title: Neuropeptide Y and somatostatin immunoreactive perikarya in preaortic ganglia projecting to the rat ovary.
abstract: Postganglionic perikarya in preaortic ganglia projecting to the ovary of the rat were identified utilizing the retrograde fluorescent tracer, true blue. Ovarian perikarya were subsequently examined for neuropeptide Y and somatostatin immunoreactivity. True blue-labelled ovarian postganglionic perikarya were distributed in the coeliac ganglion and in smaller ganglia located at the origins of the renal and ovarian arteries. In the coeliac ganglia, 74.4 +/- 18.8% of true blue-labelled ovarian perikarya were immunoreactive to neuropeptide Y while 37.4 +/- 9.6% were immunoreactive to somatostatin. In the inferior smaller ganglia, 72.2 +/- 18.7% and 2.2 +/- 2.2% of the true blue-labelled ovarian perikarya were immunoreactive to neuropeptide Y and somatostatin respectively. It is suggested that neuropeptide Y and somatostatin participate in the modulation of ovarian function.
