Cell experiment: |
Nasal mucosa and polyp epithelial cells are stimulated with fetal bovine serum (FBS) with or without MK for 24 hours, and cytokine concentrations in epithelial secretions are measured by ELISA. After incubating peripheral blood eosinophils with epithelial cell-conditioned media (ECM) with or without montelukast up to 3 days, eosinophil survival is assessed by Trypan blue dye exclusion[1]. |
|
Animal experiment: |
Rats: Twenty four Sprague Dawley rats are randomLy divided into control group, asthma, and montelukast group. A rat model of asthma is induced by ovalbumin (OVA) inhalation. Normal saline is used instead of sensitizing solution and 1% OVA in the control group. Each rat in the montelukast group is given montelukast (15mg/kg) by gavage 2h before OVA inhalation. All rats are treated for 8 weeks[3]. Mice: Montelukast is dissolved in 0.5% sodium carboxymethyl cellulose (CMC-Na). Mice are randomLy assigned to 4 groups: (1) vehicle plus vehicle,(2) Aβ1-42 plus vehicle, (3) Aβ1-42 plus montelukast (1.0 mg/kg), (4) Aβ1-42 plus montelukast (2.0 mg/kg). The solutions are injected bilaterally into the cerebroventricles through the micropipette[4]. |

Montelukast Sodium (MK-0476) is a selective, reversible antagonist of leukotriene receptor with the Ki values of 0.52nM in U937 cell [1].
Montelukast Sodium has been reported to inhibit leukotriene D4 receptor specific binding in U937 cell, guinea pig lung and sheep lung with the Ki values of 0.52nM, 0.18nM and 4nM, respectively. In addition, Montelukast Sodium has also shown the inhibitory effect with the IC50 of 10mM for leukotriene C3 in U937 cell membranes and 40mM for leukotriene B4 in THP-1 cell membranes. Apart from these, after oral treatment of Montelukast Sodium, it has been revealed to suppress leukotriene D4 receptor induced bronchoconstriction in conscious squirrel monkeys with ED50 value of 0.03±0.001mg/kg [1].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
