Formaldehyde uye glutaraldehydezvose izvi zvinhu zvinoshandiswa sezvinhu zvinobatanidza zvinhu mumabasa akasiyana-siyana, kunyanya muzvidzidzo zvebhayoloji, kemesitiri, nesainzi yezvinhu. Kunyange zvazvo zvichishanda zvakafanana mukubatanidza zvinhu zvipenyu nekuchengetedza sampuli dzezvipenyu, zvine hunhu hwakasiyana hwemakemikari, reactivity, chepfu, uye mashandisirwo azvo.
Kufanana:
Zvinhu Zvinobatanidza: Zvese formaldehyde uyeglutaraldehyde aldehydes, zvichireva kuti dzine boka recarbonyl (-CHO) pakupera kwechimiro chadzo chemamorekuru. Basa radzo guru nderekuumba zvisungo zve covalent pakati pemapoka anoshanda e biomolecules, zvichikonzera kubatana. Kubatana kwakakosha pakudzikamisa chimiro chesamples dzebiological, zvichiita kuti dzive dzakasimba uye dzisingakanganiswi nekuora.
Mashandisirwo Emishonga Yekurapa: Zvese formaldehyde neglutaraldehyde zvinoshandiswa zvakanyanya mumunda wemishonga yekurapa. Zvinowanzoshandiswa pakugadzirisa nekuchengetedza tsinga muzvidzidzo zvehistology nepathology. Dziviri dzakabatana dzinochengetedza chimiro chadzo uye dzinogona kugadziriswa zvakare kuti dzishandiswe pakuongorora nekuongorora zvakasiyana-siyana.
Kudzora Mabhakitiriya: Mishonga yese ine simba rekuuraya utachiona, zvichiita kuti ive yakakosha mukuuraya utachiona uye mukuuraya utachiona. Inogona kudzima mabhakitiriya, mavhairasi, uye fungi, zvichideredza njodzi yekusvibiswa munzvimbo dzemurabhoritari nemidziyo yekurapa.
Mashandisirwo Emaindasitiri: Zvese formaldehyde uyeglutaraldehydeAnoshandiswa mumaindasitiri akasiyana-siyana. Anoshandiswa mukugadzira manamati, maresini, uye mapolymers, pamwe chete nemaindasitiri ematehwe nemachira.
Kusiyana:
Maumbirwo eKemikari: Musiyano mukuru uripo pakati peformaldehyde neglutaraldehyde uri mumaumbirwo azvo emamorekuru. Formaldehyde (CH2O) ndiyo aldehyde iri nyore, inoumbwa neatomu imwe chete yekabhoni, maatomu maviri ehydrogen, uye atomu imwe yeokisijeni. Glutaraldehyde (C5H8O2), kune rumwe rutivi, ialdehyde yakaoma kunzwisisa, ine maatomu mashanu ekabhoni, maatomu masere ehydrogen, uye maatomu maviri eokisijeni.
Kuitikazve: Glutaraldehyde inowanzoita basa rayo kupfuura formaldehyde nekuda kwecheni yayo refu yekabhoni. Kuvapo kwemaatomu mashanu ekabhoni muglutaraldehyde kunoita kuti ikwanise kubatanidza daro refu pakati pemapoka anoshanda pa biomolecules, zvichiita kuti ikwanise kubatanidza zvinhu nekukurumidza uye zvinobudirira.
Kushanda Zvakanaka Kwekubatanidza: Nekuda kwekuita kwayo zvakanyanya, glutaraldehyde inowanzo shanda zvakanyanya pakubatanidza ma biomolecule makuru, akadai semapuroteni nema enzymes. Formaldehyde, kunyange ichiri kukwanisa kubatanidza, inogona kutora nguva yakawanda kana huwandu hwakanyanya kuti iwane mhedzisiro yakafanana nemamorekuru makuru.
Huturu: Glutaraldehyde inozivikanwa kuva ine chepfu kupfuura formaldehyde. Kugara kwenguva refu kana kuti zvakanyanya mu glutaraldehyde kunogona kukonzera kutsamwa kweganda nekufema, uye inoonekwa senzira yekudzivirira, zvichireva kuti inogona kukonzera allergy mune vamwe vanhu. Kusiyana neizvi, formaldehyde inozivikanwa zvikuru inokonzera kenza uye ine njodzi kuhutano, kunyanya kana ikafemerwa kana kuti ikasangana neganda.
Mashandisirwo: Kunyangwe makemikari ese ari maviri achishandiswa mukugadzirisa masero, anowanzo shandiswa pazvinangwa zvakasiyana. Formaldehyde inowanzoshandiswa pakushandisa histological uye embalming, nepo glutaraldehyde yakakodzera kuchengetedza masero nenzvimbo dzeantigenic muzvidzidzo zve electron microscopy uye immunohistochemical.
Kugadzikana: Formaldehyde inoshanduka-shanduka uye inowanzo shanduka nekukurumidza kupfuura glutaraldehyde. Hunhu uhwu hunogona kukanganisa mashandiro uye kuchengetwa kwezvinhu zvinobatanidza zvinhu.
Muchidimbu, formaldehyde neglutaraldehyde zvakafanana sezvinhu zvinobatanidza zvinhu, asi zvakasiyana zvikuru mumaumbirwo azvo emakemikari, reactivity, chepfu, uye mashandisirwo azvo. Kunzwisisa kwakakodzera misiyano iyi kwakakosha pakusarudza chinhu chakakodzera chinobatanidza zvinhu kune zvinangwa zvakananga uye kuve nechokwadi chekushandiswa kwakachengeteka uye kunobudirira munzvimbo dzakasiyana-siyana dzesainzi, zvokurapa, uye maindasitiri.
