  • To elucidate the effect of dorsal acupoints for canine electroacupuncture anesthesia, mongrel dogs(6 heads: 2.6-10.5kg, 3 males and 3 females) were used. After needling perpendicularly to Tian-Ping(GV-5) and Bai-Hui(GV-20), the electrodes were connected with positive to Tian-Ping and negative to Bi-hui, respectively using with veterinary electroacupuncture apparatus(TEC AM-3000). The electric conditions were 2-4V and 30 Hz. The pain of body surface was checked by hemostatic forceps. The effect of electroacupuncture andesthesia was appreciated by application of laparotomy(2 heads), ear trimming and tail amputation(1 head), castration(2 heads) and enterotomy(1 head), respectively. Induction time, clinical findings and operation findings were investigated under the electroacupuncture anesthesia. The induction time of electroacupuncture anesthesia was very rapid, approximately 1 minute and the pain of body surface including the extremities was not detected. As for clinical findings during electroacupuncture anesthesia, consciousness was evident, pupil reflex was weak and blepharoreaction was existed. As for operation findings, pain was not detected during incision and suture, and bleeding was relatively small volume. The grade of electroacupuncture anesthesia was excellent in all cases applied with ear trimming and tail amputation, laparatomy, castration and enterotomy. Considering above all findings, it was thought that electroacupuncture stimulation at Tian-Ping and Bai-hui examined in the present study induced excellent electroacupuncture anesthesia for dogs.

  • Manganese(III) 5-(4-carboxyphenyl)-10,15,20-triphenyl porphyrin chloride (Mn(TCPP)Cl) was grafted through amide bond on silica zeolite Y (HY), zeolite beta ($H{\beta}$) and hexagonal mesoporous silica (HMS). XRD, ICP-AES, $N_2$ physisorption, SEM, TEM, FTIR and thermal analysis were employed to analyse these novel heterogeneous materials. These silica supported catalysts were shown to be used for epoxidation and good shape selectivity was observed. The effect of support structure on catalytic performance was also discussed. The catalytic activity remained when the catalysts were recycled five times. The energy changes about epoxidation of alkenes by $NaIO_4$ and $H_2O_2$ were also computationally calculated to explain the different catalytic efficiency.

  • 1. 자포니카 벼 114 계통에 대해 다양성과 근연관계를 확인하고자 MITE 중에서 mPing family를 이용하여 MITE-TD 기법으로 분석하여 품종간의 다양성 정도를 산출한 결과 마커들의 PIC 값이 $0.293{\sim}0.499$ 범위로 나타났다. 2. 두 개의 mPing primer와 selective primer인 BfaI+G 와 BfaI+C의 조합을 이용하였을 때, 공시계통인 114개의 자포니카 벼 전체를 구분할 수 있었다. 3. NTSYS-pc를 이용한 근연관계 분석 결과, 유사계수의 범위는 0.802에서 부터 0.081까지였고, 자포니카 벼 114 품종은 크게 5 개의 그룹으로 분류되었다. 4. 8 개의 MITE-AFLP marker 연관분석을 밀양 23호/합천앵미 3호 조합 RIL을 이용하여 실시한 결과, 이들은 염색체 l번, 2번, 4번, 5번, 7번 그리고 9번에 각각 위치함을 확인하였다.
