The nuclear enzyme poly(ADP-ribose) polymerase (PARP), which has been shown to be activated following experimental traumatic brain injury (TBI), binds to DNA strand breaks and utilizes nicotinamide adenine dinucleotide (NAD) as a substrate. Since consumption of NAD may be deleterious to recovery in the setting of CNS injury, we examined the effect of a(More)
In frontal lobe contusions obtained post mortem from 18 patients who survived between 6 h and 10 days after head injury, DNA fragmentation associated with either apoptotic and/or necrotic cell death was identified by the terminal deoxynucleotidyl transferase-mediated biotinylated deoxyuridine triphosphate nick end labelling (TUNEL) histochemical technique.(More)
A linear relationship exists in the albino rat between the heart weight and the basal metabolic rate when varied by the administration of active thyroid material. It is suggested that this increase in heart weight which follows the increase in metabolism after thyroid is in the nature of a simple work hypertrophy of the myocardium.
