  • The purpose of this study was to investigate the effect of butanol (BuOH) fraction of Alisma canaliculatum (Ac) and/or selenium (Se) treatment on glycogen level, lipid metabolism and lipid peroxidation in streptozotocin (STZ)-induced diabetic rats. Male Sprague-Dawley rats were assigned to one of the five groups: normal, STZ-control, and three experimental groups (Ac group, Ac-Se group, and Se group). Diabetes was experimentally induced by intravenous administration of 45 mg/kg of STZ in citrate buffer. The BuOH fraction of Ac (400 mg/kg bw) was orally administered for 3 weeks. The Se group were fed a AIN-93 recommended diet mixed with Na$_2$SeO$_3$ (2 mg/kg diet). The liver glycogen level of Ac and Ac-Se groups were significantly higher, when compared with the STZ-control groups. The muscle glycogen level was not significantly differ among all groups. The levels of liver triglyceride were higher in Ac-Se group than the STZ-control group. Pancreas protein levels were significantly increased in Ac-Se group than STZ-control group. The concentration of liver malondialdehyde (MDA) was significantly decreased in Ac and Se groups and decreased in Ac-Se group. Administration of BuOH fraction of Alisma canaliculatum and selenium supplementation increased the liver glycogen and triglyceride levels, and reduced peroxidative liver damage in STZ induced diabetic rats. These results suggest that treatment with a BuOH fraction of Alisma canaliculatum in combination with selenium has no synergistic antioxidative effect. Selenium supplementation may lead a decrease MDA of liver in diabetic rats.

  • A folk prescription consisting of Alnus hirsuta, Rosa davurica, Acanthopanax senticosus and Panax schinseng has been used in the treatment of diabetes mellitus. The aim of the present investigation was to evaluate the antidiabetic effects of the herb formula extract (HFE) composed of Alnus hirsuta, Rosa davurica, Acanthopanax senticosus and Panax schinseng in the streptozotocin (STZ)-induced diabetic rats. The HFE was mixed in the food supply of the healthy and STZ-induced diabetic male Sprague-Dawley rats, and its effects on the body weight, water and food intake, hyperglycemia, hypolipidemic and islet structure were studied. The treatment of the rats with STZ for 6 weeks resulted in marasmus, polydipsia, polyphagia, hyperglycemia and hypoinsulinemia. In addition, the diabetic rats showed an apparent decrease in the insulin immunoreactivity and the number of ${\beta}$-cells in the pancreas. The addition of the HFE to the rats' food supply significantly lowered the serum glucose and the serum triglycerides level and preserved the normal histological appearance of the pancreatic islets. These results indicate that the HEF have a strong antidiabetic potential along with the significant hypoglycemic and hypolipidemic effects, which may be applicable in the pharmaceutical industry.

  • Experiments were conducted to determine the efficacy of modified montmorillonite nanocomposite (MMN) to reduce the toxic effects of aflatoxin (AF) in growing/finishing pigs. 96 weaned pigs were assigned to four dietary treatment groups (0 g of MMN and 0 mg of AF/kg feed, 3 g of MMN/kg feed, 0.1 mg of AF/kg feed, and 3 g of MMN plus 0.1 mg of AF/kg feed). Body weight gain (BW gain), feed/gain ratio, serum biochemical values and enzyme activities were evaluated. Compared with the control, AF alone markedly reduced BW gain and resulted in a significantly higher feed/gain ratio. There were no differences in BW gain and feed/gain ratio between 0.3% MMN or 0.3% MMN plus AF and the control. These results suggested that the deleterious effects of AF were ameliorated by MMN addition. AF intake markedly increased relative organ weights of liver, kidney, spleen and pancreas, and resulted in significant alterations of serum parameters. However, these parameters for pigs fed diets containing MMN and AF returned to normal values, indicating that MMN had the ability to recover the AF-decreased performance, organ damage and to correct aberrations in serum parameters. These findings in our study suggested that MMN can effectively modulate the toxicity of AF in growing/finishing pigs and may offer a novel approach to the preventive management of aflatoxicosis in animals.

  • This study aimed to examine the recognition on phlegm-retained fluid of the Onbo School's five physicians, Xue Ji(薛己), Sun Yi-kui(孫一奎), Zhao Xian-ke(趙獻可), Zhang Jie-bin(張介賓), and Li Zhong-zi(李中梓), who made important contributions in the formation of Tanbing theories. Five authors were included as the study subjects. The study examined on the definition, causes, classification, therapeutic methods, and instructions of phlegm-retained fluid. The results are Phlegm-retained fluid is formed when the normal circulation of body fluid is not functioning properly. Plegm (痰) is thick, slimy, and murky fluid. In contrast, retained fluid(飮) is clear and watery fluid. The major causal organs of phlegm-retained fluid formation were pointed out as pancreas and kidney. Five physicians had different opinions regarding the classification of phlegm-retained fluid. Warming and tonifing the spleen and stomach(溫補脾胃) and tonifing the kidney(補腎) were taken as the suitable methods for treating phlegm-retained fluid. The common characteristics of the Onbo School were verified in terms of formation and treatment methods for phlegm-retained fluid. However, specific common points were hardly found in other items. The Onbo School had varied opinions on the processing methods of Rehmannia glutinosa(熟地黃). Further discussion on related references are essential.

  • A 6-year-old intact female Shih-tzu dog was referred due to anorexia. Physical examination, complete blood count, serum chemical analysis, radiography, and ultrasonography were evaluated. Physical examination and hematological analysis showed normal findings. Abdominal radiographs and ultrasound revealed well-defined masses in the spleen. Other abdominal organs showed no significant abnormalities. Tissue samples taken via sono-guided fine needle aspiration of the splenic mass showed many bare nuclei, which were variable in size. Results of histopathological and immunohistochemical (IHC) analyses performed after splenectomy were consistent with paraganglioma. Based on these findings, we diagnosed this patient with a paraganglioma of splenic origin. Two months after splenectomy, abdominal ultrasonography revealed a new neoplastic lesion in the liver. The clients refused further management and the patient expired three months after initial diagnosis. Necropsy as well as histopathological and IHC examinations of other systemic organs including the liver, adrenal gland, kidney, brain, urinary bladder, lung, aortic body, carotid body, and pancreas were performed. The neoplastic tissue in the liver also demonstrated features of a paraganglioma, and there were no remarkable findings in all other organs.

  • Successful management of duodenal obstruction in newborn infant implies not only satisfactory nutrition but also achievement of normal growth. To aid early diagnosis and management, we evaluated the diagnostic methods, operative interventions and clinical characteristics of thirty-nine infants with congenital duodenal obstructions. In the 11-year period from July 1986 through June 1997, thirty-nine patients with congenital duodenal obstruction (23 males and 16 females) were treated and reviewed at the Department of Pediatric Surgery, Yeungnam University Hospital. The ratio of male to female was 1.4:1, and 29 cases(74.1%) among total 39 patients were newborn. There were 5 premature patients and 16 patients of small for gestational age. The most common causes of the congenital duodenal obstruction was malrotation (26 cases, 66.7%) and followed by annular pancreas (9 cases, 23.1 %), type 1 atresia (3 cases, 7.7%) and wind-sock anomaly (1 case, 2.6%). Common symptoms were vomiting, abdominal distention, jaundice. Plain abdominal X-ray study combined with upper gastrointestinal series was the most commonly used diagnostic method. The operative procedures were performed by same pediatric surgeon utilizing Ladd's procedure in 26, duodenoduodenostomy in 8, duodenojejunostomy in 4, excision of wind-sock membrane in 1. A total of 15 associated congenital anomalies were found in 9 patients. Postoperative complications occurred in 13(33.3%). Overall mortality was 2.6%(1/39). Bilious vomiting and plain abdominal radiologic study were most useful for the diagnosis of congenital duodenal obstruction. Early diagnosis and operative intervention were important to prevent complications such as sepsis and peritonitis.

  • Objectives : In this study, we aimed to investigate the effect of Eunhoebanchong-san (EBS) on caerulein-induced acute pancreatitis (AP) by detecting oxidative stress markers and performing histopathological examination. Methods : Thirty adult male Sprague-Dawley rats were divided into five groups as follows: normal (NOR), caerulein-induced (CON), caerulein+EBS (130 mg/kg, EA), caerulein+EBS (260 mg/kg, EB) and caerulein+EBS (520 mg/kg, EC) groups. Pancreatic tissues of rats from all groups were removed for apoptosis, and light, and electron microscopic examination. Blood of rats from all groups was obtained for oxidative stress markers and pathological examination. Pancreatic oxidative stress markers were evaluated by the measurements of serum amylase, and interleukin-6 (IL-6) levels were determined spectrophotometrically. Results : The ratio of pancreas/body weight increased significantly in the CON compared with the NOR, but decreased significantly in the EA, the EB, the EC groups compared with the CON. Caerulein administration resulted in a significant increase in amylase, but EBS reduced the levels of these enzymes. Interleukin-6 (IL-6) levels increased significantly in CON compared with NOR, but reduced in EA, EB, and EC group at 24 hrs. In the observations of optical microscopy and electron microscopy, the experimental groups showed significant decreases in pancreatic tissue inflammation, edema, vacuolization, necrosis compared to the control group. Altogether, this indicates EBS is potentially capable of limiting pancreatic damage produced during AP by restoring the fine structure of acinar cells and tissue. Conclusions : We concluded that EBS may have beneficial effects in the treatment of caerulein-induced AP.

  • 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.

  • G protein-coupled receptor 119 (GPR119) is expressed in the pancreas and gastrointestinal tract, and its activation promotes insulin secretion in the beta cells of the pancreatic islets as well as the secretion of glucagon-like peptide-1 (GLP-1) in intestinal L cells, consequently improving glucose-stimulated insulin secretion. Due to this dual mechanism of action, the development of small-molecule GPR119 agonists has received significant interest for the treatment of type 2 diabetes. We newly synthesized 1,2,4-triazolone derivatives of GPR119 agonists, which demonstrated excellent outcomes in a cyclic adenosine monophosphate (cAMP) assay. Among the synthesized derivatives, YH18968 showed cAMP=2.8 nM; in GLUTag cell, GLP-1secretion=2.3 fold; in the HIT-T15 cell, and insulin secretion=1.9 fold. Single oral administration of YH18968 improved glucose tolerance and combined treatment with a dipeptidyl peptidase 4 (DPP-4) inhibitor augmented the glucose lowering effect as well as the plasma level of active GLP-1 in normal mice. Single oral administration of YH18968 improved glucose tolerance in a diet induced obese mice model. This effect was maintained after repeated dosing for 4 weeks. The results indicate that YH18968 combined with a DPP-4 inhibitor may be an effective therapeutic candidate for the treatment of type 2 diabetes.

  • Metformin is antihyperglycemic, not hypoglycemic. It causes neither insulin release from the pancreas nor hypo glycemia, even when taken in large doses. But, there are several reports of metformin-associated lactic acidosis (MALT). We present a case report of severe lactic acidosis most probably resulting from high doses of metformin in a patient with no known contraindications for metformin. A 43-year-old female was admitted to the emergency department due to a metformin overdose. She had diabetes for 6 years, well-controlled with metformin and novolet. One hour before admission, she impulsively took 50g metformin (100 mg or 100 tablets). Physical examination for symptoms revealed only irritability, and laboratory evaluation revealed only mild leukocytosis. After one hour the patient was drowsy, and arterial blood gas analysis showed severe lactic acidemia Seven hours after ED arrival, she commenced hemofiltration treatment and was admitted to the intensive care unit. Continuous venovenous hemodiafiltration was initiated. Forty-eight hours later, full clinical recovery was observed, with return to a normal serum lactate level. The patient was discharged from the intensive care unit on the third day. A progressive recovery was observed and she was discharged from the general word on the thirteenth day.
