Yangkyuksanhoa-tang is freguentally used for cerebrovascular accident(CVA). The present study was performed to investigate the effect of Yangkyuksanhoa-tang on the perivascular immunoreactive nerve fiber of the basilar arte교 after experimentally induced subarachnoid hemorrhage(SAH). Sprague Dawley rats weighing between 350-400g were used. The SAH induced by injection of the fresh autologus heart blood (0.3-0.4ml) into the cisterna magna through the posterior atlanto-occipital membrane. Snmple group was given a 3.3 ㎖/㎏/day of Yangkyuksanhoa-tang extracts for 2 days after SAH. The experimental animals divided into 48hrs after SAH. The changes of perivascular immunoreactive nerve fiber was examined by using indirect immunofluorescence method. The meshlike perivascular nerve fiber appeared in the basilar artery of normal rats. In basilar artery of SAH elicitated rat, the distribution of calcitonin gene-related peptide(CGRP)-immunoreactivity(IR) and vasoactive intestinal polypeptide(VIP)-IR of the perivascular nerve fiber were remarkably diminished, also dopamine beta hydroxylase(DBH)-IR, neuropeptide Y(NPY)-IR and serotonin-IR were diminished. In SAH elicitated rat with Yangkyuksanhoa-tang treatment, the CGRP-IR and VTP-IR degree were repaired as well as normal rat's, but DBH-IR, NPY-IR and serotonin-IR had no changes. These results provide the basic data to investigate the effect of Yangkyuksanhoa-tang on the vasospasm after SAH.

李東垣,辛吉祚,李源哲 동국대학교 한의학연구소 1995 東國韓醫學硏究所論文集 Vol.4 No.-

This study was done in order to investigate the treatment of occidental and oriental medicine on dementia(mainly senile dementia and cerobrovascular dementia). The results were as fellows ; 1. Dementia must treat a direct causes, but uncountable dementia(senile dementia) and cerobrovascular dementia can't treat at present. 2. Sciopsychological treatment in very important in dementia patient : maintance of appropriate stlmulation psychological rest, physical examination, dietary cure and safety device is needed. On secondary mental disorder antipsychotics, anxiolytics and antidepressants have to proscribe properly. 3. Treatments of Senile dementia(uncountable cerebral degenerative disease) prescribed hydergine which is peripheral vasodilator and physostigmine which increase cholinergic activity (of brain, but this have slight effort on some patients. On treatments of cerobrovascular dementia, the medication that improved the cell metabolism and circulation of brain, this improved only a subjective symptom, but isn't foundamental treatment. 4. A tonic medicine is used basically, the methods are as folllows. 1) Kenwihwadam(建胃化痰) - Sesimtang(洗心湯) 2) Bosiniksu(補腎益髓) - Hwansodan(還少丹) 3) Bosimiksin(補心益腎) -- Gyuibitang(歸脾湯), Singyuo(神交湯) 4) Boheoansin(補虛安神) - Cilbokem(七福飮), sanggitang(生氣湯) 5) geoeohwalhyel(祛瘀活血) -tonggyuhwalhyeltang(通竅活血湯). 5. Acupuncture therapy on dementia used follow acupuncture point : Yamen(啞門 GV15), Laokung(勞宮 HC8), Tsusanli(足三里 ST36), Shenshu(腎兪 BL23), Tachui(大?? GVl4), Chiuwei(鳩尾 CV15).

Swaging에 의한 Autofrettage 加工의 有限要素解析

李澤淳,金東燮,李輝遠 영남대학교 공업기술연구소 1984 연구보고 Vol.12 No.1

Elastic-Plastic stress analysis has been carried out on an auto-frettage processed cylinder by mechanical push swaging. The analysis using finite element method was based on the incremental stress-strain relationship at the von-Mises yielding criterion and Prandtl-Reuss hypothesis in a axially symmetric plain stress condition. By this method, not only permanent enlargement of inner bore diameter but also residual stress distribution was calculated as a function of mandrel diameter. In consequence, enlargement of an autofrettage processed cylinder has good agreement between theoretical and experimental results. Thus, in autofrettage process the bore size and residual stress can be predicated using this method.

Erwina carotovora는 人蔘엑기스가 1% 添加된 群에서 24時間까지 持續的인 增殖을 보였으나, 1%미만의 人蔘엑기스 添加群에서는 培養 18時間後에는 增殖이 靜止된 狀態를 나타냈다. 2. Staphylocococcus aureus는 人蔘엑기스의 添加量이 增加함에 따라 24時間까지 持續的으로 菌의增殖이 促進되었다. 3. Escherichia coli는 人蔘엑기스 添加濃度 1%群에서 현저히 增殖되었으나, 1%미만의 人蔘엑기스 添加群은 대조군과 비슷한 증식을 보였다. 4. Salmonella paratyphi A와 Salmonella paratyphi C및 Salmonella typhi는 人蔘엑기스 添加群添加群에서 다소 增殖이 增加되었고, Salmonella paratyphi B는 1% 人蔘인삼엑기스 添加群에서 24時間까지 持續的으로 현저한 增殖의 促進을 보였다. 5. Shigella boydii 와 Shigella flexneri 및 Shigella sonnei는 人蔘엑기스의 濃度나 時間에 많은 影響을 받지 않았으나, Shigella dysentriae는 1% 人蔘엑기스 添加群에서 24시간까지 持續的으로 현저한 增殖의 促進을 보였으며, 0.1% 人蔘엑기스添加群에서는 모두 억제되었다. 6. 嫌氣性細菌에서 Peptococcus magnus와 Peptostreptococcus anaerobius는 人蔘엑기스 添加群에서 細菌增殖이 낮았고 Clostridium perfingens는 고농도 人蔘엑기스 添加群에서 增殖이 增加한 반면, Clostridium difficile은 低濃度 人蔘엑기스 添加群에서 增殖의 促進을 보였으며, Bacteroides fragilis는 人蔘엑기스 添加群에서 增殖의 低下를 보였으나, Bacteroides thetaiotaomicron은 人蔘엑기스 添加群에서 增殖이 促進되었다. The present study was carried out to look at the effect of different concentration of added ginseng (pnax ginseng C.A. Meyer) extract on the growth of microorganism such as Erwinia carotovora, Staghylococcus, Escherichia coli, Salmonella spp, Shigella spp, Pepeptostreptococcus anaerobius, Clostridium perfringens, C. difficile, Bacteroides fragilis and B. thetaiotaomicron. 1. Erwinia carotovora on 1% ginseng extract showed a continuous proliferation during 24 hrs while that on less than 1% ginseing extract showed a suspended growth state after 18 hrs. 2. Straphylococcus aureus promoted continuously until 24hrs according to increase of added ginseng extract. 3. Escherichia coli promoted tis proliferation in ginseng extract group of 1%, but was similar to control group in ginseng extract group under 1%. 4. Salmonella typhi, S. paratyphi A and S. phratyphi C were somewhat increased group added ginseng extract and S. paratyphi B showed markedly durable proliferation from 1 to 24 hrs in ginseng extract group of 1%. 5. Shigella boydii, S. flexneri and S. sonnei were not nearly influen concentartion of ginseng extract and regular times, but S. dysentriae promoted-remarkable proliferation from 1 to 24 hrs in ginseng extract group of 1%. They were all inhibition in ginseng extract group of 0.1%. 6. peptococcus magnus and peptostreptococcus anaerobius showed a decreased proliferation in added ginseng group and Clostridium perfrigens showed a increased proliferation in high concentraction of added ginseng group. C. difficile showed a increased proliferation in low concentration of added ginseng group and Bacteroides fragilis showed a decreased proliferation in added ginseng group. B. thetaiotaomicron was promoted in added ginseng group according to increase of added amount of ginseng extract.

솔-젤공정에 의해 기공보정된 한외알루미나 여과막의 기체투과 특성평가

조원준,정은정,이진휘,서성조,서동호 서울産業大學校 1997 논문집 Vol.45 No.1

서로 다른 입자크기의 3층구조를 갖는 튜브형태의 한외알루미나 분리막은, 일반적으로 제조공정중 분리층에 결손부분이 발생하기 때문에 낮은 선택도 및 제거율을 보인다. 이와같은 결손부분을 보정 하고 보정전, 후의 분리막에 대한 기체장치에 의한 투과도(permeability) 및 선택도(selectivity)를 측정하였다. Colloidal silica 솔의 deposition에 기인하여 기체 투과율의 감소가 60%였다. 한외알루미나 여과막의 보정에 있어서 습도조절에 의한 선택적 적심법은 비록 deposition에 의한 문제점을 내포하고 있으나, 기체분리에서도 효과적인 방법이다. The 3-layer tubular type alumina membrane consisting of different pore size shows the decreased selectivity and rejection because of cracks in the separation layer generally occurred during the manufacturing process. For the comparing of native and modified membranes, the modified membranes were tested by permeability by gas equipments, selectivity for the gases after caulking. The permeabilities are decreased 60% for the gas caused by deposition of colloidal silica sol after caulking. In conclusion, the Alternative Wetting Method by humidity control had the effect for the modification of ultrafiltration alumina membrane for separation of gases, though having problem of deposition.
