Oral administration of the perilla leaf extract (PLE) to mice inhibits inflammation, allergic response, and tumor necrosis factor-alpha production. We also found that PLE suppressed the tumor necrosis factor-alpha (TNF-alpha) production in vitro. Using the inhibitory activity of TNF-alpha production in vitro as the index for isolation, we searched the active constituents from PLE and isolated l...

Alzheimer disease (AD), the most common cause of dementia, is an irreversible progressive neurodegenerative condition. It is characterized by the salient inflammatory features, microglial activation and increased levels of pro-inflammatory cytokines which contribute to the inflammatory states of the CNS. Accumulating data suggest the key role of inflammation in AD pathogenesis. In a prospective...

[Purpose] The purpose of this study was to investigate whether early hyperbaric oxygen is useful in rats with permanent cerebral ischemia, and whether its mechanism relates to the inhibition of the tumor necrosis factor-alpha-protein kinase C-alpha pathway. [Subjects] Healthy, male Sprague-Dawley rats (N = 108) were the subjects. [Methods] After middle cerebral artery occlusion models were succ...
