triolein/edema

BACKGROUND Triolein emulsion infusion into the brain produces transiently increased vascular permeability. OBJECTIVE The purpose of this study was to find the minimum percentage of triolein emulsion required for studying vascular permeability with minimal brain edema. METHODS Sixty healthy cats were

OBJECTIVE In fat embolism, free fatty acid is more toxic than neutral fat in terms of tissue damage. We evaluated the hyperacute embolic effects of triolein and oleic acid in cat brains by using MR imaging and electron microscopy. METHODS T2-weighted imaging, diffusion-weighted imaging, and

OBJECTIVE To evaluate the magnetic resonance imaging and electron microscopic findings of the hyperacute stage of cerebral fat embolism in cats and the time needed for the development of vasogenic edema. METHODS Magnetic resonance imaging was performed at 30 minutes (group 1, n = 9) and at 30

The authors report the case of a young woman with right lower limb edema who also presented one steatorrhea. Her clinical history is typical for one primary lymphedema and the lymphoscintigraphic investigation of the lower limbs confirms the diagnosis. The scan showed the absence of the right iliac

BACKGROUND The pathophysiologic mechanism of the fat embolism syndrome is poorly understood. This study was designed to determine the effects of fat emboli on pulmonary vasculature. METHODS Triolein was infused into isolated rat lungs perfused with Krebs-Henseleit buffer. Pulmonary arterial pressure

BACKGROUND Triolein emulsion embolization into the carotid artery depicts reversible increased vascular permeability that can promote the effect of chemotherapy or can reduce the amount of chemotherapeutic drugs for equivalent effectiveness. OBJECTIVE To establish the minimum dosage of 0.5% triolein

The acute effects of a triolein infusion in dogs were secondary to the mechanical effects of this neutral fat which was distributed in the pulmonary and systemic vascular tree of all organs without inflammatory change. Hypoxia developed immediately and became progressively worse as the infusion was

OBJECTIVE The purpose of study was to evaluate the feasibility of brain magnetic resonance (MR) images of the rat obtained using a 1.5T MR machine in several blood-brain barrier (BBB) experiments. METHODS Male Sprague-Dawley rats were used. MR images were obtained using a clinical 1.5T MR machine. A

Intravenous infusion of oleic acid into experimental animals causes acute lung injury resulting in pulmonary edema. We investigated the mechanism of oleic acid lung injury in sheep. In experiments with anesthetized and unanesthetized sheep with lung lymph fistulas, we measured pulmonary arterial and

Acrolein is a highly toxic, reactive, and irritating aldehyde that occurs as a product of organic pyrolysis, as a metabolite of a number of compounds, and as a residue in water when used for the control of aquatic organisms. It is an intermediate in the production of acrylic acid, DL-methionine, and

The action of histamine in oleic acid (OA)-induced injury was investigated using the isolated guinea pig lung perfused with blood-free media. OA infusion caused a significant increase in pulmonary arterial pressure, airway inspiratory pressure, lung weight, and protein flux across the

We examined cardiotoxicity induced by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the chick embryo and the cardiac expression of transcription factors, the aryl hydrocarbon receptor (AhR) which binds TCDD, and its dimer partner, the AhR nuclear translocator (Arnt). Chicken eggs were injected with

Twenty-two adult dogs were each given a single, 30-minute injection of 1.5 ml/kg body weight of pure triolein, and their pulmonary, hepatic, renal, and cerebral morphology was observed for 1, 2, 3, 4, 5, 6, 15, 24, and 48 hours; 3,4, and 5 days; 1 and 2 weeks; and 1 month after the injection. A

OBJECTIVE Fat embolism syndrome is a serious complication observed after trauma, orthopedic surgery, and cardiac surgery. We investigated brain damage in relationship to temporal profiles of water channel aquaporin 4 (AQP4) and astrocyte response to fat embolism in rats. METHODS Triolein (2 microl)

The toxicity of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and related compounds in birds has been well-established in laboratory and field studies. Observed effects of TCDD and related chemicals in birds include developmental deformities, reproductive failure, liver damage, wasting syndrome and
