"I-hormone lothando" ngcono amakhono okuhlalisana kwezinye izingane Autism

Izifundo behlola izingane Autism iphathwa ne oxytocin hormone, ebonisa ukuthi umphumela le nqubo sasikhuthaza, kodwa abanye babo. Lokhu kuye kwasiza ukuba ososayensi ukuqonda ukuthi iyiphi izingane kungenzeka ukuba sizuze kule nqubo.

Kulesi sifundo, abacwaningi ithole ndawana umsebenzi ngendlela emangalisayo ithonya le-placebo, okwathi nakuba nekubaluleka kwalo isayensi, is akukaqondwa ngokugcwele.

Izingxabano phakathi ososayensi

Eminyakeni yamuva nje kuye kwaba nemibuzo eminingi ukuthi ukunikeza autistic izingane oxytocin, eyaziwa ngokuthi i-hormone lothando, noma ithemba, ngoba ikhambi izici ezingezinhle isifo sabo. Imbangela ingxabano kwaba kuthinta kanjani ukuziphatha kwabo. Noma kunjalo, ucwaningo kwenziwe ngaphambili, ayemancane futhi ngokuvamile sobuntu sokuhlalisana ngokuthula.

Imiphumela oxytocin ezinganeni autistic

Karen Parker waseStanford University ukuba baqhubeke nalo msebenzi, ukuze uqale zokukala izinga kokuqala oxytocin zonke ingane owaba nengxenye esifundweni sakhe. Khona-ke abantwana 14 nge Autism kwase baphathwe oxytocin ngesimo isifutho kabili ngosuku amasonto amane, futhi omunye 18 wathola placebo. Iningi izingane futhi wawunokukhubazeka bokusungula.

Kwatholakala ukuthi ziphathwe izidakamizwa esebenzayo izingane, okusho ukuthuthuka isilinganiso amaphuzu 10 luhambisane (yi-owaziwa Scale ukuphendula nomphakathi), ngenkathi isimo izingane abathola i-placebo linyuke ngo 3 amaphuzu.

Kwatholakala kwabazuzisa kakhulu ngayiphi indlela izingane abanale amazinga oxytocin ngaphambi kwesifundo kwaba ephansi. Ngakho, oxytocin amazinga egazini kungaba isici begazi ukuthi kuzovumela ngezazi zesayensi ukuba zibikezele kanjani ingane bayosabela ukwethulwa kule hormone.

Ngasekuqaleni emisebenzini yakhe Parker yabonisa ukuthi, naphezu ezingeni eliphakeme oxytocin emzimbeni nge Autism, izingane eziningi uhlukile kakhulu, kokubili iziguli futhi enempilo. Ngaphezu kwalokho, izingane amazinga aphansi oxytocin, hhayi Autism futhi ngokuvamile thuthuva manifest nomphakathi.

Ngakho-ke, kuthathwa ukuthi ukuqinisekiswa ukuphumelela ukwelashwa nge oxytocin akuxhomekile ngabe ingane uhlushwa Autism, kodwa kusuka amazinga yokuqala i-hormone zemvelo.

placebo umphumela

Lokhu okwatholakala angase abe wusizo ikakhulukazi ekutheni ingane ziphathwe isixazululo oxytocin, kodwa isihloko esisha Parker e "iziNyathelo ye-National Academy of Sciences" iqukethe ezinye nemiphumela emangalisayo.

Wathola ukuthi phakathi izingane owasebenzisa i-placebo, kakhulu iwine kwalabo 'ababenolwazi amazinga aphansi oxytocin ekuqaleni kwesifundo. Ngaphezu kwalokho, umzimba yalezi zingane eseqala ukuveza ngaphezulu "i-hormone lothando" ayo. Ngokusho Parker, it kwandisa amathuba ukuthi ithonya le-placebo ezihlukahlukene izimo ngokungaqondile kungaholela nokwanda ukukhiqizwa oxytocin.

Isidingo ucwaningo olwengeziwe

Manje, abanye ososayensi baqhuba efanayo, kodwa ucwaningo okuningi ebanzi xaxa futhi umsebenzi Parker sibonisa lokho kudingeka sinake. UProfesa Antonio Hardan, onendlu umkhuba emtholampilo izingane Autism, uthi ngeke kusekela umbono kokuphatha izingane oxytocin kuphela ngesisekelo ucwaningo Parker, kodwa uyokwenza kanjalo kwenzeka ukuthi iphrojekthi enkulu izoqinisekisa imiphumela.
