Mu XNUMX, Proust adazipatula koyamba ku mtengo wa mana, pomwe mannitol adapeza dzina lake. YTBIO D-Mannitol ndi polyol yokhala ndi kaboni isanu ndi umodzi, ufa woyera wa crystal, wokhala ndi mamolekyu a C6H14O6 ndi kulemera kwa 182.17. Mannitol imapezeka kwambiri mu algae, zipatso, masamba a zomera ndi zomera, ndipo imapezekanso pang'ono pafupifupi masamba onse.

D-mannitol ufa idagwiritsidwa ntchito ngati zotsekemera komanso zotsekemera, koma pambuyo pake zidadziwika kuti imakhalanso ndi diuretic ndi dehydrating ndipo idagwiritsidwa ntchito m'munda wamankhwala. The pharmacological zotsatira za mannitol makamaka ndi kuwonjezeka plasma osmotic kuthamanga, kusamutsa madzi kuchokera minofu yamadzimadzi m'madzi a m'magazi, potero kumawonjezera kusefera kwa glomerular ndi mkodzo linanena bungwe, excreting electrolytes monga sodium ndi potaziyamu, potero kuchepetsa edema minofu.

Pakalipano, njira yomwe imagwiritsidwa ntchito kwambiri popanga mafakitale a ufa wa D-mannitol ndi kaphatikizidwe ka mankhwala. Amagwiritsa ntchito fructose / shuga wosakaniza ngati gawo lapansi, ndipo amapeza mannitol kupyolera mu nickel-catalyzed hydrogenation ya fructose / shuga osakaniza pansi pa kutentha ndi kuthamanga kwambiri.

YTBIO imapereka 99% D mannitol ufa wambiri, wokhala ndi chiyero chambiri, zinthu zokhazikika komanso ufa wabwino. YTBIO yadutsa Halal, Kosher, FDA, ISO ndi ziphaso zina. Tili ndi gulu labwino kwambiri la R&D, gulu lodziwa kupanga, komanso gulu la akatswiri ogulitsa. Titha kusintha makonda osiyanasiyana amtundu wamba komanso zofananira. Titha kupereka malipoti ovomerezeka a chipani chachitatu.

ubwino:

Kuthamanga kwambiri

Mannitol pa minofu ya ocular, pokhalabe ndi kusiyana kwakukulu kwa plasma-atrial fluid osmotic pressure, kumapangitsa kusintha kwamadzimadzi mu mitsempha. Panthawi imodzimodziyo, thupi la vitreous limatulutsa madzi ndi kuchepa mphamvu. Zotsatira zake ndikuchepetsa munthawi yomweyo kuthamanga kwa intravitreal, kuthamanga kwa intraocular, komanso kupanikizika kwa intraorbital, zomwe zikuwonetsa mphamvu yamphamvu ya hypotensive.

Wodzikongoletsa

Mphamvu ya diuretic D Mannitol ufa zimathandizanso ku zotsatira zomwe zili pamwambazi. Mothandizidwa ndi mannitol, mkodzo wochuluka wa hypotonic ukhoza kutulutsidwa, plasma imakhazikika kwambiri, ndipo kusiyana kwa kuthamanga kwa osmotic kumawonjezeka, motero kumawonjezera mphamvu ya antihypertensive ya mannitol.

Anti-kutupa, Kutonthoza

D Mannitol Powder imatha kuthandizira kutonthoza khungu pochepetsa zotupa zapakhungu, zofiira, komanso kuyabwa. Amagwiritsidwanso ntchito kuti achepetse kusapeza bwino komwe kumachitika chifukwa cha ziwengo kapena zovuta zapakhungu.

Moisturizing ndi Zakudya

Chifukwa mannitol imakhala ndi magulu ambiri a hydroxyl, imatha kuphatikizidwa ndi madzi mu mawonekedwe a hydrogen bonding, moisturizing effect, kotero nthawi zambiri imawonjezeredwa kuzinthu zina zosamalira khungu.

Kulambala

Peroxynitrite anion ndi kuphatikiza kwa superoxide radicals ndi nitroso ions, komanso wamba wamba waulere m'thupi, izi zaulere zimagwirizanitsidwa ndi mtundu wa pigmentation. D Mannitol ufa imathandizira kuwongolera khungu komanso K kutsika, zowawa zapakhungu zimakhalanso ndi zoletsa zina.

Kodi ntchito zamsika za D-Mannitol ndi ziti?

Mu zodzoladzola:

D Mannitol ufa mu zodzoladzola, ndi mankhwala chisamaliro khungu, udindo waukulu wa zomatira, ndi wothandizila moisturizing. Chiwopsezo cha 1, chotetezeka, chingagwiritsidwe ntchito molimba mtima, kwa amayi apakati nthawi zambiri alibe mphamvu, ndipo D mannitol sizimayambitsa ziphuphu. Peroxynitrite anion ndi kuphatikiza kwa superoxide radicals ndi nitroso ions komanso ndi wamba wamba waulere mu vivo, ma free radicals awa ndi ma pigmentation okhudzana ndi kuchotsedwa kwa Mannitol amathandizira kuwongolera khungu komanso odana ndi ukalamba, ziwengo zapakhungu zimakhalanso ndi digiri inayake. kuletsa. D Mannitol ufa ukhoza kulepheretsa kuwonongeka kwa khungu ndi kukalamba kwa chithunzi ndipo kumakhala ndi ntchito yonyowa.

Monga Wothandizira Mankhwala:

Choncho, amagwiritsidwa ntchito kwambiri popanga mapiritsi otafuna monga mapiritsi ochepetsetsa, oral cooling agents, ndi nitroglycerin. Mawonekedwe ake a granular amagwiritsidwa ntchito makamaka ngati chothandizira pakuponderezana kwa piritsi mwachindunji.

M'munda wa Chakudya:

Mannitol amadziwika padziko lonse lapansi kuti ndi otetezeka kugwiritsidwa ntchito pazakudya.

Mwachitsanzo, mu mankhwala abwino, mannitol angagwiritsidwe ntchito popanga ma polyethers, omwe amagwiritsidwa ntchito popanga thovu lopanda kutentha kwambiri kuti likhale lotetezera kutentha ndi kuteteza moto. Foam ya Mannitol polyether ndi yabwino kwambiri ndipo imatha kupirira kutentha mpaka 180 ° C, zomwe sizingafanane ndi thovu la polyether lopangidwa ndi ma polyols ena, ndipo lingagwiritsidwe ntchito popaka mapaipi apadera.
