    Notes: Abstract We investigated the mechanisms of stress-induced alterations in adrenocorticotrophin (ACTH) release. Tandem parachutists received either a placebo or the β-adrenoceptor antagonist propranolol prior to a first time parachute jump. Blood samples were drawn 4 h before, immediately after, and 1 h after the jump. Cortisol and catecholamine concentrations displayed a significant stress-induced increase in both groups. The ACTH plasma concentrations significantly increased in the placebo and the propranolol group, with significantly more pronounced changes in the propranolol-treated subjects compared to the placebo group. These data demonstrated a stress-induced increase of ACTH plasma concentrations in humans that was enhanced by β-blockade.

    Biomechanical analyses of some instrumentations for stabilisation of dorso-lumbar spinal injuries (1983)
    Springer
    Medical & biological engineering & computing 21 (1983), S. 494-502 
    Details
    ISSN: 1741-0444
    Keywords: Biomechanics ; Fixation device ; Spinal fracture

    Notes: Abstract Quantitative biomechanical analyses of approaches for the reduction and fixation of lumbardorsal injury are presented in this paper, entailing (i) classification of the types of injuries, (ii) analysis of the critical functional levels of forces exerted on the injured spinal structures and the stabilisation devices and (iii) the basis for the various modalities of injury reduction stabilisation modes, and for the use of conventional posteriorly attached compression or distraction devices, as well as anteriorly placed vertebral stabilisation-fixation device.
