Glutaraldehyde-preserved bovine pericardium (GPBP) is evaluated as a bioprosthesis for the reconstruction of surgical defects in the thoracoabdominal wall. The mechanical properties of bovine pericardium preserved at different concentrations of glutaraldehyde were studied. Samples preserved in 0.5% glutaraldehyde showed a significantly higher tensile(More)
The purpose of this project was the development of a small animal model and the use of external gamma imaging for the study of acute post-inhalation permeability changes. New Zealand white rabbits were anesthetized with ketamine and acepromazine IM, intubated, and a catheter placed in an ear artery. Smoke was produced by burning absorbent cotton in a(More)
Nine marine otters (Lontra felina) were anesthetized 15 times with a combination of ketamine (5.3 +/- 0.9 [range: 4.5-8.0] mg/kg) and medetomidine (53 - 9 [range: 45-80] microg/kg) i.m. by hand syringe for the placement of radiotransmitters. Times to initial effect and induction period ranged from 1.1 to 5.0 min and 1.8 to 5.4 min, respectively. Minor(More)
The geographical distribution of the Chilean flamingo (Phoenicopterus chilensis) includes the southern-central Neotropics. Despite its wide distribution, currently there is no dietary information on its southern distribution range. From June to September 2011, we quantified the diet and prey availability of the Chilean flamingo in the marine wetland of(More)
An animal model utilizing gamma imaging was used to examine pulmonary edema of an inhalation injury model. Tests were conducted using radiolabeled tracers and a dual indicator dilution technique as well as gravimetric analysis of excised lungs to determine extravascular water formation. The effect of cimetidine (Tagamet, an H2 receptor antagonist) was(More)
A rabbit inhalation injury model using a dual tracer radioactive isotope technique (Rowland et al., 1986), has been utilized with small- and medium-sized molecular weight tracers. There is oedema formation at 2 h after smoke inhalation or fluid resuscitation and especially with the combination of inhalation injury and fluid resuscitation [corrected]. This(More)
