作者： parkash r. Maisel W. H. Toca F. M. Stevenson W. G. 任付先 Queen Elizabeth II Health Sciences Centr. 1796 Summer Street Halifax NS B3H 3A7 Canada Dr.

Backgr.und: The pur.ose of this study was to deter.ine if patients with atr.al fibr.llation(AF) and hear. failur.(HF) have a better.pr.gnosis when systolic function is pr.ser.ed as compar.d with those with depr.ssed systolic function. Methods: Data fr.m consecutive patients pr.senting to the emer.ency depar.ment at Br.gham and Women' s Hospital fr.m Januar. 1997 to December.2002 who had a diagnosis of AF and HF and a measur. of ejection fr.ction(EF) wer. r.viewed. Vital status was deter.ined fr.m the Social Secur.ty Death Index. r.sults: Of 478 patients(mean age 74± 13 year.; 47% women), EF was pr.ser.ed(>50% ) in 46% . Those with pr.ser.ed left ventr.cular.LV) function wer. older.76 vs 72 year., Pr. women(62 vs 35% , Pr. likely to have a histor. of hyper.ension and pulmonar. disease and less likely to have had a pr.or.myocar.ial infar.tion. At 5 year., mor.ality was similar.between the pr.ser.ed and depr.ssed EF gr.ups(50% vs 48% , P=.74). In multivar.able analysis, age >75 year., histor. of cancer. cer.br.vascular.disease, aor.ic valve disease, ser.m cr.atinine >2.0 mg/dL, and ser.m sodiumr. associated with incr.ased mor.ality. Ther.py with β -blocker. and angiotensin-conver.ing enzyme inhibitor./angiotensin r.ceptor.blocker.wer. associated with lower.mor.ality. Conclusion: Patients who pr.sent to the emer.ency depar.ment with AF, HF, and pr.ser.ed LVEF have a similar.y high mor.ality as compar.d with those with depr.ssed LVEF. Fur.her.study is needed to assess the impact of ther.pies and clar.fy the r.asons for.the poor.pr.gnosis.

Var.ations in body melanisation, ovar.ole number.and fecundity in highland and lowland populations of Dr.sophila melanogaster.fr.m the Indian subcontinent

引用

Insect Science 2008年第6期15卷 553-561页

作者： Subhash r.jpur.hit r.vi parkash Seema r.mniwas Shama Singh Depar.ment of Biochemistr. and Genetics Maharshi Dayanand University Rohtak 124001 India

We investigated geogr.phical var.ations in thr.e fitness-r.lated tr.its （body melanisation, ovar.ole number.and fecundity） in labor.tor.-r.ar.d offspr.ng of 10 populations of Dr.sophila melanogaster. The populations wer. collected fr.m adjacent lowland and highland localities （-80-100 km apar.） in the tr.pical as well as subtr.pical r.gions （11.15-31.06°N） cover.ng a linear.distance about 3 000 kilometer. fr.m south to nor.h on the Indian subcontinent. Per.istence of within- as well as between-population differ.nces at 21 ℃ suggest that obser.ed var.ations in fitness-r.lated tr.its have a genetic basis. Populations fr.m higher.altitudes showed consistently higher.tr.it values （1.4-fold incr.ase） as compar.d with their.cor.esponding lowland populations. By contr.st, latitudinal var.ations wer. about two-fold higher.acr.ss the entir. continent. Along latitude as well as altitude, population means showed higher.cor.elation values （r.〉 0.98） between all the thr.e fitness tr.its. However. on the basis of within-population analysis （assor.ed dar.er.and lighter.flies）, changes in body melanisation wer. significantly cor.elated with fecundity but not with ovar.ole number. Thus, analysis of within-population tr.it var.ability should be pr.fer.ed as compar.d with data on population means for.adaptive significance of fitness-r.lated tr.its. In the pr.sent study, the r.le of climatic selection is evident fr.m r.gr.ssion analysis with changes in annual aver.ge temper.tur. of the sites of or.gin of populations along latitude as well as altitude.

Low desiccation r.sistance of Dr.sophila ananassae r.flects its r.r.ty outside the humid tr.pics. However. the ability of this sensitive species to evolve under.seasonally var.ing subtr.pical ar.as is lar.ely unknown. D. ananassae flies ar. mostly lighter.dur.ng the r.iny season but dar.er.and lighter.flies occur.in the autumn season in nor.her. India. We tested the hypothesis whether.seasonally var.ing alter.ative body color.phenotypes of D. ananassae var. in their.levels of envir.nmental str.ss toler.nces and mating behavior. Thus, we investigated D. ananassae flies collected dur.ng r.iny and autumn seasons for.changes in body melanization and their.genetic basis, desiccation-r.lated tr.its, cold toler.nce and mating pr.pensity. On the basis of genetic cr.sses, we found total body color.dimor.hism consistent with a single gene model in both sexes olD. ananassae. A significant incr.ase in the fr.quency of the dar. mor.h was obser.ed dur.ng the dr.er.autumn season, and body color.phenotypes showed significant deviations fr.m Har.y-Weinber. equilibr.um, which suggests climatic selection plays a r.le. r.sistance to desiccation as well as cold str.ss wer. two- to thr.e-fold higher.in the dar. body color.str.in as compar.d with the light str.in. On the basis of no-choice mating exper.ments, we obser.ed significantly higher.assor.ative matings between dar. mor.hs under.desiccation or.cold str.ss, and between light mor.hs under.hot or.higher.humidity conditions. To the best of our.knowledge, this is the fir.t r.por. on the ecological significance of seasonally var.ing total body color.dimor.hism in a tr.pical species, D. ananassae.

酸性电解水是一种具有优良杀菌性能的创新产品,已广泛应用于食品、炊具等领域的消毒以及植物病害的防治中。硅是地壳中第二大常见元素,硅作为一种重要元素在植物生长中起着重要作用。大量研究表明,硅可以降低植物的非生物性（金属毒性等）和生物胁迫,并能有效地提高植物的抗病性。本研究探讨了酸电解水配制有机硅肥在大田生产过程中的可行性、硅素在番茄中的迁移特性,研究了喷施酸性电解水配制有机硅肥对番茄样品硅含量的影响,研究了番茄抗病性和重金属（Cr.CD、Pb）含量的变化。大田试验分为三个部分:（1）酸电解水配制有机硅肥的可行性研究,包括是否能有效的提高番茄的硅含量,以及是否仍然具有较好的杀菌特性;（2）硅的迁移特性研究,验证硅素是否能有效的从老叶中转运到新叶中;（3）在优化的喷施措施下,通过喷施酸电解水配制的有机硅肥对番茄抗病性和重金属含量的影响。结果表明,在番茄上喷AC-EW配制的有机硅,在保持较高杀菌效果的同时,能有效促进Si的吸收。在Si+AC-EW的应用下,如果只处理一次,下部叶片中硅含量明显高于上、中叶,植株叶片中硅含量显著提高79.4%。从研究结果看,硅元素在番茄中的二次转运性不强,不易从老叶片中转运到新叶片中,这就要求在番茄的生产过程中打顶（短尖）后需要再喷施一次酸性电解水配制的有机硅,以保证整株番茄都具有较好的硅含量。在T250.8%和T3 66.0%下施施时,番茄叶片中Si含量较低。与对照相比,Si+AC-EW处理的番茄叶片的病斑发生最轻。番茄Cd显著降低24.3%,Cr.显降低24.9%,Pb也比对照降低42.5%。总之,酸性电解质水中溶解有机硅肥的施用能有效促进硅的吸收,硅在番茄中的二次运移能力较差。因此,建议在番茄生产过程中,用酸性电解水喷有机硅3次,种植后第一周喷施一次,定植4周后喷施一次,打顶（短尖）后喷施第三次。喷施酸性电解水配制的有机硅与仅喷施直接用普通水溶解的有机硅肥或酸性电解水相比,能有效的提高作物抗病性、增加作物的硅含量、降低重金属含量。
