Developing a new experimental model of abdominal compartment syndrome.

Objective: To describe an experimental, unprecedented model that mimics the abdominal compartment syndrome (ACS).

Methods: twenty rats were randomly divided into four groups. To simulate ACS intra-abdominal hypertension (IAH) was induced by inserting cotton surgical dressing (Zobec ®), 15x15cm (intra-abdominal pressure constant and equal to 12 mmHg) associated with hypovolemia induced by withdrawing blood, keeping mean arterial pressure (MAP) around 60 mmHg (HYPO).

Bone marrow mononuclear cell therapy led to alveolar-capillary membrane repair, improving lung mechanics in endotoxin-induced acute lung injury.

The aim of this study was to test the hypothesis that bone marrow mononuclear cell (BMDMC) therapy led an improvement in lung mechanics and histology in endotoxin-induced lung injury. Twenty-four C57BL/6 mice were randomly divided into four groups (n = 6 each). In the acute lung injury (ALI) group, Escherichia coli lipopolysaccharide (LPS) was instilled intratracheally (40 μg, IT), and control (C) mice received saline (0.
