Letsatsi: 04 July 2011
Ho thata ho ja chip e le 'ngoe ea litapole,' me thuto e ncha e ka hlalosa hore na hobaneng.
Lijo tse mafura tse kang li-chips le fries li hlohlelletsa 'mele ho hlahisa lik'hemik'hale tse ts'oanang le tse fumanoang matekoane, bafuputsi ba tlaleha kajeno (Phupu 4) koranteng ea Proceedings of the National Academy of Sciences (PNAS). Lik'hemik'hale tsena, tse bitsoang "endocannabinoids," ke karolo ea potoloho e u bolokang u khutlela ho loma e le 'ngoe feela ea chisi ea chisi, thuto e fumane.
"Ena ke pontšo ea pele ea hore ho tšoaetsoa ha endocannabinoid ka maleng ho bapala karolo ea bohlokoa ho laoleng ho ja mafura," ho etsa lipatlisiso mofuputsi Daniele Piomelli, moprofesa oa thuto ea meriana Univesithing ea California, Irvine, o boletse polelong.
Lik'hemik'hale tsa matekoane tsa ka tlung
Phuputso e fumane hore mafura a ka mpeng a baka ho lokolloa ha li-endocannabinoids bokong, empa lintho tse bohlooho lipakeng tsa litsebe tsa hau ha se setho feela se etsang likhemik'hale tsa tlhaho tse kang matekoane. Letlalo la motho le lona le etsa lintho. Letlalo li-cannabinoids li ka bapala karolo e tšoanang ho rona joalo ka ha li etsa limela tsa pitsa: Ts'ireletso ea mafura moeeng le letsatsing.
Endocannabinoids e boetse e tsejoa ho susumetsa takatso ea lijo le mohopolo oa tatso, ho latela phuputso ea 2009 ho PNAS, e hlalosang li-munchi tseo batho ba li fumanang ha ba tsuba matekoane.
Thutong e ncha, Piomelli le basebetsi-mmoho le eena ba ile ba kenya likhoto tse nang le li -hubhu tse neng li tla hlakola se ka mpeng ea bona ha ba ja kapa ba e-noa. Methapo ena ea ka mpeng e ile ea lumella bafuputsi hore ba bolele hore na mafura a sebetsa lelemeng, maemong ao ba tla bona
endocannabinoid e lokolloa esita le ka li-tubes tse kentsoeng, kapa ka maleng, moo ba neng ba ke ke ba bona phello.
Likhoto li ile tsa fokotseha ka ho sisinyeha ha bophelo bo botle (vanilla Ensure), tharollo ea tsoekere, mokelikeli o nang le protheine e ngata o bitsoang peptone, kapa seno se nang le mafura a mangata se entsoeng ka oli ea poone. Joale bafuputsi ba ile ba tsebisa litoeba bona ba ba ba li hlobolisa, 'me ka potlako ba imolla litho tsa bona ka potlako.
Bakeng sa lerato la mafura
Ho leka tsoekere le liprotheine ha hoa ka ha ama ho lokolloa ha lik'hemik'hale tsa tlhaho tsa matekoane 'meleng, bafuputsi ba fumane. Empa ho fana ka mafura ho entse joalo. Liphetho li bonts'itse hore mafura a lelemeng a baka leqhubu bokong, ebe le fetisetsa molaetsa ho ea maling ka mokotlana oa methapo o bitsoang vagus nerve. Molaetsa ona o laela tlhahiso ea li-endocannabinoids ka maleng, e leng se tla etsa hore ho be le matšoao a mang a sutumetsang molaetsa o ts'oanang: Ja, ja, ja!
Molaetsa ona o ka be o thusitse nalaneng ea phetoho ea liphoofolo tse anyesang, ho boletse Piomelli. Mafura a bohlokoa bakeng sa ho phela, 'me ho ne ho le thata ho fihla lijong tsa liphoofolo tsa matsoalloa. Empa lefatšeng la kajeno, moo lebenkele le bonolo le tletseng lijo tse se nang phepo le lutseng hukung e ngoe le e ngoe, lerato la rona la ho iphetola ha lintho la mafura le khutlela morao habonolo.
Se fumanoeng se fana ka maikutlo a hore ka ho thibela ho amoheloa ha matšoao a endocannabinoid, bafuputsi ba tsa bongaka ba ka khona ho senya mokokotlo o khannelang batho ho ja lijo tse mafura haholo. Ho thibela li-receptor tsa endocannabinoid bokong ho ka baka ts'oenyeho le khatello ea maikutlo, Piomelli o itse, empa sethethefatsi se etselitsoeng ho hlasela mpa se ka 'na sa se ke sa baka litlamorao.
