Alcohol exposure during development leads to significant long-term neurobehavior dysfunction and central nervous system alteration. The purpose of this study was to determine the effects of enriched enviroment in developmental period through motor behavior test and expression of BDNF. Neonatal rat exposed to alcohol on postnatal days 4 through 10 were studied. Female Sprague-Dawley pups were assigned to two groups. Experimental group(EG) via 4.5 g kg-1day-1 of ethanol was housed in enriched enviornment for 9 weeks. The main result of this study were as follows: 1. There was significant difference in the mean of weight change between control and experimental group. 2. In motor behavior test, there was significant difference in the mean of weight change between control and experimental group. 3. Regarding the immunoreactivity of BDNF were higher appeared experimental group than control group. In conclusion, the present results reveals that enriched enviroment in developmental period is to be extremely useful in neuronal reprganization and motor behavior improvement after alcohol exposure.
