  • 인각와는 백제기와의 특징이라 할 수 있으며 익산에서 가장 많이 출토되고 있다. 그 종류와 출토량 그리고 출토유적의 성격을 살펴보면 왕실과 관계 깊은 유적에서 주로 사용하였다는 것을 알 수 있다. 또한 제작기법이 같다는 것은 특정 와공집단에 의해 생산되었을 가능성이 크다. 생산시기에 대해서는 간지명인각와를 참고하였다. 그 결과 크게 무왕 즉위를 전후한 시기와 기축년(629)을 중심으로 한 7세기 제2/4반기 두 시기로 나뉘어 생산된 것으로 추정하였다. 이와 함께 왕궁리유적과 미륵사지의 창건기 수막새도 문양과 출토량 등을 검토한 결과 인각와와 같이 두 시기로 나뉘어 생산 공급되었음을 알 수 있었다. 생산배경에 대해서는 제작기법 생산시기와 함께 오부와 오항을 나타내는 인각와의 성격을 검토하였다. 무왕 주체의 조영사업에 필요한 기와생산에는 왕실만으로 그 재원을 확보할 수 없었기 때문에 오부뿐만 아니라 오항에서도 원조가 이루어졌다. 이러한 배경 하에 성립된 기와생산은 관 주도의 일원화된 체제하에서 이루어졌는데 이때 생산된 인각와의 인장을 인증 또는 검정을 위해 만든 것으로 날인 주체는 기증자도 생산자도 아닌 정해진 수량을 확인하고 날인할 수 있는 검사관으로 판단된다.

  • Mu-Guan(武冠) is a headgear of northern nomadic people's costume, Ho-Bok(胡服). It became a part of Chinese(中原) Costume through the adoption of Ho-Bok(胡服) by King Muryong(武寧王) of Kingdom of Cho(趙). Chinese(中原人) did not use it as the formal costume of high class but the Costume military or low-level classes because Chinese(中原人) reguad it as a practical costume only for low-level classes. In this process, Mu-Guan(武冠) and it's clothes had got changed. It became high in shape by an influence Hsien-pi(鮮卑族)'s headgear and became generous in it's going with clothes for Chinese(中原) Costume. It needs to attend that Mu-Guan(武冠) could be found in Koguryo(高句麗)'s mural paintings. Mu-Guan(武冠) of Koguryo(高句麗) had kept the same pattern from middle of 4C to late of 5C. Actually Koguryo(高句麗)'s Mu-Guan(武冠) was similar with Han(漢) dynasty's, but It was quite different from Qin(晉) or Wei(北魏) dynasty's which belong to same period with Koguryo(高句麗)'s. It is possible to guess at Koguryo(高句麗) advanced Mu-Guan(武冠) as their own. Koguryo(高句麗) could be aware of 'Changed Mu-Guan(武冠)'. Because there are frequent diplomatic event between Koguryo(高句麗) and Chiese Dynasties, Barbarian Dynasties. Moreover the guess have persuasion by the existence of 'Changed Mu-Guan(武冠)'in Jee-an(集安) district's mural painting as a Costume of holy person. In brief, It could be noticed that Koguryo(高句麗)'s Mu-Guan(武冠) is distinguished from Chinese and Barbarian dynasties' and Koguryo(高句麗) advanced Mu-Guan(武冠) in their own style.

  • The dibucaine number (DN) was determined for serum cholinesterase (EC 3.1.1.8, SChE) in plasma samples. The ones with a DN of 79-82 were used, because they had the "usual" SChE variant. The enzyme was assayed colorimetrically by the reaction of 5,5'-dithiobis-[2-nitrobenzoic acid] (DTNB) with the free sulfhydryl groups of thiocholine that were produced by the enzyme reaction with butrylthiocholine (BuTch) or acetylthiocholine (AcTch) substrates, and measured at 412 nm. Dibucaine, a quaternary ammonium compound, inhibited SChE to a minimum within 2 min in a reversible manner. The inhibition was very potent. It had an $IC_{50}$ of $5.3\;{\mu}M$ with BuTch or $3.8\;{\mu}M$ with AcTch. The inhibition was competitive with respect to BuTch with a $K_i$ of $1.3\;{\mu}M$ and a linear-mixed type (competitive/noncompetitive) with respect to AcTch with inhibition constants, $K_i$ and $K_I$ of 0.66 and $2.5\;{\mu}M$, respectively. Dibucaine possesses a butoxy side chain that is similar to the butryl group of BuTch and longer by an ethylene group from AcTch. This may account for the difference in inhibition behavior. It may also suggest the existence of an additional binding site, other than the anionic binding site, and of a hydrophobic nature.

  • Babesia spp. were detected from 4 asymptomatic pukus captured on a game ranch in central Zambia in October 2008. Blood smears were examined in 4 species of aymptomatic free-ranging antelopes, namely the puku (Kobus vordanii), reedbuck (Redunca arundinum), bushbuck (Tragelaphus sylvaticus), and kudu (Tragelaphus strepsiceros), and showed the presence of Babesia parasites only in the puku. In the puku, the prevalence of babesiosis was estimated at 33.3% (n=12), while the overall prevalence in all examined animals was 8.5% (n=47). The parasites showed morphological characteristics of paired ring-like stages with the length varying between $1.61{\mu}m$ and $3.02{\mu}m$ ($mean=2.12{\mu}m$, n=27; $SD=0.76{\mu}m$). Both the infected and non-infected pukus showed good body condition scores (BCS), while the dominant tick species detected from all animals were Rhipicephalus appendiculatus, Rhipicephalus spp., and Boophilus spp. To our knowledge this is the first report of Babesia spp. infection in pukus in Zambia. These findings suggest that wildlife could play an important role in the epidemiology of babesiosis in Zambia.

  • Background: Chronic myeloid leukemia (CML) is a myeloproliferative disorder of pluripotent stem cells, caused by reciprocal translocation between the long arms of chromosomes 9 and 22, t(9;22)(q34;q11), known as the Philadelphia chromosome. Materials and Methods: A total of 51 CML patients were recruited in this study. Complete blood counts of all CML patients were performed to find out their total leukocytes, hemoglobin and platelets. FISH was performed for the detection of BCR-ABL fusion and cryptogenic tests using bone marrow samples were performed for the conformation of Ph (9;22)(q34;q11) and variant translocation mechanisms. Results: In cytogenetic analysis we observed that out of 51 CML patients 40 (88.9%) were Ph positive and 4 (8.88%) had Ph negative chromosomes. Mean values of WBC 134.5 $10^3/{\mu}l$, hemoglobin 10.44 mg/dl, and platelets 288.6 $10^3/{\mu}l$ were observed in this study. Conclusions: In this study, Ph positive translocation between chromosome (9:22)(q34;q11) were observed in 40 (88.9%) CML patients.

  • Objective: The aims of this study were to select one strain of Lactobacillus plantarum (L. plantarum) for a potential indigenous safe starter culture with low level antibiotic resistant and low biogenic amine production and evaluate its effect on biogenic amines reduction in Moo som. Methods: Three strains of indigenous L. plantarum starter culture (KL101, KL102, and KL103) were selected based on their safety including antibiotic resistance and decarboxylase activity, and fermentation property as compared with a commercial starter culture (L. plantarum TISIR543). Subsequently, the effect of the selected indigenous safe starter culture on biogenic amines formation during Moo som fermentation was studied. Results: KL102 and TISIR 543 were susceptible to penicillin G, tetracycline, chloramphenicol, erythromycin, gentamycin, streptomycin, vancomycin, ciprofloxacin and trimethoprim (MIC90 ranging from 0.25 to $4{\mu}g/mL$). All strains were negative amino acid-decarboxylase for lysis of biogenic amines in screening medium. For fermentation in Moo som broth, a relatively high maximum growth rate of KL102 and TISIR543 resulted in a generation time than in the other strains (p<0.05). These strain counts were constant during the end of fermentation. Similarly, KL102 or TISIR543 addition supported increases of lactic acid bacterial count and total acidity in Moo som fermentation. For biogenic amine reduction, tyramine, putrescine, histamine and spermine contents in Moo som decreased significantly by the addition KL102 during 1 d of fermentation (p<0.05). In final product, histamine, spermine and tryptamine contents in Moo som inoculated with KL102 were lower amount those with TISIR543 (p<0.05). Conclusion: KL102 was a suitable starter culture to reduce the biogenic amine formation in Moo som.
