Histological tlhlahlobo: Seo e se ke

Histological hlahloba thuto morphological ea lisele le ho makala. Ho akarelletsa ho biopsy le hlahlobo ya lintho tse bonahalang a fumana ka nako ya ho buoa.

Thutong ena e etsoa ka morero oa ho hlahloba lefu le phekolo. Ke mokhoa o itseng oa bohlokoa oa bonoa ke kankere, hammoho le tsela eo ho fumana hore na ho atleha ha kalafo ya.

Ho tlhlahlobo histological, etsa lintho tse bonahalang terata le lokisetsa e ka tsela e itseng ho ithuta. Ka mor'a moo, sebetsa sa microscopy phethahetseng, hammoho le e ya boleng le ditirisanommogo tsa tekolo tse ba litšoantšo ba ile ba fumana.

The ntho e ka sehloohong ea tshekatsheka le ke litokisetso histological ne ba itokiselitse ho tloha mehaho e tsitsitseng. Tsena li akarelletsa swabs, menwana tswa lisele tsa filimi, hammoho le dilae mosesaane.

Bakeng sa proizvodnje litokisetso histological nka boitsebiso bo hlokahalang, e lokisa di-compacts dilae le hlahlelletse qaphalletsoa bona kapa boitshwaro opacification. mekhahlelo tsena ke lithethefatsi tse ithutile ke elektrone microscopy. Haeba tlhahlobo ea histological etsoa orthoscope leseli, le dikarolo sephetho le eona e lokela ho kenyeleditsweng ka setlhare kapa tse ling tse mahareng e bonaletsang.

Ho rarolla lithethefatsi tsena li ka sebelisa fapaneng mefuta microscopes: khanya, phetiso, anthivaerase, elektronike, mahlaseli le fluorescent le mohato lehlakoreng le leng. Ea bobeli e dumella ho nahana ka litšoantšo fapaneng lintho bonaletsang tse ke keng tsa bonoa ke microscopy tloaelehileng.

Re lokela ho hlokomela hore ha ho ithuta histological bontša, terata tse bonahalang ho ka feta tlas'a taolo bonwang (tabeng ea letlalo kapa bonahalang mucosa biopsies) le kenngwa tshebetsong ke mekhoa e khethehileng (biopsy hare). Kahoo, ka lithuto tsa dinama tse nyenyane tse ka tlōla ka ho ba le puncture nale aspirates, lesapo craniotomy.

Ho na le khopolo ea biopsy targeted, moo dinama tse nyenyane tse ho itlhahloba ba isoa tlas'a taolo bonwang le ho sebelisa ha khethehileng disebediswsa Optical kapa ka ho sebelisa ultrasound maemong a.

Ke habohlokoa ho hlokomela hore e le hore ho ba ngotse hlahlobo histological o ile a fana ka lebaka le 'nete, le lintho tse bonahalang a fumana lokela ho ho nkoa ka hang-hang ho laboratoring. Hlōleha eo, biopsy ke ho hlokahala hore ho rarolla 10% tharollo wa formalin kapa 70% ethyl joala. Ha o batla ho phetha ka poso ya setopo itlhahloba, pele ho lokisa sepeiti lintho tse bonahalang lokela ho etsa smears bakeng cytology.

The pathologist ba khanna ho etsa lipatlisiso pele e fana ka macroscopic tse bonahalang tlhaloso (bontšang boholo ba eona, 'mala le tumellano),' me ka ho eketsehileng e sebetsa le mekhoa e ama proizvodnje litokisetso histological. Ka mor'a moo, o ile a sibolla liphetoho tse nyenyane, ho khanna ea tleleniki le anatomical and analysis, ho etsa liqeto.

Maemong a mang, mekhoa histological tlhlahlobo sebelisoa?

Hangata ka ho fetisisa ba li sebelisetsoa ho hlokomela lisele tse sa tloaelehang le netefatso ya kankere. Ho joalo, sobotta ea popelo e ka khona ho utloa hlahala thulaganyou e hoo e batlang e 95% ea linyeoe.

Ho hlahloba litokisetso histological ba boetse le sebelisoa ka lithuto tsa moles, polyps la mala, ho tse fapa-fapaneng biomaterial. E ka boela ho sebediswa histological hlahloba lesea le, e leng e ba laela hore belaela lefa malwetse.
