In this study, we investigated the partition property of pyrene onto cell membrane using synthetic membrane vesicles consisted ofseveral phospholipids and the effect of natural organic matters (NOM) on the partition. Membrane fluidity and membrane phaseaffected partition coefficient (Pmw) of pyrene onto the membrane. Pmw was larger for the liposome in liquid crystalline phase > inripple phase > in gel phase. Pyrene did not undergo the steric interfere in partition onto the membrane used in this study. Negativecharge of the membrane did not affect Pmw of pyrene. Suwannee River Natural Organic Matter (NOM) and Nordic fulvic acidaffected the partition of pyrene onto the TRANSILmembrane. The reason was confirmed that NOM associated pyrene did notpartition onto the membrane. Low molecular weigh fraction of SRNOM had strong effect on the partition as much as high molecularweigh fraction. From calorimetrical analysis, it was found that SRNOM did not affect the fluidity of the dimyristoy-lphosphatidylcholine (DMPC) membrane.

This study analyzed the effects of reducing nutrients by managing pollution sources from cultivated area and livestock area in order to improve the water quality of the Lake Paldang Basin. To predict the effects of reducing nutrients in the Lake Paldang Basin, water pollution sources were first analyzed and possible scenarios to reduce the sources were selected accordingly. Using the basin environmental database, water flow rates, and TN and TP concentrations were simulated based on the Soil and Water Assessment Tool (SWAT) model. Model evaluation indices were calculated through the calibration and validation of water flow rates, and TN and TP concentrations, and they were found that simulation values reflected measurement values well, and that it was possible to evaluate the Lake Paldang Basin both qualitatively and quantitatively. In the case of Scenario 3 in which a measure to reduce pollution sources from both cultivated area and livestock area was applied together, the concentrations of TN and TP were reduced by 29.6% and 28.6% respectively. It is believed to be important to improve water quality by managing pollution sources from both cultivated area and livestock area particularly in area like the Lake Paldang Basin where agricultural and livestock production activities are actively conducted. The results of analyzing the effects of reducing nutrients in the Lake Paldang Basin showed that the concentrations of TN and TP were reduced to 3.42 mg/L and 0.167 mg/L respectively in Scenario 3. It was found that measures to reduce pollution sources from cultivated area and livestock area were effective for improving the water quality of the Lake Paldang Basin. It is also believed that reducing the amount of fertilizer applied to cultivated area is effective for managing nutrients, and that it is necessary to expand environmental infrastructure to reduce pollution sources from livestock area.

We previously reported that chicken collagen hydrolysate (CCH) has strong angiotensin I converting enzyme (ACE) inhibitory activity and antihypertensive effects on spontaneously hypertensive rats. Here, we investigated the chronic therapy effects of CCH on blood pressure and vascular relaxation in a cardiovascular damage model of Wistar-Kyoto rats induced by N-nitro-l-arginine methyl ester (l-NAME). Following co-treatment with CCH for 4 weeks, the increment of systolic blood pressure was suppressed significantly. At 8 weeks, the vasorelaxation of thoracic aorta increased significantly, and cardiovascular damage was ameliorated. The concentration of soluble intercellular adhesion molecule-1 (ICAM-1) in blood was reduced significantly by long-term administration of CCH, whereas the nitric oxide concentration was increased significantly at 1 hour post-treatment. The results suggest that beneficial effects of CCH result from antihypertensive function, but also from inhibition of cardiovascular damage to the endothelial cells via its ACE inhibitory activity and regulation of nitric oxide and ICAM-1, which suggests that CCH may be useful as a medicinal food for patients with cardiovascular disease.
