    ABSTRACT: To compare the effect of the extracts from Decoction for resuscitation (DRE) and its component herbs on prostacyclin (PGI2), thromboxane A2 (TXA2) and nitric oxide (NO) release from rat vascular endothelial cells under hypoxia. After treatment with the extracts from DRE and its component herbs, the contents of 6-keto-prostaglandin F1alpha(6-keto-PGF1alpha), thromboxane B2 (TXB2) as well as nitrite (NO), which were degradation products of PGI2, TXA2 and NO respectively, in culture medium of rat vascular endothelial cells under hypoxia were measured with radioimmunoassay and Griess Reaction. Compared with the control group, the results indicated that DRE, prepared licorice root extract (LE), dried ginger extract (GE), aconite root extract (AE), extracts of aconite root and prepared licorice root (ALE), extracts of aconite root and dried ginger (AGE) increased significantly the content of 6-keto-PGF1alpha and the ratio of 6-keto-PGF1alpha/TXB2, but had no effect on the content of TXB2 in culture medium of rat vascular endothelial cells under hypoxia. The content of 6-keto-PGF1alpha in the DRE group was higher than that in the groups of LE, GE, AE, ALE, AGE. The ratio of 6-keto-PGF1alpha/TXB2 in the DRE group was higher than that of the groups of GE, AE, ALE. Compared with the control group, DRE, LE, GE, AE, ALE, AGE increased significantly the content of NO2- in culture medium of rat vascular endothelial cells under hypoxia. Moreover, the content of NO2- in the DRE group was higher than that of the groups of GE, AE, ALE. The results suggested that DRE increased significantly the content of PGI2 and the ratio of PGI2/TXA2 as well as the content of NO. The effect of DRE on the parameters in culture medium of rat vascular endothelial cells under hypoxia was better than that of the extracts from its component herbs.
