[EX Q]: Abstract: Four patients with chronic subdural hematomas, all of which resolved spontaneously, were followed from the time of injury to resolution of the chronic subdural hematoma. Periodic computed tomographic (CT) scans showed spontaneous resolution 78, 174, 231, and 326 days after the development of the chronic subdural hematoma, respectively. Features of the CT scans and a possible mechanism of spontaneous resolution are discussed.

[EX Q]: Abstract: Thrombospondin with fibrinogen, fibronectin, and von Willebrand factor binds to platelets stimulated with agonists and support platelet adhesive functions. The receptors for the latter three proteins are associated with membrane glycoprotein GPIIb-IIIa. Thrombasthenic platelets deficient in GPIIb-IIIa have been utilized to examine the role of this membrane protein in the interactions of thrombospondin with platelets. Radioiodinated thrombospondin bound to thrombin-stimulated platelets from normal and thrombasthenic donors with a similar affinity and capacity. As monitored with a monoclonal antibody to thrombospondin, the divalent ion-dependent and -independent pathways for the expression of the endogenous pool of thrombospondin on the surface of thrombin-stimulated platelets from normal and thrombasthenic donors were also qualitatively and quantitatively similar. GPIIb-IIIa or ligands associated with GPIIb-IIIa thus are not essential for the binding of thrombospondin to platelets. Therefore, thrombospondin interacts with unique receptors on platelets.

[EX Q]: Abstract: The effects of atracurium and alcuronium on the evoked mechanical and electromyographic responses of the adductor pollicis were investigated in 30 adult patients. The ulnar nerve was stimulated with trains of four supramaximal pulses of 0.2 ms duration and a frequency of 2 Hz at intervals of 20 s. The mechanical response was measured using a strain gauge force transducer and the evoked compound action potential (ECAP) was recorded simultaneously using a Medelec MS91 electromyography system. Depression of the electromyographic and mechanical responses, caused by atracurium, was similar during onset and antagonism of blockade. During onset of blockade by alcuronium, the mechanical response was depressed to a significantly greater extent compared with the ECAP. This difference was not observed during antagonism with neostigmine. The rates of onset of atracurium and alcuronium were generally similar, but the rate of onset of mechanical fade was greater in the alcuronium group. There was no significant quantitative difference between the rates of antagonism of alcuronium and atracurium when assessed by the mechanical first response ratio. Electromyographic first response and electromyographic and mechanical train-of-four ratios recovered more rapidly in the atracurium group. These findings suggest that the differences between mechanical and electromyographic measurements of neuromuscular blockade are drug-specific and are more pronounced during the onset of blockade than during its antagonism by neostigmine.
