Drug Deliv Transl Res:包含壳聚糖基纳米颗粒负载热敏原位凝胶的马来酸氯苯那敏在过敏性鼻炎治疗中的研究

2019-05-16 AlexYang MedSci原创

最近,有研究人员制造了一个包含马来酸氯苯那敏(CPM)纳米颗粒的热敏凝胶,进行鼻腔给药从而对过敏性鼻炎进行有效的治疗。研究人员利用沉淀法获得了壳聚糖基纳米颗粒,之后在基于波洛沙姆407和卡波934p的黏附性热可逆凝胶中加入研制的NPs。研制的配方用来评估颗粒的大小、PDI、包封百分比和累积药物渗透百分比。研究发现,NP3配方具有最优的最小颗粒(143.9nm)、最大的包封比例(80.10±0.41

最近,有研究人员制造了一个包含马来酸氯苯那敏(CPM)纳米颗粒的热敏凝胶,进行鼻腔给药从而对过敏性鼻炎进行有效的治疗。

研究人员利用沉淀法获得了壳聚糖基纳米颗粒,之后在基于波洛沙姆407和卡波934p的黏附性热可逆凝胶中加入研制的NPs。研制的配方用来评估颗粒的大小、PDI、包封百分比和累积药物渗透百分比。研究发现,NP3配方具有最优的最小颗粒(143.9nm)、最大的包封比例(80.10±0.414%)和最高的药物渗透比例(90.92±0.531%)。优化的NP3配方之后由于热可逆原位凝胶的制作。他们的配方加强了鼻粘膜与药物的接触,增加和促进了药物的吸收,从而提供生物可利用性。G4配方被选择作为胶凝能力和粘接强度最优的配方。之后,研究人员利用组织学方法检查了优化后的G4配方带来的损伤。结果发现没有可见的组织损伤,表明了原位凝胶G4鼻传输纳米颗粒药物是安全的。

最后,研究人员指出,鼻内CPM NP装载原位凝胶是过敏性鼻炎的有效治疗方法。

哮喘和过敏性鼻炎(AR)是气道慢性炎症疾病并且相互影响着疾病的严重度。最近,有研究人员调查了是否生理盐水洗鼻(NSI)能够改善哮喘和过敏性鼻炎(AR)儿童的气道高反应性和临床参数。研究人员招募了20名AR和哮喘儿童,年龄在6-18岁。患者被随机分成了2组:洗鼻组(8名男孩和2名女孩)和对照组(8名男孩和2名女孩)。洗鼻组每天都进行NSI。所有的参与者接受了为期12周的孟鲁司特,左西替利嗪,吸入糖皮

Int Immunopharmacol:过敏性鼻炎中桔皮素能够促进T细胞分化

桔皮素具有广谱的抗炎症作用。最近,有研究人员评估了是否桔皮素在调控T调节细胞(Tregs)和减弱过敏性鼻炎(AR)中具有功能。研究发现,在AR组中,桔皮素和地塞米松(DXM)给药均能够减弱呼吸道炎症,减少血清OVA诱导的lgE的产生,但是只有桔皮素给药能够恢复细胞因子的平衡。在AR小鼠或者CD4+T细胞分化中,脾脏CD4+CD25+FOXP3+Treg细胞的丰度和FOXP3转录因子水平在桔皮素治疗

Clin Exp Otorhinolaryngol:虎耳草在过敏性鼻炎中的抗过敏作用研究

虎耳草提取物具有抗癌、抗过敏和抗氧化活性。最近,有研究人员调查了虎耳草提取物对过敏性鼻炎炎症中的作用。研究包括了4个不同的小组(组A:对照组;组B:过敏性鼻炎组;组C:300mg/kg处理组;组D:600mg/kg处理组),实验对象为BALB/c小鼠。研究发现,虎耳草提取物在组C和组D中对鼻症状、IL-13 mRNA的表达、鼻组织中嗜酸性细胞浸润/杯状细胞增生和OVA特异性lgE的产生均表现出了明

Int J Environ Res Public Health:亚洲糖尿病患者中二肽酰肽酶-4抑制剂与过敏性鼻炎相关性分析

最近,有研究人员尝试评估了二肽酰肽酶-4抑制剂(DPP-4)与过敏性鼻炎在糖尿病患者中可能的相关性。研究人员的研究群体包括了2009年到2012年之间的2型糖尿病(ICD-9-CM 250)患者群体,并分为DPP-4使用者和非使用者。研究人员在多变量逻辑回归分析模型中评估了倾向性评分来对过敏性鼻炎(ICD-9-CM 477.9)进行分析。每个组中包括了6204名患者。研究发现,DDP-4抑制剂使用

Clin Exp Allergy:肿瘤坏死因子α和白介素-5能够抑制嗅觉再生

嗅觉障碍在过敏性鼻炎患者中是一种常见的情况。这种情况被认为是由于炎症引起的嗅觉粘膜结构性和功能性的变化产生的。然而,目前对过敏性鼻炎嗅觉功能障碍的病理学理解仍旧不清楚。最近,有研究人员在过敏性鼻炎中调查了嗅觉神经细胞损伤的原因。研究发现,嗅球细胞(OSCs)表达了神经干细胞的标记。为了调查神经分化,研究人员通过免疫细胞组化染色发现Tuji1、GFAP、O4和OSCs量均显著增加。在对照和过敏性鼻炎
