Alkyl nitrites have been problematic worldwide due to their recreational use. Although there is a lack of scientific information on their action on the central nervous system (CNS), many anecdotal reports and case studies have inferred the CNS actions of alkyl nitrites. The objective of this study was to investigate the effects of alkyl nitrites on the CNS, especially focusing on the dopaminerg...

introduction: the role of different parts of the extended amygdala in metabolic signs of stress is not well understood. in the present study, we decided to evaluate the impact of the shell part of nucleus accumbens (nac) on metabolic disturbance induced by electro foot shock stress using transient inactivation method in the rat.  methods: male wistar rats (w: 230-250 g) were canuulated unilater...

BACKGROUND AND PURPOSE We sought to investigate cerebral mechanisms underlying locomotor recovery after stroke. METHODS We measured cortical activities during hemiparetic gait on the treadmill before and after 2 months of inpatient rehabilitation in 8 patients with initial stroke (5 men, 3 women; 4 with right and 4 with left hemiparesis; aged 57 years; 3 months after stroke on average), using...

Background: Stem cells have created hope for treatment of obstinate cases as injured spinal cord (ISC).Objective: aims to assess possible early therapeutic effect bone marrow mesenchymal stem (BM-MSCs) on regeneration ISC and estimate effective transplantation routes in animal models. Material Methods: 62 adult male albino rats were used; two BM-MSCs extraction 60 allocated into three groups. C...

Stimulation in the hypothalamus elicits locomotor stepping. Before stepping is initiated, head scanning movements occur. We determined the relationships between the latency of locomotor initiation and the number, extent and direction of the head scanning movements. Chronic stimulation electrodes were stereotaxically implanted in and around the hypothalamus of 29 rats. Under awake conditions, 38...

Spinal cord injury (SCI) is one of the most severe traumatic injuries that results in dysfunction of limbs and trunk below the damaged section. Recent studies have shown that gastrodin (GAS) could improve the recovery of SCI. In the current study, we aimed to examine the possible mechanism underlying the effect of GAS on recovery of SCI in rats. In rats with SCI, GAS improved locomotor function...

Bone marrow stromal cell (BMSC) transplantation has been reported as treatments that promote functional recovery after spinal cord injury (SCI) in humans and animals. Polyethylene glycol (PEG) has been also reported as treatments that promote functional recovery after spinal cord injury (SCI) in humans and animals. Therefore, administration of PEG combined with BMSC transplantation may improve ...
