* College of Dentistry, King Saud University, P.O.Box 60169, Riyadh 11454, Saudi Arabia, ** School of Dental Medicine, University of Connecticut, Farmington, CT 06032, USA. Human periodontal ligament fibroblasts and L 929 cell line labelled with chromium 51 were examined byelectron microscope to evaluate the effect of the chromium labeling on the cell ultrastructure. The cells were labeled with chromium 12-20 hours before the start of the experiment. After two and four hours of incubation at 37°C and 100% humidity, the cells were examined by scanning and transmission electron microscopy. The result showed that the chromium labeling did not cause any morphological changes. Saudi Dental Journal 1990;2(3):101-106. |
