Authors examined the morphology and size in the maxillary lateral insicor from Korean adults and the following conclusion have been drawn. 1. In the shapes of labial surface in maxillary lateral incisors, the quite prominent middle lobe, moderate prominent middle lobe, less prominent midd1e lobe were 20.60%, 69.85%, 9.55%, respectively. 2. In the shapes of incisal margin in maxillary lateral incisors, the arc shaped to the distal, round, nearly straight were 24.96%, 60.20%, 15.11%, respectively. 3. In the shapes of incisal angle in maxillary lateral incisors, the equal sized mesioincisal angle and distoincisal angle, larger distoincisal angle, much larger distoincisal angle were 8.36%. 67.34%, 24.30%, respectively. 4. In the shapes of lingual surface in maxillary lateral incisors, the marked shovel (Ms), semi-shovel (Ss), trace shovel (Ts), no shovel (No) were 43.00%, 33.50%, 19.50%, 4.00%, respectively. 5. The size of the maxillary lateral incisors were as follows. 6. In comparison with Wheeler's data, crown length, crown width and crown thickness were larger in Korean adult, but the degree of cervical curvature were smallest.

The authors analysed bone marrow findings of sixteen cases of culture proven typhoid fever to reveal the pathologic changes according to the disease stage. The most frequent finding was chronic granulomatous inflammation (eight cases). Infection (bacteria) associated hemophagocytic syndrome (four cases), reactive marrow (two cases), and non specific findings (two cases) were also encountered. Granulocytic hyperplasia with hemophagocytosis appeared at the early stage and was followed by infection (bacteria) associated hemophagocytosis and granuloma in proliferative stage. In lysis (late) stage, granulomatous inflammation was noted. However, resolution of granulomatous inflammation was not distinct. Some nuclear debris and phagocytosis were remarkable in well-formed granulomas. Thrombocytopenia was the most remarkable peripheral blood finding at the time of biopsy. Anemia, leukopenia, and pancytopenia were also observed in descending order.

Development of a malignant tumor within a mature cystic teratoma is a serious event, and occurs in about 1%~4% of cases. The malignant transformation occurs most frequently in the squamous epithelium with the formation of a squamous cell carcinoma. There are 10 cases reported in the literature, in Korea. We report 4 additional cases, which include 3 squamous cell carcinomas and 1 adenosquamous carcinomas, arising in cystic teratoma of the ovary.

BACKGROUND: Longer RBC storage will benefit blood banker by reduced outdating and patients by receiving fewer nonviable cells and RBC breakdown products as well as by having the opportunity to participate in markedly improved autologous storage system. METHODS: We rejuvenated whole blood 10 units and RBC 15 units, on 1-3 days after expiration, then they were divided into four, washed, and suspended with four kinds of solutions containing saline adenine glucose, mannitol, and phosphate, in closed system. For the evaluation of RBCs, 30 min saline stability (SS), 2 h SS, % hemolysis, ATP, 2,3-DPG, P50, LDH, potassium, and plasma hemoglobin were tested at every week during 42 days. RESULTS: On 35th day, 30 min SS of RBCs was higher than 88% and % hemolysis of RBCs was lower than 1% in solutions containing phosphate. ATP of RBCs was the 50% of the reference value of healthy persons and 2,3-DPG of RBCs was relatively higher in solutions containing phosphate (SAGMP1, 2, 3) than in solution without phosphate (SAGM). CONCLUSION: We could successfully rejuvenate outdated RBCs and extend the expiration date to additive 35 days, but for practical use, post transfusion RBC survival and safety should be evaluated in the future.

This study was to investigate the various parts of the mandible related to inferior alveolar nerve conductive anesthesia in 228 dry skulls of Korean adults. Five morphological variations were observed and four measurements were undertaken. The following results were obtained. 1. The Position of coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coronoid notch in the middle part of the anterior border of the ramus of mandible) : 83.3% Type II (Coronoid notch in the inferior part of the anterior border of the ramus of mandible) : 12.7% Type III (No coronoid notch in the anterior border of the ramps of mandible) : 4.0% 2. The position of the lingula of mandible to the imaginary line of the molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the imaginary line of the mandibular molar occlusal plane) : 87.3% Type II (Coincide with the imaginary line of the mandibular molar occlusal plane) : 8.6% Type III (Below the imaginary of mandibular molar occlusal plane) : 4.3% 3. The position of the lingula of the mandible in the internal oblique line-posterior border of the ramus of mandible dimension is classified into three types and percentage of each type was as follows : Type I (Anterior part in the internal oblique line-posterior border of the ramus of mandible dimension) : 82.9% Type II (Middle part in the internal oblique line-posterior border of the ramus of mandible dimension) : 11. 4% Type III (Posterior part in the internal oblique line-posterior border of the ramus of mandible dimension) : 5.7% 4. The position of the apex of the lingula of mandible to the deepest point of the coronoid notch in the anterior border of the ramus of mandible is classified into three types and percentage of each type was as follows : Type I (Coincide with the deepest point of the coronoid notch) : 82.0% Type II (Above the deepest point of the coronoid notch) : 13.2% Type III (Below the deepest point of the coronoid notch) : 4.8% 5. The position of the apex of the lingula of mandible to the imaginary line of the mandibular molar occlusal plane is classified into three types and percentage of each type was as follows : Type I (Above the 8mm) : 65.7% Type II (Above the 5mm) : 18.6% Type III (Above the 10mm) : 15.7% 6. Angle between the line connecting the apex of the lingula of mandible-1-2 premolars in the contralateral side and median line of the mandible is classified into three types and percentage of each type was as follows : Type I (50°) : 67.2% Type II (45°) 21.4% Type III (55°) : 11.4% 7. The averages of the measurement of the various bony landmarks of the mandible related to inferior alveolar nerve conductive anesthesia were as follows : ① Distance from deepest point of the coronoid notch to internal oblique line : 9.2mm ② Distance from internal oblique line to the apex of the lingula of mandible : 11.6mm ③ Distance from deepest point of the coronoid notch to apex of the lingula of mandible : 19.7mm ④ Height of the lingula of mandible : 9.8mm

BACKGROUND: The purpose of this study is to prove that human infection of Yersinia pseudotuberculosis might be occurred by drinking of mountain spring water contaminated with wild mice excreta through epidemiological tool. METHOD: Y. pseudotuberculosis strains which were isolated from patient stools, mountain spring water and mice excreta were analysed by serotyping of O antigen and plasmid DNA profile (Restriction Endonuclease Analysis of Plasmic DNA analysis REAP) assay Also reservoir rate of Y. pseudotuberculosis was calculated from wild mice which were captured throughout Korean mountains. RESULTS: Reservoir rate of Y. pseudotuberculosis from wild mice in Korea was 0.85% and was not higher than that in other country. The analysis of 66 strains of Y. pseudotuberculosis showed that 36 strains of serotype 15, REAP B type, 24 strains of serotype 4b, REAP D type, and 1 strain of serotype 4b, REAP new unclassifiable type, but 5 strains didn't have plasmic (serotype 15:3, 11 :2) .Especially same 4b, D type of Y. pseudotuberculosis was isolated from patient stools, mountain spring water and wild mouse (Apodemus agrarius) excretion and this fact was considered that Y. pseudotuberculosis strains from 3 groups were closely correlated epidemiologically. Also serotype 15, REAP B strains were isolated from patient stools and mountain spring water, but were not isolated from wild mice yet and 15, B type was isolated from Korea only and considered as native Korean strain which had not isolated in other countries yet. CONCLUSIONS: Human Y. pseudotuberculosis infection in Korea was occurred by drinking of contaminated mountain spring water and A. agrarius was one of main reservoir which contaminates mountain spring waters in Korea, Also above antigenic distribution of Y. pseudotuberculosis would be useful for development of ELISA kit of Korean type.
