核酸減少
英文
denucleination-
We found nuclear deformation lymphocytes with increased heterochromatin and impaired thymus epithelium cells with increased lysosomes and deformation of mitochondrias. ( 4 ) effects on mouse liver of so2 challenge : so2 can cause significant liver injury. he staining showed several kinds of necrosis of liver including spot necrosis, focal necrosis and submassive necrosis infiltrated with lymphocytes, monocytes, few neutrophils and eosinophils ; tem observation showed fatty degeneration with dispersion of fatty droplets and dilation of rough endoplasmic reticulums, acid degeneration with significant hyperplasia of mitochondrias, necrosis of hepatocytes with karyorrhexis and other organelles losing their normal structure
（ 4 ）二氧化硫染毒對小鼠肝臟的組織學結構有明顯影響，可引起肝臟點狀壞死、灶狀壞死甚至片狀壞死，伴隨不同程度的炎性細胞浸潤；透射電鏡觀察發現二氧化硫可引起肝細胞脂肪變性、嗜酸性顆粒變和壞死，脂肪變肝細胞中可見大小不等的脂滴存在，嗜酸性顆粒變肝細胞中可見線粒體明顯增生，壞死肝細胞可見細胞核結構破壞，細胞器減少，細胞膜不完整。Dig labeled probe hybridization with solid pcr product was performed as well as electrophoresis of liquid product, this method combines rna purification, pcr amplification and nucleotide probe hybridization detection together and has many advantages including better rna purity, less time consumption, reliable positive reaction and 10 times sensitivity as rt - pcr gel running detection, reduce false positive result, unpurified nucleotide requirement, loug infected plant organism can be detected by solid hybridization
2 ）結果可靠，雜交特異性誘捕目的片段，同時去除了核酸中存在的pcr抑制物質，減少了因核酸提取不純造成的漏檢現象，結果輸出通過雙重判定保證了結果的可靠性。 3 ）靈敏度高，通過雜交進行結果判定，靈敏度比傳統的rt干cr大約高10倍。Abstract : the defects such as inclusion, splitting, dislocation and dendrite in the pbxla1 - x ( zry tiz sn1 - y - z ) o3 ( plzst ) single crystal grown from pbo - pbf2 flux by the slow cooling self - seeding technique were discussed in this paper. the forming mechanism of these defects were analyzed and some measures to eliminate the defects were proposed
文摘:本文介紹了助熔劑緩慢降溫自發成核法生長的稀土摻雜鋯鈦錫酸鉛鑭（ plzst ）晶體中出現的幾種缺陷：包裹體、開裂、位錯、枝晶，分析了這些缺陷的形成機理並提出了減少和消除這些缺陷的一些措施。When inadequate n was added, the chloroplast structure in mesophyll cell was damaged in ear leaf, the amount of carbohydrate decreased in mestome sheath, and excessive n - redistribution and n - transportation to grain from vegetative mass appeared, which resulted in earlier leaf senescence. excessive n application led to too high activity of nitrate reductase, excessive vigorous nitrogen metabolism and too much exhaustion of carbohydrate in ear leaf, which resulted in the lack of enough carbohydrate in the lower leaf, meanwhile, the expansive chloroplast grana lamellae in leaf mesophyll cell and starch grain without nuclear in mestome sheath cell was observed, which led to the decrease of chlorophyll content and photosythetic capacity in maize leaf, then the early senescence occured
氮肥用量不足導致穗葉葉肉細胞葉綠體結構性差，維管束鞘細胞碳水化合物累積減少，營養體氮素再分配率大而引起葉片早衰；而過量供氮則導致生長後期硝酸還原酶活性過高，氮素代謝過旺，消耗了大量碳水化合物，以致下位葉不能得到充足的碳水化合物供應而提早脫落，同時葉肉細胞葉綠體片層結構膨脹，呈「肉汁化」特徵，維管束鞘細胞澱粉粒大量消耗，無核澱粉粒出現，從而葉片葉綠素含量下降，光合能力降低而出現早衰。That is to add a special fluorescence - based dna internal standard in the telomerase elongated ts primers, then do pcr amplification after a step of refinement ( hydroxybenzene / chloroform extracting, and deposited by ethanol ). sequencing analysis of pcr product was done on 310 gene scan analysis ?. 1. 2 dna sequencer to determine telomerase activity. notably, this method eliminated the restraining factors of taq dna polymerase, making it possible to erase the sample differences met in pcr and eradicate the annoying phenomena of pseudo negative results
在kim等開發的端粒重復擴增分析法（ trap ）的基礎上進行改進，即通過對端粒酶延伸ts寡核昔酸反應產物的精製，消除了pcr擴增中抑制taq酶活性的因素，從而減少了樣品之間pcr擴增上的差異和假陰性現象的發生，提高了判斷樣品端粒酶陰、陽性的準確率和定量的準確性。分享友人
