Macrophages are regulated by hormones, cytokines, and other substances. We examined the effects of glucocorticoids (GC) on serum amyloid A (SAA) mRNA expression using an antisense SAA3 probe, and found that dexamethasone (DEX) and triamcinolone (TC) increased SAA3 mRNA expression by macrophage cell lines in a time- and concentration-dependent manner. Both an RNA polymerase II antagonist, alpha-...
The objective of this case-control study was to compare the efficacy and toxicity of lenalidomide plus dexamethasone (len/dex) versus thalidomide plus dexamethasone (thal/dex) as initial therapy for newly diagnosed myeloma. We retrospectively studied 411 newly diagnosed patients treated with len/dex (228) or thal/dex (183) at the Mayo Clinic. The differences were similar in a matched-pair analy...
Alveolarization is impaired in rats treated with dexamethasone (Dex) on postnatal days 4-13, but concomitant treatment with all-trans retinoic acid (RA) increases alveolar number. To determine whether morphological changes induced by Dex and/or RA predict changes in lung function at 1 mo, we assessed resting breathing parameters, dynamic compliance, ventilation required to maintain O(2) saturat...
Tissue adhesion is a common complication after surgery. In this work, a dexamethasone loaded polymeric micelles in thermosensitive hydrogel composite (Dex hydrogel) was prepared, which combined the anti-adhesion barrier with controlled release of anti-adhesion drug. Dexamethasone (Dex) was encapsulated in polymeric micelles (Dex micelles), and then the Dex micelles were loaded into biodegradabl...
Dexamethasone (Dex) is widely used to treat chronic inflammatory diseases in the clinic. Increasingly, there is more attention being paid to the side effect of Dex. In this study, we investigated the involvement and mechanism of Dex exposure in accelerating mineralization during long bone formation. We first determined that Dex exposure could accelerate long bone mineralization in vivo, but the...
To explore the protective effect of dexmedetomidine (Dex) on rats with renal ischemia-reperfusion injury and the influence of Dex on the expression of tight junction protein in kidney. Grouped 40 SPF male rats into 4 groups, sham operation group (group S), ischemia-reperfusion group (group I/R), pretreatment with Dex group (group Pre/Dex), post-treatment with Dex group (group Post/Dex), randoml...
Dexmedetomidine (DEX) may act as an antioxidant through regulation of TRPM2 and TRPV1 channel activations in the neurons by reducing cerebral ischemia-induced oxidative stress and apoptosis. The neuroprotective roles of DEX were tested on cerebral ischemia (ISC) in the cultures of rat primary hippocampal and DRG neurons. Fifty-six rats were divided into five groups. A placebo was given to contr...
In brain disorders, astrocytes change phenotype to reactive astrocytes and are involved in the induction of neuroinflammation and brain edema. The administration of glucocorticoids (GCs), such as dexamethasone (Dex), reduces astrocytic activation, but the mechanisms underlying this inhibitory action are not well understood. Endothelins (ETs) promote astrocytic activation. Therefore, the effects...
Dexmedetomidine (Dex) is a specific agonist of α2-adrenoceptor and was reported to have protective effect on a variety of organs, however the effect of Dex on hyperoxia-induced lung injury remains unknown. In the present study, Dex was administrated to newborn rats and its effect against hyperoxia-induced lung injury was examined. The results showed that, Dex significantly attenuated the aberra...
BACKGROUND The efficacy of dexamethasone (DEX) to reduce morbidity after paediatric tonsillectomy remains controversial. We evaluated the effect of 0.15 and 0.5 mg kg(-1) DEX on the incidence of postoperative nausea and vomiting (PONV) and on pain intensity after paediatric tonsillectomy. METHODS A total of 147 children aged 2-8 yr undergoing elective tonsillectomy were included in this prosp...
