茄子早熟育种研究Ⅱ选择指数与早熟性选择

研究结果表明,由性状果实最大周长,果实体积,门茄显蕾期,单株产量等性状构成的选择指数较好;进一步进行遗传相关分析结果认为,应用选择指数时应注意果实体积这个性状,单株产量是一个重要的辅助性状,门茄显蕾期是一个限制性因子。应用选择指数对品种评价结果认为,早熟性较好的品种有:天津早茄、西安绿茄、二民、七叶茄、白线茄和汉中荷包。     

樟树大树移栽技术试验

通过对6~12年生樟树不同处理移栽试验,结果表明:6~7年生樟树,采用一年内春秋2次截根+ABT生根粉处理,移栽成活率可达91%;10~12年生樟树,隔年截根+ABT生根粉处理,移栽成活率可达87%以上。     

In vivo kinetic study on uptake and distribution of intramuscular tritium-labeled polysulfated glycosaminoglycan in equine body fluid compartments and articular cartilage in an osteochondrial defect model

The uptake and distribution of intramuscularly (IM) administered tritium-labeled polysulfated glycosaminoglycan (³H-PSGAG) in serum, synovial fluid, and articular cartilage of eight horses was quantitated, and hyaluronic acid (HA) concentration of the middle carpal joint was evaluated in a pharmacokinetic study. A full-thickness articular cartilage defect, created on the distal articular surface of the left radial carpal bone of each horse served as an osteochondral defect model. ³H-PSGAG (500 mg) was injected IM, between 14 and 35 days after creation of the defects. Scintillation analysis of serum and synovial fluid, collected from both middle carpal joints at specific predetermined times up to 96 hours post-injection, revealed mean ³H-PSGAG concentrations peaked at 2 hours post-injection. ³H-PSGAG was detected in cartilage and subchondral bone 96 hours post-injection in samples from all eight horses. There were no statistically significant differences in ³H-PSGAG concentration of synovial fluid or cartilage between cartilage defect and control (right middle carpal) joints.

HA assay of synovial fluid revealed concentrations significantly increased at 24, 48, and 96 hours post-injection in both joints. The concentration nearly doubled 48 hours post-injection. However, no statistically significant differences were found between synovial concentrations of HA in cartilage defect and control joints.

³H-PSGAG administered IM to horses, was distributed in the blood, synovial fluid, and articular cartilage. HA concentrations in synovial fluid increased after IM administration of polysulfated glycosaminoglycan.     

母猪饲料中添加中药“泻康宁”对仔猪黄白痢的治疗试验

由埃希氏大肠杆菌引起的仔猪黄白痢会导致机体水分和电解质大量丧失 ,使机体衰弱甚至死亡 ,从而造成很大的经济损失。目前 ,大肠杆菌引起的仔猪黄白痢已成为影响仔猪发育和育成的重要疾病之一 ,成为养猪业的一大障碍。虽然应用抗生素、磺胺类药物和抗菌增效剂等治疗仔猪黄白痢有一定的疗效 ,但由于大肠杆菌具有很强的变异性 ,易产生抗药性而影响治疗效果 ,而且 ,有的药物还会在体内蓄积 ,给人类的健康带来危害 ,正因为如此 ,人们开始寻找新的无公害的药物。实验研究发现 ,中草药不仅能够促进畜禽生长发育和提高生产性能 ,调节动物机体的新陈…

加强财务预算管理,规范民营高校财务控制

民营高校财务内部控制是指投资者为使所办高校教育活动有序、高效运行,保证投资者资产的完整性,提高会计信息的真实性和准确性,获得经营效益,而制定的一系列组织、计划和调节控制制度.财务内部控制的主要环节之一是财务预算管理,这是由当今民营高校的特点所决定的.民营高校的校长都是由投资者任命的,与公立高校校长相比,他们有职、有责、有权,是民营高校行政系统的最高决策者和指挥者,民营高校的法人代表;他们具有机构设置、人事安排、经费使用、教育教学管理和校舍财产管理等相应的权力及责任,既要全面贯彻国家的教育方针和政策,又要依靠教职员工办好民营高校.
