- 12例原发性高血压患者(男性5例,女性7例;年龄40±4a)自身交叉服用长效硝苯地平(下称Nif)20mg, qm×2wk; 长效美托洛尔(下称Met)0.1g, qm×2wk。Twelve patients (M5, F7; age 40 ?4a) with primary hypertension underwent a crossover study with oral administration of sustained-release formulations of nifedipine tablet 20 mg, each morning at 8AM X 2 wk and metoprolol tablet 0.1g, each morning at 8 AM X 2 wk.
- Nif,Dil,Cap,Ena在10-4,10-5,10-6,10-7mol/L浓度下,对15%胎牛血清(FBS)所致的PASMC增殖均有明显抑制,且呈剂量依赖性的关系(P<0.05,与对照组相比);Under the concentrations 10 -4 ,10 -5 ,10 -6 ,10 -7 mol/L,Nif,Dil,Cap,Ena obviously inhibit PASMC proliferation induced by 1 5%25FBS and are dependent on dosage. ( P < 0.05 ,compared with control groups).
- 实验结果表明,在0.1mol/LNH3-NH4Cl(pH9.6)溶液中,Nafion-MWCNTs/GC,对NIF具有明显的催化和增敏作用,还原峰电位由-0.85V(裸电极)正移到-0.75V(vs.AgCl/Ag)(修饰电极),灵敏度增加约7倍。In 0.1 mol/L NH3-NH4Cl (pH 9.6) buffer, GC/Nafion+MWCNTs exhibited a remarkable catalytic and enhanced effects on the current response of NIF. The reductive peak potential of NIF was shift from 0.85 V (bare GC) to 0.75 V (vs. AgCl/Ag) (GC/Nafion+MWCNTs), and the sensitivity increased ca. 7 times.
- 肺炎克氏杆菌（Klebsiella pneumonia, Kp）NifA蛋白中心结构域C3区的点突变型（Thr-290?Val）丧失了激活nif基因转录的功能，说明这个Thr残基对NifA中心结构域的转录激活功能是关键的。Replacement of the conserved amino acid residue Thr-290 by Val in the C3 central domain region of Klebsiella pneumoniae (Kp) NifA resulted in a loss of transcriptional activation of nif genes. Thus, the conserved Thr-290 residue appears to be critical for functional activation of the NifA central domain.
