Metabolism of vitamin E in sheep.
I . The metabolism of tritium-labelled tocopherol was investigated in thirty-six wethers and forty-two ewes fed on hay known to produce nutritional muscular dystrophy (NMD). 2. In one experiment, the effect of selenium or vitamin E or both on the metabolism of tritium-labelled tocopherol was studied. No difference was found in the incorporation rate of radioactivity in tissues due to the additi...
متن کاملDisposition kinetics and dosage regimen of vitamin E administered intramuscularly to sheep.
Three experiments were conducted to estimate the effects of single intramuscular (IM) administrations of vitamin E on blood plasma and tissue concentrations of alpha-tocopherol in sheep. In Expt 1, plasma kinetics of alpha-tocopherol in sheep (n 30) were investigated following IM administration of three doses (ten sheep/dose) of DL-alpha-tocopheryl acetate, (20, 40 and 60 mg/kg live weight). Pl...
متن کاملthe 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.
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...
متن کاملKinetics 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...
