Nthawi zambiri timamva mawu oti "moyo wokhala chete" m'malo olakwika, amanenedwa kuti ndi chifukwa cha thanzi labwino kapena ngakhale kuyamba kwa matenda. Koma kodi nchifukwa ninji moyo wongokhala uli wovulaza kwenikweni? Posachedwapa ndinapeza nkhani yomwe inandifotokozera zambiri.
Zimadziwika kuti kuchita masewera olimbitsa thupi kumatha kukhudza kwambiri ubongo, kulimbikitsa mapangidwe a maselo atsopano ndikupangitsa kusintha kwina. Kafukufuku watsopano wapezeka wosonyeza kuti kusasunthika kungayambitsenso kusintha kwa ubongo mwa kusokoneza ma neuroni ena. Ndipo izi zimakhudza osati ubongo, komanso mtima.
Deta yotereyi idapezedwa panthawi ya kafukufuku yemwe adachitika pa makoswe, koma, malinga ndi asayansi, ndizofunikira kwambiri kwa anthu. Zotsatirazi zingathandize kufotokoza, mwa zina, chifukwa chake moyo wongokhala uli woipa kwambiri kwa matupi athu.
Ngati mukufuna kudziwa zambiri za kafukufukuyu, muwapeza m'munsimu, koma kuti musakulemetseni ndi tsatanetsatane, ndikuuzani zomwe zili.
Zotsatira za kuyesaku, zofalitsidwa mu The Journal of Comparative Neurology, zikuwonetsa kuti kusachita masewera olimbitsa thupi kumasokoneza ma neuron mu gawo limodzi laubongo. Gawoli limayang'anira dongosolo lamanjenje lachifundo, lomwe, mwa zina, limayang'anira kuthamanga kwa magazi mwa kusintha kuchuluka kwa mitsempha yamagazi. Pagulu la makoswe oyesera, omwe sanathe kusuntha mwachangu kwa milungu ingapo, nthambi zambiri zatsopano zidawonekera mu ma neuron a gawo ili la ubongo. Zotsatira zake, ma neuron amatha kukwiyitsa dongosolo lamanjenje lachifundo kwambiri, kusokoneza magwiridwe antchito ake ndipo potero kungayambitse kuwonjezeka kwa kuthamanga kwa magazi ndikuthandizira kukulitsa matenda amtima.
Inde, makoswe si anthu, ndipo iyi ndi phunziro laling'ono, lachidule. Koma mfundo imodzi ndi yodziwikiratu: moyo wongokhala uli ndi zotsatirapo zambiri zakuthupi.
Zikuwoneka kwa ine kuti patatha sabata ndikuzizira, zomwe, mwatsoka, sizili zanga konse ndipo zimandilepheretsa kukhala mumpweya wabwino komanso ntchito yanga yonse, ndimamva ngati nditatha kuyesa. Ndipo nditha kuganiza zanga kuchokera pakuyesaku: kusachita masewera olimbitsa thupi kumawononga kwambiri malingaliro ndikukhala bwino wamba. ((
Zambiri pamutuwu:
Mpaka zaka 20 zapitazo, asayansi ambiri ankakhulupirira kuti dongosolo la ubongo limakhala lokhazikika ndi chiyambi cha uchikulire, ndiko kuti, ubongo wanu sungathenso kupanga maselo atsopano, kusintha mawonekedwe a omwe alipo, kapena m'njira ina iliyonse kusintha thupi. mkhalidwe wa ubongo wake pambuyo pa unyamata. Koma m'zaka zaposachedwa, kafukufuku wamanjenje wawonetsa kuti ubongo umasunga pulasitiki, kapena kuthekera kosintha, m'miyoyo yathu yonse. Ndipo, malinga ndi asayansi, kuphunzitsa thupi kumakhala kothandiza kwambiri pa izi.
Komabe, pafupifupi palibe chomwe chimadziwika ngati kusowa kwa masewera olimbitsa thupi kungakhudze kusintha kwa ubongo, ndipo ngati ndi choncho, zotsatira zake zingakhale zotani. Chifukwa chake, kuti achite kafukufukuyu, zambiri zomwe zidasindikizidwa posachedwa mu The Journal of Comparative Neurology, asayansi ochokera ku Wayne State University School of Medicine ndi mabungwe ena adatenga makoswe khumi ndi awiri. Iwo anaika theka la iwo m’makola okhala ndi mawilo ozungulira, mmene nyama zikanakhoza kukweramo nthawi iliyonse. Makoswe amakonda kuthamanga, ndipo amathamanga makilomita pafupifupi atatu patsiku ndi magudumu awo. Makoswe ena anatsekeredwa m’makola opanda mawilo ndipo anakakamizika kukhala ndi moyo wongokhala.
Patatha pafupifupi miyezi itatu yakuyesera, nyamazo zidabayidwa utoto wapadera womwe umadetsa ma neuron muubongo. Choncho, asayansi ankafuna kuyika ma neuroni m'dera la rostral ventromedial la medulla oblongata ya zinyama - gawo losadziwika la ubongo lomwe limayang'anira kupuma ndi zochitika zina zosazindikira zofunika kuti tikhalepo.
Rostral ventromedial medulla oblongata imayendetsa dongosolo lamanjenje lachifundo la thupi, lomwe, mwa zina, limayang'anira kuthamanga kwa magazi mphindi iliyonse posintha kuchuluka kwa vasoconstriction. Ngakhale kuti zambiri zomwe asayansi apeza zokhudzana ndi rostral ventromedial medulla oblongata zachokera ku zinyama zoyesera, kafukufuku wojambula zithunzi mwa anthu amasonyeza kuti tili ndi dera lofanana la ubongo ndipo limagwira ntchito mofananamo.
Dongosolo loyang'aniridwa bwino lachifundo lachifundo limapangitsa kuti mitsempha ya magazi ifalikire kapena kufooketsa, zomwe zimapangitsa kuti magazi aziyenda bwino, kotero mutha kunena kuti, kuthawa wakuba kapena kukwera pampando waofesi popanda kukomoka. Koma kuwonjezereka kwa dongosolo lamanjenje lachifundo likuyambitsa mavuto, malinga ndi Patrick Mueller, pulofesa wothandizira wa physiology ku Wayne University yemwe ankayang'anira kafukufuku watsopano. Malinga ndi iye, zotulukapo zaposachedwapa zasayansi zikusonyeza kuti “manjenje ochita zinthu mopitirira muyeso amathandizira ku matenda a mtima ndi mitsempha yamagazi mwa kuchititsa kuti mitsempha ya magazi ikhale yolimba kwambiri, yofooka kwambiri kapena kawirikawiri, zomwe zimayambitsa kuthamanga kwa magazi ndi kuwonongeka kwa mtima.
Asayansi amalingalira kuti dongosolo lamanjenje lachifundo limayamba kuchitapo kanthu molakwika komanso mowopsa ngati lilandira mauthenga ochulukirapo (mwina opotoka) kuchokera ku ma neuroni mu rostral ventrolateral medulla oblongata.
Chotsatira chake, pamene asayansi anayang’ana mkati mwa ubongo wa makoswe awo nyamazo zitakhala zikugwira ntchito kapena zongokhala kwa milungu 12, anapeza kusiyana kwakukulu pakati pa magulu aŵiriwo m’kapangidwe ka ma neuron ena a m’chigawo chimenecho cha ubongo.
Pogwiritsa ntchito pulogalamu ya digito yopangidwa ndi makompyuta kuti apangitsenso mkati mwa ubongo wa nyama, asayansi adapeza kuti ma neuron muubongo wa makoswe othamanga anali ofanana ndi momwe amachitira poyambira phunziroli ndipo amagwira ntchito bwino. Koma mu ma neuron ambiri muubongo wa makoswe osakhazikika, antennae ambiri atsopano, otchedwa nthambi, adawonekera. Nthambizi zimagwirizanitsa ma neuroni athanzi mu dongosolo lamanjenje. Koma ma neuron awa tsopano anali ndi nthambi zambiri kuposa ma neuron wamba, zomwe zimawapangitsa kukhala okhudzidwa kwambiri ndi zokondoweza komanso sachedwa kutumiza mauthenga mwachisawawa ku dongosolo lamanjenje.
M'malo mwake, ma neuron awa asintha m'njira yoti amakwiyitsa kwambiri dongosolo lamanjenje lachifundo, zomwe zitha kuyambitsa kuthamanga kwa magazi ndikupangitsa kuti pakhale matenda amtima.
Kupeza kumeneku ndikofunikira, akutero Dr. Müller, chifukwa kumakulitsa kumvetsetsa kwathu momwe, pamlingo wa ma cell, kusagwira ntchito kumawonjezera chiopsezo cha matenda amtima. Koma chochititsa chidwi kwambiri ndi zotsatira za maphunzirowa ndikuti kusasunthika - monga ntchito - kungasinthe mapangidwe ndi ntchito za ubongo.
