title: [Correlation between TXB2, 6-Keto-PGF1alpha and liver metastasis in rats model with blood stasis].
abstract: OBJECTIVE
  To observe the correlation between serum level of TXB2, 6-Keto-PGF1alpha and liver metastasis.
  
  
  METHODS
  The metastatic model was made by injection of W256 carcinosarcoma. Rats were randomly divided into two groups: rats with blood stasis group and control group. Rats in control group were given normal saline via abdominal cavity once a day. Rats in blood stasis group were injected adrenalin in the fourteenth day. Tumor size and liver metastasis were observed. Serum TXB2 and 6-Keto-PGF1alpha were tested by radioimmunoassay.
  
  
  RESULTS
  Tumor size in rats with blood stasis was significantly smaller than that of the control group (P<0.01). Occurrence of liver metastasis in rats with blood stasis was significantly lower than that of the control group (P<0.01). The values of 6-Keto-PGF1alpha, TXB2, and TXB2/6-Keto-PGF1alpha were higher in the group with blood stasis.
  
  
  CONCLUSIONS
  In the status of blood stasis, W256 carcinosarcoma grows slowly, and liver metastasis increases insignificantly, with the elevations of 6-Keto-PGF1alpha, TXB2 and TXB2/6-Keto-PGF1alpha.
