However, we noted that FVCO and 1HVCO did not cause
significant increase in BP. In the present study, the increase in
BP in 5HVCO and 10HVCO groups was associated with a significant
increase in the plasma, ICAM, VCAM, CRP and
TXB2 levels and a significant decrease in PGI2. The strong positive
correlation between BP changes with ICAM, VCAM,
CRP and TXB2 suggesting that vascular inflammation may
play an important role in BP raising effect of VCO. TXA2 is
a potent pro-aggregator and vasoconstrictor prostanoid. It is
produced and released by the platelets during aggregation
and is rapidly metabolized to its stable breakdown product,
thromboxane B2 (TXB2)25 whilst PGI2 produce vasodilation.
The homoeostasis of TXA2 and PGI2 is crucial for the BP regulation.
Our finding was similar to previous studies which reported
that the release of TXB2 and prostacyclin were
