Experimental Lung Transplantation Related With HIF-1, VEGF, ROS. Assessment of HIF-1alpha, VEGF, and Reactive Oxygen Species After Competitive Blockade of Chetomin for Lung Transplantation in Rats.

Unlabelled: Primary graft failure occurs 15 to 30 % of the time after transplantation. Although there have been improvements in preserving the lungs in good condition, there have not been studies on the regulation of transcription factors.

Methods: We carried out an experimental study involving lung transplantation to indirectly evaluate reactive oxygen species (ROS) production and VEGF expression by competitive blockade of HIF-1alpha with chetomin.

Evaluation of the Chetomin effect on histopathological features in a murine acute spinal cord injury model.

Background: Several research studies have been focused on improving the treatment and prognosis of acute spinal cord injury, as part of this initiative we investigated the use of Chetomin to reduce the inflammatory response in this pathology.

Methods: An experimental, prospective, cross-sectional study was performed using 42 Wistar rats where we analyzed the effect of Chetomin compared to methylprednisolone administered 1 and 8 h after the spinal cord injury in a murine model.

Results: Chetomin administration 8h post-injury decreased IL-6 and VEGF expression; and, and its administration 1h post-injury decreased NF-kB expression.
