비성형수술에 삽입하는 사용물로는 자가연골이 가장 이상적이지만 필요한 만큼의 충분한 양을 얻기가 힘들고, 수술시간이 길어지며, 흡수가 일어날 수 있다는 단점이 있다. 이러한 단점을 극복할 수 있는 이종이식물 중에서 고어텍스는 최근에 개발되어 사용이 점차 증가하고 있는 추세이지만 아직까지 고어텍스의 임상적 효용성에 대한 보고는 드물다. 저자들은 고어텍스를 5명의 융비술 환자에서 사용하였는데 3명은 연골과 같이, 2명은 고어텍스 단독으로 사용하였다. 이 중 1명에서 감염이 발생하여 고어텍스를 제거하고 늑연골을 이용하여 융비술을 다시 시행하였고 나머지 4명은 모두 만족스러운 결과를 얻었다. 평균 20개월의 추적관찰에서 이식물의 이동이나 탈출, 피부의 손상 등의 큰 부작용이 없어 고어텍스가 비성형, 특히 융비술에 유용하다고 판단되어 관련문헌 고찰과 함께 보고하는 바이다. Though autogenous cartilage remains the ideal graft material in nasal surgery, situations exist where an alternative or an additional grafting material is needed. Gore-Tex is one of most recently developed alloplastic material and has been widely used for rhinoplasty. But there are few reports about the clinical efficacy of this material in rhinoplasty. The authors used Gore-Tex as a nasal implant in 5 cases of augmentation rhinoplasty. In three patients, the Gore-Tex was used with septal or conchal cartilages because the cartilages were not enough for the needed augmentation. In one patient, the implant was removed due to postoperative infection and subsequent augmentation was done with autogenous rib catilage after infection control. During average 20 months of follow-up, complications such as absorption, mobilization, or extrusion of the implant and thinning of the nasal skin were not found. All patients were satisfied with the surgical results. From these results, Gore-Tex can be considered as an effective material in augmentation rhinoplasty when autogenous material is not available or is not sufficient for the proper augmentation.

Tectonic investigation is very important to understand the seismic environments. Many strong seismic activities are found to be closely related with pre-existed discontinuous planes of the crust, such as faults. Here we describe an example of the Quaternary faults occurring in the vicinity of the Ulsan fault near Ipshil-ri, Oedong-up, Ky o ∨ ngju city to enlight a seismic activity evaluation. This fault is thought to be the contact boundary between the Cretaceous to early Tertiary granite and andesite, and also cut the Quaternary formation which unconformably overlies granite and andesite. General strike of the fault plane is N-S, dipping 70° to the east. Along this fault plane, two different faulting events are distinguished; (1) reverse faulting with up to 5m of displacement in the Quaternary formation, and (2) normal faulting with 50° northerly plunging striation within the Quatenary fault plane. We suggest that these faultings are related to the WNW-ENE compressional tectonic environments during late Quaternary, and to the readjustment of accumulated strains by the pre-compressional tectonic environments. The age of the Quaternary formation is not fully investigated, however, this Quaternary fault is probably one of the active faults which has been rarely described in Korea.

These experiments were performed to know whether sanjoinine A, a component of the alkaloid fraction of Semen Zizyphi Spinosi, acts as an anti-convulsive agent in the kainic acid (KA)-induced experimental convulsion model and whether these effects are mediated by decreased intracellular calcium. Oral administration of sanjoinine A (4 and 8 mg/kg) increased the survival rate and latency of convulsion onset, and decreased the seizure scores and the weight loss induced by intraperitoneal (i.p.) injection of KA (50 mg/kg) in mice. In addition, sanjoinine A protected against neuronal damage and apoptosis in the hippocampus after KA administration, as analyzed by using immunohistochemistry and TUNEL assay. Sanjoinine A also significantly blocked seizure-form electroencephalogram alterations induced by KA. Moreover, in cultured rat neuronal cells, sanjoinine A inhibited KA-induced cell death, as measured by propidium iodide detection. Sanjoinine A also increased intracellular chloride and inhibited the elevation of intracellular calcium induced by KA. Sanjoinine A, therefore protects against KAinduced convulsions by increasing intracellular chloride and reducing intracellular calcium levels.
