This study was attempted to know that the interactions of various fungi, and methionine and MgSO4 introduced as the substrate of culture media for fungi were affected to produce aflatoxins by Asp. flavus. 5 different fungi were isolated from the fermented soybean mash and were cultured in Chemically Defined medium (C.D. media) and soybean mash at 25 degrees for 10 days. (1) It was confirmed that Asp. flavus produced aflatoxins in the C.D. medium and soybean mash, but that Asp. niger, Asp. oryzae, Asp. awamori and Asp. terreus did not produced them respectively. (2) Asp. flavus cultured with Asp. niger did not produce aflatoxins in C.D. medium, but produced in soybean mash, in other hand, Asp. flavus with other fungi except Asp. niger produced aflatoxins in C.D. medium and soybean mash. (3) The growth of fungi were more prosperous in the separate culture than in the mixed culture. (4) In the C.D. medium added 20% of cultured medium of Asp. niger, Asp. flavus did not produce aflatoxins but other cultured medium did not prohibit the production of aflatoxins by Asp. flavus. (5) On the contrary, MgSO4 increasing the productivity of aflatoxins by Asp. flavus in the C.D. medium methionine known as one of precurser of aflatoxins did not affected the increasing productivity with significance.

OBJECTIVE: To compare the safety and efficacy of intravaginal misoprostol versus oral dinoprostone for labor induction at term. METHODS: One hundred of patients at term were randomized to receive either 50microgram of misoprostol vaginally every 4 hours or dinoprostone 0.5mg orally every 1 hour for the maximum of six doses. Intravenous infusion of oxytocin was administered under such circumferences as the patient did not go into active labor after maximum dose, SROM was developed without an adequate contraction pattern, or the patient had arrest of dilatation(no change in cervical dilatation for 2 hours). We compared the frequency of oxytocin augmentation, administration to delivery interval, vaginal delivery rate within 12 hours and 24 hours, intrapartum complications, induction failure, mode of delivery, neonatal outcomes, and maternal complications between two groups. RESULTS: The average interval from administration to delivery was shorter in the misoprostol group(739.4+/-372.4min vs 1087.7+/-765.1min, p<0.05), but the interval from administration to vaginal delivery of each group was similar(724.3+/-375.4min vs 800.3+/-697.0min). Regarding the frequency of vaginal delivery within 24 hours, however, misoprostol group was higher than dinoprostone group(88% vs 56%, p<0.001). And oxytocin augmentation of labor occurred less commonly in misoprostol group than in dinoprostone group(20% vs 76%, p<0.05). Any statistically significant difference in intrapartum complications, mode of delivery, and neonatal or maternal adverse outcome was not appeared between these two group. CONCLUSION: Vaginal misoprostol is as effective and safe as oral dinoprostone for cervical ripening and induction of labor at term. In addition, vaginal misoprostol contributes the curtailment of labor induction expenditure due to its moderate price; misoprostol costs 100 won per 50microgram.

PURPOSE: To determine the CT findings which distinguish consolidation-type bronchioloalveolar carcinoma fromnecrotizing pneumonia. MATERIALS AND METHOD: This study involved ten patients with pathologically-provenconsolidation-type bronchioloalveolar carcinoma and 34 with necrotizing pneumonia proven pathologically either inthe laboratory or clinically. We retrospectively analyzed CT features including the enhancement pattern ofconsolidated lung, the presence and internal density of cavity within consolidated lung, CT angiogram sign,air-bronchogram, pleural enhancement, pleural effusion, and change in extrapleural tissue and its density. RESULT: CT findings in patients with necrotizing pneumonia showed higher attenuation in marginal (94.1%) and inner(85.3%) portions in consolidated lung than in muscles (p<0.005); the presence of cavity (91.2%, p<0.05) ; cavitywith fluid or air-fluid level (77.4%, p<0.005); pleural enhancement (88.2%, p<0.00003) ; pleural effusion (33.3%,p<0.05); and change in extrapleural tissue (64.7%, p<0.05). CT findings in patients with consolidation-typebronchioloalveolar carcinoma showed lower attenuation in marginal (90.0%) and inner (60.0%) portions ofconsolidated lung than muscles (p<0.005) and of cavity containing air (100%; p<0.005). However, air-bronchogramand CT angiogram signs were not helpful in differentiating the two groups. CONCLUSION: CT can help differentiateconsolidation-type bronchioloalveolar carcinoma and necrotizing pneumonia.

In northern China, annual epidemics of acute-onset flaccid paralysis diagnosed clinically Guillain-Barre syndrome have been observed for at least 20 years. These patients had a distinctive pattern that shares clinical and cerebrospinal fluid findings with demyelinating Guillain-Barr syndrome. But it was different from Guillain-Barr syndrome physiologically and pathologically. Electrodiagnostic studies showed normal motor distal latencies and limb conduction velocity, but reduced compound muscle action potential amplitude. When sensory nerve action potentials are elicitable, F waves are within the range of normal. This disorder was named acute motor axonal neuropathy characterized pathologically by motor nerve fiber degeneration of variable severity and by sparing of sensory fibers. Recovery is usually complete. We experienced a case of acute axonal motor neuropathy, and reported the case with a review of literature.

Leigh Disease, or subacute necrotizing encephalopathy (SNE), is a degenerative disorder characterized by lesions of the gray and white matter in the bran and spinal cord. The pathogenesis was known as mitochondrial enzyme defect of the respiratory chain system. We experienced 2 cases of Leigh disease. The first case, a seven-month old girl who was presented with weak respiration and failure to thrive, showed lactic acidemia and increased lactic acid in CSF fluid, high signal intensity in the bilateral putamen and head of caudate of nucleus at T2 weighted MR imaging. The second case, a 3-year-old girl with ataxic gait and bilateral ptosis also showed lactic acidemia, increased lactic acid in CSF fluid and high signal intensity in the bilateral basal ganglia. Respiratory difficuly developed in both cases and died within 1 month after visiting our hospital. The diagnosis was made by lactic acidosis and specific MRI finding. We report these cases with a brief review of its related literature.

BACKGROUND: In reporting results of case-control studies, odds ratios are useful methods of reporting findings. However, odds ratios are often misinterpreted in the literature and by general readers. METHODS: We searched all original articles which were published in the Korean Journal of Family Medicine from 1980 to May 2011 and identified those that report "odds ratios." Misinterpretation of odds ratios as relative risks has been identified. Estimated risk ratios were calculated when possible and compared with odds ratios. RESULTS: One hundred and twenty-eight articles using odds ratios were identified. Among those, 122 articles were analyzed for the frequency of misinterpretation of odds ratios as relative risks. Twenty-two reports out of these 122 articles misinterpreted odds ratios as relative risks. The percentage of misinterpreting reports decreased over years. Seventy-seven reports were analyzed to compare the estimated risk ratios with odds ratios. In most of these articles, odds ratios were greater than estimated risk ratios, 60% of which had larger than 20% standardized differences. CONCLUSION: In reports published in the Korean Journal of Family Medicine, odds ratios are frequently used. They were misinterpreted in part of the reports, although decreasing trends over years were observed.

Adenofibromas of the uterine cervix, which are classified as benign tumors of mixed epithelium and mesenchymal cells, are extremely rare. Most common symptom is usually abnormal genital bleeding. It is very difficult to diagnose preoperatively. Recommended method of treatment is total hysterectomy, because it usually recurs. We experienced a case of adenofibroma of the uterine cervix with increased CA125, so report it with a review of the literature.
