The staining of F-actin in the ischemia reperfusion group was decreased significantly （P.05） compared with the normal control group. There was a marked loss of canalicular microvilli and distension of canalicular lumen in the ischemia reperfusion group. The staining of F-actin in the LA group was significantly increased than those in the I/R group （P.05）. Conclusions: Ischemia reperfusion induces an disruption of bile canalicular F-actin microfilaments and a loss of microvilli. Alpha-lipoic acid can protect bile canalicular F-actin microfilaments against IRI.

肝脏I/R可造成胆小管F-actin微丝破坏、微绒毛丧失，导致胆小管收缩减弱，胆汁排泄功能受损，这可能是大鼠肝脏I/ R后缺血型胆道病变发生的主要机制；α-硫辛酸通过清除氧自由基，降低脂质过氧化反应，调节细胞内氧化剂-抗氧化剂的含量，保护胆小管F-actin微丝结构免遭缺血再灌注损伤破坏，进而预防和治疗缺血型胆道病变。

The stabilities of the extract from sanguisorba under different pH, light, heat, ultraviolet ray, oxidant, reducing agent and additive agents were studied. It was indicated the products could widely used in the condition of weak acid or neutral, while they were not stable to heat and light, so they should be used without light and at low temperature. The products had a strong ability to withstand ultraviolet ray. They could easily be oxidized and degraded by oxidant while they were not easily affected by reducing agent and were almost not affected by additive agents. The extract from the stem of sanguisorba was analyzed by UV and FTIR, showing that the structures of the active components were not changed during ultrasonic wave extracting.

研究了pH值、光、热、紫外线、氧化剂、还原剂以及添加剂对地榆提取物稳定性的影响，结果表明地榆提取物适合弱酸或中性条件下使用，使用范围比较广；但对光热稳定性较差，适合在避光低温的环境；具有很强的抗紫外线能力；氧化剂对地榆提取物稳定性影响较大，会加速其降解，还原剂对地榆提取物影响不大；其他添加剂对其稳定性几乎没有影响；并通过UV和FTIR光谱分析，超声波浸提没有对地榆根茎中有效成分的结构发生改变。
