Aside Arachidonic (ARA), aside docosahexaenoic (DHA) na aside eicosapentaenoic (EPA) ni aside fatty polyunsaturated fatty acids (LCPUFA) ifite uruhererekane rurerure. Carotenoids, harimo lutein na zeaxanthin (LZ), ziboneka cyane cyane mu mboga z’icyatsi.
ARA na DHA biboneka mu bwonko kandi ni bimwe mu bigize fosfolipide. Ubushakashatsi bwagaragaje ko kongeramo DHA na EPA bishobora kunoza imikorere y'ubwonko ku bantu bakuze.
Byongeye kandi, LZ, igice cy’ubwonko gitera antioxidant, byagaragaye ko gikora ku ngirabuzimafatizo z’imitsi, bityo bigira ingaruka ku mikorere y’ubwonko. Ariko, akamaro ka lutein na zeaxanthin ku mikorere y’ubwonko ntikazwi neza bitewe n’ibyavuye mu bushakashatsi bwakozwe mbere.
Hashingiwe ku kuba ARA, DHA, EPA, L na Z (LCPUFA + LZ) biri mu bwonko, ndetse na raporo zimwe na zimwe zigaragaza ko imikorere yo kwibuka yarushijeho kuba myiza, abanditsi b'ubushakashatsi bwakozwe ubu bavuze ko guhuza ibi bintu bishobora kunoza imikorere yo kwibuka. mu bwonko. ku bantu bakuze bafite ubuzima bwiza.
Abashakashatsi b’Abayapani bakoze ubushakashatsi bw’ibyumweru 24, bwakozwe ku buryo butaziguye, budafite ubumuga bwo mu mutwe, bugenzurwa na placebo, bukorwa mu matsinda atandukanye, ku ngaruka za LCPUFA + LH ku mikorere y’ubwonko ku bantu bakuze b’Abayapani bafite ibibazo byo kwibuka ariko badafite indwara yo kwibagirwa.
Nta tandukaniro rigaragara babonye hagati y’amatsinda. Ariko, mu isesengura ryakozwe ku itsinda ry’abitabiriye inama bafite ikibazo cyo kugabanuka k’ubushobozi bwo gutekereza, hagaragaye impinduka zikomeye.
Raporo isoza igira iti: “Ubu bushakashatsi bwerekana ku nshuro ya mbere ko guhuza LCPUFA na LZ bishobora kunoza imikorere y’ubwonko ku bantu bakuru bafite ubuzima bwiza bo mu Buyapani bafite ibibazo byo mu mutwe ariko badafite indwara yo kwibagirwa.” 'text ad1′); });
Abantu 120 baturutse i Tokyo n'uturere tuyikikije bashyizwe mu matsinda atatu: (1) itsinda rya placebo ryahawe placebo nk'inyongeramusaruro; (2) itsinda rya placebo ryahawe placebo nk'inyongeramusaruro; (2)). Itsinda rya LCPUFA+X ryahawe inyongeramusaruro igizwe na LCPUFA (irimo 120 mg ARA, 300 mg DHA na 100 mg EPA ku munsi) hamwe na Compound X (ntibyagaragajwe kuko iyi compound itari ivugwa muri ubu bushakashatsi)) (3) Itsinda rya LCPUFA+LH ryahawe inyongeramusaruro igizwe na LCPUFA (120 mg ARA, 300 mg DHA na 100 mg EPA ku munsi) hamwe na LH (10 mg lutein na 2 mg zeaxanthin ku munsi).
Ibiryo n'ibikoresho by'igerageza by'ubu bushakashatsi byatanzwe na Suntory Health Co., Ltd., icuruza ibiryo by'ubuzima birimo LCPUFA.
Igipimo cya kabiri cya Wechsler Logical Memory Scale II (WMS-R LM II) cyavuguruwe hamwe n'ikizamini cya Montreal Cognitive Test mu kiyapani (MoCA-J) byakoreshejwe mu gusuzuma.
Imyaka, igitsina, n'uburezi byanditswe nk'ibintu biranga abitabiriye ubushakashatsi. Ingero z'amaraso zakusanyijwe mu ntangiriro, ibyumweru bya 12 na 24 kugira ngo hakorwe isesengura rya aside irike na LZ.
Hakozwe isuzuma ry’imitsi n’ubwonko, hanyuma hapimwa aside irike ikomoka ku ndyo ku ntangiriro, mu byumweru 12 na 24. Buri wese mu bitabiriye yandikaga mu ikaye, yandika andi mafunguro anareba niba hari impinduka zikomeye mu mibereho ye.
Ibyavuye mu bushakashatsi byagaragaje ko LCPUFA + LZ nta ngaruka nini yagize ku mikorere yo kwibuka ku bantu bakuze bafite ubuzima bwiza mu Buyapani bafite ibibazo byo kwibuka, ariko iyi nyongeramusaruro yongereye imikorere yo kwibuka ku bantu bafite ibibazo byo gutekereza nabi.
Abanditsi bavuga ko inyigo z’ubutaha zishingiye ku bumenyi burambuye ku mikorere y’ibanze y’ibitekerezo by’abitabiriye zizafasha mu gufata ibyemezo bikwiye ku ngaruka z’ubu buryo ku mikorere y’ubwonko.
"Ingaruka za aside y'ibinure ya polyunsaturated ivanze na lutein na zeaxanthin ku kwibuka indwara z'ibicurane mu bantu bakuze bafite ubuzima bwiza"
