Effects of Three Drugs on Membrane Metabolism Against Cysticerci cellulosae in vitro

To investigate the effects and mechanisms of the benzimidazole carbamate and benmidine drugs on Cysticerci cellulosae and choose effective drugs on Cysticerci cellulosae, the membrane metabolism of Cysticerci cellulosae in vitro was tested after three kinds of drugs which were used respectively. The indexes included the contents of lipids, the contents of SA and the changes of the membrane fluidity. The results showed that oxfendazole could inhibit the membrane metabolism of immature and mature Cysticerci cellulosae in vitro, and albendazole only inhibited the mature one, while thibendimidine neither acted on the immature nor mature one.     

晚熟鲜食桃优良新品种八月香选育研究

１９９４年，从豫白和搬口白的杂交后代中选育出晚熟鲜食桃优良新品种八月香。其果实发育期１３０ ｄ，在郑州地区成熟期为８月２０日左右。果实近圆形，向阳面着鲜红到紫红色晕。平均果重１６８ ｇ，最大果重２８６ ｇ，果肉乳白色、硬溶质，风味浓甜，有香味，品质极上。丰产、稳产、耐贮运，具有较强的抗逆性。近年来已在全省范围内推广，新疆、四川、湖南、广西、浙江、山西、河北等省已引种栽培。

本文根据１９８６年４～８月在乌鲁木齐雅玛里克山（９０余号）及校园内捕获的（１８只）Ａｌｓｏｐｈｙｌａｘｐｉｐｉｅｎｓ，观察得知其产卵在５～６月，每次产卵一枚，卵壳系钙质，性成熟在出生后第三年。瞳孔圆形，强光下呈垂直线状。动食性，卞要以昆虫、蜘蛛及蝎子为食。     

Quantitative site classification in the key county in the conversion of farmland to forests project

According to the requirements of the conversion of farmland to forests project (CFFP), we investigated the vegetation factors and environmental factors from more than 6,105 sub-compartments in Liangcheng County, Inner Mongolia by using the Matlab, analytic hierarchy process (AHP), and the hierarchical cluster method (HCM). The site conditions were classified quantitatively. The results show that CFFP at this site comprises five site-type groups and 19 site types. A quantitative site classification system method has been established in this paper. __________ Translated from Journal of Beijing Forestry University, 2005, 27(6) [译自: 北京林业大学学报, 2005, 27(6)]     

红星苹果和肥城桃果实软化的酶学基础

以红星苹果穴Malusdomesticacv.Starking雪和肥城桃穴Prunuspersicacv.Feicheng雪果实为试材,结合乙烯利和1-甲基环丙烯(1-MCP)处理,分别研究了2者软化的酶学基础,并就其差别作了探讨。结果表明:红星果实软化中起主要作用的酶为内切和外切多聚半乳糖醛酸酶(endo-和exo-PG);肥城桃果实软化的前20d则以纤维素酶(EGase)为主,20d后软化以endo-PG为主。研究同时发现,脂氧合酶(LOX)在这2种果实软化的启动阶段都起了明显的促进作用。1-MCP通过对红星果实中PG、肥城桃果实贮藏前期EGase和后期endo-PG活性的抑制,以及对2者软化启动阶段LOX活性的抑制,延缓了果实硬度的下降。
