The purpose of this study was to measure the changes in levels of nerve growth factor (NGF) in dorsal root ganglia (DRG) and spinal nerves with the aim of investigating the role of NGF in a rat neuropathic pain model. Nerve injuries were made by tight ligation of the left L5 and L6 spinal nerves using 6–0 silk thread in male Sprague-Dawley rats. Before(More)
Forskolin was used to study cyclic AMP-mediated regulation of aqueous humor dynamics in rabbits. Crystalline forskolin was solubilized in oil and its pharmacological effects were studied both in vitro and following topical ocular administration. In vitro, using cultured corneal epithelial cells, forskolin rapidly stimulated cyclic AMP production and in vivo(More)
In periodontal diseases, inflammatory mediators , including interleukin (IL)-6, IL-8 and tumor necrosis factor-α (TNF-α), may promote the degeneration of inflamed periodontal tissues. In previous studies, levels of these three cytokines were demonstrated to be elevated in inflammatory gingival tissues and gingival crevicular fluid. The aim of the present(More)
Wide-field specular microscopy, fluorophotometry, pachymetry, and scanning electron microscopy are used to characterize a reproducible, in vivo model of corneal endothelial injury and recovery in the rabbit. Following an 8-mm central cryo-injury, the cornea remains thickened for as long as 3 weeks. Mean endothelial permeability to fluorescein is above(More)
The intracellular pathway by which beta-adrenergic agonists and antagonists affect aqueous humor dynamics involves the intracellular mediator, cyclic AMP. We have therefore tested the activity of forskolin, a direct activator of adenylate cyclase, in rabbits. Following a 15 min in vitro incubation in the presence of forskolin (15 microM) and(More)
