Abstract

In energy-dispersive histograms, changes in the relative peak intensities were followed, especially C1 and K, which indicate the maturation of endolymph. The maturation of endolymph in the guinea pig occurs prior to birth. In X-ray histograms, distinct peaks for C1 and K, but also for Na, were observed approximately 20 days before (DBB). The lesser relative peak intensities for C1 and K as compared with mature endolymph indicate an immature endolymph composition at this stage of development. The relative peak intensities of C1 and K increased at approximately the 10-DBB stage and showed similar values as at birth.

摘要

在能量色散直方图中,跟踪相对峰强度的变化,尤其是C1和K的变化,它们表明内淋巴的成熟。豚鼠内淋巴的成熟发生在出生前。在X射线直方图中,在出生前约20天(DBB)观察到C1、K以及Na的明显峰。与成熟内淋巴相比,C1和K的相对峰强度较小,表明在这个发育阶段内淋巴成分不成熟。C1和K的相对峰强度在大约DBB 10天阶段增加,并显示出与出生时相似的值。
