Pulmonary microvascular dysfunction and pathological changes induced by blast injury in a rabbit model.

Background: Vascular leakage has been proven to play a critical role in the incidence and development of explosive pulmonary barotrauma. Quantitatively investigated in the present study was the severity of vascular leakage in a gradient blast injury series, as well as ultrastructural evidence relating to pulmonary vascular leakage.

Methods: One hundred adult male New Zealand white rabbits were randomly divided into 5 groups according to distance from the detonator (10 cm, 15 cm, 20 cm, 30 cm, and sham control).

Characteristics and mechanisms of extremity injuries caused by mine blasts in shoals.

Background: The characteristics of explosion in water are different from those in air and vary in different water depths. It is important to investigate the characteristics and mechanisms of extremity injuries caused by mine blasts in shoals.

Methods: A total of ninety New Zealand rabbits were randomly divided into four groups put in different depths of water (land group, midpoint of the thigh in the shoal 1 group, the xiphoid process in the shoal 2 group, and control group).
