Histological kuaj yog kev kawm morphological ntawm cov ntaub so ntswg thiab kabmob. Nws suav nrog kev kuaj ntshav biopsy thiab ntsuas cov khoom tau txais thaum lub sijhawm phais.
Qhov kev sim no yog rau kev kuaj mob thiab kho lub hom phiaj. Nws yog ib txoj hauv kev tseem ceeb rau kev kuaj mob qog noj ntshav, nrog rau txoj hauv kev los txiav txim siab qhov ua tau zoo ntawm kev kho mob mus tas li.
Yuav ua qhov kev kuaj mob histological, lawv nqa cov khoom thiab npaj rau hauv ib txoj hauv kev rau kev kawm. Tom qab ntawd, ua tib zoo saib xyuas lub microscopy, nrog rau kev ntsuas qhov zoo thiab qhov ntau ntawm cov duab tau.
Lub ntsiab lus ntawm kev tshuaj xyuas yog cov kev npaj histological npaj los ntawm cov qauv ruaj khov. Cov no muaj xws li smears, prints, films fabrics, as well as their thin sections.
Rau qhov tsim khoom ntawm kev npaj histological, cov khoom tsim nyog raug coj mus, tsau, compacted, ntu tau npaj, stained lossis sib piv. Cov theem no dhau los ntawm kev npaj uas tau kawm siv electron microscopy. Yog hais tias ib qho kev kuaj histological tau ua nrog lub teeb orthoscope, ces qhov taucov seem yuav tsum tau muab kaw rau hauv ib lub balm los yog lwm yam pob tshab nruab nrab.
txhawm rau tshuaj xyuas cov kev npaj no, siv ntau hom tshuab ntsuas: lub teeb, kis tau tus mob, scanning, electron, ultraviolet thiab luminescent, nrog rau theem sib piv. Lub tom kawg tso cai rau saib cov duab sib piv ntawm cov khoom pob tshab uas tsis tuaj yeem pom nrog cov khoom siv microscopy.
Nws yog ib qho tsim nyog sau cia tias thaum kuaj histological tau qhia, cov khoom tuaj yeem raug coj los ntawm kev tswj xyuas qhov muag (thaum kuaj pom ntawm daim tawv nqaij lossis pom cov mucous membranes), thiab tseem ua los ntawm txoj kev tshwj xeeb (sab hauv. biopsy). Yog li, cov ntaub so ntswg rau kev tshawb fawb tuaj yeem nqa nrog rab koob, los ntawm kev nqus, pob txha trepanation.
Tseem tseem muaj lub tswv yim ntawm kev tsom mus rau biopsy, thaum cov ntaub so ntswg rau kev kuaj tau raug coj los tswj kev pom kev siv cov khoom siv kho qhov muag tshwj xeeb lossis siv ultrasound.
Nws tsim nyog sau cia tias txhawm rau txhawm rau kuaj histological kom muab cov txiaj ntsig tau tseeb, cov khoom tau txais yuav tsum raug xa mus rau chav kuaj tam sim. Yog tias qhov no ua tsis tau, qhov kev kuaj ntshav yuav tsum tau kho nrog 10% formalin tov lossis 70% ethanol. Yog tias koj xav tau kev tshawb fawb txog pathomorphological, ces smears rau cytology yuav tsum tau ua ua ntej kho cov khoom.
Tus kws kho mob uas ua qhov kev tshawb fawb ua ntej muab cov lus piav qhia macroscopic ntawm cov khoom (qhia nws qhov loj, xim thiab sib xws), thiab tom qab ntawd siv cov txheej txheem tsim nyog los ua.kev npaj histological. Tom qab ntawd, nws kuaj pom cov kev hloov pauv hauv microscopic, ua qhov kev soj ntsuam thiab kev soj ntsuam anatomical thiab kos cov lus xaus.
Yuav siv li cas hauv cov txheej txheem kuaj histological?
Lawv feem ntau siv los kuaj xyuas cov hlwb txawv txav thiab paub meej tias mob qog noj ntshav. Yog li, kev soj ntsuam histological ntawm lub ncauj tsev menyuam ua rau nws tuaj yeem kuaj pom cov qog qog nqaij hlav hauv yuav luag 95% ntawm cov neeg mob.
Kev tshuaj xyuas ntawm cov tshuaj histological kuj tseem siv rau hauv kev tshawb fawb ntawm moles, polyps ntawm lub plab, ntau yam khoom siv biomaterials. Kev kuaj mob ntawm tus me nyuam hauv plab kuj tseem siv tau, uas tau sau tseg rau kev xav tias muaj kab mob tshwm sim.
