The effects of tetramethylprazine on pancreatic blood flow in acute pancreatitis in rats and its therapy / 中国药理学通报

ABSTRACT

The effects of tetramethylpy-razine (TMP) on pancreatic blood flow and survival rate were studied in sodium tarocholate-in-duced acute pancreatitis (AP) in rats. The results showed that pancreatic relative blood flow and pancreatic tissue perfusion were significantly increased and the pathologic changes and survival rate were improved in TMP treated group-s. Plasma value of TXB2?6-Keto-PGF1? and platelet aggregation rate (PAR) were also mea-sured. We found that TMP could maintain the balance between TXA2 and PGI2 and lower the elevated PAR. It was suggested that TMP has therapeutic effect on AP in rats through improving pancreatic microcirculation; which was related to the maintanance of the balance between PGI2 and TXA2.
