Changes in the adrenergic mechanisms of cerebral arteries after subarachnoid hemorrhage in goats.
1994
We have examined the effects of experimental subarachnoid hemorrhage (SAH), induced by delivering autologous blood into the subarachnoid space, on the adrenergic mechanisms of the goat cerebrovascular bed. To achieve this, the response to noradrenaline was recorded both in vivo, by measuring cerebral blood flow in unanesthetized animals, and in vitro, by recording isometric tension in isolated cerebral arteries. In addition, we checked the function of adrenergic innervation by measuring the tritium efflux evoked by electrical stimulation in cerebral arteries preloaded with [3H]-noradrenaline, and we examined this innervation by using both fluorescent and electron transmission microscopy.

Differential effects of hypothermia on neuronal efflux, release and uptake of noradrenaline
1972
Isolated rabbit hearts were perfused at 34° (control), 24° or 12°C. The neuronal efflux of noradrenaline after perfusion with the amine for 1 h was depressed at 24° C (Q 10 about 5) in the presence or absence of desipramine; at 12°C the efflux was below the limit of estimation. Moderate reduction of the temperature (24° C) decreased the removal of perfused noradrenaline to about 60% of the control value and caused a 1.7-fold increase of the output of noradrenaline evoked by sympathetic nerve stimulation. It is concluded that the extremely temperature-dependent efflux of noradrenaline across the axonal membrane is not part of the release of noradrenaline evoked by nerve stimulation.
Digital health interventions in children with asthma
2020
Abstract Although healthcare providers are actively involved in offering education, information and interventions for asthmatic patients, medication and therapeutic adherence remain low in the paediatric population, with estimates suggesting that adherence rates hover below 50%. A range of available digital health interventions has been explored in paediatric asthma with promising but variable results, limiting their widespread adoption in clinical practice. They include emerging technologies that yield the advantage of tracking asthma symptoms and medications, setting drug reminders, improving inhaler technique and delivering asthma education, such as serious games (video games designed fo…
Stimulation of calcium uptake by norepinephrine or high external potassium in human calyces and renal pelvis.
1989
The effects of stimulation with either 10 mumol/l norepinephrine or 85 mmol/l extracellular potassium concentration on calcium uptake were studied in muscle strips from human renal calyces and from the renal pelvis. The apparent uptake of calcium under control conditions was essentially complete after 30 min. Stimulation of the muscle strips with norepinephrine or high external potassium significantly (P less than 0.05) increased the calcium uptake over the control values at 30 and 100 min, whereas 45Ca efflux was virtually not affected. It is concluded that the mechanical responses of the muscle strips to norepinephrine or high external potassium correspond with an increased uptake of calc…
Vascular effects of progesterone: Role of cellular calcium regulation
2001
Abstract —Vascular actions of progesterone have been reported, independently of estrogen, affecting both blood pressure and other aspects of the cardiovascular system. To study possible mechanisms underlying these effects, we examined the effects of P in vivo in intact rats and in vitro in isolated artery and vascular smooth muscle cell preparations. In anesthetized Sprague-Dawley rats , bolus intravenous injections of P (100 μg/kg) significantly decreased pressor responses to norepinephrine (0.3 μg/kg). In vitro, progesterone (10 −8 to 10 −5 mmol/L) produced a significant, dose-dependent relaxation of isolated helical strips, both of rat tail artery precontracted with KCl (60 mmol/L) or a…
Efficacy and tolerability of a plant-based, multi-component cream (Ginetrox®) in vulvovaginal disorders of the genitourinary syndrome during menopaus…
2017
BACKGROUND Genitourinary syndrome of menopause (GSM) is a symptomatic condition including vaginal dryness, irritation, dyspareunia and recurrent urinary tract infections which affects 40-54% of post-menopausal women. Although several estrogen-based therapies are available, it is generally preferable to avoid hormonal therapy, particularly in women with mild symptoms or at risk for estrogen-responsive neoplasia. Therefore, the most common treatment options are over-the-counter vaginal creams for symptomatic relief. METHODS Thirty-three postmenopausal women suffering from GSM were enrolled in this observational study. A multi-component cream (Ginetrox®, Indena, Milan, Italy) was applied on th…
Standardisiertes postoperatives Schmerztherapieschema in der Orthopädie
2006
In order to treat patients with postoperative acute pain effectively, we have developed a standardised algorithm for analgesia. This process includes three levels and the appropriate supply of medication. The therapy level is defined based on the scale of the operation. Accordingly, the prescription and handling of the pain medication is simplified for the attending physician and nurses. The pain level has to be measured by the nursing staff sing a visual analogue scale (VAS). Thus, the efficiency of the analgesics will be continuously evaluated and controlled. The standardised supply medication can be applied in those cases with pain levels > or = 4 (VAS). It is possible to up- or down-gra…
Disease control and treatment pathways of asthma patients after initiating ICS/LABA
2019
Introduction: GINA guidelines recommend medium dose (MED) and high dose (HD) ICS/LABA as the preferred controller for step 4 asthma patients and clinicians should consider step up/down based on their patients’ asthma control. Limited data is available on how step 4 patients respond to ICS/LABA and how they step up/down in clinical practice. Methods: We conducted a retrospective cohort study using UK Clinical Practice Research Datalink to assess control status of asthma patients in one year after initiating a MED or HD ICS/LABA between 2007 and 2015, and examined their treatment pathways within one year after the treatment initiation. Results: 29,229 and 16, 575 patients initiated MED and HD…
Bone marrow punctures and pain
2004
Abstract We prospectively analysed pain in 263 patients induced by a frequent diagnostic procedure for oncologists, specifically the bone marrow puncture. Substantial pain (5 and more out of 10 on a numerical rating scale) was reported by 30.4% of patients, but physicians did not realize this procedure-related pain of patients in more than 50% of such punctures. The necessity for improved analgesia is emphasized by the fact, that at least 50% of patients experiencing substantial pain wished to receive concomitant medication in future punctures. Duration of the procedure was identified as sole independent predictive factor for patients’ pain intensity, while patients’ characteristics like ge…
Platelet Activity in Relation to Smoke and Exercise in Patients with Chronic Obstructive Lung Disease: Effects of Platelet Antiaggregating Drugs
1984
Lung tissue is involved in the synthesis and/or metabolism of many vasoactive substances such as histamine, serotonin, dopamine, norepinephrine, bradikinin, angiotensin II and prostaglandins (1).
