TL;DR: The results of this investigation suggest that traumatically induced axonal injury involves complex subsets of pathobiology, one evoking rapid primary neurofilamentous change and misalignment, the other eliciting altered membrane permeability concomitant with rapid neurofilaments compaction, leading to a delayed progression of reactive axonal change.
Abstract: Recent studies have suggested that severe forms of traumatic brain injury (TBI) can be associated with direct alterations of the axolemma. The present study evaluated whether injuries of mild to moderate severity are associated with comparable change. To this end, we used extracellular horseradish peroxidase (HRP) to determine if altered axolemmal permeability occurred following the traumatic event. Adult cats received intrathecal infusions of peroxidase and then were prepared for mild to moderate fluid percussion injury. At intervals ranging from 5 min to 3 h, animals were perfused with aldehydes and prepared for the histochemical visualization of the peroxidase, in addition to the immunocytochemical visualization of the neurofilament 68 kD subunit, a long recognized marker of reactive axonal change. The histochemically and immunocytochemically prepared tissue was examined at both the light and electron microscopic level. With mild TBI, the injured animals displayed a repertoire of neurofilament...

TL;DR: The goal was to reach agreements on recommendations and definitions that could facilitate trial design, and simultaneously be tested by research groups pooling their data, to achieve better uniformity in clinical trials.

TL;DR: Immunoblot analyses of liver microsomes isolated from eight patients found that HLp is a human representative of the multigene family of the glucocorticoid-inducible cytochromes P-450, a rat liver cytochrome that is inducible by the anti-glucocortics, by pregnenolone-16 alpha-carbonitrile-inducer, and by such macrolide antibiotics as triacetyloleandomycin
Abstract: It has not yet been determined whether human liver contains inducible cytochromes P-450 similar to those that catalyze the oxidative metabolism of foreign substances in animals. We carried out immunoblot analyses of liver microsomes isolated from eight patients and found that each contained a cytochrome P-450, termed HLp, that reacted with antibodies directed against P-450p, a rat liver cytochrome that is inducible by the anti-glucocorticoid pregnenolone-16 alpha-carbonitrile, by glucocorticoids, by anti-seizure drugs, and by such macrolide antibiotics as triacetyloleandomycin. In the two patients who received dexamethasone and anti-seizure medications and in the one patient who was given triacetyloleandomycin, the concentrations of immunoreactive HLp and the ability to demethylate erythromycin and/or to convert triacetyloleandomycin to a metabolite that forms a spectral complex with cytochrome P-450 heme (catalytic properties unique to P-450p in rat liver) were significantly higher as compared to the values for patients who received no inducing drugs. We purified HLp to homogeneity and found that it was immunochemically related to P-450p and to its homologue in the rabbit (LM3c), actively demethylated erythromycin in a reconstituted system, exhibited electrophoretic mobility identical to that of P-450p, and shared 57% homology in its NH2-terminal amino acid sequence with that of a pregnenolone-16 alpha-carbonitrile-inducible rat cytochrome P-450. We conclude that HLp is a human representative of the multigene family of the glucocorticoid-inducible cytochromes P-450.
