通透系数

氯化铬和吡啶羧酸铬从肠腔侧（AP侧）到基底侧（BL侧）的表观通透系数（Papp）近似于BL侧到AP侧（分别为0.95～1.41倍和0.84～1.07倍）。

The apparent permeability coefficient ( Papp ) of chromium chloride and chromium picolinate from apical to basolateral was similar to that from basolateral to apical ( 0.95-1.41 fold and 0.84-1.07 fold respectively ) .

结果给予不同剂量的丹参酮ⅡA，其表观通透系数Papp随浓度的增加先降低后升高；

RESULTS With the increasing of tanshinone ⅱ A concentration , the apparent permeability coefficient ( Papp ) decresed at first then increased .

实验组Ⅱ、Ⅲ、ⅣBALF中总蛋白浓度、肺湿干重比、肺毛细血管通透系数与对照组相比显著升高（P<005）；

The parameters : total protein concentration of BALF , wet / dry ratio , and the blood capillary permeability of lung , raised strikingly in group ⅱ,ⅲ and ⅳ compared with control group respectively ( P < 0 05 ) .
