大黄素

The pH effect on the interaction between aloe-emodin and DNA was studied by UV-Vis spectrometry and cyclic voltammetry.

用紫外光谱法和循环伏安法研究了溶液pH值对芦荟大黄素与DNA之间相互作用方式的影响。

The phosphorylation and fragmentation of Bcl-2 have been demonstrated to be involved in cell death. In this study, PDT with aloe-emodin induced simultaneously the phosphorylation and fragmentation of Bcl-2 in H460 cells.

Bcl-2蛋白的磷酸化或断片已被证实与细胞死亡有密切关系，在本研究中，芦荟大黄素配合光照会引发Bcl-2蛋白同时产生磷酸化及断片的现象。

The response of the sensor to hybridization temperature and the specificity, reproducibility and sensitivity of the sensor were investigatied using Aloe-emodin as an electroactive indicator.

以电活性的芦荟大黄素为杂交指示剂，考察了杂交温度及传感器的特异性、重现性和检出限等性能。

Aloe-emodin blocks PHA-induced proliferation of T lymphocytes and the mechanism for this may be due to its inhibition on PHA-induced [Ca_(2 )]_imobilization.

结论芦荟大黄素可抑制T淋巴细胞增殖，其作用机制可能与抑制淋巴细胞内[Ca2 ]i升高相关。

These results suggest that aloe-emodin induced apoptosis and inhibited invasion in PSC cells were mediated through mitochondria dependent and Ras-MAPK pathways. It implies the possibility that

以上结果说明了芦荟大黄素可能作为一种有效治疗舌咽癌细胞的抗癌药物。

Physcion also showed good protective and therapeutic effects against cucumber powdery mildew in greenhouse test.

盆栽试验结果也表明大黄素甲醚对黄瓜白粉病菌具有良好的保护和治疗效果。

RESULTS: Isorhapotigenin and resveratrol, at the concentrations of 2×10-6 and 2×10-5 mol?

结果：异丹叶大黄素和白藜芦醇在2×10-6和2×10-5 mol？

It is proposed that the emodin inhibited TMV by binding to TMV virions to interfere with recognition of a host receptor essential for infection.

上述结果表明大黄素的抑制作用可能是与病毒粒体结合影响病毒对叶片侵染位点的识别。

The emodin did not inhibited multiplication of TMV in infected leaf discs or infectivity of TMV-RNA in vitro. The infectivity of TMV recovered by dialysis from incubations with emodin in vitro has regained showed that the emodin did not direct viricidal effect. The emodin did not reduce infectivity of TMV when applied before TMV inoculation.

大黄素对粒体无形态破坏作用，与TMV混合后经过透析可恢复大部分的侵染活性，体外混合不影响TMV-RNA的侵染活性，并无体内抑制复制作用，预先接种也不影响TMV随后的侵染。
