The Effects of Inhalation of Aerosolized Low Molecular Weight Heparin on the Clotting Time in Guinea Pigs and Bleeding Time in Mice / 中国药房

AIM:To study the effects of inhalation of aerosolized low molecular weight heparin(LMWH)and standard heparin(SH) on the clotting time and bleeding time in guinea pigs and mice.METHODS:Guinea-pigs and mice inhaled aersolized LMWH and SH for 7 days,and the clotting time in guinea-pigs and tail bleeding time in mice were observed.RESULTS:Compared with vehicle,LMWH 800IU/L,400IU/L and SH 800IU/L,400IU/L had no significant effects on the clotting time in guinea-pigs and tail bleeding time in mice(P>0.05);There were no significant differences between LMWH 800IU/L,400IU/L and SH 800IU/L,400IU/L(P>0.05).CONCLUSION:Inhalation of aerosolized LMWH and SH had no significant effects on clotting time and bleeding time in animals.
