Drabkin's Reagent yog siv rau qhov muaj nuj nqis, txiav txim xim xim ntawm hemoglobin concentration hauv cov ntshav ntawm 540 nm. Drabkin tus Kev daws teeb meem cuam tshuam nrog txhua yam ntawm hemoglobin tshwj tsis yog sulfhemoglobin, cov xim uas ib txwm tshwm sim hauv ib feeb nkaus xwb hauv cov ntshav.
Ntawm no, koj ua li cas Drabkin txoj kev daws teeb meem?
Rau npaj cov Drabkin Kev daws , rov tsim dua ib lub vial ntawm Drabkin lub Reagent nrog 1000 ml dej. Tom qab ntawd ntxiv 0.5 ml ntawm 30% Brij 35 Tshuaj , Khoom Cai B 4184, rau 1000 ml ntawm kev rov tsim dua Drabkin lub Reagent . Sib tov kom zoo thiab lim yog tias cov khoom tsis haum.
Cyanmethemoglobin txoj kev yog dab tsi? Hauv Drabkin's txoj kev ntawm hemoglobin kwv yees hemoglobin yog oxidized rau methemoglobin los ntawm cov poov tshuaj ferricyanide, uas cuam tshuam nrog cyanide ions ntawm potassium cyanide los tsim cyanmethemoglobin . Cov hemoglobin tau kwv yees nrog kev pab ntawm cyanmethemoglobin nkhaus.
Zoo ib yam tuaj yeem nug, dab tsi yog qhov muaj pes tsawg leeg ntawm Drabkin cov tshuaj reagent?
Drabkin yog reagent yog siv hauv kev ntsuas hemoglobin los ntawm kev kuaj ntshav. Nws suav nrog potassium ferricyanide, potassium cyanide thiab potassium dihydrogen phosphate ua cov khoom. Potassium ferricyanide oxidizes hemoglobin rau methemoglobin thiab tom qab ntawd mus rau cyanmethemoglobin.
Lub hauv paus ntsiab lus tseem ceeb ntawm Cyanmethemoglobin txiav txim siab ntawm hemoglobin yog dab tsi?
Cyanmethemoglobin Txoj Kev txoj cai ntawm txoj kev no nyob hauv kev hloov pauv ntawm hemoglobin cov rau cyanmethemoglobin los ntawm kev ntxiv Potassium cyanide thiab ferricyanide uas nws qhov kev nqus tau ntsuas ntawm 540 nm hauv lub tshuab ntsuas hluav taws xob ntsuas hluav taws xob tiv thaiv cov txheej txheem daws teeb meem.

Cov ntsiav tshuaj daim ntawv twg muaj cov txheej tshwj xeeb uas tiv thaiv lub plab acid thiab ua rau cov tshuaj yaj hauv cov hnyuv?
Cov txheej txheej enteric yog cov txheej txheem polymer siv rau ntawm cov tshuaj hauv qhov ncauj uas tiv thaiv nws txoj kev tawg lossis tsis tawg hauv ib puag ncig lub plab
Dab tsi yog qhov muaj pes tsawg leeg ntawm Drabkin's reagent?
Drabkin's reagent yog siv los ntsuas hemoglobin los ntawm cov ntshav kuaj. Nws suav nrog potassium ferricyanide, potassium cyanide thiab potassium dihydrogen phosphate ua cov khoom. Potassium ferricyanide oxidizes hemoglobin rau methemoglobin thiab tom qab ntawd mus rau cyanmethemoglobin
Thaum sib xyaw cov tshuaj insulin luv luv thiab cov tshuaj insulin nruab nrab hauv tib lub koob txhaj tshuaj insulin yuav tsum tau kos ua ntej?
Thaum koj sib xyaw cov tshuaj insulin tsis tu ncua nrog lwm hom insulin, ib txwm kos cov insulin tsis tu ncua rau hauv rab koob ua ntej. Thaum koj sib xyaw ob hom tshuaj insulin uas tsis yog cov tshuaj insulin ib txwm, nws tsis muaj teeb meem dab tsi xaj koj coj lawv mus rau hauv lub raj mis
Cov tshuaj tiv thaiv ua haujlwm li cas lawv ua haujlwm tiv thaiv kab mob thiab kab mob?
Cov tshuaj tiv thaiv ua haujlwm los ntawm kev cob qhia lub cev tiv thaiv kab mob kom paub thiab tawm tsam cov kab mob, xws li kab mob lossis kab mob. Txhawm rau ua qhov no, qee cov molecules los ntawm cov kab mob yuav tsum tau nkag rau hauv lub cev kom ua rau muaj kev tiv thaiv kab mob. Cov molecules no hu ua antigens, thiab lawv muaj nyob rau tag nrho cov kab mob thiab cov kab mob
Dab tsi yog qhov sib txawv ntawm cov tshuaj yuav tshuaj thiab cov lus nug ntawm cov tshuaj hauv khw muag tshuaj?
Cov tshuaj yuav yog cov tshuaj uas xav kom kws kho mob sau tseg kom muab faib tawm. Hauv lub txee, cov tshuaj yog cov tshuaj zoo li Advil lossis Tylenol uas koj tsis xav tau kws kho mob sau tseg los yuav. Qhov sib txawv tseem ceeb ntawm ob yog tias koj yuav tsum muaj daim ntawv yuav tshuaj tshuaj yog tias nws yog tshuaj yuav tshuaj
