Abstract

BACKGROUND: Cistanche tubulosa (Schenk) R. Wight (CT) is commonly used to treat forgetfulness by traditional Chinese physicians. This study presents the ameliorating effects of CT extract which was quantified with three phenylpropanoid glycosides in Alzheimer's disease (AD)-like rat model. METHODS: Amyloid β peptide 1-42 (Aβ 1-42) intracisternally infused to rats by osmotic pump (Alzet 2002) was used as an AD-like rat model. The major pathological makers were measured including Aβ 1-42 immunohistochemical stain, behavioral tests (inhibitory avoidance task and Morris water maze) and central neurotransmitter functions. RESULTS: Aβ 1-42 caused the cognitive deficits, the increase in the amyloid deposition and acetylcholinesterase activities, and the decrease in the levels of brain's acetylcholine and dopamine. Daily administration of CT extract throughout Aβ 1-42 infusion periods ameliorated the cognitive deficits, decreased amyloid deposition and reversed cholinergic and hippocampal dopaminergic dysfunction caused by Aβ 1-42. Donepezil also ameliorated the cognitive dysfunction, but only blocked the amyloid deposition and cholinergic dysfunction caused by Aβ 1-42. CONCLUSIONS: We suggest that CT extract, containing enough echinacoside and acteoside, ameliorated the cognitive dysfunction caused by Aβ 1-42 via blocking amyloid deposition, reversing cholinergic and hippocampal dopaminergic neuronal function.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Cistanche tubulosa aqueous extract (100-200 mg/kg) improved cognitive function, reduced amyloid deposition, and reversed cholinergic and dopaminergic dysfunction, with 200 mg/kg significantly decreasing cortical AChE activity in amyloid beta-infused rats.

    “Cistanche tubulosa aqueous extract (100–200 mg/kg) improved cognitive function, reduced amyloid deposition, and reversed cholinergic and dopaminergic dysfunction, with the 200 mg/kg dose significantly decreasing cortical AChE activity in Aβ-infused rats [80].”

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.
