Protective impact of landiolol against acute lung injury following hemorrhagic shock and resuscitation in rats.

ABSTRACT: Hemorrhagic shock and resuscitation (HSR) induces pulmonary inflammation, leading to acute lung injury (ALI). Notably, blocking β1 receptors can lead to organ protection through anti‑inflammatory and anti‑apoptotic effects. Additionally, although the β1 receptor pathway is blocked by the β1 blocker, the β2 receptor pathway may be preserved and activate the 5' adenosine monophosphate‑activated protein kinase (AMPK) pathway. The present study aimed to examine whether administration of the β1 blocker landiolol could achieve lung protection in a model of HSR‑ALI, alongside improvements in inflammation and apoptosis. Male Sprague‑Dawley rats underwent hemorrhage keeping their mean arterial pressure at 30 mmHg for 1 h. Resuscitation by reinfusion was initiated to restore blood pressure to pre‑he
