micronucleus n.【生物學】小核。adj.-clear

micronutrient

In the second part , the influences of la on micronucleus rate were observed by using the rat marrow cell micronucleus test . and the cleavage action of la on genome dna were studied too . the results manifest that a certain concentration of la can increase micronucleus rate obviously and induce the cleavage action and structural change of genome dna (二)采用小鼠骨髓細胞微核檢測技術研究了稀土元素鑭對微核率的影響,同時采用體外培育技術和紫外分光光度法研究了鑭對基因組dna的斷裂作用,結果表明一定濃度的鑭能引起微核率顯著升高,并可導致基因組dna的斷裂以及結構的改變。

Results the mutagenicity of water body displayed a rule of well < river < pool ; the mutagenicity detected in dry season was higher than that in rainy season ; the numbers of micronucleus induced by river and pool water in dry season were found to be positively correlated with the incidence of stomach , esophagus and liver cancer , whereas only pool water showed significant relationship with stomach cancer occurrence in rainy season ; well , river and pool water in taixing city all can cause dna damage in peripheral blood lymphocytes , and water of river cause dna damage heavily 結果:水體致突變性呈塘水河水井水的規律;相同地區水體的致突變性在枯水期比豐水期強;枯水期河水和塘水誘發的微核效應與當地肝癌、胃癌和食管癌發病率有高度的正相關,而豐水期僅塘水微核效應與胃癌發病率有正相關;誘發微核率較高的井水、河水和溝塘水對人淋巴細胞都具有致突變性,其中尤以河水為甚。
