The aim of this study was to evaluate the clinical efficacy and safety of fermented medicinal herbs. A search of the China National Knowledge Infrastructure (CNKI), PubMed databases and Korean Journal of Oriental Medicine in 2000-2011 located 11 randomized controlled trials (RCTs) that investigated the clinical efficacy of fermented medicinal herbs. Domestic RCTs reported clinical efficacy on improvement of immune responses and clinical safety on usage of fermented medicinal herbs in subjects suffering from cerebral hemodynamics. Countries other than Chinareported studies on the cause of esophageal cancer and on local inflammatory reactions. In China, studies were reported on the effectiveness of fermented medicinal herbs on scapulohumeral periarthritis of the stasis type, chronic superficial gastritis, dysuria induced by benign prostatic hyperplasia of deficiency of kidney yang, diabetic nephropathy, essential hypertension, and benign prostate hyperplasia. These results indicate that fermented medicinal herbs have obvious clinical effects in some diseases and no adverse reactions. Therefore, we need to initiate more fermentation research with useful bacteria, fungi, and mushrooms to produce fermented medicinal herbs. Both governments and research authorities should focus on research involving fermentation of medicinal herbs.

Sasa quelpaertensis Nakai (Korean name, Jeju-Joritdae) is one of the most abundant plants on Mt. Halla, Jeju Island, and it has long been used in traditional medicines. Recent studies have reported it as possessing various beneficial functions, including anti-inflammatory, anti-diabetic, anti-hypertension, anti-gastritis, anti-oxidant, and anti-cancer effects. However, the molecular mechanisms of its anti-cancer activity have not been clearly elucidated. In this study, we investigated the anti-cancer effects and mechanism of S. quelpaertensis on human colon cancer HT-29 cells. Cell growth inhibition by S. quelpaertensis was determined by MTT assay. Apoptosis was performed by DNA fragmentation, flow cytometry with propidium iodide staining (PI), and reverse transcription-polymerase chain reaction (RT-PCR) to confirm the anti-apoptotic factors, such as inhibitor of apoptosis (IAP) family members. $NO^{\bullet}$ production was determined by Griess assay. S. quelpaertensis treatment resulted in the time- and dose-dependent inhibition of the cell viability of HT-29 cells by inducing apoptosis, as evidenced by the accumulation of the sub-G1 cell population stained by PI, as well as the ladder-like DNA fragmentation in a dose-dependent manner. S. quelpaertensis-inducing apoptosis was accompanied by the induction of S cell cycle arrests, increasing $NO^{\bullet}$ concentrations, and the down-regulation of IAPs, including X-chromosome-linked IAP (XIAP), cellular IAP-1 (cIAP-1), cIAP-2, and survivin. Taken together, these findings have important implications for future clinical developments of S. quelpaertensis in colon cancer treatment.

Ginseng has been known to be highly effective for health as a traditional medicinal herb. Ginseng berry, or fruit of ginseng, contains ginsenoside, saponin, polyphenol, polyacetylene, alkaloid, etc. as the main compounds as does ginseng. The aim of this study is to evaluate any effect of ginseng berry water extract (GBE) on diabetic-associated molecules, such as enzymes, which are responsible for the glucose entry of the cells and the insulin receptor signaling molecules using HepG2 cells. Therefore, two enzymes, ${\alpha}$-amylase and ${\alpha}$-glucosidase, were selected and assayed for their activities in the presence of GBE in vitro. These two enzymes are responsible for producing glucose from dietary starch. Protein-tyrosine phosphatase 1B (PTP1B) and Akt1 are key proteins in the insulin receptor signaling pathway. These two intracellular signaling molecules were investigated for their expression levels in HepG2 cells after insulin and GBE treatment. GBE, at concentrations up to $1,000{\mu}g/ml$, did not exert any inhibitory effect on ${\alpha}$-amylase and ${\alpha}$-glucosidase. It was observed that the expression level of PTP1B was increased by insulin and the $25{\mu}g/ml$ GBE treatment enhanced the PTP1B level. However, GBE at a concentration of $200{\mu}g/ml$ reduced the expression level of PTP1B. In the case of Akt1, the Akt1 level by insulin was decreased by GBE treatment. These data suggest that the water extracts of ginseng berry have an influence on intracellular signaling by insulin.

Dietary supplements have exhibited myriads of positive health effects on human health conditions and with the advent of new technological advances, including in the fields of proteomics, genomics, and metabolomics, biological and pharmacological activities of dietary supplements are being evaluated for their ameliorative effects in human ailments. Recent interests in understanding and discovering the molecular targets of phytochemical-gene-protein-metabolite dynamics resulted in discovery of a few protein signature candidates that could potentially be used to assess the effects of dietary supplements on human health. Persimmon (Diospyros kaki) is a folk medicine, commonly used as dietary supplement in China, Japan, and South Korea, owing to its different beneficial health effects including anti-diabetic implications. However, neither mechanism of action nor molecular biomarkers have been discovered that could either validate or be used to evaluate effects of persimmon on human health. In present study, Mass Spectrometry (MS)-based proteomic studies were accomplished to discover proteomic molecular signatures that could be used to understand therapeutic potentials of persimmon leaf extract (PLE) in diabetes amelioration. Saliva, serum, and urine samples were analyzed and we propose that salivary proteins can be used for evaluating treatment effectiveness and in improving patient compliance. The present discovery proteomics study demonstrates that salivary proteomic profile changes were found as a result of PLE treatment in prediabetic subjects that could specifically be used as potential protein signature candidates.

Microalbuminuria is most frequently caused by kidney damage from diabetes. Moreover, many other conditions can lead to kidney damage, such as high blood pressure, heart failure, cirrhosis, or systemic lupus erythematosus (SLE). The measurement of the microalbumin in urine may be useful for the early diagnosis or as a predictor of nephropathy in diabetes. The most common method for getting a quantitative measurement of urinary protein relies on a 24-hour urine collection. The result of this method is accurate. But 24hr urine collection is difficult to obtain and variations in volume are frequent. Also the patients complain about urine collection. We tried to measure reference values for microalbumin using fasting urine and compare them with the albumin/creatinine ratio using 24hr urine. The concentrations of microalbumin in fasting urine and 24hr urine were $7.1{\pm}3.8mg/L$, $5.7{\pm}2.9mg/L$ (r=0.61, p=0.27), respectively. The albumin/creatinine ratios using fasting urine and 24hr urine were $8.7{\pm}4.2{\mu}g/mg$, $8.7{\pm}4.0{\mu}g/mg$ (r=0.76, p=0.88), respectively. This study indicated that the measurement of microalbumin in fasting urine was an easy and simple method for early diagnosis or to predict nephropathy in diabetes. Thus, setting up the reference value using fasting urine may be useful in the screening test for the diabetic nephropathy patients instead of using the 24hr albumin excretion rate (AER).

Objectives : This study was aimed at investigating the medical service utilization pattern of patients who use public medical aid compared to those who have health insurance. Methods : We selected every patient between the age of 18 and 69 who used public medical aid from January 1, 1999, to December 31, 2001, in Gwangju metropolitan city, South Korea. For comparison, a list of patients with health insurance was gathered for same period. Then the medical records of those who had been hospitalized for acute appendicitis were selected among both groups. Of those records, we compared the number of cases of ruptured appendicitis to cases of whole acute appendicitis in both groups. Regarding coding for ruptured appendicitis, International Classification of Diseases - 10 (ICD-10) was used. Multiple logistic regression was used as a statistical tool to determine the effectiveness of risk factors. Results : Even after adjusting for risk factors, such as age and sex, the proportion of perforation of acute appendicitis among public medical aid patients was found to be significantly higher than among insured patients. Conclusions : This comparative study on ruptured appendicitis among public medical aid patients and insured patients, indicates that the proportion of perforation of acute appendicitis could be an index showing that these types of patients utilize medical services differently than insured patients. We know that when abdominal pain is not properly treated at the outset, it easily develops into ruptured appendicitis complicated with peritonitis. Considering this data analysis, we guess the public medical aid system to have significant problem with medical accessibility. So additional and systematic research on the pattern of utilization of medical services of public medical aid patients is needed.

A new vacuum assisted auto-lancing technique is proposed to minimize pain. Specially designed lancing device was introduced, which applied -100mmHg right after skin puncture on the forearm. Sampled blood volumes were measured in 58 normal females. Mean volume of 464 samples was approximately 2.6$\muL$ and the frequency of more than 0.5$\muL$ was 86%. Thus the success rate of blood sugar test should also be the same when using modern glucose meters capable of testing with only 0.3~0.5$\muL$ of capillary blood. When pain scores were quantitatively evaluated by the visual pain measure, only 23% pain of the traditional finger sampling was experienced, demonstrating that capillary blood sampling was performed on the forearm with almost no pain. The present technique reduced pain to a great degree, though resampling might be unavoidable due to 14% of test failure rate estimated for modern glucose meters. However, minimized pain makes the present technique of great convenience for diabetic patients who need blood sampling a few times a day.

It has increased that peripheral disturbance(blood flow, nerve, Raynaud's phenomenon) and finger rheumatoid arthritis which is caused by the diabetic complications. To improve these pain issues, we proposed new method for the Finger Disease Therapy(FDT). In this paper, we manufactured solenoid cylindrical coil which was only for the FDT using a variable micro-electromagnetic. Also, we designed the Finger Disease Therapy System(FDTS) which could select three stimulation modes(N_pulse, S_pulse, N/S_pulse) and frequency(0.25hz, 0.5hz, 1hz). We used a Teslameter to measure magnetic flux inner solenoid, and measured magnetic flux as distance(0 ~ 3cm) inner solenoid with stimulation modes and frequency. In the results, magnetic flux was the highest in center of solenoid(0cm) for all stimulation modes. Also, the highest magnetic flux was measured as N_pulse(294.3mT), S_pulse(293.8mT) in 1Hz and N/S_pulse (275.4mT) in 0.25Hz, respectively. Therefore, we developed the FDTS using various pattern and intensity for finger diseases therapy, and checked therapy clinic application possibility of the FDTS as measuring magnetic flux inner solenoid.

GM-CSF is a multipotent growth factor, which also plays an important role during the process of wound healing. rrhGM-CSF was specifically produced from rice cell culture in our laboratory (Hanson Biotech Co., Ltd, Daejeon). The rrhGMCSF contains more oligosaccharide side chains than any other types of GM-CSF. This work was taken to evaluate the influence on wound healing of rrhGM-CSF in male golden hamsters. Full thickness skin defects of 9 mm in diameter were made in the back of hamsters, and 100 ${\mu}L$ ointment containing rrhGM-CSF 50 ${\mu}g/mL$ was applied. Control groups were given ointment without rrhGM-CSF. The wound sizes were relatively reduced and skin was well regenerated in the experimental group compared with the control group. Structurally, reepithelialization and architecture of the skin following injury were well accomplished in the experimental group. And also, positive reaction of PCNA of the skin following injury was more prominent in rrhGM-CSF containing ointment treatment group. Since this type of GM-CSF has highly glycosylated side chains, the effectiveness might be retain longer and stable, regarding acceleration of wound healing in the animal model. The present study has important implications for further development of the therapeutic manipulation of wound healing using rrhGM-CSF.
