amakuru

Vuba aha, akanyamakuru k’ishuri ry’ubuvuzi rya kaminuza ya Gunma mu Buyapani kavuze ko ibitaro byateje cyanose mu bana benshi bavutse kubera umwanda w’amazi. Ubushakashatsi bwerekana ko n'amazi yungurujwe ashobora kwanduzwa atabishaka kandi ko abana bashobora kwandura methemoglobinemia.

Indwara ya Methemoglobinemia muri Neonatal ICU na Ward

Impinja icumi zavutse mu gice cyita ku bana bavuka no mu kigo cy’ababyeyi zabyaye methemoglobinemia biturutse ku kugaburirwa amata yakozwe n'amazi yanduye. Methemoglobine yibanze kuva kuri 9.9% kugeza kuri 43.3%. Abarwayi batatu bakiriye methylene yubururu (umwambi), igarura ubushobozi bwa ogisijeni ya hemoglobine, kandi nyuma yamasaha icyenda, abarwayi 10 bose basubiye mubisanzwe. Igishushanyo B cyerekana igishushanyo cya valve yangiritse n'imikorere isanzwe. Igicapo C cerekana isano iri hagati yo gutanga amazi yo kunywa hamwe nu muyoboro uzunguruka. Amazi yo kunywa ibitaro ava mu iriba kandi anyura muri sisitemu yo kweza hamwe na filteri yica bagiteri. Umurongo uzenguruka wo gushyushya utandukanijwe nogutanga amazi yo kunywa na cheque ya cheque. Kunanirwa kwa valve igenzura bituma amazi asubira mumurongo wo kuzenguruka ashyushye mumurongo wo gutanga amazi yo kunywa.

Isesengura ryamazi ya robine ryerekanaga nitrite nyinshi. Nyuma yiperereza ryakozwe, twasanze amazi yo kunywa yaranduye kubera kunanirwa na valve yatewe no gusubira inyuma kwa sisitemu yo gushyushya ibitaro. Amazi muri sisitemu yo gushyushya arimo ibintu birinda ibintu (Ishusho 1B na 1C). Nubwo amazi ya robine akoreshwa mugutegura amata y’uruhinja yahinduwe na filtri kugira ngo yujuje ubuziranenge bw’igihugu, muyungurura ntishobora gukuraho nitrite. Mubyukuri, amazi ya robine mubitaro byose yaranduye, ariko ntanumwe mubarwayi bakuze warwaye methemoglobine.

Ugereranije n’abana bakuru ndetse n’abantu bakuru, impinja zitarengeje amezi 2 zishobora kurwara methemoglobinose kuko impinja zinywa amazi menshi kuri kilo yuburemere bwumubiri kandi zikaba zifite ibikorwa bike bya NADH cytochrome b5 reductase, ihindura methemoglobine na hemoglobine. Byongeye kandi, pH nyinshi mu gifu cy’uruhinja ifasha kubaho kwa bagiteri zigabanya nitrate mu nzira yo hejuru igogora, ihindura nitrate kuri nitrite.

Uru rubanza rwerekana ko niyo formula yateguwe hakoreshejwe amazi ayungurujwe neza, methemoglobine irashobora guterwa no kwanduza amazi kubushake. Byongeye kandi, uru rubanza rugaragaza ko impinja zandura metemoglobine kurusha abantu bakuru. Kumenya ibi bintu nibyingenzi mukumenya inkomoko ya methemoglobine no kugabanya urugero rwicyorezo cyayo.
