The aerozolization is one of possible Brucella transmission mechanisms, particularly in air-borne exposed laboratory workers. In this study, seven laboratory workers were potentially exposed to B. abortus via aerosols. Two laboratory workers who sniffed an agar plate several times were considered to be at high risk for acquiring the disease, 5 workers who did not work directly with the strain were be considered at low risk of infection. Prophylactic antibiotics of doxycycline 200 mg/day and rifampin 600 mg/day were offered for 6 weeks in high risk workers and 3 weeks for low risk workers respectively. Enrolled workers were advised to check for serological testing of Brucella species every 3 weeks during a total period of 12 weeks. Compliance with taking medicine was 57.1% (4/7) and compliance for completing the serological tests was 85.7% (6/7). None of the laboratory workers developed clinical disease or tested positive serologically during 3 months of seroloaical testing and 1 year of clinical follow-up.

In order to evaluate clinical utilities of Tc-99m MIBI dipyridamole stress myocardial SPECT in patients with coronary artery disease (CAD), we compaired tomographic and polar map images of Tc-99m MIBI myocardial SPECT with the results of coronary angiography in 25 patients with CAD (myocardial infarction 13,angina pectoris 12) in Chungnam National University Hospital from Oct. 1991 to Oct 1993. Percutaneous transcoronary angioplasty (PTCA) was done in three patients of 25 CAD patients and follow up SPECT studies were done in same three patients within 2 months after PTCA. The results were as follows : 1. Mean age of patients was 57.4 years. Man was 2.7 times more than woman. 2. Sensitivity and specificity of Tc-99m MIBI myocardial SPECT for the detection of coronary artery stenosis in patients with myocardial infarction were 92.7 % anf 85 %, respectively. 3. Sensitivity and specificity of Tc-99m MIBI myocardial SPECT for the detection of coronary artery stenosis in patients with angina pectoris were 100 % and 67 %, respectively. 4. After PTCA size of perfusion defects in stress SPELT images was decreased in all three patients . With the results above,we thought that Tc-99m MIBI myocardial SPECT is useful noninvasive method to detect stenosed coronary artery in patients with CAD and it can be used as a method to evaluate the result of PTCA.

Upper cuspid impation is a serious that occurs with sufficient frequency to justify diagnosis and intervention as early as a dental age of 8 years. The maxillary cuspid follows a more difficult and tortuous path of eruption than other tooth. Where upper arch crowding prevents such a tooth from following its normal eruption path, it will diverted either buccally or palatally. The diagnosis of canine impaction is on both clinical and radiographic examinations. When clinician detects early signs of ectopic eruption of canines, an attempt should be made to prevent theier impaction and its potential sequelae. Screening consists of identifying patients who lack a normal cuspid bulge on palpation, with follow-up radiographic evaluation where indicated. Selective removal of deciduous cuspids is a suggested interceptive measure in class Ⅰ uncrowded malocclusions. Each patient with an impacted canine must undergo a comprehensive evaluation of the malocclusion. The clinician should then consider the various treatment options available for the patient. Surgical exposure of the canine and orthodontic treatment to bring the tooth into the line of occlusion is the most desirable approach. After the surgical exposure of the impacted tooth, an auxiliary(button) is attached to the crown. It should be reemphasized that in the surgical exposure of an impacted tooth, only enough bone should be removed to allow for the placement of a bracket and that during the procedure the CEJ should not be intentionally exposed. The removable appliance was designed This applied traction along a desired path of eruption using elastics changed daily Removable appliance seemed to offer more in vertical anchorage than did the fixed appliances. 13 year-old male and 14 year-old female with impacted maxillary canine were treated with surgical exposure and direct traction.

The purpose of this study was to examine the mechanism of improving acid resistance of Nd-YAG laser irradiated tooth enamel and determine the most effective energy density for improving acid resistance. The bovine tooth enamel were lased with a pulsed Nd-YAG laser. The energy densities of exposed laser beam were varied from 10 to 70 J/㎠. To investigate the degree of improving acid resistance by irradiation, all the samples were submerged to demineralize in 0.5 N HCIO₄ solution for 1 minute. After 1 minute, 0.05% LaCl₃ was added to the solution for interrupting the demineralization reaction. The amounts of dissolved calcium and phosphate in the solution were measured by using an atomic absorption spectrophotometer and the UV/VIS spectrophotometer, respectively. To examine the mechanism of improving acid resistance, X-ray diffraction analysis, infrared spectroscopy, and scanning electron microscopy were taken. The X-ray diffraction pattern of the samples were obtained in the 10。∼80。2θrange with Cu-Kαradiation using M18HF(Mac Science Co.) with X-ray diffractometer operating at 40 KV and 300㎃. The infra-red spectra of the ground samples in 300 ㎎ KBr pellets 10 mm diameter were obtained in the 4000 cm to 400 cm range using JASCO 300E spectrophotometer. The scanning electron microscopy was carried out using JSM6400(JEOL Co.) with 500∼2000 times magnification. The results were as follow 1. The concentration of calcium dissolved from laser irradiated enamel with 50J/㎠ was significantly lesser than that of unlased control group (p<0.05) 2. From the result of the X-ray diffraction analysis, β-TCP, which increases acid solubility, was identified in lased enamel but the diffraction peaks of (002) and (004) became sharp with increasing energy density of laser irradiation. This means that the crystals in lased samples were grown through the c-axis and subsequently, the acid solubility of enamel decresed. 3. The a-axis parameter was slightly increased by laser irradiation, whereas the c-axis parameter was almost constant except for a little decrease at 50J/㎠. 4. In the infra-red spectra of lased enamels, phosphate bands (600∼500 cm), B-carbonate bands (870, 1415∼1455 cm), and A-carbonate band (1545 cm) were observed. The amounts of phosphate bands and the B-carbonate bands were reduced, on the other band, the amount of the A-carbonate band was increased by increase the energy density. 5. The SEM experiments reveal that the surface melting and recrystallization were appeared at 30 J/㎠ and the cracks were observed at 70 J/㎠. From above results, It may be suggested that the most effective energy density for improving acid resistance of tooth enamel with the irradiation of Nd-YAG laser was 50J/㎠. The mechanism of improving acid resistance were reduction of permeability due to surface melting and recrystallization of lased enamel and reduction of acid solubility of enamel due to decrease of carbonate content and growth of crystal.

The authors compared two hundred forty-eight imprisoned soldiers with two hundred seventy-nine normal controls using MMPl and Ego-Strength Scale in R.0.K. Army. The results were as follows ; 1) Mean age of imprisoned soldiers was 23.4, while that of controls was 23.9. 2) Educational level of imprisoned soldiers was lower than that of normal controls. 3) Pre-enlistment occupations in imprisoned soldiers chiefly were employees and factory workers (39.9%), while students consisted of 54.4% in normal controls. 4) More than half(61.4%) of the criminal acts had occured during the first year of the military service 5) Of the various criminal acts, absence without leave was the most frequent criminal activities(50.6%). 6) The result of MMPI was significantly different between two groups except L subscale. More specifically, F, Ma, Sc, Pd, Pa subscales which indicate a tendency of behavioral acting out were high in imprisoned soldiers, but all subscales showed below scores of 65. 7) Scores of Ego-Strength Scale in imprisoned soldiers were lower than that of the controls.

전위 배복된 상악 측절치와 상악 견치의 치험례

이기영,최형준,손홍규 大韓小兒齒科學會 1999 大韓小兒齒科學會誌 Vol.26 No.4

치아의 전위는 매우 드문 치아 기형의 하나로서 발생 또는 맹출중 인접한 2개의 영구치의 위치가 서로 바뀐것을 말한다. 전위는 상악과 하악 모두에서 발생 가능한데 그중에서 상악에서의 발생이 더 흔하며 상악견치는 가장 호발하는 치아이다. 상악에서는 상악 견치와 제 1 소구치와의 전위가 가장 빈도 높고 그 다음으로 상악 견치와 측절치와의 전위가 많다. 전위는 완전 전위와 불완전 전위로 나눌수 있는데 완전 전위는 치관뿐 아니라 치근의 위치까지 전위된 경우를 말하고 불완전 전위는 치근의 위치는 정상이고 치관만 전위된 경우이다. 전위의 원인에 대하여 명확하게 밝혀진 것은 없으나 유치의 만기잔존이나 조기상실, 발생중의 전위나 정상 맹출 경로로부터의 이탈, 유치열시기의 안면외상 등이 제기되고 있고 이밖에 과잉치, odontoma 또는 odontogenic cyst, 염증성 병소 등을 그 원인으로 생각해 볼 수 있다. 본 증례는 유치열시기의 안면외상으로 인하여 상악 영구 견치와 측절치의 전위가 발생한 경우로서 치료후 전위된 위치로의 양호한 배열을 이루었다. Transposition has been described as an interchange of position of permanent tooth and is relatively rare dental anomaly. Transposition of teeth may occur both in the maxillary and mandibular arches. but it appears more often in the maxilla of individual teeth, the maxilla canine is the most often involved. A canine transposes most often with a first premolar and less frequently transposes with a lateral incisor. Incomplete transposition is a condition describing an interchange in the position of the crowns of two permanent teeth, while the root apices remain in their relative position. Complete transposition is a situation in which both the crowns and entire root structure are transposed. The etiologic factors of transposition are tooth buds interchange, retained deciduous canines, migration of the erupting canine, trauma to deciduous teeth etc. This report describes a case of a transposition between a maxillary left canine and a lateral incisor and impaction of a maxillary left central incisor due to trauma to deciduous dentition.

The 1.06㎛ Neodymium-YAG Laser(800 micron hemisherical) is revealed a useful tool for percutaneous laser disc decompression(PLDD). Especially PLDD would be applied to the management of lumbar disc herniation with minimal intervention. Total irradiated energy to one level of disc space was bout 1000 to 2000 joules. We performed this method at 10 levels, in 7 cases of patients, consisting of 4 males and 3 females with an average age of 37.7 years. Five cases showed excellent and good results, were observed. In two cases, open surgery was required because of unsatisfactory results. The best results were obtained in the protrusion type of disc herniation. We have summarized some advantages of PLDD: a) safe and simple procedure in an outpatient setting, b) avoiding general anesthesia, late spinal instability, c) possibility of repetitive use.
