Ihomoni yothando ibangela ulonwabo kwaye yomeleza impilo

Uhlolisiso lwakutshanje lufumanise ukuba i<em>oxytocin, eyaziwa ngokuba “yincindi yothando,” eveliswa yimizimba yethu xa sangana yaye sithandana, inokuphilisa “intliziyo eyaphukileyo,” ngokutsho kwengxelo yeBritish Daily Mail.

Abaphandi kwiYunivesithi yaseMichigan State bafumanisa ukuba "ihomoni yothando" ibonakala inamandla okulungisa iiseli kwintliziyo eyenzakeleyo.

Kwaye xa umntu ehlaselwa sisifo senhliziyo, izihlunu zentliziyo - ezivumela ukuba zivumelane - zifa ngobuninzi. Ziiseli ezikhethekileyo kwaye azikwazi ukuzihlaziya.

Abaphandi bafumanisa ukuba i-oxytocin ivuselela iiseli ze-stem kumqolo wangaphandle wentliziyo, ezifudukela kumqolo ophakathi kwaye zijike zibe ziiseli zemisipha yentliziyo.

Ukuza kuthi ga ngoku, abaphandi baye bavavanya kuphela olu nyango kwiiseli zomntu kunye nezinye iintlobo zeentlanzi kwilabhoratri. Kodwa kuyathenjwa ukuba “ihomoni yothando” ingasetyenziswa ngenye imini ukuphuhlisa unyango lomonakalo wentliziyo.

Kuyaphawuleka ukuba "i-oxytocin" yihomoni eveliswa kwingqondo yabantu kunye nezilwanyana, ngokukodwa kwindawo eyaziwa ngokuba yi-hypothalamus. Yeyona khemikhali iphambili enoxanduva lweemvakalelo zokunqula, ukuncamathela kunye nolonwabo.

Ingqondo ivelisa le hormone xa usondelelana nomzimba, kwaye yile nto yabangela ukuba igama elithi "ihomoni yothando" okanye "ihomoni yokubamba." I-Oxytocin isenokusetyenziswa ukuvuselela okanye ukuphucula ukufinyela ngexesha lokubeleka, kunye nokunciphisa ukopha emva kokubeleka.

"Apha sibonisa ukuba i-oxytocin iyakwazi ukwenza iindlela zokulungiswa kwentliziyo kwiintliziyo ezilimeleyo kwi-zebrafish kunye neeseli zomntu (ezikhule kwi-vitro), ukuvula umnyango kwindlela entsha yobomi," kusho umlobi okhokelayo wokufunda uDkt. Aitor Aguirre, uprofesa oncedisayo wokufunda. Ibhayoloji kwiYunivesithi yaseMichigan State. Unyango olutsha olunokubakho lokuvuselelwa kwentliziyo ebantwini.

Kuzo zombini i-zebrafish kunye neenkcubeko zeeseli zomntu, i-oxytocin yakwazi ukwenza iiseli ze-stem ngaphandle kwentliziyo ukuba zingene nzulu kwi-organ kwaye ziguquke zibe yi-cardiomyocytes, iiseli ze-muscle ezijongene ne-contraction yentliziyo.

Uphando lusekumanqanaba okuqala, kodwa iqela linethemba lokuba iiseli ze-cardiac stem ezifudukayo zinokunceda ngolunye usuku ukunyanga abantu abonakele ngenxa yokuhlaselwa yintliziyo.

Abaphandi baqhube iimvavanyo kwi-zebrafish, kuba inamandla akhethekileyo okubuyisela amalungu omzimba anje ngengqondo, amathambo kunye nolusu.

Yaye i<em>zebrafish inokuphinda ikhule ukuya kutsho kwikota yentliziyo, ngenxa yobuninzi bezihlunu zentliziyo nezinye iiseli ezinokulungiswa ngokutsha.

Abaphandi bafumanisa ukuba kwiintsuku ezintathu zokulimala kwentliziyo, amanqanaba e-oxytocin anyuke ukuya kuthi ga kumaxesha angama-20 kwingqondo.

Kwakhona babonisa ukuba le hormone ibandakanyeka ngokuthe ngqo kwinkqubo yokuchacha kwentliziyo. Okubalulekileyo, i-oxytocin yayinempembelelo efanayo kwizicubu zomntu kwityhubhu yovavanyo.

"Nokuba ukuvuselelwa kwentliziyo kuyingxenye kuphela, izibonelelo zezigulane zinokuba zikhulu," utyhile uDkt Aguirre.

Amanyathelo alandelayo kubaphandi baya kujonga umphumo we-oxytocin kubantu emva kokulimala kwentliziyo.

Ekubeni ihomoni ye-oxytocin eveliswa ngokwemvelo iphila ixesha elifutshane emzimbeni, oku kuthetha ukuba amayeza exesha elide e-oxytocin anokufuneka.

Wenza njani ulonwabo kunye nethamsanqa amaqabane endleleni yakho?
