Amababi ya selile yangiza abantu?

Amababi ya selile, azwi kandi nka carboxymethyl selulose (CMC), ni inyongeramusaruro y'ibiribwa ikoreshwa cyane nk'ibyimbye, stabilisateur, na emulisiferi mu biribwa byinshi bitunganijwe, amavuta yo kwisiga, n'ibicuruzwa bya farumasi. Bikomoka kuri selile, polymer karemano igizwe nurukuta rw'utugingo ngengabuzima, kandi ihindurwa mu buryo bwa shimi kugirango ireme ibintu bimeze nk'amenyo.

Habayeho impungenge z’umutekano w’amavuta ya selile mu myaka yashize, ubushakashatsi bumwe bwerekana ko bushobora kugira ingaruka mbi ku buzima bw’abantu. Muri iki kiganiro, tuzasesengura ubushakashatsi ku menyo ya selile ndetse n’ingaruka zishobora guteza ubuzima bwa muntu.

Ubushakashatsi bwuburozi kuri selile ya selile

Habayeho ubushakashatsi bwinshi ku burozi bwa selile ya selile, haba mu nyamaswa ndetse no mu bantu. Ibyavuye muri ubwo bushakashatsi byavanze, bamwe bavuga ko sakile ya selile ifite umutekano muke, mugihe abandi bagaragaje impungenge z’ingaruka zishobora guterwa.

Ubushakashatsi bumwe bwasohotse mu kinyamakuru cy’ubumenyi n’ikoranabuhanga mu mwaka wa 2015 bwerekanye ko amase ya selile afite umutekano muke mu mbeba, ndetse no kuri dosiye nyinshi. Ubushakashatsi bwerekanye ko imbeba zagaburiwe ibiryo birimo selile ya selile kugeza kuri 5% mu minsi 90 nta kimenyetso cyerekana uburozi cyangwa ingaruka mbi ku buzima.

Ubundi bushakashatsi bwasohotse mu kinyamakuru cy’uburozi n’ubuzima bushingiye ku bidukikije mu 2017 bwasuzumye ubumara bw’amavuta ya selile mu mbeba kandi busanga nta kimenyetso cyerekana uburozi cyangwa ingaruka mbi, ndetse no ku kigero cya 5% by’imirire y’inyamaswa.

Ariko, ubundi bushakashatsi bwateje impungenge z'umutekano wa selile. Ubushakashatsi bwasohotse mu kinyamakuru cy’ubuzima bw’umwuga mu 2005 bwerekanye ko guhumeka kwa selile yateje ibimenyetso by’ubuhumekero ku bakozi bo mu ruganda rukora amavuta ya selile. Ubushakashatsi bwagaragaje ko guhumeka amenyo ya selile bishobora gutera guhumeka no gutwika, inasaba ko abakozi barindwa.

Ubushakashatsi bwasohotse mu kinyamakuru mpuzamahanga cy’uburozi mu mwaka wa 2010 bwerekanye ko sakile ya selile yari genotoxique muri lymphocytes zabantu, ari zo ngirabuzimafatizo z’amaraso zifite uruhare runini mu mikorere y’umubiri. Ubushakashatsi bwerekanye ko guhura n’ibibyimba byinshi bya selile yangiza ADN kandi byongera inshuro zidasanzwe za chromosomal muri lymphocytes.

Ubundi bushakashatsi bwasohotse mu kinyamakuru cyitwa Applied Toxicology mu mwaka wa 2012 bwerekanye ko sakile ya selile yari uburozi ku ngirabuzimafatizo z'umwijima z'umuntu muri vitro, bigatuma abantu bapfa ndetse n'indi mpinduka.

Muri rusange, ibimenyetso byuburozi bwa selile yivanze. Nubwo ubushakashatsi bumwe bwasanze nta kimenyetso cyerekana uburozi cyangwa ingaruka mbi ku buzima, abandi bagaragaje impungenge z’ingaruka zishobora guterwa, cyane cyane ku bijyanye n’ingaruka z’ubuhumekero n’irondakoko.

Ibishobora Kubangamira Ubuzima bwa Cellulose

Mugihe ibimenyetso byerekana uburozi bwa selile ya selile bivanze, hari ingaruka nyinshi zishobora gutera ubuzima zijyanye no gukoresha ibiryo nibindi bicuruzwa.

Imwe mu ngaruka zishobora kubaho ni amahirwe yo guterwa no guhumeka no gutwika, cyane cyane ku bakozi bahura n’umukungugu mwinshi wa selile. Abakozi bakora mu nganda nko gukora impapuro no gutunganya ibiryo barashobora guhura n’umukungugu mwinshi wa selile ya selile, ibyo bikaba bishobora gutera ibimenyetso byubuhumekero nko gukorora, kuniha, no guhumeka neza.

Iyindi ngaruka ishobora guterwa na selile yamashanyarazi nubushobozi bwayo bwo kwangiza ADN hamwe na chromosomal idasanzwe, nkuko byagaragajwe nubushakashatsi twavuze haruguru. Kwangirika kwa ADN hamwe na chromosomal idasanzwe birashobora kongera ibyago bya kanseri nizindi ndwara.

Byongeye kandi, ubushakashatsi bumwe na bumwe bwerekanye ko amase ya selile ashobora kubangamira iyinjizwa ryintungamubiri mu nzira yigifu, cyane cyane imyunyu ngugu nka calcium, fer, na zinc. Ibi birashobora gutuma habaho intungamubiri zintungamubiri nibibazo byubuzima bijyanye.
