BACKGROUND AND OBJECTIVES: Perfluorocarbon exposed sonicated dextrose albumin (PESDA) microbubbles has been suggested to facilitate thrombus disruption under the transcutaneous ultrasound (US). Thus, we investigated whether such a noninvasive approach could augment thrombolytic effect of fibrinolytic agent in an experimental thrombotic model. MATERIALS AND METHODS: Thrombus formation was induced with electrical injury in the rabbit iliofemoral arteries (n=20): Thrombus occlusion was documented by angiography in all arteries. In the control group, only tissue plasminogen activator (t-PA, 3 mg/kg) was administered intrav-enously in five rabbits. In the Group 1 (n=9), injured arteries were exposed to transcutaneous US (20 kHz, 30 W/cm2, continuous mode) with t-PA (3 mg/kg). In the Group 2 (n=6), the same treatment was given while administering PESDA continuously (10 ml/min, intravenous). Angiographic results were evaluated at 10 minute interval for 1 hour respectively. RESULTS: In the control group, two of five iliofemoral arteries (40.0%) were recanalized and one of nine iliofemoral arteries (11.1%) was recanalized in Group 1. In contrast, four of six iliofemoral arteries (66.7%) were recanalized angiographically in Group 2 (p=0.392 vs. control group: p=0.047 vs. Group 1). However, late reocclusion occurred in all iliofemoral arteries of Group 2. CONCLUSION: Although PESDA with transcutaneous US significantly enhanced initial angiographic patency rate of t-PA, it was associated with high rate of reocclusion. Further studies will be necessary for clinical application of this noninvasive method in acute arterial occlusion.

The possible complications after parotidectomy are facial nerve palsy, Frey's syndrome, sialocele, salivary fistula, hematoma infection, and flap necrosis. Postoperative sialocele and salivary fistula are relatively uncommon and the management varies. We experienced a rare postoperative complication of excessive and prolonged drainage of saliva after superficial parotidectomy and removal of an necessary parotid gland tumor. The patient could be treated successfully with conservative management such as compressive dressing, restriction of oral intake of irritant food, maintenance of oral hygiene and the use of amitriptyline(antidepressant).

Cystadenomas are benign neoplasm in which the epithelium demonstrates adenomatous proliferation. Several morphologic variants of cystadenomas have bean described, including papillary-oncocytic, mucous, and seromucous subtypes. Cystadenomas arising from salivary glands are very rare and seromucous cystadenoma of parotid gland has not been reported in Korea so far. Cystadenomas of the parotid gland usually Present as asymptomatic slowly growing mass and those of the minor salivary glands produce smooth nodules that may be compressible. We performed a superficial parotidectomy in a patient with a seromucous cystadenoma. This may be the first report of seromucous cystadenoma of carotid gland in Korea.

To clarify the role of stem cells in hepatocarcinogenesis, CD44 expression was investigated in mouse livers as well as embryonic cell lineages treated with diethylnitrosamine (DEN). Liver tumors induced by DEN were analyzed by immunohistochemisty for CD44. Liver tissues were sampled at 6, 24, and 48 hr after treatment with saline or DEN. Mouse embryonic stem cells (ESCs), hepatic progenitor cells (HPCs), and hepatocyte like cells (HCs), representing 0, 22, and 40 days of differentiation, respectively, were treated with DEN at four doses (0, 1, 5, and 15 mM, respectively) for 24 hr, after which CD44 expression levels were examined by relative quantitative real-time PCR. CD44 expression was weakly detected in tumor cells as well as in some hepatocytes surrounding the tumor cells. However, CD44 expression was not detected in liver tissue treated with DEN at early time points. The CD44 mRNA expression level was significantly different among cells treated with 5 mM DEN at day 22 (P<0.01) as well as 1, 5, and 15 mM DEN at day 40 (P<0.01) compared with control. Taken together, CD44 expression slightly increased in mouse DEN-induced tumors. Furthermore, expression of CD44 in embryonic cell lineages treated with various doses of DEN significantly differed among embryo stem cells and derived hepatic lineage cells. This suggests that CD44 expression may be modulated in the progeny of stem cells during their differentiation toward hepatocytes, and its expression may increase in the tumor stage but not during early carcinogenesis.

The PMT-air airplane crash accident occurred in June 25, 2007 in Sihanoukville, Cambodia. All 22 passengers and crew, including 13 Korean victims, were found dead. Human identification was done at the Cambodian-Russian Soviet friendship hospital. All of Korean victims were identified with fingerprint comparison, age estimation, comparison of belongings and examination of past medical history. In this identification process, the examination of antemortem data source with searching personal blog of internet had been proved efficient in human identification. The antemortem data collection with internet access may be useful and should be combined with classical antemortem data collection process because it is beyond spatial and time limitation.

This study was conducted to identify the demand of work-site health promotion program of employees. A self-administered questionnaire method was uses to collect data from 492 employees from 40 work-sites in Taegu City and Kyungpook Provincial area. The work-site health screening programs conducted for several years were placed low value by employees. The out-door exercise was the most popular heath promotion activity implemented at work-site as a whole. The employees expressed that periodic health check-up, the health counseling, indoor exercise would be implemented as a health promotion program in the future. The male employees regarded that the periodic health check-up program should be established preferentially at work-site. However, the female employees gave priority to fitness program. The health related behavioral patterns slightly influenced the preference of health promotion program. The health screening program for employees should be improved and the health education of nutrition and diet for female employees should be implemented.

BACKGROUND AND OBJECTIVES: The Korean Organ Transplant Registry (KOTRY), which was the first national transplant registry in Korea, was founded by the Korean Society for Transplantation and the Korean Center for Disease Control in 2014. Here, we present the initial report of the Korean Heart Transplant Registry. METHODS: A total of 183 heart transplantation (HTPL) patients performed at 4 nationally representative hospitals were collected from April 2014 to December 2015. We analyzed donor and recipient characteristics, treatment patterns, and immediate post-transplantation outcomes. RESULTS: One hundred and eighty-three patients were enrolled. The mean age of the patients was 50.5±13.5 years. The mean age of the male recipients was 4 years greater than that of the female recipients (51.7±13.3 years vs. 47.9±13.7 years, p < 0.050). The mean age of donors was more than 12 years younger than that of heart recipients (37.6±10.1 years). Dilated cardiomyopathy was the predominant cause (69%) of heart failure in recipients, followed by ischemic heart diseases (14%) and valvular heart disease (4%). Rejection episodes were most frequent in the 1–6-month period after transplantation (48%), and rarely required intensive treatment. Infection episodes were most frequent <1 month after transplantation (66%) and bacterial and viral infections were equally reported. The 1-year survival rate was 91.6% and most mortality cases occurred during the perioperative period within 1 month after transplantation. CONCLUSION: With the establishment of the KOTRY in 2014, it is now possible to present nationwide epidemiological data for HTPL in Korea for the first time. The KOTRY is the first national HTPL registry in Korea, and will continue until 2023.
