PURPOSE: To implant tissue chips in New Zealand rabbits, and thus redurce the frequency with which scattered VX2 carcinoma nodules and early metastasis develop in these animals. MATERIALS AND METHODS: VX2-carcinoma tissue chips of two different sizes were implanted under ultrasonographic guidance. In each of 12 New Zealand rabbits (group 1), there 1-mm tissue chips were implanted in the liver using an 18-gauge needle, and in the same way, one 3-mm chip with an added gelfoam pellet was implanted in the proximal lumen of the liver of each of ten other New Zealand rabbits (group 2). Three weeks after implantation, the animals underwent dvalphase CT scanning and were sacrificed, and the Number and size of tumor nodules, and metastasis were evaluated either macro-or microscopically. RESULTS: In ten rabbits in group I, a total of 21 nodules (16 in the liver, 5 in the peritoneal wall) were observed, which in nine rabbits in group 2, a total of ten nodules-all in the liver-were present. CT scans depicted tumor nodules in 50% of group-I rabbits, and in 29% those in group 2. Mean tumor diameter was 12 +/-9 mm in group 1 and 6.4 +/-3 mm in group 2. Histologic examination indicated the presence of nodular VX2 carcinoma, with varying degrees of central necrosis, a feature more prominent in group 2. CONCLUSION: To provide a well-localized tumor nodule in rabbit liver, tissue chip implantation of VX2 carcinoma, especially with added gelfoam, is a good alternative to intraparenchymal injection of tumor suspension.

BACKGROUND: This study was designed to evaluate the safety and the efficacy of fosinopril(Monopril(R)) in the treatment of mild to moderate essential hypertension. METHOD: Fosinopril(10mg) once a day was administrated as a starting dose in 20 patients with essential hypertension in the morning and a one step upward titration was performed(fosinopril 20mg once a day, after 4 weeks treatment). RESULT: After 2 weeks treatment with dose of 10mg, the systolic blood pressure(SBP) was decreased(183.8+/-28.5 vs, 161.5+/-25.9mmHg, p<0.05) and the diastolic blood pressure(DBP) was also decreased significantly(108.3+/-9.3 vs, 96.6+/-10.3mmHg, p<0.05). The effect of fosinopril were maintained. The SBP an DBP were decreased in 14 out of 20 patients till 8 weeks. There was no significant change in heart rate before and after fosinopril treatment(74.3+/-10 vs, 76.4+/-7.9beats/min). Fosinopril had no significant effects on laboratory findings such as serum creatinin, BUN, AST/ALT, WBC, Platelet and lipid profiles. Mild dry coughing was noticed only in 5 patients and it did not disturb continuing medication. CONCLUSION: Fosinopril is an effective antihypertensive agent, as monotherapy once a day in patients with mild to moderate hypertension.

The first case of human cryptosporidiosis was reported in Korea in 1995; however, an outbreak of Cryptosporidium has not been reported in Korea until now. This paper describes the first outbreak of cryptosporidiosis in Korea. On May 24, 2012, a local public health center filed a report on 126 residents with gastrointestinal symptoms in an old apartment complex in Seoul. Epidemiological investigations were implemented on 125 of the 126 patients. The patients were reported continuously over a period of 22 days. Diarrhea was the most common clinical symptom, and lasted for 5 days on average. The tap water was the only common exposure of the patients. During the environmental investigation it was discovered that the water and septic tanks were situated closely and that the waste water pipes were corroded where they passed over the water pipes. Cryptosporidium parvum was detected in 3 of the 7 stool specimens by PCR-RFLP. A number of Cryptosporidium oocysts were also detected in the water specimens from the water tank. In conclusion, Cryptosporidium parvum was the key causal pathogen of this outbreak. It is presumed that the tap water was contaminated by a sewage leak from the aged pipelines.

BACKGROUND: Viral myocarditis is considered as a cause of dilated cardiomyopathy. At present, two pathogenic mechanisms may be involved in the pathogenesis of viral myocarditis and subsequent cardiomyopathy. First, the virus infection of myocyte may directly lead to either cell death or persistent metabolic dysfunction. Second, virus-induced immune or autoimmune mechanism may play a role. METHODS: To test the therapeutic efficacy of immunosuppression with cyclophophamide(CYP) on coxsackievirus B3(CB3) myocarditis, 10-14 week-old Balb/c mice were inoculated with 4000 plaque-forming units of CB3. In experiment 1, CYP (100mg/kg/day subcutaneous injection, s.c) was administrated daily on days 1-7(group 2, n=16). In experiment 2, CYP 30mg/kg/day s.c(group 3, n=32) or CYP 100mg/kg/day s.c(group 4, n=32) were administrated on days 8-14. The animals of infected controls(group 1, n=26) and group 2, 3, 4 were dissected at days 4, 7, 15, 22 and spleen, heart, thymus and body weights were measured. RESULTS: In experiment 1. survival rate in group 2 on day 7, 15 were low compared with group 1(85%, 0% vs 100%, p<0.05). and myocardial virus titers in group 2 on day 4 was 50 times, and on day 7, 1000 times higher compared with group 1, Histologically, on day 7, focal cellular infiltrations were prominent findings in group 1, but diffuse myocardial necrosis without cellular infiltration were observed in group 2. In experiment 2, survival rate, cardiac histopathology myocardial virus titer and serum neutralizing antibody titers did not differ among groups 1, 3 and 4. In experiment 1 and 2, the spleen-to-body-weight and thymus-to-body-weight ratios were significantly lower in CYP treated groups than those in controls and marked cellular depletions in spleens and thymus were observed in CYP treated groups. CONCLUSIONS: As the results of above, it can be concluded that the immunosuppression during viremic phase of murine viral myocarditis aggravated the myocardial necrosis, and during aviremic phase, the administration of CYP didnot affect the process of viral myocarditis. Thus, direct viral mechanisms in the production of cardiomyocyte injury in CB3-infected mice appear to bo more important than cell mediated immune mechanism. To understand relevant pathogenic mechanisms of clinical myocarditis and dilated cardiomyopathy resulting from viral infection, the experimental study expanding into nonmurine animals and into various models using other infectious agents may be required.

PURPOSE: The incidence of abdominal trauma with intra-abdominal organ injury or bowel rupture is increasing. Articles on the diagnosis, symptoms and treatment of small bowel perforation due to blunt trauma have been reported, but reports on the relationship of mortality and morbidity to clinical factors for prognosis are minimal. The purposes of this study are to evaluate the morbidity and mortality of patients with small bowel perforation after blunt abdominal trauma on the basis of clinical examinationand to analyze factors associated with the prognosisfor blunt abdominal trauma with small bowel perforation. METHODS: The clinical data on patients with small bowel perforation due to blunt trauma who underwent emergency surgery from January 1994 to December 2009 were retrospectively analyzed. The correlation of each prognostic factor to morbidity and mortality, and the relationship among prognostic factors were analyzed. RESULTS: A total of 83 patients met the inclusion criteria: The malewas 81.9% .The mean age was 45.6 years.The mean APACHE II score was 5.75.The mean time interval between injury and surgery was 395.9 minutes.The mean surgery time was 111.1 minutes. Forty seven patients had surgery for ileal perforations, and primary closure was done for 51patients. The mean admission period was 15.3 days, and the mean fasting time was 4.5 days. There were 6 deaths (7.2%), and 25 patientssuffered from complications. CONCLUSION: The patient's age and the APACHE II score on admission were important prognostic factors that effecteda patient's progress. Especially, this study shows that the APACHE II score had effect on the operation time, admission period, the treatment period, the fasting time, the mortality rate, and the complication rate.
