Mannitol, nrog rau cov tshuaj formula C6H14O6, yog qab zib cawv uas yog ib qho isomer ntawm sorbitol. Nws yog soluble nyob rau hauv dej thiab yog dawb crystalline hmoov nrog ib tug qab zib saj zoo li sucrose. Nws yog ib qho dej cawv ua haujlwm nrog kev ua haujlwm zoo. Siv dav hauv kev lag luam xws li tshuaj, khoom noj, thiab tshuaj.
Nws yog dav siv nyob rau hauv ntau lub teb xws li cov hauv qab no:
Mannitol hmoov yog ib yam khoom siv dav siv hauv ntau yam xws li zaub mov, kev lag luam, thiab tshuaj. cov
Hais txog cov khoom noj, cov hmoov mannitol feem ntau yog siv los ua cov hmoov nplaum nplaum thiab cov khoom qab zib, thiab siv rau hauv cov khoom noj xws li zom cov pos hniav, maltose, thiab mov ncuav. Nws muaj qhov nqus dej tsawg, qab zib thiab qab ntxiag saj, thiab tsim nyog ua zaub mov ntxiv. Nws kuj tseem siv tau los ua zaub mov rau cov neeg mob ntshav qab zib, cov zaub mov tsim lub cev thiab lwm yam tsis muaj calorie tsawg, cov qab zib qab zib tsawg.
Hauv kev lag luam, mannitol hmoov tuaj yeem siv los ua tus neeg sawv cev rau kev tsim cov polymannitol propylene oxide ether, uas muaj roj tsis kam thiab kub oxidation tsis kam thiab yog dav siv hauv kev lag luam yas. Tsis tas li ntawd, mannitol hmoov kuj tseem siv los ua cov khoom tawg, detonators, thiab lwm yam.
Ib qho ntawm cov ntawv thov tseem ceeb ntawm mannitol hmoov yog nyob rau hauv kev kho mob. Raws li ib qho osmotic diuretic, mannitol hmoov nce plasma osmotic siab, txhawb cov nqaij mos lub cev qhuav dej, thiab yog li txo intracranial siab thiab intraocular siab. Nws yog feem ntau siv los kho cov kab mob xws li cerebral edema thiab glaucoma, thiab muaj kev puas tsuaj tsawg rau lub raum, ua rau nws tsim nyog rau kev kho mob ntawm tus mob tubular necrosis thiab lwm yam mob. Tsis tas li ntawd, mannitol hmoov kuj tuaj yeem siv los tiv thaiv lub raum tsis ua haujlwm thiab kho cem quav.

Feature ntawmMannitol hmoov:
- Mannitol hmoov muaj ntau yam ntxwv. Ua ntej, nws yog polyol lossis qab zib cawv uas yog isomer ntawm sorbitol. Nws tsis yog hygroscopic, odorless, thiab muaj ib tug txias qab zib saj, nrog ib tug qab zib theem ntawm 0 55-0.65 npaug ntawm sucrose. Mannitol absorbs cua sov thaum yaj hauv dej, thiab feem ntau ntawm nws tsis hloov hauv lub cev, tab sis tawm los ntawm cov zis.
- Mannitol hmoov muaj ntau yam kev siv hauv ntau qhov chaw. Nws tuaj yeem tsis tsuas yog siv los ua cov khoom qab zib thiab khoom noj khoom haus ntxiv, tab sis kuj tseem nyob rau hauv kev lag luam tshuaj, xws li txo qis intracranial siab, intraocular siab, thiab ntshav siab, tiv thaiv thiab kho lub hlwb edema, glaucoma, mob raum tsis ua hauj lwm, thiab lwm yam. mannitol kuj tseem siv rau hauv kev tshawb fawb txog lub neej, kev lag luam zaub mov, thiab kev lag luam tshuaj.
- Mannitol hmoov tsis nqus dej noo nyob rau hauv qhov chaw ntub dej, uas ua rau nws muaj txiaj ntsig hauv qee cov khoom noj thiab tshuaj.
