摘要
目的观察3-甲基-1-苯基-2-吡唑啉-5-酮(MCI-186,商品名为依达拉奉)对出血性脑组织的保护作用和可能机制。方法将96只Sprague-Dawley大鼠按随机数字表法分为假手术组、脑出血模型组、依达拉奉治疗组,每组32只。采用自体血脑内注入法制作大鼠脑出血模型,假手术组只进针不注血。依达拉奉治疗组大鼠腹腔注射依达拉奉(3mg/kg),分别于造模前30min及造模后1次/12h。于6、24、72、168h分别用Longa标准测定神经功能缺损;干、湿重法检测脑含水量;酶联免疫吸附法(ELISA)和硫代巴比妥酸法测定血肿周围组织中脑组织TNF-α和丙二醛(malondialde-hyde,MDA)的含量。结果与假手术组相比,脑出血模型组大鼠神经功能缺损评分、脑含水量、TNF-α和MDA含量均显著增高(P<0.05);与脑出血模型组相比,依达拉奉治疗组大鼠神经功能缺损评分、脑含水量、TNF-α和MDA含量显著下降(P<0.05)。结论依达拉奉对出血后脑组织具有保护作用,其机制可能与抑制MDA和TNF-α的活性有关。
Objective To observe the protective effect of edaraven on brain tissue and the therapeutic mechanism in rats following intracerebral hemorrhage(ICH). Methods In this series, 96 Sprague-Dawley rats were divided into three groups at random( n = 32 in each group) : sham-operative group, ICH model group and edaraven therapy group. ICH model was induced by infusion of autologous whole blood into the caudate-putamen. Rats in sham-operative group were treated the same as above, but no blood injected. Rats in edaraven therapy group were treated with edaraven (3 mg/kg) by peritoneal injection 30 min before operation and once per 12 hours after operation. These rats were killed at 6, 24, 72, and 168 h after neurologic impairment test with Longa criteria. Brain water content was measured by dry-wet weight method. Malondialdehyde and TNF-alpha in the vicinity of the hematoma were measured by thio-barbituric acid method and ELISA respectively. Results Compared with sham operative group, neurologic impairment score, brain water content, malondialdehyde and TNF-alpha in brain tissues were obviously higher in ICH model group ( P 〈 0.05 ). Compared with ICH model group, neurologic impairment score, brain water content, malondialdehyde and TNF-alpha in brain tissues were significantly decreased in edaraven therapy group ( P 〈 0.05 ). Conclusion Edaraven has an evident protective effect on injured brain tissue through inhibiting malondialdehyde and TNF-alpha content in the vicinity of the hematoma.
