We investigated the functional recovery of motoneurons after reimplanting an avulsed ventral root in a rat model of traction injury. The eighth cervical root (C8) was avulsed by controlled traction and immediately reimplanted to the spinal cord. Spinal nerves from neighbouring segments (C5, C6, C7 and T1) were ligated and cut. After 12 or 20 weeks, the(More)
BACKGROUND The pathogenic role of brain derived neurotrophic factor (BDNF) in the incisional pain is poorly understood. The present study explores the role of the BDNF in the incision-induced pain hypersensitivity. METHODS A longitudinal incision was made in one plantar hind paw of isoflurane-anesthetized rats. Dorsal root ganglias (DRG) and spinal cords(More)
We have established that extensive reinnervation and functional recovery follow immediate reimplantation of avulsed ventral roots in adult rats. In the present study, we examined the consequences of reimplantation delayed for 2 weeks after avulsion of the C6 spinal root. Twelve and 20 weeks after delayed reimplantation, 57% and 53% of the motoneurons in the(More)
In visceral pain, anxiety and pain occur simultaneously, but the etiogenesis of this effect is not yet well-described. The anterior cingulate cortex (ACC) is known to be associated with the affective response to noxious stimuli. The aim of the current study is to define the role of ACC extracellular signal-regulated (ERK)-1 and-2 (ERK1/2) activity in the(More)
Depression is a common psychiatric disorder associated with chronic stress. Insulin-like growth factor 2 (IGF2) is a growth factor that serves important roles in the brain during development and at adulthood. Here, the role of IGF2 expression in the hippocampus was investigated in a rat model of depression. A chronic restraint stress (CRS) model of(More)
In spite of the fact that brain derived neurotrophic factor (BDNF) has been reported to be implicated in the development of visceral pain, it remains to be determined whether the role of BDNF in pain is gender dependent. The present study investigated the effect of BDNF on visceral pain in different gender rats. A model for visceral pain was established by(More)
Opioid addiction is a major social, economic, and medical problem worldwide. Long-term adverse consequences of chronic opiate exposure not only involve the individuals themselves but also their offspring. Adolescent maternal morphine exposure results in behavior and morphologic changes in the brain of their adult offspring. However, few studies investigate(More)
Previous studies have indicated involvement of the mitogen-activated protein kinase (MAPK) pathway in heterosexual interactions among rats. Very few studies, however, have focused its role in isosexual social interactions. We studied the male rat's isosexual social interactional behavior using (i) the three-chambered social interaction box and (ii)(More)
Clinical studies on cancer patients have revealed that chemotherapy is associated with long-term cognitive impairment. In the present study, we used a rat model to evaluate the effects of the anticancer drug cytosine arabinoside (Ara-C) on spatial learning, memory, and the dendritic morphology of neurons in the anterior cingulate cortex (ACC) and(More)
Neuropathic pain evoked by nerve injury is frequently accompanied by deterioration of emotional behaviors, but the underlying signaling mechanisms remain elusive. Glutamate (Glu) is the major mediator of excitatory synaptic transmission throughout the brain, and abnormal activity of the glutamatergic system has been implicated in the pathophysiology of pain(More)
