Kimwe mu bice by'umubiri bitazwi cyaneubuvuzi bworohejeUbushakashatsi bwakorewe ku mitsi. Imitsi y'umuntu ifite sisitemu yihariye cyane yo gukora ingufu, ikenera kuba ishobora gutanga ingufu haba mu gihe kirekire cyo gukoresha nabi ndetse no mu gihe gito cyo gukoresha cyane. Ubushakashatsi muri uru rwego bwihuta cyane mu myaka ibiri ishize, hamwe n'ubushakashatsi bushya bwinshi buri kwezi. Umucyo utukura n'urumuri rwa infrared byigwa cyane ku ndwara zitandukanye n'ibibazo, kuva ku bubabare bw'ingingo kugeza ku gukira kw'ibikomere, birashoboka ko bitewe n'uko ingaruka z'uturemangingo zitekerezwaho gukora ku rwego rw'ibanze rw'ingufu. None se niba urumuri rwinjira mu mitsi, rushobora kugira ingaruka nziza? Muri iyi nkuru tuzasuzuma uburyo urumuri rukorana n'izi sisitemu n'inyungu rushobora kuzana, niba zihari.
Umucyo ushobora kugira ingaruka ku mikorere y'imitsi, ariko se ubigenza ute?
Kugira ngo dusobanukirwe uburyo urumuri rushobora kugira ingaruka ku mitsi, tugomba kubanza gusobanukirwa uburyo imitsi ikora. Ingufu ni ngombwa ku buzima muri buri turemangingo twa buri bwoko tuzi ubu. Iki kintu cy’ubuzima kigaragara cyane mu mitsi, mu buryo bw’ikoranabuhanga, kurusha ubundi bwoko bwose bw’imitsi. Kubera ko imitsi igira uruhare mu kugenda, igomba kuba irimo gukora no gukoresha ingufu, bitabaye ibyo ntizagenda. Ikintu cyose gifasha muri ubu buryo bw’ingufu bw’ibanze kizaba gifite agaciro.
Uburyo bwo kuvura hakoreshejwe urumuri
Ubuvuzi bw'urumuri bufite uburyo buzwi cyane mu turemangingo twose tw'umubiri hamwe na mitochondria (mitochondria ikaba ari organelles zishinzwe gukora ingufu). Ushobora kureba muri Cytochrome C Oxidase na Nitric Oxide kugira ngo umenye byinshi kuri ibi, ariko mu by'ukuri igitekerezo ni uko urumuri rw'umutuku n'urumuri rwo hafi ya infrared bifasha mitochondria yacu kurangiza igikorwa cyo guhumeka, bigatanga CO2 na ATP (ingufu). Ibi byakoreshwa hafi mu turemangingo twose tw'umubiri, usibye utudafite mitochondria nka selile zitukura.
Isano hagati y'imitsi n'ingufu
Kimwe mu bintu by'ingenzi biranga uturemangingo tw'imitsi ni uko tuba twinshi cyane muri mitochondria, bikaba bikenewe ko duhaza ingufu nyinshi zikenewe. Ibi bireba imitsi y'amagufwa, imitsi y'umutima, n'imitsi yoroshye nk'uko wabibona mu ngingo z'imbere. Ubucucike bwa mitochondria mu mitsi buratandukanye bitewe n'ubwoko n'ibice by'umubiri, ariko byose bikenera ingufu nyinshi kugira ngo bikora. Kuba bihari muri rusange bigaragaza impamvu abashakashatsi ku buvuzi bw'urumuri bashishikajwe no gukoresha imitsi yo kwibandaho, ndetse kurusha izindi ngingo.
Uturemangingo tw’imitsi - gukura no gusana byongerewe imbaraga n’urumuri?
Uturemangingo twa Myosatellite, ubwoko bw'uturemangingo tw'imitsi tugira uruhare mu gukura no gusana, na two ni intego y'ingenzi ishobora guterwa n'ubuvuzi bw'urumuri1,5, ndetse wenda n'intego nyamukuru itanga ingaruka z'igihe kirekire. Utu turemangingo tw'urumuri dutangira gukora bitewe n'ingufu (nk'izituruka ku mikorere y'imashini nk'imyitozo ngororamubiri cyangwa imvune) - inzira ishobora kongerwamo imbaraga hakoreshejwe ubuvuzi bw'urumuri9. Kimwe n'uturemangingo tw'urumuri ahantu hose mu mubiri, utwo turemangingo tw'urumuri ni two tubanza uturemangingo tw'imitsi dusanzwe. Akenshi tuba mu mimerere yo kuruhuka, idakora, ariko tuzahinduka utundi turemangingo tw'urumuri cyangwa tugahinduka uturemangingo tw'imitsi dukora neza nk'igice cy'inzira yo gukira, mu rwego rwo gusubiza imvune cyangwa ihungabana ry'imyitozo ngororamubiri. Ubushakashatsi buherutse bwerekana ko ingufu za mitochondria mu turemangingo tw'urumuri ari zo zigenzura iherezo ryazo6, ahanini zigagena 'igenamigambi' ryazo ndetse n'umuvuduko wazo n'imikorere yazo. Kubera ko igitekerezo kiri inyuma y'ubuvuzi bw'urumuri ari uko gishobora kuba ikintu gikomeye giteza imbere imikorere ya mitochondria, hariho uburyo busobanutse bwo gusobanura uburyo urumuri rushobora kunoza imikurire yacu no gusana imitsi binyuze mu turemangingo tw'urumuri.
Ububyimbirwe
Kubyimba ni ikintu gisanzwe kijyana no kwangirika kw'imitsi cyangwa stress. Abashakashatsi bamwe batekereza ko urumuri rushobora gufasha (nirukoreshwa neza) kugabanya ubukana bw'ububyimba3 (binyujije mu kongera urugero rwa CO2 - hanyuma bikabuza cytokines/prostaglandins kubyimba), bityo bigatuma habaho gusana neza nta nkovu/fibrosis.
