alpha-, beta 1- and beta 2-adrenergic receptors in the kidney mediate vasoconstriction, renin secretion and vasodilatation, respectively. Blockade of beta-receptors may therefore be expected to influence renal blood flow and possibly glomerular filtration rate by intrarenal effects as well as by reducing cardiac output and blood pressure.
Vampires proper originate in folklore widely reported from Eastern Europe in the late 17th and 18th centuries. These tales formed the basis of the vampire legend that later entered Germany and England, where they were subsequently embellished and popularized.ccording to the paper, if the first vampire had appeared on 1 January 1600, and it fed once a month (which is less often than what is depicted in films and folklore), and every victim turned into a vampire, then within two and a half years the entire human population of the time would have become vampires.
The fictional (made-up) character of Dracula is inspired from bloodthirsty ruler Vlad ÈepeÈ that lived in Romania, Eastern Europe, between 1431 and 1476. His name was originally Vlad III, Prince of Wallachia and Transylvania-middle and southern parts of Romania.he original Vlad Dracula was not a Count, nor was he a vampire. In writing Dracula, Stoker may also have drawn on Gaelic fairy stories about blood-drinking women. The mannerisms of Dracula are thought to have come from a man called Henry Irving, a stage actor in the Victorian era at a theater where Stoker worked.
