  • Pediatric mesenteric panniculitis is an extremely rare disease of unknown etiology characterized by chronic inflammation, fat necrosis, and fibrosis in the mesenteric adipose tissue. A previously healthy 13-year-old boy was admitted because of right upper abdominal pain. An abdominal computed tomography scan revealed increased attenuation and enhancement in the left upper abdominal omental fat and anterior peritoneal wall thickening. A laparoscopic biopsy showed mesenteric panniculitis with chronic inflammation, adiponecrosis, and septal fibrosis. Serological tests for autoimmune diseases, nested polymerase chain reaction for Mycobacterium tuberculosis, and special immunohistochemical stains for malignancy were all negative. Symptomatic improvement and improved abnormal findings were achieved after an 8-month treatment with prednisolone according to a follow-up abdominal computed tomography scan. Here, we report a case of pediatric mesenteric panniculitis treated with prednisolone.

  • Although garlic has been reported to have impressive effects in lowering serum lipids, there have been controversial evaluations on these effects. To find the potential fator causing the inconsistency in the previous studies, we examined the effects of two types of garlic according to the producing-area (hangihyung garlic, nangihyung garlic) on serum lipid profiles and leptin level. Thirthy six of 4 wk old Sprague Dawley male rats fed high fat diet (40% of calories as fat) for 6 wks to induce obesity, and subsequently fed 5% garlic powder supplemented (HF+H: hangihyung garlic powder, HF+N: nangihyung garlic powder) high fat diets (w/w) for further 5 wk. For the comparison, normal control group fed AIN-76A diet (11.7% of calories as fat). Supplementation with hangihyung and nangihyung garlic resulted in a significant reduction of high fat induced body weight gain, white fat (i.e., epididymal, visceral and peritoneal fat) development, adipocyte hypertrophy and the development of hyperinsulinemia and hyperliptinemia. Serum triglyceride and total cholesterol level was greatly reduced by hangihyung garlic supplementation (p<0.05). The HDL-cholesterol level was increased by dietary hangihyung and nangihyung garlic. There were slight non-significant decreases in triglyceride and total cholesterol of HF+N group as compared to those of HF group. Leptin level of HF+H group was found to be significantly lower than HF group (p<0.05). There was no significant difference among N group and HF+N group. These results suggest that hangihyung garlic may lead to the higher activity in improving lipid profiles than nangihyung garlic. Whether the hypolipidemic effect of garlic increases in a species-dependent has yet to be determined and awaits further research.

  • Objectives: The object of this study was to observe antitumor, anticachexia and immunomodulatory effects of Shipyeukmiyeugi-eum(SYM) on human breast cancer cell, MCF-7, xenograft Balb/c nu-nu nude mice. Methods: Three different dosages of SYM-125, 250 and 500 mg/kg were orally administered once a day for 28 days from 11 days after tumor cell inoculation, and the changes on the body weights, tumor volume and weights, weights of spleen and popliteal lymph node and epididymal fat, serum IL-6 and IFN-${\gamma}$ levels, NK cell and peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were observed. In addition, histopathological observations of apoptotic cell, spleen, popliteal lymph node and cervical brown adipose were also detected. The results were compared with a potent cytotoxic estrogen receptor antagonist, Tamoxifen 20 mg/kg treated mice. Results: Tumor volumes and weights were decreased without cytotoxic effects on the both MCF-7 and MCF-10A cells as results of all three different dosages of SYM treatment. And weights of body, spleen, popliteal lymph node, epididymal fat, serum IFN-${\gamma}$, NK cell, peritoneal macrophage activities, splenic TNF-${\alpha}$, IL-$1{\beta}$ and IL-10 contents were increased with decrease of serum IL-6. At histopathological observations, apoptotic tumor cells, spleen, popliteal lymph node and cervical brown adipose tissue were increased. That means tumor-related immunosuppress and cachexia were markedly inhibited by SYM treatment as compared with tumor-bearing mice. On the other hand, Tamoxifen showed marked cytotoxic effects against MCF-7 and MCF-10A, decreases of tumor volume and weights, and increases of apoptotic tumor cells and related decreases of tumor cell volumes, but tamoxifen markedly deteriorated the tumor-related immune-suppress and cachexia. Conclusions: The results obtained in this study suggest that SYM showed favorable anticancer effects and anticachexic effects on the MCF-7 cell xenograft through immunomodulatory effects. SYM did not induce any cytotoxic effects against both normal and cancer cells.

  • To determine if body weight change is directly related to altered leptin and neuropeptide Y (NPY) gene expression, we assessed adipose tissue weight, percent body fat, leptin and NPY mRNA levels and serum leptin concentration in pigs at weights of 1, 20, 40, 60, and 90 kg. The results indicated that the weight of adipose tissues and the percent body fat of pigs significantly increased and correlated with body weight (BW) from 1 to 90 kg (p<0.01). Serum leptin concentrations and leptin mRNA levels in omental adipose tissue (OAT) increased from 1 to 60 kg, and then decreased from 60 to 90 kg. At 60 kg, the serum leptin concentration and leptin mRNA level significantly increased by 33.5% (p<0.01) and 98.2% (p<0.01), respectively, as compared with the levels at 1 kg. At 60 kg, the amount of leptin mRNA in subcutaneous adipose tissue (SAT) was significantly higher than that of 1 and 40 kg animals (p<0.05). NPY gene expression in the hypothalamus also changed with BW and at 60 kg the NPY mRNA level significantly decreased by 54.0% (p< 0.05) as compared with that in 1 kg. Leptin mRNA in OAT was correlated with serum leptin concentrations (r = 0.98, p<0.01), body weight (r = 0.82, p<0.05) and percent body fat (r = 0.81, p<0.05). This is the first report of the developmental expression of leptin in porcine OAT, peritoneal adipose tissue (PAT) and SAT, and proves that the expression of leptin in OAT could reflect the levels of circulating leptin. These results provide some information for nutritional manipulation of leptin secretion which could lead to practical methods of controlling appetite and growth in farm animals, thereby regulating and improving efficiency of lean meat production and meat production quality.

  • An 8-month-old, intact male Maltese dog was referred to us because of anorexia, diarrhea, and jaundice. Hematologic examination revealed immune-mediated hemolytic anemia, and abdominal ultrasonography revealed heterogeneous changes in mesenteric fat and coarse echotexture in the splenic parenchyma. Septic peritonitis was diagnosed on the basis of a bacterial culture test of the peritoneal fluid. Exploratory laparotomy and subsequent omental biopsy and splenectomy were performed. On histopathological examination, the omental mass and splenic lesions were diagnosed as grain foreign body granulomas. This report describes a rare case in which a grain foreign body was embedded in the spleen of a dog.

  • Obesity is consistently increasing in prevalence and can trigger insulin resistance and type 2 diabetes. Many lines of evidence have shown that macrophages play a major role in inflammation associated with obesity. This study was conducted to determine metformin, a widely prescribed drug for type 2 diabetes, would regulate inflammation through down-regulation of scavenger receptors in macrophages from obesity-induced type 2 diabetes. RAW 264.7 cells and peritoneal macrophages were stimulated with LPS to induce inflammation, and C57BL/6N mice were fed a high-fat diet to generate obesity-induced type 2 diabetes mice. Metformin reduced the production of NO, $PGE_2$ and pro-inflammatory cytokines ($IL-1{\beta}$, IL-6 and $TNF-{\alpha}$) through down-regulation of $NF-{\kappa}B$ translocation in macrophages in a dose-dependent manner. On the other hand, the protein expressions of anti-inflammatory cytokines, IL-4 and IL-10, were enhanced or maintained by metformin. Also, metformin suppressed secretion of $TNF-{\alpha}$ and reduced the protein and mRNA expression of $TNF-{\alpha}$ in obese mice as well as in macrophages. The expression of scavenger receptors, CD36 and SR-A, were attenuated by metformin in macrophages and obese mice. These results suggest that metformin may attenuate inflammatory responses by suppressing the production of $TNF-{\alpha}$ and the expressions of scavenger receptors.

  • The object of this study was to observe anticancer and related immunomodulatory and anticachexic effects of Insamyangyoung-tang aqueous extracts (ISYYTe) on non-small cell lung carcinoma (squamous epithelial carcinoma), NCI-H520, xenograft Balb/c nu-nu nude mice. Changes on the tumor volume and weights, lymphatic organ(spleen and popliteal lymph node), serum interferon (IFN)-${\gamma}$ levels, splenocytes and peritoneal macrophage activities (NK cell activity), splenic tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-$1{\beta}$ and IL-10 contents, splenic T-lymphocyte subsets (CD3+, CD4+ and CD8+) and TNF-${\alpha}+$ cells were observed with tumor mass and lymphatic organ histopathology to detect anticancer and immunomodulatory effects. In addition, changes on the body weights, epididymal fat weights and serum IL-6 levels were also detected with the thicknesses of deposited cervical brown adipose tissue and their mean diameters to monitor the tumor-related anticachexic effects. The results obtained in this study suggest that over 50 mg/kg of ISYYTe showed favorable anticancer effects on the NCI-H520 cell xenograft with immunomodulatory and anticachexic effects. However, detail mechanism studies should be conducted in future with the screening of the biological active compounds in this herb.

  • The aim of this study was to evaluate the antitumor activities of Typhae pollen (TP) by confirming in vitro cytotoxicity and in vivo anti-tumor and immune-modulatory effect with anti-cachexia effect. The MTT assay is used in HepG2 cell to detect potential cytotoxic activities of aqueous extract of Typhae pollen (TPe). After HepG2 tumor cell implantation, eight mice per groups were assigned to six groups. Three different dosages of TPe (500, 250 and 125 mg/kg) were orally administered in the amount of $10m{\ell}/kg$ and sorafenib also administered 20mg/kg, every day for 35 days from 28 days after the tumor cell implantation. We observed the changes on body weights, tumor volume and weights, lymphatic organ, serum interferon $(IFN)-{\gamma}$ levels, splenocytes and peritoneal NK cell activity, splenic tumor necrosis factor $(TNF)-{\alpha}$, interleukin $(IL)-1{\beta}$, IL-10 contents. Periovarian fat weights, serum IL-6 levels, thicknesses of deposited periovarian adipose tissue and mean diameters were also detected to monitor the tumor-related anticachexic effects. In tumor masses, the immunoreactivities of cleaved caspase-3 and cleaved poly (ADP-ribose) polymerase (cleaved PARP) - apoptotic marks, cyclooxygenase-2 (COX-2), inducible nitric oxide synthases (iNOS) and tumor necrosis factor $(TNF)-{\alpha}$ were additionally observed by immunohistochemistry. The results were compared with sorafenib. Decreases of COX-2 were demonstrated in sorafenib and TPe treated mice and also increases of iNOS in tumor masses were observed in TPe, not in sorafenib. TPe increased periovarian fat pad weights compared with tumor-bearing controls and sorafenib treated mice. TPe showed increases of splenic $TNF-{\alpha}$, IL-10 and $IL-1{\beta}$, serum $IFN-{\gamma}$ and NK cell activities corresponding to increases of spleen weights, lymph node weights and non-atrophic changes of lymph nodes. Our results show oral treatment of TPe 500, 250 and 125 mg/kg has potent in vitro and in vivo antitumor activities through modest cytotoxic effects, immunomodulatory effects and apoptotic activities in HepG2 tumor cells. In addition, TPe can prevent cancer related cachexia.
