Abstract:
Objective To study the innervation between baldder and rectum.Methods The retrograde fluorescent double labeling method was used.Propidium Iodide(PI)was injected into the right wall of the rectum of male SD rats and Bisbenzimide(Bb)into their right wall of urinary bladder.Results The fluorescent double labeled neurons were found in the right L6-S3 and L1-L3 dorsal root ganglia(DRG).Conclusion DRG cells at L6-S3 and L1-L3 simultaneously innervate the rectum and the urinary bladder,explaining that the abnormal micturition due to chronic constipation may be caused by axis reflex at the level of the peripheral process of DRG cells.
