The effects of Ocimum basilicum (O. basilicum) and its constituent, rosmarinic acid, on total and differential blood WBC, serum levels of NO2, NO3, MDA, thiol, SOD and CAT in sensitized rats were examined. The study was performed in control animals (group C) and eight groups of sensitized rats to ovalbumin which were given drinking water alone (group S), drinking water containing three concentr...
BACKGROUND During abdominal surgery under regional anesthesia, nausea may happen due to several contributing factors. This study compared the effects of ondansetron and dexamethasone on nausea and vomiting under spinal anesthesia. METHODS One hundred and twenty patients of 15 to 35 years old with ASA class I and II were enrolled. Before administering either ondansetron or dexamethasone, blood p...
BACKGROUND Dexamethasone is frequently administered in the perioperative period to reduce postoperative nausea and vomiting. In contrast, the analgesic effects of dexamethasone are not well defined. The authors performed a meta-analysis to evaluate the dose-dependent analgesic effects of perioperative dexamethasone. METHODS We followed the PRISMA statement guidelines. A wide search was perfor...
Glucocorticoids paradoxically exert both stimulatory and inhibitory effects on the proliferation of cultured rat hepatocytes. We studied the effects of dexamethasone, a synthetic glucocorticoid, on the proliferation of cultured rat hepatocytes. The timing of growth factor addition modified the action of high-dose dexamethasone (10(-6) M) on DNA synthesis. When we added transforming growth facto...
Until recently, the synthetic glucocorticoid dexamethasone was commonly used to lessen the morbidity of chronic lung disease in premature infants. This practice diminished as dexamethasone use was linked to an increased incidence of cerebral palsy and short-term neurodevelopmental delay. Of more concern is the fact that we know little regarding dexamethasone effects on long-term neurodevelopmen...
the present study describes the changes in expression of hydroxy- carboxylic acid receptor 2 (hca2 receptor) in femoral epiphysis and metaphysis of rats with glucocorticoid-induced osteoporosis (gio). 16 growing male sprauge dawley rats were randomly divided into two equal groups consisting of normal control and rats that were rendered osteoporotic by receiving 0.1 mg/kg/day dexamethasone throu...
Chronic treatment with glucocorticoids increases the mass of adipose tissue and promotes metabolic syndrome. However little is known about the molecular effects of dexamethasone on adipose biology. Here, we demonstrated that dexamethasone induces progenitor cells to undergo adipogenesis. In the adipogenic pathway, at least two cell types are found: cells with the susceptibility to undergo staur...
Simultaneous plasma dexamethasone and cortisol levels were followed at intervals over 8 hour periods on 40 occasions in 19 subjects who received regular high dosage dexamethasone therapy (rarely less than 12 mg a day) for various neurological and neurosurgical conditions. Lower dexamethasone doses (for example 2 mg daily for 2 days) normally suppress adrenal cortical production of cortisol to b...
The prophylactic antiemetic efficacy of combined granisetron and dexamethasone was evaluated in a randomized double-blind manner in 88 patients undergoing general anaesthesia for major gynaecological surgery. Immediately after recovery from anaesthesia, patients received a single dose of either placebo (saline, n = 22), granisetron (20 micrograms.kg-1, n = 22), dexamethasone (8 mg, n = 22) or c...
Prolonged exposure to dexamethasone (DEX), a synthetic glucocorticoid receptor agonist, has been shown to induce neuronal cell death in the hippocampus. Cell death is particularly pronounced in the CA3 pyramidal neurons, inducing cognitive dysfunction. The aim of this study was to investigate the effect of melatonin on hippocampal CA3 pyramidal cells in dexamethasone treated mice. The mice rece...
