Kodi zotsatira za placebo ndi chiyani?

Ndiye kodi zotsatira za placebo ndi chiyani? Placebo ndi mankhwala omwe amachititsa kuti munthu adziŵe bwino. Kuwonjezera apo, zotsatira za placebo zimatchedwa chodabwitsa cha kusagwiritsidwa ntchito kwa mankhwala, pamene kuchiritsa kwa wodwalayo kukugwirizana ndi chikhulupiriro chake cha kuwonongeka kwa mankhwala. Kodi zotsatira za placebo kwenikweni zimagwira ntchito?
Posachedwapa, asayansi a ku Germany asonyeza kuti "zotsatira za placebo" zimakhudza thupi, lomwe limagwira ntchito pamtunda. Kupeza kumeneku kungathandize kupeza njira zowonjezera zowononga ululu ndi mavuto ena.

Pogwiritsira ntchito matekinoloje amakono, ofufuza adapeza kuti kungoganiza kuti amatha kupweteka, ubongo wathu umagwiritsa ntchito njira zowononga. Izi zikusonyeza momwe mphamvu zathu zamoyo zimakhalira.

"Mpweya wa placebo umakhudza kwambiri dongosolo lathu la mitsempha m'dera la msana wa msana. Zizindikiro izi zimalankhula za mphamvu za mankhwala pogwiritsa ntchito zovutazi, "anatero Falk Aypert, wofufuza kafukufuku wa Hamburg Research Medical Center.

Aypert ndi anzake amagwiritsa ntchito maginito opanga maginito kuti aphunzire zomwe zikuchitika mumtsempha wa msana. Kuyesera kunaphatikizapo amayi 15 omwe ali ndi ululu wamanja. Kafukufukuyu anayerekeza zotsatira za MRI ya odwala pamene anauzidwa kuti akugwiritsa ntchito kirimu komanso pamene-mankhwala osokoneza bongo.

Ndipotu, magetsi onsewa analibe zigawo zomangira thupi, komabe, MRI scan inawonetsa kuti ntchito ya mantha ya odwala inali yochepa kwambiri pamene ankaganiza kuti akulandira mankhwala osokoneza bongo.

Kukhoza kwa mankhwala osokoneza bongo popanda zigawo zomangika kuti zikhale ndi zochiritsira thupi zimakhala zodabwitsa madokotala padziko lonse lapansi.

Monga lamulo, odwala "mankhwala osokoneza bongo" amaperekedwa ngati mankhwala oyesera kapena ngati mankhwala oletsa kuchipatala cha mankhwala atsopano. Ndipo umboni wakuti anthu omwe analandira "placebo" sasiyana kwambiri ndi umboni wa anthu omwe akugwiritsa ntchito mankhwala atsopano poyesedwa, zomwe zimachititsa kuti zikhale zovuta kudziwa momwe ntchito yatsopano imathandizira.

Makamaka amphamvu "placebo effect" amapezeka pochiza machitidwe apakati a mitsempha kapena kuchiza matenda, kupweteka. Mwachikhalidwe, akatswiri amawona zotsatira izi ngati zochitika zamaganizo, koma kafukufuku waposachedwapa awonetsa kuti pali chiyambi cha thupi.

Koma chikhalirebe chinsinsi, nchiani chomwe chimayambitsa zotsatira zotere mu msana? Aypert akuganiza kuti mankhwala ambiri omwe thupi lathu limapanga, makamaka apioids zachilengedwe, noradrenaline ndi serotonin, akhoza kukhalapo mu njirayi.

M'nkhani ina m'nyuzipepala ya Science, Aypert ndi anzake adanena kuti ntchito yawo imatsegula mipata yatsopano yopanga mankhwala opweteka osiyanasiyana, kuphatikizapo kupweteka kosatha komanso kuvutika kwa nthawi ndi nthawi kwa amayi.
