RESUMEN

The aim of the present study is to verify the functional and anatomical neural pathways which innervate the urinary bladder in the central nervous system of the rat. To identify the functional neural pathway, the urinary bladder was stimulated by infusing formalin for 2 h. Then, brain and spinal cord were dissected out and immunohistochemistry was done by using anti-c-fos antibody. Many c-fos immunoreactive (IR) neurons were identified in the telencephalic cortical areas and in several brainstem nuclei, which are known mostly to be related with urinary bladder. In the spinal cord, a number of c-fos IR neurons were found in the lamina I, IIo, dorsal gray commissure, sacral parasympathetic nucleus. To identify the anatomical neural pathway of the urinary bladder, Pseudorabies virus (PRV) was injected into the wall of urinary bladder and was identified with anti-PRV by using immunohistochemistry. Most PRV labeled neurons were found where c-fos IR neurons were identified and few of them were also in the areas where c-fos IR neurons were not found, e.g., prefrontal cortex, agranular insular cortex, and subfornical organ. In the spinal cord, PRV labeled cells were found all over the gray matter. The present study presents morphological evidence demonstrating the supraspinal areas are related with the neural control of the urinary bladder and most functional neural pathway of the urinary bladder is well consistent with the anatomical neural pathway except in some telencephalic cortical areas.

RESUMEN

In order to elucidate the existence and locality of DARP in the human brain, immunohistochemical identification was done in the brain tissues. This glycoprotein was distributed in paraventricular nucleus and thalamic reticular nucleus of diencephalon, substantia nigra and inferior colliculus of mesencephalon, medial vestibular nucleus, medial longitudinal nucleus, lateral reticular nucleus of medulla oblongata. And they follows a close distribution to that of catecholamine (CA) rich in either CA fiber or CA neuronal cell groups as previously reported by others using tyrosine hydroxylase (TH) as a marker. This striking similarities in the topographic arrangement of the DARP-positive reaction product and the TH-positive reaction product is another argument favoring the view that DARP is involved in the regulation of catecholaminergic neurons.
