We evaluated the clinical effects of Nicorandil in 27 patients (17 male and 10 female) with ischemic heart disease (17 patients of stable effort angina, 3 patients of unstable effort angina, 6 patients of spontaneous angina, 1 patient of variant angina) in terms of the effect on the anginal pain, electrocardiographic changes and side effects. The results obtained were as follows; 1. The pulse rate was not changed by the drug administration and blood pressure were decreased slightly by Nicorandil in a daily dose of 15 mg divided into 3 dose, but these decrease were not significant in statistical meaning. 2. Improvement in EKG changes was observed in 9 patients (69%) among the 13 patients who showed abnormal EKG initially. 3. Anti-anginal effect of nicorandil were excellent in 14 patients, good in 8 patients, fair in 3 patients and so the rate of global improvement was 82%. 4. Nicorandil had side effects in 7 patients, headache (4 patients), palpitation, ocular pain, edema, but these were transitory and tolerable except of one case who could not be continued because of severe headache.

Many drugs can result in a variety of pathologic reactions in the lung, especially the cytotoxic drugs. Amongcytotoxic drugs bleomycin is a prototype. Bleomycin-related pulmonary toxicity is usually known as dose-dependent and can be enhanced with concurrent oxygen therapy, irradiation, or other chemotherapeutic agents. The incidence of bleomycin-induced pulmonary toxicity has been reported as varying from 2 to 46%, and 1% of fatal lung disease. We describe the radiographic and HRCT findings of bleomycin-related pulmonary toxicity developed in two patients: one in ovarian teratocarcinoma, the other malignant lymphoma patient. Chest radiographs and HRCT of these patients showed ground-glass opacities, consolidation, linear and reticular opacities, and interlobular septal thickening. These abnormalities were bilateral, and symmetrical and were found predominantly in the area of mid-and lower-lung zone.

In recent years, digital technology has been developed in dentistry, which denture frameworks can be manufactured using DMLS (Direct Metal Laser Sintering) technique. A traditional impression method can be replaced by oral scanning and wax pattern production process can be achieved by the use of CAD/CAM techniques. The designed STL files can be sent to DMLS devices to fabricate final components of removable partial dentures (RPD). The advantages of digital dentistry are concision and precision. In this case study, a fracture of occlusal rests providing support and indirect retention was repaired by DMLS and laser welding techniques. It shows satisfactory results in adaptation accuracy and functional properties of the repaired denture.

BACKGROUND: Little Is known about the compared efficiency of different third generation enzyme-linked immunosorbent assays (ELISA) fort the detection of anti-HCV. We examine the relative sensitivity and specificity of three third-generation anti-HCV assays, and results of discrepant samples among the anti-HCV ELISA are compared with data of a third-generation recombinant immunoblot assay and reverse transcription polymerase chain reaction (RT-PCR) . METHODS:A total of 167 samples (61 positive and 106 negative), screened by a second-generation IMx(R) anti-HCV assay (Abbott 2.0; Abbott Laboratories, USA), weve tested with Innotest HCV 3.0(R) (Green Cross, Korea), LG HCD 3.0(R) (LG, Korea) and DONG-A HCV 3.0(R) (Dong-4, Korea). The discrepant specimens among the 4 anti-HCV ELISA were tested by LG HCD Confirm(R) (LG, Korea) and RT-PCR. RESULTS: The concordance rates of all 4 ansi-HCV ELISA were 80.2% (134/167) and 92.2% (154/167), respectively. The 28 and 31 of 33 specimens showing discrepancy among 4 anti-HCV ELISA were tested with LG HCD Confirm and RT-PCR, respectively. Serum HCV RNA was positive in 2 of 2 reactive and in 6 of 26 nonreactive on LG HCD Confirm. The sensitivity, specificity, positive predictive value, negative predictive value and concordance rate of 4 anti-HCV ELISA were 97.7%, 85.2%, 70.0%, 99.0% and 88.5% (Abbott 2.0) ; 81.4%, 96.7%, 89.7%, 93.7% and 92 7% (Innotest 3.0), 81.4%, 98.4%, 94.6%, 93.8% and 93.9% (LG 3.0), 86.0%, 95.7%, 88.1%, 95.1% and 93.3% (DONG-A 3.0), respectively. CONCLUSIONS: These data indicate that the sensitivity and specificity of 3 third-generation anti-HCV ELISA are comparable, and that these reagents demonstrate improved specificity compared to the second-generation ELISA.

BACKGROUND: The relationship between viral hepatitis and lichen planus (LP) remains as a matter of controversy. Geographical variations are suggested to be a major factor influencing such association. Reliable figures from Korean patients are still lacking. OBJECTIVE: The aim of this study is to determine the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) infections in Korean patients with lichen planus (LP) and to compare it with patients without LP. METHODS: The retrospective study was performed on 45 LP patients and 45 controls with matching age and gender. We examined for serological evidences of hepatic disease, hepatitis B surface antigen (HBsAg), and anti-HCV seropositivity. Statistical analysis was calculated by using an unpaired t-test and Fisher's exact test. RESULTS: No significant differences between the serum levels of alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were observed between the two groups. The prevalence of HBsAg in LP patients (4.4%) was not significantly higher (p>0.05) than those of the control subjects (2.2%). None of the patients with LP nor the control subjects had Anti-HCV. CONCLUSION: Korean patients with LP did not have any significant associations with liver diseases or HBV, and HCV infections. Although a large-scale multicenter study is needed to support our results, it is not advisable for Korean patients with LP to be tested for liver functions or HBV, and HCV infections as part of a routine screening test.

We analyzed 54 cases of spontaneous intracerebral hematoma in the basal ganglia who had been admitted to Pusan National Hospital from June, 1991 to December, 1992 and underwent CT-guided stereotactic aspiration. Fifity four cases had basal ganglia hematoma with or without ventricular rupture. In 12 cases out of them, the residual hematoma could be completely evacuated by urokinase irrigation through a catheter introduced into the cavity of hematoma. Patients with preoperatively poor neurologic condition, large or deep-seated hematoma, or the operation undergone before 6 hours from ictus, had worse outcome. In the case whose hematoma was removed more than 60%, Glasgow Outome Scales were not changed significantly. Patients of spontaneous intracerebral hematoma mostly are older age, so careful observation and medical treatment are required to prevent postoperative complications and improve general condition.

Ganglionneuroblastoma is a rare neoplasm involving central nervous system. We have recently experienced a case of cervicothoracic extradural ganglionneuroblastoma invaded from upper posterior mediastinum. The patient presented with a progressive weakness of both lower extremities and had difficulty in voiding. The plain X-ray films, thoracic spine CT scan and myelography disclosed an extradural mass from C6 to T4 level. This extradural mass was communicated with upper posterior mediastinum. The mass was surgically removed and then the patient showed good recovery postoperatively.

PURPOSE: The purpose of this study was to assess the relative diagnostic capability of magnetic resonance angiography(MRA) and CT angiography(CTA) in the evaluation of intracranial aneurysm. MATERIALS AND METHODS: MRA and CTA were performed in 14 intracranial aneurysms (Including four which were ruptured) confirmed in the II patients involved by conventional angiography(CA). The size(in largest dimension) of the aneurysms ranged between 3 mm and 20 mm and the mean was 10.5 mm. For MRA, the 3D TOF method, with magnetization transfer suppression, wasused at 1.5T. For CTA, twenty seconds after beginning the injection of contrast media(100mL with use of a power injector at the rate of 3 mL/sec), CT scanning(30-second exposure and 60-mm length) was performed with a table speed of 2 mm/sec and a section thickness of 2mm. The resulting data were reformatted by MIP. MRA and CTA were compared with regard to the detection of aneurysms and their neck, size, shape, direction, intensity and relationship to adjacent bony structures or vessels. RESULTS: All aneurysms were clearly visualized with CTA. Inone case with a 3-mm aneurysm, however, this was not defined on MRA. Of the 13 aneurysms demonstrated by both MRA and CTA, eight were seen equally well with both modalities. CTA was considered to be superior to MRA in fivecases, either because calcification in the aneurysm wall was seen only on CTA(n = 3) or because the relationship with adjacent bony structures were seen better with CTA(n = 2). With CTA, the intensities of the aneurysm were homogeneous in all cases ; with MRA, however, the intensities of three large aneurysms were different. CONCLUSION: MRA and CTA may be useful in the evaluation of intracranial aneurysm, CTA has specific advantages over MRA inthe evaluation of large aneurysms, calcification of aneurysm wall and relationship with adjacent bony structure.
