Reka twige byose kuri elastin, ikenewe cyane ku mubiri wacu.

Ese wigeze wibaza uburyo uruhu rwacu rukura gutya, uburyo ibihaha byacu byiyongera nk'amabara hanyuma bikongera guhindagurika? Hari ikintu kidasanzwe mu mibiri yacu gifasha muri ibi byose. Ibyo nibyo tugiye kuvugaho uyu munsi. Ni poroteyine itangaje yitwa elastin.

Elastin ni iki mu by'ukuri?

Muri make, elastin ni poroteyine y'ingenzi cyane mu mubiri wacu. Ni nk'umukandara w'icyuma. Irashobora kuramburwa hanyuma igasubira ku ishusho yayo ya mbere. Elastin iboneka rwose mu ngingo z'umubiri wacu zikeneye koroherwa . Tekereza nawe, ibihaha byacu, uruhago, imiyoboro minini y'amaraso, n'imitsi imwe na imwe ifite elastin nyinshi. Hari kandi n'imwe mu mitsi iri mu ruhu no mu matwi yacu.

Ese Elastin na Kolajeni ni ibintu bitandukanye?

Yego, ntukivange ibi byombi. Elastin si kolagen. Ariko, kubera ko elastin na kolagen byombi ari poroteyine, hari igihe abantu bavanga ibi byombi. Mu by'ukuri, abahanga mu by'amateka, biga imiterere y'ingingo bakoresheje mikorosikopi, bakoresha amarangi yihariye kugira ngo babafashe kumenya itandukaniro. Iyo ayo marangi akoreshejwe, ahantu hari elastin nyinshi hasa n'umukara cyangwa umuhengeri.

Akamaro nyamukuru ka kolajeni ni uguha imibiri yacu imiterere, imbaraga, no gukomera. Tekereza nk'inkuta z'inzu yacu.

Akamaro nyamukuru ka elastin ni uguha ibice by'umubiri wacu ubushobozi bwo koroha, ni ukuvuga ubushobozi bwo guhindagurika. Igitangaje ni uko elastin irusha collagen inshuro zigera ku 1000 !

Elastine ikorwa ite?

Elastini igizwe na molekile nini kandi zoroshye zitwa tropoelastin. Ni nk'imigozi myinshi mito ihurira hamwe igakora umugozi munini kandi ukomeye.

Ni izihe nyungu za elastin ku mubiri wacu?

Akamaro nyamukuru ka elastin ni ugufasha ingingo z'umubiri wacu kwaguka no kwisubiraho ku ishusho yazo ya mbere.

• Ubufasha ku mutima: Dufite imitsi, imitsi y'amaraso itwara amaraso mu mibiri yacu. Iyi mitsi ikozwe muri elastine, ituma yoroha. Niyo mpamvu umutima wacu ushobora kohereza amaraso mu mibiri yacu mu buryo bworoshye. Uko imitsi igenda irushaho kwaguka, umuvuduko ku mutima uragabanuka.

• Ibihaha bimeze nk'umupira w'amapine:Elastini ituma ibihaha byacu bikora nk'udufuka duto. Iyo duhumeka, diaphragm yacu irakora. Ibi bitanga ingufu mu bihaha, zibikwa mu migozi ya elastini mu bihaha. Iyo duhumeka, izi ngufu zibitswe zirarekurwa, ibihaha bikongera bigakora. Ibi ni nko gukanda umupira w'ibara ry'umukara ukawureka.

• Ubuto bw'uruhu: Rambura ukuboko kwawe imbere hanyuma ushyireho uruhu ruto inyuma y'ukuboko kwawe nk'udupira mu masegonda make. Noneho rekura ukuboko kwawe. Niba uruhu rwawe rufite elastin nziza, uruhu rwawe ruzasubira inyuma vuba. Ariko, niba uruhu rwawe rufite elastin nkeya, bishobora gufata amasegonda make kugira ngo uruhu rwawe rwongere rugasubira inyuma. Uko tugenda dusaza, ingano ya elastin mu ruhu rwacu iragabanuka, ari nayo mpamvu uruhu rwacu rutangira kunyerera no kugorama.

Ni hehe elastin iboneka mu mubiri wacu?

Elastini iboneka cyane cyane mu ruhu, mu gice kiri munsi y'uruhu rwacu, mu bihaha, imitsi y'amaraso, imitsi, agahu ko mu gutwi, n'ibindi bice byinshi by'umubiri bisaba koroherwa.

Elastine isa ite kandi igizwe n'iki?

Hari ukutumvikana hagati y’abahanga mu bya siyansi ku miterere ya elastin. Bamwe bavuga ko iyo elastin yorohewe, ni ukuvuga iyo idakomeretse, isa n’urusobe rw’iminyururu ya polypeptide. Abandi bavuga ko iyi minyururu iba irimo akajagari, ariko ntabwo ari akajagari. Ariko, iyi miterere iragabanuka iyo irambuye, kuko icyo gihe iminyururu iba itondetse mu murongo ugororotse, mu gihe ikomeza gukomera no koroha.

Ubusanzwe insinga za elastini ziba zifite ibara ry'umuhondo.

Elastini igizwe na aside amine. Poroteyine igizwe na aside amine. Aside amine z'ingenzi muri elastine ni proline, glycine, desmosine, na isodesmosine . Izi ni urukurikirane rugufi, rusubiramo rwa aside amine eshatu kugeza ku icyenda zikora imiterere ikomeye kandi yoroshye.

Udupira tw’uruhu tw’umuntu mukuru tugizwe na 2% na 4% by’uburemere bw’uruhu rw’umuntu mukuru, nyuma yo gukuraho amavuta n’ubushuhe.

Ni izihe ndwara zigira ingaruka kuri elastin?

Ikibabaje ni uko hari indwara zimwe na zimwe zifata elastin. Reka turebere hamwe izo ari zo:

• Ateriosclerosis:Iki ni cyo gihe ibinure byiyongera mu mitsi yacu, bikayigabanya. Ibi bishobora gutera kubyimba kw'amaraso, indwara z'umutima, no gucika imitsi. Ubushakashatsi bwinshi ku bijyanye n'imitsi bwagaragaje ko ingano ya elastine karemano mu mitsi igabanuka.

• Cutis laxa: Iyi ni indwara ituma uruhu rutakaza ubushobozi bwarwo bwo kwiyoroshya. Ibi bishobora gutuma uruhu rurekura cyane kandi rugacika iminkanyari. Biragoye kandi kurambura no gusubira mu mwanya warwo wa mbere. Ibi akenshi biterwa n'impinduka mu ngirabuzimafatizo ya elastin.

• Emphysema: Iyi ni indwara y'ibihaha. Ikunze kugaragara ku bantu bamaze imyaka myinshi banywa itabi. Muri ibi, elastine mu bihaha iracika. Ibimenyetso birimo kugorwa no guhumeka, gukorora, gufunga igituza, umunaniro, no gukora impemu igihe kirekire.

• Supravalvular aortic stenosis (SVAS): Iyi ni indwara y'umutima ivukanwa. Iterwa no kugabanuka k'umuyoboro w'amaraso. Impinduka mu ngirabuzimafatizo ya elastin niyo itera SVAS.

• Indwara ya Williams: Iyi ni indwara idakunze kubaho cyane mu mikurire. Iterwa no kubura (ni ukuvuga igice cya gene kibura) kwa gene ya elastin na enzyme yitwa LIM kinase. Abantu barwaye syndrome ya Williams nabo bakunze kugira SVAS.

Ni ubuhe buryo bwo kuvura ibibazo bifitanye isano na elastine?

Hari uburyo butandukanye bwo kuvura bushobora gufasha kongera umusaruro wa elastine na kolajeni mu ruhu. Ariko, ubu buryo bukunze gukoreshwa mu kuvura ibibazo by'uruhu.

• Venus Viva™: Ubu ni uburyo bwo kuvura uruhu. Busaba gukoresha inshinge nto cyane zishyushye kugira ngo habeho utubuto duto mu ruhu. Uko uruhu rugenda rukira, hakorwa kolajeni nshya na elastine.

• Retinoide (ibikomoka kuri vitamine A): Retinoide, nka Retin-A®, zihutisha imikorere y'uruhu kandi zikongera umusaruro wa kolajeni na elastin.

Icy'ingenzi: Ni ngombwa kugisha inama umuganga wujuje ibisabwa mbere yo gutangira ubwo buryo bwose bwo kuvura. Si uburyo bwose bwo kuvura bukorera buri wese.

Uburyo bworoshye bwo gutuma elastine yacu ikomeza kuba nziza!

Elastin, hamwe na kolajeni, bifasha uruhu rwacu kugumana imbaraga kandi rworoshye. Dore ibintu byoroshye bishobora gufasha kugumana, ndetse wenda no kongera gato, ingano ya elastin mu ruhu rwacu:
