A double-blind, randomized, multicenter study of MP4OX for treatment of perioperative hypotension in patients undergoing primary hip arthroplasty under spinal anesthesia.

Background: MP4OX (oxygenated polyethylene glycol-modified hemoglobin) is a novel oxygen therapeutic agent specifically developed to perfuse and oxygenate tissue at risk for ischemia and hypoxia. In this study, we investigated the ability of MP4OX to treat hypotensive episodes. In addition, the tolerability profile of MP4OX in a large surgical population was established.

Increased cold allodynia following intrathecal N-methyl-D-aspartate in rats with a mononeuropathy.

NMDA receptors are involved in the modulation of neuropathic pain behavior and central sensitization. In vivo, this is mostly demonstrated by the use of specific antagonists such as MK801. Because studies evaluating the direct impact of spinal NMDA in neuropathic pain models are lacking, we performed a series of experiments to study the role of spinal NMDA injection on existing cold allodynia, as a measurement of neuropathic pain behavior in rodents.

The role of interleukin-6 in nociception and pain.

That IL-6 is an interesting target in the study of pain is underscored by its biomolecular properties, its localization after experimental pain, and its modulating effect on pain after administration.
