Transarterial chemoembolization is one of the most representative procedures for puncture of the femoral artery. In addition, the same procedure is often repeatedly performed many times, and Hepatocellular carcinoma patients due to cancer is significantly lowered blood tests, regardless of platelet counts are not good enough to stop bleeding. More importantly, hepatocellular carcinoma has a high degree of complication and disease severity, which makes it less likely that the condition of the body will be relatively inferior to other patients. In order to prevent delayed hemorrhage of the femoral artery puncture site after the procedure, it is advised to absolutely stabilize the limb so that it does not bend the limb for 3 hours after climbing in the ward. Therefore, I have been complaining about inconvenience. In addition, in order to prevent delayed hemorrhage after hemostasis, balloon type hemostatic device was used instead of sand bag which was placed on hemostatic site. The results of this study were compared with the results of actual application. The use of a balloon-type hemostatic device to increase the effectiveness of continuous hemostasis and to minimize the inconvenience during the time of patient's absolute bed rest, rather than raising the sandbag to prevent primary delayed hemorrhage by various methods in transarterial chemoembolization. It can be used as a substitute for existing sand bags because it can alleviate pain, increase satisfaction, and can be used as a disposable one.

Before impression making in the fixed restorations or other prosthesis, hemostatic solutions are used for hemostasis and moisture control. Hemostatic solutions effectively control bleeding but their major ingredients, acid removes smear layers which are formed in the tooth preparation, exposes the dentinal tubular orifices which are occluded by smear layers, makes dentinal tubular fluid displace more easily to the various external stimulus, and according to the hydrodynamic theory, consequently causes dentin hypersensitivity. To know the effect of hemostatic solutions on dentin permeability, coronal dentin discs, 1mm in thickness, were prepared from extracted third molars free from decay and wear, and a split chamber device was used. Hydraulic conductance values and SEMs, which were measured before and after treatment with $Astringedentr^{(R)},\;Altract^(R)\;and\;Epri-dent^{(R)}$, were compared and ana-lysed. The following conclusions were drawn: 1. Hydraulic conductance values which were measured after the treatment of hemostatic solutions were increased in all groups(p<0.05). 2. %change values of hydraulic conductance were compared but no significant difference was found among the three hemostatic solutions(p<0.05). 3. On SEM observations of all groups, after treatment smear layers were removed and dentinal tubular orifices were partially exposed. On the basis of these conclusions, the reckless use of hemostatic solutions should be restricted, and when in use, various methods should be considered to protect dentin.

Purpose: The purpose of this study was to examine the effects of bed angles and bed rest time combined with hemostatic methods on discomfort and hemorrhagic complications in patients after transfemoral cerebral angiography. Methods: Data were collected from 93 inpatients following transfemoral cerebral angiography, from April 20 to September 23, 2016. Patients were grouped according to bed angle ($0^{\circ}$ vs. $30^{\circ}$) and bed rest time combined with hemostatic methods (4-hour bed rest after manual compression vs. 2-hour bed rest after applying vascular closure device). Results: There was a significant group differences on discomfort (F=46.44, p<.001). The post-hoc analysis showed the lowest score of discomfort in those with bed angle $30^{\circ}$ and 2-hour bed rest. There was no difference in hemorrhagic complications among 4 groups. Conclusion: The postangiograpy discomfort can be effectively reduced with the least hemorrhagic complications by bed angle $30^{\circ}$ elevation and 2-hour bed rest after applying vascular closure device for those underwent transfemoral cerebral angiography.

피브로인과 세리신은 누에고치로부터 얻어지는 천연단백질로 생체적용 의료용 소재 제작을 위해 각광받는 재료 중 하나이다. 이들 단백질로 만들어진 생체재료는 생분해 시 아미노산으로 분해되어 인체에 흡수되므로 인체에 해롭지 않다는 장점을 가지고 있다. 본 연구에서는 누에고치로부터 세리신과 피브로인을 분리하여 수용액을 제작한 뒤, 이들의 조성비를 달리하거나 또는 첨가물을 혼입하여 다양한 용도로 활용 가능한 실크 스펀지를 제작하였다. 제작된 실크 스펀지의 형태와 안정성 및 혈액 흡수력 등의 특성을 관찰하였다. 세리신 함량이 늘어날수록 실크 스펀지의 구조 안정성은 현저히 떨어졌으며, 실크스 펀지를 70%와 100% 에탄올에 각각 결정화를 유도시킨 결정화 구조는 70%에서 결정화된 스펀지의 형태가 더욱 안정된 것을 확인할 수 있었다. 실크 외의 다른 첨가물을 혼입한 스펀지는 실크구조 안정성이 실크단백질 (피브로인, 세리신)만을 이용하여 제작한 스펀지에 비해 매우 떨어졌다. 실크단백질만을 이용하여 만든 스펀지에 대한 혈액 흡수도는 세리신, 피브로인 비율과 상관없이 모두 매우 뛰어난 흡수력을 갖고 있었다. 건조와 침지 반복에 따른 형태 유지력 또한 실크 스펀지는 매우 우수하였다. 따라서, 실크 단백질을 이용한 스펀지는 성형보형물 또는 지혈솜 등의 다양한 용도로 적용이 가능할 것으로 여겨진다.
