OBJECTIVE: To investigate the development of the enteric nervous system(ENS) in the middle stage(the 4th approximate, equals 6th months) of human embryogenesis. METHODS: A histologic evaluation of the clonic enteric nervous system was done using NADPHd histochemistry, PAP immunohistochemistry, with anti-PGP 9.5 and anti-S-100 protein. RESULTS: During this stage of embryology three things were noted. (1)The nerves in the myenteric layer increased markedly. This was shown by the PGP 9.5 immunoreactive nerves spreading out and the S-100 protein immunoreactive nerves forming a "bamboo basket"pattern. (2)The whole myenteric colon showed nitrigeric nerves paralleling the growth of the myofibers in the circular muscle layer. Nitrigeric perikara were rarely found in the extrinsic submucosal layer.(3) In the whole-mounted preparations reactive nerves formed the complex nerve net in the myenteric layer. CONCLUSION: The middle stage of embryogensis is very important to the development of the colon ENS.

This study is to investigate the effect of ethyl gallate on invasion capabilities and its mechanism of breast cancer MDA-MB-231 cells. Using cell adhesion and transwell assay, separately, the effects of ethyl gallate on the invasion of MDA-MB-231 cells were measured. The Akt-NF-κB signal pathway protein expressions were analyzed with Western blot. Also, the mRNA levels of MMP-9 and MMP-2 were analyzed by RT-PCR. Ethyl gallate inhibited the abilities of motility, adhesion and invasion of breast cancer MDA-MB-231 cells in vitro (P<0.05), inhibited the mRNA levels of MMP-9, MMP-2, phosphorylation of AKt and protein expression of NF-κB. It is concluded that ethyl gallate can inhibit the abilities of invasion of breast cancer in vitro by inhibiting the mRNA levels of MMP-9/MMP-2, phosphorylation of Akt and protein expression of NF-κB.
