Onion (Allium cepa L.) is one of the richest sources of flavonoids in human diet. Onion peel contains over 20 times more quercetin than onion flesh. In this study, we studied the effects of onion peel water extract (OPE) on the blood lipid profiles in mice. The onion peel extracts was extracted with hot water. The experimental groups were divided with 3 groups (n = 6) of ICR male mice: normal diet + distilled water (NC), high-fat diet + distilled water (HF), high-fat diet + onion peel water extract 20 mg/kg (OPE-20). The oral administration was conducted daily. The experimental period was 7 weeks. Onion peel water extract showed higher concentration of polyphenol gallic acid and anti-oxidant trolox equivalent than the ethanol extract. The body weight gain and food efficiency ratio was significantly lower in the OPE-20 group as compared with HF group (p < 0.05). The epididymal fat and retroperitoneal fat showed significantly lower weights and sizes in the OPE-20 group as compared with HF group (p < 0.05). The serum levels of total cholesterol, LDL cholesterol and triglyceride were significantly lower in the OPE-20 group as compared with HF group (p < 0.05). The OPE-20 group showed higher HDL cholesterol concentration than HF group (p < 0.05). Atherogenic index was ignificantly lower in as compared with HF group (p < 0.05). The serum levels of glucose, GOT and GPT were significantly lower in the OPE-20 group as compared with HF group (p < 0.05). In these results, we suggests that onion peel water extracts supplementation can reduces the serum lipid components and improves the lipid metabolism in hyperlipidemic mice induced with a high-fat diet.

Angiopoietin-like protein 4 (ANGPTL4) is involved in a variety of functions, including lipoprotein metabolism and angiogenesis. To reveal the role of ANGPTL4 in fat metabolism of sheep, ovine ANGPTL4 mRNA expression was analyzed in seven adipose tissues from two breeds with distinct tail types. Forty-eight animals with the gender ratio of 1:1 for both Guangling Large Tailed (GLT) and Small Tailed Han (STH) sheep were slaughtered at 2, 4, 6, 8, 10, and 12 months of age, respectively. Adipose tissues were collected from greater and lesser omental, subcutaneous, retroperitoneal, perirenal, mesenteric, and tail fats. Ontogenetic mRNA expression of ANGPTL4 in these adipose tissues from GTL and STH was studied by quantitative real time polymerase chain reaction. The results showed that ANGPTL4 mRNA expressed in all adipose tissues studied with the highest in subcutaneous and the lowest in mesenteric fat depots. Months of age, tissue and breed are the main factors that significantly influence the mRNA expression. These results provide new insights into ovine ANGPTL4 gene expression and clues for its function mechanism.

Immunoglobulin G4 (IgG4) related autoimmune diseases are characterized by high serum IgG4 concentrations, sclerosing inflammation of numerous IgG4-positive lymphoplasma cells of varying origin, and a positive response to steroid treatment. Autoimmune pancreatitis, sclerosing cholangitis, and retroperitoneal fibrosis are representative presentations of IgG4 related autoimmune disease. Herein, we describe 2 patients (40-years-old woman and 47-years-old man) diagnosed with pulmonary involvement of IgG4-related autoimmune disease. The patients were admitted for an evaluation of the lung mass or multiple lung nodules found on chest radiography. Surgical lung biopsies were performed and pathologic finding revealed lymphoplasmacytic sclerosing inflammation with numerous IgG4 positive cells. The patients had elevated serum total IgG and IgG4 levels. Treatment consisted of high dose methylpredinisolone (1 mg/kg/day) and demonstrated good responsiveness. However, one patient experienced 2 relapses while being tapered off of steroid treatment.

The herb of Allium victorialis var. platyphyllum (Liliaceae) has been used as an edible wild herb and to treat heart failure and gastritis. We have already reported antihyperlipidemic anti-tumor effects of this plant. To enlarge the commercial availability of this food, it was investigated whether the extracts of A. victorialis var.platyphyllum reduce hyperlipidemia and obesity or not. The plants tested in this experiment were collected from two eco-types of IS. Ullung and Mt. Odae cultivated at Pyongchang. Extracts were prepared by extracting the fresh leaves and those dried at $36^{\circ}C$ and $90^{\circ}C$, respectively. Pretreatment with the ethanolic extracts for two weeks (p.o.) reduced serum triglyceride-, total cholesterol- and LDL-cholesterol contents in rats induced by Triton WR-1339, respectively. Furthermore, oral administration of the extracts also inhibited the hyperlipidemia induced with oral diet of 30% corn oil. In the other attempt to find to alleviate the obesity, the model rats with obesity were induced by the high fat-diet for six weeks. Post-treatment with the extracts for two weeks significantly reduced the hyperlipidemia. Retroperitoneal-, epidymal- and total abdominal fat pad weights were considerably reduced at 100 mg/kg oral administration of the extracts. Increased feces lipid contents were also found in the rat treated with the extracts. The extract of Mt. Odae eco-type showed more potent activity than that of Is. Ullung one. These results suggest that use of the fresh leaves may lead to the higher activity in treatment of hyperlipidemia and obesity than of the dried one.

Teratoma contains elements derived from all three embryonic germ layers and mature teratomas are entirely composed of mature differentiated tissues, while immature types always contain additional embryonic tissues of variable degree of immaturity, especially neuroepithelial elements. Twenty cases of teratoma in infancy and childhood were reviewed and the clinical features and pathologic findings including PCNA expression were studied. Sacrococcygeal teratomas were the most common type(45%), followed by retroperitoneal and ovarian teratomas. There was a predilection of females in a ratio of 4:1 and age distribution was most prevalent below the first year of age(45%). But in ovarian teratomas, the age at diagnosis was above 4 years of age in all cases. Serum alpha-fetoprotein levels were checked in 18 cases. In all mature teratomas and 1 of 5 immature teratomas, the levels were normal. But in 4 of 5 immature teratomas, the serum levels were elevated and progressively declined to normal range after mass excision. Radiologically, calcifications in tumor were found in 60.0% of teratomas and was higher in mature teratomas(69.2%) than immature teratomas(42.9%). Immunohistochemical staining for PCNA(proliferating cell nuclear antigen) was done in 16 cases and PCNA expression was higher in grade III immature teratomas than grade I and II. The operative modes were complete mass excisions. Five immature teratomas were treated with multiagent PEB(Bleomycin, Etoposide, Cisplatin) adjuvant chemotherapy, 3 tolerated well without significant complications, but in one case, severe bone marrow suppression was developed and died of sepsis. In conclusion, grade III immature teratoma showed higher PCNA expression than mature or lower grade immature teratoma, which suggests that chemotherapy after surgical excision may be effective modality for grade III immature teratoma. We think, however, multicenter study is necessary because of low incidence of immature teratoma.

Purposes: Pancreatic injury is rare in abdominal trauma patients (3%~12%). but it could result in significant morbidity and even mortality. Early and adequate decision making are very important in the management of patients with traumatic pancreatic injury. The purpose of this study was to assess the kinds of management and outcome through the review of our experience of pancreatic injury with multiple trauma. Methods: We reviewed 17 patients with traumatic pancreas injury via electronic medical records from Jan. 2002 and April. 2011. We collected demographic findings; the type, location and grade of pancreas injury, the treatment modality, and patient's outcomes, such as complications, length of hospital stay (LOS), and mortality. Results: Total 17 patients were reviewed, and man was 13 (88%). Traffic accident was the most common cause of injury. Pancreas neck was the most common injured site, and occured in 5 patients. Ductal injury was detected in 7 cases. Eleven patients were treated by surgical procedure, and in this group, 3 patients underwent the endoscopic retrograde pancreas drainage procedure coincidently. ERPD was tried in 8 patients, and failed in 2 patients. The major complications were post-traumatic fluid collection and abscess which accounted for 70 % of all patients. The hospital stay was 35.9 days, and it was longer in patient with ductal injury ($38.0{\pm}18.56$ vs. $34.5{\pm}33.68$ days). Only one patient was died due to septic shock associated with an uncontrolled retroperitoneal abscess. Conclusion: Early diagnosis is the most important factor to apply the adequate treatment option and to manage the traumatic pancreas injury. Aggressive treatment should be considered in patients with a post-operative abscess.

The effect on body fat accumulation on male Wistar rats undergoing continuous feeding with a histidine-enriched diet was investigated. Five-week-age rats were assigned to two groups and were fed either the control diet (purified diet AIN-$76^{TM}$) or the histidine-enriched diet containing 3% histidine for 28 days. It was observed that both adipose tissue masses in retroperitoneal and epididymal areas of rats fed histidine-enriched diet significantly decreased (p<0.05) compared to those of control rats, while there was no significant difference in the food efficiency ratio between them. The blood levels of histidine derivatives of 3-methylhistidine and carnosine were significantly (p<0.05) increased in the rats fed a histidine-enriched diet, whereas there were no significant different between the histidine-enriched diet and control groups in the general amino acid distribution. Our results demonstrate that a histidine-enriched diet suppresses body fat accumulation in rats.

Due to its safety and softness, autologous fat transplantation has been commonly performed for soft tissue correction. However, the injected fat is absorbed resulting in the reduction of volume of the graft by 40-60% within a few months. Thus, there was an attempt to use adipocytes differentiated from preadipocytes in vitro for transplantation. Differentiated adipocytes were biocompatible and matured with gradual volume increase at transplantation site in clinical study(unpublished data). In addition, they did not induce immune rejection in response to nonself lymphocytes in a mixed lymphocyte reaction(MLR)(unpublished data). The purpose of this study is to differentiate mouse preadipocytes following labeling into adipocytes to establish an animal model for allogenic transplantation. Preadipocytes isolated from inguinal and retroperitoneal fat pad of C57BL/6 mice were proliferated with growth medium by passage 3 and differentiated into adipocytes with different culture conditions after labeled with BrdU. At most suitable conditions, above 90% of preadipocytes were differentiated and BrdU labeling did not affect differentiation rate and function of differentiated adipocytes. These results demonstrate that BrdU-labeled adipocytes resulting from this in vitro differentiation protocol are useful for allogenic transplantation study.

The ganglion impar is a solitary retroperitoneal structure at the caudal end of the paravertebral sympathetic chain. Block of this ganglion has been advocated as a means of managing intractable perineal pain. In 1990, Plancarte et al performed a neurolytic block of the ganglion impar using 4-6 ml of 10% phenol through the intergluteal skin over the anococcygeal ligament. However, technical difficulties are encountered with the placement of the needle while performing this technique, with complications from the injection of phenol also being a possibility. In 1995, a modified approach for blocking the ganglion impar through the sacrococcygeal ligament was introduced by Wemm and Saberski. We used a radiofrequency (RF) lesion generator to create a controlled and localized lesion with a lower incidence of neural damages compared to chemical neurolysis. RF thermocoagulation of the ganglion impar through the sacrococcygeal ligament was performed on a 70-year-old male patient with constant anal pain using a curved TEW electrode. The patient has been relieved of his pain, without serious complication. Therefore, this technique may be an easier and safer approach, which is associated with fewer chances of complications.
