A clinical study was made on 189 cases of various types of arrhythmia diagnosed among 1,100 patients. Incidence of arrhythmia was 17.2% of the total cases (male 58.2%, female 41.8%). Of 189 cases of arrhythmias, 78(41.3%) had bundle branch block, 42(22.2%) atrial fibrillation, 18(9.5%) atrioventricular block, 15(8%) premature ventricular contraction, 6(3.2%) sinus arrhythmia, 6(3.2%) W.P.W. syndrome, 4(2%) premature atrial contraction, 3(1.6%) atrial flutter-fibrillation, 3(1.6%) ventricular bigeminy, 3(1.6%) intraventricular conduction defect, 2(1.1%) atrial flutter, 2(1.1%) nodal bigeminy, 2(1.1%) ventricular bigeminy, 1(0.5%) paroxysmal atrial contraction and 1(0.5%) A-V nodal rhythm, 1(0.5%) nodla premature contraction, 1(0.5%) paroxysmal atrial contraction and 1(0.5%) sinus arrest. Etiological diagnoses of patients with arrhythmia were rheumatic heart disease (21.7%), hypertensive heart disease (12.7%), arteriosclerotic heart disease (12.7%), thyrotoxic heart disease (1.6%), anemic heart disease(1.6%) congenital heart disease (2.6%), cerebral vascular accident (1.6%), essential hypertension (9%) cerebral arteriosclerosis (0.53%), cor pulmonale (2.1%). chronic myocarditis (1.6%), anemia (1.6%), chronic nephritis (1.6%), acute glomerulonephritis (0.53%) chronic hepatitis (1.1%), tuberculosis (4.2%), bronchiectasis (1.1%), leprosy (0.53%), epilepsy (0.53%) intoxication (2.6%) cardiac neurosis (11.6%) and unknown (8%). The cardinal symptoms consisted of palpitation, dyspnea, headache, edema, dizziness, cough, left chest pain. gastrointestinal complaints, chest discomfort (thightness), weakness and fatigability. The incidence of arrhythmia was highest in the 4 th decade.

This study was carried out to visualize lead by Timm sulphide silver method and to define lead-induced change of duodenal absorptive cells of rat after administration of 0.01% lead acetate with drinking water. Sprague-Dawley rats, weighing 250g, were used, and they were orally administered with 0.01% sodium acetate and sacrificed at 0.5, 1, 1.5 hours and 2, 7, 15, 30, 45, 60 days after administration. A portion of duodenal tissue was observed under light microscope, scanning and transmission electron microscopes after development with Danscher method. The blood lead concentration in experimental group began to increase from the 2nd day after administration, and it increased gradually until the 45th day and decreased at the 60th day. On light microscope, many brown lead granules were observed at the villi tip at the 2nd day. There is mild blunting of villi tip at the 45th day. At the 60th day, most of the villi were mildly shortened and showed lymphangiectasia. On scanning electron microscope, the villi tip was mildly blunted and the extrusion zone became irregular at the 45th day. The depth of creases did not change. At the 60th day, the villi tip was moderately blunted and the extrusion zone was markedly irregular. The depth of creases increased. On transmission electron microscope, at 0.5 hour after oral administration, numerous lead granules were diffusely scattered and were not confined to any specific microorganelles. The lead granules decreased with time. At the 7th 15th day, the intercellular spaces were widened and several vacuoles appeared and the condensation of mitochondrial matrix. There was also ribosomal detachment from RER, and there was neither secondary lysosomes or post-lysosomes. At the 30th and 45th day, secondary lysosomes appeared and the condensation of mitochondrial matrix with early formation of myelin figures was noted. At the 60th day, the intercellular space widening extended to the upper most portion of the cells, and nonspeciqic degenerative changes became severe. In view of above mentioned findings, it can be concluded that passive diffusion as well as active transport was partly involved in the absorption of lead. Most of the changes of microorganelle are compatible with nonspecific degenerative changes which could occur due to impairment of oxidative phosphorylation.

Finger print patterns were studied in a series of 99 male schizophrenics who met with the diagnostic criterias of International Pilot Study of schizophrenia except items associated with chronicity in exclusion criteria, As controls, the autbors used 400 Korean men who were free of congenital, dermatological, neurological and psychiatric disorders, The frequency distribution of the finger print patterns in the 99 s'chizophrenics were whorls 52.45%, loops 49.09% and arches 3.46%. and that of controls were vrhorls 49.65%, loops 46.38% and arches 3.97%, The diffeence in pattern frequency was statistically significant (P<0.05). However, the striking differences were found in the frequency of the ridge dissociation. The observed frequency was very significantly high (p<0.005) in the schizophrenics (16.16%) compared to controls (6.25%). This findings supported the rcport of the Raphael (18%) but the frequency of our controls(6.25%) were not matched with previous study of Abel (The frequency for his 4,000 control was negative. No plausible explanation is not found for the extraordinary high frequency of ridge clissociat,ions in the controls of tbis study. Although rnore extensive investigation in needed for the explanation of significantly high frequency of ridge dissociation in thes chizophrenics, the findings of the present study give us another evidence of the constitutional factors in schizophrenics.

During the course of infectious mononucleosis, intake of ampicillin and its analogues such as amoxicillin may cause hypersensitivity skin rashes. We report herein a case of ampicillin induced skin rash in a 41-year-old female patient with infectious mononucleosis. Infectious mononucleosis was confirrned by datetion of IgM antibody against Epstein-Barr(EB) viral capsid antigen(VCA) in her serum. During the icuteillness, she taked ampicillin for 3 days, and 1 week after the intake of ampicillin, a genertliz:d erythernatous and purpuric maculopapualr eruption developed. Physicians should be careful not to use ampicillin and its analogue if batients are suspected to be infected with EB virus as ampicillin induces severe skin rashes in patients with infectious mononucleosis.

The purpose of this study was to compare the accuracy of currently used elastomeric impression materials for complete arch impression taking. Five elastomers (Impregum, Permlastic, Express, Extrude, Examix) and one Irreversible hydrocolloid (Aroma-fine) were tested. For each material, 5 impressions were made of stainless steel model to which five tapered posts were attached. Custom trays were used for polyether and polysulfide impression materials, and putty/wash two step technique was used for addition polyvinylsiloxane impression materials. Improved stone models were poured to all impressions. Accuracy of the materials was assessed by measuring ten distances on stone dies poured from impressions of the master model. All measurements for master and improved stone models were with three dimensional measuring machine. The results were as follows 1. The dimensional accuracy of polyether, extrude, and examix were significantly superior to polysulfide, exress, and alginate in reproducing full arch mode (p<0.05). 2. There were no statistical differences in dimensional accuracy for full arch impression between polyether, extrude and examix (p>0.05). 3. there were no statistical differences in dimensional accuracy between polysulfide, express, and alginate (p>0.05). 4. There were no statistical differences between addition polyvinyl siloxane materials (p>0.05). 5. There were no statistical differences between anterior-posterior and lateral dimensional changes of all impression materials (p>0.05).
