Surgical outcome and ocular complications of evisceration and intraocular prosthesis implantation in dogs with end stage glaucoma: a review of 20 cases

Surgical outcome and complications following evisceration and implantation of intraocular silicone prosthesis (ISP) in 20 canine eyes with end-stage glaucoma were analyzed, including clinical signs, complications, cosmetic appearance, and owners' responses. The mean postoperative follow-up time was 312 days. Major short-term surgical complications were central corneal ulceration (6/20) and infections (3/20), while long-term complication was keratoconjunctivitis sicca (KCS) (2/20). All patient owners (100%) showed satisfied with the surgical outcome and postoperative cosmetic effect including 85% of the owners gave an excellent or good rating of satisfaction. No more medication needed for long term control except the KCS cases. With careful case selection and post-operative care, evisceration with ISP implantation proves a good and safe surgical procedure with minimal complications for end stage glaucoma.     

苏氨酸和异亮氨酸对皖西白鹅屠宰性能、器官指数及肠道形态结构、消化酶活性、抗氧化和免疫指标的影响

本试验旨在研究苏氨酸和异亮氨酸对皖西白鹅屠宰性能、器官指数及肠道形态结构、消化酶活性、抗氧化和免疫指标的影响。选取30日龄体重相近的皖西白鹅180只,随机分为3组,每组3个重复,每个重复20只。对照组饲喂基础饲粮,苏氨酸组在基础饲粮中添加2.0 g/kg的L-苏氨酸,异亮氨酸组在基础饲粮中添加2.5 g/kg的L-异亮氨酸。试验期60 d。结果表明：1）各组之间90日龄屠宰性能和器官指数无显著差异（P>0.05）。2）异亮氨酸组60日龄十二指肠和空肠绒毛高度、隐窝深度显著或极显著高于对照组（P<0.05或P<0.01）,苏氨酸组60日龄十二指肠、空肠和回肠隐窝深度及90日龄十二指肠和回肠绒毛高度显著或极显著高于对照组（P<0.05或P<0.01）。3）苏氨酸组和异亮氨酸组60、90日龄十二指肠胰蛋白酶活性极显著高于对照组（P<0.01）,苏氨酸组60、90日龄十二指肠麦芽糖酶活性及90日龄空肠淀粉酶、乳糖酶活性显著或极显著高于对照组（P<0.05或P<0.01）。4）异亮氨酸组60日龄空肠总抗氧化能力显著高于对照组和苏氨酸组（P<0...     

沙引发对紫花苜蓿种子盐逆境下发芽及幼苗生理生化变化的影响

试验以紫花苜蓿品种维多利亚和金皇后种子为材料，研究了沙引发处理对高盐(0．8％NaCl)逆境下种子发芽及幼苗生理生化变化的影响。结果表明，沙引发处理能显著提高紫花苜蓿两个品种种子的发芽率、发芽势、发芽指数和活力指数，缩短平均发芽时间，显著增加幼苗干重，同时提高了过氧化氢酶(CAT)、超氧化物歧化酶(SOD)和过氧化物酶(POD)活性，减少丙二醛(MDA)的积累。说明沙引发提高了紫花苜蓿种子的活力和抗盐胁迫能力，促进了盐逆境下种子的萌发和幼苗生长。     

杂交水稻品种鉴定技术研究

该试验用幼苗形态鉴定法对杂交裟品种进行鉴定。结果表明，通过特定的温度、光照和药剂处理，杂交一代Ｆ１的茎基部呈深红色，而不育系Ａ和保持系Ｂ的茎基部无色或仅呈微红色。故可鉴定出Ｆ１的纯度，但不能将Ａ与Ｂ区分出来。     

A Visco-plastic Model of Magnetorheological Materials

Magnetorheological materials are a class of smart materials whose reological properties may be rapidly varied by application of magnetic field. By a simple mechanical mold, a visco-plastic model for the materials is developed. It is shown that the model can describe the variation of the mechanical properties for the Magnetorheological materials in the different magnetic field. The result is shown that the model can characterize the mechanical properties of Magnetorheological Materials in plastic and viscous variation.     

Data Collection Based on Web Services

To construct data warehouse with heterogeneous, self-governing and distributed database system is a challenge. Two problems have to be solved: one is how to collect data from heterogeneous data sources by an effective method, the other is how to clear up and change the format of the data collected from data sources. The opening and the interact-operation property of Web Services is Analyzed. A Data Collection System based on Web Services, which communicates with heterogeneous data sources with SOAP and HTTP, has been designed. A Data Collector is introduced to clear up and to transform data with composition technology. The pivotal XML technology of transforming and loading up the data are discussed.
