Muva nje, ososayensi baseJalimane baye bafakazela ukuthi "umphumela we-placebo" unomphumela wangempela emzimbeni, osebenza ngokuqondile emgodini. Lokhu kutholakala kungasiza ekutholeni izindlela eziphumelelayo zokuqeda ubuhlungu nezinye izinkinga.
Esebenzisa ubuchwepheshe bamuva, abacwaningi bathola ukuthi ukukholelwa nje ekukhipheni ubuhlungu, ubuchopho bethu buvula izinqubo ezihloswe ngazo ukuqeda. Lokhu kubonisa ukuthi amandla ethu okuphilayo ayenamandla kangakanani.
"Umphumela we-placebo unomthelela omkhulu kakhulu ohlelweni lwethu lwezinzwa endaweni yomgogodla. Lezi zikhombisi zikhuluma ngamandla ezidakamizwa ezisekelwe ekusetshenzisweni kwalesi simo, "kusho uFalk Aypert, umcwaningi oholayo ku-Hamburg Research Medical Center.
U-Aypert nabalingani bakhe basebenzise imifanekiso yokusekela i-magnetic resonance ukuze bafunde izinqubo ezenzeka emthonjeni womgogodla. Lo mzamo wawubandakanya abesifazane abangu-15 abanezinhlungu. Ucwaningo lwaqhathanisa imiphumela ye-MRI yeziguli lapho betshelwa ukuthi basebenzisa ukhilimu kuphela futhi uma-isisindo somuthi wokubulala umzimba.
Eqinisweni, izikhwama zombili azizange ziqukathe izingxenye ezisebenzayo, noma kunjalo, isisindo se-MRI sibonise ukuthi umsebenzi wezinzwa wabagulane wanciphisa kakhulu lapho becabanga ukuthi bathola ukuhlinzekwa komzimba.
Ikhono lemithi yokukhohlisa ngaphandle kwezingxenye ezisebenzayo ukuze kube nomthelela wokwelapha emzimbeni sekuye kwaphazamisa odokotela emhlabeni wonke isikhathi eside.
Njengomthetho, iziguli "imithi yokwelapha" inikezwa njengomuthi wokuhlola noma njengesidakamizwa sokulawula ekuvivinyweni kwemitholampilo yemithi emisha. Futhi iqiniso lokuthi ubufakazi babantu abathola i-placebo "abufani kakhulu nobufakazi babantu abathatha izidakamizwa ezintsha ngaphansi kokuhlolwa, okwenza kube nzima ukuthola ukusebenza komuthi omusha.
Umthelela omkhulu "we-placebo effect" uvela ekwelapheni kwesistimu yezinzwa zomphakathi noma ekwelapheni ukucindezeleka, ubuhlungu. Ngokwesiko, ochwepheshe babheka lokhu kube yinto yokucabanga kwengqondo, kodwa ucwaningo lwamuva lubonise ukuthi kukhona isizinda somzimba.
Kodwa kusekhona imfihlakalo, yini ngempela eyenza umphumela onjalo emgodleni? U-Aypert ukholelwa ukuthi amakhemikhali amaningana omzimba wethu akhiqizayo, ikakhulukazi i-apioids yemvelo, i-noradrenaline ne-serotonin, ingaba khona kule nqubo.
Kulo magazini e-Science, Aypert nabasebenza naye bathi umsebenzi wabo uvula amathuba amasha okuthuthukisa imithi ngokumelene nezinhlobonhlobo zobuhlungu, kuhlanganise nobuhlungu obungapheli kanye nobuhlungu besikhathi esisodwa kubafazi.
