Recombinant Human Erythropoietin Therapy and Autonomic Nervous System

Autonomic nervous system dysregulation in human hypertension.

An increased sympathetic drive combined with decreased parasympathetic inhibition is found in patients with borderline hypertension, who characteristically have rapid heart rates, high cardiac output and relatively normal vascular resistance (hyperkinetic state). In established hypertension, cardiac output is normal, vascular resistance is elevated and signs of increased sympathetic drive are a...

Autonomic Nervous System Testing

A utonomic nervous system testing is used to document diabetic autonomic failure. Diabetic autonomic failure is defined as impaired function of the peripheral autonomic nervous system and can be divided into two categories: 1) autonomic neuropathy, in which there is a structural lesion of the peripheral autonomic neuron and 2) functional autonomic failure, in which no known structural lesion oc...

Autonomic Nervous System Derangements

Despite these findings, mostly in the cardiac, esophageal and colon tissue 5,14,15, no correlation exists between the intensity of neuronal destruction and dilation of the heart or other microscopic indices of myocarditis in the chronic phase14. Histopathologic foci of damaged nervous tissue are found in a diffuse and irregular distribution. Neuronal parasitism, with periganglionitis and degene...
