Systemic biochemical indexes of sympathetic nerve functionplasma catecholamine concentrations and serum dopamine-beta-hydroxylase activitywere correlated with regional indexesnorepinephrine concentration activities of norepinephrine biosynthetic enzymes in the vas deferensānd with blood pressures and pulse rates of 57 men at the time of vasectomy. Mean plasma catecholamine content was increased 66% and 60% in men with elevated systolic and elevated systolic and diastolic blood pressures, respectively. The norepinephrine concentration, tyrosine hydroxylase activity, and dopa decarboxylase activity in the vas deferens were increased in 12%, 26%, and 17% of the men with elevated blood pressure, respectively. Tyrosine hydroxylase and dopa decarboxylase in the men with elevated systolic blood pressure were increased 41% and 68%, respectively, compared with values in the men with normal blood pressure (P less than 0.05 and P less than 0.02). Individual plasma catecholamine content was related directly to both systolic and mean blood pressure (P less than 0.01) and to activities of vas deferens tyrosine hydroxylases (P less than 0.05) and dopa decarboxylase (P less than 0.01). There was a weak, but not significant, correlation of plasma catecholamine concentration with serum dopamine-beta-hydroxylase activity. Raised plasma catecholamine concentration in men with elevated blood pressure prior to vasectomy was associated with increased neurotransmitter biosynthesis in their vas deferens, which may indicate increased sympathetic nerve tonicity and perhaps be a factor contributing to the blood pressure elevation.

Increased plasma catecholamine concentrations and vas deferens norepinephrine biosynthesis in men with elevated blood pressure.
