Shaaha cagaaran waa isha dhalinyarada leh ee u muuqda awood caafimaad oo aan dhammaad lahayn, gaar ahaan Aasiya. Sababtoo ah cabitaanka qaranka Japan kaliya kuma habboona ka hortagga kansarka, sun-saarista, iyo xoojinta wadnaha iyo xididdada, sidoo kale waxay kicisaa soo saarista unugyada cusub ee maskaxda, kuwaas oo hagaajin kara xusuustaada, sahlaysa inaad barato waxyaabo cusub, kana hortagto ama hoos u dhigto. horumarinta asaasaqa. Haddii aadan jeclayn shaaha cagaaran, waxaad sidoo kale qaadan kartaa shaaha cagaaran oo laga soosaaray qaab kaabsal ah.
Shaaha cagaaran waxa uu kiciyaa samaynta unugyada dareemayaasha ee maskaxda ee cusub
Ma ogtahay taas? Koob shaah cagaaran ah ka dib, madaxa ayaa si buuxda u caddaaday. Waxaad awood u yeelan kartaa in si ka wanaagsan oo hawlo maskaxiyan u baahan ay aad u sahlanaato in la dhammaystiro. La yaab ma laha tan iyo mid ka mid ah maaddooyinka ugu muhiimsan ee shaaha cagaaran - epigallocatechin gallate, ama EGCG gaaban - waxay kicin kartaa samaynta unugyada dareemayaasha cusub ee maskaxda (neurogenesis), daraasad dib loo helay 2012.
Ilaa laga soo bilaabo 1990-meeyadii, waxaa la aaminsanaa in samaynta unugyada dareemayaasha cusub ee maskaxdu ay tahay mid aan macquul ahayn dadka waaweyn. Dhanka kale, si kastaba ha ahaatee, waxaan ognahay in unugyada dareemayaasha ay sidoo kale sameyn karaan marar badan iyo mar kale dadka waaweyn - xitaa da'da. Sidaa darteed waa awoodda maskaxda ee cimriga oo dhan. Waxa kale oo loo yaqaan caagnimada neural, taas oo macnaheedu yahay in maskaxda iyo qaab-dhismeedkeedu isbeddeli karaan, kobcin karaan, oo la qabsan karaan hadba sida loo baahdo, sida markaad wax cusub barato, ha noqoto maskaxeed (tusaale luqad, cayaar, ama aragtida shatiga badmaaxa) ama dabeecad jidheed (tusaale isboorti cusub, jimicsi cusub).
Shaaha cagaaran ee ka hortagga iyo daaweynta waallida
Marka laga hadlayo cudurrada neurodegenerative sida waallida ama hoos u dhaca waxqabadka xusuusta, balaastigga neerfaha iyo sidaas awgeed sameynta unugyada cusub ee dareemayaasha ayaa hoos u dhacaya. Haddii EGCG laga bilaabo shaaha cagaaran ay kiciso samaynta unugyada cusub ee dareemayaasha, ka dibna walaxda ayaa loo isticmaali karaa si looga hortago loona daweeyo cudurrada neurodegenerative - tani waa gabagabada saynisyahano kala duwan, kuwaas oo daraasaddooda aan hoos ku soo bandhigno.
EGCG oo laga helo shaaha cagaaran ee xusuusta wanaagsan
Daraasadda aan kor ku soo sheegnay, Professor Yun Bai oo ka tirsan Jaamacadda Caafimaadka Milatariga ee Saddexaad ee Shiinaha ee Chongqing, tusaale ahaan, wuxuu muujiyay in EGCG laga bilaabo shaaha cagaaran ay dhab ahaantii kor u qaadi karto neurogenesis ee hippocampus. Hippocampus waa qayb ka mid ah maskaxda oo mas'uul ka ah xusuusta iyo waxbarashada. Halkaa waa halka macluumaadka laga soo wareejiyo xusuusta gaaban loona wareejiyo xusuusta fog si aadan u iloobin waxaad baratay dhowr maalmood ka dib, taas beddelkeedana aad u xasuusan karto.
Jiirarka helay EGCG-ga shaaha-cagaaran wax badan bay barteen oo waxay sidoo kale lahaayeen xusuusta meel ka wanaagsan marka loo eego kooxda isbarbardhigga ee aan helin EGCG.
Shaaha cagaaran wuxuu ka dhigaa kaydadka Alzheimers mid aan waxyeello lahayn
EGCG ka shaaha cagaaran ma aha oo kaliya kor u sameynta unugyada cusub ee dareemayaasha. Walaxda ayaa sidoo kale ka dhigi karta kaydka borotiinka sunta ah ee cudurka Alzheimers mid aan dhib lahayn - ugu yaraan shaybaarka shaybaarka ee unugyada, sida daraasad la sameeyay 2010 hore loo muujiyay.
Cilmi-baarayaal uu hoggaaminayo Jan Bieschke oo ka tirsan Xarunta Max Delbrück ee Daawada Molecular ee Berlin ayaa daahfuray in kaydadka borotiinka ee Alzheimers iyo Parkinson, kuwaas oo aad ugu suntan unugyada neerfaha una horseeda dhimashadooda, ay ka dhigi karaan kuwo aan waxyeello lahayn maaddooyinka firfircoon ee shaaha cagaaran. .
Haddii aad EGCG siiso unugyo ay saamaysay kaydka sunta ah ka dibna ay lahaayeen dheef-shiid kiimikaad xaddidan, tusaale ahaan aad bay u daciifeen, markaas mahadda EGCG kaydkii waxa loo beddelay kayd aan sun ahayn oo unugyadu hadda si fudud u burburi karaan.
Soosaarka shaaha cagaaran wuxuu kordhiyaa waxqabadka maskaxda
2014, saynisyahano Basel ah oo la shaqeeya Professor Christoph Beglinger iyo Stefan Borgwardt ayaa daabacay natiijooyin cilmi baaris oo xiiso leh joornaalka Psychopharmacology: Waxay ogaadeen in shaaha cagaaran uu hagaajin karo isku xirnaanta maskaxda (xidhiidhka ka dhexeeya unugyada dareemayaasha) iyo sidaas awoodaha garashada.
Ka qaybgalayaasha daraasaddan ayaa ahaa rag mutadawiciin ah oo la siiyay cabitaan fudud oo shaaha cagaaran laga soo saaray ka hor inta aan la waydiinin inay xalliyaan hawlaha u baahan xusuusta shaqada gaar ahaan. Xusuusta shaqadu waxay nuugtaa macluumaadka, waxay kaydisaa wakhti gaaban, waxayna ku xidhaa - haddii loo baahdo - macluumaadka jira ee xusuusta muddada-dheer.
Iyadoo la kaashanayo baarista MRI, cilmi-baarayaashu waxay awoodeen inay muujiyaan in maskaxda raggaas helay shaaha cagaaran ay muujiyeen heer aad u sarreeya oo isku xirnaanta gobollada maskaxda ee shakhsi ahaaneed. Isla mar ahaantaana, ragga shaaha cagaaran waxay awoodeen inay si fiican u xalliyaan hawlaha. Markaa soosaarka shaaha cagaaran wuxuu taageeri karaa xusuusta shaqada. Sida saxda ah guryahani waxay caawin karaan daawaynta cilladaha garashada ee cudurada neurodegenerative sida waallida - sidaas darteed jumlada gunaanadka ee daraasadda kooban.
Isticmaal dhammaan walxaha firfircoon ee shaaha cagaaran!
2017, Beglinger iyo kooxdoodu waxay falanqeeyeen 21 daraasadood oo ku saabsan shaaha cagaaran iyo maskaxda, oo ay ku jiraan 4 tijaabooyin la xakameynayo iyo 12 daraasado isdhaafsi ah. Daraasadaha isdhaafsiga ah, kaqeybgalayaashu waxay helayaan labadaba - walaxda firfircoon ka dibna, ka dib nasasho gaaban, diyaarinta placebo.
Falanqaynta ayaa lagu ogaaday in shaaha cagaaran uu hoos u dhigo calaamadaha dhimirka, sida B. waxay yareyn kartaa walaaca, iyo awoodaha garashada, sida. B.Xusuusta ama awoodda wax-saariddu way hagaagtay oo maskaxdu way shaqeysaa, sida. B. waxay kicin kartaa xusuusta ama xusuusta shaqada. Cilmi-baadhayaashu waxay ku nuuxnuuxsadeen in saameyntan shaaha cagaaran aan loo nisbeyn karin walxo firfircoon oo gaar ah, laakiin ay tahay natiijada maaddooyinka dhowr ah ee shaaha cagaaran oo marka la isku daro saameyn togan leh.
Markaa laguma talinayo inaad qaadato EGCG saafi ah ama kaabsal L-Theanine saafi ah. Waxay macno badan samaynaysaa in la cabbo shaaha cagaaran ee organic ama qaadashada kaabsal shaaha cagaaran oo tayo sare leh.
Falanqaynta kale ee 2018 ayaa sidoo kale timid gunaanadka in shaaha cagaaran ama budada shaaha cagaaran ay taageeri karaan oo ay hagaajin karaan hawlaha garashada si aad u wanaagsan marka loo eego kooxda placebo.
Mar kasta oo shaaha cagaarani bato, waa ay yaraanaysaa halista cudurka Alzheimers
Dib u eegis 2019 ayaa sidoo kale muujisay in inta badan cilmi-baarisyada la heli karo ay heleen xiriir togan oo ka dhexeeya isticmaalka shaaha cagaaran iyo dhacdooyinka cudurrada neerfayaasha, ie in Alzheimers iyo cudurrada la midka ah ay u badan tahay in shaaha cagaaran la cabbo.
Sidaa darteed, haddii aad rabto inaad wax wanaagsan u qabato maskaxdaada, haddii aad rabto inaad ka hortagto cudurrada neurodegenerative, ama xitaa haddii aad horeba u dareemaysay xusuusta ugu horreysa, markaa waxaad ku dari kartaa shaaha cagaaran barnaamijka ka hortagga ama daaweynta.
