细胞系 | primary mesencephalic cell |
方法 | To investigate the effect of rotigotine (UCB, Belgium) on the survival of THir neurons, primary mesencephalic cell cultures were treated with different concentrations of rotigotine (0.01, 0.1, 1 and 10 μM) from the 6th DIV for 8 consecutive days. Rotigotine was added with each change of the culture medium every second day from a fresh stock solution (10 mM) prepared in DMSO (0.1% final concentration). To investigate the effect of rotigotine against MPP+ or rotenone-induced cell death, rotigotine was added from the 6th DIV until the 14th DIV as described above and MPP+ (10 μM) or rotenone (20 nM) were co-administered on the 12th DIV for 48 h. |

不同实验动物依据体表面积的等效剂量转换表(数据来源于FDA指南)
| 小鼠 | 大鼠 | 兔 | 豚鼠 | 仓鼠 | 狗 |
重量 (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
体表面积 (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
Km系数 | 3 | 6 | 12 | 8 | 5 | 20 |
动物 A (mg/kg) = 动物 B (mg/kg) × | 动物 B的Km系数 |
动物 A的Km系数 |
例如,依据体表面积折算法,将化合物用于小鼠的剂量20 mg/kg 换算成大鼠的剂量,需要将20 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到化合物用于大鼠的等效剂量为10 mg/kg。
