Procyanidins (OPC), izina ry'ubushinwa, ni ubwoko bwa bioflavonoide ifite imiterere yihariye ya molekile.Irazwi ku rwego mpuzamahanga nka antioxydants isanzwe ikora neza kugirango isukure radicals yubusa mumubiri wumuntu.
1. Gukata radical yubusa, antioxydeant no kurwanya gusaza
Radicals yubusa isenya ingirabuzimafatizo, bikaviramo guhindagurika no guturika kwa selile, kugirango selile idashobora gukuramo imirire iturutse hanze, cyangwa ngo isohore imyanda ya metabolike muri selile, kandi itakaza imbaraga zo kurwanya bagiteri na virusi.Nyuma yo guturika kwingirangingo, amazi yamenetse yamenetse hamwe n imyanda yinjira mumwanya wa selile, bigatera reaction zo hanze nko gutwika, kubabara, gutukura no kubyimba.Ingirabuzimafatizo nyinshi ziraturika na apoptose, biganisha ku kugabanuka no gutesha agaciro imikorere yuruhu, imitsi, ingingo zimbere nizindi ngingo ningingo.Radical radicals nimwe mubintu byingenzi bitera gusaza kwabantu nindwara nyinshi.Indwara zigera kuri 80% ~ 90% zisaza no kwangirika zifitanye isano na radicals yubuntu, harimo gushira uruhu rwijimye, uruhu, allergie, cataracte, kanseri, indwara z'umutima nibindi.Kuzuza buri munsi inzabibu za polifenole zirashobora gukuraho neza radicals zirenze urugero kandi zigatanga uburinzi bwamasaha 24 kumasoko atandukanye yabantu.
2. Kuzimya ibibara no kwera uruhu
Duhereye ku buryo bw'umubiri: hamwe no gukura kw'imyaka no kwanduza ibidukikije, umubiri w'umuntu utanga umubare munini wa radicals yubusa, bikaviramo indwara ya metabolike ndetse na lipofuscine ikabije mu mubiri.Inzira yacyo yo kubora irahagaritswe, kandi lipofuscine nyinshi ishyirwa mumutima, umwijima, impyiko, ibihaha, impyiko, ubwonko nubwonko bwimitsi, bikora ibibara bya lipofuscine, byangiza ingingo nimirimo igabanuka;Lipofuscine ishyirwa mu ngirangingo z'uruhu (cyane cyane uruhu rwo mu maso no mu ntoki), ikora ibibara by'uruhu, chloasma, ikinyugunyugu hamwe n'ibibara bya senile, bigira ingaruka zikomeye ku isura y'abarwayi kandi bigatera abarwayi ububabare bukabije bwo mu mutwe.Imizabibu polifenol proanthocyanidins izwi nk '' imbaraga zikomeye za radical scavenger '.Irashobora kubora lipofuscine, ikarinda ingingo zitandukanye kandi ikagabanya ibibara byamabara mumubiri.Byongeye kandi, bitandukanye na antioxydants isanzwe, procyanidine irashobora kurenga inzitizi yubwonko bwamaraso kandi ikarinda ubwonko nimiyoboro yamaraso radicals yubusa.
Uhereye hejuru yuruhu: umwuka wanduye, ultraviolet ikomeye hamwe nimirasire ya mudasobwa, kwisiga (ibirungo, imiti igabanya ubukana, pigment) nibindi bintu nibyo ntandaro yo kubyara radicals exogenous free radicals, nayo ituma hanze yingirangingo zuruhu zibasirwa cyane .Muburyo bwo kwibasirwa nubusa no gusenya ingirabuzimafatizo, umubare munini wingirabuzimafatizo zipfa no guhindagurika kwa metabolike, kandi umwanda uri mu ngirabuzimafatizo ntushobora guhindagurika, bikavamo kwibiza kwa pigment, Umubare wingirabuzimafatizo nshya uragabanuka cyane (selile nshya ningirakamaro ikintu cyo gukomeza ubuzima bwuruhu).Imizabibu proanthocyanidins ntishobora gukuraho gusa radicals yubusa mumubiri wumuntu, ariko kandi iteza imbere metabolisme yuruhu, gutandukanya umwanda w’ibidukikije no kwangiza amavuta yo kwisiga, kubora melanine no kugera ku ngaruka zuruhu rwera.Procyanidin OPC ni ikintu gisanzwe gitwikira izuba, gishobora kurinda imirasire ya ultraviolet kwangiza uruhu.Imirasire y'izuba hamwe na ultraviolet irashobora kwica 50% by'uturemangingo tw'uruhu rw'umuntu, ariko uramutse ufashe polifenole yinzabibu kugirango urinde, hafi 85% by'uturemangingo twuruhu dushobora kurokoka urupfu kandi 'bikarinda izuba'.
3. Komeza ubworoherane bwuruhu no kugabanya iminkanyari
Dermis yuruhu ni iyumubiri uhuza.Kolagen na elastine ikomeye irimo birimo bigira uruhare runini muburyo bwose bwuruhu.Imizabibu polifenol proanthocyanidine igira uruhare runini muruhu: kuruhande rumwe, irashobora guteza imbere gushiraho guhuza kwiza kwa kolagen;Ku rundi ruhande, nk'igikoresho cyiza cya radical scavenger, kirashobora gukumira "kurenga guhuza" uruhu, kurinda isura yiminkanyari zuruhu ninkovu, kandi bikagumisha uruhu neza kandi neza.Imizabibu polifenol proanthocyanidine irashobora kandi gukumira umusaruro wa elastase ikomeye, ikabuza ibikorwa byayo, kandi ikarinda radicals yubusa cyangwa elastase ikomeye kwangiza poroteyine zikomeye, kugirango imbere imbere ubuzima bwuruhu, kugabanya indwara zuruhu n’iminkanyari, ndetse bikureho inkovu.
4. PMS (syndrome de premenstrual)
Umugore wese ntazaba amenyereye PMS (syndrome de premenstrual).Ibimenyetso rusange bya PMS ni: kubabara, kubyimba amabere, inda itaringaniye, kuribwa mu maso, ububabare butagaragara, kubyibuha, kudakora neza ukuguru, guhungabana mumarangamutima, kwishima, kurakara, kwiheba no kubabara umutwe.Ibi bimenyetso bituruka kumyitwarire isanzwe yumubiri yumubiri kugeza kurwego rwa estrogene na progesterone mumubiri
