  • Sprague-Dawley 70-90 g were administered with 100 ⁇ L of 2% carrageenin by intraplantar injection into the right hind paw. Animals were dosed with the test drug after development of peak hyperalgesia. Separate groups of animals were used for the mechanical and thermal hyperalgesia studies.
  • Nociceptive pressure thresholds were measured in the rat paw pressure test using an analgesimeter (Ugo Basile). A cut-off point of 250 g was used to prevent any damage to the paw. The intraplantar injection of carrageenin produced a reduction in the nociceptive pressure threshold between 3 and 5 hours after injection, indicating induction of hyperalgesia. Morphine (3 mg/kg, s.c.) produced a complete blockade of hyperalgesia ( Figure 2). Gabapentin (3-300 mg/kg, s.c.) and CI-1008 (1-100 mg/kg, s.c.) dose-dependently antagonized the hyperalgesia, with respective MED of 10 and 3 mg/kg ( Figure 2). B. Thermal Hyperalgesia
  • the assay of Bennett G.J. provides an animal model of a peripheral mononeuropathy in rat that produces disorder of pain sensation like those seen in man (Pain. 1988;33:87-107).
  • mice Male Sprague-Dawley rats (250-300 g), obtained from Bantin and Kingmen, (Hull, U.K.) were used in all experiments. Before surgery, animals were housed in groups of 6 under a 12-hour light/dark cycle (lights on at 07 hour 00 minute) with food and water ad libitum. Postoperatively, animals were housed in pairs on "Aqua-sorb" bedding consisting of air laid cellulose (Beta Medical and Scientific, Sale, U.K.) under the same conditions. All experiments were carried out by an observer blind to drug treatments.
  • Animals were anaesthetized with 2% isofluorane and 1.4 O 2 /NO 2 mixture which was maintained during surgery via a nose cone.
  • the plantar surface of the right hind paw was prepared with 50% ethanol, and a 1-cm longitudinal incision was made through skin and fascia, starting 0.5 cm from the edge of the heel and extending towards the toes.
  • the plantaris muscle was elevated using forceps and incised longitudinally.
  • the wound was closed using two simple sutures of braided silk with a FST-02 needle.
  • the wound site was covered with Terramycin spray and Auromycin powder. Postoperatively, none of the animals displayed any signs of infection with the wounds healing well after 24 hours. The sutures were removed after 48 hours.
  • Tactile allodynia was measured using Semmes-Weinstein von Frey hairs (Stoelting, Illinois, U.S.A.). Animals were placed into wire-mesh-bottom cages allowing access to the underside of their paws. The animals were habituated to this environment prior to the start of the experiment. Tactile allodynia was tested by touching the plantar surface of the animals hind paw with von Frey hairs in ascending order of force (0.7, 1.2, 1.5, 2, 3.6, 5.5, 8.5, 11.8, 15.1, and 29 g) until a paw withdrawal response was elicited. Each von Frey hair was applied to the paw for 6 seconds, or until a response occurred.
  • morphine (6 mg, s.c.) increased PWL of the contralateral paw in the thermal hyperalgesia test (data not shown).
  • the results presented here show that incision of the rat plantaris muscle induces thermal hyperalgesia and tactile allodynia lasting at least 3 days.
  • the major findings of the present study are that gabapentin and S-(+)-3-isobutylgaba are equally effective at blocking both nociceptive responses.
  • morphine was found to be more effective against thermal hyperalgesia than tactile allodynia.
  • S-(+)-3-isobutylgaba completely blocked induction and maintenance of allodynia and hyperalgesia.
