英国研发出手术蜂蜜可治疗创伤杀灭超级细菌据英国媒体报道,英国科学家研发出一种手术蜂蜜,具有治疗伤口与感染的神奇效果。据报道,目前英国罕普夏(Hampshire)地区一些医院已使用手术蜂蜜(Surgihoney)治疗婴儿、产妇、癌症患者以及老人,时间长达1年多。用手术蜂蜜来治疗伤口和溃疡,包括超级细菌抗药性金黄色葡萄球菌(MRSA)感染的伤口,都能够在几天内痊愈;此外,剖腹产伤口感染的妇女人数也因此减半。这款蜂蜜也能治疗面疱,以及军人的伤口,还可用来保护癌症病患置放化疗导管的皮肤。英国国家医疗保健服务信托基金(NHSFoundaionTrust)顾问、微生物学家德莱登(MatthewDryden)博士表示,这款超级蜂蜜,将为全世界的伤口治疗带来革命性影响。德莱登博士说,我发现手术蜂蜜在治疗各种细菌上成效更好,因此过去1年来,我都用来治疗患者,效果很惊人。他说,有很多产品能杀死细菌,但通常无助修复组织。蜂蜜是很神奇的天然药物,在杀死细菌的同时,却又不会破坏组织。目前英国药物及保健产品管理局已批准这款蜂蜜,但尚未上市。Doctorsdiscover'superhoney'withamazingpowertotreatsoldiers'woundsandkillsuperbuginfectionsSurgihoneyhasbeentestedinHampshirehospitalsforayearWounds,ulcersandMRSAhealedwithindaysthankstothehoneyAnewhoneyhasbeenproducedthathashad‘amazing’resultstreatingwoundsandinfections.Thebio-engineeredproductSurgihoneywastestedonbabies,newmothers,cancerpatientsandtheelderlyforoverayearinHampshirehospitals.Woundsandulcers,includingthoseinfectedwiththesuperbugMRSA,healedwithindays,whilethenumberofwomenwhosufferedinfectionsaftergivingbirthbycaesareansectionhashalved.IthasalsohealedthewoundsofsoldiersreturningfromAfghanistan,andbeenusedtotreatacneandtoprotecttheskinofcancerpatientsfittedwithacatheterforchemotherapy.DrMatthewDryden,consultantmicrobiologistattheHampshireHospitalsNHSFoundationTrust,said:‘Itwillrevolutionisewoundcarearoundtheworld.’Honeyhasbeenusedforitshealingpowersforthousandsofyears,althoughdoctorsfavourpenicillinandantibiotics.However,Surgihoney,whichisstoredin10gsachets,cankillbacteria,parasitesandfungalinfectionswhilealsoencouragingwoundstoheal.DrDrydensaid:‘Ihaveconductednumerouslaboratorytestsandcompareditwithhoneysfromaroundtheworld.‘IfoundSurgihoneybetterfortreatingeverytypeofbug.SoforthepastyearIhavebeenusingitonpatientsandtheresultshavebeenamazing.More...Nailvarnish,batteriesandglue:HowBritonsarestuffingtheirfridgeswithobjectswhichhavenoneedtobethereThe£20jarofhoneythatneedsasecuritytagtodetermiddle-classshoplifters'Thereareplentyofproductsthatcankillbacteriabuttheyoftendon’thelphealtissue.‘Honeyisafantasticnaturalmedicine.Theimportantextraisthatitkillsthebugsbutdoesn’tdamagethetissue.’Effective:ThehoneyhashelpedpatientssufferingfromMRSASurgihoneyisbeingdevelopedbyIanStaples,abusinessmanwhoonceownedtheHalfordsmotoraccessorieschain.HeboughtanorganicfarminsouthernChile,setupbeehivesthenfundedscientificresearchersinIrelandtoidentifytheuniquehealthelements.ThehoneyhasbeenlicensedbytheMedicinesandHealthcareproductsRegulatoryAuthorityintheUKbutisnotyetcommerciallyavailable.Readmore::@MailOnlineonTwitter|DailyMailonFacebook荔枝防腐保鲜剂和保鲜方法获国家发明专利从中科院华南植物园获悉,由华南植物园科研人员完成的一种荔枝防腐保鲜剂和荔枝防腐保鲜方法近日获得了国家发明专利授权,为较长时间保存荔枝这种岭南佳果的色、香提供了新方法。据介绍,荔枝由于在盛夏高温季节采收,加上其结构特殊,采收后极易褐变和腐烂变质。在常温下,荔枝果实2~3天即褐变腐烂,失去商品价值。采后腐烂是限制荔枝长期贮运、导致货架寿命短及果实商品价值下降的主要因素之一。目前,用于荔枝腐烂控制的防腐剂处理、二氧化硫处理、热处理等方法对保鲜荔枝有一定效果,但均存在对人体有潜在危害且保鲜效果不佳等缺陷。为此,华南植物园段学武、蒋跃明等科研人员开发出了一种简单易行且又高效的荔枝贮运防腐保鲜技术。据介绍,该发明公开了一种荔枝防腐保鲜剂和荔枝防腐保鲜方法。保鲜剂按总质量分数100%计,包括有机硅季铵盐(HM98)0.5%~2%,杀菌剂0.05%~0.1%,余量为水。其中,杀菌剂为多菌灵、抑霉唑、施保克中的一种或两种的组合。荔枝防腐保鲜方法是选择晴天采收、八至九成熟、无机械损伤和病虫害的荔枝果实;将荔枝果实浸泡于荔枝防腐保鲜剂中,然后预冷、包装、贮藏。实验结果显示,利用此方法,在2℃~4℃贮藏条件下,荔枝果实30天后腐烂率在5%以下。澳大利亚科学家发明微波杀虫技术食品伙伴网讯据外媒报道,近日澳大利亚科学家发明了利用微波或高能粒子杀死新鲜水果和蔬菜中害虫的技术,该技术可以代替杀虫剂,消除杀虫剂的健康隐患。据了解,昆虫和病原体对农作物的侵害使澳大利亚农业每年损失数亿澳元,例如,2003至2008年间,澳大利亚政府和农业行业就花费了1.28亿澳元用于控制最具破坏性的害虫之一的果蝇。澳大利亚联邦科学与工业研究组织最近研制出了微波杀灭苹果、牛油果、大辣椒和西葫芦中的昆虫和昆虫卵的先进技术。蔬菜与水果在经过该机器的传送带时,受到微波的照射。研究人员表示,他们正在找寻能够杀死不同的害虫但仍然保持蔬菜、水果品质的温度范围。他们在研究中发现有些温度非常有效,达到了100%的杀死害虫。而且将这种微波用于苹果的最初试验评估发现,这种微波杀虫技术可以延长产品的保质期,对出口海外的销售者非常有利。生物安全专家巴罗(PaulDeBarro)博士说,澳大利亚农民需要不使用杀虫剂杀死害虫的替代方法,以在国际与国内市场上保持竞争力。澳科学与工业研究组织正在研究几项其它的无化学品杀虫与杀菌技术,包括冷等离子,即用带电气体冷冻种子表面的真菌和细菌,以及高压处理等杀虫与杀菌的手段。TheCSIROhasinventedmachinesthatusemicrowavesorhigh-energyparticlestokillinsectsandpestsinsidefreshfruitandvegetables.Whilethetechnologiessoundlikescience-fiction,theyreplacethefarmers'needtousetoxicchemicalsandinsecticidesonproduceafterithasbeenharvested.Thechemical-freedevicesaretimely,giventhatthegovernment'schemicalregulatorhassuspendedtheuseofseveralofthemostpopularinsecticidesbecauseofthethreattopublichealth.Insectsandpathogensthatattackcropscosttheindustrymillionsofdollarseachyear.Industryandgovernmentspentmorethan$128millionmanagingfruitflies,oneofthemostdevastatingpests,between2003and2008.PaulDeBarro,oftheCSIRO'snewBiosecurityFlagship,saidthegroup'smostadvancedtechnologyusedmicrowavestokillinsectsandtheireggsinsidecropssuchasapples,avocadoes,capsicumsandzucchinis.Fruitorvegetableswereexposedtomicrowavesastheymovedthroughthemachineonaconveyorbelt.Theprojectleader,MalaGamage,saidtheteamwasestablishingtheheatingrangesrequiredtokilldifferentinsectswhilemaintainingthequalityofthefruitorvegetable.''Someofourheatingprotocolswereveryeffective,andwewereabletoget100percentmortality,''DrGamagesaid.Aninitialtrialtoevaluatethetechnologyonapplesfoundthemicrowavetreatmentmayalsoprolongtheshelflifeoftheproduce,abigadvantageforsellersexportingthei
