Hematoxylin -eosin uas tseg tau (hematoxylin-eosin uas tseg tau), xa mus rau raws li nws tseg tau, paraffin seem technology kheev siv nyob rau hauv ib tug ntawm cov dyeing txoj kev. Hematoxylin yog alkaline, mas nyob rau hauv lub nucleus ntawm cov chromatin thiab lub cytoplasm ntawm lub ribosomes ntshav xiav; liab rau lub acid zas, lub ntsiab cytoplasm thiab extracellular matrix nyob rau hauv nyob tus yeees ntawm liab. NWS uas tseg tau yog lub feem ntau yooj yim thiab feem ntau lug siv cov txheej txheem nyob rau hauv histology, embryology, pathology qhia thiab kev tshawb fawb.

Zas qob kev faib:
Cov khoom uas yog ib qho yooj yim yuav tsum tau dawb lias los ntawm alkaline los yog acidic dyes yog hu ua basophilia thiab acidophilia, thaum qe thiab cov kua qaub dyes muaj zog sib ze li neutrophilia.
Cov nqaijrog nyob rau hauv cov ntaub so ntswg roos ib tug ntau ntawm cov amino acids nyob rau hauv lub protein, thiab lawv muaj ntau isoelectric cov ntsiab lus. Nyob rau hauv qhov dog dig dyeing txoj kev, lub pH nqi ntawm cov dyeing kua yog hais txog pH6, lub intracellular acidic tshuaj xws li cov chromatin ntawm lub nucleus, cov ntxhib endoplasmic reticulum thiab cov Nissl lub cev nyob rau hauv lub caj pas hlwb thiab hlab ntsha hlwb yog tsuas nrog alkaline dyes, hu basophilic. Thiab lwm yam cov nqaijrog nyob rau hauv lub cytoplasm, xws li cov ntshav liab nyob rau hauv hemoglobin, eosinophils hais thiab collagen fibers thiab nqaij fibers yog tsuas los ntawm acid dyes, cov tshuaj lub npe hu ua eosinophilic. Yog hais tias koj hloov lub pH ntawm lub dyeing tshuaj, pH nqi nce, tus thawj acid dyes yuav hloov dua siab tshiab rau hauv tshuaj ntawm basophilic alkalinity; pH yuav txo tau, tus thawj dyestuff dyeing ntaub ntawv uas yuav ua eosinophilic. Yog li ntawd hais tias cov pH nqi ntawm cov uas tseg tau cov tshuaj yuav ua rau lub dyeing cov tshuaj tiv thaiv.
Deoxyribonucleic acid (DNA) nyob rau hauv ob chains ntawm lub phosphate pab pawg neeg sab nraud, nrog rau ib tug tsis zoo xwb, acidic, nws yog ib qho yooj yim thiab zoo them hematoxylin dyes nrog ion tsevneeg thiab tsuas. Hematoxylin yog xim xiav nyob rau hauv cov kua alkaline, li ntawd, lub keeb yog tsuas xiav. Eosin Y (tetrabromofluorescein) yog ib tug sib tsim acid zas xim uas dissociates rau hauv ib tug zoo them anion nyob rau hauv dej thiab binds mus rau lub zoo them ntawv ntawm cov protein yuav ua rau lub cytoplasm, cytoplasm, erythrocyte, nqaij, connective nqaij, eosinophils, thiab lwm yam yog dyed nyob rau hauv txawv degrees ntawm liab los yog liab, nyob rau hauv ntse sib piv rau lub xiav nuclei. Euphorbia yog ib tug zoo zas xim rau cytoplasm.
Vim qhov sib txawv muaj pes tsawg leeg ntawm lub koom haum los yog lub hlwb nyob rau hauv lub hematoxylin affinity thiab dyeing zog yog tsis tau tib yam. Tom qab hematoxylin uas tseg tau, lub nucleus thiab calcium ntsev hnoos qeev thiab lwm yam xiav, muaj hydrochloric acid cawv ntau yam zoo thiab tsis muaj zog alkaline tov yog xiav, xws li cov uas tsim nyog kho mob, yuav ua rau lub nucleus meej maub xiav, cytoplasm thiab lwm cov khoom xyaw decolorization. Thiab ces cov kev siv ntawm cytoplasmic zas Euphorbia cytoplasm, yog li ntawd lub ntau yam ntawm cov cytoplasm thiab qhia ib tug txawv tob ntawm txawv liab. Yog li ntawd ib tug ntau yam ntawm cov ntaub so ntswg los yog cell Cheebtsam thiab txhab ntawm lub dav morphological qauv yuav tsum displayed.
Uas tseg tau tau:
Lub nucleus yog tsuas nrog hematoxylin rau hauv kaj xiav, cov pob txha mos matrix, calcium ntsev hais tau maub xiav, hnoos qeev yog grey xiav. Lub cytoplasm yog tsuas nrog txawv ntxoov liab mus liab, thiab lub eosinophilic hais nyob rau hauv lub cytoplasm yog liab. Collagen fiber yog daj ntseg liab, elastic fiber yog kaj liab, ntshav liab twb txiv kab ntxwv, protein kua yog liab.
Lub coloring yog hais txog mus rau lub hom ntaub so ntswg los ntawm tes, thiab kuj hloov nrog nws lub neej voj voog thiab pathological kev hloov. Piv txwv li, muaj ntau yam hlwb nyob rau hauv lub nascent lub sij hawm ntawm cytoplasm rau cov liab xim ntawm lub teeb los yog ib nyuag basophilic, thaum nws laus los yog sib hloov yog eosinophilic uas tseg tau. Collagen fibers nyob rau hauv txoj kev laus thiab pob tshab denaturation, lub xim liab los ntawm ntiav rau sib sib zog nqus.
