  • 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.

  • Miniature inverted transposable elements (MITEs) are abundant genomic components in plant including rice. MITE-transposon display (MITE-TD) is an Amplified Fragment Length Polymorphism (AFLP)-related technique based on MITE sequence. In this study, we used the MITE-AFLP for the analysis of diversity and relation-ship of the 114 japonica accessions. Of the several MITEs, the mPing family was applied to detect polymorphisms based on PCR amplification. The BfaI adaptor primer and the specific primer derived from mPing terminal inverted repeat (TIR) region were used to PCR amplification of 114 accessions. Nine primer pairs produced a total of 160 polymorphic bands. PIC values of the polymorphic bands generated by nine primer pairs ranged from 0.269 (BfaI + ACT) to 0.426 (BfaI + T). Each accession revealed a distinct fingerprint with two primer combinations, BfaI + G and BfaI + C. Cluster analysis using marker-based genetic similarity classified 114 accessions into five groups. MITE-AFLP markers were genetically mapped using a population of 80 BILs (BC1F7) derived from a cross between the rice accessions, Milyang 23 and Hapcheonaengmi 3. Eight of the markers produced with the primer pair BfaI + 0 were mapped on chromosomes 1, 2, 4, 5, 7, and 9. Considering that one MITE-AFLP marker on chromosome 7 was tightly linked to the Rc gene, the MITE-AFLP markers will be useful for gene tagging and molecular cloning.
