請幫忙翻譯一下英文段落

Recently, we have shown that cocaine induced an increase in oxidative stress markers in the prefrontal cortex and nucleus accumbens both in slices and in vivo, and that this increase was completely abolished by treatment with the antioxidant Tempol.Furthermore, rats treated with Tempol showed attenuation of both development and expression of cocaine psychomotor sensitization

Here we used PC12 cells as an in vitro system to study the molecular mechanism by which antioxidants such as Tempol, can reduce cocaine-induced toxicity through oxidative stress. Therefore,cocaine was used to induce cell death in PC12 cells. Oxidative stress was evaluated by specific fluorescence probes, indicating mitochondrial superoxide radical formation (MitoSox Red©) and peroxide generation (H2DCF-DA©). The antioxidant Tempol, a free radical scavenger and superoxide dismutase mimic compound, was used to identify and establish the contribution of exogenous antioxidant treatment against cocaine-induced cell death and oxidative stress.

請各位大大不要用google翻譯後直接解答 小弟翻過了 意思會變很奇怪而且不通順 請英文高手幫忙翻譯一下 謝謝 小弟英文程度差~"~

已更新項目:

可以在幫忙翻譯一下這段嗎? 我翻起來自己覺得好奇怪 謝謝

2 個已更新項目:

In the present study we utilized the well established PC12 cell line system. PC12 cells, a clonal rat pheochromocytoma cell line, have frequently been used as a model for dopaminergic

neurons and many studies have shown that these cells synthesize dopamine and express dopamine receptors.

3 個已更新項目:

Cocaine has already been demonstrated to interfere with uptake and extracellular dopamine levels in PC12 cells. It was shown that cocaine treatment increased extracellular dopamine accumulation in PC12 cells.

4 個已更新項目:

Moreover, it was also shown that in the presence of cocaine intracellular dopamine levels dedecline. In addition, PC12 cells have been extensively used as a model for studying the survival of neuronal cells and the protective role of antioxidants under different pathological conditions. 麻煩您了 謝謝

    最近我們證明了無論在切片實驗或活體實驗,古柯鹼均會造成前額葉皮層與阿控伯核(伏隔核)的氧化壓力指標上升;若再施以抗氧化劑Tempol,則可使抗氧化指標完全降回原始狀態。

    此外,老鼠實驗顯示Tempol降低了古柯鹼造成的亢奮,並減緩亢奮的發展。

    我們於本篇報告中使用了PC12細胞進行體外實驗,透過測量氧化壓力,以研究抗氧化劑(如Tempol)如何降低古柯鹼毒性。

    因此,我們在實驗中將用古柯鹼促使PC12細胞死亡。我們用特定的螢光探針量測粒線體的超氧化自由基生成狀況 (所用儀器為MitoSox Red©),並測量過氧化物的生成量 (所用儀器為H2DCF-DA©),並藉此二指標推算氧化壓力。

    抗氧化劑Tempol是一種自由基清除者,並且他有類似超氧化物歧化酶的作用,我們以Tempol來研究添加外部抗氧化劑對降低古柯鹼促成的死亡及降低氧化壓力之效果。
