| Abstract: | ix cases of fetus in 6-7months gestation age and 6 cases of neonates without gastrointestinal de-formation were studied,their Auerbach neuropleux(NP )and ganglia cells(GA)in the esophagus wereobserved with microscope. The GA and NP in esophageal lower sphineter( EIS ) were more abaduntthan those in the rest part of esophagus and stomach,but there were no difference statistically(P>0.05).The GA and NP in fetus in number were much more than those in neonates , and theGA and NP in fetus were more than those in neonates statistically(P<0.05)in ELS atgreat curvature side. At lesser curvature side GA and NP in esophagus and stomach offetus were more than those of neonates statistically(P<0.05). |
