  1. In the field of the phytoremediation of copper pollution, submerged macrophytes are focused less than the terrestrial plants. in this study, ceratophyllum demersum l. and cahomba caroliniana a. gray were used as the test plant. the following two aspects were investigated in vivo methods : 1 ) the toxicity effects of cu2 + on the three main antioxidant enzymes ( including cat, pod and sod ) of two submerged macrophytes were detected at different low doses and on the chronic exposure, in order to establish the dose - effect relationship and the time - effect relationship, and thereby acquire the toxicity threshold ; and 2 ) with two submerge macrophytes throng cultured individual or combined on the chronic exposure, it was found on the bcf of copper and the influence of interspecific relationships to the submerge macrophytes resistance or bioconcentration

    本論文以兩種大型沉水植物金魚藻（ c . demersuml . ）和水盾草（ c . carolinianaa . ）為受試植物，從它們對水體中cu ~ （ 2 + ）的生物富集作用和動態，以及cu ~ （ 2 + ）對它們體內抗氧化酶的急性毒性效應和亞急性毒性效應兩方面進行了研究： 1 ）通過體內暴露不同劑量的cu ~ （ 2 + ） ，探討cu ~ （ 2 + ）對植物體內三種主要的抗氧化物酶（ sod ， pod ， cat ）的毒理效應，建立劑量?效應關系和時間?效應關系，以揭示沉水植物對cu ~ （ 2 + ）的抗性機制； 2 ）通過對金魚藻，水盾草單獨培養和共同培養的方式，分別研究了兩種沉水植物對cu ~ （ 2 + ）的生物富集系數及其動態以及兩種植物的種間關系對富集銅和植物耐性的影響，綜合評價了兩種植物在銅污染水體的植物修復中的應用前景。
  2. Dose - effect relationship between the ability of neural regeneration and radiation after re - implantation of invading sciatic nerve following one - off radiation in vitro

  3. Effects of recombinant human parathyroid hormone on the proliferation of rabbit bone marrow - derived mesenchymal stem cells and the dose - effect relationship with differentiation to osteoblast

    影響兔骨髓間充質幹細胞增殖及向成骨細胞分化的量效關系
  4. It should be note that experimental data for dose - effect relationship are still scanty, especially for low doses and low dose rates. the risk factors are deduced from a single exposure of more than 1 gy and are subject to certain uncertainties. the figures are therefore neither precise nor final

    因此危險度分析是推測性的，所根據的數據和資料主要來源於一戈以上單次照射的結果，而且有一定的不確定性，所以在應用時要留意其局限性，不能視其為精確的或不變的數據。
  5. Among the joint dose experiments, the antagonism of selenium and mercury is the most evident in the rats with 2 : 1 mol - ratio of selenium and mercury but the least in the rats with 1 : 2 mol - ratio of selenium and mercury. the results also showed that there are two essential conditions for good antagonistic effect of selenium and mercury and 1 : 1 mol - ratio relationship of selenium and mercury in the most organs ( liver, gland, spleen, stomach and lungs ). one is that the content of mercury is more than 100nmol / g, and another is the 2 : 1 dose ratio of selenium and mercury

    總體而言，雌性大鼠對硒、汞毒性的拮抗作用與雄性大鼠相比時更為敏感；相同性別的大鼠體內，聯合高劑量時硒、汞的拮抗作用最明顯，聯合中劑量時，拮抗效果相對不明顯，而聯合低劑量時，拮抗效果最差；聯合摩爾劑量比為2 ： 1 （ se ： hg ）和汞的積累濃度大於100nmol g ，是大鼠體內大部分組織器官（肝臟、胸腺、脾、胃、肺）中四川大學碩士學位論文硒、汞等摩爾比積累的兩個必要條件，同時也是硒、汞的相互作用產生最佳桔抗效果的兩個重要前提。
