Huperzine A attenuates cognitive deficits and brain injury in neonatal rats after hypoxia ischemia

Wang, Lai Shuan, Zhou, Jin, Shao, Xiao Mei, Tang, Xi Can·2002·Brain Research

Abstract

The protective effects of huperzine A, a novel acetylcholinesterase inhibitor, on hypoxic-ischemic (HI) brain injury were investigated in neonatal rats. A unilateral HI brain injury was produced by the ligation of left common carotid artery followed by 1 h hypoxia with 7.7% oxygen in 7-day-old rat pups. After 5 weeks, HI brain injury in rat pups resulted in working memory impairments shown by increased escape latency in a water maze and reduced time spent in the target quadrant. The combination of common carotid artery ligation and exposure to a hypoxic environment caused the damage in the striatum, cortex, and hippocampus in the ipsilateral hemisphere, and the neuronal loss in the CA1 region. Huperzine A was administrated daily at the dose of 0.05 or 0.1 mg/kg i.p. for 5 weeks after HI injury. The significant protection against HI injury on behavior and neuropathology was produced by huperzine A at the dose of 0.1 mg/kg. These findings suggest that huperzine A might be beneficial in the treatment of hypoxic-ischemic encephalopathy in neonates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
