HPMC rau Tshuaj Ntxuav Tes

Kev ntxuav teser yog ib yam khoom siv tshuaj lom neeg uas siv niaj hnub. Vim muaj tus kab mob COVID-19 kis thoob plaws, nws tau nrov heev rau cov pej xeem.Hydroxypropyl methylcellulose HPMC, ib qho khoom siv tseem ceeb hauv kev ntxuav cov gel, kuj tseem nyiam los ntawm cov chaw tsim khoom siv biochemical reagent.

Hydroxypropyl methylcellulose HPMCsiv rau hauv cov tshuaj ntxuav tes vim nws cov tuab, viscosity thiab permeability. Cov neeg feem coob nyiam cov gels dua li cov tshuaj ntxuav tes.Hydroxypropyl methylcellulose HPMCtuaj yeem hloov cov tshuaj mus ua cov gels thiab cov gels ruaj khov dua thiab yooj yim siv dua li cov kua. Qhov kev sib xyaw ua ke ntawmHydroxypropyl methylcellulose HPMCkuj yog qhov tseeb nyob rau hauv qhov ntau ntawm 0.2% -0.5%.Hydroxypropyl methylcellulose HPMCtuaj yeem ua rau cov kua dej muaj cov txiaj ntsig tshwj xeeb thiab cov khoom rheological. Tsuas yog qhov concentration qis heev tuaj yeem ua rau qee cov khoom ntxiv uas tsis yaj (cov khoom me me, cov roj poob, thiab lwm yam) kom ua tiav cov dej noo tas mus li.

Vim nws muaj zog heev uas nws tuaj yeem ua rau lub suspension puas tsuajHydroxypropyl methylcellulose HPMCyog siv dav. Tsis tas li ntawd,Hydroxypropyl methylcellulose HPMCsiv rau hauv cov tshuaj ntxuav tes gel tuaj yeem ua tiav qhov zoo pob tshab. Tom qab neutralization thiab ionization ntawm carboxyl pawg, vim yog kev sib koom ua ke ntawm cov nqi tsis zoo, cov saw hlau molecular tau tawg thiab nthuav dav, qhia txog kev nthuav dav thiab viscosity zoo. Cov yam ntxwv zoo li no ua rauHydroxypropyl methylcellulose HPMCua ib qho ntawm cov khoom siv tseem ceeb rau kev ntxuav tes.

Qhov tseem ceeb tshaj plaws ntawm kev siv cov tshuaj ntxuav tes uas tsis tas siv tes yog tias nws zam kev ntxuav ntau zaus thiab tsis tuaj yeem ntxuav nrog dej, tab sis kuj tuaj yeem ua tiav kev tiv thaiv thiab tshem tawm cov kab mob tes. Tshwj xeeb tshaj yog thaum lub caij ntuj sov, kev loj hlob ntawm cov kab mob nce ntxiv, tshwj xeeb tshaj yog cov kab mob hauv plab hnyuv, pyogenic cocci, poov xab thiab lwm yam kab mob. Cov khoom xyaw tseem ceeb ntawm cov tshuaj tua kab mob hauv cov tshuaj ntxuav tes yog ethanol, lwm cov tshuaj tua kab mob muaj yog tias lawv ua haujlwm tau zoo, thiab qee qhov yog guanidine. Cov ntsiab lus ntawm cov neeg sawv cev bacteriostatic yog ob peb puas feem pua, feem ntau yog 23%, thiab cov ntsiab lus ntawm txhua yam tshuaj bacteriostatic kuj muaj cov kev cai meej hauv lub tebchaws tus qauv.

Raws li tus kab mob tshiab kis mus rau hauv tsev thiab txawv teb chaws, cov khoom siv tua kab mob tsis txaus siv sijhawm luv luv, tshwj xeeb tshaj yog thaum tawm mus tua kab mob ntawm cov kua ntxuav tes uas tsis muaj dab tsi, yog qhov vwm heev uas yuav nyiag,Hydroxypropyl methylcellulose HPMC ua ib qho ntawm cov khoom xyaw ntawm cov xab npum ua kua tsis muaj, ntau tus neeg tsim khoom rau qhov nce nqi, ib feem ntawm tus neeg tsim khoom vim tias muaj ntau qhov kev txiav txim tsis tuaj yeem muab khoom ib txwm muaj, Txawm li cas los xij, Ua ib qho ntawm cov chaw tsim khoom ntawmHydroxypropyl methylcellulose HPMC cov khoom,Anxin cellulose tsis tuaj yeem tsuas yog lav qhov khoom siv ib txwm muaj, tab sis kuj tswj tus nqi tsis nce, uas yog qhov chaw tsim khoom tiag tiag ntawm lub siab.
