Methods The otoconia of 18 guinea pigs were damaged by a high G force (10 Gy 5 min), and their utricle macula were observed by scanning electron microscopy at 1 h, 2 d and 8 d after the damage respectively. The elements of different kinds of otoconia were measured qualitatively and quantitatively by electron probe Xray microanalysis.
