  1. Using a pair of degenerate primers based on the conservative region, hmg - box, of human sry gene, tow different fragments of sox gene, essox3 and essox22 were amplified from female and male eriocheir sinensis, the sequence results indicated that essox3 and essox22 shown high homology to human sox genes, and the identities to human sox genes in dna sequence and amino acid sequence are 84 % 、 85 % and 97 % 、 81 %, respectively. it might be concluded that sox gene was highly conservative in phylogenesis

    二、研究論文1 、參照人sry基因hmg - box保守區的序列，設計一對兼并引物， pcr擴增了中華絨螯蟹的sox基因，並對擴增產物進行了克隆和測序。結果在雌雄個體中篩選出兩個不同的sox基因essox3和essox22 ，其dna序列和編碼的氨基酸序列與人相應sox基因的相似性分別為84 % 、 85 %和97 % 、 81 % ，顯示該基因在進化上具高度的保守性。
  2. In order to select male nucleo - sterile new genotype, a tentative idea was put forward for the nucleo - male sterility to attach a tps ( thermo - photoperiod sensitivity ) and a selection strategy of combination of selection and identification, at the same time, the spring and summer sowing method were used to provide different environment conditions of appraising sterility and tps. the results indicated that ( 1 ) sterility could be appraised under the spring sowing environment and tps could be appraised under summer sowing environment. ( 2 ) under spring sowing environment, sterility could be selected, but not maintained. thereby, lines selected could only be selected as recorded selection method in the experiment. ( 3 ) and then, selection was carried out from spring sowing line selected into summer sowing in same line with tps to select plants. these plants through the intercrossing selection had been combined with sterility and tps. in this way, a new selection protocol for selection sterile line with tps was formed. it mainly involves the spring and summer sowing method, recorded selection method and the intercrossing selection method

    為了選育新類型玉米雄性核不育系，提出了為玉米核不育性添加溫光敏感性的設想和選擇與鑒定相結合的策略，同時應用分期播種的方法為作物提供不同的生長和發育的環境條件，以鑒定玉米雄穗的育性變化和對不同環境條件溫光的反應.研究結果表明，春播環境下可鑒定和選擇玉米的不育性，夏播環境下可鑒定和選擇其溫光敏感性.針對玉米核不育性難以找到保持系的特性，結合兩種播期選擇兩種性狀.但春播環境下選擇的不育性群體難以通過選擇單株來保持其不育性，為記錄性群體選擇.通過從春播入選的雜合不育性優良株系群體轉移到其對應的夏播溫光敏感性入選的同一優良群體中進行優良單株選擇，能逐漸使不育性和溫光敏感性相結合而選育出純合溫光敏不育系.這種新的選擇程序主要包括應用分期播種法、記錄性選擇法和春夏兩季交叉式選擇法，使含有不育基因的可育株系逐步累積不育基因並增加了溫光敏感性而育成玉米溫光敏不育系
  3. The results from sds - page presented that there were three female specific protein subunits with molecular weights of 123 kd, 120 kd and 91 kd, respectively. we can conclude the higher molecular compose of two subunits ; the results from two dimension electrophoresis showed the isoelectric points of two female - specific spots with molecular weight of about 120kd were 5. 5 and 5. 7. immunodiffusion reactions demonstrated that vg existed both in female fat body and hemolymph, which as vn was deposited in the ovary, while not in the male

    Page電泳結果表明：麗蠅蛹集金小蜂明顯存在2條雌特異性帶-卵黃蛋白，分子量分別為181kd和136kd ； sds - page電泳分析：存在3條雌特異性帶，其分子量為123kd 、 120kd和91kd ，由此，可推定卵黃原蛋白（ vitellogenin ， vg ）和卵黃磷蛋白（ vitellin ， vn ）由2個蛋白組成，其中分子量較大的蛋白由2個亞基組成；雙向電泳結果顯示，在120kd附近有兩個特異性點，其等電點為5 . 5和5 . 7 ；雙擴散表明，麗蠅蛹集金小蜂卵黃磷蛋白的抗血清與雌隱成蟲蟲體、脂肪體、血淋巴和卵巢勻漿液均有免疫沉澱反應，而與雄蜂血淋巴無免疫反應，說明了vg與vn具有免疫同源性，是雌特異性蛋白，且由脂肪體合成。
  4. 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。
