Treatment with the GHRH agonist JI-34 prevents IH-induced adverse effects on retention of a hippocampal spatial task in the water maze and the deleterious effects of IH on forced swim test in mice. Administration of the GHRH antagonist MIA-602 adversely affects spatial task retention and forced swim performance in normoxic mice but is not additively deleterious to IH. Mean percentage time in the target quadrant during probe trials after completion of water maze testing in mice treated with either J1-34 (A) and Mice exposed to intermittent hypoxia and treatment with J1-34 (B) Data are mean ± SEM. (*IH-VEH vs. RA-VEH, p <0.05; One-way ANOVA).
