2015/3/5
Polychlorinated biphenyls (PCBs) stimulate oxytocin secretion from bovine granulosa and luteal cells. Since oxytocin on the one hand is released from ovarian cells by cortisol and on the other hand PC...
The importance of increased levels of oxytocin induced by naloxone to milk removal in dairy cows
dairy cows milking oxytocin naloxone
2015/3/5
The aim of this study was to test whether a more pronounced oxytocin release induced by naloxone during milking causes higher efficiency of milk removal. Eight pregnant multiparousHolsteincows from se...

2015/3/5
The subchronic safety of sanguiritrin, a mixture of sanguinarine (SA) and chelerythrine (CHE) quaternary benzo[c]phenanthridine alkaloids (QBA), obtained from Macleaya cordata was assessed. Rats were ...
为分析携带blaCTX-M-65、rmtB和fosA3多重耐药质粒pHN7A8的适应性代价，将犬源大肠杆菌7A8的多重耐药质粒pHN7A8转化入大肠杆菌JM109中，获得转化子7A8JT，并采用生长曲线测定和竞争试验方法研究pHN7A8对宿主菌适应性的影响。结果表明，携带pHN7A8的转化子7A8JT和受体菌JM109的生长曲线相似，但前者对于后者有竞争优势，未发现质粒pHN7A8对宿主菌产生适应...
The fluoroquinolones are a series of synthetic antibacterial agents that are used in the treatment of a variety of bacterial infections. These agents inhibit the DNA gyrase, abolishing its activity by...

Effects of sodium humate (HuNa), containing 61.9% of humic acids in dry matter, on utilisation and retention of dietary iodine were investigated in balance experiments carried out in pigs. A control g...
为研究腹水综合征（AS）肉鸡肺组织NO、ET-1及相关指标变化和复方中药对其的防治作用，将316羽14日龄罗斯肉鸡随机分为空白组（N组，常温，常规饲养）、模型组（C组，9~11 ℃，添加3%猪油和4%鱼粉的高能饲料，0.12% Na+饮水饲养）和复方中药高（T1）、中（T2）、低（T3）剂量组（饲养同C组，每天于饮水中分别给予2、1、0.5 mL•kg-1复方中药）以及L-Arg组（L...
研究鸡源大肠杆菌耐药性及中药对大肠杆菌耐药性消除作用。选择22种抗生素采用Kirby-Bauer法对山西省部分地区分离的20株致病性鸡源大肠杆菌进行耐药性检测，对分离菌株进行质粒分析和耐药质粒转化试验，并分析多种中药对大肠杆菌耐药性的消除作用。结果显示，20株试验菌对测试抗生素均存在不同程度的耐药性，其中5耐及5耐以上的菌株占分离菌株的90%，试验菌对青霉素耐药率最高（90%），其次为恩诺沙星（8...
