Histamine H1 receptor[1]

[体外研究]

在研究组中,蛇床子素(p <0.0001)和非索非那定(p <0.001)抑制由组胺诱导的HRH-1 mRNA表达增加。在用组胺/ Osthole培养的细胞中也观察到该结果;其中组合物质与组胺相比降低HRH-1 mRNA表达(p <0.0001)[1]。当Osthole以高达100μM的剂量使用时,细胞活力的评估未检测到明显的毒性。然而,当剂量达到500μM时,Osthole开始显示出毒性作用。基于这些观察结果,Osthole用于所有体外研究,剂量范围为10至100μM。蛇床子素剂量依赖性地促进成骨细胞分化,如成骨细胞分化标志物基因如I型胶原(col1),骨涎蛋白(BSP)和骨钙蛋白(OC)的上调所示(培养2天)。 Osthole以剂量依赖的方式促进小鼠原代成骨细胞的ALP活性[2]。

[体内研究]

每天以5mg/kg的剂量向小鼠颅盖骨皮下注射Osthole可显着刺激局部骨形成,如最后一次注射后2周收获的颅骨样品的组织学分析所示,并用H＆E橙色G染色。组织形态学分析显示Osthole与阳性对照微管抑制剂TN-16一样,对骨形成有显着影响。然而,当Osthole以每天1mg/kg的剂量使用时,没有观察到这种效果。腹腔注射Osthole 8周显着逆转卵巢切除大鼠的骨质流失。用三硝基苯酚一品红染色的L4样品的组织学检查显示用Osthole处理的切除卵巢的大鼠中的小梁结构的部分恢复。组织形态学分析显示,使用Osthole治疗可显着增加总BMD,骨小梁体积和小梁厚度,并减少小梁分离[2]。

[细胞实验]

在第一个研究日的上午7点到9点之间从参与者收集外周血样品，并将这些样品浓缩在具有K3EDTA的分组管中。然后制备新鲜的PBMC。将分离的细胞以RPX-1640每孔1×106接种在24孔板上，并补充1％热灭活的人AB血清，1％庆大霉素和0.25％PHA。 24小时后向每个孔中加入活性试剂，纯培养基形成每种物质的对照。然后在另外三天后收获细胞[1]。

[动物实验]

小鼠[2]将4周龄ICR瑞士小鼠皮下注射到颅骨表面，每天两次或不同时处理Osthole，连续5天，剂量为1和5 mg / kg /天（每组3只小鼠））。微管抑制剂TN-16用作阳性对照（每天5mg / kg，通过皮下注射，每天两次，持续2天;每组3只小鼠）。处理后3周对所有小鼠实施安乐死，解剖颅盖骨，用10％磷酸盐缓冲的福尔马林固定2天，在10％EDTA中脱钙2周，并包埋在石蜡中。切割组织切片并用苏木精和伊红橙G染色。使用OsteoMeasure系统通过组织形态学定量颅骨表面上的新骨区域。为了测量矿物质附着率（MAR）和骨形成率（BFR），在第7天和第14天通过腹膜内注射（20mg / kg）进行双钙黄绿素标记，并且在第二次标记后7天对小鼠实施安乐死。标签在塑料部分进行检查。将解剖的颅骨样品固定在75％乙醇中并包埋在甲基丙烯酸甲酯中。用荧光显微镜检查未染色的横切面（3μm厚）。 MAR和BFR使用OsteoMeasure系统测量。大鼠[2]使用30只6个月大的雌性Sprague-Dawley大鼠。在腹膜内戊巴比妥注射（30mg / kg）麻醉后，将大鼠按体重随机分成三组进行手术（n = 10 /组）：组1：假手术，然后进行PBS载体治疗（假+ VEH）;第2组：卵巢切除术后接受载体治疗（OVX + VEH）;第3组：卵巢切除术，然后进行Osthole治疗（OVX + OST）。手术后1个月开始治疗，持续8周。每天一次口服给予载体或Osthole（100mg / kg /天），持续8周。在实验结束时对大鼠实施安乐死之前，使用双能X射线吸收测定法测量总骨矿物质密度（BMD，g / m 2）。然后解剖第四腰椎（L4）用于组织形态学和微计算机断层扫描（μCT）分析，并且左股骨轴用于生物力学测试。
