  • Supply of ntrition-balanced feed is very important for growth of fish, especially for growth of early period of fish. Therefore, most of commercial feeds for larval and juvenile fish are relatively expensive due to high level of the several nutrients to satisfy their requirements for growth. Overfeeding larval fish may increase fish production cost because of larvae feeds high price and deteriorate water quality, eventually reduce growth of fish. (omitted)

  • Morphological differences were studied using the analysis of variance between various partial length and shell length of three populations of Saxidomus purpuratus on the Korean waters. The Relative growth equations, that is, SH-SL, SW-SL, TW-SL of S. purpuratus by sex were estimated. The analysis of variance of four morphological characters proved that each population has no sexual differences (p>0.01). But the three populations are significantly different in morphological characters (p<0.01).

  • This study was conducted to determine the biological activities of 70% ethanol extracts from rice husks of nine rice cultivars in Korea. The relative antioxidant activities of rice husk extracts were evaluated by determining DPPH, ABTS radical scavenging activity and reducing power. The contents of total polyphenol, flavonoid and r-oryzanol were measured by spectrophotometric methods. Among the extracts of rice husks, Nokmi rice husks tended to have the most effective antioxidant activities compared to other rice husk varieties. Seolgaeng rice husk extract showed anti-proliferative activity against cancer cell lines (MCF7 and NCI-H460), and Hongjinju rice husk extract significantly exhibited mitogenic activity.

  • We constructed a rock bream Oplegnathus fasciatus leukocyte cDNA library and a total of 795 expressed sequence tag (EST) clones were generated. Gene annotation procedures and homology searches of the sequenced ESTs were locally done by BLASTX for amino acid similarity comparisons. Of the 795 EST clones, 491 different ESTs showed significant homology to previously described genes while 304 ESTs were unidentified, hypothetical, or unnamed proteins. Encoding 121 different sequences were identified as putative bio-defense genes or genes associated with immune response.

  • Penaeidins은 새우류에 존재하는 항미생물성펩티드의 한 종류로서 새우의 외부 병원체에 대한 방어기작을 구성하는 중요한 인자이다. 본 연구에서는 대하 혈구세포의 cDNA library로부터 분리된 EST 클론을 분리 동정하였다. 아미노산 염기서열 분석과 계통수 분석을 통하여 본 연구에서 분리한 EST 클론이 대하의 Penaeidin 3-2 유전자와 아미노산 수준에서 동일함을 밝혔다. 대하의 Penaeidin 3-2는 signal peptides로 예상되는 19개 아미노산 잔기를 포함하여 전체 71개의 아미노산 잔기로 이루어져 있고, C-말단에는 3개의 이중황화결합을 형성할 수 있는 6개의 cysteine가 존재하였다. 대하 Penaeidin 3-2 전사체는 혈구세포, 간췌장, 근육 조직에서 발현되었으며, 특히 혈구세포에서 주로 많이 발현되었다. 흰반점바이러스의 인위감염 실험에서 바이러스 감염 후 대하 Penaeidin 3-2의 발현이 증가하였다. 이상의 결과들로부터 대하 Penaeidin 3-2가 자체 방어 작용에서 중요한 역할을 할 것으로 예상된다.

  • Various microorganisms play important roles in food fermentation, food spoilage, and agriculture. In this study, the biotype of 54 yeast and bacterial strains having high potential for utilization in food and agriculture, including Candida spp., Lactobacillus spp., and Acetobacter spp., were characterized by matrix-assisted laser desorption/ionization time-of flight mass spectrometry (MALDI-TOF MS). This characterization using a fast and robust method provides much-needed information on the selected microorganisms and will facilitate effective usage of these strains in various applications. Importantly, the unique protein profile of each microbial species obtained from this study was used to create a database of fingerprints from these species. The database was validated using microbial strains of the same species by comparing the mass spectra with the created database through pattern matching. The created reference database provides crucial information and is useful for further utilization of a large number of valuable microorganisms relevant to food and agriculture.

  • 3-Arylisoquinolin-1(2H)-ones (2) are possible bioisosteres of the $5-[4^{l}-(piperidinomethyl)phenyl]-2<$,3-dihydroimidazo[2,1-$\alpha$]isoquinoline (1) which is in clinical evaluation for the treatment of cancer. Structure-activity relationship studies of 3-arylisoquinolin-1(2H)-ones. (2) led to the synthesis of 3-arylquinolin-2(1H)-ones (3). A number of 3-phenyl substituted quinolin-2(1H)-ones were synthesized and tested for their in vitro antitumor activity against four different human tumor cell lines and 3-phenyl-N-benzyl-3,4-dihydroquinolin-2(1H)-one (12) showed the most potent activity.

  • In this study, we cultivated 115 Soritae and 86 Yakkong black soybean landraces collected from ten different locations in Korea. Then, the variations of three yield components (one-hundred seeds weight (HSW), number of seeds per pod (SPP), and yield per plant (YPP)) and three anthocyanins (cyanidin-3-O-glucoside (C-3-O-G), delphinidin-3-O-glucoside (D-3-O-G) and petunidin-3-O-glucoside (Pt-3-O-G)) were investigated according to landrace type and collection area. Both yield components and anthocyanin contents significantly varied between the soybeans demonstrating genetic differences. Soritae landraces had the highest average HSW and TAC, whereas Yakkong landraces displayed the highest average SPP irrespective of collection area. Relatively, Yakkong landraces from Gyeongsangnam-do (1697.29 mg/100 g) and Soritae landraces from Gyeonggi-do (2340.94 mg/100 g) had the highest average TAC. Principal component analysis clearly separated Soritae and Yakkong landraces. Moreover, TAC and C-3-O-G showed positive and significant associations in both Soritae (r = 0.972) and Yakkong (r = 0.885) landraces, while yield components showed negative or weak correlations with each other. Overall, ten landraces were identified as important resources owing to their high yield (>150 g/plant) and high level of TAC (>2300 mg/100g). This study could lay foundations to molecular level investigations and reinforce the use of Yakkong and Soritae landraces during cultivar development.
