According to coming from spanish report , the person that medicaments of the abuse inside hemophiliac , vein becomes addiction and blood are dialytic patient , rate of positive of antibody of third hepatitis virus is respectively 64 % , 70 % reach 20 % , more average crowd is apparently tall 据来自西班牙的报告，血友病患者、静脉内滥用药物成瘾者及血液透析患者，丙型肝炎病毒抗体阳性率分别为64 % 、 70 %及20 % ，较一般人群明显为高。
Then we conducted in vitro gene transfer , transfecting p388d1 with recombinant eukaryotic vector and infecting hela with recombinant adenoviruses respectively , in order to observe inhibition of constitutive or inducible cii ta gene expression by introduced complementary antisense rna of c iita and consequent do wnregulation of class ii mhc molecules expression 结果显示：含反义c ta的真核表达载体转染组成型mhc -类分子表达p388d1细胞株，经抗生素抗性筛选后表达mhc -类分子的细胞阳性率比对照组下降65
Campaired with the control groups , the absolute weight , grouth index and cell cycle of immune organs , the anae positive rates of t lymphocytes in peripheral blood , the erythrocyte c3brr and cic rosette rates were singnificantly changed in the zinc - deficient and zinc - toxic ducklings . histopathologically , lymphocytes of the immune organs were depleted , degenerated and necrotic in both zinc - deficient and zinc - toxic ducklings 缺锌和锌中毒组免疫器官的绝对重量、生长指数、细胞生长周期以及t淋巴细胞anae ~ +阳性率、红细胞c _ 3b受体花环、免疫复合物花环率与对照组比较差异显著( p 0 . 05 )或极显著( p 0 . 01 ) 。
Results ( 1 ) the positive rate of dmf . rheogram in phd with and without respiratory failure are 75 and 21 . 9 respectively . ( 2 ) the positve rate in phd with and without heart failue are 80 and 46 . 3 respectively . ( 3 ) the mean values of various parameters of ipg in positive and negative dmf rheogram have no significant difference . conclusion respiratory failure and heart falure in phd are closely correlated with dmf 结果( 1 )肺心病伴与不伴呼衰组膈肌疲劳图形阳性率分别为75与21 . 9 ； ( 2 )肺心病伴与不伴心衰组膈肌疲劳图形阳性率分别为80与46 . 3 ； ( 3 )膈肌疲劳阳性组与阴性组肺阻抗图各参数均值无显著性差异。
It showed that the induction efficiency of the resistant calli were the same among all explants of different age , but the embryos on the calli from explants of 7 days appeared earlier than those from explants 11 and 30 days . in order to compare the resistant calli induction efficiency , petioles and hypocotyls were excised from 30days aseptic seedlings to transform with pbinctbs under the same condition . the resistant calli induction efficiency of petioles was higher than those of hypocotyls . a more detailed analysis of the different types of explants showed that the number of pcr positive plants induced from petioles was higher than that from hypocotyls 在相同条件下的转化实验中，发现不同苗龄的外植体的抗性愈伤的诱导频率基本相同:还进一步研究了胡萝卜同一苗龄不同部位的抗性愈伤形成率，同时用3od苗龄(照光3周)的叶柄和下胚轴做转化实验，发现叶柄的抗性愈伤形成率高于下胚轴的抗性愈伤形成率，进一步的实验发现，由叶柄诱导的苗子的阳性率高于由下胚轴诱导的苗子的阳性率，此结果和pawlicki的结论是一致的。
