Renal IV DSA was applied to evaluate 15 potential renal donors and 14 examinations of 12 renal allograftrecipients,. We evaluate the angiographic acute or chronic rejection, alteration of renal size aftertransplantation, excretion time of the contrst media and pre, post DSA serum creatinine level. DSA is a safe,easily performed, out patient procedure and useful in evaluation and indistinguishing status surgical anastomosis,intrarenal vasculatures, arterial excertion time and rejection phenomenon.

DSA was done in 133 examinations of 128 patients during 2 years consist of 9 examination of IV DSA and 124examination of selective cardiac DSA after cardiac catheterization. Open heart surgery was performed in 90patients and 12 patients showed discrepancy between pre-and post operative diagnosis, showing a total 86.7% ofdiagnostic accuracy with DSA. We experienced the significant reduction in dose of contrast media, 30-40% of doseof conventional cardiac heart disease. DSA is an accurate simple and safe method in evaluation of cardiac disases.

BACKGROUND: Patients experience significant differences in aspects of mortality, quality of life, and costs between during the year of receiving liver transplant (LT) and the subsequent years (post-LT). This study aimed to estimate the medical utilization and cost of LT for patients compared to post-LT patients by using a recent National Patient Sample (NPS) data provided by the Korean Health Insurance Review and Assessment Service (HIRA). METHODS: This study used a subset of the 2015 HIRA-NPS. Patient claims data that included Z944 (Korean Standard Classification of Diseases code for LT status) were selected. Within the selected data, LT patients were identified based on whether the national health insurance number code of Q80 (procedure code for LT surgery) was included, and they were compared to post-LT patients. RESULTS: In the analysis, 330 patients were included. The average cost per patient was 90,066±36,959 thousand KRW and 10,557±9,668 thousand KRW for LT and post-LT patients, respectively. Especially, LT patients' costs for injection/procedure, surgery/treatment, and examination were higher than other costs, being 35,983±18,115 thousand KRW, 28,246±9,408 thousand KRW, and 12,131±6,604 thousand KRW, respectively. For inpatients, the average number of hospitalized days was 63.5±66.0 days for LT patients and 22.3±35.1 days for post-LT patients. CONCLUSION: Compared to post-LT patients, LT patients had higher costs, especially for injection/procedure, surgery/treatment, and examination. Additionally, the LT group had longer hospitalization duration and higher costs for their hospital admission, whereas they did not show a significant difference in number of visits and medical costs for outpatient-care.

Objective To study the antibacterial constituents of Senecio cannabifolius.Methods The antibacterial effect of all the extracts was tested in vitro with Staphylococcus aureus,Bacillus subtilis(Gram-positive bacilli),and Escherichia coli(Gram-negative bacillus).Chemical constituents were isolated by chromatography.Physicochemical characters and spectroscopic analyses were employed for their structural identification.Results Five compounds were isolated and their structures were elucidated by chemical and spectral methods as follows: methyl-5-hydroxy-2-pyridinecarboxylate(E-13),6-hydroxy-7,7a-dihydro-2(6H)-benzofuranone(E-14),2-(1,4-dihydroxycyclohexanyl)-acetic acid(E-16),3-hydroxycyclohexanecarboxylic acid(E-17),and 4-hydroxy benzaldehyde(B-14).Conclusion All of them are isolated from the plants of Senecio L.for the first time.

A case of malignant epithelial mesothelioma of the peritoneum diagnosed by fine needle aspiration cytology is described. The smear showed many individually scattered or clustered large round malignant epithelial cells intermingled with relatively small nonneoplastic mesothelial and mesenchymal cells. Papillary configurations with thick fibrous core were also seen. The malignant cells were virtually reminiscent of reactive mesothelial cells but they were larger in size and had more prominent nucleoli and more frequent binucleated or multinucleated cell formations than reactive mesothelial cells. The characteristic features of malignant cell of mesothelioma compared with the metastatic adenocarcinoma were relatively uniform cellular size, prominent round nucleoli, large round vesicular nuclei with finely granular chromatin pattern, smooth nuclear membrane, abundant glassy cytoplasm rather than bubbly mucin-containing cytoplasm and fuzzy cell border.

PURPOSE AND BACKGROUND: Recently several clinical studies suggested that maternal treatment with magnesium sulfate had protective effects against cerebral palsy in premature infants. But previous studies with differing perinatal animal models resulted in inconclusive results with regard to magnesium neuroprotection. Our purpose was to study the neuroprotective effect of magnesium sulfate and optimal dosage on hypoxicischemic brain damage in the newborn rat. METHOD: Seven-day-old rats(n=68) underwent right carotid ligation, followed by 3 hours of hypoxia(8% oxygen in 92% nitrogen). Rats received magnesium sulfate immediately before and again after hypoxia(two doses, 150mg-600mg/kg/dose, n=39), or saline solution(n=29). Severity of injury was assessed 5 days later, by visual evaluation of ipsilateral hemisphere infarction and by measurement of bilateral hemispheric cross sectional areas. RESULTS: Magnesium sulfate pre-treatment reduced the incidence of liquefactive cerebral infarction and atrophy from 80.8% in controls to 22.2% with magnesium sulfate(450 mg/kg/dose, P<0.05). Quantitation of hemispheric areas confirmed these findings. Percent protection based on inter-hemisphere area differences by pre-treatment with magnesium sulfate 450mg/kg/dose ranged from 71.1%(hippocampus) to 90.8%(striatum). However higher dose of magnesium(600mg/kg/dose) did not attenuate hypoxic-ischemic brain injury in the newborn rat but increased mortality. CONCLUSION: Pretreatment of magnesium sulfate has neuroprotective effects against hypoxia-ischemia in the newborn rat and adequate dose of magnesium sufate is important to protect the brain. Magnesium pretreatment may be an effective strategy to decrease the severity of neonatal hypoxic-ischemic brain injury in the adequate dose.

PURPOSE: To study the MR findings to predict the site of dural attachment in meningiomas. MATERIALS AND METHODS: We retrospectively reviewed MR findings of 23 patients with surgically confirmed meningiomas and analysed the characteristics of dural attachment site of meningiomas and tumor growing vector against dura. RESULTS: In the 10 cases that tumor had a single dural base, the dural base was tumor bed. in the 2 cases that tumor had more than two dural bases, wider, irregular and thicker enhancing dura was tumor bed. In the 7 of the 11 cases of diffuse dural bases with tumor, we could predict tumor bed considering the degree of compression to the brain parenchyma and the tumor growing vector. CONCLUSIONS: In the case of tumor having more than two surfaces contacting the dura or with narrow attachment site, it is possible to predict the site of dural attachment if we consider the characteristrics of dural attachment site and tumor growing vector against dura.
