After traumatic spinal cord injury (SCI), there is an opportunity for preserving function by attenuating secondary cell loss. Astrocytes play crucial roles in the adult CNS and are responsible for the vast majority of glutamate buffering, potentially preventing excitotoxic loss of neurons and oligodendrocytes. We examined spatial and temporal changes in(More)
Several procedures were utilized to study the effects of prolactin on dopamine synthesis in the medial basal hypothalamus of the rat. Elevation of serum prolactin was produced by the administration of trifluoperazine (5 mg/kg, i.p.) and resulted in a significant increase in the conversion of [3',5'-3H]tyrosine to dopamine when measured in slices of medial(More)
OBJECT Using cellular transplants to treat spinal cord injury is a promising therapeutic strategy, but transplants grafted directly into the injury site can further damage the already compromised cord. To avoid additional trauma and to simplify translation to the clinic, it is advantageous to use less invasive delivery methods. METHODS The authors(More)
Muscular dysgenic (mdg/mdg) myotubes cultured alone do not contract. Glucosephosphate isomerase (GPI-1) isozymes were analyzed to determine the final genotype of cultured dysgenic (mdg/mdg, gpi-1a/a) myotubes to which normal embryonic spinal cord and limb cells (CBA/J +/+, gpi-1b/b) had been added. Although both myoblast and spinal cord cell additions(More)
The effect of six dopamine agonists including apomorphine, epinine, dopamine, piribedil, lergotrile and bromocriptine on the incorporation of [3H]tyrosine into dopamine was studied in slices and synaptosomes prepared from various brain areas containing dopamine terminals including striatum, nucleus accumbens, olfactory tubercle and medial basal(More)
