  • 본 연구에서는 용매열합성법을 이용하여 용액의 서로 다른 pH와 용매 조건에서 4종의 수산화인회석을 합성하였다. 합성된 샘플의 결정성과 형태를 X-선 회절 분석과, 투과형전자현미경을 통하여 분석하였다. 4종의 수산화인회석은 pH와 용매 조건에 관계없이 거의 유사한 형태의 XRD 패턴을 보여 주었다. 그러나 형태는 순수한 물을 용매를 사용하였을 경우 염기 조건에서 합성한 수산화인회석이 [001] 방향으로 결정이 성장한 형태를 보였으며, 또한 순수한 물에 메탄올과 에탄올이 첨가한 조건에서 합성한 수산화인회석은 [001] 방향으로 더욱더 결정이 성장한 형태를 보였다.

  • As mentioned above, I have acquired some valuable results about medical treatments with acupuncture for "Trigeminal neuralgia" after studying oriental medical books. 1. The course of medical treatments with acupuncture was, first of all, applying general ones, and then, assisting ones based on occuring area of pain and the cause. 2. For general treatments, "Chok-yangmyong-Wi-Kyong", distributed widely on the face, was used in great numbers. The order, according to the number of using times, of spots for acupuncture was Ha-kwan(11 times), Hap-kok(10), Chan-juk(7), Hyop-geo, Tae-yang, Sa-baek(individually 6). 3. For assisting treaments based on occuring area of the pain, spots of the Kyong-rak, passing through occuring area of the pain, and Kyong-woe-ki-hyol were used in great numbers. 4. The order was O-je, Chan-juk, Yang-baek(individually 8), Tae-yang(5) for the pain of first branch of the trigeminal nerve; Sa-baek(12), Kwan-ryo(6), Go-ryo(5) for the pain of second one; and Hyop-geo, Ha-kwan(individually 6), Dae-young, Hyop-seung-jang(individually 5). Seung-jang(4). 5. For assisting treatments based on the cause, "One-hyol(原穴)", "Rak-hyol(絡穴)" and "5-soohyol(五輸穴)" were used in great numbers. 6. The order was Pung-ji(10), Hap-kok(9), Woe-kwan(5) for "Woe-Kam(外感)"; Nae-jong(12), Tae-chung(10), Chok-sam-ri(7) for "Kan-Wi-Hwa-Seung(肝胃火升)"; Tae-gue(7), Sam-um-kyo, Pung-ji(individually 2) for "Ho-Hwa-Sang-Seung(虛火上升)"; Pung-ryung(4) for "Pung Dam-Jo-R ak (風痰阻絡)"; Kyok-su(2) for "Ki-Che-Hyol-Ho(氣滯血虛)".

  • Objectives : In this study, we investigated anti-allergic effect of Okbyeongpungsan-Hap-Changijasan (KOB01) in allergic rhinitis(AR) experimental animals and mast cells. Methods : The potential anti-allergic effect of KOB01 was investigated in a rat model of compound 48/80-induced systemic anaphylactic shock and a mouse of ovalbumin(OVA)-induced AR, and human mast cell line, HMC-1 culture. Each animals were divided into four groups: normal, control, KOB01-treated(100 and 200 mg/kg) and anti-histamine drug, dosodium cromoglycate (DSCG)-treated(50 mg/kg). Animals were orally treated with KOB01 and DSCG and intraperitoneally injected with compound 48/80($10\;{\mu}g/kg$) or sensitized with 0.1% OVA. The mortality and serum histamine levels were measured in compound 48/80-induced anaphylatic rats. The histological changes in nasal mucosa were investigated in OVA-induced AR mice. Also, mast cell degranulation was observed in compound 48/80-stimulated HMC-1 cells. Results : KOB01 increased mortality and significantly decreased serum histamine levels in compound 48/80-induced anaphylatic rats. The abnormal histological changes such as expansion of grandular cells and hypertrophy of epithelium in nasal mucosa of OVA-induced AR mice was improved by KOB01 treatment nearby a normal group. Therefore, KOB01 inhibited compound 48/80-induced degranulation in HMC-1 cells. Conclusions : These results indicate that KOB01 decrease allergic response through suppressing the mast cell activation in AR and suggest a potential role for KOB01 as a source of anti-allergic agents for use in allergic disorders including of AR.

  • This study is designed to compare the effect of a needle with the magnet on body. We took the skin temperature of the belly with digital infrared thermographic imaging while we sticked needle and apply magnets on L14. We made experiments on 40 healthy male volunteers for one month. We classified control group not acupuncture or magnet adhering(CON). acupuncture group on left and right L14(LA). and the permanent magnet group adhering to left and right(LM). And LM is divided into S-polar permanent magnet group(LMS) and N-polar permanent magnet group adhering to left and right L14(LMN). When we observed that temperature changed with time, the skin temperature of th belly in CON descended significantly but LM, LMS and LMN is not changed significantly. As mentioned above. we observed that the needles on L14 affected the change of temperature on the belly, and conjectured that the appliance of magnets had the same results. If the mechanism depends on the meridian of body and energy. we suppose that the appliance of magnets and needles has same effects.

  • A porous $Al_2O_3$, scaffold coated with tricalcium phosphate(TCP) was fabricated by replica method using polyurethane(PU) foam as a fugitive material. Successive coatings of $Al_2O_3$ and hydroxyapatite(HAp) were applied via dip coating onto polyurethane foam, which has a slender and well interconnected network. A porous structure was obtained after sequentially burning out the foam and then sintering at $1500^{\circ}C$. The HAp phase was changed to TCP phase at high temperature. The scaffold showed excellent interconnected porosity with pore sizes ranging from $300{\sim}700{\mu}m$ in diameter. The inherent well interconnected structural feature of PU foam remained intact in the fabricated porous scaffold, where the PU foam material was entirely replaced by $Al_2O_3$ and TCP through a consecutive layering process. Thickness of the $Al_2O_3$ base and the TCP coating was about $7{\sim}10{\mu}m$ each. The TCP coating was homogeneously dispersed on the surface of the $Al_2O_3$ scaffold.

  • Objectives : Ulcerative colitis and Crohn's disease are chronic inflammatory disease of the gastrointestinal tract was identified mainly for diarrhea, stomachache, hemafecia. The source and pathologic mechanism about ulcerative colitis and crohn's disease are still unknown but stress, infection, a genetic factor, environmental factors etc. may be the cause of chronic inflammatory disease of the gastrointestinal tract recently. The purpose of the present study is to evaluate the effects of herbal acupuncture with Artemisiae Argyi for the treatment to intestinal disease in the rat with 2, 4, 6 - trinitrobenzenesulfonic acid (TNBS) induced colitis. Methods : Artemisiae Argyi Herbal acupunctures were infected in HapGok (LI4) which is used to treat for intestinal disease in clinic. All animals were subjected to the injection of saline (300 ${\mu}l$, 500 ${\mu}l$) for a study control and TNBS (300 ${\mu}l$, 500 ${\mu}l$) into the lumen of the colon, 8cm proximal to the anus through the intestine. Artemisiae Agryi' Herbal (20 mg/ml, 0.4 ml) acupunctures were injected to the LI4 (both hands) at the secondary injection time of TNBS in rats. And body weight, RBC count, WBC count, total protein, Paw edema rate, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels were observed to study the effects of Artemisiae Argyi' Herbal acupuncture in HapGok (Ll4). Results : Artemisiae Argyi' Herbal acupuncture in HapGok (Ll4) on TNBS-induced colitis inhibit the body weight lose rate but not RBC and WBC count. Furthermore, it inhibited the reduction of total protein concentration, paw edema, rate of protein leakage into CMC-pouch fluid, IgG levels and IgM levels. Conclusions : Herbal acupuncture with Artemisiae Argyi helps recover the TNBS-induced colonic damage and may be an important method for treatment of the colitis.

  • Three different kinds of hydroxyapatites (HAPs) having different sizes and compositions are prepared by hydrothermal and molten salt syntheses. Using the ion exchange reactions, ruthenium ions are incorporated on the surface of HAPs. The crystallinity, morphology and ruthenium contents are investigated by XRD, SEM, TEM and ICP. We found that smaller size of HAP having large amounts of ruthenium under ion exchange reaction shows higher catalytic activity for aerobic oxidation of alcohols.
