目的探讨血浆脑钠肽（BNP）水平与急性心肌梗死（AMI）面积的关系.方法以86例AMI患者为观察对象,根据梗死相关部位的不同将其分为前壁心肌梗死组57例,下壁心肌梗死组29例.结果 Aldrich公式法预测的心梗面积与治疗前BNP水平显著相关,而QRS积分法预测的心梗面积与治疗后BNP水平显著相关（r分别为0.889,0.872,P〈0.01）;前壁心肌梗死组治疗前BNP水平高于下壁心肌梗死组.结论 BNP与AMI的面积有相关性,BNP越高,心肌梗死的面积越大,BNP可能为急性心肌梗死初期的危险分层提供重要依据. 相似文献

3种消毒剂对水生动物3种主要致病菌的载体定量杀菌试验 总被引：1，自引：0，他引：1
通过载体定量试验对四羟甲基硫酸磷(THPS)、溴硝醇(BNP)和甲醛溶液的杀菌效果进行测定。结果表明,THPS对于嗜水气单胞菌BSK-10菌株的平均杀灭率在浓度为0.500μl/L时,在THPS与消毒剂接触5 min内即100%被杀灭。而甲醛溶液浓度为0.500μl/L时同样接触5 min杀灭率未达100%;THPS对于爱德华氏菌Et菌株的平均杀灭率与菌株BSK-10相近;而对于哈维氏弧菌GYC1108-1株的平均杀灭率在浓度为1.00μl/L时,在菌与消毒剂接触5 min内即100%被杀灭。而甲醛溶液浓度为0.500μl/L时同样接触5 min杀灭率未达100%。BNP对于菌株BSK-10的平均杀灭率在浓度为16 mg/L时,在菌与消毒剂接触5 min内即100%被杀灭;而对于菌株GYC1108-1的平均杀灭率在浓度为8 mg/L时,在菌与消毒剂接触5 min内即100%被杀灭;BNP对于菌株Et的平均杀灭率与菌株GYC1108-1相近。试验表明THPS相对BNP和甲醛溶液的杀菌效果好,鉴于甲醛溶液本身对水体和水生动物的有害影响,可采用四羟甲基硫酸磷取代甲醛溶液。 相似文献

Objective – To evaluate the effects of noncardiac disease on c‐terminal brain natriuretic peptide (cBNP) concentrations in dogs. Design – Prospective observational study. Setting – Urban university veterinary hospital. Animals – Thirty‐eight apparently healthy dogs, 28 dogs with cardiac disease (14 CHF, 14 non‐CHF), and 81 dogs with primary noncardiac diseases. Interventions – none. Materials and Methods – Plasma was collected from each dog and analyzed for active (cBNP) B‐type natriuretic peptide using an assay that is being investigated for commercial use (Biosite). Measurements and Main Results – Dogs with CHF had significantly higher plasma cBNP concentrations than dogs with subclinical cardiac disease, apparently healthy dogs, or dogs with primary noncardiac disease. However, 21% (28/133) of dogs without CHF (including healthy dogs, dogs with primary noncardiac disease, and dogs with subclinical cardiac disease) had cBNP concentrations above previously identified diagnostic thresholds for CHF, reiterating the importance of reestablishing new diagnostic cutoffs when considering comorbidities affecting B‐type natriuretic peptide levels. Conclusions – A clinically relevant proportion of nondyspneic dogs with primary noncardiac diseases have increased cBNP concentrations that exceed previously identified diagnostic thresholds, potentially limiting the ability of this test to identify CHF when noncardiac comorbidities exist. Interpretation of increased cBNP concentrations in such cases must be appropriately interpreted with further diagnostic investigation. 相似文献

目的：探讨急性心肌梗死（ AMI）患者血清中IgA,IgG,IgM,BNP和D-二聚体（ D-D）浓度的变化与AMI的关系。方法利用免疫比浊法和荧光免疫法对60例AMI患者血清中IgA,IgG,IgM,BNP和D-D浓度进行测定,并与30例正常对照组比较。结果 AMI患者血清中的IgA,IgG,IgM,BNP 和D-D浓度明显高于正常对照组,与疾病严重程度呈正相关。结论监测AMI患者血清IgA,IgG,IgM,BNP 和D-D浓度的变化,对AMI严重程度评估和疗效观察有重要的临床意义。 相似文献
