치내치는 치아 발육 중에 석회화되기 전, 치아의 법랑상피가 일부 함입되어 설측에 깊은 소와를 형성하는 발생학적 변이이다. 주로, 상악 측절치에 호발한다. 치내치는 형태학적으로 다양하며, 종종 초기에 치수괴사에 이르기도 한다. 치내치는 복잡한 해부학적 구조로 인해 치수 치료시 많은 어려움이 따른다. 따라서, 치내치는 초기 진단이 중요하고, 예방적 치료가 추천된다. 이에 본 증례는 치내치를 가진 환아에서의 치료에 관해 보고하고자 한다. Dens invaginatus is a developmental variation resulting from invasination of the tooth crown of root before calcification. Teeth most affected are maxillary lateral incisors. The malformation shows a broad spectrum of morphologic variations and frequently results in early pulp necrosis. Root canal therapy may present severe problems because of the complex anatomy of the teeth. So, the early diagnosis of such malformation is crucial and a preventive approach has been recommended. This report describes three cases of dens invaginatus treatment.

P가 첨가된 미세한 Fe 분말을 사용하여 Fe 및 Fe-Mo-Ni계에 대해 금속사출 성형방법에 의한 소결부품의 제조 가능성에 대해 조사한 결과, 바닝더로 사용한 Methylcellulos의 부피분율이 11vol%, 용매인 뭉의 양이 12wt%일때 우수한 성형성 및 소결특성을 보였다. 사출성형 조건은 다이의 예열온도가 110℃, 다이내의 유지시간이 3분일때 우수한 성형성을 보였으며, 650℃의 온도에서 1시간 유지하였을때 바인더는 완전히 제거되었다. Fe계 사출성형체의 소결시 얻어진 소결밀도는 이론밀도의 90%였으며, 활성제인 P가 소량 첨가됨으로써 소결성이 개선되어 95%정도의 소결밀도를 나타내었다. Using fine powders, the possiblity for the Metal Injection Moulding of the Fe and Fe-Mo-Ni steel with addition phosphours was investigated. The experimental results were obtained as follow; 1. The relative good molding and sintering behavior were obtained by using the binder constituted of 11 vol% methylcellulose and 12w% water solvent. 2. The preheated mould temperature and residence time were 110℃ and 240 sec for the optimal moulding condition. The binder could be fully removed by debinding at 650℃ for 1 hour. 3. The injection moulded Fe-parts could be obtained the relative sintered density about 90%. By addition of the small amount of phosphorus the more densification and then the relative sintered density could be obtained about 95%.

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

Agranulocytosis, one of the major side effects of antithyroid a gents, probably occurs in less than 0.25% of cases treated with antithyroid agents. It usually occurs within the first several weeks or months after the initiation of therapy, when drug dosage is higher. Most reported cases of agranulocytosis have occurred during the first 3 months of therapy. We describe here a rare case that did not experience the side effect for 6 years of antithyroid agent treatment but presented with agranulocytosis in one month after re-exposure. It suggests that the major side effect such as agranulocytosis can occur in patients who had undergone prior uneventful antithyroid drug therapy.

This study examines the unmet medical care needs and their determinants of the elderly who use the public health center located in the city. Secondary analysis was done using the data collected in 1996 from 356 elderly, 60 years or older, living in the community. The data were analyzed by x² test and the multiple logistic regression. Of the subjects, 29.5% had the unmet needs. Joint problem of the lower extremities was the most prevalent symptoms/ illnesses of the unmet needs, followed by rheumatoid arthritis. As for the unmet examinations/treatments, physical therapy was the most prevalent, followed by health examination and dentures. Analysis of the logistic regression mode] revealed subjective physical health as the most important predictor for having an unmet need. Compared to those with "good" subjective physical health, those with "bad," or "very bad" health tend to have an unmet need. The odds of the unmet needs for the old-old decreased by 51.9% compared to the odds of the young-old, which was partly attributed to under-representation of disabled old people. Those with difficulties in subjective economic status tend to have an unmet need. These results suggest the need for delivering medical services to the low- income elderly. Particular attention should be given to providing dentures and to managing chronic degenerative disease.

The concentrations of the immunological substances in breast milk and nutritional status were studied in healthy Korean women of middle socioeconomic class. The subjects were recruited at random from obstetric clinics in Seoul. The nutrients intake, prepregnancy BMI, maternal weight gain during pregnancy were studied. The concentrations of lactoferrin(LF), lysozyme(LZ), sIgA, IgG and C_3 in colostrum, in transitional milk, and in mature milk, were measured. To elucidate the effect of nutritional status on immunological substances, each component was compared on the basis of either BMI, weight gain, or protein intake. The highest concentrations of the substances were found in colostum and decreased as lactation progressed. The decline was more prominent in IgG, C_3, and sIgA, and less significant in LZ and LF. The colostrum of standard weight gain group showed higher concentrations compared to lower weight gain group. This difference became smaller as the lactation progresses. BMI and nutrient intake status had less significant effect. Lower sIgA was found in lower BMI, in lower weight gain, and lower protein intake groups compared to standard groups, which indicates sIgA is the most affected substance among the measured by nutritional status.
