“…Research by Kaneda et al 29 and Fukunaga et al 30 established that pre-treatment of in vivo donor models with an endothelin receptor antagonist drug, TAK-044, improved cardiac functional recovery and post-operative function in hepatic allografts, respectively. In the current study we found that, not only are alveolar macrophages increased in BSD, when using a semiquantitative immunocytochemistry method, expression levels of ET-1, ET A R and ET B R in these chronic inflammatory cells are also significantly increased in this model compared with control animals.…”
