PURPOSE This study was performed to examine the effect of hypercholesterolemia on inducible nitric oxide synthase (NOS-2) expression and oxidative tissue injury in an experimental rat model of elevated IOP. METHODS Wistar rats were maintained on either regular chow or a high-cholesterol diet for 24 weeks. Intraocular pressure (IOP) was elevated in hypercholesterolemic rats by unilaterally cau...

Hypercholesteremia is one of the risk factors for coronary artery disease. The present study highlights the efficacy of the ayurvedic herbal formulation Arborium Plus [Hyppophae ramnoides L. fruit juice (S) and Rhododendron arboreum Sm. Linn flower juice (R) in a 1:4 ratio] on triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), atherogenic index (AI), high-density lipopro...

INTRODUCTION AND OBJECTIVES In our laboratory, we recently obtained evidence that cultured bovine endothelial cells contain cytosolic proteins that form complexes with the 3'-unstranslated region of endothelial nitric oxide synthase (eNOS) mRNA and are associated with its destabilization. The aim of this study was to determine the presence of such proteins and the level of eNOS expression in hy...

Hypercholesterolemia is one of the most important risk factors for erectile dysfunction, mostly due to the impairment of oxidative stress and endothelial function in the penis. The cannabinoid system might regulate peripheral mechanisms of sexual function; however, its role is still poorly understood. We investigated the effects of CB2 activation on oxidative stress and fibrosis within the corp...

BACKGROUND Red yeast rice (RYR) is a fermented product used as a food supplement to promote blood circulation and lower blood cholesterol levels in eastern Asia. Interestingly, monacolin K is the most active compound in RYR that proved to inhibit HMG-CoA reductase in the cholesterol biosynthesis pathway. METHODS The hypocholesterolemic effects of oral administration of Thai RYR, produced by f...

Lecithin:cholesterol acyltransferase (LCAT), the major cholesterol esterifying enzyme in plasma, plays an important role in the removal of cholesterol from peripheral tissues. This study in rat focuses upon the effects of hypothyroidism and cholesterol feeding on serum activity and hepatic LCAT secretion. To obviate the effect that inclusion of high concentrations of cholesterol in the rat seru...

Cardiovascular diseases continue to be a leading cause of morbidity and mortality in developed as well as developing countries. Hypercholesterolemia is one of the factors that have contributed in acceleration of Coronary Heart Diseases in India. It is associated with elevated lipid levels in the blood. Treatment of hypercholesterolemia is one of the major approaches towards decelerating the ath...

Various cellulose and dextran anion exchangers bind bile salts in vitro under conditions of pH and ionic strength resembling those in the lumen of the small intestine. Of these substances, diethylaminoethyl (DEAE) cellulose, guanidoethyl cellulose, and DEAE Sephadex reduced hypercholesterolemia when added to the diet of cholesterol-fed cockerels. In addition, DEAE Sephadex reduced serum sterols...
