Application of magnetic resonance diffusion anisotropy imaging for the assessment neuroprotecting effects of MPEP, a selective mGluR5 antagonist, on the rat spinal cord injury in vivo.
Journal Title: Pharmacological Reports - Year 2005, Vol 57, Issue 6
Abstract
Magnetic resonance diffusion anisotropy imaging (DAI) of the rat spinal cord after contusion using weight-drop method was used to study the neuroprotecting effect of 2-methyl-6-(phenylethynyl)-pyridine (MPEP), an mGluR5 receptor antagonist. Eighteen rats were used, divided into 3 groups of 6 animals: a reference group without any operation, a control group with injury and a test group with injury and MPEP. DAI was performed at 4.7 T at 1 h, 24 h, 48 h and 7 day after the injury. Locomotor function was evaluated using Basso, Beattie and Bresnahan (BBB) open field locomotor activity test each day starting one day after the injury. DAI results confirm positive effect of MPEP on the limitation of secondary excitotoxic injury in the spinal cord.
