Evidence for oral shedding of herpes simplex virus Type I (HSV) indicating endogenous viral reactivation as a measure of depressed host defense was sought in 44 critically ill surgical patients. Eighteen (41%) of these showed persistent HSV shedding. None of 50 controls showed HSV shedding, but 4 (10%) of 42 patients undergoing elective surgery showed(More)
The objective of this study was to determine the effects of the Halothane (N) and Rendement Napole (RN) genes on carcass and meat quality characteristics in pigs. Halothane and RN carrier (Nn/RN- rn+) Hampshire boars (n = 4) were mated to dams that were homozygous for the normal allele of both genes (NN/rn+ rn+) to produce progeny of four genotypes: 1,(More)
The relationships between glycolytic potential and growth performance, carcass traits, and pork quality were investigated in a group of 72 pigs from the same genetic line. Glycolytic potential (GP) was determined on live-animal biopsy samples and postmortem samples taken from the longissimus muscle, and free glucose concentration was measured on the exudate(More)
BACKGROUND Acute graft rejection (AR) following renal transplantation results in reduced graft survival. However, there is uncertainty regarding the definition, aetiology and long-term graft and patient outcome of AR occurring late in the post-transplant period. AIM To determine if rejection episodes can be classified by time from transplantation by their(More)
Serum protein levels were found to be markedly reduced in 44 critically ill surgical patients after they had been resuscitated in an intensive therapy unit (ITU). There was no difference in initial protein levels between those patients who survived and those who died, or between those patients who reacted to skin testing with recall antigens and those who(More)
The objective of this study was to compare the effects of longissimus glycolytic potential (GP) and of time of feeding of supplemental magnesium sulfate heptahydrate on carcass and pork quality traits. The study was carried out in a 2 x 2 x 4 factorial arrangement; the treatments were sex (castrate vs gilt), GP (Low [normal] vs High), and time of feeding of(More)
A total of 192 pigs were utilized in a 2×3×3 factorial arrangement with an additional control treatment. The treatments were: (1) magnesium level (1.6 vs. 3.2 g of magnesium pig(-1) day(-1)); (2) magnesium source (sulfate vs. proprionate vs. proteinate); (3) feeding duration (5 vs. 2 vs. 1 day), and a control (no supplementary magnesium).

1. Extraneuronal uptake of noradrenaline (NA) was examined in the cat spleen first by perfusing with NA for 10 min, followed by a 2-min wash to clear the extracellular fluid, then measuring the amount retained, its subcellular distribution and the tissue components involved as revealed by the development of the characteristic fluorescence. Secondly, thin(More)
Ultrasound examinations of the pelvis and kidney have been carried out following 68 renal transplants. In 16 patients moderate sized or large perirenal or pelvic fluid collections were demonstrated. The composition of the fluid was lymph in seven cases, pus in four, blood in three and urine in two. Ten of these 16 patients had clinical features compatible(More)
