Stark wirksam bei geringen Nebenwirkungen: In der Anästhesie dienen Muskelrelaxantien zum Einstellen guter Intubationsbedingungen über eine tiefe neuromuskuläre Blockade; am häufigsten wird hierfür Rocuroniumbromid verwendet. Die hierdurch hervorgerufene neuromuskuläre Blockade wird durch die Bildung eines fest gebundenen, binären Komplexes (Ka≈ 107 M−1) zwischen dem Gastmolekül Rocuroniumbromid und einer synthetischen Wirtverbindung auf Cyclodextrinbasis (siehe Struktur im Kristall) aufgehoben. Im Hinblick auf Wirksamkeit und geringe Nebenwirkungen ist dieses Wirkstoff‐System den derzeit klinisch verwendeten überlegen.

The current study supports a role for TLR4 in the inflammatory reaction after short-term MV in healthy lungs. Increasing the understanding of the innate immune response to MV may lead to future treatment advances in ventilator-induced lung injury, in which TLR4 may serve as a therapeutic target.

Mechanical ventilation induces reversible cytokine increase and leukocyte influx with preserved tissue integrity. This model offers opportunities to study the pathophysiologic mechanisms behind ventilator-induced lung injury and the contribution of MV to the "multiple-hit" concept.

Neuropathic pain is often accompanied by stress, anxiety and depression. Although there is evidence for involvement of corticotropin-releasing factor (CRF), the detailed neuronal basis of these pain-related mood alterations is unknown. This study shows that peripheral mononeuropathy was accompanied by changes in limbic forebrain CRF, but did not lead to changes in the functioning of the hypothalamo-pituitary-adrenal axis and the midbrain Edinger-Westphal centrally projecting (EWcp) neuron population, which play main roles in the organism's response to acute pain. Twenty-four days after chronic constriction injury (CCI) of the rat sciatic nerve, the oval bed nucleus of the stria terminalis (BSTov) contained substantially more Crf mRNA as did the central amygdala (CeA), which, in addition, possessed more CRF. In contrast, Crf mRNA and CRF contents of the hypothalamic paraventricular nucleus (PVN) were unaffected by CCI. Similarly, EWcp neurons, producing the CRF family member urocortin 1 (Ucn1) and constitutively activated by various stressors including acute pain, did not show an effect of CCI on Ucn1 mRNA or Ucn1. Also, the immediate early gene products cFos and deltaFosB in the EWcp were unaffected by CCI. These results indicate that neuropathic pain does not act via the HPA-axis or the EWcp, but includes a main role of Crf in the limbic system, which is in clear contrast to stressors like acute and chronic pain, which primarily act on the PVN and the EWcp.
