Effect of 6-hydroxydopamine on neuropeptides in the rat female genitourinary tract.
The occurrence and distribution of neuropeptide Y has been determined in the rat female genitourinary tract by radioimmunoassay and chromatographic analysis. Within the bladder, higher concentrations of neuropeptide Y were found in the trigone (48.8 +/- 5.2 pmol/g) than in the dome (36.0 +/- 2.1 pmol/g). In the genital tract, highest concentrations were identified in the vagina (41.4 +/- 2.1 pmol/g). Treatment of rats with 6-hydroxydopamine resulted in significant depletion of neuropeptide Y concentrations in both parts of the bladder, together with vagina, uterine horn and fallopian tube. No change was observed in the cervix, uterine body and ovary. Concentrations of vasoactive intestinal polypeptide were unaffected by treatment with 6-hydroxydopamine except in the area of the cervix where concentrations rose from 64.1 +/- 5.7 pmol/g to 133.6 +/- 15.1 pmol/g (p less than 0.05). There was a generalised, but statistically insignificant rise in substance P concentrations.
