Because chronic vincristine (VCR) treatment causes neuropathic pain, as demonstrated by mechanical allodynia, effective therapeutic strategy is required. In this study, we investigated a suppressive effect of imipramine (IMI) on VCR-induced mechanical allodynia in mice. VCR (0.1 mg/kg, intraperitoneally (i.p.)) was administered once per day for 7 d in ICR male mice. Mechanical allodynia was eva...

In the present study, we investigated whether dynamic and static allodynia would be developed in the affected dermatome in murine models of herpetic pain and postherpetic neuralgia and pharmacologically characterized the allodynia. Inoculation with herpes simplex virus type-1 on the femur induced skin lesions in the dermatome including the plantar region of the hind paw from day 5 to day 21 aft...

Most of the anaesthesia related neurological complications are associated with paresthesia upon introduction spinal needle. Steroids may shorten duration effects caused by nerve injury. A 27-year-old female patient undergoing caesarean section experienced during intrathecal After wore off, she developed tactile allodynia. Intravenous hydrocortisone was given; marked improvement pain and allodyn...

introduction: glial activation and secretion of cytokines at the spinal level is known as part of chronic pain pathogenesis. although changes in tnfα at the supraspinal level are reported during chronic pain, its exact role and site of action remain to be elucidated. we investigated the effect of microinfusion of tnfα into the lc in a rat model of neuropathic pain. methods: male wistar rats wer...

We investigated using the mice role of nitric oxide synthase (NOS) in the spinal dorsal horn in herpetic and postherpetic pain, especially allodynia, which was induced by transdermal inoculation of the hind paw with herpes simplex virus type-1 (HSV-1). The virus inoculation induced NOS2 expression in the lumbar dorsal horn of mice with herpetic allodynia, but not postherpetic allodynia. There w...

IntroductionMigraine is a primary headache disorder with generalized neuronal hyperexcitability. Migraine individuals have high prevalence of cutaneous allodynia, neck pain, and reduced cervical isometric strength. Lower strength also known to correlate greater severity allodynia. However, the correlation between muscle endurance allodynia not yet known. ObjectiveTo evaluate in migraine women. ...

Load during mastication is an important factor for the development and maintenance of mechano- receptor properties. The purpose of this study was to examine property changes in the rat TMJ mechano-receptors under conditions of liquid diet feeding and low articular load during the growth period. The hypothesis was that alterations in mastication of liquid diet might increase TMJ mechano-receptor...

Cold allodynia, pain in response to cooling, occurs during or within hours of oxaliplatin infusion and is thought to arise from a direct effect of oxaliplatin on peripheral sensory neurons. To characterize the pathophysiological mechanisms underlying acute oxaliplatin-induced cold allodynia, we established a new intraplantar oxaliplatin mouse model that rapidly developed long-lasting cold allod...
