Left sciatic nerves in rats were crushed and allowed to regenerate for variable periods of time up to 14 days; uncrushed right nerves from the same animals were used as controls. Two days before killing the rats, both L-5 dorsal root ganglia (DRG) were injected with 100 microcuries [3H]glucosamine. Gangliosides were purified separately from sciatic nerve(More)
Left sciatic nerves of adult male Sprague-Dawley rats were crushed and allowed to recover for 0, 1, 2, 4, 7, or 14 days. At each of these times both L-5 dorsal root ganglia were injected with 100 microCi of [3H]glucosamine. Two days later, dorsal root ganglia, lumbosacral trunks, and sciatic nerves were removed bilaterally. The amounts of radiolabelled(More)
l-Cycloserine can inhibit the synthesis of some sphingolipids, which may play a role in determining membrane fluidity. To evaluate the effects of l-cycloserine on neural cell membranes, adult mice were treated with 100 mg/kg of this drug twice daily for 1, 2, 4, 6, 13 and 17 days. Body weights in the treated mice decreased significantly. Cholesterol and(More)
Marked changes in ganglioside composition occur during brain development and in cultured neurons concomitant with differentiation, and maximum ganglioside synthesis occurs during neuronal maturation and synaptogenesis. These findings indicate that gangliosides probably play an important role in brain development. In this study the effects of parenterally(More)
Chlorpromazine (CPZ) binding and the binding to isolated guinea pig superior cervical of a toxic metabolite 7,8-dihydroxychlorpromazine (7,8-diOH-CPZ) were studied under resting and potassium-stimulated conditions. Maximal binding occurred more rapidly in high potassium, with binding of CPZ 10 fold higher than that of 7,8-diOH-CPZ. However, in low potassium(More)
