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. Kwishakira ibisubizo byubusa, 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, isuka ya selile yamenetse hamwe n imyanda byinjira 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% ziterwa no gusaza no kwangirika bifitanye isano na radicals yubusa, harimo uruhu rwijimye rwijimye, iminkanyari, allergie, cataracte, kanseri, indwara z'umutima nibindi. Kuzuza buri munsi inzabibu za polifenole zirashobora gukuraho neza radicals zirenze urugero kandi bigatanga uburinzi bwamasaha 24 kumasemburo atandukanye yabantu.
2. Kuzimya ibibara no kwera uruhu
Duhereye ku mubiri: hamwe no gukura kwimyaka no kwanduza ibidukikije, umubiri wumuntu utanga umubare munini wa radicals yubusa, bikaviramo ihungabana ryimikorere ndetse na lipofuscine ikabije mumubiri. Inzira yayo 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 ngirabuzimafatizo z'uruhu (cyane cyane uruhu rwo mu maso no mu ntoki), ikora ibibara by'uruhu, chloasma, ikinyugunyugu n'ibibara bya senile, bigira ingaruka zikomeye ku isura y'abarwayi kandi bigatera abarwayi ububabare bukabije bwo mu mutwe. Imizabibu polifenol proanthocyanidins izwi nka '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 kwirinda radicals yubuntu.
Uhereye hejuru yuruhu: umwuka wanduye, ultraviolet ikomeye nimirasire ya mudasobwa, kwisiga (ibirungo, imiti igabanya ubukana, pigment) nibindi bintu nibyo ntandaro yo kubyara radicals exogenous free radicals, nayo ituma hanze yingirangingo zuruhu zigira ibitero byinshi . Muburyo bwo kwibasirwa nubusa no gusenya ingirabuzimafatizo, umubare munini wingirabuzimafatizo zipfa no guhindagurika kwa metabolike, kandi umwanda uri mu ngirabuzimafatizo ntushobora guhindagurika, bikaviramo kwibika pigment, Umubare w'ingirabuzimafatizo nshya uragabanuka cyane (selile nshya ni ngombwa ikintu cyo gukomeza ubuzima bwuruhu). Umuzabibu wa proanthocyanidine ntushobora gukuraho gusa radicals yubusa mumubiri wumuntu, ariko kandi uteza imbere metabolisme yuruhu, gutandukanya umwanda w’ibidukikije no kwangiza amavuta yo kwisiga, kubora melanine no kugera ku ngaruka zo kwera uruhu. 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 ishyirwaho ryambukiranya rya kolagen; Ku rundi ruhande, nk'igikoresho cyiza cya radical scavenger, kirashobora gukumira "kurenga guhuza" uruhu, kurinda isura y'iminkanyari y'uruhu n'inkovu, kandi bigakomeza uruhu rworoshye kandi rworoshye. Imizabibu polifenol proanthocyanidine irashobora kandi gukumira umusaruro wa elastase ikomeye, ikabuza ibikorwa byayo, kandi ikarinda radicals yubusa cyangwa elastase ikomeye gutesha agaciro 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
