The DPRA (OECD 442C) yog ib qho kev soj ntsuam hauv chemico uas qauv thawj qhov xwm txheej tseem ceeb hauv daim tawv nqaij rhiab heev Txoj Kev Tsis Txaus Siab (AOP) - tawv nqaij, protein ntau reactivity. Cov tshuaj muaj feem cuam tshuam rau qhov ua rau Allergic Contact Dermatitis (ACD) feem ntau yog electrophilic hauv xwm.
Dab tsi yog qhov kev ntsuam xyuas ncaj qha Peptide reactivity?
Saib cov ntsiab lus. Lub DPRA mimics cov txheej txheem ntawm haptenation, piv txwv li covalent khi ntawm cov tshuaj uas tsis muaj molecular hnyav ("haptens") rau cov proteins. Cov txheej txheem no suav hais tias yog ib txoj hauv kev tseem ceeb uas cov tshuaj (los yog lawv cov metabolites) ua antigenic.
Chemico yog dab tsi?
Nyob hauv kev cob qhia. ceeb toom, lub sij hawm nyob rau hauv chemico yog txhais raws li referring. rau " kev siv cov tshuaj abiotic reactivity li . replacements for animal (in vivo) assays". Hauv no.
Kuv tuaj yeem siv Chemico ntawm dab tsi?
Chemico ua tau zoo heev ntawm chav dej thiab chav ua nojxws li da dej, basins, dab dej, vuas, da dej, qhov cub, fridges thiab lub rooj zaum saum. Chemico muaj cov txiv maj phaub roj derivatives thiab glycerine los lubricate, huv si, thiab muab yooj yim yaug nrog dej kais.
Koj puas tuaj yeem siv Chemico ntawm iav?
Chemico tuaj yeem ua tau hloov cov iav dej cim tsis muaj sijhawm. Buff lub paste rau hauv lub khob nrog ib daim txhuam cev thiab tawm rau 10 feeb. Yaug tawm kom pom qhov ua tiav zoo nkauj.

Nyob rau hauv cov qoob loo cog qoob loo xaiv siv nyob rau hauv?
Clonal xaiv yog txoj kev xaiv ntawm kev ntshaw clones los ntawm cov pejxeem sib xyaw ntawm cov qoob loo vegetatively propagated. Nws yog ib txoj hauv kev txhim kho cov qoob loo vegetatively propagated xws li qab zib, txiv tsawb, qos yaj ywm, citrus, txiv nkhaus taw, thiab lwm yam .
