The Morphology of Thrombin-activated Platelets with Reference to Different Fibrinogen Concentrations as Revealed by Computer-aided Three-dimensional Reconstruction.

Washed human platelets incubated in different concentrations of fibrinogen were activated by thrombin and aggregated in the presence of Ca(2+) or did not aggregate when EDTA was present. They were analyzed by transmission electron microscopy and computer-aided three-dimensional reconstruction. The volumes and surface areas of the reconstructed models were calculated.

Function of the glenohumeral ligaments in active stabilisation of the shoulder joint.

Unlabelled: The joint capsules and the glenohumeral ligaments of 12 human shoulder specimens were histologically investigated by light microscopy. Serial sections of 15 microns thickness were cut. The tissue was stained following the haematoxylin-eosin and van Giesson techniques.
