【摘要】：目的：觀察蛛網(wǎng)膜下腔出血（subarachnoid hemorrhage，SAH）后早期大鼠海馬鐵含量及鐵調(diào)素（Hepcidin）蛋白的表達變化，探討鐵調(diào)素參與SAH后早期腦鐵代謝紊亂的可能機制。 方法：成年雄性SD大鼠90只，隨機分為假手術(shù)對照組，實驗組(蛛網(wǎng)膜下腔出血組)。采用視交叉前池注血法構(gòu)造大鼠SAH模型。在SAH后早期12、24、48、72h采用免疫組化、Western-blot法檢測大鼠SAH后海馬組織內(nèi)Hepc的蛋白表達情況，使用原子吸收光譜儀對海馬組織總鐵含量進行檢測。 結(jié)果：免疫組化實驗結(jié)果發(fā)現(xiàn)，，相對于假手術(shù)對照組（0.190.05），大鼠SAH后12h見Hepcidin表達水平明顯增高（0.300.06）,至72h呈逐漸增高趨勢（0.560.07），差異有統(tǒng)計學(xué)意義（F=31.911，P㩳0.05）；Western blot實驗同樣發(fā)現(xiàn)，與假手術(shù)（對照）比較（0.238 0.047），大鼠SAH后12h見Hepcidin蛋白表達水平明顯增高（0.481 0.065）,至72h呈逐漸增高趨勢（1.6270.143），差異有統(tǒng)計學(xué)意義（F=147.314，P㩳0.05）；原子吸收光譜儀在蛛網(wǎng)膜下腔出血后12h檢測到大鼠海馬總鐵含量開始增加（58.509.19），至72h呈逐漸增高趨勢（99.347.68），與假手術(shù)對照組比較（43.514.59），差異有統(tǒng)計學(xué)意義（F=28.799,P㩳0.05）；大鼠海馬組織Hepcidin蛋白的表達量與海馬鐵含量成正相關(guān)（r=0.914，P0.05）。結(jié)論：大鼠SAH后腦鐵含量的增加可能與Hepcidin表達增高有關(guān)。
[Abstract]:Aim: to observe the changes of iron content in hippocampus and the expression of iron modulin (hepcidin) protein in hippocampus of rats with subarachnoid hemorrhage (SAH) after subarachnoid hemorrhage (SAH), and to explore the possible mechanism of iron modulin involved in early brain iron metabolism disorder after SAH. Methods: 90 adult male SD rats were randomly divided into sham operation control group and experimental group (subarachnoid hemorrhage group). The rat SAH model was constructed by injecting blood into the anterior cistern of optic chiasma. The expression of Hepc protein in hippocampus of rats with SAH was detected by immunohistochemistry at 12: 24, 48 and 72 hours after SAH, and the total iron content of hippocampus was detected by atomic absorption spectrometer (AAS). Results: compared with the sham-operated control group (0.190.05), the expression of Hepcidin increased significantly 12 hours after SAH, and gradually increased to 0.560.07 at 72 h after SAH. The difference was statistically significant. Compared with sham-operated (control) 0.238 The expression of Hepcidin protein was significantly increased in rats 12 hours after SAH. The content of total iron in hippocampus of rats was detected by atomic absorption spectrometer at 12 hours after subarachnoid hemorrhage, and the total iron content in hippocampus of rats began to increase by 58.509.19 and 99.347.68% at 72 hours, which was significantly higher than that of sham operation control group (P < 0.05). The content of total iron in hippocampus of rats was increased gradually at 72 h after SAH by atomic absorption spectrometer (AAS), and the content of total iron in hippocampus of rats was increased by atomic absorption spectrometer (AAS) at 12 hours after subarachnoid hemorrhage. Compared with 43.514.59, the difference was statistically significant, and the expression of Hepcidin protein in rat hippocampus was positively correlated with the content of iron in hippocampus. Conclusion: the increase of brain iron content after SAH may be related to the increase of Hepcidin expression.
