Red blood cell endothelial cells. Exposure of red blood cells to physiological levels of shear stress activates nitric oxide synthase and export of nitric oxide, which may contribute to the regulation of vascular tonus. Red blood cells can also produce hydrogen sulfide, a signalling gas that acts to relax vessel walls. It is believed that the cardioprotective effects of garlic are due to red blood cells converting its sulfur compounds into hydrogen sulfide. Red blood cells also play a part in the body's immune response: when lysed by pathogens such as bacteria, their hemoglobin releases free radicals, which break down the pathogen's cell
Blood Red Sandman Blood Red Sandman "Blood Red Sandman" is the second single from Lordi's second album "The Monsterican Dream". The song's original title was "Blood Red Santa", but Asko Kallonen from BMG Finland thought it was inappropriate for a Christmas hit and many people said they would ban it because it painted a violent image of Santa. In a rebuttal to this Lordi decided to change the songs name to Blood Red Sandman which worked just as well as the original name. There is also a promo version given out by Mayan Records for promotion to their compilation album The Monster Show.
