乌饭树叶及色素微量元素的研究

本文对乌饭树叶及其色素中的微量元素进行了研究。结果表明:乌饭树老叶、嫩叶及其色素中均含有19种微量元素;嫩叶及其色素中的Fe、Mn和Zn含量比老叶多,老叶中Zr、Ba、Mn和Ti的相对含量较高,嫩叶中Fe、Mn、B和Zn的相对含量较高;老叶、嫩叶及其色素中均未检出对人体有毒的元素As。

Use of Vaccinium octoploids to facilitate 4x-6x gene transfers

The use of an 8x Vaccinium produced through doubling a tetraploid hybrid with colchicine was studied as a means of facilitating gene exchange between V. corymbosum L. and V. ashei Reade. Analysis included meiotic observations and crossability studies of the 8x plant, as well as attempting to develop 6x breeding lines. Meiotic analysis revealed the presence of micronuclei in Telphase II products and polyspory in sporads. In the crossability studies five 4x highbush plants were pollinated with 8x o2 4x pollen. Data gathered included: % fruit set, average weight/fruit, average number of seeds/fruit, average number of seedlings/pollination, and number of 6x seedlings. Octoploid pollinations were significantly lower than 4x pollinations in all parameters. One 6x plant was produced from the 4x-8x crosses but was found to be mitotically unstable, having somatic cells with chromosome numbers ranging from 48 to 168.     

红豆越桔的调查研究

作者对长白山和大兴安岭地区的红豆越桔(Vaccinium vit is-idaea)的种类、生长习性、生态环境等进行了调查研究。大兴安岭的红豆越桔有高株和矮株两种类型,长白山的则主要为矮株型。红豆越桔的地下部由行茎、根态茎和根系三部分组成,分布在25cm以上的土层中。在自然条件下红豆越桔的地上单株可生活约13年。红豆越桔喜有机质丰富、湿润、酸性土壤,喜光、抗寒,但早春霜冻易使其花器受害。     

用中药辅助治疗犬瘟热临床效果研究

 将上海五家宠物医院2011年就诊的321只犬瘟热病犬随机分成两组,第一组124只,肺炎型60只、胃肠炎型34只和混合型30只,采用常规西药治疗。第二组197只,肺炎型91只、胃肠炎型56只和混合型50只,参考甲型H1N1流感治疗方案,在常规西药治疗的基础之上根据症状分型进行中药辅助治疗。分组治疗结果显示,肺炎型、胃肠炎型和混合型第二组比第一组治愈率分别高22%、22.6%和17.3%;随机选取其中68只,取治疗前和治疗7 d后的鼻液进行斑点杂交检测CDV;斑点杂交结果显示,第二组治疗方法治疗后的阳性率下降50%,第一组方法治疗后的阳性率下降30%。试验结果表明,中药辅助治疗可有效地增加犬瘟热的临床治愈率。
