The antihemorrhagic shock action and mechanism of fructose 1
6-diphosphate(FDP) were studied on rats. Sixty rats in hemorrhagic shock were randomly divided into three groups( n =20). Treatment group (A) received FDP (250mg/kg) as aqueous solution
and a control group (B) received 5% glucose solution (250mg/kg)
another control group (C) received equal volume of saline in the same manner. 60min after administion
the mean arterial pressure (MAP) of the group a was 10 4±2 1kPa
while those of two control (B、C) were 7 9±2 4 and 7 7±2 6kPa respectively ( P <0 01). Survival rats of groups A
B and C were 75%
25% and 15% respectively ( P <0 01). pH and PaO 2 were reduced from 7 04±0 14 and 13 46±1 22 kPa in group A to 7 14±0 14 and 10 29±3 84 kPa or 7 02±0 10 and 7 25±2 12 kPa in control group B and C ( P <0 01). 30min after retransfusion of the shed blood
serum concentration of SOD and MDA of group A were 1200±126u/ml and 0 47±0 25 nmol/ml
1081±119 u/ml and 0 91+0 29nmol/ml of 835±91μ/ml and 1 13±0 16nmol/ml in control group B and C (all P <0 01) respectively. The results showed that FDP could offectively prevent hemorrhagic shock in blood shed rats.
