Effects of Nitrogen Sources on Nitrate Reductase Activity and Some Physiological Parameters in Psyllium （Plantago ovata F.） under Salinity Stress

The effects of three nitrogen sources （ammonium, nitrate and ammonium＋nitrate） and three salt treatments （0, 100 and 200 mM NaCl） on nitrate reductase activity, proline, soluble protein and carbohydrate contents in psylliom （Plantago ovata） plants were Studied. The nitrate reductase activity tended to increase when NO3- was included in the root-zone solution, but decrease as salinity increased. All N sources stimulated plant growth and nutrient uptake. Shoot and root dry matter tended to decrease as salinity increased, but less so when both NH4＋ and NO3- were present. Shoot biomass accumulated to significantly greater quantities under the mixed-N treatments than when produced using either NH4＋ or NO3- N-form alone. Although not statistically significant, the root biomasses showed a similar tendency. Generally, leaf proline and soluble shoot carbohydrate contents increased with increasing salinity in contrast to soluble protein which decreased regardless of the N source. Under salinity conditions, the concentration of Na＋ in shoot and root tissues was highest in ammonium-N treatment, while that of K＋ was highest in the mixed-N treatment.

车前子提取物对大肠杆菌耐药抑制作用初步研究

为了对车前子提取物耐药抑制作用进行研究,采用棋盘法测定车前子乙醇提取物与环丙沙星的联合作用,二者联合应用对大肠杆菌耐药菌株具有较好的抗菌作用。通过环丙沙星蓄积动力学试验检测车前子乙醇提取物对鸡源大肠杆菌外排泵的影响,结果表明,车前子乙醇提取物能增加环丙沙星在细胞内的蓄积量,抑制耐药大肠杆菌对抗生素的主动外排作用。三氯甲烷萃取物对大肠杆菌的药物外排具有一定的抑制作用,但其抑制作用不如乙醇提取物。

灌服酒炙车前子活性组分的胎衣不下奶牛血清代谢产物LC-MS/MS法分析

早期研究过程中发现活性组分Ⅲ和Ⅵ为治疗奶牛胎衣不下的有效物质,并已阐明其化学成分,但尚未鉴定活性组分在体内的代谢产物,因此研究旨在利用液相色谱-串联质谱（LC-MS/MS）对活性组分Ⅲ和Ⅵ的血清样品进行分析。以ACQUITY UPLC HSS T3(2.1 mm×100 mm,1.8μm)为色谱柱条件,流动相以水（含0.05%甲酸）-乙腈进行梯度洗脱,采用ESI电喷雾离子源,正、负离子模式下收集活性组分Ⅲ和Ⅵ的血清样品的质谱数据,并根据碎片离子以及相对分子质量等信息与网络数据库以及相关参考文献进行比对。活性组分Ⅲ发现包括胺类、脂类在内的共24个化合物,活性组分Ⅵ包括酚类、烷类等共26个化合物,为研制高效、经济和便捷的防治奶牛胎衣不下的中药针剂提供了新方向。
