Qidantongmai (QDTM) is a Traditional Chinese Medicine (TCM) preparation that has long been used in folk medicine for the treatment of cardiovascular diseases. However, the underlying mechanisms are poorly understood. The present study was designed to determine the effects of QDTM on endothelial cells under hypoxic conditions both in vitro and in vivo. Primary human umbilical vein endothelial ce...

Impaired hemostasis coexists with accelerated atherosclerosis in patients with chronic kidney disease (CKD). The elevated frequency of atherothrombotic events has been associated with endothelial dysfunction. The relative contribution of the uremic state and the impact of the renal replacement therapies have been often disregarded. Plasma markers of endothelial activation and damage were evalua...

The number of the circulating angiogenic cells (CACs) and colony forming units (CFUs) derived from cultured circulating mononuclear cells (MNCs) represents a laboratory surrogate for endothelial cell repair ability. The serum of men with erectile dysfunction (ED) and vascular risk factors (VRFs) showed an increased level of endothelial cell damage/dysfunction markers and reduced the numbers of ...

Hypertension is a major factor that contributes to the development of the vascular complications of diabetes mellitus, which primarily include atherosclerosis, nephropathy, and retinopathy. The mechanism of the pathophyslologkal effects of hypertension lies at the cellular level in the blood vessel wall, which intimately involves the function and interaction of the endothelial and vascular smoo...

Leukocyte-endothelial cell interactions are mediated by various cell adhesion molecules. These interactions are important for leukocyte extravasation and trafficking in all domestic animal species. An initial slowing of leukocytes on the vascular endothelium is mediated by selectins. This event is followed by (1) activation of beta2 integrins after leukocyte exposure to cytokines and pro-inflam...

Background: Hepatic ischemia/reperfusion injury (I/RI) is a multifactorial pathophysiologic process which can lead to liver damage and dysfunction. This study examined the protective effect of dexamethasone on the gene expression of endothelial nitric oxide synthase (eNOS) and endothelin-1 (ET-1) and on the liver tissue damage during warm hepatic I/R. Materials and Methods: A total of 32 mal...

Vascular endothelial damage has been found to be associated with thrombus formation, which is considered to be a risk factor for cardiovascular disease. A diet of natto leads to a low prevalence of cardiovascular disease. The aim of the present study was to investigate the effects of natto extract on vascular endothelia damage with exposure to laser irradiation. Endothelial damage both in vitro...
