Objectives : The aim of this study was to evaluate the therapeutic effect of acupuncture and herbal medicine in patients who had hvpoactivity of the gastric vagus nerve and pyloric valve disturbance simultaneously with function dyspepsia by bowel sounds analysis. Methods : Bowel sounds of 10 patients (male 1, female 9) were recorded and their % of bowel sound (%BS) and ratio of dominant frequency (DF) were analyzed before and after treatment. Hypoactivity of the gastric vagus nerve was considered if % BS was <6%. and pyloric valve disturbance was accepted if DF ratio (e.g.. postprandial DF/fasting DF) was <1. Electroacupuncture at Zusanli (ST36, 3Hz, 30 minutes) and manual acupuncture at other meridian points were applied daily for 2 weeks. Herbal medicine, Pyengwi-san. was administered to all patients (100cc, 3 times/day). Results : DF ratio significantly increased from $0.93\pm0.06$ to $1.06\pm0.04$ after treatment for 2 weeks (p=0.005). 9 of 10 patients were improved to DF ratio>1. %BS also increased from $2.97\pm1.17%$ to $4.49\pm4.27%$. not significantly. 3 patients showed a remarkable elevation, and their %BS reached >6% of normal value. Conclusions : Combined effect of electroacupuncture at Zusanli (ST36), manual acupuncture. and Pyengwi-san was shown effective in the improvement of pyloric valve disturbance more than hypoactivity of gastric vagus nerve on patients with functional dyspepsia.

The purpose of this study was to investigate the hypoglycemic effect of Saururus chinensis Baill in vitro and in vivo. Methanol extract of S. chinensis Baill inhibited yeast ${\alpha}$-glucosidase activity by 49.8%, which was twice as strong as that of acarbose at a concentration of 0.5 mg/mL in vitro. The effect of S. chinensis Baill methanol extract on the postprandial increase in blood glucose levels was studied in streptozotocin-induced diabetic rats using a carbohydrate load test. Oral administration of S. chinensis Baill extract (500 mg/kg) significantly decreased incremental blood glucose levels at 60 and 90 min (p<0.05) after oral ingestion of starch (1 g/kg). The area under the glucose response curve of the S. chinensis Baill group was significantly decreased compared to that of the control group (p<0.05). The effect of prolonged feeding of S. chinensis Baill was studied in an animal model of type 2 diabetes. Three-week-old db/db mice were fed an AIN-93G diet or a diet containing 0.5% S. chinensis Baill extract for 7 weeks after 1 week of adaptation. Plasma glucose, insulin, and blood glycated hemoglobin levels of the mice fed S. chinensis Baill extract were significantly lower than those of the control group (p<0.05). Therefore, we conclude that S. chinensis Baill is effective in controlling hyperglycemia in animal models of diabetes mellitus.

Purpose: The aim of study was to determine the effects of carbohydrate, fat, protein, and fiber contents on glycemic responses in a single food item or meal. Methods: Glycemic responses were measured in 30 healthy young adults (17 males and 13 females) with various test foods, including rice, egg whites, bean sprouts, olive oil, noodles, prune, broccoli, Korean dishes, Western dishes, and salad dishes, etc. Test foods were designed to contain various carbohydrate, fat, protein, and fiber contents in single or mixed foods or dishes. After 12 hours of fasting, participants consumed test foods, and the glycemic response was measured for a subsequent 120 min (0, 15, 30, 60, 90, and 120 min). Three hundred and fifty three glycemic responses from 62 foods were collected. The incremental area under the curve (AUC) was calculated for each test food for each subject to examine glycemic responses. Statistical analysis was conducted to identify which macronutrient (carbohydrate, fat, protein and fiber) affected the AUC using a mixed model. Results: Carbohydrates (${\beta}=37.18$, p < 0.0001) significantly increased while fat (${\beta}=-32.70$, p = 0.0054) and fiber (${\beta}=-32.01$, p = 0.0486) significantly reduced the glycemic response. Conclusion: It can be concluded that the glycemic response of a meal can be modified depending on the fat and fiber contents of ingredient foods, even though carbohydrate content is maintained.

Functional dyspepsia is one of the most common bowel disorders as prevalent of 7.7% Korean population. The cardinal manifestations include bothersome postprandial fullness, early satiation, epigastric burning or pain. These features are chronic and should be presented recurrently with no other compatible organic disease to explain the symptoms. Even though it is not life-shortening, functional dyspepsia usually make the health-related quality of life worse especially if other functional bowel disorder coexist. The coexistence of functional bowel disorders is called as 'overlap syndrome'. Anxiety, somatization and insomnia is more prevalent in overlap syndrome compared with sole functional bowel disorder. Therefore, it is worthwhile that physician interviews and elucidates whether the dyspeptic patient had other kinds of functional bowel disorders, and manages the underlying psychotic pathology. Placebo effect is large in functional dyspepsia, and there is only four kinds of prokinetics that is proven to be superior to placebo. Adverse events relating prolonged administration of prokinetics sometimes fatal or irreversible, physician willing to describe prokinetics should be familiar to the possible adverse effects and the relating risk factors. Pathologic acid reflux is not uncommon in functional dyspepsia, and acid-suppressant is equivalent to the prokientics in most of dyspeptic patients.

Various records on health, food and treatment are written in ancient documents of Korea such as old recipe books, Korean medical books and history books, through these records, the principle of Sikchi can be discovered. Sikchi includes the meaning of medicine and food work on the same principle, and it is not only as traditional knowledge but also affecting modern food culture. Based on this principle of Sikchi, this study tried to lay a foundation that can be used as a modern health food material through scientific verification of foods recorded in the ancient literature. For this purpose, Omigalsu, a traditional drink made from omija, soybean, and honey, which is related to blood glucose control, which is one of the representative metabolic diseases of modern people, was selected as the subject of this study. In order to compensate for the agglomeration of beverages caused by honey or the rise in postprandial blood glucose, which occurs when the traditional Omigalsu recorded in the ancient literature is reproduced, the raw material that can be substituted for honey was discovered. The health promotion and quality improvement effects of newly prepared Omigalsu using honey substitutive raw material were confirmed through a comparative test with traditional Omigalsu. Based on this study, through scientific research using the principle of Sikchi, we intend to lay a foundation that can be used as various contents in the medical and food fields such as food bio and healthcare in modern society.

Objective: This study was conducted to report the glucose-lowering effect and safety of herbal extracts in patients with type 2 diabetes mellitus. Methods: We investigated 21 patients with type 2 diabetes mellitus who were administered Daeshiho-tang, Bojungikgi-tang, Jowiseunggi-tang, and Hoechunyanggyeok-san at Kyung-Hee University Korean Medical Hospital from 2014 to 2019. The hypoglycemic effect of the herbal extracts was assessed by comparing blood glucose levels, including fasting blood sugar (FBS) and 2-hour postprandial glucose (PP2) levels. For safety assessment, the effects of herbal extracts on liver and kidney function were analyzed by liver function tests, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), and γ-glutamyltransferase (GGT), and kidney function tests, including blood urea nitrogen (BUN) and creatinine (Cr). Patients were stratified according to their glycated hemoglobin (<6.5 or >6.5) levels and the kind of herbal extract used for treatment. Results: After administration of herbal extracts, FBS and PP2 significantly decreased to 20.24 mg/dL and 35.0 mg/dL respectively. Subgroup analysis revealed that, regardless of the glycated hemoglobin level, FBS and PP2 were significantly reduced in both groups. The safety profile showed no significant difference before and after taking herbal extracts. Conclusions: Daeshigo-tang, Bojungikgi-tang, Jowiseunggi-tang, and Hoechunyanggyeok-san may show the further glucose-lowering effects on patients with type 2 diabetes mellitus who have already treated with anti-hyperglycemic agents.

Purpose: Laparoscopic proximal gastrectomy with double-tract reconstruction (LPG-DTR) is a function-preserving procedure performed for treating upper early gastric cancer (EGC). However, few studies have compared the outcomes of LPG-DTR with those of laparoscopic total gastrectomy (LTG). This study aimed at comparing the short-term outcomes of LPG-DTR between LTG and upper EGC. Materials and Methods: For upper-third EGC, a multicenter, prospective, randomized trial was performed to compare those who underwent LPG-DTR with those who underwent LTG. Short-term outcomes, including clinicopathologic results, morbidity, mortality, and postoperative courses, were evaluated using a full analysis set based on the intention-to-treat principle and the per-protocol set. Results: Of the patients, 138 who fulfilled the criteria were randomized to each group. One patient in the LPG-DTR group withdrew consent. Sixty-eight patients underwent LPG-DTR and 69 underwent LTG. The operative time (LPG-DTR=219.4 minutes; LTG=201.8 minutes; P=0.085), estimated blood loss (LPG-DTR=76.0 mL; LTG=66.1 mL; P=0.413), and the morbidity rate (LPG-DTR=23.5%; LTG=17.4%; P=0.373) between the groups were not significantly different. No mortality occurred in either of the study groups. Two weeks post operation, the Visick scores for postprandial symptoms, including reflux symptoms, were not significantly different between the groups (P=0.749). Laboratory findings on postoperative day 5 were not significantly different between the groups. Conclusions: The short-term outcomes of LPG-DTR for upper EGC were comparable to those of LTG.

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.

Objective: This study was conducted to evaluate the hypoglycemic effect and safety of herbal extracts in patients with type 2 diabetes mellitus. Methods: We investigated 19 hospitalized patients with type 2 diabetes mellitus who were administered Banhasasim-tang (BST), Gumiganghwal-tang (GGT), or Pyeongwee-san (PWS) at Kyung Hee University Korean Medical Hospital for at least three days between January 2012 and December 2021. Their clinical characteristics and laboratory tests were reviewed retrospectively. The glucose-lowering effect of the herbal extracts was assessed by comparing blood glucose levels, including fasting blood sugar (FBS), two-hour postprandial glucose (PP2) levels, and glycated hemoglobin levels. To evaluate the safety of the herbal extract, liver function test and kidney function test results were compared, including aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine (Cr). Results: After taking herbal extracts, PP2 and HbA1c levels significantly decreased from 205.82 mg/dL to 171.41 mg/dL and 7.58% to 6.62%, respectively. The safety profile reported no significant difference after taking herbal extracts. Conclusions: BST, GGT, and PWS may have hypoglycemic effects in patients with type 2 diabetes mellitus taking hypoglycemic medication.

Purpose: The prevalence of diabetes mellitus (DM) continues to increase worldwide, and blood glucose control may reduce mortality from diabetic complications and healthcare costs. Mulberry twig (MT) has been used as a herbal medicine in Asia, and its antidiabetic efficacy has recently been reported, but research in this area is still limited. This study examined the antidiabetic effects of water extracts of MT in diabetic animals. Methods: Six weeks old male ICR mice were divided randomly into three groups; normal control (NC, n = 10), DM control (DC, n = 10), and MT (n = 10). Streptozotocin (STZ, 50 mg/kg/day) was injected intraperitoneally into mice in the DC and MT groups for 5 consecutive days. After 10 days of the last STZ injection, the mice in the MT group were administered orally with MT water extracts (5 g/kg body weight) for 16 days. Results: The MT water extracts ameliorated the swelling of the liver in the diabetic mice and reduced the elevated levels of fasting blood and plasma glucose, total cholesterol (T-CHO), low density lipoprotein-CHO, and the ratio of high density lipotrotein (HDL)-CHO/T-CHO. The liver triglyceride (TG) and glycogen contents were also significantly lower in the MT group mice than in the DC group. The small intestine disaccharidase activity was analyzed to understand the therapeutic effects and the mechanism of MT water extracts in diabetic animals. MT group mice showed reduced lactase and sucrase activity in the proximal part of the small intestine. On the other hand, body weight, plasma insulin, TG, HDL-CHO, and hepatic T-CHO levels were similar in the DC and MT groups. Conclusion: These results suggest that MT water extracts have antidiabetic effects and can be developed as a functional source to reduce the postprandial blood glucose or to prevent DM incidence.
