一般建议 | 为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同厂家不同批次产品溶解度各有差异,仅做参考。若实验所需浓度过大至产品溶解极限,请添加助溶剂助溶或自行调整浓度。溶液形式一般不宜长期储存,请尽快用完。 |
Sodium tauroursodeoxycholate (TUDC) 对胆汁淤积具有治疗效果[1,2]。在人红细胞中,它抑制胆汁盐诱导的2’,7’-bis-(carboxypropyl)-5(6)-carboxyfluorescein (BCPCF)外流,IC50值为560 μM [3]。
胆汁淤积是胆汁生成障碍所引起的病症,胆汁生成具有重要作用[4]。
cVA-of-CLF意味着 cholyllysylfluorescein的小管空泡累积[1]。CLF的cVA是总胆汁分泌参数[5]。用17βEG培养会剂量依赖性的减少细胞的cVA-of-CLF。50 μM浓度的17βEG使cVA-of-CLF下降40%。同时用TUDC和17βEG培养将cVA 的下降改善24%。同时用SAMe和17βEG培养将cVA 的下降改善18%。与TUDC相比,同时用TUDC、17βEG和SAMe培养将cVA 的下降改善28%。但是TUDC和SAMe的共同效果并不比任何保护剂的单独效果显著[1]。
在大鼠中,腹腔给药500 μg/kg的毒伞素7天,引起肝内胆汁淤积。在这些给药大鼠中,胆汁流量减少,谷丙转氨酶、亮氨酸氨肽酶、血清碱性磷酸酶的活性以及胆汁酸、磷脂和胆固醇的浓度升高。但是,tauroursodeoxycholate显著抑制这些效应。在这些大鼠中,tauroursodeoxycholate显著地改善了胆汁胆固醇和磷脂的排泄率[2]。
