The most common cause of renal artery stenosis is atherosclerosis, the same condition that causes narrowing of the arteries in coronary heart disease and stroke, and the risk factors are the same as well. Cholesterol plaques build up along the walls of the renal artery and gradually cause narrowing.
Oxytocin is a commonly used uterotonic that can cause significant and even fatal hypotension, particularly when given as a bolus. The resulting hypotension can be produced by a decrease in systemic vascular resistance or cardiac output through a decrease in venous return.
Oxytocin (OT) acts as an important hormone in a human reproductive system and its effects on uterus, ovary, trophoblasts, testis, and prostate glands are already described (Copland et al., 2002 and Thackare et al., 2006).1990) observed that OT has a mitogenic effect on MCF7 cells, and Cassoni et al., 1994 and Cassoni et al., 1997 revealed that it inhibits cell proliferation in MCF7, T47D, and MDA-MB231 cell lines, but Ito et al. (1996) found that it had no effect on the proliferation of breast cancer cells.
