Study on Liver-protective Effect of Chinese Herbal Compound Probiotics on Acute Liver Injury Layers

This experiment was conducted to investigate the liver-protective effect of Chinese herbal compound probiotics (CHCP) on acute liver injury layers.One hundred and eight 1 day old hens were divided into 4 groups with 3 replicates in each group and 9 layers per replicate in trial 1.The layers in model groups Ⅰ to Ⅲ were gavaged with 10% (V/V) soybean oil solution of carbon tetrachloride (SCCl₄) according to 1,2 and 4 mL/(kg·BW) at 14,28 and 35 d,respectively.The layers in control group were gavaged with 2 mL/(kg·BW) soybean oil.In trial 2,sixty 1 d layers were divided into 5 groups:Control group (soybean oil),model control group(SCCl₄)and low-dose,middle-dose and high-dose CHCP group (SCCl₄+1‰ CHCP,SCCl₄+2‰ CHCP and SCCl₄+4‰ CHCP respectively).CHCP were used by drinking water since 7 days.SCCl₄ were gavaged according to 2 mL/(kg·BW) at 14 and 28 d.The results showed as follows:The model of layers liver damage could be built by intragastric administration of 2 mL/(kg·BW) 10%(V/V) SCCl₄ at 14,28 d respectively,with the signs of hepatic steatosis,severe vacuolar degeneration,nuclear condensation and necrosis.Compared to the model control group,the serum AST levels in low,medium and high dose CHCP groups were decreased by 4.35% (P > 0.05),7.57% (P > 0.05) and 9.79% (P < 0.05),the serum ALT levels in medium and high dose CHCP groups were decreased by 34.92% (P < 0.01),36.51% (P < 0.01),the serum total bilirubin content in medium and high dose CHCP groups were decreased by 25.49% (P < 0.01),27.45% (P < 0.01).The liver cell congestion was reduced to varying degrees in different dose CHCP groups,and the liver cell had no vacuoles,arranged in neat rows,abundant cytoplasm and uniform in different dose CHCP groups.In conclusion,2‰,4‰ CHCP could reduce hepatocyte necrosis,decrease the serum activities of ALT,AST and total bilirubin levels,and had protective effect on hepatic injury induced by SCCl₄.     

中医治疗牛口疮

口疮又称烂口、口炎,以口腔粘膜出现溃烂、红肿及口内流涎为特征。多发生于夏秋季节。现代兽医学中的口膜炎属此范畴。1病因病理气候炎热,劳役过重,饲喂热料,热邪郁遏于脾。脾开口于舌,脾热则生痰,痰热互结循经上炎于口;又脾胃为表里,胃热蒸于口而发疮;诸经实热皆应于心,心火上炎则口舌生疮。此外,脾又为后天之本,脾气虚,气血化生无源,口失濡养,或肾虚不能制阳,则虚火上炎亦可成疮。机械性损伤,如草料的芒剌、尖锐硬物以及疫毒感染等,也是引起本病的重要原因。     

英国将采取科学的猪福利评估标准

<正>跛足、尾部损伤、身体损伤、护理栏和环境丰容,在BPEX和布里斯托大学联合进行的一项试点试验把这些指标确定为评估肥育猪动物福利的适宜指标。对于母猪则评估体况评分、肩部和外阴损伤等指标。     

拖拉机连杆常见损伤的检测

连杆是拖拉机曲柄连杆机构的重要组件。连杆损伤后直接影响发动机工作性能,使发动机压缩压力减小,功率下降。本文对连杆的主要损伤:弯曲、扭曲变形、大小端孔磨损、大端孔结合面和连杆螺栓孔面的损伤的检测方法进行了叙述,以提高发动机的修复质量。     

综放工作面过断层片帮控制技术应用

为保证工作面过断层期间的安全回采，对3号煤层片帮、冒顶原因进行分析。经数值模拟计算，3103综放工作面为有效控制煤壁片冒，应控制端面距小于500 mm,调整支架工作阻力为13 000～14 000 kN。通过对打设片帮处锚杆进行补强加固以及对产生裂隙的构造影响区施工采取钻孔注浆等措施，使3103综放工作面片帮大小和范围均大幅下降，最大片帮宽度从6.3 m变为2.1 m,最大片帮深度和距离均低于1.4 m,应用效果良好。     

2个烟草品种体内毒性差异的比较

以2个不同基因型烟草品种(NDY-1和NDY-2)卷制的单料烟,分别持续烟熏SD大鼠56 d,检测其脾组织中活性氧自由基(ROS)、丙二醛(MDA)、蛋白质羰基(PC)的含量和DNA-蛋白质交联(DPC)系数以及病理变化。结果表明,与健康对照组(新鲜空气暴露)相比,随着暴露时间的延长,试验大鼠脾组织的ROS,MDA,PC和DPC水平均显著升高,脾组织呈现明显的病理变化;与NDY-1组相比,NDY-2组脾组织的氧化损伤、病理损伤较轻。说明NDY-2烟样较NDY-1烟样的体内毒性效应较小。
