The effect of oriental medicines an the growth of oral bacteria(B. pumilus JU4, B. coagulans JU6, B. subtilis var globigii JU7 and B. subtilis var. globigii JU9) which were isolated from teeth, gums and tongues of patients was investigated. lt was shown that the water extracts of Glycyrrhiza glabra L. var. glandulifera Regel et Zucc., Schizandrae Fructus and Coptidis Rhizoma have the strong antimicrobial activity against every test organism. Especially, the water extract of Schizandrae Fructus has the most antimicrobial activity against all test bacteria of which MIC were the same as 0.25%. The growth of oral bacteria B. pumilus JU4 was inhibited by addition of the water extracts of Glycyrrhizae Radix, Schizandrae Fructus and Coptidis Rhizoma in the concentration of 0.9%, 0.2% and 0.1% respectively. It was tested that specific growth rates of B. pumilus JU4 in each concentration of the water extracts of Glycyrrhizae Radix, Schizandrae Fructus and Coptidis Rhizoma. From the results, the test showed that mean of specific growth rates of B. pumilus JU4 decreased 102%, 186% and 210% in 3% concentration of the water extracts of Glycyrrhizae Radix, Schizandrae Fructus and Coptidis Rhizoma more than those in control respectively.

외배엽 이형성증은 무한증, 감모증, 무치증 등의 한가지 이상의 외배엽기관의 선천적 이상소견이 특징인 유전성 질환이다. 이런 증상을 가진 어린이들은 치조골 발육의 부족으로 수직고경이 감소하여 노인과 같은 안모를 가지게 되며 저작, 발음, 심미적 장애와 그로 인한 정서적 문제가 있다. 이런 어린이에게 보철적 치료를 통해 수직고경을 회복하고 기능과 심미를 개선하는 것을 중요한 의의를 가진다고 할 수 있다. Magnetic attachment는 자성의 힘을 이용하여 가철성 의치를 지대치로 연결해 유지와 안정을 얻어내는 장치로 유지안정은 물론 심미적으로도 우수하다. 본 증례에서는 원광의료원 치과병원 소아치과에 내원한, 부분적 무치증을 동반한 외배엽 이형성증 어린이에서 magnetic attachment를 이용한 보철치료를 시행하여 양호한 결과를 얻었기에 보고하는 바이다. Ectodermal dysplasia is a hereditary disease characterized by congenital dysplasia of one or more ectodermal structures. Intraorally, common findings are anodontia or oligodontia, conical teeth, and, consequently, generalized spacing. This case presented the oral rehabilitation of a child with hypohidrotic ectodermal dysplasia. Oral rehabilitation is important from functional, esthetic, and psychologic perspective. Due to the absence of teeth, the volume of alveolar bone and its growth are decreases, resulting in a loss of vertical dimentsion and protuberant lips. The treatment involved increasing the patient's vertical dimentsion of occlusion, fabricating a maxillary partial denture, and using magnets to help retain the mandibular partial denture. A 5-year 7-month old Korean boy was referred to the pediatric department for examination, evaluation and treatment of his disorder, we used magnets on #73 and #83 for enhanced retention of a mandibular overdenture. The magnet used in this case was the Magfit system(GC Co., Japan).

Experiments were conducted to investigate the atomization characteristics of rice-bran oil which is an alternative fuel. For the study, an ultrasonic system, an injection system, and six different nozzles(three kinds of single-hole type and three kinds of pintle-type) were made To investigate the effects of ultrasonic energy on a high viscous fuel, an immersion method and a phase doppler particle analyzer were used for the measurements of droplets distribution. Diameters of rice-bran oil droplets were apparently decreased by applying the ultrasonic energy, with the increasing open pressure, and when samples were collected at more distant position from the nozzle.

The double teeth include Gemination and Fusion. The congenital missing teeth is the absence of the tooth. The purpose of study was to investigate the prevalence of double teeth and congenital missing teeth in preschool children of Iksan city. The study population consisted of 1,031 children, 569 boys and 462 girls, ages 17 to 84 months. The double teeth possess a variety of diagnostic and treatment problems. Gemination is the partial splitting of a single bud into two distinct entities that remain joined in a Siamese twin fashion. Fusion is the joining of two buds. Both may be normal, or one may be a supernumerary. Congenital missing is the absence of one or a few teeth. Twenty three(11 boys and 12 girls) of the 1,031 children had double teeth and 18(8 boys and 9 girls) exhibited congenital missing of teeth. The prevalence of Double primary teeth was 2.2%. The prevalence of congenital missing teeth was 1.6%. One subject had double teeth and congenital missing tooth at the same time. Of the 17 cases of congenital missing teeth, one girl showed it in the maxilla and five boys and six girls had them in the unilateral side of the mandible. There were no significant differences in the prevalence of double teeth ad congenital missing teeth between the boys and the girls.

Background: The traumatic spinal injury is an extremely serious condition that often results in death or disabilities. We investigated epidemiological data on spinal injuries specifically in severe trauma patient admitted to a preliminarily proposed Major Trauma Distinctive Care Center. Materials and Methods: We reviewed the medical records of 28 severe trauma patients (Injury Severity Score >15) with traumatic spinal (vertebral column or spinal cord) injuries admitted to the emergency medical center in the Kosin University Gospel Hospital (KUGH) from January to October 2009, retrospectively. Results: The ratio of male to female was 3 to 1. The mean age was 46.5 years. The leading causes of traumatic spinal injury are falls (39.4%). The most common level of injury was cervical (35%) and lumbar (35%) spine. Spinal fracture accounts for 47.8% of all traumatic spinal injury, spinal cord injury 37%, dislocation 8.7% and HNP (herniated nucleus pulposus) 6.5%. The most common type of spinal body fracture was compressive type (58.8%). In spinal cord injury, incomplete injury (64.7%) was more common than complete injury (35.3%) and quadriplegia accounts for 47.1% and paraplegia 52.9%. The most common associated injury was rib fracture & pneumohemothorax (31.2%). 5 patients underwent surgery earlier than 24 hours. The average Injury Severity Score (ISS) was 24.2 and the average Abbreviated Injury Scale Score (AISS) was 3.5. Conclusion: This clinical analysis is the first basic study for understanding the patterns of the spinal injuries in the severe trauma patients admitted to KUGH emergency medical center which was preliminarily proposed as Major Trauma Distinctive Care Center by Ministry for Health, Welfare and Family Affairs in November 2008. Although this study has only small number of cases during relatively short term period, it will be touchstone of succeeding analysis of spinal injuries in the severe trauma patients. Therefore continuous additional data collections and more precise clinical investigations are suggested
