Pancreas serves endocrine and exocrine functions in the body; thus, their pathology can cause a broad range of irreparable consequences. Endocrine functions include the production of hormones such as insulin and glucagon, while exocrine functions involve the secretion of digestive enzymes. Disruption of these functions can lead to conditions like diabetes mellitus and exocrine pancreatic insufficiency. Also, the symptoms and causality of pancreatic cancer very greatly depends on their origin: pancreatic ductal adenocarcinoma is one of the most fatal cancer; however, most of tumor derived from endocrine part of pancreas are benign. Pancreatitis, an inflammation of the pancreatic tissues, is caused by excessive alcohol consumption, the bile duct obstruction by gallstones, and the premature activation of digestive enzymes in the pancreas. Hereditary pancreatic diseases, such as maturity-onset diabetes of the young and hereditary pancreatitis, can be a candidate for disease modeling using human pluripotent stem cells (hPSCs), due to their strong genetic influence. hPSC-derived pancreatic differentiation has been established for cell replacement therapy for diabetic patients and is robustly used for disease modeling. The disease modeling platform that allows interactions between immune cells and pancreatic cells is necessary to perform in-depth investigation of disease pathogenesis.

Objective : Stent-assisted coil embolization (SAC) is commonly used for treating wide-neck intracranial aneurysms. In this study, we aimed to assess the clinical safety and efficacy of the NeuroForm Atlas Stent during SAC of intracranial aneurysms. Methods : We retrospectively analyzed data from patients with ruptured and unruptured cerebral aneurysms, who underwent SAC using the NeuroForm Atlas between February 2018 and July 2018. Favorable clinical outcomes and degree of aneurysm occlusion were defined as a modified Rankin scale score of ≤2 and a Raymond-Roy occlusion classification (RROC) class I/II during the immediate postoperative period and at the 6-month follow-up, respectively. Results : Thirty-one consecutive patients with 33 cases, including 11 ruptured and 22 unruptured cases were treated via NeuroForm Atlas SAC. Among the 22 unruptured cases with 24 unruptured aneurysms had favorable clinical outcome. Complete occlusion (RROC I) was achieved in 16 aneurysms (66.7%), while neck remnants (RROC II) were observed in six aneurysms (25%). Among the 11 patients with ruptured aneurysms, two died due to re-bleeding and diabetic ketoacidosis. In ruptured cases, RROC I was observed in eight (72.7%) and RROC II was observed in three cases (27.3%). At the 6-month follow-up, no clinical events were observed in the 22 unruptured cases. In the ruptured nine cases, five patients recovered without neurologic deficits, while four experienced unfavorable outcomes at 6 months. Of the 29 aneurysms examined via angiography at the 6-month follow-up, 19 (65.5%) were RROC I, eight (27.6%) were RROC II and two (6.9%) were RROC III. There were no procedure-related hemorrhagic complications. Conclusion : In this study, we found that stent-assisted coil embolization with NeuroForm Atlas stent may be safe and effective in the treatment of wide-neck intracranial aneurysms. NeuroForm Atlas SAC is feasible for the treatment of both ruptured and unruptured wide-neck aneurysms.

Hospital malnutrition could be caused by not completing the food served in the hospital. This has been a big problem since it delays the recovery of the patient and extends the length of hospital stay. The purpose of the study was to reduce the plate waste for the DM diet by performing several nutrition service improvement activities. The study was performed in a general hospital with 900 beds. A questionnaire survey was taken by 39 DM patients to obtain their aspect of the hospital foodservice systems and the quality of the meals at the beginning of the study. The amounts of foods served in the hospital kitchen and returned were measured by weights. After the improvement activities, the measurement of the plate waste was performed again for comparison. The average percentage of plate waste for the DM diet was 23.2%. The survey showed no difference by sex, age or duration of admission in plate waste. However, this food wastage percentage showed differences between the patients having a chance to get information about the diet therapy (12.21%) and not having one (26.06%) (p < 0.05). Using a five-point Likert-type scale, the quality of food by its taste was 2.49 (1: very poor, 5: excellent), the temperature score was 3.56 (1: very poor, 5: excellent), and the amount of food served score was 2.95 (1: very poor, 5: excellent), and the preference score was 3.13 (1: very dislike, 5: very like). Nutritional care improving activities were performed by adjusting seasonings, developing new menus, and standardizing cooking methods in order to increase the satisfaction of meal quality. The dietitian's inpatients care protocol was adjusted to expand the nutritional counseling chance for the DM patients. After the improvement activities, the average plate waste was reduced to 14.6%, and the satisfaction of food taste and preference increased to 3.21 (p < 0.001), and 3.36 (p < 0.05) correspondingly. The result shows that, for therapeutic diet patients, food intake could be increased by improving the food service satisfaction by controlling the meal quality and clinical nutritional service activities.

Backgrounds Diabetes mellitus is associated with accelerated atherosc lerosis and predispose to specific microvascular problems. This study was performed to evaluate the usefulness of red ginseng as adjunctive therapeutic agent of NIDDM especially in preventing chronic diabetic complications. Materials and Methods We treated 50 patients with NIDDM for 5 month with 2 regimens: 1)oralhypoglycemic drug therapy only(the control group), 2)oral hypoglycemic group). The patients were recruited at Korea university hospital from June, 1992 to October, 1992 and the following inclusion criteria were used: l)age above 35 years 2)initial body weight within or above ideal body weight 3)fasting blood glucose level greater than 140mg/dl 4)no previous history of diabetes mellitus or no history of blood glucose control for recent 3 months of more. The patients were seen every 2 weeks for remaining 3 months. At every visit FBS and PP2hr blood glucose were measured with blood pressure and body weight. Lipid profiles were checked every 4 weeks and platelet function test was perfomed with aggregometer after administration of ADP, epineprine and collagen every 4 weeks. Free fatty acid were also analyzed every 8 weeks and glycosylated hemoglobin was measured every 12 weeks. Results The results were as follows: 1. The mean values for fasting and PP2hr blood glucose decreased significantly in the control group than in the ginseng group. 2. The weight gain was less in the ginseng group than in the control group. The levels of systolic blood pressure decreased' significantly in the ginseng group than in the control group. 3. There was no significant differences of lipid profiles in both groups. 4. The platelet hyperaggregation was improved more significantly in the ginseng group than in the control group. Conclusions In patients with NIDDM who were recieving oral hypoglycemic drug therapy, the addition of red ginseng improved platelet function and blood pressure, but induced less weight gain. The data suggests that red ginseng may be useful as a therapeutic adjunct especially in preventing chronic complications of NIDDM.

Objectives : This study was to investigate the regulatory effect of electro-acupuncture on Jogsamni ($ST_{36}$) in bradygastric condition or gastroparesis which is a neuropathic complication of type 2 diabetes mellitus(T2DM), assessed using 4-channel electrogastrography (EGG). Methods : It was a case series study. Each patient was given electro-acupuncture(EA) one point, Jogsamni($ST_{36}$) or Gyeonu($LI_{15}$) bilaterally for thirty minutes with 2Hz bipolar square wave frequency and moderate intensity of stimulation. With attaching electrodes around stomach region throughout pre-acupuncture, acupuncture, and post-acupuncture session, these parameters were produced; percent rate of bradygastria power compared to sum of power in all kind of gastric rhythm(% bradygastria), dominant frequency(DF) and dominant power(DP). Parameter was analysed per each channel's variable change from pre-acupuncture session by paired t-test. Results : There was statistically significant decrease in % bradygastria parameters on one of the $ST_{36}$ treated patients from pre-acupuncture session and to post-acupuncture session(P=0.015, P=0.008 respectively). A marginal significant decrease of DP was shown in the other $ST_{36}$ treated patient from pre-acupuncture session through post-acupuncture session(P=0.049). Combined data of two $ST_{36}$ Treated patients showed that there was significant decrease of %bradygastria from pre-acupuncture session to acupuncture session(P=0.020), and was decrease of DP from pre-acupuncture session to post- acupuncture session(P=0.020). Conclusions : EA at $ST_{36}$ resulted in statistically significant decrease in %bradygastria and DP for dysrhythmic condition in T2DM gastroparesis patients. Considering this limited results, further study will be needed to elucidate the effect of multiple-acupuncture on gastric myoelectrical activities.

Objective: This study was conducted to evaluate the effect of herbal medicine on blood glucose in diabetic patients. Methods: The subjects were patients with diabetes mellitus (DM) who had been admitted to Kyung Hee University Korean Medicine Hospital for more than 8 weeks for a primary diagnosis other than DM and who had taken herbal medicine for more than 8 weeks from January 2010 to February 2020. The medical records were analyzed retrospectively to confirm the characteristics of the subjects, and examination results included hemoglobin A1c (HbA1c), total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine. Changes in HbA1c before and after taking herbal medicine and changes according to subgroups were analyzed. Results: A total of 149 subjects with type 2 DM were selected as participants. After taking the herbal medicine, the HbA1c value was significantly decreased, and the statistical significance was maintained even when the effect of controlling antidiabetic agents was excluded. The decrease in HbA1c was higher in the poor glycemic control group. Liver and kidney functions did not show any significant changes after taking the herbal medicine. Conclusions: Administration of herbal medicine for a long period of 8 weeks or longer did not increase HbA1c in patients with DM complicated by other various diseases.
