Cardiovascular and vasopressin (AVP) responses to hemorrhage were studied in rats with lesions of the hypothalamic supraoptic nuclei (SONL). Bleeding caused hypotension and increase in heart rate (HR) and AVP. SONL rats failed to fully recover from bleeding as compared to normal rats. Plasma AVP in SONL rats was in the normal in basal conditions, but failed to increase to levels attained in normal rats throughout the post-hemorrhage period. These data suggest that the supraoptic nuclei are the… CONTINUE READING
