Hyperemic Response

Cessation of perivascular nerve stimulation (NS) elicits a transient increase in intestinal blood flow above the prestimulatory value. This enhancement of blood flow constitutes the phenomenon of post-nerve stimulation hyperemia (PSH). We investigated the involvement of peptidergic sensory nerves in intestinal PSH. In anesthetized rats the velocity of blood flowing through the anterior mesenteric artery (VBF) was measured with a pulsed Doppler velocimeter. PSH was induced by 4 min of postganglionic electrical NS (5 Hz). PSH was abolished by distal periarterial application of tetrodotoxin and intra-arterial lidocaine, which suggests a peripheral sensory nervous mechanism for PSH. The increase in conductance at peak PSH was blocked by pretreatment with the selective, primary afferent neurotoxin capsaicin administered as 1) subcutaneous injection in neonatal life, 2) topical application to periarterial nerves, or 3) injection into the jejunal lumen. In rats pretreated with reserpine, NS evoked a hyperemic response, which was blocked by capsaicin. Treatment with adenosine deaminase inhibited PSH considerably less than capsaicin, suggesting a lesser role for adenosine in PSH. Our findings support the hypothesis that postganglionic NS activates both adrenergic and peptidergic nerves and that the latter release vasodilator peptides in the gut during PSH.

And Function

Serotonin immunoreactive neuroendocrine cells and peptidergic nerves (NPY and VIP) could have a role in prostate growth and function. In the present study, rats grouped by stages of postnatal development (prepubertal, pubertal, young and aged adults) were employed in order to ascertain whether age causes changes in the number of serotoninergic neuroendocrine cells and the length of NPY and VIP fibres. Discriminant analysis was performed in order to ascertain the classificatory power of stereologic variables (absolute and relative measurements of cell number and fibre length) on age groups. The following conclusions were drawn: a) discriminant analysis confirms the androgen-dependence of both neuroendocrine cells and NPYVIP innervation during the postnatal development of the rat prostate; b) periglandular innervation has more relevance than interglandular innervation in classifying the rats in age groups; and c) peptidergic nerves from ventral, ampullar and periductal regions were more age-dependent than nerves from the dorso-lateral region.
