BBB scores, residual urine volume and bladder weight as well as characteristic cystometric parameters at 6th week were used to confirm the successful establishment of NB.

CX43 and phospho\u2010CX43 protein levels were significantly decreased, but those of TGF\u2010\u03b21, Smad3, and phospho\u2010Smad3 were significantly increased. It was the protein and mRNA levels of CX43 but not those of CX45 which were decreased in negative accordance with those of TGF\u2010\u03b21 and Smad3.
