Ի՞նչ ազդեցություն ունի վիտամին A-ն հղիների վրա
PHOTO
Ամերիկացի գիտնականները, որոնք ուսումնասիրել են հղի մկներին, ապա նաեւ նրանց ձագերին, հղիության ժամանակ վիտամին A-ի ընդունումը ապագա երեխային կպաշտպանի վարակներից, երբ նա կմեծանա եւ դառնա հասուն մարդ:
Հետազոտության արդյունքում պարզվել է, որ այն մկների մոտ, որոնց մայրերը վիտամին A չեն ստացել, ավշային համակարգը, որն ապահովում է իմունային արձագանքը, ավելի վատ է զարգացել:
Դրա արդյունքում այդպիսի մկներն ավելի հաճախ են վարակիչ հիվանդություններով հիվանդացել: Գիտնականները պնդում են, որ իրենց հայտնաբերած օրինաչափությունը բնորոշ է նաեւ մարդկանց:
