ABSTRACT
Aim To investigate the effect of ligustrazine on pulmonary arterial pressure,thromboxane A2(TXA2) and prostacyclin(PGI2) in chronic hypoxic hypercapnic rats.Methods Thirty rats were randomly divided into control group(A), hypoxic hypercapnic group(B) and hypoxic hypercapnia+ ligustrazine (lig) group (C) .Results The mPAP in group B was significantly higher than that in group A(P0.05) ; The specific value of WA/TA(vessel wall area/total area) and SMC (the density of medial smooth muscle cells) were significantly higher in group B than that in group A(P0.05).Conclusion Ligustrazine can inhibit pulmonary hypertension and structural remodeling of pulmonary artery in chronic hypoxic hypercapnic rats by inhibiting synthesis of TXA2.
