Daim ntawv thov ntawm Fluorescein Powder

Fluorescein hmoov, yog cov xim fluorescent uas emits lub ci ntsuab ci thaum raug ultraviolet lossis xiav lub teeb. Cov tshuaj lom neeg no feem ntau yog siv rau hauv ntau daim ntawv thov suav nrog kev tshuaj xyuas biomedical, microscopy, thiab txawm nyob rau hauv kev lag luam khoom noj.

Ib qho ntawm cov ntawv thov tseem ceeb ntawm nws yog nyob rau hauv kev kho mob uas nws yog siv los pom cov ntshav ntws thiab kuaj xyuas qee yam kab mob. Intravenous txhaj tshuaj fluorescein hmoov ua raws li los ntawm kev siv cov cuab yeej tshwj xeeb tso cai rau cov kws kho mob taug qab cov ntshav ntws thiab pinpoint blockages lossis lwm yam txawv txav. Tsis tas li ntawd, nws tseem tuaj yeem siv los kuaj xyuas qhov muag xws li pob txha puas lossis qhov tsis xws luag hauv cov hlab ntsha ntawm retina.

Feem ntau additive nyob rau hauv cov zaub mov kev lag luam uas nws yog siv los ua zaub mov coloring. Vim nws cov xim ntsuab ci, nws feem ntau siv hauv cov khoom qab zib, dej qab zib, thiab lwm yam khoom noj. Txawm li cas los xij, cov kev cai nruj yog nyob rau hauv qhov chaw kom ntseeg tau tias fluorescein hmoov yog siv nyob rau hauv qhov muaj kev nyab xeeb thiab tsis muaj teeb meem rau tib neeg noj qab haus huv.

Hauv microscopy, nws yog siv los sau cov molecules tshwj xeeb lossis cov qauv hauv cov hlwb lossis cov ntaub so ntswg. Qhov no tso cai rau cov kws tshawb fawb los soj ntsuam tus cwj pwm thiab kev sib cuam tshuam ntawm cov qauv no hauv lub sijhawm tiag tiag. Nws kuj tseem siv ntau hauv kev tshuaj ntsuam xyuas immunofluorescence txhawm rau kuaj pom muaj cov tshuaj tiv thaiv kab mob lossis cov tshuaj tiv thaiv.

Txawm hais tias nws muaj ntau daim ntawv thov, nws yuav tsum tau ua tib zoo saib xyuas vim tias nws tuaj yeem muaj tshuaj lom yog tias noj los yog nqus tau ntau heev. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav thiab khaws cia kom deb ntawm cov menyuam yaus.
