肥料和硫处理对镉胁迫下茭白植物络合素（PCs）含量的影响

以单季茭品种蒋墅茭和双季茭品种葑红早为试材,土壤为栽培介质,对100 mg?L-1 Cd2+胁迫进行不同肥料和不同浓度的硫处理,研究了茭白根系和叶片中的非蛋白巯基、谷胱甘肽及植物络合素含量变化。结果表明：供硫能促进茭白根系和叶片中非蛋白巯基、谷胱甘肽及植物络合素含量的增加,能增强茭白对镉胁迫的抗性;无机肥（三元复合肥）处理的谷胱甘肽、植物络合素含量高于有机肥（菜籽饼）处理;根系中的非蛋白巯基、谷胱甘肽及植物络合素含量显著高于叶片;品种间则以蒋墅茭高于葑红早。     

镉胁迫下硫元素与肥料交互作用对镉在茭白各器官中积累的影响

以茭白（Zizania latifolia Turcz.）的单季茭品种蒋墅茭和双季茭品种葑红早为材料,以土壤为栽培介质,研究了100 mg/L Cd2＋胁迫下,不同浓度硫处理和不同种类肥料交互作用对茭白各器官中Cd2＋积累的影响。研究结果表明,Cd2＋在茭白不同器官的积累表现为根〉短缩茎〉叶〉肉质茎;不同肥料间,有机肥处理下茭白各器官中Cd2＋的积累量同比均显著低于无机肥处理;品种间存在明显差异,葑红早各器官中Cd2＋的积累量高于蒋墅茭;硫元素能促进茭白根系中的Cd2＋向地上部转移。     

The Use of Cefquinome in Equine Semen Extender

Antibiotics are commonly used in equine semen extender for conservation, if semen has to be stored cooled for a maximum of 48 hours or frozen, to eliminate pathogenic or potentially pathogenic bacteria from semen and reduce the risk of postmating endometritis. Little is known about the effect of antibiotics on spermatozoa when semen is stored over a longer period. Cefquinome, a broad spectrum antibiotic and fourth-generation cephalosporin, has been proven to be a powerful drug for the treatment of endometritis and mastitis in different species. Recently in equine studies, it was found to localize in high concentrations in the endometrium. Therefore, cefquinome was used as the antibiotic in semen extender and compared with a commercial semen extender containing gentamicin for effects on motility and membrane integrity of spermatozoa. During the breeding season, ejaculates from nine light horse stallions were collected and half of each ejaculate was stored for 48 hours in modified Kenney type semen extender containing either cefquinome or gentamicin. At 0, 24, and 48 hours, aliquots (20 μL) of the stored semen were evaluated for (progressive) motility and membrane integrity, as well as for various motility parameters by computer assisted sperm analysis. No differences (P > .05) were found in total motility or progressive motility between extenders at any time point. However, there were differences (P < .05) in velocity parameters, although the effect of velocity parameters on fertility is not clear. In general, semen parameters after storage in non-fat dried skim milk semen extender containing cefquinome are comparable with those after storage in semen extender containing gentamicin. The wider spectrum of bactericidal activity possessed by cefquinome may prove to be beneficial in some cases.

金芩芍注射液含量测定的不确定度分析

为了探讨金芩芍注射液含量测定的不确定度分析评定,通过分析测量过程,建立数学模型,确定不确定度来源,评价各标准不确定度分量合成标准不确定度,评定扩展不确定度,给出不确定度评定结果报告。金芩芍注射液含量测定结果可表示为(2.96±0.04)mg/m L(k=2)。测量结果不确定度的主要来源为天平称量、高效液相色谱仪和小体积玻璃量具。     

双黄连注射液对中性粒细胞磷酸二酯酶4B基因表达的影响

本试验以主要在中性粒细胞中表达的磷酸二酯酶4B基因为靶基因,研究双黄连注射液的抗炎机制.采用半定量RT-PCR法检测双黄连注射液在不同时间对磷酸二酯酶4B基因表达的影响.结果发现双黄连注射液与中性粒细胞共孵育1 h时对磷酸二酯酶4B基因表达无明显的影响,当孵育到3 h时即可极显著抑制磷酸二酯酶4B基因的表达(P＜0.01).本试验结果表明,双黄连注射液能在基因转录水平上抑制中性粒细胞内磷酸二酯酶4B基因的表达,提示其能使cAMP含量升高而抑制中性粒细胞等炎症细胞的活化,从而发挥抗炎作用.
