Effects of bovine colostrum, foal serum immunoglobulin concentration and intravenous plasma transfusion on chemiluminescence response of foal neutrophils
Since the concentration of opsonins contained in foal serum decreases as maternal immunity wanes, we evaluated the effects of age and serum IgG concentration on phagocytic and serum opsonizing activity of foals during the first month of life. The second purpose of this study was to evaluate the effects of bovine colostrum on chemiluminescence response of foal neutrophils. The third purpose of this study was to evaluate the efficacy of intravenous plasma transfusion in stimulating CL of neutrophils collected from clinically ill foals
Cerebrovascular hemodynamic assessment adds new information to standard anatomic MR imaging and improves patient care. This article reviews the theoretic underpinnings of several potentially quantitative MR imaging-based methods that shed light on the hemodynamic status of the brain, including cerebral blood flow (CBF), cerebral blood volume (CBV), and contrast agent permeability. Techniques addressed include dynamic susceptibility contrast (which most simply and accurately estimates CBV), arterial spin labeling (a powerful method to measure CBF), and contrast-enhanced methods to derive permeability parameters such as the transport constant Ktrans.
