Makhalidwe oyambira a zinc oxide:
◆Kapangidwe ka thupi ndi mankhwala
Zinc oxide, monga oxide ya zinc, imakhala ndi mphamvu ya amphoteric alkaline. N'zovuta kusungunuka m'madzi, koma imatha kusungunuka mosavuta mu ma acid ndi maziko olimba. Kulemera kwake kwa molekyulu ndi 81.41 ndipo malo ake osungunuka ndi okwera kufika pa 1975 ℃. Pa kutentha kwa chipinda, zinc oxide nthawi zambiri imawoneka ngati makhiristo a hexagonal, opanda fungo komanso osakoma, ndipo imakhala ndi mphamvu yokhazikika. Pankhani ya chakudya, timagwiritsa ntchito kwambiri kuphatikizana kwake, kuyamwa, ndi mphamvu ya antibacterial. Kuiyika mu chakudya cha ana a nkhumba sikungowonjezera kukula kwawo, komanso kumateteza bwino mavuto awo otsegula m'mimba.

◆Njira ndi njira yogwirira ntchito
Mlingo wochuluka wa zinc oxide watsimikiziridwa kwambiri kuti umathandiza kuti ana a nkhumba akule bwino komanso kupewa kutsegula m'mimba. Mfundo ya ntchito yake imachokera makamaka ku momwe zinc oxide (ZnO) imagwirira ntchito m'thupi, osati m'mitundu ina ya zinc. Chogwiritsira ntchitochi chingathandize kwambiri kukula kwa ana a nkhumba ndikuchepetsa kwambiri kufalikira kwa matenda otsegula m'mimba. Zinc oxide imalimbikitsa kukula kwa ana a nkhumba komanso thanzi la m'mimba kudzera mu momwe ma molekyulu ake amakhalira ZnO. Mlingo wochuluka wa ZnO umalepheretsa ndikugwirizanitsa asidi wa m'mimba m'mimba ndi m'matumbo ang'onoang'ono, ndikuyamwa mabakiteriya owopsa, zomwe zimapangitsa kuti kukula kukhale bwino.

M'malo okhala ndi asidi m'mimba, zinc oxide imalowa m'thupi.Kuphatikizika kwa asidi ndi asidi m'mimba, ndipo yankho lake ndi: ZnO+2H+→ Zn ² ⁺+H ₂ O. Izi zikutanthauza kuti mole iliyonse ya zinc oxide imadya ma mole awiri a hydrogen ions. Ngati 2kg/t ya zinc oxide yokhazikika yawonjezedwa ku chakudya chophunzitsira ana a nkhumba, ndipo poganiza kuti ana a nkhumba olekanitsidwa ali ndi chakudya cha 200g tsiku lililonse, adzadya 0.4g ya zinc oxide patsiku, yomwe ndi ma mole 0.005 a zinc oxide. Mwanjira imeneyi, ma mole 0.01 a hydrogen ions adzadyedwa, zomwe zili pafupifupi ma milliliters 100 a asidi m'mimba ndi pH ya 1. Mwanjira ina, gawo ili la zinc oxide (pafupifupi 70-80%) lomwe limayanjanitsidwa ndi asidi m'mimba lidzadya ma milliliters 70-80 a pH 1 acid m'mimba, zomwe zimapangitsa pafupifupi 80% ya kutulutsa asidi m'mimba tsiku lililonse mwa ana a nkhumba olekanitsidwa. Kudya koteroko mosakayikira kudzakhudza kwambiri kugaya mapuloteni ndi michere ina m'zakudya.

Kuopsa kwa zinc oxide wambiri:
Pa nthawi yoyamwitsa ana a nkhumba, kuchuluka kwa zinc komwe kumafunikira ndi pafupifupi 100-120mg/kg. Komabe, kuchuluka kwa Zn ²+ kumatha kupikisana ndi zinthu zonyamula pamwamba pa maselo a mucosal am'mimba, motero kuletsa kuyamwa kwa zinthu zina monga mkuwa ndi chitsulo. Kuletsa kumeneku kumasokoneza kulinganiza kwa zinthu zina m'matumbo, zomwe zimapangitsa kuti zakudya zina zisayamwitse. Kafukufuku wasonyeza kuti kuchuluka kwa zinc oxide kumachepetsa kwambiri kuyamwa kwa zinthu zachitsulo m'matumbo, motero kumakhudza kapangidwe ndi kapangidwe ka hemoglobin. Nthawi yomweyo, zinc oxide wambiri ungayambitsenso kupanga kwambiri metallothionein, yomwe imamangirira kwambiri ku ayoni amkuwa, zomwe zimapangitsa kuti mkuwa ukhale wopanda mphamvu. Kuphatikiza apo, kuwonjezeka kwakukulu kwa zinc m'chiwindi ndi impso kungayambitsenso mavuto monga kuchepa kwa magazi m'thupi, khungu loyera, ndi tsitsi louma.

◆Zotsatira pa asidi m'mimba ndi kugaya mapuloteni
Zinc oxide, monga chinthu cha alkaline pang'ono, ili ndi asidi wa 1193.5, yachiwiri pambuyo pa ufa wa miyala (acidity value wa 1523.5), ndipo ili m'gulu la zinthu zopangira chakudya. Zinc oxide wambiri umadya asidi wambiri m'mimba, umalepheretsa kugaya mapuloteni, komanso umakhudza kugaya ndi kuyamwa kwa michere ina. Kudya koteroko mosakayikira kudzakhudza kwambiri kugaya mapuloteni ndi michere ina m'zakudya.

◆Zopinga zoyamwitsa zakudya zina
Zn²+ yochulukirapo imapikisana ndi kuyamwa kwa michere, zomwe zimakhudza kuyamwa kwa zinthu zochepa monga chitsulo ndi mkuwa, motero zimakhudza kapangidwe ka hemoglobin ndikuyambitsa mavuto azaumoyo monga kuchepa kwa magazi m'thupi.
◆Kuphulika kwa maselo a mucosal m'mimba
Kafukufuku wasonyeza kuti kuchuluka kwambiri kwa Zn²+ m'maselo a mucosal m'matumbo kungayambitse apoptosis ya maselo ndikusokoneza mkhalidwe wokhazikika wa maselo am'mimba. Izi sizimangokhudza ntchito yachibadwa ya ma enzyme okhala ndi zinc ndi zinthu zina zolembera, komanso zimawonjezera kufa kwa maselo, zomwe zimapangitsa kuti matenda a m'matumbo akhale ndi mavuto.

◆Zotsatira za ayoni a zinki pa chilengedwe
Ma ayoni a zinki omwe sangalowe m'matumbo mokwanira pamapeto pake amatulutsidwa pamodzi ndi ndowe. Izi zimapangitsa kuti kuchuluka kwa zinki m'ndowe kuchuluke kwambiri, zomwe zimapangitsa kuti kuchuluka kwa zinki kosalowa m'madzi kutuluke, zomwe zimayambitsa kuipitsidwa kwa chilengedwe. Kuchuluka kwa zinki m'madzi sikungoyambitsa kuipitsidwa kwa nthaka kokha, komanso kungayambitse mavuto azachilengedwe monga kuipitsidwa kwa zitsulo zolemera m'madzi apansi panthaka.

Ubwino wa zinc oxide ndi zinthu zomwe zimateteza:
◆Zotsatira zabwino za zinc oxide yoteteza
Kupanga zinthu zoteteza zinc oxide cholinga chake ndi kugwiritsa ntchito mokwanira mphamvu yoletsa kutsegula m'mimba ya zinc oxide. Kudzera mu njira zapadera zoteteza, zinc oxide yambiri imatha kufika m'matumbo, motero imagwiritsa ntchito mphamvu yake yoletsa kutsegula m'mimba ndikukweza kugwiritsa ntchito bwino kwa zinc oxide. Njira yochepetsera mlingo wochepa iyi ingathandize kukwaniritsa mphamvu yoletsa kutsegula m'mimba ya zinc oxide yambiri. Kuphatikiza apo, njirayi ingachepetsenso momwe zinc oxide imagwirira ntchito ndi asidi m'mimba, kuchepetsa kudya kwa H+, kupewa kupanga kwambiri Zn ²+, potero kukweza chimbudzi ndi kugwiritsa ntchito mapuloteni, kulimbikitsa kukula kwa ana a nkhumba, ndikukweza ubweya wawo. Kuyesa kwina kwa nyama kwatsimikizira kuti zinc oxide yoteteza imatha kuchepetsa kudya asidi m'mimba mwa ana a nkhumba, kusintha chimbudzi cha zakudya monga zinthu zouma, nayitrogeni, mphamvu, ndi zina zotero, ndikuwonjezera kwambiri kulemera kwa tsiku ndi tsiku komanso chiŵerengero cha nyama ndi chakudya cha ana a nkhumba.

◆Mtengo wa mankhwala ndi ubwino wa zinc oxide:
Kumathandiza kuti chakudya chigayidwe bwino komanso kuti chigwiritsidwe ntchito bwino, zomwe zimathandiza kuti chakudya chizigwira bwino ntchito; Nthawi yomweyo, zimathandiza kuchepetsa kufalikira kwa matenda otsegula m'mimba komanso kuteteza thanzi la m'mimba.
Kuti ana a nkhumba azitha kukula bwino pambuyo pake, mankhwalawa amatha kusintha kwambiri kukula kwawo ndikuthetsa mavuto monga khungu lotuwa ndi tsitsi louma.
Kapangidwe kake kowonjezera pang'ono sikuti kamangochepetsa chiopsezo cha zinc yambiri, komanso kumachepetsa kuipitsidwa komwe kungachitike chifukwa cha kutulutsa zinc yambiri ku chilengedwe.
