We recently demonstrated that aged mice are less likely to survive following traumatic injury and are more immunosuppressed than young mice who sustain comparable injuries. Immunosuppression in severely injured patients and in rodent models of burn injury is associated with a marked elevation in proinflammatory cytokines, including interleukin-6 (IL-6). We… (More)
Bone marrow stromal cells are potent providers of stimuli that induce proliferation of B-cell precursors. We proposed that stromal cells play a role in protecting B-lineage cells from corticosteroid-induced apoptosis. We found that stromal cells protected B-cell precursors from dexamethasone-induced apoptosis, but this did not strictly correlate with… (More)
One explanation for the deterioration of the humoral immune response in elderly individuals is that B lymphopoiesis declines with increasing age. Recent studies report a dramatic decline in pre-B cell numbers in old mice. Surprisingly, the number of mature B cells does not decline with age. To determine if new B cells are made in aged animals despite the… (More)
The effect of acute IP ethanol injections on the extracellular aspartate, glutamate, taurine and GABA content of the basolateral amygdala microdialysate was investigated in relationship with total brain ethanol. Each acute intraperitoneal injection of ethanol, 0.5, 1.0, 2.0 and 3.0 g/kg body weight, induced an immediate increase in microdialysate taurine;… (More)

Adenylate cyclase activity in rat striatum decreased post mortem. Half-lives were about 2.7 h at 22 degrees C, 72 h at 4 degrees C. Differences in stability after death of adenylate cyclase in human brain and rat striatum, and possible heterogenity of the enzyme, are briefly discussed.
