Nitric oxide synthase in the enteric nervous system of the guinea-pig: a quantitative description
1994
The distribution and abundance of nitric oxide synthase (NOS)-containing neurons and their terminals in the gastrointestinal tract of the guinea-pig were examined in detail using NADPH diaphorase histochemistry and NOS immunohistochemistry. NOS-containing cell bodies were found in the myenteric plexus throughout the gastrointestinal tract and in the submucous plexus of the stomach, colon and rectum. NOS-containing neurons comprised between 12% (in the duodenum) and 54% (in the esophagus) of total myenteric neurons. In the ileum, NOS neurons represented 19% of total myenteric neurons. Most of the NOS neurons throughout the gastrointestinal tract possessed lamellar dendrites and a single axon…
Atteinte de la Muscularis Mucosae dans les tumeurs urothéliales T1 de vessie : facteur pronostique de progression après immunothérapie par BCG
2012
OBJECTIVES: To study the prognostic impact of muscularis mucosae (MM) invasion for pT1 bladder cancer treated by transurethral resection (TUR) and adjuvant Bacille Calmette-Guerin (BCG) intravesical immunotherapy. METHODS: Sixty-six patients treated by BCG intravesical instillations were substaged into pT1a and pT1b, regarding Muscularis Mucosae invasion. Tumor grade, associated carcinoma in situ (CIS), multifocality, tumoral size up to 3cm, BCG maintenance were noted. With a mean follow-up of 50.5±38 months, we studied recurrence, progression, overall and specific survival. Cox's model method was used for multivariate analysis. RESULTS: Tumor recurrence was observed in 30±7% and 43±10% (P=…
