The effects of electroacupuncture on analgesia and peripheral sensory thresholds in patients with burn scar pain.

The aim of this study is to observe if the effects of electro-acupuncture (EA) on analgesia and peripheral sensory thresholds are transposable from the model of heat pain in volunteers to the clinical setting of burn scar pain. After severe burns, pathological burn scars (PPBS) may occur with excruciating pain that respond poorly to treatment and prevent patients from wearing their pressure garments, thereby leading to unesthetic and function-limiting scars. EA might be of greater benefit in terms of analgesia and functional recovery, should it interrupt this vicious circle by counteracting the peripheral hyperalgesia characterizing PPBS.

Quantitative determination of haptoglobin (HAP) in human and bovine sera by capillary zone electrophoresis (CZE).

This study describes an original assay for serum haptoglobin determination by measuring the capacity of human haptoglobin (hHAP) and bovine haptoglobin (bHAP) to bind haemoglobin (Hb) as established by capillary zone electrophoresis (CZE). This method involves the addition of Hb in excess to the serum and the separation of the HAP-Hb complexes from free haemoglobin by CZE. Protein migration was recorded at a wavelength of 415 nm which reveals Hb alone (free or bound), and the concentration of HAP was indirectly estimated by measuring bound Hb.
