  • An inflammatory myofibroblastic tumor (IMT) is a rare disease entity reported to arise in various organs. It is thought to be a neoplastic or reactive inflammatory condition, controversially. The treatment of choice for myofibroblastic tumor is surgery, and recurrence is known to be rare. The optimal treatment method is not well-known for patients ineligible for surgery. We report a 47-year-old patient with aggressive recurrent IMT of the lungs. The patient had been admitted for an evaluation of back-pain two years after a complete resection of pulmonary IMT. Radiation therapy was performed for multiple bone recurrences, and the symptoms were improved. However the patient presented again with aggravated back-pain six months later. High-dose steroid and non-steroidal anti-inflammatory drugs were administered, but the disease progressed aggressively, resulting in spinal cord compression and metastasis to intra-abdominal organs. This is a very rare case of aggressively recurrent pulmonary IMT with multi-organ metastasis.

  • Thymolipoma is rare benign tumor of the thymic gland and mostly occurs at anterior mediastinum. Thymolipoma comprises 2~9% of thymic tumor and less than 1% of mediastinal mass. Therefore, thymolipoma should be differentiated from anterior mediastinal tumor such as thymoma, germ cell tumor and lymphoma. These tumors resemble cardiomegaly, pleural effusion, basal atelectasis, pericardial tumor and cyst, pleural tumor, lung cancer and pulmonary sequestration, and differentiated from above mentioned diseases. Though most cases are asymptomatic, there can be dyspnea with compression of adjacent organ by mass effect, and myasthenia gravis. We experienced a thymolipoma simulating cardiomegaly and report the case with the review of literatures.

  • Inflammatory pseudotumor (IPT) is a rare benign tumor of unknown etiology that can occur in almost any organ system. It has neoplastic features such as local recurrence, invasive growth, and vascular invasion, leading to the possibility of malignant sarcomatous changes. The clinical presentations of colonic IPT may include abdominal pain, anemia, a palpable mass, and intestinal obstruction. A few cases of colonic IPT have been reported, but colonic IPT with pedunculated morphology is very rare. Furthermore, since it can mimic malignant polyps, understanding the endoscopic findings of colonic IPT is important for proper treatment. Herein, we present a case of colonic IPT with pseudosarcomatous changes, presenting as a large polyp, mimicking a malignant polyp in the cecum, along with a literature review.

  • The light-organ symbiont of pine cone fish, Vibrio fischeri, senses its presence in the host and responds to environmental changes by differentially expressing its symbiosis-related luminescence genes. The V. fischeri luminescence genes are activated by LuxR protein in the presence of an autoinducer. In an effort to elucidate the mechanism of regulation of luxR, a plasmid containing luxR was mutagenized in vitro with hydroxylamine and a luxR mutant plasmid was isolated by its ability to activate luminescence genes cloned in E. coli in the absence of the autoinducer. The specific base change identified by DNA sequencing was only single base transition at +78 from the transcriptional start of luxR. Based on a Western immunoblot analysis, the nucleotide change directed the synthesis of much higher level of LuxR protein without any amino acid substitutions. The results suggest that the region including the +78th base is presumably internal operator required for autorepression of luxR, and the increased cellular level of LuxR results in activation of luminescence genes by autoinducer independent fashion.

  • A 14-year-old, 7.4 kg, neutered male mongrel dog presented with vomiting, anorexia, and hematuria starting 3 days prior to admission. Serum biochemical profiles indicated severe azotemia. Computed tomography revealed loss of normal left kidney structure. The organ was 1.5 to 2 times larger than the right kidney with mixed attenuation. Histopathologic examination was performed after nephrectomy. The renal mass and mesenteric membrane were positive for vimentin and stained blue with Masson's trichrome. In conclusion, this was a rare occurrence of primary renal fibrosarcoma, most likely originated from the renal capsule, with local invasion into the mesenteric membrane.

  • Gut dysbiosis is one of prominent features in inflammatory bowel diseases (IBDs) which are of an unknown etiology. Although the cause-and-effect relationship between IBD and gut dysbiosis remains to be elucidated, one area of research has focused on the management of IBD by modulating and correcting gut dysbiosis. The use of antibiotics, probiotics either with or without prebiotics, and fecal microbiota transplantation from healthy donors are representative methods for modulating the intestinal microbiota ecosystem. The gut microbiota is not a simple assembly of bacteria, fungi, and viruses, but a complex organ-like community system composed of numerous kinds of microorganisms. Thus, studies on specific changes in the gut microbiota depending on which treatment option is applied are very limited. Here, we review previous studies on microbial modulation as a therapeutic option for IBD and its significance in the pathogenesis of IBD.

  • Patient-specific image-based internal dosimetry involves using the patient's individual anatomy and spatial distribution of radioactivity over time to obtain an absorbed dose calculation. Individual absorbed dose was calculated by accumulated activity multiply S-value of each organs. The aim of this study was to calculate the S-values using Monte Carlo simulation in monkey and mouse and evaluation of absorbed dose in each organ. Self-irradiation S-value of monkey heart self-irradiation was 3.15E-03 mGy-g/MBq-s, lung self-irradiation was 8.94E-04 mGy-g/MBq-s and liver self-irradiation S-value was 2.23E-03 mGy-g/MBq-s. Mouse heart self-irradiation S-value was 1.95E-01 mGy-g/MBq-s, lung was 9.59E-02 mGy-g/MBq-s, and liver was 1.40E-03 mGy-g/MBq-s. The results of this study show that the calculation protocol of image based individual absorbed dose of each organ using Monte Carlo simulation. Therefore, this study may be applied to calculate human specific absorbed dose.

  • We examined the effect of dietary Turkish propolis and flavomycin on growth performance, carcass characteristics, internal organ weights and some serum variables in quail (Coturnix coturnix japonica) birds. One hundred and fifty day-old quails were randomly divided into five groups, with ten replicate pens per treatment and three birds per pen. One group received the basal diet (antibiotic-free), the control. The flavomycin at 10 mg/kg diet and propolis at 0.5, 1 and 1.5 g/kg diet were added to the basal diet. Body weight gain, feed consumption and feed efficiency were determinated weekly. Carcass characteristics, internal organ weights and serum variables were determinated at the end of the study (35 day). The results showed that body weight gain, feed efficiency and carcass weight were improved significantly (p<0.01) when compared to control group for birds fed diets containing propolis and flavomycin between 14 to 35 days. The addition of 1 g/kg propolis to the diet resulted in significantly (p<0.01) better-feed efficiency as compared to control and other treatment groups. There were no significant differences in carcass yield, abdominal fat, liver gizzard, proventriculus and intestinal weight and intestinal pH among the groups. In addition, serum ALP, total protein, uric acid, cholesterol and triglyceride were not influenced by the any supplementation. However, birds fed with propolis tended to have higher serum HDL and lower level than birds fed the control diet. In conclusion, supplementation of propolis and flavomycin during the growth period showed similar effects on growth performance in quail. Therefore, it can serve as a natiral substitute for antibiotics in poultry diets.

  • Objectives: The purpose of this study was to investigate anti-obesity effect of Scutellariae Radix extract combined with metformin. Methods: Male C57BL/6 mice, 4 weeks of age, were used to set high-fat diet induced obesity model. They were grouped NOR (normal control), HFD (high fat diet control), MET (metformin, 100 mg/kg/day), MH2 (metformin 50 mg/kg/day+Scutellariae Radix 200 mg/kg/day), and HG4 (Scutellariae Radix 400 mg/kg/day). MET, MH2, and HG4 were orally administered for 10 weeks. Body weight was measured every week. Fasting blood glucose, triglyceride, total cholesterol (TC), high density lipoprotein, glutamic oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) were measured before sacrifice. Oral glucose tolerance test (OGTT) was also performed. Organ weight and internal fat weight were measured after sacrifice. Results: MH2 group showed a reduction of body weight when compared with HFD group. MH2 group showed stable blood level control which was calculated areas under the curves by OGTT. TC, GOT, GPT level, internal fat, and organ weight in MH2 group reduced. Conclusions: The combined treatment of Scutellariae Radix and Metformin has impact on treating obesity. Further studies are needed to evaluate the effect of Metformin and herbal medicine combination therapy.

  • The aqua-acupuncture blended with liquid medicine and acupuncture is known to be effective in treating various medical disorders. This study used gallbladders of bear (WoongDam, WD, Ursus arctos Linne) and pig(JeoDam, JD, Sus scrofa domestica Brisson) plus the stones from the ox gallbladder(WooHwang, WH, Bos taurus var, domesticus Gmelin) to produce the liquid medicine. For the acupuncture, acupoint of ST -36 which is located one finger breadth from the anterior crest of the tibia was selected. There were a couple of purposes in this experiment. First, the relationship between aqua-acupuncture and gastric activity was scrutinized. Secondly, the possibility of pig gallbladder as an alternative organ to bear gallbladder for making liquid medicine was evaluated. Thirdly, different injection concentration ratio of liquid medicine was tried to figure out the optimal dosage for the aqua-acupuncture. The data of the present results indicated that the mixtures of WD + WH and JD + WH have a similar hypotonic effect on the stomach. These findings illustrated that aqua-acupuncture or hydroacupuncture showed inhibitory effect on the stomach in addition to its well-known prophylactic value. Also the possible alternative medical organ of pig gallbladder was checked out since two mixtures illustrated very similar trends in suppressing the gastric activity. The injection concentration ratio was not very different between two mixtures in terms of gastric motility except a couple of ratio. In conclusion, the aqua-acupuncture is a promising way to control the gastric activity for better medical purposes and the gallbladder of pig was assessed as a prospective one for making a liquid medicine.
