Vinegar is a very popular ingredient used in many cuisines. It is also known for its beneficial health, beauty and possible weight-loss properties. The authors report on a patient who presented to the emergency department with unstable vital signs complaining of generalized abdominal pain after ingestion of 450 ml of apple cider vinegar. We documented a case of corrosive gastrointestinal injury with persistent metabolic acidosis occurring after ingesting apple cider vinegar with an acetic acid concentration of 12~14%. Toxic damage to the liver and kidney were also observed, peaking on post-ingestion day 3. The patient received supportive care and hemoperfusion for three days without much clinical improvement and died in the seventh day of intensive care due to disseminated intravascular coagulation and multi organ failure. Edible vinegar, when taken in large amounts, is capable of inducing corrosive injuries of the GI tract as well as severe systemic toxicities, such as metabolic acidosis. Safety precautions regarding vinegar deserve more public attention and clinicians also should be astute enough to recognize the potential damage accompanying vinegar ingestion.

Objectives : HT042 is a combination of three herbal extracts from the roots of Astragalus membranaceus, the stems of Eleutherococcus senticosus and the roots of Phlomis umbrosa, which has been demonstrated to increase longitudinal bone growth rate. The aim of this study was to assess the safety of HT042 after repeated oral administration. Methods : A 14-day repeated oral dose toxicity study was conducted using male and female Sprague-Dawley rats. HT042 was administered orally at repeated doses of 500, 1,000 and 2,000 mg/kg/day for 14 days. Clinical signs and mortality were observed daily, whereas body weight and food consumption were recorded weekly throughout the experiment. At the end of the study, blood was taken from the posterior vena cava for hematology and serum biochemistry. All organs of the body surface, subcutis, head, thoracic cavity, and abdominal cavity were observed grossly. Then, the internal organs were removed and weighed. Results : No death occurred and no significant changes in clinical sign, body weight, food consumption and serum biochemistry parameters were observed in male and female rats over the study period. Although there were some alterations in hematologic and necropsy findings, and organ weights, these changes were not considered toxicologically significant. Conclusions : These results suggest that the 14-day repeated administration of HT042 does not produce any significant oral toxicity at doses of up to 2,000 mg/kg/day in male and female rats under the present experimental conditions.

The purpose of this study was to report an anaphylaxis after treated with Bee-venom acupuncture. Anaphylaxis is a clinical syndrome characterized by the acute system reaction of multiple organ systems to an IgE-mediated immunologic mediator release in previously sensitized individuals. We investigated the patients who had injected with Bee-venom in our clinic from March 2, 2014 to May 30, 2015. and two patients of anaphylaxis treated by Bee-Venom acupuncture were observed. One case of anaphylaxis was expressed clinically hypotension drowsy mentality, dyspnea, vomiting and so on. The other case was expressed itching sensation, urticaria, breathlessness, abdominal pain and so on. Based on this case, Bee venom-induced anaphylaxis can occur although preceding reactions are local or mild systemic ones. So, Korean medical doctor using Bee-Venom acupuncture must be prepare the system consider a countermeasure by anaphylaxis.

$Dioscorea$ $batatas$ Decne is a type of yam that eaten raw and used as a traditional oriental medicine in Asian countries. In this study, we evaluated the functional effects of yam water extracts on body weight levels and serum lipid concentrations in mice fed high fat diet. Mice were divided into four groups: normal diet control (ND), high fat diet control (HFD), HFD+yam extract 100 mg/kg (HFD-Y100), and HFD+yam extract 200 mg/kg (HFD-Y200). Yam extract was administrated orally to mice fed a high fat diet for 5 weeks. Treatment with yam extract significantly reduced body weight levels and energy efficiency in a dose-dependent manner in HFD-fed mice. Yam extract also attenuated serum levels of triglyceride, total cholesterol, and LDL-cholesterol, as well as organ weights of liver and abdominal adipose tissue in mice fed a high fat diet. Moreover, blood levels of glucose, insulin, and leptin significantly decreased in a dose-dependent manner upon administration of yam extract. Blood activities of GPT, GOT, and LDH were lower in the yam extract-treated groups compared to the HFD group. These results indicate that yam water extract may reduce elevated body weight and serum lipid concentrations in mice fed a high fat diet, suggesting its usefulness as a functional food for reducing body fat and hyperlipidemia.

Obesity is a major risk factor for cardiovascular disease. In our case study using animal models for disease states such as obesity or hypertension, we found that, Isaria sinclairii remarkably reduced body weight and ameliorated metabolic abnormalities in Zucker and SHR rats. Genetically obese (fa/fa) Zucker rats were one animal model chosen for this study. Four groups of rats received a standard diet and were treated orally with the following test samples daily for 8 weeks: saline (negative control), ethanol extracts of I. sinclairii, hot water extract of I. sinclairii, or $Xenical^{(R)}$ (30 mg/kg, positive control). Mild reductions (6.3%) in body weight gain were observed in the groups treated with the hot water extract of I. sinclairii compared to the control after 8 weeks. Interestingly, organ weight was greatly reduced by this Dongchunghacho (I. sinclairii), in parallel with the mild reductions in body weight gain and reductions in abdominal fat (adipose tissue). Also observed was a 4.1 % decrease in the ratio of heart weight/body weight compared to the control group. As a hypertensive animal model, SHR (spontaneously hypertensive rat) and WKY (Wistar Kyoto) rats were also administered these extracts for one month. Treatment with the hot water extract of I. sinclairii caused greater reductions in body weight gain for the SHR group (10.9%) compared to the WKY group's (5.2%). Based on these results, I. sinclairii extracts contain selective action for anti-obesity activity, naturally occurring candidate for regulation of body weight increase, as demonstrated in the present study.

Purpose: Traumatic pancreatic injuries are rare, but their diagnosis and management are challenging. The aim of this study was to evaluate and report our experiences with the management of pancreatic injuries. Methods: We identified all adult patients (age >15) with pancreatic injuries from our trauma registry over a 7-year period. Data related to patients' demographics, diagnoses, operative information, complications, and hospital course were abstracted from the registry and medical records. Results: A total of 45 patients were evaluated. Most patients had blunt trauma (89%) and 21 patients (47%) had pancreatic injuries of grade 3 or higher. Twenty-eight patients (62%) underwent laparotomy and 17 (38%) received nonoperative management (NOM). The overall in-hospital mortality rate was 24% (n=11), and only one patient died after NOM (due to a severe traumatic brain injury). Twenty-two patients (79%) underwent emergency laparotomy and six (21%) underwent delayed laparotomy. A drainage procedure was performed in 12 patients (43%), and pancreatectomy was performed in 16 patients (57%) (distal pancreatectomy [DP], n=8; DP with spleen preservation, n=5; pancreaticoduodenectomy, n=2; total pancreatectomy, n=1). Fourteen (31%) pancreas-specific complications occurred, and all complications were successfully managed without surgery. Solid organ injuries (n=14) were the most common type of associated abdominal injury (Abbreviated Injury Scale ≥3). Conclusions: For traumatic pancreatic injuries, an appropriate treatment method should be considered after evaluation of the accompanying injury and the patient's hemodynamic status. NOM can be performed without mortality in appropriately selected cases.

Congenital neuroblastoma is a rare disease. Placental metastasis is extremely rare and poor prognosis has been reported in neonates. Mirror syndrome could occur in mother with placental metastasis with possibilities of hypertension and edema. We report a case of detection of left suprarenal mass in fetus at $31^{+5}weeks^{\prime}$ gestation. Mother presented with palpitation, edema, headache, and hypertension. Maternal 24 hours urine vanillylmandelic acid (VMA) and normetanephrine (NME) level at 34 weeks' gestation were elevated. Consequently, emergent cesarean section was done. Based on abdominal ultrasonography and whole body magnetic resonance imaging, left adrenal tumor with liver metastasis was suspected. Neuroblastoma was confirmed by liver and placenta biopsy. Chemotherapy was started with Pediatric Oncology Group 9243 at day 7 and changed into Children's Oncology Group 3961 due to cholestasis and poor response during 2nd cycle. Plasma exchange was done for aggravated direct hyperbilirubinemia. The baby expired at 73 days due to multi-organ failure. Maternal symptoms were completely resolved in 2 weeks after delivery along with normalization of the elevated level of VMA and NME. We report a first case of mirror syndrome in Korean mother and fetus resulting from metastatic congenital neuroblastoma to placenta.

Alagille syndrome (AGS) is a rare autosomal dominant inherited disorder, with major clinical manifestations of bile duct paucity, cholestasis, cardiovascular anomaly, ophthalmic abnormalities, butterfly vertebrae, and dysmorphic facial appearance. It is caused by heterozygous mutations in JAG1 or NOTCH of the Notch signaling pathway presenting with variable phenotypic penetrance and involving multiple organ systems. The following case report describes a unique case of a 16-year-old female with AGS who presented with the primary complaint of renovascular hypertension. She had a medical history of ventricular septal defect and polycystic ovary syndrome. The patient had a dysmorphic facial appearance including frontal bossing, bulbous tip of the nose, a pointed chin with prognathism, and deeply set eyes with mild hypertelorism. Stenoocclusive changes of both renal arteries, celiac artery, lower part of the abdominal aorta, and left intracranial artery, along with absence of the left internal carotid artery were found on examination. Whole exome sequencing was performed and revealed a pathologic mutation of JAG1, leading to the diagnosis of AGS. Reverse phenotyping detected butterfly vertebrae and normal structure and function of the liver and gallbladder. While the representative symptom of AGS in most scenarios is a hepatic problem, in this case, the presenting clinical features were the vascular anomalies. Clinical manifestations of AGS are diverse, and this case demonstrates that renovascular hypertension might be in some cases a presenting symptom of AGS.

Liver transplantation is a critical used treatment method for patients with end-stage liver disease. The number of cases of living donor liver transplantation is increasing due to the imbalance in needs and supplies for brain-dead organ donation. As a result, the importance of the accuracy of the donor's suitability evaluation is also increasing rapidly. To measure the donor's liver volume accurately is the most important, that is absolutely necessary for the recipient's postoperative progress and the donor's safety. Therefore, we propose liver segmentation in abdominal CT images from pre-operation, POD 7, and POD 63 with a two-dimensional U-Net. In addition, we introduce an algorithm to measure the volume of the segmented liver and measure the hepatectomy rate and regeneration rate of pre-operation, POD 7, and POD 63. The performance for the learning model shows the best results in the images from pre-operation. Each dataset from pre-operation, POD 7, and POD 63 has the DSC of 94.55 ± 9.24%, 88.40 ± 18.01%, and 90.64 ± 14.35%. The mean of the measured liver volumes by trained model are 1423.44 ± 270.17 ml in pre-operation, 842.99 ± 190.95 ml in POD 7, and 1048.32 ± 201.02 ml in POD 63. The donor's hepatectomy rate is an average of 39.68 ± 13.06%, and the regeneration rate in POD 63 is an average of 14.78 ± 14.07%.
