为了了解太平洋牡蛎的生理适应策略，将太平洋牡蛎暴露于不同浓度的多环芳烃(PAHs)中。在50亩克L(-1)中，牡蛎起初保持与对照组相似的代谢速度。然后，如果暴露时间延长，牡蛎往往会减少能量摄入量，同时由于满足能量需求而增加分解代谢成本。在200-g L(-1)中，牡蛎从接触开始就抑制代谢能量的摄入，促进排泄代谢，从而消除体内的侵入性毒素。由于被抑制的摄食活动，牡蛎加速脂肪或/和碳水化合物的分解代谢，以满足能量需求。SFG的显著下降归因于能量摄入的减少(CR和Abs的减少)。EFF.)能量消耗增加(E和R增加)。(C)2007 Elsevier B.V.保留所有权利。
In order to understand the strategies of physiological adaptation, Pacific oysters were exposed to different concentrations of polycyclic aromatic hydrocarbons (PAHs). In 50 mu g l(-1), oysters, at first, maintain their metabolism similar to the rate of control. And then, if exposure is prolonged, oysters tend to decrease their energy intake while increasing catabolic cost due to satisfying the energy demand. In 200 mu g l(-1), the oyster suppresses metabolic energy intake and facilitates excretive metabolism to eliminate intrusive toxins from the body from the beginning of the exposure. Due to the suppressed feeding activities, oysters accelerate lipid or/and carbohydrate catabolism to satisfy the energy demand. A significant decrease of SFG was attributed to decreased energy intake (decreased CR and Abs. eff.) and increased energy expenditure (increased E and R). (C) 2007 Elsevier B.V. All rights reserved.
