- Male SD rats were intraperitoneally injected with 10% chloral hydrate The solution was administered at a dose of 400 mg/kg body weight.
- a longitudinal incision was made in the middle of the neck to separate the trunk of the right common carotid artery (about 3 cm long).
- the branches of the external carotid artery were ligated at the level of the hyoid bone, and the internal carotid artery was separated at the neck enlargement.
- the non-invasive arterial clip was used to clamp the opening of the internal carotid artery and the proximal end of the common carotid artery, and the distal end of the external carotid artery was ligated.
- a catheter containing 0.5 mL of thrombus saline suspension was inserted into the trunk of the external carotid artery. While releasing the internal carotid artery clamp, the 0.5 mL thrombus physiological saline suspension in the catheter was slowly moved from the external carotid artery to the proximal heart. The end is injected into the middle cerebral artery through the internal carotid artery.
- the proximal end of the external carotid artery was ligated, and the arterial clip at the internal carotid artery and the common carotid artery was opened to restore blood flow and suture the wound. And intramuscular injection of 20,000 IU of penicillin to prevent infection.
- 0 points means no signs of neurological deficit
- 1 point means that the uninjured side of the forelimb can not stretch
- 2 points means walking to the uninjured side
- 3 points means turning to the uninjured side to form a trailing trail
- 4 points means that the consciousness is not autonomous walking.
- 5 points indicate death.
- the test results are shown in Table 13. The results showed that after 24 hours of stroke in rats, 1 died, the remaining 10 received 1 dose of 5 mol/kg 5Ak per day, 6 consecutive treatments, no death, 7 improved to no signs of neurological deficit, Three residual signs of neurological deficit remained. It can be seen that at the dose of 5 mol/kg, 5Ak has a definite therapeutic effect on stroke for 24 hours, which is significantly better than the dose of 2.5 ⁇ /kg.
- the compound of the present invention can form a nanostructure and achieve the effect of crossing the blood-brain barrier; in addition to hemolysis and antithrombotic, it can effectively remove free radicals such as OH, NO and superoxide anion; That is, it can effectively dissolve thrombus, and at a slightly higher dose, it can show excellent curative effect on strokes of more than 4 hours, and has good clinical application prospects.
