Betamethasone is a synthetic glucocorticoid with anti-inflammatory and immunosuppressive activities. Betamethasone accelerates fetal lung maturation and induces gene expression and apoptosis[1][2][3][4].

体外研究
(In Vitro)

Betamethasone (0.1-1 μM; 12 h) induces gene expression in L929 cells[4].
Betamethasone (0.1-1 μM; 48 h) induces CEM C7 T-cells apoptosis[4].

体内研究
(In Vivo)

Betamethasone (0.48 mg; i.v.gtt for 48 h) decreases the hypercapnia-induced increase in CBF due to decreased cerebral vasodilatation[1]. Betamethasone (0.05 ml (1 mg/L); topical injection) ameliorates spinal nerve transection induced mechanical allodynia and thermal hyperalgesia, and reduces the activation of NF-κB and elevation of TNFα and IL-1β, and induces the expression of IL-10 in the rats brain[2].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Rambouillet-Colombia ewes bred on a single occasion are received hypercapnic challenges[1]
Dosage: 0.48 mg
Administration: Injected into the fetal jugular vein at a rate of 1 ml/h (10 μg betamethasone/h) and maintained over the next 48 h.
Result: Decreased cerebral blood flow (CBF) in all brain regions measured except the hippocampus after 24 h of infusion.
The reduction in CBF was diminished to about 25-30 % after 48 h of infusion.

In Vivo:

请根据您的实验动物和给药方式选择适当的溶解方案。以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：

——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用； 以下溶剂前显示的百
分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

  • 1.

    请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% saline

    Solubility: ≥ 2.5 mg/mL (6.37 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.37 mM，饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。

    将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液

  • 2.

    请依序添加每种溶剂： 10% DMSO    90% (20% SBE-β-CD in saline)

    Solubility: ≥ 2.5 mg/mL (6.37 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.37 mM，饱和度未知) 的澄清溶液。

    以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。

    将 2 g 磺丁基醚 β-环糊精加入 5 mL 生理盐水中，再用生理盐水定容至 10 mL，完全溶解，澄清透明
  • 3.

    请依序添加每种溶剂： 10% DMSO    90% corn oil

    Solubility: ≥ 2.5 mg/mL (6.37 mM); Clear solution

    此方案可获得 ≥ 2.5 mg/mL (6.37 mM，饱和度未知) 的澄清溶液，此方案不适用于实验周期在半个月以上的实验。

    以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。
