  • Electrophoretic method is and morphometric analysis were used to examine genetic and phenetic variation among 16 populations of Rhabdophis tigrina and to clarify the subspecific status of R.t.tigrina and R.t. lateralis in Korea. The degree of genic variation based on 23 presume loci was moderate and was similar to those found for other vertebrates. Interpopulation levels of genic differentiation were slight for all populations studied and overall genetic similarities were =0.970. The number of ventral and subcaudal scales showed clinal variation with increasing tendency in numbers toward south . Discriminant function analysis based on six morphometric characters revealed that there were no morphometric differentiation between two subspecies, therefore it was concluded that they were same taxon and R.t. lateralis (Berthold, 1859) should be treated as synonym of R. t. tigrina(Boie, 1826)

  • The purpose of this study was to understand the evolutionary relationships between fish and other vertebrates which had DNA with the genetic defects in homoglobin expression, with comparison to the nucleotide homologies of the ${\beta}$-globin genes. The predicted amino acid sequence from carp ${\beta}$-globin gene was compared with those of other vertebrates from the published data. The nucleotide homologies of the predicted amino acid sequence from the carp ${\beta}$-globin gene with those of goldfish and mirror carp were high, and the rates were 97.3% and 93.9%, respectively. On the other hand, with the previously reported ${\beta}$-globins of goat, frog, human, rat, goose, chicken, and duck, it showed low homology ranging from 45.9 to 58.1%. The carp ${\beta}$-globin has one inserted amino acid residue, which was also found in other fish ${\beta}$globin, but not in other vertebrate ${\beta}$-globins.

  • 국내 육성 품종 JW07-190, JW07-192과 일본산 도입 품종 Meiryoku (MR), Ryoufuu (RF), Yamanoibuki (YI) 대해서 80% 메탄올 추출물을 공시 재료로 ESR을 이용하여 항산화 효능을 평가하였다. 국내 육성 품종인 JW07-192에서 DPPH radical, alkyl radical, hydroxyl radical에 대해 비교적 높은 radical 소거능을 보였고, 모든 녹차 품종에서 강력한 DPPH radical 소거능을 보였다. 전체적으로, 국내 육성 품종인 JW07-192가 일본 도입 품종과 비교하였을 때 더 좋은 항산화 효능을 나타내었다. 총 폴리페놀 함량은 국내 육성 계통인 JW07-192가 $431.57{\pm}28.45\;mg/g$로 가장 높은 함량을 나타냈고, 플라보노이드 함량은 도입 품종인 YI가 $313.44{\pm}6.31$로 가장 높은 함량을 보였다.

  • The fatty acid composition of the oil in the rapeseed grown by spring and autumn planting were determined by gas liquid phase chromatography. Erucic acid content of the rapeseed oil grown by autumn planting was higher than that produced by spring planting, but the contents of oleic acid and linoleic acid were lower in autumn planting than those in spring planting. There was significant difference at 1% level between seasonal plantings. The reasons for the different fatty acid compositions were the low integrated temperature, the high amount of precipitation and the short hours of sunshine during the maturing period in autumn planting.

Intra-, Inter-specific Variation of Korean Rana (Amphibia: Ranidae) Based on the Partial Sequence of Mitochondrial 16S rDNA (미토콘드리아 16S rDNA부분 염기서열을 이용한 한국산 개구리 속(Amphibia: Ranidae)의 종간, 종내 변이에 대한 연구)

  • In order to clarify intra-and inter-specific variation of Korean Rana species, the partial DNA sequences of mitochondrial 16S rDNA gene were determined from 6 Korean and 1 Japanese Rana species, DNA sequences from Korean and Japanese species were comparison-analysed within, and also with the sequences from three species of Japanese brown frogs. DNA similarities were calculated as 91.3∼97.3% among brown frog (R. amurensis coreana, R. dybowskii and R. huanrenensis), as 96.11∼97.26% among pond frogs (R. nigromaculata and R. planeyi chosenica). Genetic distance of pond frog and wrinkle fyog (R. rugosa) were near than that of pond frog and brown frog. Two clusters were formed brown frogs and the other group by neigh-bor-joining and maximum-likelihood analysis, also the populations of R. nigromaculata were well distinguished between Korean peninsula and Korean island. But result from maximum-likelihood analysis slightly differed from neighbor-joining to cluster of R. rugosa. Further analyses for their population will be necessary to study the phylogenetic status.

  • 해양자원으로부터 상업적인 가치를 지니는 천연물질들을 획득하는 것은 일본의 수산업에 있어서 매우 중요하다. 일본에서는 해양자원의 부산물을 이용하여 다양하고 많은 상업적인 제품들을 성공적으로 개발하고 있다. 키틴, 키토산, 어유, 액정(liquid crystal), 프로타민(protamine, 식품에 향균제로 사용되며 물고기의 고환으로부터 얻음), 어류양식장에서 사용하는 성장호르몬, 해양생물로부터 추출하는 몇가지 의약품 등이 대표적인 예이다.
