Ascitic syndrome is one of the main causes of mortality in broilers, being the hypoxia the leading factor to which is added the answer of the organism by liberation of diverse sustances that conduce to the pathologic pattern, such us endotheline 1 (ET-1), nitric oxide (NO), prostaglandins and inflammatory chemokines. The rol of NO in the pulmonary arteriolar hypertrophy and right cardiac hypertrophy observed in ascitic syndrome is still unknown. Hence, the aim of this study was to obtain the values of nitrites and nitrates, stable metabolites of NO, and its correlation with the degree of pulmonary arteriole hypertrophy through the muscular wall/arteriolar diameter (CM/DA) ratio, the right ventricular hypertrophy through the right ventricle/total ventricle (RV/TV) ratio and right ventricle/body weight (RV/BW) ratio in chickens rised at environmental hypoxia. A total of 135 male, Cobb vantres chickens and born at sea level were studied; 15 of them were sacrificed at 1 day age and diverse variables were determinate in their samples whose results were used as comparative base line for those of the other animals. The reminder 120 chickens were distributed in the groups: Sea Level (SL) 60 birds and altitude (A) 60 birds. At 10, 20, 30 and 40 days old, 15 chicken were taken randomly to measure body weight (BW), hematocrite (Ht), nitrites and nitrates, MW/AD, RV/VT and RV/BW.
