Morphological and functional aspects of neurosecretory process in hypothalamic nuclei in heart failure

Abstract

Hypothalamus studied in 18 men who died from injuries, acute coronary insufficiency and congestive heart failure. In the supraoptic (SOY) and paraventricular (PVN) nuclei determined percentage neurocyte that are in various phases of neurosecretory cycle. Calculated the index of the functional activity of the nuclei. Revealed an uneven change in the ratio neurocyte that are in various phases of neurosecretion and index decreased functional activity of SOY in various forms of heart failure. The index of the functional activity of the PVN in acute coronary insufficiency remains on the "control" value. The observed changes are regarded as a morphological indicator of the regulatory function of the hypothalamus.
