“Byose bikura bitewe n’izuba”. Umucyo w’izuba urimo uruvange rw’urumuri, buri rumuri rufite uburebure butandukanye, rugaragaza ibara ritandukanye. Ibi biterwa nuko umucyo ujya mu bice by’umubiri kandi ukagira ingaruka zitandukanye ku binyabuzima.
Porofeseri Michael Hamblin wo mu Ishuri ry’Ubuganga rya Harvard yasohoye inyandiko z’ubushakashatsi zigaragaza ko urumuri rutukura rushobora gutera ingaruka zitandukanye z’ubushyuhe, ingaruka za fotokemike, n’izindi ngaruka za biyoloji. Rushobora kandi kwinjira mu ngingo z’umuntu kugeza kuri mm 30 cyangwa zirenga, ku miyoboro y’amaraso, imiyoboro ya lymphatic, impera z’imitsi, n’ingingo ziri munsi y’umubiri. Ibi biterwa nuko urumuri rutukura nk’uru rutaboneka mu bundi bwoko bw’urumuri, bityo rukaba ruzwi nka "idirishya ry’urumuri" ry’uruhu rw’umuntu.
Umubiri winjizwa n'urumuri rutukura gute?
Mu ngingo z'umubiri wacu, urumuri rwinjizwa cyane cyane na poroteyine, ibara ry'uruhu, n'izindi molecule nini, ndetse na molecule z'amazi. Kubera ko molecule z'amazi na hemoglobine biri mu gice cy'urumuri rutukura rw'ikigereranyo cyo kwinjiza urumuri ari bito, fotoni zishobora kwinjira cyane mu ngingo kugira ngo zigire ingaruka nziza ku buvuzi. Urumuri rutukura n'umubiri w'umuntu ni byo byegereye imirasire y'imirasire ya electromagnetic, kandi bizwi kandi nka "urumuri rw'ubuzima"! Bizwi kandi nka "urumuri rw'ubuzima".
Raporo y'Ubushakashatsi Imbonerahamwe ya 2 Gufata amabara atandukanye y'urumuri n'uturemangingo tw'uruhu. Byongeye kandi, ku rwego rw'uturemangingo, mitochondria ni yo ifata urumuri rutukura cyane. Umucyo utukura usa n'uwo muri mitochondria ufata, kandi fotoni zinjira mu mubiri w'umuntu, bigatuma habaho uburyo bwiza bwo gukora ikoranabuhanga rya fotochemical - uburyo bwa enzyme. Ubu buryo bwongera imikorere ya mitochondria catalase, superoxide dismutase n'izindi enzymes zijyanye no gukora ingufu, zihutisha ikorwa rya ATP, zikongera ingufu zitangwa n'uturemangingo kandi zikihutisha inzira yo gukora imikorere no gukuraho uburozi mu mubiri. Bituma umubiri wihuta uburyo imikorere yawo ikanakurwaho uburozi.
Mitochondria ni zo zifata urumuri rutukura cyane ku rwego rwa selile. Urumuri rutukura rusa n'urumuri rwa mitochondria, kandi fotoni zinjira mu mubiri w'umuntu, bigatuma habaho uburyo bwiza bwo gukora ikoranabuhanga rya fotochemical - uburyo bwa enzyme. Ubu buryo bwongera imikorere ya mitochondria catalase, superoxide dismutase n'izindi enzymes zijyanye no gukora ingufu, zikihutisha ikorwa rya ATP, zikongera ingufu zitangwa n'uturemangingo kandi zikihutisha inzira yo gukora imikorere y'umubiri no gukuraho uburozi mu mubiri. Bituma umubiri wihuta mu gukora imikorere y'uburozi no kubukuraho.
Ubundi bushakashatsi bwerekana ko imirasire y'urumuri rutukura ishobora guhindura uburyo gene zijyanye n'isukari, lipide na poroteyine zikoreshwa, bigatuma fibroblasts zikoresha aside irike nk'ibikoresho fatizo byo gukora ATP, bityo bikihutisha imikorere y'ibinure; kandi icyarimwe, bishobora no gutuma gene zijyanye n'ingufu zikoreshwa mu gukora imiterere y'ingufu ziyongera, nka NADH dehydrogenase, ATP synthetase, na poroteyine za flavin zitwara electron, zifasha mu gusana no kuvugurura ingirangingo zangiritse, no gukangura ingirangingo z'imitsi kugira ngo zigere ku ntego yo kuvura. Bishobora kandi gukangura ingirangingo z'imitsi kugira ngo zigere ku ntego yo kuvura.
Uburyo bushoboka bwo kurinda ubwonko buterwa n'urumuri rutukura
Ingaruka z'urumuri rutukura ku mubiri w'umuntu
Hari ingingo nyinshi n'igeragezwa ry'ubuvuzi ku buryo urumuri rutukura rugira ingaruka ku bwiza, gukira no ku budahangarwa bw'umubiri. Binagira uruhare runini mu gutuma corpus luteum ikorwa mu ntangangore, ikagenzura ikorwa ry'imisemburo y'imibonano mpuzabitsina, ikanoza icyerekezo cyo kureba, ikagabanya ibiro n'ibinure, kandi ikagabanya amarangamutima.
Umucyo utukura ushobora kunoza ibara ry'uruhu. Ubundi bushakashatsi bwagaragaje ko urumuri rutukura rushobora kubuza imikorere ya tyrosinase, ari yo enzyme ifasha mu gukora ibara ry'uruhu. Rushobora kandi gukora poroteyine yitwa extracellular regulated protein kinase, ishobora kugabanya ikorwa rya tyrosinase n'izindi poroteyine zifitanye isano. Ibi bishobora gufasha kunoza ibara ry'uruhu no kugabanya ibibazo byo kugaragara kw'amabara, nk'uduheri, ibiheri, n'ibindi bihinduka ibara ry'uruhu.
1. Umucyo utukura utuma ibara rihinduka neza
Urumuri rutukura rworohereza gukomeza gukora imyitozo ngororamubiri nubwo waba unaniwe. Abashakashatsi basanze urumuri rutukura mu minota 20 rushobora kongera urugero rwa ogisijeni mu maraso no kugabanya ikoreshwa ry'ingufu ziterwa n'umwuka mubi, bigatuma aside lactic igabanuka mu gihe cy'imyitozo ngororamubiri. Ibi bishobora kugabanya cyane umunaniro no kunoza ubushobozi bw'umubiri bwo kurwanya umunaniro no kwihangana.
2.Urumuri rutukura rwongerera imbaraga ubudahangarwa n'umunaniro
Umucyo utukura ushobora kandi gufasha mu kubura amaso. Ubushakashatsi bwakozwe n'abahanga mu bya siyansi b'Abongereza mu kinyamakuru Scientific Reports bwagaragaje ko kuba umuntu ahura n'urumuri rwinshi rutukura mu gihe cy'iminota itatu gusa ku munsi bishobora kugabanya cyane ubutabazi bw'amaso, aho kureba kwabo birushaho kuba byiza ku kigero cya 17%.
