The mutagenicity of seed powder and seed oil of transgenic CryIA cotton to mammals and fish was evaluated in this study. The raw cotton seed powder or seed oil was mixed into mice and fish's diet. Cyclophosphamide and NaF were used as positive controls respectively. Regular cotton seed powder and seed oil were used as negative controls. The micronucleus frequency in mice bone marrow polychromatic erythrocytes and in eripheral erythrocytes of Zebrafish were assayed in this study. The sperm malformation rate in mice was also investigated.

摘 要：分别以环磷酰胺和氟化钠作为阳性诱变剂，以普通棉的棉籽粉及棉籽油作为对照物，同时设阴性对照组，以成年封闭群昆明种雄性小鼠和斑马鱼为实验材料，将棉籽粉或棉籽油掺入饲料中饲喂小鼠或斑马鱼，检测小鼠骨髓嗜多染红细胞（Polychromatic erythrocytes， PCE）微核率（Micronucleus frequency， MN‰）和精子畸变率，以及斑马鱼外周血红细胞微核率。

objective inquire into the value of eet and cag in the diagnose of coronary heart disease.methods review and analyze132cases of positive eet and77cases of results of cag.results positive cag:58cases（75%）;negative cag:19cases（25%）;single-branch pathology18cases;double-branch pathologies:40cases;many-branch pathologies:19cases;stc extension:25cases;s-wave deepeness:21cases;u-wave inverˉsion:2cases.conclusion among the patients of eet,dangerous factors conform to the results of cag inclinical symptom relatively,among females,young people and non-clinical symptom,false positiveness is more.

目的 探讨活动平板运动试验与冠状动脉造影在冠心病诊断中的价值。方法对132例活动平板运动试验阳性，77例冠状动脉造影结果进行回顾性分析。结果冠状动脉造影阳性58例（75%），阴性19例（25%），单支病变18例，双支病变40例，多支病变19例，stc延长25例，s波加深21例，u波倒置2例。结论在活动平板运动试验患者中，有危险因素和临床症状与冠状动脉造影结果较相符，女性、年轻人和无临床症状者假阳性较多。

The result was consistent with that of double-disk synergy tests. 61 strains were found to be ESBLs negative detected using VITEK GNS-506. Among them, 19 strains were found to be ESBLs positive.

检测102株大肠埃希菌中，仪器检出41株阳性，纸片协同法对照也为阳性，但仪器检测的61株阴性菌中，纸片协同法对照有19株为阳性。

The fusion DNA fragments of ag85b-mpb64 and ag85b-mpb64-esat-6 were obtained by PCR andSOE technique. Various DNA vaccines were constructed with the pcDNA3.1: fusion of two genes, and of three genes, bivalent combinations and trivalent combinations(pCA+pCM+pCE6). BALB/c mice were vaccinated with this DNA vaccines.The mice injected withBCG were positive control and the mice injected with pCDNA3.1 and PBS were negative control.The mice were immunized 3 times with 2-wk intervals. The animals in group BCG were only inoculatedsubcutaneously with 1×10~6 CFU BCG at initial vaccination. The serum IgG titers and IgG isotype weredetermined using iELISA coated with M. bovis PPD and rMAE protein expressed and depurated inprokaryotic expression system every week.
