Аналоги фрагмента HLDF как модификаторы устойчивости организма к действию холода

It was shown that the prophylactic administration of synthesized Tyr-analog of a peptide HLDF-6 decreased the response of hypothalamus-hypophysis-adrenal glands system and sympathicoadrenal system of rat males on supercooling. HLDF-6 and its Tyr-analog also increased the resistance (the duration of life) of mouse males to supercooling. In the experiences with females these peptides did not show the similar biological activity.
