본 연구는 5주간의 고지방 식이(45% 지방)가 복강 대식세포의 면역 반응에 미치는 효과를 분석하였다. C57BL/6 마우스(4주령, N=16)를 2집단으로 나누어 고지방 식이집단(HD, N=8)은 45% 지방 함량 고지방식이를 정상 식이집단(ND, N=8)은 정상식이(10% 지방)를 5주간 실시하였다. 복강 대식세포는 복강세척법을 이용하여 획득하였으며, LPS (lipopolysaccharide, $1{\mu}g/ml$, 24시간)를 이용하여 배양하였다. 체중은 고지방식이 후 유의하게 증가하였으며, LPS 처치 후 HD그룹의 산화질소, IL-$1{\beta}$ 및 IFN-${\gamma}$ 생성량은 ND그룹에 비하여 유의하게 낮았다. 그러나 두 집단에서 TNF-${\alpha}$와 IL-12의 생성량은 유의한 변화가 없었다. 이러한 결과는 비만 시 대식세포의 식균작용, 산화질소, IL-$1{\beta}$ 및 IFN-${\gamma}$ 생성량이 낮아짐에 따라 면역반응과 항원자극 감수성이 저하되는 것으로 사료된다.

The goals of this study were, first, to evaluate the feasibility of inducing gastric perforation with 99% alcohol injection after electrocautery (EA-method), and, second, to observe "enhanced peritoneal stripe sign (EPSS)" and other lesions upon induction of gastric perforation. Six clinically normal beagle dogs were prepared for gastric perforation using endoscopy. After gastric perforation, EPSS and other lesions on ultrasonography were observed eventually (at 0 h, 3 h, day 1, day 2, day 3, day 4, day 5, and day 6). We graded the EPSS depending on its width and number. EPSS was observed until day 4 of the examination in all the 6 dogs. The grades of EPSS were the highest at 3 h and declined gradually. Peritoneal effusion was observed in all dogs at 3 h and on day 1. Regional bright mesenteric fat was confirmed in all dogs on days 3 and 4. In conclusion, gastric perforation can be induced by EA-method. EPSS and peritoneal effusion appear at a very early stage, and regional bright mesenteric fat was identified on days 3 and 4 in almost all dogs with gastric perforation.

Background: Dynapenic obesity and sarcopenic obesity increase cardiovascular disease (CVD) and mortality in nonuremic patients. The present study was designed to determine the prevalence of dynapenic obesity and sarcopenic obesity and their associations with CVD risk factors in peritoneal dialysis (PD) patients. Methods: All eligible PD patients in Tehran peritoneal dialysis centers were included in this cross-sectional study. Skeletal muscle mass and fat mass were assessed using bioelectrical impedance analysis. Muscle strength and physical performance were determined using hand grip strength and a 4-meter walk gait speed test, respectively. In addition, a 5-mL blood sample was obtained from each patient. Results: The prevalence of dynapenic obesity and sarcopenic obesity were 11.4% and 3.8% in PD patients, respectively. Serum high-sensitive C-reactive protein (hs-CRP), soluble intercellular adhesion molecule type 1, triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly higher in PD patients with dynapenic obesity than in dynapenic nonobese and nondynapenic nonobese patients. Similarly, serum concentrations of CVD risk factors in PD patients with sarcopenic obesity were higher than in nonsarcopenic nonobese patients, but these differences were statistically significant only for serum hs-CRP and triglyceride. In addition, muscle strength and skeletal muscle mass percentage were negatively associated with markers of inflammation and dyslipidemia, whereas body fat percentage was positively associated with these CVD risk factors. Conclusion: This study indicates that although the prevalence of dynapenic obesity and sarcopenic obesity are relatively low in PD patients, these disorders may be associated with CVD risk factors.

The purpose of this research was to investigate the effect of Kamidangkwieumja(KDEJ) water extract on the allergy reaction in mice. The results were obtained as follows: 1. The passive cutaneous anaphylaxis induced by egg albumin in fat was not affected. 2. The lethal anaphylaxis induced by platelet activating factor in mice. was inhibited. 3. The degranulation of peritoneal mast cells induced by compound 48/80 was not affected. 4. The acute hind paw edema was inhibited after 2hours later when it was induced by histamine. 5. The permeability of evans blue into peritoneal cavity induced by acetic acid was not affected. 6. Arthus reaction in mice was not affected. 7. The delayed type hypersensitivity induced by SRBC was inhibited. 8. The contact dermatitis induced by DNFB was not affected. 9. The hemagglutination titer induced by SRBC was inhibited. 10. The writhing syndrome induced by acetic acid was inhibited. 11. The population of heper T cells in mice thymus was enhanced. 12. The phagocytic activity of peritoneal macrophages was enhanced. 13. The production of nitric oxide from peritoneal macrophages was not affected. These results suggest that the anti-allergy effect of KDEJ is caused by steroidlike and enhanced immune action. The steroidlike action of KDEJ correspond with steroid-applying-method that frequently used in clinic, so it is used io treatment of psoriasis. The research on anti-allergy of KDEJ might has to be continued.

Background: Body fats, especially both of abdominal fat pad mass and skeletal muscle fat content, are inversely related to insulin action. Therefore, methods for decreasing visceral fat mass and muscle triglyceride content may be helpful for the prevention of insulin resistance. Methods: Thalidomide, used for its anti-angiogenic and anti-inflammatory properties, was administered to rats for 4 weeks. A 10% solution of thalidomide in dimethyl sulfoxide was injected daily into the peritoneal cavity as much as 100 mg/kg of body weight. Results: The total visceral fat pad mass in the thalidomide-treated group was 11% lower than in the control group. The size of adipocytes of the epididymal fat pad mass in the thalidomide-treated group was smaller than in the control group. The intraperitoneal thalidomide treatment increased triglyceride concentrations by 16% in the red muscle, but not in the white muscle. Conclusion: The results suggested that intraperitoneal thalidomide treatment inhibited abdominal fat accumulation, and that the free fatty acids in the blood were preferentially accumulated in the red muscle rather than in the white muscle.

Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.

GyeongshinhaeGihwan T1 (GGT1) is a newly developed oriental medicine to help weight control. We investigated nitric oxide production and cytokine secretion in mouse peritoneal macrophages. According to recent reports, macrophages are participated in fat accumulation and closely related with obesity. In this study, using mouse peritoneal macrophages, we have examined whether GGT1 affects the production of nitric oxide (NO), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), and interleukin (IL)-12 by the stimulation of interferon-${\gamma}$ and lipopolysaccharide (LPS). GGT1 inhibits LPS-induced NO production in a dose-dependent manner. The decrease in NO synthesis was reflected as a decreased amount of inducible NO synthese protein. We also found that GGT1 inhibits pro-inflammatory cytokines, TNF-${\alpha}$ and IL-12 production. In mouse embryo preadipocyte 3T3-L1, GGT1 reduced the viability in a dose-dependent manner. These findings suggest that GGT1 may have potential effects in preventing and controlling adipogenesis and obesity.

An 11-year-old, intact male Cocker Spaniel dog was presented with history of abdominal distension, dyspnea for 10 days and lethargy for 1 day. Abdominal radiographs showed decreased serosal detail with abdominal distension. Abdominal ultrasounds revealed gallbladder mucocele with generalized peritonitis showing stellate-like sludge in the gallbladder with echogenic fat degeneration of cranial abdomen and abdominal free fluid containing echogenic materials. Loss of gallbladder wall integrity was shown clearly on computed tomography but ambiguously on ultrasound. Ultrasound-guided abdominocentesis was performed and showed amount of yellowish-bloody peritoneal fluid with vegetable matter and mucoid substance. On peritoneal fluid analysis, bilirubin level was elevated over three times than those of the serum. On exploratory laparotomy, gallbladder rupture and generalized bile peritonitis with intestinal adhesions were confirmed and cholecystectomy with peritoneal lavage was performed. One day after operation, patient died. This report describes delayed clinical symptoms of gallbladder rupture by gallbladder mucocele. In addition, this is the first case report using computed tomography made a diagnosis gallbladder rupture in a dog. Computed tomography might be helpful to diagnose gallbladder rupture.

Obesity can be defined as a metabolic disease due to an increased fat accumulation in the body caused by an imbalance of calorie intake and output The prevalence of obesity has increased substantially over the past 2-3 decades in developed and developing countries. The health impact of weight gain is so marked that obesity has now been classified as a major global public health problem In order to investigate the effect of diet conversion and oral administration of Platycodon grandiflorum extracts on the treatment of obesity, male Spraque-Dawley rats were divided into four groups: a group converted to normal diet (Control group), a group maintained high fat (30%) diet (H), and two groups with Platycodon grandiflorum extract added to the previously mentioned two groups. All animals were fed high fat diet for 7 weeks to induce the obesity. Then they were divided as mentioned above. Animals were fed experimental diet and Platycodon grandiflorum extract (150 mg/ml/rat/day) for 7 weeks. Body weight, adipose tissue weight (subcutaneous, epididymal, peritoneal fat pads) and serum lipids (total cholesterol and triglyceride) showed some differences among groups. The Platycodon grandiflorum feeding markedly decreased both body weight and adipose tissue weight in control group compared to H, high fat diet maintaining, group. Platycodon grandiflorum extracts significantly decreased the concentrations of serum lipids compared to H group. Fat cell numbers and sizes were significantly reduced in the oriental medicinal herb extract administrated group. Increased fatty acid binding protein (FABP) expression in high fat diet group was decreased by the dietary conversion to normal diet and the oral administration of Platycodon glandiflorum extracts. In contrast, there was no significant effect on FABP expression in the high fat maintenance group. In this study, the conversion from high fat diet to low fat or normal diet had a beneficial effect on body weight loss and serum lipid profiles. Dietary Platycodon glandiflorum extracts had an additive beneficial effect on the prevention and treatment of obesity.
