A 12-year-old spayed female mixed-bred dog presented with nasal bleeding of 2 days duration and a skin nodule in the left flank. No abnormalities were found in coagulation profiles and blood pressure. Cytological evaluation of the nodule revealed numerous characteristic round organisms having a nucleus and a bar within macrophages and in the background, consistent with leishmaniasis. In vitro culture was unsuccessful but PCR of the nodular aspirate identified the organisms as Leishmania infantum, and the final diagnosis was canine leishmaniasis. No history of travel to endemic countries was noted. Because the dog had received a blood transfusion 2 years before the illness, serological screening tests were performed in all donor dogs of the commercial blood bank using the commercial Leishmania ELISA test kit, and there were no positive results. Additional 113 dogs with hyperglobulinemia from Seoul were also screened with the same kits but no positive results were obtained. To the best of the author's knowledge this is the first autochthonous case of canine leishmaniasis in Korea.

Fifty-two wether lambs weighing 30 kg were randomly assigned to 5 treatment groups; 1) initial slaughter. 2) control-maintenance (CON-MT), 3) control-ad libitum (CON-AL), 4) cimaterol-maintenance (CIM-MT) and 5) cimaterol-ad libitum (CIM-AL). Ad libitum-fed animals had free access of a high-concentrate diet, whereas maintenance animals were restricted in feed intake to maintain the initial weight of 30 kg for 90 days. Cimaterol was administered in the feed at 10 mg/kg. Regardless of feeding level, the administration of CIM improved carcass weight (p < .05), dressing % (p < .01), longissimus muscle area (p < .01), leg conformation and muscling (p < .01), USDA yield and quality grades (p < .01) and protein concentration (p < .01) in carcass as well as in muscle. Cimaterol feeding decreased organ wt (p < .01), baekfat depth (p < .01), intramuscular fat and overall fatness. Cimaterol was effective for muscle accretion even under restricted feeding condition. The greater accretion of muscle was the result of the hypertrophy of both type I and type II muscle fibers but the hypertrophy of type II fiber (110%) was much greater than that of type I fiber (37%). Cimaterol feeding decreased muscle DNA concentrations but the number of nuclei per muscle fiber was not changed, indicating that the lower DNA concentration was due to the dilution effect caused by the hypertrophy of muscle fiber. As evidenced by lower flank streaking, lower marbling and darker muscle, CIM feeding adversely affected meat quality. Meat tenderness was also adversely affected, resulting in significantly (p H .01) tougher meat in CIM-fed animals.

Background After skin tumor excision on the face, extremities, or trunk, the choice of treatment for a skin defect is highly variable. Many surgeons prefer to use a local flap rather than a skin graft or free flap for small- or moderately-sized circular defects. We have used unilateral or bilateral V-Y advancement flaps, especially on the face. Here we evaluated the functional and aesthetic results of this technique. Methods All of the patients were pathologically diagnosed with squamous cell carcinoma (SCC), basal cell carcinoma (BCC), or malignant melanoma or premalignant lesion (Bowen's disease). Thirty-two patients underwent V-Y advancement flap repair (11 unilateral and 21 bilateral) from January 2007 to June 2011. We analyzed the patients' age and satisfaction, and location and size of defect. The patients were followed up for 6 months or more. Results There were 22 women and 10 men. The ages ranged from 47 to 93 years with a mean age of 66 years. The causes were SCC in 15 cases, BCC in 13 cases, malignant melanoma in 1 case, Bowen's disease in 2 cases, and another cause in 1 case. The tumor locations were the face in 28 patients, and the scalp, upper limb, and flank each in one patient. All of the flaps survived and the aesthetic results were good. Postoperative recovery was usually rapid, and no complication or tumor recurrence was observed. Conclusions The V-Y advancement flap is often used not only for facial circular defects but also for defects of the trunk and extremities. Its advantages are less scarring and superior aesthetic results as compared with other local flap methods, because of less scarification of adjacent tissue and because it is an easy surgical technique.

This study was performed to make fundamental data of ultrasonographic diagnosis for liver and duodenum disease in native Korean cattle. Ultrasonographic appearance of liver, caudal vena cava, portal vein, gall bladdr and duodenum according to the growth were determined from 6 to 13 months by monthly examinations in 9 native Korean cattle. The caudal vena cava was determined at 11th intercostal space by use of ultrasonography. The portal vein and gallbladder were determined at 10th intercostal space by use oof ultrasonography. The liver were determined at 12, 11 and 10 th intercostal space by use of ultrasonography. The liver, caudal vena cava, portal cein, gallbladder and duodenum were examinde in standing position. Ultrasonograms were obtainde with 3.5 or 5.0-MHz convex and 5.0-MHz sector transducer. The diameter of vena cava at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 18.4, 20.6, 22.4, 25.1, 26.9, 27.3, 28.5 and 29.4 mm, respectively. The diameter of portal vein at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 19.5, 20.6, 22.3, 24.5, 26.9, 28.1, 30.7 and 31.5 mm, respectively. The diameter of gall bladder at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 63.2, 72.2, 75.1, 78.6, 80.5, 82.3, 84.4 and 91.1 mm, respectively. Cranial part of duodenum was identified near gall bladder by moving of hyperechoic ingesta. Descending duodenum paralleled with vertebrae is seen in the right upper flank and was adjacent to the abdominal wall, and was enveloped in the hyperechoic greater omentum, differentiating it from the jejunum and ileum. The diameter of cranial duodenum at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 23.3, 27.9, 29.9, 32.2, 34.4, 34.5, 35.1 and 36.5 mm, respectively. The diameter of descending duodenum revealed smaller diameter than that of cranial duodenum. Calculi in gallbladder were observed by ultrasonography.

The extruder type is classified as screw type and non-screw type in terms of the extrusion method. The screw type extruder, which is the most frequently used, is classified as the single screw extruder and the multi-screw extruder. They are classified as vertical type and horizontal type in terms of structure; and those for compounding and for forming in terms of function. The single screw extruder is a universal extruder, most of which is suitable for the extrusion forming of thermoplastic resin. The multi-screw(two-screw, three-screw and four-screw) extruder can increase the extrusion power using the engagement of the screw flank. The single screw extruder does not have a good mixing ratio of the raw material and stable extrusion power, while it has low construction cost and operation cost. In this study, the single screw extruder, which has many weak points compared with the multi-screw extruder, was studied. There have been many studies on the single screw extruder, and they led to its significant development. The existing study method, however, had complex analysis processes and required much time. In this study, the CFD was applied to the performance test and analysis of the extruder, and the optimal design condition of the extrusion power for the screw and die of the single screw extruder was found by comparing the analysis results with the actual performance measurement of the single screw extruder.

Objective : In vitro proapoptotic effect of Hangbaek-Tang (HBT) has been documented by one of us. In the present study, we aimed to demonstrate in vivo effect of HBT on tumor growth. Methods : In vitro selective cytotoxicity of HBT was examined by enumeration of viable cell numbers using BC3A mouse leukemic cells and normal spleen cells. In vivo effect of HBT (25 and 50 mg/mouse) on tumor growth was assayed using BC3A cells innoculated subcutaneously in the flank. Annexin-V apoptosis assay and PI staining was performed to determine the effective serum factor in HBT-treated mice. Leukocyte recruitment into peritoneum were analyzed by microscopy with a stained cytosmear of peritoneal lavage fluid. Results : HBT exhibited in vitro selective cytotoxicity to leukemic cells and did not show any toxicity on immune organs. In vivo i.p. administration of HBT induced significant reduction in tumor growth but not complete regression. Sera obtained from HBT-treated mice strongly inhibited BC3A cell growth in vitro and were revealed to markedly enhance apoptosis and accompanying cell death, when compared to those from PBS-treated mice. Abundant extravasation of leukocytes, especially neutrophils, into peritoneum was observed in HBT-treated mice. Conclusions : HBT causes leukemic, BC3A cell death in vivo via apoptosis as well as in vitro, for which functional involvement of leukocytes is suggested.
