Gusaza k'uruhu ——Kwita ku ruhu

Imisemburo iragabanuka uko imyaka igenda ishira, harimo estrogen, testosterone, dehydroepiandrosterone sulfate, na hormone yo gukura. Ingaruka z'imisemburo ku ruhu ni nyinshi, harimo kwiyongera kwa collagen, kwiyongera k'ubugari bw'uruhu, no kwiyongera k'ububobere bw'uruhu. Muri byo, ingaruka za estrogen ziragaragara cyane, ariko imikorere y'ingaruka zayo ku turemangingo ntirasobanuka neza. Ingaruka za estrogen ku ruhu zigaragara cyane cyane binyuze muri keratinocytes zo mu bwoko bwa epidermis, fibroblasts na melanocytes zo mu bwoko bwa dermis, ndetse n'uturemangingo tw'umusatsi na sebaceous gland. Iyo ubushobozi bw'abagore bwo gukora estrogen bugabanutse, uruhu rusaza rurarushaho kwihuta. Ibura rya hormone estradiol rigabanya imikorere y'urwego rw'ibanze rwa epidermis kandi rigagabanya ikorwa rya collagen na elastic fibres, byose bikaba ari ingenzi mu kubungabunga uruhu. Kugabanuka kwa estrogen nyuma yo gucura ntibituma collagen igabanuka gusa, ahubwo no guhinduka k'uturemangingo tw'uruhu bigirwaho ingaruka no kuba estrogen nke nyuma yo gucura, kandi izi mpinduka zishobora gusubizwa inyuma vuba iyo estrogen ikoreshejwe mu mubiri. Ubushakashatsi bwemeje ko estrogen y’abagore ishobora kongera kolajeni, igakomeza ubunini bw’uruhu, kandi igakomeza ubushuhe bw’uruhu n’imikorere y’uruti rw’umurambararo rwa corneum binyuze mu kongera glycosaminoglycans na aside hyaluronic, bityo uruhu rugakomeza kumererwa neza. Biragaragara ko kugabanuka k’imikorere y’uturemangingo tw’umubiri na byo ari kimwe mu bintu by’ingenzi bigira ingaruka ku gusaza k’uruhu.

Kugabanuka kw'imisemburo iva muri pituitary, adrenal, na gonads bigira uruhare mu mpinduka ziranga umubiri n'uruhu ndetse n'imyitwarire ijyanye no gusaza. Urugero rwa serum rwa 17β-estradiol, dehydroepiandrosterone, progesterone, imisemburo ikura, hamwe n'imisemburo yabo ya insuline growth factor (IGF)-I igabanuka uko umuntu agenda akura. Ariko, urugero rwa serum ikura na IGF-I mu maraso y'abagabo ruragabanuka cyane, kandi imisemburo igabanuka muri bamwe mu baturage ishobora kubaho mu gihe cy'ubukure. Imisemburo ishobora kugira ingaruka ku miterere n'imikorere y'uruhu, ubushobozi bwo kwinjira mu ruhu, gukira, imiterere y'uruhu mu mubiri, no mu mikorere y'uruhu. Ubuvuzi bwo gusimbuza estrojeni bushobora gukumira gucura no gusaza k'uruhu.

Bityo rero, uko tugenda dukura, kwita ku ndwara z'uruhu bigomba kwiyongera buhoro buhoro. Dushobora gukoresha ababigize umwuga.ibikoresho byo gusesengura uruhukwitegereza no guhanura intambwe y'uruhu, guhanura ibibazo by'uruhu hakiri kare, no kubikemura mu buryo bufatika.
