title: [Genetic correlation between the arterial pressure response during emotional stress and the alpha1-adrenoreceptor concentration in brain regions].
abstract: Arterial blood pressure reactivity to the emotional stress and brain alpha 1-adrenoreceptors concentrations were studied in hypertensive (ISIAH strain) and normotensive (Wistar strain) rats and their F1 and F2 hybrids. Significant correlations between the stress-induced increase in the arterial blood pressure and the amount of alpha 1-adrenoreceptors in hypothalamus (+0.46) and medulla (+0.38) were found in the F2. This cosegregation may point to the significant role of genetically determined peculiarities of expression of alpha 1-adrenoreceptors in brain regions during pathogenesis of arterial hypertension in the ISIAH strain.
