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.

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.

We report a case of immature teratoma arising at the suprasellar region in a 18 year-old-male who presented with bitemporal hemianopsia, nausea and polydipsia. The teratoma is a rare neoplasm consisting of 0.5% to 1.2% of all intracranial tumors. The clinical presentation, radiologic finding, pathology and treatment are briefly described with a review of other cases from the literature in view of clinical features and management.

BACKGROUND: The p53 and retinoblastoma(Rb) tumor suppressor genes are associated with the pathogenesis of several types of human cancer. Substantial. proportion of the primary lung cancers or cell lines have been reported to have the p53 and/or the Rb gene mutations. But so far there is no report on the analysis of the Rb gene polymorphism as one of the genetic susceptibility marker. This study was undertaken to establish the gene frequencies of the polymorphic genotypes of the p53 and Rb genes in Koreans to evaluate the possible involvement of these genotypes as a risk factor of lung cancer. METHODS: In this study 145 controls without previous and present tumor history and 128 lung cancer patients were subjected to analysis The two intragenic polymorphisms of the p53 gene(exon 4/AccII, intron 6/MspI) and one intron 17/XbaI polymorphism of the Rb gene were analysed by the method of polymersae chain react lion-restriction fragment length polymorphisms(PCR-RFLPS). The genotype of the intron 3/16 bp repeat polymorphism of p53 was determined by PCR and direct gel electrophoresis. RESULTS: There were no significant differences in the genotype distributions of the p53 gene between lung cart cert patients and controls. But heterozygotes(Arg/Pro) of the exon 4/AcclII polymorphisms were slightly over-represented than controls, especially in the Kreyberg type I cancer, which was known 13 be associated with smoking. The intron 3/16 bp duplication and the intron 6/MspI polymorphisms were in complete linkage disequilibrium. About 95% of the individuals were homozygotes of the common alleles both in the 16 duplication and MspI polymorphisms, and no differences were deteced in the genotype distributions between lung cancer patients and controls. Overall genotype distributions of the Rb gene polymorphisms between lung cancer patients and controls were not significantly different However, the genotype distributions in the Kreyberg type I cancer were significantly different from those of controls(p=0.0297) or adenocarcinomas(p=0.0008). It was noticeable that 73.4% of the patients with adenocarcinomas were heterozygotes(r1/r2) whereas 39.2% of the Kreyberg type I cancer were heterozygous at this polymorphisms. In the lung cancer patients, significant differences were a]so noted between the high dose smokers and low dose smokers including non-smokers(p=0.0258). The relative risk to Kreyberg type I cancer was significantly reduced in the individuals with the genotype of r1/r2(odds ratio=0.46, 95%C.I.=0.25-0.86, p=0.0124). The combined genotype distribution of the exon 4/AccII of the p53 and the intron 17 Rb gene polymorphisms in Kreyberg type I cancers were significantly different from dose of controls or adenocarcinomas. The highest odds ratio were observed in the individuals with the genotypes of Arg/pro and r2/r2(odds ratio=1.97, 95%C.I.=0.84-4.59) and lowest one was in the patients with Arg/Arg, r1/r2 genotype(odds ratio=0.54, 95%C.I.=0.25-1.14). CONCLUSION: The p53 and the Rb gene polymorphisms modulate the risk of smoking induced lung cancer development in Koreans. However, the exact mechanism of risk modulation by these polymorphism remains to be determined. For more discrete clarification of associations between specific genotypes and lung cancer risk, the evaluations of these polymorphisms in other ethnics and more number of patients will be needed.
