Two pools of seven brains each from adult Swiss-Webster mice were homogenized, and supernatants were collected for bioassay. PC-12 cells were placed in a bioassay plate at time zero, at a concentration of 10(4) cells per well, and primed for 48 hours in a medium containing 50 ng/ml of mNGF. The PC-12 cell bioassay for neurite outgrowth was conducted after(More)
The functional role of metabotropic glutamate receptors is beginning to be understood. Cognitive effects of metabotropic receptor activation were examined in the present study in a Morris water maze following intraventricular (i.c.v.) infusions of ACPD(1S,3R). I.c.v. infusions of ACPD substantially increased the amount of time animals took to find a hidden(More)
Calcium-activated proteolysis mediated by the protease inhibitor, calpain, has recently been implicated in the pathogenesis of cerebral vasospasm. The effect of one inhibitor of calcium-activated proteolysis, z-Leu-Phe-CONH-morpholene (zLF), on cerebrovascular constriction was examined in two experimental paradigms. In the first paradigm, the rabbit basilar(More)
RATIONALE  Choroidal neovascular (CNV) lesions in younger patients are often accompanied by the appearance of a surrounding ring of pigment that is associated with disease regression or slowed disease progression. In older patients with age-related macular degeneration (AMD), however, hypertrophy of the retinal pigment epithelium (RPE) is known to occur but(More)
