体外肝素对血浆PT、APTT影响因素的研究及临床应用

目的:探讨体外不同浓度肝素及不同浓度硫酸鱼精蛋白对血浆凝血酶原时间(PT)、活化的部分凝血活酶时间(APTT)的影响,了解该实验对PT、APTT真实结果及正确分析和判断.方法:采用0.1 U/mL～2.0 U/mL肝素,1.0 μg/mL～20 μg/ mL硫酸鱼精蛋白,测定240份随机标本分成的各组血浆标本的PT、APTT及加入上述试剂后的PT、APTT时间. 结果:肝素活性在2.0 U/mL以下时对PT无明显影响,硫酸鱼精蛋白在10 μg/mL以下时对PT、APTT亦无明显影响.肝素在0.2 U/mL时对APTT影响非常明显,两者呈相关(r=0.98,P<0.05). 讨论:临床上可采用回归方程△APTT=1.22+30.41A(A为肝素活性U/mL)回归方法验证,也可以用加硫酸鱼精蛋白中和后复测APTT的方法来纠正肝素对APTT的影响,对DIC的动态监测及治疗具有重要意义.

鞘内注射吗啡加可乐定对切口痛大鼠脊髓背角蛋白激酶A催化亚单位表达的影响

Objective To observe the effect of intrathecal clonidine plus morphine on expression of protein kinase A (PKA) catalytic subunit in the spinal dorsal horn in a rat model of incisional pain. Methods Eighty male Sprague-Dawley rats were divided randomly into five groups: sham group, control group, pre-incisional morphine 2.5 μg group, pro-incisional clonidine 5 μg group and preincisional morphine 2.5 μg plus clonidine 5 lag group (n=16). lntrathecal catheter and the model of incisional pain were pro-duced according to Yaksh and Brennan's described method respectively. Changes of pain behavior were assessed by mechanical with-drawal threshold (MWT) and thermal withdrawal latency(TWL). The expressions of PKA catalytic subunit in the spinal dorsal horn were assessed by immunohistochemical method and western blotting analysis. Results Compared with sham group, MWT and TWL in control group were decreased significantly at 2 h after incision (P<0.01) and the number of positive cells and protein expression of PKA catalytic subunit in the spinal dorsal horn were increased significantly in control group (P<0.01). Compared with control group, MWT and TWL in pre-incision morphine 2 μg plus clonidine 5 lag group were increased significantly at 2 h after incision (P<0.01) and the number of positive cells and protein expression of PKA catalytic subunit in the spinal dorsal horn were decreased significantly in pre-incision morphine 2 μg plus clonidine 5 μg group (P<0.01). However, MWT, TWL and the number of positive cells and pro-tein expression of PKA catalytic subunit in the spinal dorsal horn changed with no statistical significance in pre-incisional morphine 2.5 μg group and pre-incisional clonidine 5 μg group compared with control group. Conclusion lntrathecal clonidine significantly enhances the antinociceptive effect of intrathecal morphine in a rat model of incisional pain, which might be associated with inhibi-tion of the increased expression of PKA catalytic subunit in spinal cord.
