Ubururu bwa metilene mu kugabanya ibiro: gusuzuma ibimenyetso

Ntabwo byaremezwa ko ubururu bwa metilene ari umuti unyobwa ugabanya ibiro mu bantu. Ubushakashatsi bwabonetse mu gutegura iyi ngingo ntibugaragaza igerageza rigenzurwa ku bantu ryerekana ko kubunywa bituma ibinure bigabanuka kandi bigakomeza kuba bike. Harimo amagerageza ku mikorere y'umubiri, ibyavuye mu gupima ibiro by'inyamaswa, n'ubushakashatsi ku mubyibuho ukabije mu bantu aho iryo bara ryari rifite undi murimo.

Iryo tandukaniro rihindura igisubizo. Akaremangingo k'umwijima gakoresha ogisijeni nyinshi ni ikintu kigaragaza uburyo imikorere ishobora guhinduka. Ingurube yongereye ibiro bike nyuma y'igikorwa cy'igerageza ku gifu ni igisubizo cy'ubuvuzi bwageragejwe ku nyamaswa. Umuntu wagabanyije ibinure nyuma yo kuvurwa hakoreshejwe baloni yo mu gifu ni igisubizo cyabonetse mu muntu, ariko ntigitandukanya ingaruka z'ibara riri muri baloni n'iz'ibindi byakoreshejwe.

Ni iki cyafatwa nk'ikimenyetso cyo kugabanya ibiro?

Ibiro by'umubiri bigizwe n'ibinure, ingirangingo zitari ibinure, amagufwa, amazi, n'ibiri mu gifu no mu mara. Umubare muto ku munzani ntugaragaza igice cyahindutse. Ibipimo by'ibigize umubiri, nko gupima uko umubiri winjiza imirasire X y'ingufu ebyiri (DXA), bifasha gutandukanya uburemere bw'ibinure n'ubw'ingirangingo zoroshye zitari ibinure ndetse n'ubw'imyunyu ngugu yo mu magufwa. Nubwo bimeze bityo, ingirangingo zitari ibinure ntizisobanura imikaya ifatanye n'amagufwa gusa.

Ubushakashatsi bwatanga ibimenyetso bifatika ku kugenzura ibiro bwagereranya uburyo bw'ubuvuzi busobanuye neza mu bantu bagereranywa, bugapima impinduka mu gihe gihagije, bukazirikana imirire n'ibindi bikorwa, kandi bukagaragaza ingaruka mbi n'abavuye mu bushakashatsi. Bwatandukanya kugabanya ibiro umuntu asanganywe no kubuza ibiro kwiyongera, ndetse no kugabanuka kwa mbere no gukomeza kugumana ibiro byagabanutse.

Ibipimo by'imikorere y'umubiri bisubiza ibibazo bifite imbibi zirushijeho kuba nto. Ibinure byo mu mwijima bigaragaza ibinure byibitse muri urwo rugingo. Uko umubiri wakira insuline bigaragaza uko uyitabira. Ogisijeni ikoreshwa n'uturemangingo igaragaza igice cy'imikorere y'umubiri ijyanye n'ingufu mu bihe by'igerageza. Nta na kimwe gisimbura kugabanuka kw'ibinure mu bantu kwapimwe kandi gukomeza kubaho.

Kugereranya ibivugwa n'ubushakashatsi

Iri gereranya ritandukanya ibyapimwe n'ibyo umusomyi ashobora kubyitiranya na byo. Amahuza y'ubushakashatsi ajyana kuri raporo z'umwimerere cyangwa ku makuru yazo muri PubMed.

Ikivugwa gisuzumwa	Ubushakashatsi n'igikorwa cyageragejwe	Icyapimwe cyangwa cyatangajwe	Icyo igisubizo gishyigikira
“Butuma imikorere y'umubiri yiyongera, bityo bugatwika ibinure by'umubiri.”	Shin na bagenzi be, 2014: amagerageza ku turemangingo tw'umwijima no ku mbeba nto zagaburiwe indyo irimo ibinure byinshi; uburyo bwo gutanga ubururu bwa metilene bwarimo kubunywesha.	Kohereza ubutumwa mu turemangingo bijyanye na SIRT1/AMPK, ibipimo bya mitokondiriya, no kugabanuka kw'ibinure byibitse mu mwijima n'uburibwe bw'umwijima buherekejwe n'ibinure mu nyamaswa zageragejweho.	Igitekerezo gikeneye kugeragezwa ku mikorere y'umwijima. Ntibyemeza kugabanuka kw'ibiro mu bantu gukomeza kubaho.
“Ubushakashatsi ku mubyibuho ukabije bwemeje ko ubururu bwa metilene bugabanya ibiro.”	Lee na bagenzi be, 2022: igikoresho cyo mu gifu gisize ubururu bwa metilene hamwe n'ubuvuzi bwa fotodinamike butangizwa n'urumuri rwa lazere, mu ngurube.	Nyuma y'icyumweru kimwe, ukwiyongera kw'ibiro kwatangajwe kwari 12% ku zakorewe ubuvuzi bwa fotodinamike ugereranyije na 24% ku zo mu itsinda ryo kugereranya; urugero rwa ghrelin na rwo rwari hasi.	Kugabanya ukwiyongera kw'ibiro nyuma y'igikorwa gihuriza hamwe uburyo butandukanye ku nyamaswa. Impinduka zombi zatangajwe zari ukwiyongera kw'ibiro.
“Ubururu bwa metilene bwagabanyije ibiro butagabanyije ingano y'ibiribwa byaribwaga.”	Yang na bagenzi be, 2023: ubururu bwa metilene bwashyizwe mu gice cya mbere cy'urura ruto hamwe n'ubuvuzi bwa fotodinamike; incamake ivuga ko hakoreshejwe imbeba nini zagaburiwe indyo irimo ibinure byinshi mu kugerageza imikorere y'ubwo buvuzi.	Ibiro byari hasi ugereranyije n'itsinda ryakorewe igikorwa cyigana ubuvuzi nyuma y'iminsi 30, ibipimo bijyanye na glikoze byari byiza kurushaho, kandi nta tandukaniro rifatika ryagaragaye mu ngano y'ibiribwa byaribwaga.	Igisubizo cy'igikorwa cyo mu mara cyageragejwe mbere yo kugeragezwa ku bantu, si ikimenyetso gishyigikira kunywa ubururu bwa metilene nk'inyongera.
“Ubushakashatsi ku bantu bwapimye kugabanuka kw'ibinure hakoreshejwe ubururu bwa metilene.”	Itsinda ryakurikiranywe amezi atandatu rikoresha baloni yo mu gifu: baloni yarimo amazi y'umunyu n'ubururu bwa metilene; 39 muri 50 bitabiriye barangije igihe cyo gukurikiranwa.	DXA yagaragaje kugabanuka k'uburemere bw'ibinure n'ubw'ingirangingo zitari ibinure nyuma y'ubuvuzi bukoresha baloni.	Impinduka mu bigize umubiri w'abantu nyuma y'igikorwa gikoresha igikoresho. Ingaruka z'ibara ubwaryo ntizageragejwe.
“Igerageza ryo kugabanya ibiro ryagabanyije abantu mu matsinda ku buryo bwa tombola ryakoresheje iryo bara.”	Igerageza rya baloni aho abitabiriye bahinduranyaga uburyo kandi hakabaho igikorwa cyigana ubuvuzi cyo kugereranya: ibihe by'ubuvuzi bukoresha baloni n'iby'igikorwa cyigana ubuvuzi, biherekejwe n'ubuvuzi bushingiye ku mirire.	Kugabanuka kwa BMI n'ijanisha ry'ibiro by'ikirenga byagabanutse.	Ibimenyetso ku buryo bw'ubuvuzi bukoresha baloni muri rusange. Kugabanya abantu mu matsinda ku buryo bwa tombola ntibituma buri kintu cyakoreshejwe mu gikorwa kiba ari cyo gitanga ingaruka z'ubuvuzi.

Impamvu uburyo imikorere y'umubiri ihinduka budatanga igisubizo cya nyuma

Ubushakashatsi bwo mu 2014 ku mwijima ni intangiriro yumvikana y'igitekerezo gikeneye kugeragezwa mu binyabuzima. Mu turemangingo tw'umwijima, ubururu bwa metilene bwahinduye igipimo cya NAD+/NADH n'inzira zijyanye n'imikorere ya mitokondiriya no gutunganya ibinure. Igerageza ku mbeba nto ryamaze ibyumweru umunani zigaburirwa indyo irimo ibinure byinshi, kandi ryagaragaje ko ibinure by'ikirenga byibitse mu mwijima byari bike.

Ibyo ni ibimenyetso by'igerageza bifite akamaro ku ngirangingo runaka no ku buryo bw'igerageza bwigana indwara. Kwemeza ko bishobora gutuma ibinure by'umubiri wose bigabanuka bisaba izindi ntambwe: ingaruka zigomba kuboneka ku rugero umuntu ashobora kwihanganira, zigakomeza mu gihe cy'imirire n'ibikorwa bisanzwe, zigahindura ingufu umubiri ubika nyuma yo gukuramo izikoreshwa, kandi zigatanga igisubizo gifite akamaro mu buvuzi. Gupima intambwe ya mbere ntibishobora kwemeza izikurikiraho.

“ATP nyinshi” na byo ntibihagije nk'impamvu yo kwemeza kugabanuka kw'ibiro. ATP ni molekile itwara ingufu ikoreshwa n'uturemangingo. Uko ikorwa, ibitanga ingufu bikenerwa mu kuyikora, n'ingufu zose zikoreshwa buri munsi ni ingano zifitanye isano ariko zitandukanye. Ikivugwa ku mikorere myiza ya mitokondiriya gikeneye ibipimo bitaziguye mbere yo gukoreshwa mu kwemeza karori zakoreshejwe cyangwa ibinure byagabanutse.

Incamake yacu ku nyungu z'ubururu bwa metilene mu bushakashatsi ku bantu ikoresha iryo tandukaniro hagati y'uburyo bushoboka bw'imikorere n'inyungu yagaragaye ku murwayi.

Ibikorwa bitangizwa n'urumuri ni icyerekezo cyihariye cy'ubushakashatsi

Ubuvuzi bwa fotodinamike buhuza ikinyabutabire cyakira urumuri n'urumuri rutanzwe kugira ngo habeho ingaruka ku binyabuzima mu gice runaka. Mu bushakashatsi bwo mu 2022 ku ngurube, ubururu bwa metilene bwashyizwe mu gikoresho cyo mu gifu maze butangizwa n'urumuri rwa lazere. Igikorwa cyari kigizwe n'igikoresho, uko cyakoraga ku ngirangingo, ibara, n'urumuri. Gukuramo ibyo bice bihindura ubuvuzi buvugwa.

Raporo yo mu 2023 ku gice cya mbere cy'urura ruto yasuzumye ubuvuzi bwakorewe ahantu runaka mu mara kandi itangaza impinduka z'igihe gito ku dusongero two mu gice cya mbere cy'urura ruto. Umutwe wayo uvuga “uburyo bw'igerageza ku mbeba nto,” ariko incamake yayo ivuga imbeba nini zagaburiwe indyo irimo ibinure byinshi mu kugerageza ingaruka ku mikorere y'umubiri. Iryo tandukaniro mu gutangaza amakuru ni indi mpamvu yo gusoma uburyo bwakoreshejwe aho gukeka ibyakozwe hashingiwe ku mutwe gusa. Ibyo byagaragaye ntibishobora kuba impamvu yo guhuriza mu rugo kunywa iryo bara no gukoresha igikoresho gitanga urumuri rutukura.

Ibipimo byo kugabanuka kw'ibinure mu bantu bigomba kwitirirwa icyabiteye koko

Itsinda ryakurikiranywe amezi atandatu rikoresha baloni rigaragaza ibibazo bibiri bitandukanye mu gusobanura ibyavuye mu bushakashatsi. Mu bitabiriye barangije igihe cyo gukurikiranwa, ibiro byagabanutse ku mpuzandengo ya 11.7 kg. DXA yanditse kugabanuka ku mpuzandengo ya 7.53 kg mu buremere bw'ibinure na 3.70 kg mu buremere bw'ingirangingo zitari ibinure. Bityo impinduka yagaragaye ku munzani ntiyari iy'ibinure gusa.

Ikibazo cya kabiri ni ukwitirira impinduka icyaziteye. Abo bantu bahawe baloni yo mu gifu irimo amazi y'umunyu yashyizwemo ibara. Ntibagabanyijwe ku buryo bwa tombola mu itsinda rinywa ubururu bwa metilene n'irihabwa ikintu kidafite umuti. Ibipimo by'ibigize umubiri ni amakuru nyakuri yavuye ku bantu, ariko kwitirira izo mpinduka ubururu bwa metilene byaba ari ugusubiza ikibazo ubwo bushakashatsi butagerageje. Ububiko bw'ubushakashatsi bushyira ubushakashatsi mu byiciro hakurikijwe igikorwa cyageragejwe n'ibyavuyemo kugira ngo iryo tandukaniro rikomeze kugaragara.

Ese ibimenyetso bishyigikira kubunywa kugira ngo ugabanye ibiro?

Ibimenyetso byasuzumwe hano ntibyemeza inyungu yo kugabanya ibiro yagereranywa n'ibyago byo gukomeza kubunywa. Ikimenyetso cy'impinduka mu mikorere y'umubiri w'inyamaswa ntigishobora gutanga ingano cyangwa igihe cyo gukoresha bigira icyo bitanga mu bantu, kandi igikorwa gikoresha igikoresho ntigishobora gutanga gahunda yo kunywa.

Amakuru yo muri Amerika agenewe kwandika Provayblue iterwa mu mutsi agaragaza ko ikoreshwa ku methemoglobinemia umuntu agira nyuma yo kuvuka. Aburira ku kibazo gikomeye cya serotonin iyo ikoreshwa hamwe n'imiti igira ingaruka kuri serotonin n'imiti ya opioide, kandi abuza kuyikoresha mu gihe habuze G6PD kubera ibyago by'amaraso make aterwa no gusenyuka kw'insoro zitukura. Iyo miburo y'ubuvuzi ntiyemeza ko ibicuruzwa byo kunywa bigurishwa ku baguzi bitekanye. Igaragaza impamvu no gukoresha hagamijwe kugabanya ibiro bitaremezwa bisaba kwitondera imikorere y'imiti mu mubiri.

Ku muntu utekereza gukoresha ubururu bwa metilene kubera ko ibiro byahindutse nyuma yo gutangira undi muti, gusuzuma imiti bifite akamaro kurusha kongeraho ikinyabutabire kikiri mu igerageza. Suzuma ibimenyetso ku ngaruka mbi, ibihe bitagomba gukoreshwamo, n'imikoranire n'indi miti hamwe n'umuganga cyangwa umuhanga mu by'imiti. Ikivugwa gikwiriye gushingirwaho mu gufata icyemezo gikeneye igikorwa gisobanuye neza cyageragejwe ku bantu, ibipimo by'ibinure cyangwa ibiro, no gukurikirana kugaragaza niba inyungu ikomeza kubaho.
