Quantitative ultrastructural morphometric analysis has been carried out on thin sections
of platelets from two Bernard-Soulier sisters and their parents. Measurements were
made for the major and minor axes, axial ratios, cross-sectional circumference and
cross-sectional area. Platelets were collected either into CPD anticoagulant or directly
into glutaraldehyde. The results confirm that Bemard-Soulier platelets are significantly
larger than normals (p <0.05) in all the parameters mentioned and indicate (I) that
the morphology of platelets from Bernard-Soulier patients is affected by the presence
of anticoagulant, and (II) a more spherocytic configuration is characteristic of Bemard-Soulier
disease both in patients and carriers.
