The present investigations has been carried out in order to get a base for quantitative recording of nuclear size changes of guinea pig cochlear sensory cells which are be found after noise exposure. The nuclei of normal cochlear hair cells differ in size. Inner hair cell nuclei are rapidly increasing in size at the first third of the basal turn and reach a maximum at the transition to the second turn. Up to the cochlear apex they are decreasing in size until they have reached the size of the lower basal turn again. Outer hair cell nuclei are clearly smaller than inner hair cell nuclei in the first three turns. From basal to apical outer hair cell nuclei show an almost linear increasing in size and at the end of the fourth turn they are nearly comparable with those of inner hair cells. There are no significant differences in nuclear size between the three rows of outer hair cells in the first and second turn. In the third turn however an increase of size of outer hair cell nuclei from medial ot lateral could be found.
进行本研究是为了获得豚鼠耳蜗感觉细胞核大小变化定量记录的基础，这些变化在噪声暴露后可以被发现。正常耳蜗毛细胞的细胞核大小不同。内毛细胞核在基底转的前三分之一处迅速增大，并在向第二转过渡时达到最大值。直至耳蜗顶端，其大小逐渐减小，直到再次达到基底转下部的大小。在前三个转中，外毛细胞核明显小于内毛细胞核。从基底到顶端，外毛细胞核大小几乎呈线性增加，在第四转结束时，它们几乎与内毛细胞核相当。在第一转和第二转中，三排外毛细胞的细胞核大小没有显著差异。然而，在第三转中，可以发现外毛细胞核大小从内侧到外侧有所增加。
