A Novel Porcine Model of Ischemia-Reperfusion Injury After Cross-Clamping the Thoracic Aorta Revealed Substantial Cardiopulmonary, Thromboinflammatory and Biochemical Changes Without Effect of C1-Inhibitor Treatment.

Ischemic injury worsens upon return of blood and innate immunity including the complement system play a central role in ischemia-reperfusion injury (IRI) as in thoracic aortic surgery. Complement component1 inhibitor (C1-INH) has been shown to reduce IRI and is a broad-acting plasma cascade inhibitor. We established a new porcine model of IRI by cross-clamping the thoracic aorta and evaluated the global changes occurring in organ function, systemic inflammatory response and organ damage with or without treatment with C1-INH-concentrate.

Plantar puncture wounds in children: analysis of 80 hospitalized patients and late sequelae.

Background: Puncture wounds in the feet of children present a clinical dilemma.

Objectives: To evaluate our approach, we reviewed the charts and all available images of 80 children admitted to our institution because of plantar punctures from 1988 to 1999.

Methods: The charts of 80 children were reviewed retrospectively.

The effects of enoxaparin on the reparative processes in experimental osteonecrosis of the femoral head of the rat.

The blood supply of one femoral head of 6-month-old rats was severed by incising the periosteum of the neck and cutting the ligamentum teres. The rats were killed on the 30th postoperative day and the femoral bones were obtained for semiquantification of the reparative processes in the necrotic heads. Fourteen rats were treated with enoxaparin and 14 untreated animals served as controls.
