INYANDIKO YUZUYE MU NZIRA NZIZA
Nkuko buriwese abizi, kurwanya gusaza birakenewekolageninyongera, ariko twese twirengagije ko kolagen nayo ikeneye kugumana.Niba udashobora kugumana kolagen, nubwo wongeyeho byinshi, bizabura.Kolagen igomba kuzuzwa no kugumana icyarimwe.
Ntibikenewe gusobanura icyo kolagen aricyo.Nibintu nyamukuru bigize uruhu rworoshye.Hariho ubwoko bwinshi bwa kolagen, nkubwoko bwa I, ubwoko bwa II, ubwoko bwa III, ubwoko bwa IV nibindi.Muri byo, muri rusange ubwoko bwa I kolagen mu ruhu rwabantu bakuru bwiganje rwose, bingana na 85% bya kolagen yabantu.
Hariho ubundi bwoko bubiri bwa kolagene ifite akamaro mukurwanya gusaza.Ubwoko bwa III kolagen iri hejuru cyane muruhu rwabana.Ibyo bakora ni net ya fibrous net.Niyo mpamvu abana bafite uruhu rworoshye.Hamwe no kwiyongera kwimyaka, andika III collagen ihinduka buhoro buhoro mubwoko bwa I kolagen, ikora ibiranga uruhu rwabantu bakuru.Kubwibyo, gutinda guhinduka kuva mubwoko bwa III kolagen kugeza mubwoko bwa I kolagen muruhu birashobora kongera ubwuzu bwuruhu kandi bikagabanya isura yimyaka yuruhu;Ubwoko bwa IV kolagen ni ikintu cyingenzi cya epidermal basement membrane, ishinzwe guhuza epidermis na dermis, kandi ni ngombwa no kurwanya inkari.
Nyamara, ingingo y'ingenzi: umurimo w'ingenzi wo kurwanya gusaza ni ukuzuza ubwoko bwa I kolagen.Ni ukubera ko ubwoko bwa I kolagen bugizwe na fibre nini ya eosinofilique, yitwa fibre ya kolagen, igumana uruhu rwuruhu kandi ikagira uburemere bwuruhu, kandi ikagira uruhare runini mugukomera kwuruhu no gukomera.
Ubwoko bwa I kolagen ifite iminyururu miremire itatu ya kolagen, ituma imiterere yayo ihagarara neza.Ikirenzeho, irashobora gufata imiterere ya kolagen.Umuyoboro wa kolagen fibre yakozwe mubwoko bwa I kolagen irakomeye kandi iroroshye, kuburyo ishobora gushyigikira imiterere ya kolagen.
Birashobora kuvugwa ko kuzuza ubwoko bwa kolagen I bikomeza mu buryo butaziguye urusobe rwa fibre ya kolagen mu ruhu kandi ni urufunguzo rwo gukomeza uruhu rukiri ruto.
