Studies on the mechanism of PMN activation II. by triggering the alternative pathway of complement activation

1982

By means of cobra venom factor (CVF) it is demonstrated that the stimulation of hexosemonophosphate shunt (HMPS) of human polymorphonuclear leukocytes (PMN) by zymosan (Z) and dextran sulfate (DS) is caused by at least two modes of activation: (a) via activation caused by phagocytosis, (b) via activated alternative pathway of complement activation (APC). Active factors of APC presented with phagocytizable objects strongly enhance activation of PMN. The effect of APC can be observed in serum-containing as well as in serum-free cultures. It can be demonstrated that in serum-free cultures the factors of APC participating in the activation of PMN are supplied by monocytes. By the use of synthet…

Inhibitory effects of okadaic acid on rat uterine contractile responses to different spasmogens

1997

In the present study, we examined the effects of okadaic acid, a selective inhibitor of type I and 2A protein phosphatases, on the mechanical responses evoked by oxytocin, K + - and Na + -modified solutions and ouabain in estrogen-primed rat myometrium. Oxytocin elicited a rapid, phasic contraction followed by rhythmic oscillations. The phasic response was partially resistant to the absence of external Ca 2+ . Okadaic acid (1 μM) and the L-type calcium channel blocker nifedipine (1 μM) abolished the oscillatory component and reduced the initial, phasic response to about 80% of the control response. High K + (60 mM) solution, ouabain (1 mM), K + -free medium and low Na + (25 mM) solution ind…

Guidelines for Youth Sports Clubs to Develop, Implement, and Assess Health Promotion Within Its Activities

2014

The settings approach to health promotion is a world-known concept concerning settings like city, hospital, school, and workplace. The concept has also been used in some regionally specific settings, such as island, prison, or university. However, there are still many, often noninstitutional, settings that have a lot of potential but have not yet been recognized. One of the newcomers is the youth sports club, which has the potential to reach a lot of children and adolescents and is effective, via its casual educational nature based on voluntary participation. According to research, health is an important aim for most youth sports clubs, but it has not been converted into practical actions.…

Opioid Responsiveness-Primary Diagnosis Relationship in Advanced Cancer Patients Followed At Home

2000

The aim of this study was to evaluate the influence of the primary cancer on pain characteristics and opioid response, in terms of analgesia and adverse effects, in advanced cancer patients followed at home. A prospective study was carried out in a sample of 434 consecutive advanced cancer patients who required opioids during the last four weeks of life. One hundred eighty-one patients received opioids for longer than the four weeks and were considered for this analysis. Demographic data, primary diagnosis, and pain mechanisms were recorded, and mean opioid doses, pain intensity, and symptoms were assessed at weekly intervals during the last four weeks of life. In the group of 181 patients,…

Improving End-of-Life Care in Hospitals

2013

Objectives: To explore and document the experiences and expectancies of bereaved family members concerning the end-of-life (EOL) care of their deceased relative in a general hospital setting. Methods: Cross-sectional study using a questionnaire that included open-ended questions. Free-text answers were evaluated with qualitative content analysis. A total of 270 family members provided information about improvements in inpatient care. Results: Families described structural deficiencies. Furthermore, they requested a more holistic patient health care beyond medical treatment and expressed the wish for more professional support for families. Discussion: The view of bereaved families confirmed …

Conversion ratios for opioid switching in the treatment of cancer pain: a systematic review

2011

In this paper we describe the results of a systematic search of the literature on conversion ratios during opioid switching. This is part of a project of the European Palliative Care Research Collaboration to update the European Association for Palliative Care recommendations for the use of opioid analgesics in the treatment of cancer pain. Studies were eligible for inclusion if they involved adult patients with chronic cancer pain, contained data on opioid conversion ratios, were prospective and were written in English. Thirty-one studies were identified and included. The majority of the studies had methodological flaws and were not designed to explore or demonstrate equianalgesic dose da…

Oxygen and glucose deprivation induces major dysfunction in the somatosensory cortex of the newborn rat

2005

The mechanisms and functional consequences of ischemia-induced injury during perinatal development are poorly understood. Subplate neurons (SPn) play a central role in early cortical development and a pathophysiological impairment of these neurons may have long-term detrimental effects on cortical function. The acute and long-term consequences of combined oxygen and glucose deprivation (OGD) were investigated in SPn and compared with OGD-induced dysfunction of immature layer V pyramidal cortical neurons (PCn) in somatosensory cortical slices from postnatal day (P)0-4 rats. OGD for 50 min followed by a 10-24-h period of normal oxygenation and glucose supply in vitro or in culture led to pron…

Eine vergleichende Untersuchung zum Reizdarmsyndrom bei konsekutiven Patienten zweier internistischer Ambulanzen

2001

OBJECTIVES We investigated the nature of illness behavior and the meaning of emotional deficiencies during childhood in patients with irritable bowel diseases (IBS). DATA A consecutive study in two tertiary referral centers was conducted with 48 patients suffering from irritable bowel diseases (IBS) and 91 patients with inflammatory bowel disease (IBD). METHODS The diagnosis of IBS was made by following the Manning criteria, a positive diagnosis of IBD was established through physical, endoscopic and radiologic examinations and was confirmed histologically. Psychological data were obtained by structured psychiatric interviews and psychological self-report measures (GBB). RESULTS We found th…

Antipsychotic drugs antagonize human serotonin type 3 receptor currents in a noncompetitive manner

2004

The serotonin type 3 (5-HT(3)) receptor is the only ligand-gated ion channel receptor for serotonin (5-HT). 5-HT(3) receptors play an important role in modulating the inhibitory action of dopamine in mesocorticolimbic brain regions. Neuroleptic drugs are commonly thought to exert their psychopharmacological action mainly through dopamine and serotonin type 2 (5-HT(2)) receptors. Except for clozapine, a direct pharmacological interaction of neuroleptics with 5-HT(3) receptors has not yet been described. Using the concentration-clamp technique, we investigated the effects of flupentixol, various phenothiazines, haloperidol, clozapine and risperidone on Na(+)-inward currents through 5-HT(3) re…
