answers that were automatically coded and saved were statistically analyzed. Results : Of 386 participants who completed the questionnaire, 92.8% satisfied or strongly satisfied with the CMT. Most frequent reason of satisfaction was 'Good effectiveness', and there was no difference in satisfaction between patients of hospital and those of clinics. Patients with the highest and the lowest level of pain satisfied more than those with other pain levels(p=0.003), but the level of copayment and reasons of CMT use did not affect the satisfaction results(p=0.405). The proportions of respondents who had willingness to recommend CMT to others and to revisit for CMT use were 97.8% and 98.8%, respectively. Conclusions : Most patients were satisfied with CMT in the pilot coverage program, and it can provide the rationale for expanding the insurance coverage of CMT to all KM hospitals and clinics.

Objectives This review aimed to investigate studies of Chuna manual therapy (CMT) for low back pain and the evidence of their effects in order to suggest a better research method in the future. Methods We investigated studies on CMT for low back pain by searching Korean web databases from 2020 to 2021. As a result, 72 research papers were analyzed according to their published year, the titles of journals, the types of studies, the techniques of Chuna, and the instruments used for assessment. Results The results were as follows: 1. There were three papers published initially in 2000. this number showed a steady increase, and a total of 72 papers were published that year. 2. Studies on CMT were mainly published in the Journal of Korea Chuna Manual Medicine for Spine and Nerves. 3. When categorized according to the methods of studies, a simple case report was used more often than the sum of randomized controlled trials (RCTs) and non-RCTs. 4. The most frequently adopted technique of Chuna in the examined studies was the COX flexion and distraction technique. 5. The Visual Analog Scale and Oswestry Disability Index were used as primary means of assessment. Conclusions Based on the analysis, it was observed that this review provided limited evidence of CMT use in patients with LBP. Therefore, further investigation using well-designed RCTs is required to obtain higher evidence.
