  1. The main study in this paper included as follows : the content and distribution of heavy metals in sediments and benthic organisms from the sewage stream in guangzhou city ; the acute toxicity and joint toxicity of mercury and selenium to swordtail fish ( xiphophorus helleri ) ; the damage of mercury to the indexes of antioxidant system in the gills and livers in swordtail ( including the measurement of the activities of total antioxidative capacity [ t ~ aoc ], superoxide dismutase [ sod ], glutathione peroxidase [ gsh - px ] and the concentration of malondiald - ehyde [ mda ] ) and the relief effects of selenium on it, as well as the physiological damage of mercury on the tissues, namely : the antagonistic effect of na + - k + ~ atpase activity on the tissues between selenite and mercury, and the ultrastructural damage under the exposure of mercury

    研究內容主要有：廣州市河涌沉積物及底棲生物體內重金屬含量及評價；汞和硒對劍尾魚的急性毒性和聯合毒性及安全濃度的評價；汞對劍尾魚鰓和肝臟中抗氧化系統的毒性，包括對總抗氧化能力、超氧化物歧化酶、谷胱甘肽過氧化物酶活力及丙二醛含量的測定及硒對其保護作用；汞對劍尾魚組織生理毒性即：汞對na ~ + - k ~ + atpase活力的影響及硒的保護作用和汞和對劍尾魚組織超微結構的損傷等。以高氯酸?硝酸消化法和火焰原子吸收分光光度法測定了廣州市河涌沉積物和底棲生物中重金屬含量。
  2. Dna damages caused by so2 and lead acetate were studied with the single cell microgel electrophoresis technique ( or comet assay ) in order to confirm the damaging degree of lead ( as an important component of atmosphere particle matter ) on dna from male mice exposed to so2. the migrating distances of dna of brain, lung, spleen and kidney cells of mice increased significantly, compared to the control group under conditions of single and combined poisoning of so2 ( 42mg / m3 ) and lead acetate ( 0. 2 % ), and lead could strengthen dna damage degree by so2 in nuclear dna of brain, kidney, spleen cells. damaging degree of so2 on nuclear dna of lung cell of mice was more severe than that of lead

    為了明確大氣顆粒物中的重要組分? ?鉛在二氧化硫所致dna損傷中的作用程度，利用單細胞凝膠電泳技術（ singlecellgelelectrophoresis ， scge ，或稱彗星實驗， cometassay ）研究了鉛與二氧化硫的聯合污染，結果表明在42mg m ~ 3so _ 2和0 . 2醋酸摘要一abstract鉛單獨及聯合染毒條件下，小鼠腦、肺、腎、脾細胞dna遷移距離均比對照顯著增加;鉛加劇了50 :對腦、腎、脾細胞核dna的損傷程度; 50 :對肺細胞核dna的損傷程度要比鉛的損傷大，小鼠肺細胞核dna遷移距離在50 :和醋酸鉛聯合作用組與醋酸鉛單獨作用組間有極顯著性差異（ p < 0 . 01 ） ，而與502單獨作用組間沒有顯著性差異。
  3. Before now most of the research has concentrated on the action of single compounds against organisms. when two or more chemicals are applied simultaneously to a living system or unit, the combined effect may be one of the followings : additive action, antagonism and synergism

    目前，有關污染物的生物效應研究多數還是集中在單個化合物的生物效應，隨著多種污染物（包括重金屬）進入水域環境后，所發生的聯合毒性效應往往表現為相加、拮抗或增毒作用。
  4. In contrast, most mature somatic cells in human tissues express undetectable or low telomerase activity, implying the existence of a stringent and negative regulatory mechanism. in this study, we report the effects of cisplatin on telomerase activity in human ovarian cancer cells. the special relationship between activity and cancer has a important application value

    順鉑（ ddp ）是卵巢癌化療中最有效的基礎藥物之一，它是一種類烷化劑的抗腫瘤藥物，為細胞周期非特異性藥物，可作用細胞周期的任一時相，利於臨床的聯合用藥，但由於ddp的諸多毒副作用及卵巢癌細胞易產生對其耐藥性，常使化療效果不滿意。
  5. The results showed that the interaction between selenium and mercury in rats mostly is the antagonism on the both acute toxicity tests and sub - chronic ones. liver, kidney, gland, heart, spleen, lungs, stomach and testis of rats are the target organs of mercury, selenium and their joint poison. and liver, kidney and spleen are three most important target organs

    研究結果表明，大鼠體內硒與汞的急性和亞慢性相互作用主要表現為拮抗作用；大鼠肝臟、腎臟、胸腺、心臟、脾、肺、胃和睪丸等組織器官都是硒、汞及其聯合毒物的靶器官，其中肝臟、腎臟、脾臟是三個主要靶器官；肝臟中汞與硒的含量呈高度正相關，腎臟中汞與硒的含量呈負相關，但相關性不甚好。
  6. Due to the presence of multiple pollutants including metals in natural environments, studies on joint - action toxicity are becoming increasingly popular. these studies are indispensable to measuring and predicting impacts of chemical pollutants on organism. however, studies of the joint toxicity of pesticides and metals in the aquatic ecosystem were few

    因此，有關預測和治理化學污染物對生物產生毒性的聯合作用研究，已越來越受到大家的關注，特別是對農田水系農藥和重金屬等主要污染物共存時的生物效應與機理方面的研究。
