Abstract:

the toxicity effects of corn silk on neurobehavior of Wistar rats,including learning,memory and nervous excitation was studied Test system including autonomic activities,Morris water maze,and darkness avoiding were chosen to measure the rats fed with different levels of corn silk for 77 days.Autonomic activities test shows that times of autonomic activities for male animals are higher than that of female nimals,however,there were no significantly difference between groups.Morris water maze test shows that the average swimming distance of female test animals are obviously lower than the ocontrol group,the average swimming speed of high does group in male animals significanly higher than the other groups.Darkness avoiding test shows that corn silk has no side effect on the Wistar rats,in some way,it can promote the ability of memory,but it is does independent.It can be concluded that corn silk has no side effect on neurobehavior of Wistar rats with does up to 8.0%,which corresponds to a mean daily corn silk intake of approximately 9.354 and 10.308 g/kg body weight for males and females,respectively,on the contrary,corn silk can promote the ability of memory.
