  • This study was performed to examine the combined effects of L-carnitine and isoflavone supplementation on weight reduction and body fat distribution in overweight women. Overweight/obese women (body mass index > $23kg/m^2$) who were not diagnosed any type of diseases were included in this study and sixty subjects ($41.1{\pm}1.5$ years, $25.9{\pm}0.3kg/m^2)$ were randomly assigned to a placebo (n=30) or a supplement group (n=30, L-carnitine 300 mg+isoflavone 40 mg/day). We measured anthropometric parameters, abdominal fat distribution by computerizd tomography and blood components before and after the 12 week intervention period. After the 12 weeks of supplementation, subjects in L-carnitine and isoflavone supplement group showed a significant reduction of body weight (p < 0.001), body fat % (p < 0.05), and waist to hip ratio (p < 0.01) whereas placebo group did not show any changes. In a CT-scanned results, total fat area at L4 level was significantly reduced by 8.1% (p < 0.01) with the reduction of visceral fat area (-11.1%, p < 0.001) and subcutaneous fat area (-7.0%, p < 0.05) in the supplement group. The supplementation of L-carnitine and isoflavone showed the significant improvement of HDL-C (p < 0.01) and apoB (p < 0.05) concentrations, however, change values in those markers were not significant compared with those of the placebo group. In addition, a significant increase of adiponectin level (p<0.001) was observed in the supplement group after the intervention. The result of present study demonstrated that supplementation of 300 mg L-carnitine and 40 mg isoflavone per day fur 12 weeks can give beneficial effects on weight reduction and visceral fat accumulation. These potential antiobesity supplement can produce more favorable effects when combined with lifestyle modification.

  • Various forms of fermented soybean products are well documented for their health benefits. The efficacy of anti-obesogenic effect of Doenjang, one of the most commonly used seasonings in Korean cuisine, has been reported only in animal models; thus, an evaluation of Doenjang needs to be conducted in human studies. We aimed to test the hypothesis that Doenjang supplementation reduces body weight and changes body composition in overweight adults. A total of 51 overweight adults participated in this study. A group of males with BMI ${\geq}23kg/m^2$ and waist to hip ratio (WHR) ${\geq}$ 0.90, and a group of females with BMI ${\geq}23kg/m^2$ and WHR ${\geq}$ 0.85 were randomly assigned to either a Doenjang supplement (9.9 g dry/day) group or a placebo group for a 12-week randomized, double-blind and placebo-controlled study. Anthropometric parameters, abdominal fat distribution by computerized tomography (CT) and blood components were measured before and after the intervention period. After the 12-week study, the Doenjang supplementation group had significant reductions in body weight (kg), body fat mass (kg) and body fat (%) compared to the placebo group, the supplementation of Doenjang resulted in a significant reduction in visceral fat ($cm^2$), although no changes were observed in total and subcutaneous fat are as ($cm^2$), serum lipid profiles and dietary intakes. The present study demonstrated that daily supplementation of 9.9 g dry/day of Doenjang for 12 weeks reduces body weight and visceral fat in overweight adults.

  • Background: A pancreatic pseudocyst is one of various complications occurring in acute or chronic pancreatitis. It is usually located in the retroperitoneal space near the pancreas. However, other unusual locations are also possible. Jones initially described the mediastinal pseudocyst in 1940. Since then, fewer than 50 cases have been reported. A diagnosis of a mediastinal pseudocyst is accomplished by imaging studies revealing the cystic nature of the mass with evidences of acute or chronic pancreatitis. There is some controversy regarding the appropriate management of mediastinal pseudocyst because of the high mortality and morbidity after surgical management. Here we report a case of a mediastinal pancreatic pseudocyst found in a patient with asymptomatic alcohol-related pancreatitis complicated by the development of a mediastinal pseudocyst, which quickly resolved after endoscopic retrograde pancreatic and biliary drainage and subcutaneous injection of a somatostatin analog(octreotide acetate) without any complications.

  • Various calcium phosphate bioceramics are distinguished by their excellent biocompatibility and osteoconductivity. Especially, the exceptional biodegradability of $\beta$-TCP makes it a bone graft substitute of choice in many clinical applications. The activation of osteoclasts, differentiated from macrophage precursor cells, trigger a cell-mediated resorption mechanism that renders $\beta$-TCP biodegradable. Based on this evidence, we studied the biodegradation process of granular-type $\beta$-TCP bone graft substitute through in vitro and in vivo studies. Raw 264.7 cells treated with RANKL and M-CSF differentiated into osteoclasts with macrophage-like properties, as observed with TRAP stain. These osteoclasts were cultured with $\beta$-TCP nano powders synthesized by microwave-assisted process. We confirmed the phagocytosis of osteoclasts by observing $\beta$-TCP particles in their phagosomes via electron microscopy. No damage to the osteoclasts during phagocytosis was observed, nor did the $\beta$-TCP powders show any sign of cytotoxicity. We also observed the histological changes in subcutaneous tissues of rats implanted with granule-type $\beta$-TCP synthesized by fibrous monolithic process. The $\beta$-TCP bone graft substitute was well surrounded with fibrous tissue, and 4 months after implantation, 60% of its mass had been biodegraded. Also, histological findings via H&E stain showed a higher level of infiltration of lymphocytes as well as macrophages around the granule-type $\beta$-TCP. From the results, we have concluded that macrophages play an important role in the biodegradation process of $\beta$-TCP bone graft substitutes.

  • Objectives : We investigated the effects of Herba Ephedrae and Rhizoma Amorphophalli on high fat diet induced obese male mice. Methods : 8 weeks old, high fat diet induced obese male mice were divided into 5 groups: C57BL/6 normal control, obese vehicle control, GGEx55 (Herba Ephedrae), GGEx61 (Rhizoma Amorphophalli), GGEx62 (Herba Ephedrae + Rhizoma Amorphophalli). After mice were treated with GGEx for 8 weeks, we measured body weight gain, food intake, feeding efficiency ratio, rectal temperature, fat weight, plasma leptin and lipid levels. We also took micro-computerized axial tomography (micro-CT) on the mice. Results : 1. GGEx55 and GGEx62 groups significantly decreased body weight gain and feeding efficiency ratio compared with vehicle control. But they significantly increased rectal temperature. 2. Plasma total cholesterol and LDL-cholesterol concentrations were significantly increased by GGEx55 groups, whereas were significantly decreased by GGEx62 groups compared with vehicle control. 3. GGEx55 and GGEx62 groups significantly decreased total, subcutaneous and visceral fat as well as fat areas in micro-CT analysis of abdomen compared with vehicle control. 4. Plasma GOT and GPT concentrations were significantly increased by GGEx55 groups compared with vehicle control. Conclusions : These results demonstrate that GGEx55 and GGEx62 effectively reduces body weight gain, feeding efficiency ratio in high fat diet induced obese mice, leading to the modulation of obesity. In addition, GGEx55 and GGEx62 decreases visceral adipose tissue mass and improves plasma lipids, suggesting that GGEx55 and GGEx62 may act as a therapeutic agent for obesity.

  • Two cell lines derived from spontaneous canine mammary gland tumors were established and characterized. Mammary gland tumors from 9 years old pug and 9 years old toy-poodle dogs were collected by aseptic surgical resection and primary culture was performed. The histopathologic examination of tumors revealed adenocarcinoma and complex carcinoma and two dogs died from metastasis of the tumors. The tumor cells were subcultured over 60 times for more than 1 year and morphological consistency maintained. Light microscopic examination, growth curve, doubling time calculation, xenotransplantation to female nude mice, immunohistochemistry for wide spectrum keratin, vimentin, $\alpha$-smooth muscle actin and cytokeratin 8 was performed for characterization. The cell lines exhibited polygonal, elongated cell shape and cytoplasmic bridge and doubling time of 47.1 hrs and 18.6 hrs, respectively. Subcutaneous xenotransplantation to nude mice of the cells produced localized palpable mass within 4 weeks in 4 of 5 and 5 of 5 nude mice, respectively. In immunohistochemical examination one cell line showed strong positive against wide spectrum keratin and cytokeratin 8 and the other cell line showed strong positive against smooth muscle actin and cytokeratin 8. Additional characterization would be possible by investigator's needs and the cell lines may be useful for in vivo and in vitro studies of canine mammary tumor and adjuvant therapies.

  • Objective.: Sparganosis locations in humans are usually presented with a subcutaneous tissue of abdominal wall, chest, abdominal vicera and brain, but are rarely found in the breast. Methods. A case of sparganosis was confirmed by surgical excision of two parasites in a 76-year-old female patient present to a palpable mass in the right breast (presumed to have been sparganosis approximately 3 years ago). She had no history to direct ingestion of snakes or frogs, but had the history of drinking contaminated water. Mammography, ultrasonography, MRI, and FDG PET/CT imaging findings for patient were characteristic of sparganosis due to suspicion of breast cancer. Conclusions: The first route of infection in humans is drinking contaminated water. The second route is the ingestion of raw or partially cooked snakes or frogs. The third route is infected wound snake, frog muscle that attach to the case. However, only a few cases of drinking contaminated water have been reported in the country. Ultrasonography, MRI is known to be helpful for diagnosis of breast sparganosis. However, Mammography, ultrasonography, MRI, and FDG PET/CT for breast sparganosis is not reported present in the country. Reported the case and reviewed the related literature briefly.

  • Caliper measurements of tumor volume have been widely used in the assessment of tumors in animal models. However, experiments based on caliper data have resulted in unreliable estimates of tumor growth, due to necrotic areas of tumor mass. To overcome this systematic bias, we engineered a new luciferase-expressing rat prostate cancer cell line (MLL-Luc) that produces bioluminescence from viable cancer cells. MLL-Luc cells showed a strong correlation between bioluminescence intensity and cell number ($R^2$=0.99) and also accurately quantified tumor growth, with reduced bioluminescence signals caused by necrotic cells in a subcutaneous MLL-Luc xenograft model. The accurate quantification of tumor growth with bioluminescence imaging (BLI) was confirmed by a better antitumor effect of combination chemotherapy, compared to that based on caliper measurements with a correlation between the bioluminescence signal and tumor volume ($R^2$=0.84). These data suggest that bioluminescent MLL xenografts are a powerful and quantitative tool for monitoring tumor growth and are useful in evaluating the efficacy of anticancer drugs, with less systematic bias.

  • The Korea Institute of Oriental White Stork Rehabilitation Research (KIOWSRR) is breeding oriental white storks for residential rehabilitation in South Korea. Three oriental white storks were referred with anorexia and depression. Two storks were died before examinations and one stork was died after 1 day of fluid therapy. On necropsy, salmon-colored subcutaneous and visceral fats were examined in all storks. Multiple focal necroses on liver surface were also examined. In gizzards, many gravels and grasses were severely tangled; therefore, it produced a large mass that blocked digestive system of the storks. Small intestinal segments of the stork, which was dead after the fluid therapy, were severely adhesive. On histopathology, diffuse necroses with/without inflammation were examined in the liver, gizzard and intestine in all storks. Bile stasis was additionally examined in the liver. According to the results of the examinations, all storks were diagnosed as gizzard impaction caused by parorexia.

  • Purpose: The goal of cancer surgery is complete removal of cancer tissue and prevention of recurrence. Surgeons can change the surgical instruments after total resection of the cancer mass. The purpose of this procedure is to prevent dissemination of the cancer cells attached to the surgical instruments. Authors hypothesize the possibility of local recurrence caused by the cancer cells attached to the surgical instruments in the skin cancer cases. Methods: Skin cancers were induced by using DMBA-TPA two-stage carcinogenesis model in 10 of Balb/c mice. In 2-weeks, skin cancer was developed in all 10 mice. cancer cell attached surgical instruments were made by pinching the removed cancer tissue using Adson tissue forcep 10, 20, 30 times each. To count number of cancer cells in each forcep with different number of pinching was done, the forceps were washed in 30 mL of the normal saline and Cytospin preparation was done. To make recurrence models from cancer cell attached surgical instrument, three incisions were made in normal skin of each mouse, and local seeding was done by pinching subcutaneous tissue in 10, 20, 30 times each by using Adson teeth forceps mentioned above as cancer cell attached surgical instrument. Results: All skin cancers were squamous cell carcinoma. Local recurrences were developed in 7 mice (3 in 10 times forceping site, 2 in 20 times forceping and 3 in 30 times forceping). In the cytospin test, the mean number of squamous cells in 100 microscope was 28.6 in 10 times, 47.2 in 20 times, 93.6 in 30 times, respectively. P value was 0.002 in Wilcoxon-Sign test. Conclusion: The number of cell count was significantly increased as number of pinching was increased. And these cells are able to induce local recurrence by local seeding. Considering this result, authors are able to confirm that the minimal handling in cancer surgery is important factor to prevent local recurrence.
