  • 지방종은 지방조직에 기인하는 경계가 명확한 간엽종양인데 일반적으로 작고, 증상이 없으며, 흔히 경부에 위치한다. 그러나 지방종이 드물게 종격동에서 발견되는데, 지방종이 종격동 안에서 커지게 되면, 간혹 신경혈관구조물을 압박할 수 있다. 신경 압박으로 인한 호너 증후군이 유발된 58세 남자의 경부-종격동 지방종을 보고한다. 환자는 우측 흉곽입구를 관통한 모래시계 형태의 경부-종격동 지방종으로 우측 경부가 부어있고, 우측 안검 하수와 후측부 불편감을 호소하였다. 종괴를 제거한 후 신경 압박으로 유발된 호너 증후군의 증상이 바로 소실되었다.

  • A parosteal lipoma is a benign tumor containing mature adipose tissue and is intimately related to the adjacent periosteum. We experienced a very rare case of parosteal lipoma arising from the shaft of femur. A 46 years old lady visited the hospital with complaining of slowly growing mass in her thigh for 7 month. Initially, it was difficult to differentiate from osteochondroma, parosteal osteosarcoma or liposarcoma. Based on the assessment of plain radiogram and magnetic resonance imaging, it was suspected the parosteal lipoma or osteosarcoma. Marginal excision was performed, and it was confirmed to parosteal lipoma histologically. We present the case with review of literatures.

  • This study was to examine expression of the recombinant full-length adiponectin (recombinant adiponectin) in insect ovarian cell culture system and to characterize structural properties of the recombinant adiponectin secreted in medium. Gene construct encoding the recombinant adiponectin contained N-terminal collagen-like domain (110 Amino Acids, AAs), C-terminal globular domain (137 AAs) and C-terminal peptides for detection with V5 antibody (26 AAs included adaptor peptide) and purification using the 6xHis tag (6 AAs). The approximate molecular weight of the product (monomer) was 35 kDa. Molecular mass species of the expressed recombinant adiponectin were monomer (~35 kDa), dimer (~70 kDa), trimer (~105 kDa) and hexamer (~210 kDa). The major secreted species were the LMW forms, such as monomer, dimer, and trimer. There was MMW of hexamer as minor form. HMW multimers (~300 kDa) were shown as a tracer or not detected on the SDS-PAGE in several experiments (data not shown). The multimer forms in this study were not compatible to those in animal or human serum and adipose tissue by other researcher's study in which the major multimer forms were HMW. By protein denaturing experiments with reducing reagent (${\beta}$-MeOH), anionic detergent (SDS) and heat ($95^{\circ}C$) on the SDS-PAGE, not all adiponectin multimers seemed to have disulfide bond linked structure to form multimers. The recombinant adiponectin which expressed in insect ovarian cell culture system seemed to have the limitation as full physiological regulator for the application to animal and human study.

  • Obesity has been considered as an important risk factor for the development of colorectal cancer (CRC), but the association has not been fully elucidated. Obesity is linked significantly to adipose tissue dysfunction and to alteration of adipokines in blood; in particular, obesity-induced inflammation is thought to be an important link between obesity and colorectal cancer. Based on epidemiological studies, we undertook a systematic review to understand the association of circulating levels of selected adipokines, including adiponectin, leptin, resistin, IL-6 and TNF-${\alpha}$, with the level of CRC risk. Most prospective studies suggested protective effects of adiponectin, but these were attenuated by body mass index (BMI) and waist circumference (WC) data in our meta-analysis. On the other hand, meta-analyses for leptin and CRC did not demonstrate any association, similar to the results of systematic review. Although it proved difficult to determine whether other selected adipokines (resistin, IL-6 and TNF-${\alpha}$) were related to CRC risk due to small number of reports, the present systematic review suggested a positive association with elevated resistin levels but null associations with IL-6 and TNF-${\alpha}$.

  • This study was conducted to investigate the effect of dietary soluble fiber administration and/or high fat diet on serum and brain neurohormonal profiles, adipose tissue mass and body weight gain in Sprague-Dawley rats. Four groups of rats were respectively fed 10% fat diet (C), 10% fat plus pectin diet (P), 20% fat diet (HFC) and 20% fat plus pectin diet (HFP) for 4 weeks. In HFP group, the food and energy intake, body weight gain, FER including fecal excretion were the smallest (p<0.05). Serum HDL-cholesterol, triglyceride and glucose level were also the lowest in HFP group (p<0.05). The weight of brain, epididymal fat pad and adrenal gland except liver didn't show any significant differences among groups. Interestingly serum norepinephrine concentration of HFP group tended to be higher, but dopamine concentration tended to be lower than those of HFC group. However serum catecholamine concentration didn't show any significant differences among all groups. Norepinephrine and epinephrine contents of right portion of midbrain of P and HFP groups were remarkably lower than those of the C group. These results suggested that soluble fiber pectin consumption might affect neurohormonal profiles in serum and brain according to dietary fat level.

  • Leptin, a 16-kDa cytokine, is secreted by adipose tissue in response to the surplus of fat store. Thereby, the brain is informed about the body's energy status. In the hypothalamus, leptin triggers specific neuronal subpopulations (e.g., POMC and NPY neurons) and activates several intracellular signaling events, including the JAK/STAT, MAPK, PI3K, and mTOR pathway, which eventually translates into decreased food intake and increased energy expenditure. Leptin signal is inhibited by a feedback inhibitory pathway mediated by SOCS3. PTP1B involves another inhibitory pathway of leptin. Leptin potently promotes fat mass loss and body weight reduction in lean subjects. However, it is not widely used in the clinical field because of leptin resistance, which is a common feature of obesity characterized by hyperleptinemia and the failure of exogenous leptin administration to provide therapeutic benefit in rodents and humans. The potential mechanisms of leptin resistance include the following: 1) increases in circulating leptin-binding proteins, 2) reduced transport of leptin across the blood-brain barrier, 3) decreased leptin receptor-B (LRB), and/or 4) the provocation of processes that diminish cellular leptin signaling (inflammation, endoplasmic reticulum stress, feedback inhibition, etc.). Thus, interference of the cellular mechanisms that attenuate leptin signaling improves leptin action in cells and animal models, suggesting the potential utility of these processes as points of therapeutic intervention. Various experimental trials and compounds that improve leptin resistance are introduced in this paper.

  • Obesity is a growing health problem that many countries face, mostly due to the consumption of a Westernized diet. In this present study we observed the effects of a soybean extract fermented by Bacillus subtilis MORI (BTD-1) containing 1-deoxynojirimycin against high fat diet-induced obesity. The results obtained from this study indicated that BTD-1 reduced body weight, regulated hepatic lipid content and adipose tissue, and also affected liver antioxidant enzymes and glucose metabolism. These results suggest that administration of BTD-1 affects obesity by inhibiting hyperglycemia and free radical-mediated stress; it also reduces lipid accumulation. Therefore, BTD-1 may be potentially useful for the prevention of obesity and its related secondary complications.

  • This report described a severe bilateral microphthalmia in a young Holstein calf. The anomalous calf with wry tail showed normal vigor, appetite and normal body weight except for eye defect. The orbits were shallower and smaller than normal. The orbit bilaterally contained a white small mass suspected as eyeball. A spot-like remnant of eyeball (REB) was buried in the mixture of vestigial extraocular muscles and adipose tissue of the bilateral orbit. Histologically, the REB was composed of irregularly arranged elements of ocular wall such as sclera, retina and ciliary body. But any destructive changes in the central nervous systems were not detected. This case of eye defect was defined as severe bilateral microphthalmia. The cause of this ocular defect is unknown.

  • Arctii Fructus (AF), which contains arctigenin (ARC) as a major constituent, is traditionally used as an anti-inflammatory medicine to treat inflammatory sore throat. Although several studies have proven its anti-inflammatory effects, there have been no reports on its use in inflammation related disorders such as obesity, cancer metastasis, and allergic responses. This study investigated the anti-obesity effect and anti-metastasis effect of AF and ARC. AF and ARC inhibited weight gain by reducing the mass of white adipose tissue in high fat diet (HFD)-induced obese mice. Serum cholesterol levels were also improved by AF and ARC. In in vitro experiments, AF and ARC decreased differentiation of white adipocytes. Furthermore, AF induced differentiation of brown adipocytes, which are able to consume surplus energy through non-shivering thermogenesis. Also, AF and ARC inhibited colon cancer and lung metastasis of colon cancer. They suppressed not only colorectal cancer cell progression by inhibiting cell growth, but also prohibited lung metastasis by regulating epithelial-mesenchymal transition (EMT), migration, and the invasion. These effects were confirmed in an experimental metastasis mouse model. In addition, AF and ARC inhibited mast cell mediated allergic responses. Collectively, our study suggests that AF and ARC might show inhibitory effects on inflammation related diseases, including obesity, cancer, cancer metastasis, and allergic responses.

  • Purpose: Body mass index (BMI) is often used to predict surgical difficulty in patients receiving total knee arthroplasty (TKA); however, BMI neglects variation in the central versus peripheral distribution of adipose tissue. We sought to examine whether anthropometric factors, rather than BMI alone, may serve as a more effective indication of surgical difficulty in TKA. Materials and Methods: We prospectively enrolled 67 patients undergoing primary TKA. Correlation coefficients were used to evaluate the associations of tourniquet time, a surrogate of surgical difficulty, with BMI, pre- and intraoperative anthropometric measurements, and radiographic knee alignment. Similarly, Knee Injury and Osteoarthritis Outcome Score (KOOS) was compared to BMI. Results: Tourniquet time was significantly associated with preoperative inferior knee circumference (p=0.025) and ankle circumference (p=0.003) as well as the intraoperative depth of incision at the quadriceps (p=0.014). BMI was not significantly associated with tourniquet time or any of the radiographic parameters or KOOS scores. Conclusions: Inferior knee circumference, ankle circumference, and depth of incision at the quadriceps (measures of peripheral obesity) are likely better predictors of surgical difficulty than BMI. Further study of alternative surgical indicators should investigate patients that may be deterred from TKA for high BMI, despite relatively low peripheral obesity.
