保肝弥毒胶囊治疗抗精神病药物所致肝损害

利用保肝弥毒胶囊治疗抗精神病药物所致肝脏损害40例,并与肝泰乐和肌苷片联合治疗组作对照观察,疗程为4周.结果显示在治疗两周时两组疗效相当,在4周时,保肝弥毒胶囊治疗组疗效显著高于对照组.     

淫羊藿对小鼠肝组织部分生化指标的影响

目的:探究饮用不同浓度淫羊藿提取物溶液对小鼠肝脏指数及肝脏中肝糖原、甘油三酯、胆固醇含量等生化指标的影响。方法:选用雄性昆明小鼠40只,随机均分成4组,分别为对照组(饮用自来水)和饮用淫羊藿提取物溶液低(2g/L)、中(4g/L)、高(8g/L)剂量组,试验期为3周。试验结束后停食24h,正常饮水,称重,颈椎脱臼处死,取肝脏,测定肝脏指数及肝脏中肝糖原、甘油三酯、胆固醇含量,研究其对部分生化指标的影响。结果:与对照组比较,低浓度组肝脏指数升高(P0.05);中、高浓度组肝糖原、甘油三酯和胆固醇含量均升高(P0.01),低浓度组肝糖原含量升高(P0.05),甘油三酯含量升高(P0.01)。结论:饮用淫羊藿浓缩物可提高肝组织中肝糖原、甘油三酯、胆固醇含量,且呈现量效关系,在一定给药浓度范围内,肝脏指数呈现相应的数量关系。     

Construction of a hepatic stellate cells subtracted cDNA library of differentially expressed genes in normal mice and mice with Schistosomiasis japonica

To construct a hepatic stellate cells (HSCs) subtracted cDNA library to find differentially expressed genes in normal mice and mice infected with Schistosomajaponicum (S. japonicum). Suppression subtractive hybridization (SSH) was used. The cDNA fragments of normal mouse were compared to those of schistosoma-infected mice to find differentially expressed genes. Then differentially expressed cDNA fragments were directly inserted into T/A cloning vector to set up the subtractive library. Amplification of the library was carried out with transformation of DH5α. The amplified library contained more than 400 positive bacterial clones, which were then hybridized with forward and backward subtracted probes for differential screening, One hundred positive bacterial clones were randomly selected for sequencing and BLAST analysis, Finally, virtual Northern Blot confirmed such differential expression. The subtracted cDNA library of differentially expressed genes of HSCs was constructed successfully, the library is efficient and lays foundation for screening and cloning new and specific genes of schistosomiasis.     

“比较过氧化氢在不同条件下的分解”实验的创新改进

利用改进的实验装置比较过氧化氢在FeCl3溶液和肝脏研磨液条件下的分解反应,既直观、定量地说明酶催化作用具有高效性,又可以说明酶只改变反应速率不改变反应平衡点的特性。     

更正

任何药物——烟 服用任何药物后的30分钟内都不能吸烟。因为烟碱会加快肝脏降解药物的速度，导致血液中药物浓度不足，难以充分发挥药效。试验证实，服药后30分钟内吸烟，血药浓度约降至不吸烟时的1／20。     

以"肝脏"为核心的专题复习

肝脏是人体最大的腺体,正常成年人约1.5 kg.它与体内多方面的生理活动密切相关,对于生命的维持有重要意义.肝脏除了分泌胆汁外,在代谢方面,对人体内蛋白质、糖类、脂类等很多物质的代谢都有影响;肝脏还有解毒作用;此外,肝炎等肝脏疾患会严重影响人体健康.     

Liver fibrosis identification based on ultrasound images captured under varied imaging protocols

INTRODUCTION There are more than 20 million chronic hepatitis patients in China and 300,000 people die of liver related disease every year, which is widely recog- nized as an emerging public health crisis. Moreover, liver damage can cause higher than normal amounts of collagen fiber deposits in the extra-cellular spaces of the liver cells and cause the liver cells to lose blood and lead to liver fibrosis, which is a necessary stage to cirrhosis and a reversible consequence, so it is critic…

一个词语 两个画面——《普罗米修斯》教学片段及分析

正在解读四年级下册的神话故事《普罗米修斯》时,我试着寻找牵一发而动全身的词。读着读着,我的目光聚焦在一个词语上——惩罚。揪住这个词,我又读出了两个画面——一"锁"一"啄"。因为这两个画
