Embodiment 1
[0021] Preparation of the drug:
[0022] Mix 20.5 mg of carbon monoxide releasing molecules with 1 ml of DMSO to obtain a 40 mM preparation A, which is used at a dose of 8 mg / kg body weight; mix 20,000 IU / 2 ml of heparin with normal saline and dilute 10 times to obtain 1000 IU / L Heparin solution preparation B is used at a dose of 100IU / kg body weight.
Embodiment 2
[0024] The effects of CORM-2+ ultramicro-dose heparin on WBC, PLT count, plasminogen (PLG) and antithrombin III (AT-III) activities in septic mice.
[0025] experiment method:
[0026] (1) Animal and CLP sepsis models
[0027] Male C57BL / 6 mice, 6-8 weeks old, weighing 18±2 grams, are raised in ordinary laboratories (commercial dry block material, free drinking water). The experimental animals were divided into three groups according to the random number table method: Sham group (n=9), CLP group (n=9) and CLP+CORM-2+heparin group (n=9).
[0028] Under isoflurane inhalation anesthesia, mice in the CLP group underwent cecal ligation and perforation. After injury, 1.5ml normal saline was injected into the abdominal cavity for anti-shock; the mice in the CLP+CORM-2+heparin group were injected with CORM-2(8mg) after CLP. / kg), and at the same time intraperitoneal injection of heparin 100U / kg body weight.
[0029] Among them, the medicine used in the Sham group is normal saline, the medicin...
Embodiment 3
[0050] The effect of CORM-2+ ultra-micro-dose heparin on blood coagulation system and platelet aggregation in septic mice
[0051] experiment method:
[0052] (1) Animal and CLP sepsis models
[0053] Male C57BL / 6 mice, 6-8 weeks old, weighing 18±2 grams, are raised in ordinary laboratories (commercial dry block material, free drinking water). The experimental animals were divided into three groups according to the random number table method: Sham group (n=9), CLP group (n=9) and CLP+CORM-2+heparin group (n=9). Under isoflurane inhalation anesthesia, mice in CLP group underwent cecal ligation and perforation. After injury, 1.5ml normal saline was injected into the abdominal cavity for anti-shock; mice in CLP+CORM-2+heparin group were injected with CORM-2(8mg) after CLP. / kg), and at the same time intraperitoneal injection of heparin 100U / kg body weight. All animals were killed by inhalation of isoflurane 24 hours after injury, and specimens were collected.
