体外研究
(In Vitro)

为确定 Citicoline 和高牛磺酸的潜在神经保护活性,将经处理的视网膜细胞用增加浓度的 Citicoline 或高牛磺酸处理 24 小时。1 μM、10 μM 和 100 μM Citicoline 或高牛磺酸用于研究是否会导致视网膜细胞活力降低。视网膜细胞在 Citicoline 或高牛磺酸处理的培养物中保存完好,没有证据表明处理后有毒性或显著丧失生存能力。100 μM Citicoline 在体外对视网膜神经胶质细胞无害,100 μM 高牛磺酸是增强实验性青光眼模型神经保护的有效浓度。因此,此浓度的 Citicoline 和高牛磺酸用于所有后续实验。为了评估 Citicoline 和高牛磺酸的共同处理是否能够诱导针对谷氨酸兴奋性毒性的协同神经保护作用,在谷氨酸处理前 24 小时,将视网膜细胞培养物暴露于 100 μM Citicoline、100 μM 高牛磺酸和 100 μM Citicoline+高牛磺酸。在 100 μM Citicoline存在下,观察到细胞活力显著增加[1]

体内研究
(In Vivo)

以 1000 mg/kg 的剂量施用 Citicoline 会导致阵挛性癫痫发作的阈值和具有致死结果的癫痫发作的强直期更显著增加 (与对照组相比,分别增加 18.54% 和 50.08%)。注射Citicoline 1000 mg/kg 后,抗惊厥作用最为明显[2]

Cell Assay
[1]

The assay used to assess cell viability in retinal cells was the MTT reduction assay. To evaluate the effect of Citicoline and Homotaurine on cell survival, the cells are subdivided into three groups and treated for 24 hours with 1 μM, 10 μM, and 100 μM of Citicoline and with 1 μM, 10 μM and 100 μM of Homotaurine. To evaluate the neuroprotective effects of Citicoline and Homotaurine, cells are treated with Citicoline 100 μM, Homotaurine 100 μM, or Citicoline+Homotaurine 100 μM, 24 hours before glutamate treatment and 30 min before high glucose (HG) treatment. MTT is added to wells at a final concentration of 0.5 mg/mL for 1 hour at 37°C. After this time, the medium is removed and reduced MTT (blue formazan product) is solubilized by adding 100 μL DMSO to each well. After agitation of plates for 15 min, the optical density of the solubilized formazan product in each well is measured using an automatic microplate reader with a 570 nm test wavelength and a 690 nm reference wavelength[1].

Animal Administration
[1]

Mice[1]
Experiments are performed on male C57Bl/6 mice (n=69) weighing 23-27 g. The study is performed in two series. In series I, the dose-dependent effect of Citicoline on the seizure threshold in mice is evaluated. The measurements are performed 1 h after Citicoline administration. Citicoline in doses of 500 and 1000 mg/kg (0.04 mL per 20 g body weight) is injected intraperitoneally. The control animals receive an equivalent volume of physiological saline under similar conditions. In series II, the duration of Citicoline effect is estimated in 3 and 6 h after single intraperitoneal injection of Citicoline.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
