Abstract
Neurokinin B exists as a member of tachykinin family, which is encoded by Tac3 gene and binds to Tac3R. Several studies have shown that neurokinin B is involved in secretion of gonadotropin releasing hormone and maintenance of reproductive function. No data on the effect of neurokinin B on accessory sex glands is available till date. The current study is designed to determine the dose dependent effects of neurokinin B on seminal vesicles of New Zealand White Rabbits. For experimental procedure, 18 New Zealand white rabbits (Oryctolagus cuniculus) were purchased from National Institute Health, Islamabad Pakistan. Adult laboratory rabbits were administrated with neurokinin B at two different dose concentrations (1 ηg and 1 µg) twice daily for a period of continuous 12 days. The results demonstrated a significant increase in seminal vesicles weight and epithelial cell height at all tested doses (P < 0.05). Marked increase in epithelial folds was readily manifested, however the lumen was irregular. In this study histological and structural alterations in seminal vesicles manifest a progressive effect on seminal vesicles subsequent to subcutaneous twice-daily administration of Neurokinin B for 12 days.
