Homoni yachikondi imabweretsa chisangalalo ndikulimbitsa thanzi

Kafukufuku waposachedwapa wapeza kuti oxytocin, yotchedwa "hormone ya chikondi", yomwe matupi athu amatulutsa tikakumbatirana ndi kugwa m'chikondi, amatha kuchiza "mtima wosweka," malinga ndi lipoti la nyuzipepala ya ku Britain ya Daily Mail.

Ndipo ofufuza a pa yunivesite ya Michigan State anapeza kuti “hormone ya chikondi” imaonekanso kuti ili ndi mphamvu yokonzanso maselo a mu mtima wokhudzidwa.

Munthu akadwala matenda a mtima, minofu ya mu mtima imene imamuthandiza kugunda imafa kwambiri. Ndi maselo apadera kwambiri ndipo sangathe kudzikonzanso okha.

Ofufuzawa adapeza kuti oxytocin imayambitsa maselo amtundu wakunja kwa mtima, omwe amasamukira kumtunda wapakati ndikusintha kukhala cardiomyocytes.

Ofufuzawa ayesa mankhwalawa mpaka pano kokha m'maselo aumunthu ndi mitundu ina ya nsomba mu labu. Koma tikuyembekeza kuti tsiku lina "hormone yachikondi" idzagwiritsidwa ntchito kupanga chithandizo cha kuvulala kwa mtima.

Oxytocin ndi timadzi timene timapangidwa mu ubongo wa anthu ndi nyama, makamaka kudera lotchedwa hypothalamus. Ndi mankhwala aakulu omwe amachititsa kuti munthu azikondedwa, azikondana komanso azisangalala.

Ubongo umatulutsa timadzi tating'onoting'ono tomwe timagwirana kwambiri, ndipo izi ndi zomwe zidapangitsa kuti atchulidwe kuti "hormone yachikondi" kapena "hormone yokumbatira." Oxytocin angagwiritsidwenso ntchito kulimbikitsa kapena kuchepetsa kukomoka panthawi yobereka, komanso kuchepetsa kutuluka kwa magazi pambuyo pobereka.

"Pano tikuwonetsa kuti oxytocin imatha kuyambitsa njira zokonzetsera mtima m'mitima yovulala mu zebrafish ndi (in vitro) maselo aumunthu," anatero Dr Aitor Aguirre, pulofesa wothandizira wa biology ku Michigan State University. mwa anthu.

M'magulu onse a zebrafish ndi maselo aumunthu, oxytocin inatha kuchititsa kuti maselo a tsinde kunja kwa mtima asunthire mozama mu chiwalo ndikusintha kukhala cardiomyocytes, maselo a minofu omwe amachititsa kuti mtima ukhale wolimba.

Kafukufuku akadali m'mayambiriro ake, koma gulu likuyembekeza kuti tsiku lina maselo amtundu wa mtima omwe amasamuka adzatha kuthandizira anthu omwe akuwonongeka chifukwa cha matenda a mtima.

Ofufuzawa adachita mayeso pa zebrafish chifukwa ili ndi luso lapadera lokulitsanso ziwalo zathupi monga ubongo, mafupa ndi khungu.

Zebrafish imatha kusinthika mpaka gawo limodzi mwa magawo anayi a mtima, chifukwa cha kuchuluka kwa minofu yamtima ndi maselo ena omwe amatha kukonzedwanso.

Ofufuzawo adapeza kuti mkati mwa masiku atatu atavulala pamtima, kuchuluka kwa oxytocin kumawonjezeka mpaka 20 muubongo.

Anasonyezanso kuti hormone imakhudzidwa mwachindunji ndi kuchira kwa mtima. Chofunika kwambiri, oxytocin anali ndi zotsatira zofanana pa minofu ya munthu mu chubu choyesera.

"Ngakhale kusinthika kwa mtima kumakhala kochepa chabe, ubwino kwa odwala ukhoza kukhala waukulu," adatero Dr. Aguirre.

Masitepe otsatirawa a ochita kafukufuku adzakhala kuyang'ana zotsatira za oxytocin pa anthu pambuyo pa kuvulala kwa mtima.

Popeza kuti timadzi timene timatulutsa timadzi ta oxytocin sikhala nthawi yayitali m'thupi, izi zikutanthauza kuti mankhwala a nthawi yayitali a oxytocin angafunike.

Kodi mumapanga bwanji abwenzi achimwemwe ndi mwayi panjira yanu?
