Amakuru - Gukoresha Oxyde Isanzwe ya Zinc mu kurwanya impiswi z'abana b'ingurube

Oxyde ya zinki, izwi cyane nka zinc white, ni amphotericokiside ya zinkiNtishobora gushonga mu mazi ariko ishonga muri aside na alkali ikomeye. Formula yayo ya shimi ni ZnO, uburemere bwa molekile ni 81.37, umubare wa CAS ni 1314-13-2, aho gushonga ni 1975℃ (kubora), aho kubira ni 2360℃, kandi ntishobora gushonga mu mazi. Ikoreshwa cyane mu bintu birenga 20 nko muri pulasitiki, ibintu bya silicate, rabu y'ubukorano, amavuta, amarangi n'ibindi bisigazwa, amavuta yo kwisiga, kole, ibiryo, bateri, ibigabanya umuriro,n'ibindi.

III. Imbogamizi zo gucibwamo kw'ingurube mu bana bato n'akamaro k'ubuvuziokiside ya zinki

Guhekenya umwana ni ikintu gikomeye gihangayikishije mu buzima bw'umwana w'ingurube. Ibibazo nk'imikorere idahwitse y'amara, imisemburo idahagije yo mu igogora, no kudahuza kw'ibimera akenshi bitera impiswi nyuma yo kuhekenya umwana (PWD), ibi bikaba bibangamira cyane imikorere y'ingurube n'inyungu zo kororoka. Kubera ko bisanzwe, ingurube zisanzwe zihura n'ibibazo nk'ibi:okiside ya zinkibyagaragaye ko bifite ingaruka zikomeye ku kurwanya impiswi mu myaka ya 1980, byabaye "igipimo ngenderwaho cya zahabu" ku nganda z'amatungo ku isi mu guhangana n'abafite ubumuga. Ubushakashatsi bwagaragaje ko kongeramo 2500-3000 mg/kgokiside ya zinkiishobora kugabanya igipimo cy'impiswi ku kigero cya 40%-60%, mu gihe yongera ibiro ku kigero cya 10%-15%. Akamaro kayo k'ingenzi ni ugutuma amara ahora neza vuba binyuze mu buryo butandukanye, bigatanga uburinzi bw'ingenzi ku ngurube.

Imbogamizi zo gucibwamo mu ngurube zokejwe n'akamaro ka zinc oxide mu buvuzi

IV.Uburyo bw'imikorere yaokiside ya zinkikurwanya impiswi

1)Gukomeza uruzitiro rw'amara

Oxyde ya zinkiBitera imbaraga mu kwiyongera kw'uturemangingo tw'inda, byongera cyane uburebure bw'inkondo y'umura ugana ku burebure bwa crypt, byongera ubuso bwo kwinjiza intungamubiri, kandi bikongera uburyo poroteyine zifatanye mu buryo buhamye (Occludin, ZO-1), bigabanya kwinjira mu mara, kandi bibuza kwibasira indwara ziterwa n'udukoko. Birinda imikorere y'uruvange rw'inkondo y'umura, byongera ubushobozi bwo kurwanya udukoko tw'ingurube, kandi bigabanya impiswi.

2)Kugenzura uburinganire bw'udukoko two mu mara

Oxyde ya zinkiikora hydrogen peroxide free radicals mu mara, ikaba ari ikintu cy'ingenzi mu mikorere y'imiti irwanya udukokookiside ya zinkiIngano niniokiside ya zinkiibuza mu buryo butaziguye kwiyongera kwa bagiteri zitera indwara nka Escherichia coli na Salmonella binyuze mu kurekura ubwoko bwa ogisijeni (ROS), ariko ikanateza imbere kwigarurira bagiteri nziza nka Lactobacillus.

3) Zinc nyinshi itera gukura kw'ingurube

Guhagarika igogora bituma igogora ry'ibiryo rigabanukaho 30%, kandi ubushobozi bwo kugogora intungamubiri mu ngurube zonsa burushaho kugabanuka iyo ziri mu mimerere yo gucibwamo. Ubushakashatsi bwagaragaje koibyokongeramo dose nyinshi zaokiside ya zinkiku ndyo bishobora kongera urugero rwa zinc mu maraso, kurushaho kugenzura isohoka rya peptides zo mu mara y'ubwonko n'imisemburo y'inzaranagushishikariza abana b'ingurube kurya. Muri icyo gihe kimwe, kwiyongera kwa zinc mu marasogishoboraguteza imbere neza imikorere n'imikorere ya enzymes zo mu igogora, kunoza igogorwa ry'intungamubirinakongera ibiro by'ingurube buri munsi.

IV. Gahunda yo Gushyira mu Bikorwa mu Buhanga n'Ingamba zo Kwirinda

1. Igipimo nyacyo n'uburyo bwo gukoresha neza

Nubwo bivugwa ko zinc nyinshi (1600-2500 mg/kg)okiside ya zinki) ibiryo bishobora gukoreshwa gusa muri"ibyumweru bibiri bya mbere nyuma yo gucutsa umwana", ubworozi bwinshi bw'ingurube bwongera igihe cyo gukoresha ibiryo byinshi bya zinc mu gihe cy'ibyumweru 2-8. Muri iki gihe, ubworozi bumwe bw'ingurube buzahura n'ikibazo"ingaruka mbi nyinshi za zinc", akenshi bigaragazwa n'umusatsi mwinshi kandi muremure n'uruhu rudasobanutse.

2. Hitamookiside ya zinkihamwe n'ubudahangarwa bwinshi kugira ngo binoze ingaruka z'umusaruro

Kuba bioavailability yaokiside ya zinkiikorwa n'uburyo bwo gutose iri hejuru cyane kurusha iyaokiside ya zinkibyakozwe n'inzira itaziguye. Bityo rero, iyo uhisemookiside ya zinkiibicuruzwa, inzira yo kubitunganya nayo igomba kwitabwaho.

5. Imiterere y'inganda n'icyerekezo cy'ikoranabuhanga ritandukanye

Nubwo EU yagabanyije ingano ya zinc yongeweho kuri 150 mg / kg, ibikorwa byo mu ngo bigaragaza ko gusimbuza burundu zinc nyinshi bigihura n'imbogamizi mu bya tekiniki. Ubundi buryo bugezweho nka nano bukoreshwa mu gusimbuza zinc nyinshi buracyafite ibibazo.okiside ya zinki(300 mg/kg) na zinc chloride y'ibanze (1200 mg/kg) bishobora kugabanya igipimo, ariko igiciro cyabyo kiri hejuru, uburyo ibintu bihagaze ntabwo bihagije, kandi umutekano w'igihe kirekire uracyakenewe kwemezwa. Kubwibyo,bisanzweokiside ya zinkini yo mahitamo meza ku mirima mito n'iciriritse kugira ngo ikiguzi n'ingaruka bibe biringaniye.
