venom of Trimeresurus albolabris can increase
fibrinolytic activity by shortening euglobulin
time (Kamnerdnond and Jitprommeta, 2004).
A recent report (Rojnuckarin et al, 1999) studied
a group of patients bitten by the green pit
viper (Trimeresurus albolabris and Trimeresurus
macrops). The study found fibrinolytic
system activation was very common as indicated
by low plasminogen, low antiplasmin
and elevated fibrin-fibrinogen degradation
products levels (FDPs ). A significant decrease
in total platelet count and mean platelet volume
(MPV) was demonstrated in envenomated
blood. The changes may have been partly due
to the effect of green pit viper venom on platelet
morphology (Soogarun et al, 2003). In this
study we evaluated the in vitro effect of mixing
green pit viper venom and platelet rich
solution, then observed the changes in morphology
by SEM.
