The influence of external abdominal irradiation and cytostatic therapy on the vitamin status was studied in patients with cancer of the uterus, bladder or prostate and in patients with malignant lymphoma. It was found that the vitamin status of these patients at the beginning of therapy in general was adequate, though vitamin A and vitamin D levels were(More)
This report describes the first evaluation in humans of Ro 41-3696. Based on its preclinical profile, Ro 41-3696, a nonbenzodiazepine partial agonist at the benzodiazepine receptor, offers promising perspectives as an innovative hypnotic drug in that it does not exhibit most of the disadvantages associated with full agonists. Single oral doses of 0.1, 0.3,(More)
The present study was performed to study possibilities of early decision making for appropriate conveyor-line at future slaughtering of normal, clinically healthy finishing pigs. Blood was collected at slaughter from barrows (n = 112). A meticulous examination for subclinical pathological lesions was performed, revealing 5 groups of subjects listed in order(More)
The survival in vivo of 51Cr-labeled autologous human platelets, the serotonin uptake velocity, and the response to hypotonic stress were determined both before and after cryopreservation. Changes in platelet survival corresponded to changes in serotonin uptake velocity and response to hypotonic stress. No correlation was observed between the values of the(More)
Experiments were carried out with the IBM 2991 Blood Cell Processor in order to study the sedimentation behaviour of blood cells from human ACD blood during centrifugation. Based on this behaviour procedures were developed for plasmapheresis and leucapheresis using the Blood Cell Processor. Accumulation of platelets was observed to occur at the plasma-cell(More)
To investigate systemic serotonin (5-HT) metabolism in migraine, we determined platelet and platelet-free plasma concentrations of 5-HT, its precursors tryptophan and 5-hydroxytryptophan, and its main metabolite 5-hydroxyindoleacetic acid (5-HIAA), as well as the activities of the platelet enzymes monoamine oxidase and phenolsulfotransferase in classic and(More)
The objective of this study was to compare the bioavailability of s.c. and i.m. administration of human chorionic gonadotrophin (HCG; Pregnyl). In a randomized, single-centre, three-way cross-over study, 18 healthy pituitary-suppressed volunteers were assigned to single HCG injections of 5000 and 10,000 IU i.m. and 10,000 IU s.c. Rate (Cmax, t(max)) and(More)
Screening of androgens and estrogens in blood and a GnRH test were performed in 20 female patients with anorexia nervosa and in 10 lean and 10 normal weight healthy control subjects. Both control groups had regular ovulatory menstrual cycles. The investigation was performed in the mid-follicular phase. Several variables showed significant differences(More)
In a nationwide survey the nutritional status was assessed of 539 apparently healthy, independently living elderly aged 65-79 years. Anthropometric data showed no energy deficits. The prevalence of anemia was 4 and 1% among men and women, respectively. Many elderly showed a low level of 25-hydroxyvitamin D in plasma (less than 31 nmol/L: men 35%; women(More)
The effects of maximal performance capacity and different work load intensities on the response of free and sulfate-conjugated plasma catecholamines, prolactin (PRL), and cortisol were studied in six healthy male volunteers. In a first experiment, the volunteers had to perform a step-wise incremental bicycle ergometer test to determine the onset of blood(More)
