In order to investigate the protein binding characteristics of braD6n and hematoxy6n to bovine semm albumin (BSA), the fluorescence probe method was adopted. Brazilin and hematoxy6n showed strong binding affinity for BSA. It was also confirmed that hematoxy6n was bound to BSA stronger than braDlin. The association constants were decreased by the elevation of concentrations of brazilin and hematoxylin. It might be due to the complex formation of the probe and both compounds or the interaction between the probe-protein complex and both compounds. The bindings between both compounds and BSA were dependent on pH and ionic strength. It seems that electrostatic force as weD as hydrophobic force is involved in the binding of braD6n and bematoxylin to BSA.

This study was conducted to compare the characteristics of fish distribution according to sand type stream and cobble type stream the 4 stream selected every season. The collected Korea endemic species during the survey period were 24, including Acheilognathus gracilis. Dominant species of Hongcheon stream and Muju Namdae stream was Zacco koreanus, each accounting for 39.9% and 28.4% in order, and dominant species in Yanghwa stream was Rhodeus notatus, 13.6%, and those in Gap stream was Z. platypus, by 26.0%. As a result of community analysis, dominant index was 0.27~0.63, diversity index was 1.92~2.67, evenness index was 0.6~0.79, richness index was 3.09~3.53, and dominant index was the highest in Hongcheon stream, and the indices of diversity, evenness and richness were the highest in Yanghwa stream. As a result of tolerance guild analysis, Hongcheon stream and Muju Namdae stream with a variety of substrates accounted for relatively higher rate by 50.1% and 46.4% in sensitive species respectively, and Yanghwa stream and Gap stream with greater sand substrates had 0.5% and 5.3% scarce rate of sensitive species. As a result of similarity analysis using the species, population and substrate structures of the fisheries appeared in each stream, cobble type streams such as Hongcheon stream and Muju Namdae stream were the most similar by 50.4% in species and population, 95.2% in bed structure. As a result of IBI analysis, Hongcheon stream and Muju Namdae stream appeared as 'Class A,' Yanhwa stream and Gap stream as 'Class B' and the two groups of cobble type stream and sand type stream were divided as a result of principal components analysis.
