[Prolactin e thibela takatso, empa e ka talingoa e le "e putsang"
Hormone e tsejoang ka lebese la 'm'a eona e boetse e matlafatsa kamano pakeng tsa batsoali
Lipatlisiso li fumane karolo ea prolactin, hormone e susumetsang tlhahiso ea lebese ho bo-'mè ba hlokang tlhokomelo, kamanong ea batsoali.
Thuto ena e itšetlehile ka ho hlahlojoa ha li-hormone tsa samunu ho tloha ho tamarine e ka holimo ea k'hothone, e nyenyane e kotsing ea tlhaho ea Colombia. Ba lula lihlopheng tsa malapa a le mong feela moo batsoali ka bobeli ba thusang ho hlokomela bana, ba tšoanang le batho.
Phuputso eo e fumane hore ho na le kamano pakeng tsa maemo a prolactine le ho kopanela liphate le ho hohella batho ba baholo. Le hoja ena e ne e le ea pele bakeng sa prolactin, e kile ea fumanoa bakeng sa oxytocin, hormone e susumetsang ho beleha le ho kopanngoa le mefuta e mengata ea monate.
Mefuta ea prolactin e ne e le e mengata har'a batho ba babeli ba neng ba atisa ho kopanela liphate le ho fokotseha le ho ba tlase ho bo-'mè ba neng ba qetile booki, le hoja bana ba bona ba ne ba lula haufi le bona.
Mongoli oa pele o re: "Bo-ntate ba phathahane haholo ka ho hlokomela bana, mohlomong ba ne ba e-na le nako e nyane ea ho sika le ho buisana le balekane ba bona." Charles Snowdon, moprofesa ea hlahileng oa thuto ea kelello Univesithing ea Wisconsin-Madison. "Ha u sheba bo-mme ba neng ba e-na le li-prolactin tse tlase, ba ne ba sa kopanele liphate hangata le balekane ba bona."
Liphetho, tse ngotsoeng koranteng ea Inthanete PLoS One, e eketsa palo e ntseng e eketseha ea ho tšoana ho teng ho oxytocin le prolactin.
Snowdon o re: "Likarolo tsa boitšoaro tsa prolactin li fumane thuto e nyane ho feta ea oxytocin."
Ka ho hlakisa setšoantšo sa ho etsa li-hormone ka ho ikopanya habeli, thuto e fana ka leseli la li-hormone tsa bohlokoa li bapala boitšoarong bo khotsofatsang bo amanang le ho nyalana ha bona.
Ho sibolloa hoo e ka bang lilemo tse 25 tse fetileng hore oxytocin e bile le karolo ea bohlokoa ho tlamahaneng ka bobeli "e bile tšibollo ea maikutlo ea hore oxytocin e ne e se feela taba ea botsoali, kapa tlamo ea 'm'a le lesea, empa e mabapi le tlamahano ea batho ba babeli pakeng tsa batho ba baholo," ho bolela Snowdon. "Hona joale re ntse re fumana ntho e tšoanang bakeng sa prolactin, e leng hormone e nang le litlamorao tse fapaneng mmeleng."
Ho sibolloa ha lithuto tse ling tsa maemo a phahameng a prolactine har'a banna ba hlokomelang masea (ho batho le litlhapi tse ling) ho etsa hore prolactine e bonahale e le ho baka boitšoaro ba botsoali.
Empa Snowdon o re eena le motlatsi-'moho le eena ke Toni Ziegler oa Wisconsin National Primate Research Centre lumela hore prolactin e ka ba litholoana tsa botsoali ho fapana. "Mohlomong ha e sebetse e le mokhoa oa ho khanna tlhokomelo ea botsoali, empa ke phello, moputso oa tlhokomelo ea botsoali."
Mohopolo oa hore prolactin le oxytocin li ka fana ka meputso li matlafalitsoe ke phuputso ea Sejeremane e fumaneng ho phatloha ha lihormone ka bobeli ha banna le basali ba fihla bothateng ha ba ntse ba ratana. "Sena se ile sa nkhothaletsa hore prolactin, har'a lintho tse ling, e ka sebetsa e le mokhoa oa moputso oa thobalano," ho bolela Snowdon.
Ho na le bopaki bo bong ba hore prolactin e na le karolo lipotolohong tsa moputso, ho bolela Snowdon. "Prolactin e thibela lik'hemik'hale tse tsosang takatso tsamaisong ea rona ea methapo, e fokotsa takatso ea rona."
Thuto eo e seng ea tlhaho e ne e etsoa ka kolone ea tamarin e neng e lula lefapheng la litsebi tsa kelello tsa UW-Madison. Ka 2008, kolone e ne e koetsoe 'me liphoofolo li fetisetsoa libakeng tsa li-zoo, libaka tsa khalalelo le lik'holejeng tse ling.
Ho tseba hore lihormone tse peli li bapala karolo e tšoanang ho tlamahaneng batho ba bong bo fapaneng liphoofolong tse anyesang tse lumellanang le mekhoa e meng ea lihormone le boits'oaro ba botsoali, ho bolela Snowdon. “Ho na le ho kopana ho makatsang pakeng tsa prolactin le oxytocin. Hoa utloahala ho nahana hore lihormone tse tšoanang le libaka tsa boko li kentse letsoho ho laoleng boits'oaro bo bohlokoa ho phela joalo ka botsoali le maqhama a mabeli. Re fumana hore tlamahano e ntle ea banyalani ke selelekela sa tlhokomelo e ntle ea bo-ntate ho batho le litšoene. ”
