Does norepinephrine inhibit the pelvic pressure increase in response to flow perfusion?
Endoluminal administration of norepinephrine caused a dose dependent inhibition on the pressure phases of the pressure flow relationship of the upper urinary tract in pigs. No systemic changes were observed. These observations may provide a useful adjuvant treatment strategy for upper urinary tract stone treatment and endoscopy.
In contrast to two autoimmune diseases, Hashimoto's thyroiditis and Graves' disease, the frequency of vitiligo was not increased among patients with BS. This constitutes further evidence that traditional autoimmune mechanisms may not be operative in BS.
