Comparison of total nerve fiber density and sympathetic nerve fiber density in peritoneal endometriotic specimens and healthy peritoneum.

(A) Total nerve fibers were positively stained by Anti-PGP 9.5 antibody. Comparison of the total nerve fiber density (NFD, NF/mm2) of endometriosis-associated nerve of peritoneal endometriosis (EAN-PEM), NFD of para-endometriotic nerve of peritoneal endometriosis (PEN-PEM) and NFD of nerve of peritoneum of control (N-PC). (B) Sympathetic nerve fibers were positively stained by Anti-TH antibody. Comparison of endometriosis-associated sympathetic NFD of peritoneal endometriosis (ESAN-PEM), para-endometriotic sympathetic NFD of peritoneal endometriosis (PESN-PEM) and sympathetic NFD of peritoneum of control (SN-PC). *P<0.05.
