icariin/hypoxia

OBJECTIVE To investigate the effect of icariin on myocardial hypoxia reoxygenation injury and the possible mechanism. METHODS Neonatal Sprague-Dawley rat cardiomyocytes in primary culture were treated with different concentrations of icariin for 24 h prior to hypoxia/reoxygenation injury.

OBJECTIVE To study the effect of icariin on vascular endothelial cells (VECs) injury induced by hypoxia. METHODS The hypoxia-ischemia model was established. The effect of icariin on injury of VECs activity induced by hypoxia was determined by MTT assay. The levels of malondialdehyde (MDA),

OBJECTIVE Icariin, a prenylated flavonol glycoside isolated from traditional Chinese medicinal herb of the genus Epimedium, has been demonstrated to be a potential alternative therapy for osteoporosis, and its action mechanism so far has been mainly attributed to its phytoestrogenic property. As

Articular cartilage has poor capability for repair following trauma or degenerative pathology due to avascular property, low cell density and migratory ability. Discovery of novel therapeutic approaches for articular cartilage repair remains a significant clinical need. Hypoxia is a hallmark for

Introduction: Neonatal hypoxic-ischemic brain damage (HIBD) is a brain disease that is caused by perinatal asphyxia. Icariin (ICA), which is an active component of Epimedii (a Chinese medicinal herb), has been verified to demonstrate a

BACKGROUND This study investigated the role of Sirtuin 1 (SIRT1)/forkhead box O3 (FOXO3) pathway, and a possible protective function for Icariin (ICA), in intestinal ischemia-reperfusion (I/R) injury and hypoxia-reoxygenation (H/R) injury. METHODS Male Sprague-Dawley rats were pretreated with

Protein tyrosine kinase (PTK) signaling pathways play important roles in ischemia/reperfusion (I/R) or hypoxia/reoxygenation (H/R) injuries. Inhibition of PTK activation can protect against I/R- or H/R-induced damages. As one part of our work for seeking bioactive compounds from natural sources

OBJECTIVE The study the effects of oral administered icariin on intracavernosal pressure (ICP) and on expression of the nitrogen oxide synthase (NOS) isoforms in corpus cavernosum (CC) of arteriogenic erectile dysfunction (A-ED) rat model. METHODS Forty adult male Wistar rats were randomly divided

In this study, we demonstrated that hypoxia/reoxygenation (H/R) induced an injury in gap junctional intercellular communication (GJIC) after 2 h of reoxygenation in cultured HUVEC. Free radical scavenger (DMSO) and antioxidant (SOD) did not prevent this GJIC injury at all. Protein kinase C inhibitor

Icariin has been reported to enhance bone healing and treat osteoporosis. In this study, we examined the detail molecular mechanisms of icariin on lipopolysaccharide (LPS)-induced osteolysis. Our hypothesis is that icariin can inhibit osteoclast differentiation and bone resorption by suppressing
