Kev kho mob thiab kev kho mob siv Pure DMSO
Dimethyl sulfoxide yog ib qho purified npaj siv nyob rau hauv cov tshuaj los txo cov tsos mob ntawm interstitial cystitis, mob zais zis mob. Cov txheej txheem yog ua los ntawm ib tug kws kho mob:
Lub catheter lossis syringe yog siv los tso cov tshuaj DMSO rau hauv lub zais zis.
Cov tshuaj tso cai nyob twj ywm hauv lub zais zis rau li 15 feeb.
Tom qab ntawd tus neeg mob tshem tawm cov tshuaj los ntawm kev tso zis.
Tsis tas li ntawd, DMSO yog siv nyob rau hauv cov tshuaj pleev ib ce tshuaj raws li ib tug nkag mus rau hauv lub enhancer, pab cov khoom xyaw nquag mus txog tob txheej ntawm daim tawv nqaij. Nws daim ntawv thov kev kho mob yuav raug tso cai raws li txoj cai thiab yuav tsum tau ua raws li kev saib xyuas kev tshaj lij.
Laboratory thiab Industrial Applications
Tshaj li kev siv tshuaj kho mob, DMSO ntshiab yog siv dav hauv cov chaw sim thiab kev lag luam:

Cov ntawv thov dav dav no qhia txog qhov tshwj xeeb kev daws teeb meem ntawm DMSO ntshiab.
Kev txiav txim siab zoo thiab tuav
Thaum xaiv thiab tuav DMSO ntshiab, cov ntsiab lus hauv qab no tseem ceeb:
Qib purity: siab - qib purity xws li 99.9% yog qhov nyiam rau kev siv tshuaj, tshuaj xyuas thiab hluav taws xob; txheeb xyuas cov ntsiab lus dej, uas yuav tsum tsis tshua muaj vim DMSO yog hygroscopic.
Cia: khaws cov thawv ntim kom nruj rau hauv qhov chaw txias, qhuav kom tsis txhob nqus dej noo.
Kev nkag mus ntawm daim tawv nqaij: DMSO nkag mus rau ntawm daim tawv nqaij thiab tuaj yeem nqa cov tshuaj yaj mus rau hauv lub cev; hnav hnab looj tes tiv thaiv thiab tiv thaiv khaub ncaws.
Compatibility: zam kev sib xyaw DMSO nrog cov muaj zog oxidizing lossis txo cov neeg ua haujlwm yam tsis muaj kev tshuaj xyuas zoo.
Kev siv kho mob: txhua yam kev siv kho mob ntawm DMSO yuav tsum ua raws li cov txheej txheem pom zoo thiab cov lus qhia kev kho mob.
Nrog rau kev xaiv qib thiab kev tuav tswj kom raug, DMSO ntshiab yog qhov muaj txiaj ntsig zoo thiab muaj txiaj ntsig thoob plaws ntau thaj chaw.
Cov lus nug nquag
DMSO ntshiab siv rau dab tsi?
Ntshiab DMSO yog siv los ua cov kuab tshuaj ntau yam hauv cov chaw kuaj mob thiab kev lag luam, raws li kev nkag mus rau hauv cov tshuaj pleev tshuaj, thiab ua rau lub zais zis rau kev cuam tshuam cov tsos mob ntawm tus mob cystitis nyob rau hauv kev saib xyuas kev kho mob.
Puas yog DMSO muaj kev nyab xeeb?
