This study was conducted to make a new mouse model of neuropathic pain due to injury to a branch of the sciatic nerve. One of three branches (sural, tibial, and common peroneal nerves) of the sciatic nerve was tightly ligated, and mechanical and cool stimuli were applied to the medial part (tibial and common peroneal nerve territories) of the plantar skin.(More)
Location and axonal projection of interneurons presumed to mediate disynaptic inhibition evoked from the trigeminal sensory nerve in the ipsi- and contralateral masseter motoneurons were studied in pentobarbital anesthetized cats. Neurons monosynaptically excited from the periphery and antidromically activated from the contralateral trigeminal motor nucleus(More)
Peripheral postischemic dysesthesia was examined behaviorally in mice and we investigated the underlying molecular mechanism with a focus on oxidative stress. Hind-paw ischemia was induced by tight compression of the ankle with a rubber band, and reperfusion was achieved by cutting the rubber tourniquet. We found that reperfusion after ischemia markedly(More)
Transient ischemia-reperfusion in the hand and foot elicits spontaneous dysesthesia. However, the mechanisms by which this occurs are not completely understood. The objectives of this study were to examine peripheral neural activity related to spontaneous dysesthesia in a mouse model of hind-paw transient ischemic-reperfusion and to investigate the(More)
BACKGROUND Postherpetic neuralgia (PHN) is a common complication of herpes zoster and remains a challenging condition of neuropathic pain. Allodynia, a prominent feature of PHN, extends beyond the margins of the initial rash area. In the present study, we investigated the association between cutaneous denervation and the development of postherpetic(More)
