AIM: To investigate the effect of low molecular weight heparins (LMWH) on the inhibition of intimal hyperplasia (IH) developing in prosthetic vascular patch graft implanted into sheep carotid artery. METHODS: A gelatin sealed Dacron patch graft was implanted into the common carotid artery of sheep, which were then allocated to a control group (n = 10) or to one of four treatment groups (each group n = 10) receiving either a low dose (LD) or high dose (HD) of one of two LMWH (enoxaparin 1 or 2 mg/kg/day, dalteparin 100 or 200 units/kg/day) administered subcutaneously for 4 weeks. Anti-activated factor X and activated partial thromboplastin time were assayed from blood collected prior to and at 1 and 2 h after LMWH administration on days 3, 7, 14, 21 and 28. Animals were killed on day 28 after taking blood samples prior to, then at 0.5, 1, 2, 3, 4, 6, 8, 12 and 24 h following the last injection. Grafts were collected for analysis and measurements of intimal thickness obtained under light microscopy from eight transverse sections of each grafted artery aided by computer image analysis. An IH index was calculated by dividing the area of IH (mm2) by the width of the graft (mm). RESULTS: Intimal hyperplasia index measurements (mean +/- SD) were: controls 0.574 +/- 0.077, LD enoxaparin 0.471 +/- 0.056, LD dalteparin 0.404 +/- 0.025, HD enoxaparin 0.398 +/- 0.068, HD dalteparin 0.332 +/- 0.048. The reductions in IH index compared to controls were significant (P < 0.05) for both LD and HD dalteparin and for HD enoxaparin. CONCLUSION: Both LMWH dalteparin and enoxaparin reduced the amount of IH formation with dalteparin showing a greater effect in the present animal study. The possibility that different LMWH might exert differing antiproliferative effects requires further investigation. 相似文献

低分子量肝素在血液透析中的应用 总被引:14,自引:0,他引:14
为探讨低分子量肝素在血液透析中的抗凝作用,选择血液透析患者60例、1500例次,分成两组。一组透析中使用肝素抗凝,另一组使用低分子量肝素(CX)抗凝,分别测量凝血时间、凝血酶原时间、活化部分凝血活酶时间及血小板,进行对照研究。结果发现,CX比肝素能更有效地抗凝,又能减少出血倾向,透析器复用次数明显增加,活化部分凝血活酶时间降低(P<0.01)。表明低分子量肝素特别适用于有出血倾向者,可代替肝素在血液透析中应用。 相似文献

SUMMARY: The congenital nephrotic syndrome (CNS) is characterized by severe proteinuria, followed by hypoalbuminaemia and hypercoagulopathy. the boy was born in the 39th gestational week (1980 g bodyweight). In the first days of his life, he developed proteinuria and oedema, and on the 10th day, a thrombosis of the vena cava inferior was diagnosed. the boy was treated with unfractionated heparin, antithrombin concentrates and a low-dose of recombinant tissue plasminogen activator (rtPA). After 2 days, a complete resolution of the thrombus was observed. Treatment with unfractionated heparin and antithrombin III was continued. At the age of 3 months, low molecular weight heparin (LMWH) was started before the patient was discharged. Despite a high dose of LMWH, 250 IU/kg bodyweight, the anti-Xa-activity was always below 0.1 U/mL. Therefore, anticoagulation was achieved by the administration of vitamin K antagonist. Low molecular weight heparin is bound to albumin and antithrombin. Therefore, the renal loss of these proteins may result in low plasma levels of LMWH, and may not be effective in patients with CNS. 相似文献

Effect of low molecular weight heparin on fracture healing in a stabilized rat femur fracture model.
The purpose of this study was to evaluate the effect of low molecular weight heparin (LMWH) on fracture healing in a standard stabilized rat femur fracture model. A closed, mid-diaphyseal transverse fracture was created in the right femur of Long-Evans rats after insertion of a 0.8-mm K-wire into the medullary canal. Animals were randomized to receive either LMWH (70 units/kg dalteparin) or an injection of normal saline daily for 2 weeks. Animals were sacrificed at 2, 3, and 6 weeks. Fracture healing was assessed by radiographs, histology, and mechanical testing. There were no significant differences between the control and LMWH groups in the percentage of animals with radiographic bridging callus at each time point. Histologic appearance of fracture healing was similar between the control and LMWH groups. There were no significant differences in the normalized mechanical properties of the control and LMWH groups at 2 and 3 weeks. At 6 weeks, the percent torque of the LMWH group was significantly greater than the control group ( p = 0.0072), however, there was no significant difference in the stiffness and energy absorption. Dalteparin, at the dosage used in this study, did not impair fracture healing in this standard stabilized rat femur fracture model. 相似文献
