The sagittal split ramus osteotomy(SSRO) of the mandible has used one of the most popula methods for the correction of various dentofacial deformities, especially mandibular prognathism. In SSRO, there are produced bony gap following mandible setback because of mandibular flaring. For this reason, the condylar axis may be changed due to bony approximation both segment in three dimension more mesio-laterally. According to change of condylar position, the condition of TMJ structure are changed and change of TMJ symptoms are suggested theoretically, and the correction of malocclusion by SSRO may improve the TMJ symptoms by improvement of feeding difficulties. The pupose of this study was to determine relationship between expected alterations in condylar position and suggested TMJ symptoms produced by change of condylar position. TMJ symptoms of 15patients who had operated SSRO are checked at about postoperative 6 month ranging $5{\sim}11$ month. Anterior-posterior position of condyle which was comparison preoperative with postoperative position, was classified 5 groups. The author tried to identify relationship between positional change of condyle and TMJ discomfort.

This research experimented on the change of the multiple colleague scan angle facing one scan object facet to many directions of the form of 3D about the visual angle nervous system forming the cubic distribution with the gradient magnetic field of the mri system and considered the existing basic angle oblique direction test coverage and comparison. MR system can freely select various pulse sequence and image slice. To oblique imaging for optic nerve viewing, we have studied the variation of scan angle between typical oblique scan method (sagittal-coronal plane) and multi directional angles oblique scan method (sagittal-coronal-axial plane) using gradient of MR system. In this study, the subjects of the experiment were normal adults in our country. As a result, we confirmed that multi directional angles oblique scan method can display anatomical information of more wider area than typical oblique scan method. In addition, to clearly display optic nerve, we also confirmed that image slice thickness and pulse sequence have effect on it.

스트레스로 인한 인체의 반응은 중추신경계, 시상하부, 변연계 및 기타 표적기관으로부터 시작되는데, 자율신경계 반응, 내분비계 반응, 면역계 반응 등을 통하여 복합적인 신체 증상으로 발현되며, 스트레스 상황에서는 시상하부-뇌하수체-부신 축 (HPA axis)과 교감신경계의 작용으로 여러 신경전달물질 방출에 변화가 생기며 이러한 변화는 면역기전에 중요한 역할을 하고 일부는 면역세포의 활성에 직접적으로 영향을 미쳐 신체 각종 질병의 원인이 될 것으로 추정된다. 한의학에서는 천인상응(天人相應)의 관점에서 육기(六氣)를 생체자극의 외적 요인으로 간주하고, 생체내적 현상인 정신이 외적 자극을 통하여 나타나는 생체반응을 칠정(七情)으로 보았으며, 이러한 관점에서 스트레스는 신체에 오장(五臟)의 허실(虛實), 혈허(血虛), 정손(精損), 기역(氣逆), 기(氣)의 순환장애, 담연(痰涎), 화(火) 등의 병적인 요인을 만들어 준다. 본 연구에서 재료로 사용된 호초 (Piper nigrum Linne)는 후추나무의 과실을 말린 것으로서 세계적으로 널리 사용되는 향신료이며, 한의학에서는 온중제한하기(溫中除寒下氣), 쾌격소담(快膈消痰), 해독(解毒)등의 효능으로 한담식적(寒痰食積) 완복냉통(脘腹冷通) 곽란(癨亂) 토사(吐瀉)등의 치료에 활용되어 왔다. 특히 쾌격소담(快膈消痰)하는 작용은 정신적 스트레스에 유효할 것으로 생각되므로 본 연구에 이용하게 되었다. 실험동물은 ICR계 생쥐를 이용하였으며, 심리적 스트레스는 옆쪽 cage에서 다른 마우스의 신체에 가해지는 전기 충격을 하루 1시간 동안 지켜보게 하는 것으로 유발하였으며, 이 상태에서 약물을 투여한 그룹을 실험군, 그렇지 않은 그룹을 대조군으로 하였다. 정상군은 아무런 자극 없이 하루 1시간 동안 일정 공간에 가두어 두는 것으로 하였다. 실험 결과, 호초(胡椒) 추출물을 100mg/kg/day 용량으로 5일간 투여한 실험군은 아무런 처치를 하지 않은 대조군에 비해 혈장 중 corticosterone 함량이 유의하게 감소되었고, 뇌에서의 noradrenalin 분비량이 유의하게 증가되었으며, plus maze test에서의 머무름 시간이 연장되는 것으로 나타나 호초(胡椒)가 심리적 스트레스를 효과적으로 억제하고 진정작용이 있는 것으로 사료되나 구체적인 작용기전 및 인체에서의 효과에 대해서는 향후의 보다 자세한 연구가 필요할 것으로 생각된다.

The purpose of this study is to confirm the double of optic foramen in Korean and apply it to the Rhese method. First, the angle between the right optic foramen and the MSP was measured on the axial image using MPR technique of the 3D CT. Second, we measured the angle between the right optic foramen and OML in sagittal of MPR images. As a result, the angle between the optic foramen and the MSP was $39.9{\pm}4.63^{\circ}$ on average, which was different from the $53^{\circ}$ presented by Rhese method(p<0.05). The angle between optic foramen and OML was $40.8{\pm}6.6^{\circ}$. In conclusion, this study confirms that the standard of the Rhese method proposed in current textbook is difficult to apply to Koreans. Therefore, it is necessary to study angle of Korean standard in various general x-ray technique.

The tissue levels of ornithine decarboxylase (ODC) during the estrous cycle and pregnancy were investigated in the pig. Sexually mature female cycling pigs were used. One animal was sacrificed on estrous cycle days 3, 10, 17, 18, 19, 20 and during pregnancy on day 11. 12, B. 14, 18, 19, 20, 48, 50 and 52. Tissues from the hypothalamus, pituitary, uterus, ovary and skeletal muscle were removed. They were homogenized in buffer, and supernatants were used for measurement of protein concentration and ODC activity. The release of $^14$CO$_2$ from radiolabeled ornithine was proportional to the amout of protein added over the range of 0.125~4mg and to the incubation time. ODC appered to have some relationship with the biological functions of the pituitary, ovary and uterus during the reproductive period, especially on day 19 of the estrous cycle, while it showed no such activities in hypothalamus and skeletal muscle of mature pigs. Uterine tissues had significantly more ODC activity than other tissues tested(p < 0.05).

Objective : The goal of this study was to investigate neurological mechanism of emotional regulation and to examine the relationship between the regulation and sensory processing. Subjective : Emotional regulations are mainly processed in limbic system, particularly the basal-lateral group of amygdala takes on a major role in the regulations. The basal-lateral group of amygdala links to thalamus directly and/or indirectly which processes sensory information together. This sensory information connects to orbital and medial prefrontal cortex. Inadequate sensory processing may cause difficulties in emotional regulations and behaviors because of a circuit linking the amygdala, the thalamus, and the orbital and medial prefrontal cortex. These difficulties and impairments has been reported in neurological studies for children with ASD and ADHD. Conclusion : Neurological states are different between the normal children and children with ASD and ADHD and these represent various aspects in sensory processing, emotional regulations and behaviors. Thus, therapists working with children with ASD and ADHD need to understand mechanisms of sensory processing and emotional regulations in order to provide adequate treatments.

Introduction: We report a rare case in which the symptoms of hypersomnia were caused by cerebral infarction that occurred in the hypothalamus and hypothalamus. Case Presentation: The patient underwent Korean medicine treatments using Gami-seonghyangjeonggi-san, acupuncture, electroacupuncture, and physical therapy for 37 days. We evaluated the degree of improvement in hypersomnolence based on the amount of sleeping time and the degree of memory impairment with the patient's suggestive conditions as observed by the patient's guardian, and one-sided facial palsy using the Yanagihara Scale. As treatment was applied, sleeping time was decreased from 22 to 9 hours a day. Memory impairment did not show clear improvements as the patient could not recognize others when they visited during the period in which the patient underwent treatment. One-sided facial palsy showed no improvements and there were no changes in the Yanagihara Scale results. Conclusion: This case showed that Korean medicine treatment could be effective to relieve some of the symptoms of thalamus and hypothalamus infarction. Further research is needed to confirm the effectiveness of Korean medicine treatment.

This study was intended to evaluate a post-operative relapse tendency in mandibular prognathism patients with open-bite. 18 patients with or without open-bite have undergone sagittal split ramus osteotomy and were investigated radiologically with cephalogram. The results were as following 1. The preoperative anterior facial height, mandibular plane angle and mandibular gonial angle were larger in open-bite patients than in nonopen-bite patients.(p>0.05) 2. There was significant correlation between surgical change of SNA, mandibular plane length and long-term relapse.(p<0.01). 3. There was relatively stable postoperative anterior facial height in open bite patients. 4. There was no significant correlation between the surgical change of mandibular plane angle, amount of mandibular setback and long-term relapse.(p>0.01) 5. This study showed that horizontal relapse was more significant than vertical relapse.

Hepatopulmonary syndrome is a triad that includes: hepatic dysfunction, intrapulmonary vascular dilatation and abnormal arterial oxygenation. The incidence of intrapulmonary vascular dilatations, in adults with end-stage liver disease, has been reported to be 13% to 47%, however the incidence in children is unclear and the cases in Korean children have never been reported. The hepatopulmonary syndrome may occur as a result of chronic liver disease following nonalcoholic steatohepatitis in children with hypothalamic or pituitary dysfunction. We report a case of hepatopulmonary syndrome in a 13-year-old child who had rapidly progressive liver dysfunction secondary to panhypopituitarism after craniopharyngioma resection. Careful monitoring and treatment of endocrine abnormalities and metabolic status, as well as liver function, are required in all children undergoing pituitary tumor resection.
