Abstract:

A series of six progressively severe abrupt acceleration tests was conducted on seven human sled subjects in the forward-facing position, with the final two impacts on each subject being -20Gx peak, at an onset rate of 800 Gsec. Thrombocyte counts made before, 1 hour after and 24 hours after impact revealed a one-hour post-impact decrease of major proportion, with full recovery to mean pre-impact thrombocyte concentrations by 24 hours post-impact. An elevation of pre-impact baseline thrombocyte counts occurred after the first and fith tests. Various mechanisms for this effect are presented, and areas of potential use are outlined. Author
