  • This study tried to integrate the traditional oriental medical theories and results of experimental studies of herbaceous plants on anti-diabetes. And I tried to analyze recent experimental study trend on the anti-diabetic herb. I searched anti-diabetic herb studies on 4 korean databases and 10 korean journals by keywords, 'diabetes', 'blood glucose', 'glycometabolism', 'pancreatic ${\beta}$-cell', etc. In order to see detail review, searching was performed from 2000 to 2010. And I searched 125 study cases concerning anti-diabetic herb and 72 varieties herbaceous plants used in study of anti-diabetes. and I analyzed the choice motives of each herb for anti-diabetic study, the extract methods and anti-diabetic evaluation contents. And I analyzed anti-diabetic herbs from a traditional oriental medical point of view. When the researchers chose herb for anti-diabetic experiment, just 8.8% of the choice was based on the oriental medical evidences. I found that 60.6% of the herb shown to be effective in diabetes experimentally had oriental medical theory-based Properties(性). There were studies with whole plants(16.8%), aqueous extract(45.6%), methanol extract(8.0%), ethanol extract(8.0%) and comparative studies of more than 2 types of extracts or various fractions(18.4%). The most frequent experimental diabetic models was diabetic mouse induced by streptozotocin(STZ)(87.8%). And there were db/db mouse(6.7%), ob/ob mouse(1.1%), etc. 33.6% of all studies just measured hematological indices of diabetes, and 66.4% researches analyzed details. To improve herbaceous plants study on diabetes, we oriental medical scientists have to integrate the oriental medical theories and results of experimental studies.

  • Objectives : In present study, therefore, possible beneficial pharmacological activities of standard potato protein extracts (SPE) were observed on the mild diabetic obese mice. Methods : After end of 12 weeks of continuous oral administrations of three different dosages of SPE 400, 200 and 100 mg/kg, or metformin 250 mg/kg, analyzed the hepatoprotective, hypolipidemic, hypoglycemic, nephroprotective and anti-obesity effects, separately. In addition, liver antioxidant defense systems were additionally measured with lipid metabolism-related genes expressions and hepatic glucose-regulating enzyme activities for action mechanism. Results : All of diabetes and related complications including obesity were significantly inhibited by treatment of SPE 400, 200 and 100 mg/kg, dose-dependently, and they also dramatically normalized the hepatic lipid peroxidation and depletion of liver endogenous antioxidant defense system, the changes of the hepatic glucose-regulating enzyme activities, also changes of the lipid metabolism-related genes expressions including hepatic $AMPK{\alpha}1$ and $AMPK{\alpha}2$ mRNA expressions, dose-dependently. Especially, SPE 200 mg/kg constantly showed favorable inhibitory activities against type II diabetes and related complications as comparable to those of metformin 250 mg/kg in HFD mice, respectively. Conclusions : The present work demonstrated that SPE 400, 200 and 100 mg/kg showed favorable anti-diabetic and related complications including obesity refinement activities in HFD mice, through AMPK upregulation mediated hepatic glucose enzyme activity and lipid metabolism-related genes expression, antioxidant defense system and pancreatic lipid digestion enzyme modulatory activities.

  • In the present study, Radix clematidis extract (RCE) was evaluated to determine if it could protect pancreatic ${\beta}$ cells against multiple low dose streptozotocin (MLDS)-induced diabetes. Injection of mice with MLDS resulted in hyperglycemia and hypoinsulinemia, which was confirmed by immunohistochemical staining. However, the induction of diabetes by MLDS was completely prevented when mice were pre-administrated with RCE. Generation of oxidative stress is implicated in MLDS, a ${\beta}$ cell specific toxin-induced islet cell death. In this context, to elucidate the mechanisms of protective effects in RCE pre-administrated diabetic mice, we investigated the expression of heme oxygenase-1 (HO-1), which is one of the anti-oxidant enzymes. MLDS-induced HO-1 expressions were significantly reduced in MLDS-treated mice. However, the decrease of HO-1 by MLDS were protected by pretreatment of RCE. The molecular mechanism by which RCE inhibits diabetic conditions by MLDS appears to involve inhibition of HO-1 expression. Taken together, these results reveal the possible therapeutic value of RCE for the prevention of type 1 diabetes progression.

  • Gastrointestinal involvement in Henoch-Sch$\"{o}$nlein purpura (HSP) is common. However, both acute pancreatitis and acute renal failure appear to be very rare complications of HSP. We describe a case of HSP with acute pancreatitis and hypovolemic acute renal failure in a 7-year-old girl who presented with a vasculitic purpuric rash involving the lower extremities, abdominal pain, hematochezia, vomiting, and oliguria. Laboratory findings showed increased serum levels of amylase, lipase, and creatinine. An abdominal CT scan revealed diffuse enlargement of the head and body of the pancreas. The patient was successfully managed with conservative treatment, including corticosteroids, and then her pancreatic enzymes and renal function returned to normal. Acute pancreatitis should be differentiated from other causes of acute abdomen in HSP to avoid unnecessary surgery.

  • Purpose: Choledochal cyst is a cystic dilatation of common bile duct. Although the etiology is presently uncertain, anomalous pancreaticobiliary ductal union (APBDU) is thought to be a major etiology of choledochal cyst. In this study, we analyzed the clinical and anatomical characteristics and pathologies of patients diagnosed with choledochal cyst in a single institute for 25 years. Methods: A total of 113 patients, diagnosed with choledochal cyst and who received an operation in Severance Children's Hospital from January 1988 to May 2013, were included. Medical records were reviewed, including clinical and demographic data, surgical procedures. Abdominal ultrasonography, magnetic resonance cholangiopancreatography, and intraoperative cholangiography were used as diagnostic tools for evaluation and classification of choledochal cyst and the presence of anomalous pancreaticobiliary ductal union. Todani's classification, and relationship between APBDU and surgical pathology. Results: Among 113 patients, 77 patients (68.1%) presented symptoms such as hepatitis, pancreatitis and/or cholecystitis. Eighty three patients (73.5%) had APBDU, and 94 patients (83.2%) showed inflammatory pathologic changes. APBDU, pathologic inflammation, and serological abnormalities such as hepatitis or pancreatitis showed a statistically significant correlation to one another. Conclusion: APBDU is thought to be one of the etiologic factors of choledochal cyst. It is related to the inflammatory changes in bile duct that can lead to the cystic dilatation.

  • Antidiabetic effects of the acid hydrolysate of silk fibroin were investigated by oral administration to animal models for diabetes mellitus, Fibroin protein was extracted from cocoon and digested to peptides of low-molecular weight range (mainly below 3,000) and amino acids by acid hydrolysis, Feeding of the fibroin hydrolysate resulted in a significant recovering effect on reduction of body weight gain and a lowering effect on blood glucose gain in streptozotocin-induced diabetic Sprague Dawley rats (STZ rats) which were used as an insulin-dependent diabetic animal model. But the body weight and blood glucose level in C57BL/KsJ-db/db mice (db/db mice), an non-insulin-dependent diabetic animal model, were not changed significantly by the feeding, On the other hand, plasma leptin levels increased according to increased feeding amount of the hydrolysate in STZ rats and db/db mice in common, It was concluded from the results that the fibroin hydrolysate might stimulate the insulin secretion by recovering or activating pancreatic ${\beta}$ cells and result in the increased plasma leptin level. It was also deduced that the antidiabetic improvements in body weight and blood glucose gain in STZ were thought to be due to the increased insulin secretion, but in db/db mice of which the diabetic symptoms were caused by insulin resistance, the stimulated secretion of insulin was unlikely to be able to change body weight and blood glucose level significantly.

  • Citrin deficiency (OMIN #605814) is an autosomal recessive disorder caused by the SLC25A13 gene mutation with abnormal biochemical findings, including increased serum ammonia, citrulline, arginine, galactose, serum threonine-to-serine ratio, serum pancreatic secretory trypsin inhibitor, and alpha-fetoprotein. Citrin deficiency can manifest in three ways: in newborns as neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD), in older children as failure to thrive and dyslipidemia caused by citrin deficiency (FTTDCD), and in adults as citrullinemia type 2 (CTLN2) with recurrent hyperammonemia and neuropsychiatric symptoms. We report a 35-day-old asymptomatic patient with citrin deficiency who had abnormal biochemical findings.

  • The triglycerides of walnut oil were fractionated by high performance liquid chromatography (HPLC) on the basis of partition number (PN). Each triglyceride was finally fractionated on the basis of aryl carbon numbers (CN) by gas-liquid chromatography (GLC). The fatty acids of triglyceride for each PN group were analyzed by GLC. Also, the fatty acid at ${\beta}-position$ of glycerol in each PN fraction separated by HPLC was determined by enzymatic hydrolysis with pancreatic lipase. The major triglyceride molecular species of walnut oil were $C_{18:2}{\cdot}C_{18:2}{\cdot}C_{18:1}$(LLO; 10.9%), $C_{18:3}{\cdot}C_{18:2}{\cdot}C_{18:2}$(LnLL; 17.6%) and $C_{18:2}{\cdot}C_{18:2}{\cdot}C_{18:2}$(LLL; 37.3%). The triglyceride molecular species occupied by unsaturated fatty acid at ${\beta}-position$ were more than 90%.

  • Objective : To compare the mortality rate of Korean medical doctors to that of the general Korean population for the period 1992-2002. Methods : The membership records of the Korean Medical Association were linked to the 1992-2002 death certificate data of Korea s National Statistical Office using 13-digit unique personal identification numbers. The study population consisted of 61,164 medical doctors with a follow-up period of 473,932 person-years. Standardized mortality ratios(SMRs) were calculated to compare cause-specific mortality rates of medical doctors to those of the general population. Results : We confirmed 1,150 deaths at ages from 30 to 75 years from 1 January 1992 to 31 December 2002. The SMR for all-cause of death was 0.47(95% CI : $0.44{\sim}0.50$). The SMRs for smoking-related diseases such as cerebrovascular accidents and chronic obstructive pulmonary disease were smaller than the SMR of all-cause of death. However, the SMRs for colorectal and pancreatic cancers were not significantly lower than those of the general population. Transport accidents and suicides accounted for 72% (94 of 131) of external causes of death. The SMR for suicide was 0.51 (95% CI : $0.38{\sim}0.68$). Conclusions : The mortality rate of South Korean medical doctors was less than 50% that of the general population of South Korea. Cause-specific analysis showed that mortality rates in leading causes of death were lower among medical doctors although differences in mortality rates between medical doctors and the general population varied with the causes of death. These health benefits found among medical doctors may be attributable to the lower level of health damaging behaviors (e.g., lower smoking rates) and better working conditions.

  • Purpose: Although the duodenum and the pancreas are protected by surrounding organs and have a low probability of injury during trauma, the mortality and the morbidity due to complications is high. This report includes the pancreaticoduodenal injuries we observed that were treated at a single institute. Methods: The medical records of patients admitted to our institute between 2001 and 2012 for pancreaticoduodenal injury were retrospectively reviewed. Results: In our hospital, between 2001 and 2012, 15 patients were admitted for a pancreaticoduodenal injury. All patients experienced blunt trauma, 6 of whom were involved in traffic accidents and 9 of whom received injuries from physical assault. Most of the patients were men(13 of 15 patients, 86%) with a mean age of 23 years (range, 5?39 years). All patients were admitted to the emergency center and managed by the surgeons on duty. The mean value of the injury severity score was 22. The mortality rate was 6%(1 of 15 patients). Seven of the fourteen surviving patients(50%) had duodenal injury, 6 patients(42%) had a pancreatic injury, and 1 patient(7%) had a combined pancreaticoduodenal injury. The surgical procedures were targeted at damage control. Conclusion: In conclusion, we believe that damage control surgery is the optimal management for a pancreaticoduodenal injury.
