I-hormone yothando idala injabulo futhi iqinisa impilo

Ucwaningo lwakamuva luthole ukuthi i-oxytocin, eyaziwa ngokuthi “ihomoni yothando”, ekhiqizwa imizimba yethu lapho sangana futhi sithandana, ingakwazi ukwelapha “inhliziyo ephukile,” ngokombiko wephephandaba laseBrithani i-“Daily Mail”.

Futhi abacwaningi baseMichigan State University bathola ukuthi “i-hormone yothando” ibonakala inekhono lokulungisa amangqamuzana enhliziyo ethintekile.

Lapho umuntu ehlaselwa isifo senhliziyo, izicubu zenhliziyo ezimvumela ukuba afinyezeke ziyafa ngobuningi. Amaseli akhethekile kakhulu futhi awakwazi ukuzivuselela.

Abacwaningi bathola ukuthi i-oxytocin ivuselela ama-stem cells ongqimbeni lwangaphandle lwenhliziyo, athuthela engxenyeni ephakathi bese ephenduka ama-cardiomyocytes.

Abacwaningi baye bahlola lokhu kwelashwa kuze kube manje kuphela kumaseli omuntu nakwezinye izinhlobo zezinhlanzi elebhu. Kodwa kuthenjwa ukuthi ngolunye usuku "i-hormone yothando" izosetshenziselwa ukuthuthukisa ukwelashwa kokulimala kwenhliziyo.

I-Oxytocin iyi-hormone ekhiqizwa ebuchosheni babantu nezilwane, ikakhulukazi endaweni eyaziwa ngokuthi i-hypothalamus. Kuyikhemikhali enkulu enesibopho semizwa yokukhonzwa, ukunamathela, kanye nenjabulo.

Ingqondo ikhiqiza le hormone lapho isondelana kakhulu ngokomzimba, futhi yilokhu okuyenze yabizwa ngokuthi “ihomoni yothando” noma “ihomoni yokugona.” I-Oxytocin ingase isetshenziselwe ukuvuselela noma ukuthuthukisa ukufinyela ngesikhathi sokubeletha, kanye nokunciphisa ukopha ngemva kokubeletha.

"Lapha sibonisa ukuthi i-oxytocin iyakwazi ukwenza kusebenze izindlela zokulungisa inhliziyo ezinhliziyweni ezilimele ku-zebrafish kanye (in vitro) namaseli omuntu," kusho umlobi oholayo wocwaningo uDkt Aitor Aguirre, uprofesa ohlangene we-biology e-Michigan State University. Izindlela zokwelapha ezintsha ezingase zibe khona zokuvuselela inhliziyo. kubantu.

Kokubili i-zebrafish kanye namasiko amangqamuzana omuntu, i-oxytocin ikwazile ukubangela ama-stem cells angaphandle kwenhliziyo ukuthi adlulele esithweni futhi aguquke abe ama-cardiomyocyte, amangqamuzana emisipha abangela ukufinyela kwenhliziyo.

Ucwaningo lusezigabeni zalo zokuqala, kodwa ithimba lithemba ukuthi ngolunye usuku amangqamuzana enhliziyo afudukayo angakwazi ukusiza ukwelapha abantu abanomonakalo obangelwa ukuhlaselwa yinhliziyo.

Abacwaningi benze lezi zivivinyo kwi-zebrafish ngoba inekhono eliyingqayizivele lokukhulisa kabusha izingxenye zomzimba ezifana nobuchopho, amathambo nesikhumba.

I-Zebrafish ingakwazi ukukhiqiza kabusha ingxenye yesine yenhliziyo, ngenxa yobuningi bemisipha yenhliziyo namanye amaseli angahlelwa kabusha.

Abacwaningi bathola ukuthi phakathi nezinsuku ezintathu zokulimala kwenhliziyo, amazinga e-oxytocin anda ngokufika izikhathi ezingu-20 ebuchosheni.

Baphinde babonisa ukuthi i-hormone ihileleke ngokuqondile ekuphulukiseni kwenhliziyo. Okubaluleke nakakhulu, i-oxytocin yaba nomthelela ofanayo esicutshini somuntu eshubhu lokuhlola.

"Ngisho noma ukuvuselelwa kwenhliziyo kuyingxenye kuphela, izinzuzo ezigulini zingaba zinkulu," uDkt. Aguirre wembula.

Izinyathelo ezilandelayo zabacwaningi kuzoba ukubheka umphumela we-oxytocin kubantu ngemva kokulimala kwenhliziyo.

Njengoba i-hormone eyenzeka ngokwemvelo i-oxytocin ihlala isikhashana emzimbeni, lokhu kusho ukuthi imithi ye-oxytocin yesikhathi eside ingase idingeke.

Uyenza kanjani abangani benjabulo kanye nenhlanhla endleleni yakho?
