In order to study the influence of the hypothalamic-pituitary-adrenal axis on the levels of endogenous digitalis-like substances (EDLS) in plasma and urine, eight healthy subjects (25-40 years old) were given dexamethasone 1 mg orally and tetracosactide (an ACTH analog) 0.25 mg i.v., on separate occasions. The circulating levels of EDLS, TSH, PRL and AVP following administration of either test dru
To identify factors that regulate the levels of immunoreactive digitalis-like substances (irEDLS) in body fluids, two studies were carried out. Plasma and urine levels of irEDLS were measured in uremic and normal subjects. Extracted material was fractionated (12 fractions) and assayed by digoxin radioimmunoassay. In four fractions, higher levels of irEDLS were found in uremic than in normal plasma
The basal and TRH (Thyrotropin-Releasing Hormone) stimulated TSH (Thyrotropin) and PRL (Prolactin) responses (incremental area; IA) to 200 micrograms TRH was studied in 13 pre- and 13 postmenopausal women of 60 years of age. Both groups consisted of healthy women, none had goiter and all were negative for thyroid autoantibodies. The serum levels of TSH, T3, T4 and SHBG (sex hormone-binding globuli
The effect of exposure to toluene on plasma concentrations of testosterone, prolactin, luteinising (LH) and follicle stimulating (FSH) hormones was investigated in 47 rotogravure printers (time weighted average air toluene below 80 ppm; blood toluene concentration post-shift 0.19-7.99 mumol/l) and compared with a reference group. Increasing exposure concentrations of toluene (concentrations less t
Twenty toluene-exposed rotogravure printers, without signs of solvent-induced toxic encephalopathy, had lower median plasma levels of follicle stimulating hormone (FSH) (3.2 vs. 4.9 IU/L; p = .02) and luteinizing hormone (LH) (6.4 vs. 7.2 IU/L; p = .05) and also lower serum levels of free testosterone (7.8 vs. 86.8 pmol/L; p = .05), respectively, than 44 unexposed referents. The individual time-we
Fifteen premenopausal women were investigated in the follicular phase of the menstrual cycle with two TRH tests within an interval of 48 to 96 h. Ninety min before each TRH test either 10 mg metoclopramide or saline was injected iv in randomized order. The same procedure was repeated in the following menstrual cycle after pretreatment with T4 (0.5 mg daily for 6-14 days). At least 2 months later t
Exposure to elemental mercury (Hg) vapour results in an accumulation of Hg in the pituitary, the thyroid, and the testis. In this study, basal serum concentrations of pituitary hormones (thyrotrophin (TSH), prolactin (PRL), follicle stimulating hormone (FSH), and luteinising hormone (LH] or their response after administration of thyrotrophin and gonadotrophin releasing hormones did not differ betw
Plasma levels of the neuropeptides, vasoactive intestinal polypeptide (VIP, neuropeptide Y (NPY), calcitonin gene-related peptide (CGRP), substance P, and galanin were determined in 15 hyperthyroid patients before and at 3 occassions during 38 weeks of treatment. Treatment was performed with either 131I alone or with carbimazole, with combination of carbimazole and thyroxine, or with subtotal thyr
In 10 hyperthyroid women studied in the follicular phase of the menstrual cycle, basal plasma PRL was normal, but PRL release after TRH was significantly suppressed compared with that in 11 control women. The suppressed PRL response to TRH was not explained by changes in serum estradiol or sex hormone-binding globulin. It recovered after treatment of hyperthyroidism. When normal women were treated
In nine hyperthyroid women studied in the follicular phase of the menstrual cycle basal plasma LH concentrations and LH and FSH responses to GnRH were increased compared to those in nine normal women. The increased gonadotropin levels could not be related to changes in body weight or plasma estradiol or serum sex hormone-binding globulin levels, and they approached normal levels during or after tr
In 77 euthyroid subjects the mean ratio between serum triiodothyronine (S-T3) in nmol/l X 10(3) and serum thyroxine (S-T4) in nmol/l was 22.4 with a standard deviation of 4.3. The distribution of the ratio was close to Gaussian. It was not changed in subjects under estrogen effect. The ratio was increased in hypothyroid subjects suggesting a mechanism preserving S-T3 better than S-T4 in thyroid fa
We measured the thyrotropin response (delta TSH) to 200 micrograms of thyroliberin in 131 subjects without thyroid dysfunction or other disease and with basal values for thyroid function that were within the normal reference intervals for our laboratory. By univariate and multivariate statistical methods we found delta TSH to be significantly influenced by the basal concentration of thyrotropin (T
Introduction: Bedwetting, also known as enuresis, is the second most common chronic health problem among children and it affects their everyday life negatively. A first-line treatment option is the enuresis alarm. This method entails the child being awoken by a detector and alarm unit upon urination at night, thereby changing their arousal mechanisms and potentially curing them after 6–8 weeks of
BACKGROUND: Very preterm infants often require respiratory support and are therefore exposed to an increased risk of chronic lung disease and later neurodevelopmental disability. Although methylxanthines are widely used to prevent and treat apnea associated with prematurity and to facilitate extubation, there is uncertainty about the benefits and harms of different types of methylxanthines.OBJECTI
The aim of this study was to examine the influence of the Bachelor of Science Programme in Social Work at Lund University on students’ levels of empathy. We used a self-measurement tool that was distributed to all students (173) from the first semester and all students (135) from the last semester of the Bachelor of Science Programme in Social Work at Lund University, in order to determine whether
C-reportagsserien handlar om människor som har fått långvariga skador och nacksmärtor efter whiplashtrauman som uppkommit i samband med trafikolyckor. I reportageserien ingår två cases, en massageterapeut, nackskadespecialist- och sjuksköterska, och personal från försäkringskassan. Reportageserien är ett försök att belysa de problem som uppkommer efter ett whiplashtrauma, ur olika aspekter. Inrikt
The purpose of this study is to define the Tunisian’s perceptions and understanding of the Tunisian Revolution. From the description of the socio‐economic and political contexts in Tunisia before the revolution, it draws the roots of the social uprising. Describing the event in itself, it explains the several steps crossed by the Tunisian population during their struggle for the establishmentof a
