RatTBIFluid percussionSprague-Dawleymalen = 18 injured and 13 sham rats for the injury comparison; 6 pe…Intraperitoneal0.6 mg/kg90 min after traumatic brain injury
Model: Lateral fluid percussion injury (FPI) or sham injury in anaesthetised adult rats
Traumatic brain injury reduced cortical inhibition at 90 min compared with sham (p=0.03). Huperzine A enhanced cortical inhibition after both sham injury (p=0.002) and traumatic brain injury (p=0.02), restoring inhibition lost after injury. The median time to maximum huperzine A inhibition was 46.4…

RatSpinal cord injuryCompressionWistar AlbinoMaleIntraperitoneal injectionAdministered after clip compression injury
Model: Spinal cord clip compression injury (moderate static clip compression, 70 g for 60 s, at T7 level)
Huperzine A treatment significantly reduced the number of apoptotic cells (P<0.01) and necrotic cells with more normal appearing neurons compared with untreated trauma groups. BBB scores showed improved locomotor performance in the treated group relative to controls.

RatOtherSprague-DawleyMaleOral0.05 or 0.1 mg/kg body weightGiven daily during the 5 days of hypobaric hypoxia exposure
Model: Simulated hypobaric hypoxia at 6,000 m in an animal decompression chamber for 5 days
Huperzine A at 0.1 mg/kg restored spatial memory, with decreased escape latency and path length and increased platform crossings and quadrant time, and significantly reduced hippocampal oxidative stress and pro-apoptotic protein expression.
