Effects Of Nitric Oxide On The Formation Of Pulmonary Hypertension In Broilers And Its Mechanism

Pulmonary hypertension syndrome in broilers was induced by twoways: high sodium concentration in drinking water and low temperature coped with 1.5 ppm 3,3,5-triiodothyronine (T3) supplemented dietary, and effect of nitric oxide (NO) on pulmonary arterial pressure and ascites morbidity in broilers were observed. The experimental results were as following: In experiment 1, high sodium concentration in drinking water increased mean pulmonary arterial pressure (mPAP) , Sodium Nitroprusside (SNP), a kind of donor of NO, intravenously infusion reduced mPAP from 25.96 ?2.96 mmHg to 18.39?.69 mmHg (p
