Background & Object : It is well known that functional dyspepsia is one of the most common diseases. While many dyspepsia patients have been helped with oriental medical therapy, there has not been a study based on the concepts of oriental medicine. The aim of this study was to perform a fundamental epidemiological survey and to analyse the symptom pattern of functional dyspepsia. Methods : 86 patients(27 males, 59 females) diagnosed with functional dyspepsia in Kyunghee Oriental Medical Center from May to December 2002 were involved in this investigation. The disease characteristics of functional dyspepsia(based on Rome criteria II) and the Qui Xue Shui diagnostic procedure were investigated by questionnaire and physical examination. The total score and composition ratio of each comprehensive diagnosis were calculated from the symptom score described in the questionnaire. Results : The total score from the Qui Xue Shui diagnostic procedure was found to be influenced by the number of functional dyspepsia symptoms(p=0.026) and the patient's own cognition of their current dyspeptic situation(p=0.006), in addition to digestive ability and general congnition(p=0.006), and was not associated with sex, duration of dyspeptic symptoms in one year, or the total illness period, In the composition ratio of the Qui Xue Shui diagnostic procedure, only Qui-yu(p=0.048) diagnosis was accurate regarding the number of symptoms in one year, total illness period, or the patients' own congnition of their current dyspeptic situation, But the value of the composition ratio among the total factors involved was most similar to that of sex. Conclusions : Thus, it is shown here that the total score of using the Qui Xue Shui diagnostic procedure is mainly dependent on dyspeptic symptoms and the patinets' own cognition of their current dyspeptic situation, and that regular symptom patterns in the Qui Xue Shui diagnostic procedure exist in dyspeptic patients.
Among 12 kinds of ginsenosides in ginseng saponin, ginsenoside-Rb$_1$was contained the most abundantly. But ginsenoside-Rd which is similar to ginsenoside-Rb$_1$in structure, was known to be superior to ginsenoside-Rb$_1$pharmaceutically. In order to convert ginsenoside-Rb$_1$into ginsenoside-Rd by microbial enzyme treatment, a Rhizopus sp. was selected among various strais of molds found in rotten ginseng roots. Enzyme was prepared from the extract of wheat bran koji culture by ammonium sulfate precipitation (1.0 sat'd) and succeeding ammonium sulfate fractionation method (0.6-0.9 sat'd). For the purpose of use as substrate, saponins were purified by the several purification steps from alcohol extract of red ginseng roots. We obtained the total saponin which was composed of 36.5% of ginsenoside Rb$_1$, 12.2% of ginsenoside-Rd and other ginsenosides. For increase of ginsenoside-Rb$_1$ component ratio, we also obtained further purified ginsenoside-Rb group saponin containing 54.5% of ginsenoside-Rb$_1$, 1.1% of ginsenoside- Rd and other ginsenosides from purified the total saponin. In the enzymatic reaction system including the total saponin or the ginsenoside-Rb group saponin, we confirmed the specific conversion of ginsenoside-Rb$_1$to ginsenoside-Rd proportionally and no change of any other ginsenoside patterns by thin layer chromatography and high performance liquid chromatography.

Obesity is a major obstacle for human health, which induces various diseases such as cardiac injury and type 2 diabetes. Ginsenosides, active components of ginseng extract, exert various physiological effects. However, There are still no evidence for their anti obesity effects. In this study, we investigated the effects of ginsenoside Rd on adipocyte differentiation in 3T3-L1 cells. Our data show that ginsenoside Rd (80 uM) was effective in adipocyte differentiation inhibition. These inhibitory effects of ginsenosides on adipocyte differentiation were accompanied by PPAR gamma inhibition in rosiglitazone-treated cells. We also tested whether AMP-activated protein kinase (AMPK) activation was involved in the effects of these ginsenosides. AMPK is a master target for obesity, ginsenoside Rd significantly activated AMPK. Taken together, these results suggest that the anti obesity effects of ginsenoside Rd involve the AMPK signaling pathway and PPAR-gamma inhibition.
Background & Object : The aim of this study was to investigate the usefulness of electrogastrography on differential diagnosis of deficiency or excess Condition in patients with functional dyspepsia Methods : Selected symptoms for diagnosis of deficiency and excess in functional dyspepsia have been reviewed in some literatures, notably within Oriental medicine, Donguibogam and Gogeumdoseojipseong-uibujeolrok. This is what was investigated in this study. 93 patients (male 32, female 61) were divided into three groups; Non-pain group, Pre-treatment pain group (chief complain was abdominal pain at the first medical examination), and Mid-treatment pain group(they had no pain at the time of first medical examination, but showed abdominal pain within two weeks). 10 healthy people participated as normal controls. Gastric motility were recorded and analyzed using electrogastrography during fasting and postprandial period. In assessment, effectiveness was divided into validity, sensitivity and specificity. Results : Epigastric pain reflected the tendency for excess condition in comprehensive diagnosis, which was linked with postprandial arrhythmia in electrogastrography(p=0.001). Postprandial arrhythmia detected abdominal pain with a validity of 78.6%, a sensitivity of 79.2%, and a specificity of 78%(p<0.001). Conclusions : Results 1Tom Postprandial arrhythmia in electrogastrography support that the index of excess condition in the comprehensive diagnosis of symptoms is useful for patients with functional dyspepsia.
Ginsenosides have been regarded as the principal components responsible for the pharmacological and biological activities of ginseng. Absorption of major ginsenosides from the gastrointestinal tract is extremely low, when ginseng is orally administered. In order to improve absorption and its bioavailability, conversion of major ginsenosides into more active minor ginsenoside is very much required. Here, we isolated lactic acid bacterium (Lactobacillus brevis LH8) having ${\beta}-glucosidase$ activity from Kimchi. Bioconversion ginsenoside Rd by this bacterium in different temperatures was investigated. The maximum activities of crude enzymes precipitated by ethanol were shown in $30^{\circ}C$ and then gradually decreased. In order to compare the effect of pH, the crude enzymes of L. brevis LH8 were mixed in 20mM sodium phosphate buffer (pH 3.5 to pH 8.0) and reacted ginsenoside Rd. Ginsenoside Rd was almost hydrolyzed between pH 6.0 and pH 12.0, but not hydrolyzed under pH 5.0 and above pH 13.0. Ginsenoside Rd was hydrolyzed after 48 h incubation, whereas ginsenoside F2 appeared from 48 h to 72 h, and ginsenoside Rd was almost converted into compound K after 72 h.
Reactive distillation (RD) is a combination process where both separation and reaction are considered simultaneously in a single vessel. This kind of combination to enhance the overall performance is not a new attempt in the chemical engineering areas. The recovery of ammonia in the classic Solvay process for soda ash of the 1860s may be cited as probably the first commercial application of RD. The RD system has been used for a long time as a useful process and recently the importance of the RD is enlarged more and more. In addition to that, the application fields of RD are diversely diverged. To make the most of the characteristic of RD system, we must decide the best operating condition under which the process shows the most effective productivity and should decide the best control algorithm which satisfies an optimal operating condition. Phosgene which is a highly reactive chemical is used for the production of isocyanates and polycarbonates. Because it has high reactivity and toxicity, its utilization is increasingly burdened by growing safety measures to be adopted during its production. Dimethyl Carbonate (DMC) was proposed as a substitute of phosgene because it is non-toxic and environmentally benign chemical. In this study, RD is used for DMC production process and the transesterification is performed inside of column to produce DMC. In transesterification, the methanol and ethylene carbonate (EC) are used as the reactants. This process use homogeneous catalyst and the azeotrope exists between the reactant and product. Owing to azeotrope, we should use two distillation columns. For this DMC production process, we can suggest two configurations. One is EC excess process and the other is methanol excess process. From the comparison of steady state simulation results where the Naphtali-Sandholm algorithm is used, it showed the better performance to use the methanol excess process configuration than EC excess process. Then, the dynamic simulation was performed to be based on the steady state simulation results and the optimal control system was designed. In addition to that, the optimal operating condition was suggested from previous results.
The effect of aqua-acupuncture of total saponin on the recovery of liver function in -intoxicated rats was exemined. Rats were divided into normal, control and three experimental groups (As-I group : aqua-acupuncture of saline to Gansu locus and Aa-III group : aqua-a-cupuncture of total saponin to blank locus at the thigh). Changes of some serum biochemical parameters (ALT, AST and ALP, total protein and albumin, and albumin/globulin (A/G) ratio) were determined. Serum ALT activities were increased by $CCI_{4}$T and decreased in all aqua-acupuncture groups compared with the control group. Aa-I group showed significant decrease of ALT activities on the 2nd (P<0.05) and 3rd (P<0.05) day, respectively. Aa-II group showed significant decrease on the 3rd day (P<0.05) day. Serum AST activities were increased by $CCI_{4}$T and decreased in all apua-acupuncture groups compared with the control group. Aa-I group showed significant decrease on the 1st (P<0.05), 2nd (P<0.001) and 3rd (P<0.001) day, respectively. Aa-II group showed significant decrease on the 3rd (P<0.001) day. Aa-III group showed significant decrese on the 1st (P<0.05) and 3rd (P<0.001) day, respectrvely. Serum ALP activities were increased by $CCI_{4}$T and decreased in all aqua-a-cupuncture groups compared with the control group. Aa-I group showed significant decrease on the 3rd (P<0.01) day. Total protein, albumin and A/G ratio were decreased by $CCI_{4}$T and increased in all aqua-acupuncture groups compared with control group. Aa-I group showed significant increase only on the 3rd day in albumin (P<0.01). It was thought that the aqua-acupuncture of total saponin to Gansu locus was effective on the recovery of liver function in $CCI_{4}$T-intoxicated rats.

Immunoglobulin G4 (IgG4)-related dacryoadenitis and sialoadenitis (IgG4-DS) are part of a multiorgan fibroinflammatory condition of unknown etiology termed IgG4-related disease (IgG4-RD), which has been recognized as a single diagnostic entity for less than 15 years. Histopathologic examination is critical for diagnosis of IgG4-RD. CD4+ T and B cells, including IgG4-expressing plasma cells, constitute the major inflammatory cell populations in IgG4-RD and are thought to cause organ damage and tissue fibrosis. Patients with IgG4-RD who have active, untreated disease exhibit significant increase of IgG4-secreting plasmablasts in the blood. Considerable insight into the immunologic mechanisms of IgG4-RD has been achieved in the last decade using novel molecular biology approaches, including next-generation and single-cell RNA sequencing. Exploring the interactions between CD4+ T cells and B lineage cells is critical for understanding the pathophysiology of IgG4-RD. Establishment of pathogenic T cell clones and identification of antigens specific to these clones constitutes the first steps in determining the pathogenesis of the disease. Herein, the clinical features and mechanistic insights regarding pathogenesis of IgG4-RD were reviewed.
Objectives : While the proportion of clinical trials is increasing in oriental medical research, no studies in recruitment strategies exist. This study was conducted to investigate which recruitment strategy was efficient to increase the number of potential subject and to reduce cost. Methods : Data from 179 callers in a single-center between June 22 and August 12, 2010 were analyzed. Results : We found that daily newspaper and free newspaper advertisement collected maximal participants. Advertisements in the hospital and on the Internet were considered as the most cost-effective methods. Conclusions : Intensive multiple overlapping recruitment strategies might be effective in success of participant registration in a clinical trial.
Purpose: To evaluate the efficacy of synbiotic formula with partial whey hydrolysate and high magnesium content in infants presenting with functional constipation. Methods: Sixty-five infants with functional constipation were included. Forty infants were treated during one month with parental reassurance and the intervention formula and were compared to a control group of 25 infants treated with parental reassurance only. Parents completed a quality of life (QoL) questionnaire at baseline and during the last week of the study. Results: At inclusion, stool characteristics and QoL were similar in both groups. The control group was slightly older than the intervention group ($7.5{\pm}3.9$ vs. $6.2{\pm}3.6$ weeks). At onset, stool composition was "hard and tight" (Bristol stool scale 1 and 2) in all infants. After one month, stool composition remained unchanged in the control group except in two infants that developed "creamy" stools (Bristol stool scale type 3 and 4). In the intervention group, stools remained "hard and tight" in 27.5%, and became "creamy" in 47.5%, "loose" (Bristol stool scale type 5) in 22.5% and "watery" (Bristol stool type 6 and 7) in 2.5%. The benefit of the intervention formula was estimated to be "very important" in 70%. The median scores for QoL improved significantly in the intervention group for all parameters and for one in the control group. Conclusion: The intervention formula significantly improved functional constipation resulting in a better QoL of the parents and infants.
