Vincristine hyperalgesia in the rat: A model of painful vincristine neuropathy in humans
Abstract
To investigate the mechanism of vincristine-induced pain in humans undergoing chemotherapy we have established a model of vincristine-induced hyperalgesia in rat. Vincristine (100 micrograms/kg) was administered daily over a period of two weeks. An acute dose-dependent decrease in mechanical nociceptive threshold and an increased response to non-noxious mechanical stimuli ("hyperalgesia") occurred after the second day of administration. Chronic lowered threshold and increased response to stimuli (determined 24 h after each injection) was first noted during the second week of vincristine administration. Responses gradually returned to baseline during the two weeks following discontinuation of treatment. Vincristine also increased sensitivity to heat stimulation. At a dose that produced hyperalgesia (100 micrograms/kg), vincristine did not cause a significant motor deficit. Peripheral administration of a mu-opioid agonist did not reduce vincristine-induced acute hyperalgesia. Hyperalgesia induced by vincristine in the rat provides a good model for the experimental study of painful peripheral neuropathies in human patients receiving vincristine as a chemotherapeutic agent.

“In rats, 10 daily injections of vincristine (0.02, 0.1, or 0.2 mg/kg, intravenous) with a 2-day drug-free interval after the fifth day, induced hyperalgesia (Aley et al, 1996), and allodynia (Authier et al, 1999).”

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.
