Antihypertensive effect of gomisin A from Schisandra chinensis on angiotensin II-induced hypertension via preservation of nitric oxide bioavailability

InvestigacionesPor: Ji Young Park, Jung Wook Yun, Young Whan Choi, Jin Ung Bae, Kyo Won Seo, Seung Jin Lee, So Youn Park, Ki Whan Hong y Chi Dae Kim. Hypertension Research (2012) 35, 928–934.

These alterations in BP, NOS phosphorylation and ROS production in the vasculature of Ang II-treated mice were markedly and dose-dependently reversed by simultaneous administration of GA (2 and 10μg kg−1 per min). In addition, Ang II-induced ROS production in cultured vascular cells such as endothelial cells and vascular smooth muscle cells was markedly attenuated by GA. These results suggested that GA attenuated the increase in BP via preservation of vascular NO bioavailability not only by inhibiting ROS production but also by preventing the impairment of eNOS function in the vasculature of Ang II-induced hypertensive mice.

Lifestyle and metabolic approaches to maximizing erectile and vascular health

Por: D R Meldrum, J C Gambone, M A Morris, K Esposito, D Giugliano y L J Ignarro. International Journal of Impotence Research (2012) 24, 61–68.

El estrés oxidativo y la inflamación, que interrumpen el óxido nítrico (NO) directamente o por causar resistencia a la insulina, son determinantes centrales de las enfermedades vasculares, incluyendo la disfunción eréctil. La – NO vascular reducida – se ha relacionado con la obesidad abdominal, el tabaquismo y el consumo elevado de grasa y azúcar, todos los cuales causan estrés oxidativo.
