Kinetics of Glucose Metabolism in Sheep

Kinetics of allantoin metabolism in sheep.

The kinetics of allantoin metabolism were studied in rumen-cannulated sheep by means of a single intravenous injection of [4,5-(14)C]allantoin. The decline in the specific radioactivity of allantoin in plasma following the injection of tracer was best described by a double exponential function, indicating that allantoin moves in and out of two or more kinetically distinct compartments. Sequeste...

Kinetics of ethanol metabolism in sheep.

Kinetic aspects of ethanol metabolism were studied in sheep after intravenous or intraruminal infusion of ethanol. Vmax and Km in fed animals were respectively 295 +/- 10 mg.h-1.l-1 (l = litre of body water) and 32.1 +/- 2.4 mg.l-1. Elimination half-life was 1.47 +/- 0.26 h. The corresponding values in the fasted animal were not significantly different. During venous infusion an increase in pla...

Maternal-foetal glucose kinetics in conscious, catheterised sheep.

Glucose metabolism in shorn and unshorn pregnant sheep.

1. Whole-body, hind-limb and uterine tissue metabolism of glucose was studied using a combination of isotopic and arterio-venous difference techniques in shorn and unshorn pregnant sheep over the final 4 weeks of pregnancy. This was combined with the measurement of the concentrations of oxygen and carbon dioxide in arterial blood and plasma concentrations of lactate, acetate, non-esterified fat...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
