Rau zaub mov, nplej, pub txhawm rau txheeb xyuas mycotoxins Cov lus qhia tshwj xeeb: 96T / lub thawv
Kev xeem T2 yog dab tsi? T2 Cov Khoom Siv Ceev Ceev yog qhov nrawm, ib qib ntsuas rau qhov muaj txiaj ntsig zoo (lossis muaj nuj nqis) kuaj pom T2 hauv tsiaj pub thiab
nplej (nplej, txhuv nplej, txhuv, txiv maj phaub, millet, hmoov). Lub sijhawm ntsuas tag nrho yuav siv 8 feeb.
Tau Txais Tus Nqi Pub Dawb! T2 toxin yog dab tsi? 1. Txhais T-2 toxin yog ib qho ntawm trichothecenes (TS) sib xyaw ua los ntawm ntau hom kab mob, feem ntau yog Fusarium trichocarpa. Nws yog dav faib nyob rau hauv qhov. Nws yog ib yam tshuaj lom uas ua paug rau cov qoob loo thiab khaws cov nplej, ua teeb meem rau tib neeg thiab tsiaj txhu.
Hauv kev sib tham ua ke ntawm United Nations Food and Agriculture Organization (FAQ) thiab World Health Organization (WHO) hauv Geneva xyoo 973, hom tshuaj lom no, zoo li
tshuaj aflatoxin , tau suav hais tias yog qhov txaus ntshai tshaj plaws ntawm cov zaub mov tsis huv nyob rau hauv xwm. Tom qab Nyab Laj siv cov tshuaj "daj nag" (uas muaj T-2 toxin) nyob rau sab Asia sab hnub tuaj, kev phom sij ntawm T-2 cov tshuaj lom rau tib neeg kev noj qab haus huv tau ua rau muaj kev txhawj xeeb loj ntawm cov kws tshawb fawb los ntawm thoob plaws ntiaj teb. Ntau qhov kev tshawb fawb tau ua tiav ntawm cov tshuaj lom ntawm cov tshuaj lom.
2. Yam ntxwv T2 Lub phaus molecular ntawm
T-2 tshuaj lom yog 466.51, thiab lub npe tshuaj lom yog 4,15-diacetoxy-8- (isovaleryloxy) -12,13-epoxytrichothecene-9-ene-3 -Alcohol, nyob rau hauv uas cov pa oxygen thiab ob daim ntawv cog lus yog nws qhov chaw nquag, thiab qhib lub nplhaib oxygen lossis txo ob daim ntawv cog lus tuaj yeem txo nws cov tshuaj lom. T-2 toxin yog ib rab koob dawb zoo li siv lead ua, uas ruaj khov nyob hauv chav sov. Cov tshuaj lom tsis txo qis tom qab muab tso rau 6-7 xyoo lossis ua kom sov txog 100-120 ℃ rau 1 teev. T-2 toxin muaj pawg ester, uas yog hydrolyzed rau cov dej cawv sib xws tom qab kho nrog alkali.
Muaj tsawg daim ntawv tshaj qhia txog T-2 tshuaj lom lom los ntawm nqus tau los ntawm txoj hlab ua pa. Qhov laj thawj tseem ceeb rau tshuaj lom yog qhov tshuaj lom T-2 muaj qhov nqus tau zoo los ntawm mucosa, thiab tuaj yeem ua kom ncaj qha rhuav tshem cov hlab ntsha ntawm mucosa thiab nce nws cov permeability. Cov tshuaj lom T-2 lom rau tsiaj sib txawv muaj qee hom tsiaj sib txawv. Cov menyuam mos los yog menyuam yaus muaj menyuam yaus nkag tau rau cov tshuaj lom ntau dua li cov tsiaj laus.
3. T2 Cov teebmeem lom T-2 cov tshuaj lom feem ntau ua rau cov nqaij thiab cov kabmob nrog lub zog sib faib ntawm tes, xws li thymus, pob txha pob txha, daim siab, tus po, qog ntshav, gonads thiab lub plab hnyuv mucosa, thiab txwv tsis pub cov protein thiab DNA hauv cov kabmob no. Ib qho ntxiv, nws kuj tau pom tias cov tshuaj lom tuaj yeem ua rau DNA ib leeg tawg hauv lymphocytes. T-2 tshuaj lom kuj tseem tuaj yeem ua rau ntau qhov chaw ntawm oxidative phosphorylation thiab ua rau lub ntsws ua pa nyuaj siab.
T2 kev phom sij txaus ntshai Trichothecenes, lom heev
mycotoxin tsim los ntawm Trichothecium spp lossis Fusarium spp. Nws tuaj yeem ua rau muaj ntau yam tsos mob ntawm tshuaj lom rau tib neeg lossis tsiaj txhu, feem ntau ntuav, tsis kam noj, mob plab zom mov, mob o, mob txhab ntshav, thiab cov tsos mob ntawm lub paj hlwb. T-2 toxin yog teratogenic thiab tsis muaj zog carcinogenic. Nws feem ntau ua rau cov tsiaj cov kabmob hematopoietic (txwv tsis pub rov tsim dua tshiab hematopoietic ua haujlwm ntawm cov pob txha pob txha thiab tus po), lub cev tiv thaiv kab mob (txo qis kev ua haujlwm tsis muaj zog), lub plab zom mov (ua rau hemorrhage thiab necrosis ntawm lub plab zom mov), thiab lub paj hlwb thiab lub cev ua haujlwm, thiab lwm yam.
Nws yog ib qho mob epithelial necrosis uas tuaj yeem ua rau mob necrosis thiab ua rau tawv nqaij ntawm epithelium ntawm daim tawv nqaij, qhov ncauj kab noj hniav thiab lub plab zom mov sab saud. Nws muaj qhov ua kom tsis muaj zog tiv thaiv npua, ua rau lymphopenia, txo qis cov ntshav protein ntau ntau, ua rau lub plab zom mov, thiab hloov pauv hauv daim siab thiab ob lub raum. Ib qho ntxiv, nws tuaj yeem ua rau kev hloov pauv ntawm tes thiab kev hloov pauv.
1. T2 toxin hauv npua Cov tsos mob ntawm tus kab mob porcine T-2 lom lom feem ntau yog mob plab, tsis qab los noj mov, kev loj hlob qeeb, qhov txhab ntawm qhov ncauj thiab tawv nqaij, ntuav, thiab tiv thaiv kab mob.
2. T2 toxin hauv nqaij qaib Nqaij qaib T-2 tshuaj lom pom pom qis qe qe ntau lawm, qe qe tsis zoo, tsim cov plaub tsis sib xws, ua rau lub qhov txhab, tsis qab los lossis txawm tias raug tshem tawm, dyskinesia, thiab tsis muaj kev tiv thaiv. Cov kev tshawb fawb tau pom tias gavage ntawm 10-20μg/me nyuam qaib rau lub sijhawm ntev tuaj yeem qhia qhov tseem ceeb atrophy ntawm lub cev tiv thaiv kab mob xws li hnoos qeev, thymus thiab bursa ntawm Fabricius. Cov nqaij qaib tom qab T-2 cov tshuaj lom lom tau yooj yim kis los ntawm
Salmonella thiab
Tus kab mob Newcastle tus kab mob.
Cov kev tshawb fawb tau qhia tias thaum cov ntsiab lus T-2 tshuaj lom nyob rau hauv pub mus txog 8 mg/kg, qe ntau lawm ntawm tso hens txo qis. Thaum cov ntsiab lus T-2 tshuaj lom nce mus txog 20 mg/kg thiab pub rau 2 lub lis piam, cov qe ntau lawm txo los ntawm 20%, thiab cov qe nyias nyias tau nce ntau.
Cov yam ntxwv ntawm T2 xeem 1. 8 feeb nyeem cov txiaj ntsig
Txoj kev kuaj pom T2 xeem T2 Cov Khoom Siv Ceev Ceev yog colloidal kub immunochromatography kuaj uas pom t2 seem hauv cov nplej,
pub thiab ua tau raws li EU MRL. BALLYA cov khoom siv ntsuas kub kub colloidal tuaj yeem ua tau raws qhov xav tau ntawm lub tshav pob, thiab ua tiav tsis pub dhau 5-10 feeb, thiab tuaj yeem ua tau zoo lossis muaj txiaj ntsig nrog kev nkag siab siab.
Cov khoom no siv cov txheej txheem sib tw kub sib xyaw kom pom sai sai ntawm T2 cov tshuaj lom hauv cov nplej thiab txau los ntawm cov tshuaj tiv thaiv kab mob antigen-antibody tshwj xeeb. Nws yog qhov tsim nyog rau ntawm qhov chaw tshawb xyuas sai ntawm ntau lub tuam txhab, kuaj cov tsev haujlwm thiab saib xyuas haujlwm.
Qauv rau kev xeem T2 Cov qoob loo uas muaj feem cuam tshuam rau T-2 muaj xws li pob kws, nplej, barley, oats, txhuv thiab rye.
Tshawb nrhiav qhov txwv rau kev xeem T2 LOD tuaj yeem hloov pauv raws li qhov xav tau lossis qhov txawv ntawm qhov sib txawv, thov mus saib hauv phau ntawv qhia kom paub meej ntxiv.
Qhov tseem ceeb ntawm kev xeem T2 Kev xeem T2 tuaj yeem pab cov tuam txhab tsim khoom, cov koom haum tswj hwm, thiab cov pej xeem saib xyuas cov khoom lag luam zoo thiab pab tib neeg tiv thaiv lawv txoj kev noj qab haus huv.
