BACKGROUND Computed tomographic pulmonary angiography (CTPA) has simplified the diagnostic approach to patients with suspected pulmonary embolism (PE). However, PE diagnosis is still probabilistic and CTPA should be used with caution in some patient groups, such as patients with severe renal insufficiency and pregnant women. Among alternative imaging tests,(More)
When decreasing the energy value of broiler diets, nonstarch polysaccharide degrading enzymes, such as xylanase, are often used. In doing so, they are assigned an energy value and considered to contribute energy to the diet. The aim of this study was to determine the effect of decreasing energy in a broiler diet by 100 kCal/kg on performance and whether the(More)
In a controlled study, the distribution and elimination kinetics of hydroxyethyl starch as well as clinically relevant parameters were determined in horses. The half-life of the first phase was 5.59 hours, that of the second phase 122.22 hours. During the first phase, hydroxyethyl starch persisted almost exclusively intravascularly. The results of this(More)
INTRODUCTION The safety of supplementing broiler feed with a standardised herbal extract, Solanum Glaucophyllum Standardised Leaves (SGSL) containing glycosylated 1a,25-dihydroxyvitamin D3 (1,25(OH)2D3) and standardised to contain 10 µg/g 1,25(OH)2D3 equivalent, was examined in two studies. In a first study, we examined the potential of SGSL to substitute(More)
BACKGROUND Topical corticosteroids are the only effective measure in serious inflammatory corneal and conjunctival diseases. Although results obtained with topical cyclosporin A are encuraging it is not effective in all patients. The mode of action of Fk506 is similar to that of cyclosporin A, i.e. it exerts an inhibitory effect on transcription of(More)
A natural form of 1,25-dihydroxyvitamin D3 (1,25(OH)2D3), the active metabolite of vitamin D, was identified in glycosylated form in Solanum glaucophyllum (SG). Solbone P, an extract of SG with high and homogenous content of glycosylated 1,25(OH)2D3, was chemically characterized and produced under GMP conditions. Three different doses of glycosylated(More)
We present a literature review on current techniques of intravenous regional anesthesia and intravenous regional antibiosis of the distal limb in cattle. Our own experiences performing a combined procedure of intravenous anesthesia and antibiosis (10 million I.U. benzylpenicillin sodium dissolved in 15-20 ml 2%-lidocaine hydrochloride) are discussed in(More)
CGP 48933, a new angiotensin-II-receptor antagonist, has been shown to lower intraocular pressure (IOP) in two different rabbit glaucoma models in a dose-dependent manner after local application. As a further step a pilot study was performed in human eyes. The trial consisted of three parts. Parts 1 and 2 comprised a double-masked intraindividual trial(More)
The chromatin organization of living mammalian cells was probed using 8-methoxypsoralen (MOP). In intact cells, MOP intercalates into DNA domains which are also preferentially accessible to micrococcal nuclease. After UV365 nm irradiation of MOP-treated cells, this chemical forms bifunctional adducts crosslinking the two strands of DNA. Following extraction(More)
Select medium and substratum conditions were investigated for their effects on semiconservative DNA synthesis in essentially pure primary cultures of bile ductular epithelial cells that were initially isolated from cholestatic rat livers at 6 to 10 wk after bile duct ligation. DNA synthesis in these cultured cells was serum-dependent, being at its highest(More)
