Abstract:
OBJECTIVETo observe the antifebrile effect of Naoreqing (NRQ) oral liquid on secretive function of vaso-endothelial cells in rabbits with endotoxic fever.
METHODSEndotoxic fever rabbit model was duplicated to observe the effects of NRQ on body temperature, blood levels of thromboxane B2 (TXB2), 6-keto-prostaglandin F1alpha (6-keto-PGF1alpha) and endothelin (ET) using radioimmunoassay, as well as activity of tissue-type plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI) in plasma by chromophoric substrate assay.
RESULTSComparisons of various indexes between the two groups showed significantly difference, i.e. the maximal increment of body temperature: 0.69 +/- 0.07 degrees C vs 1.31 +/- 0.13 degrees C (the NRQ treated group vs the untreated model group, the same hereafter); 2h thermal response index TRI2 4.85 +/- 0.57 vs 8.44 +/- 0.98; plasma ET content 197.96 +/- 39.11 ng/L vs 250.80 +/- 40.99 ng/L; TXB2 content 177.35 +/- 77.30 ng/L vs 279.64 +/- 83.74 ng/L; activity of PAI 0.84 +/- 0.01AU/ml vs 0.86 +/- 0.01 AU/ml; plasma 6-keto-PGF1alpha content 986.70 +/- 327.36 ng/L vs 507.81 +/- 170.01 ng/L; activity of t-PA 0.25 +/- 0.02 IU/ml vs 0.21 +/- 0.02 IU/ml (P < 0.05, P < 0.01).
CONCLUSIONNRQ may improve secretive function of vaso-endothelial cells to dilate blood vessel and quicken heat dissipation through body surface, so as to play an integral antipyretic effect in rabbits with endotoxic fever.
