Method: Wistar rats at the age of two month,half male and half female, were divided into three groups randomly: normal iodine group (NI group), 10 and 50 folds of normal iodine intake group (10HI and 50HI groups). After fed with different concentration iodine diet for 24 weeks, the morphology change of the hippocampal astrocytes i
