Kev taw qhia rau lub npe thiab lub tswv yim ntawm "Romanowsky stains" yog ua raws li cov lus qhia luv luv ntawm cov dyes koom nrog thiab tshwj xeeb tshaj yog lub luag haujlwm tseem ceeb ntawm azure B thiab ntawm impurity ntawm feem ntau cov khoom lag luam dye.Cov yam ntxwv ntawm cov qauv thiab cov tsoos Romanowsky stains tau piav qhia, piv txwv li, tus naj npawb thiab qhov sib piv ntawm cov kua qaub thiab cov xim yooj yim siv, cov teebmeem hnyav, lub sijhawm staining, thiab cov teebmeem kho.Lub peculiar zoo ntawm Romanowsky staining yog sau tseg, uas yog, lub polychromasia ua tiav nyob rau hauv ib tug technically yooj yim yam uas muaj peev xwm rau stain intensification ntawm "xim liab."Cov nyiaj tau muab los ntawm ntau yam ntawm cov ntsiab lus physicochemically cuam tshuam, uas yog, acidic thiab yooj yim dyeing, peculiarities ntawm acidic thiab yooj yim dye mixs, qhov tshwm sim ntawm qhov sib txawv staining tus nqi ntawm cov xov tooj ntawm tes thiab cov ntaub so ntswg sib txawv thiab cov xim sib txawv, cov tshuaj tseem ceeb ntawm "cov xim liab. , "lub substrate selectivity rau liab doog xim tsim thiab nws intensification nyob rau hauv situ vim ib tug template nyhuv, los ntawm resin embedding thiab ua ntej fixation.Raws li cov physicochemical phenomena, mechanisms rau ntau yam Romanowsky staining daim ntaub ntawv tau piav qhia nrog rau cov ntshav, pob txha thiab cytological smears;G-bands ntawm chromosomes;kab mob thiab lwm yam kab mob ib leeg;thiab paraffin thiab resin cov ntaub so ntswg.Cov feem ntau koom nrog hauv cov txheej txheem tshwj xeeb no tau rub ua ke los tsim kom muaj "universal" generic mechanism rau cov stains.Qee qhov teeb meem ntawm Romanowsky stains tau tham nrog rau kev tsis sib haum xeeb ntawm kev daws teeb meem ntawm acidic dye-basic dye mixtures, inherent heterogeneity ntawm polychrome methylene xiav, thiab cov teeb meem tshwm sim ntawm standardization.Thaum kawg, lub tswv yim daws teeb meem daws teeb meem yog txuas ntxiv.
