The effect of Profenofos on GPx activities and on the co ntents of GSH and CAR in Phaeodactylum tricornutum and Platymonas helgolan dica were studied. The results indicate that the GPx activities of two species of microalgae declined, and the contents of glutathione and carotinoid of algal c ells decreased under high concentration of Profenofos.

摘 要 实验以三角褐指藻和青岛大扁藻为材料，进行了丙溴磷农药对海洋微藻的抗氧化防御系统成份— GPx 活性和GSH、CAR含量的影响研究，结果表明，在丙溴磷胁迫下，微藻的GPx活性呈现下降趋势，GSH和CAR含量也表现为下降趋势，并且胁迫的时间越长、胁迫的强度越大它们下降的幅度也越大。

Bis(1,2,3,4-tetrahydroisoquinoline-2-ylmethyl) HBr salt (K2) guest has been synthesized from 1,2,3,4- tetrahydroisoquinoline and ethylenedibromide. The self-assembly interaction models of cucurbit[8]uril (Q[8]) with this synthetic guest have been investigated by using 1H NMR technique, single crystal X-ray diffraction determination and theoretic calculation method.
