Dynamic study on iliac trabeculae of normal Chinese.

We studied 41 iliac bone blocks taken by biopsies from normal Chinese who were divided into several groups by age. On the schedule of 3-11-3-5 days, double tetracycline labellings were administered before bone biopsies. Ten microns undecalcified sections were made with Reichert-Jung microtome and analyzed with Zeizz MOP-Videoplan by light and fluorescent microscopy. The results showed that bone formation had a peak value at adolescence and the mean wall thickness decreased gradually with age. Bone dynamics fluctuated with age because of endocrinological changes in the intrinsic environment. The data we obtained may be used as a reference for clinical investigation of various metabolic bone disorders.

Histomorphometric changes in iliac trabecular parameter with aging.

Iliac bone specimens of 49 normal Chinese subjects were studied. A series of bone histomorphometric parameters were analysed, including mean trabecular width, trabecular bone volume, mean trabecular plate thickness, mean trabecular plate density and mean trabecular plate spacing. The data suggest that there are close correlations of these parameters with aging. The correlations are very significant between mean trabecular width and trabecular bone volume and mean trabecular plate thickness.
