Background : The aim of this study was to develop a stable skin emulsifier from mupirocin. Materials and methods : This study was performed in the Department of Pharmacy, Tehran University of Pharmaceutical Sciences from November 2016 to September 2015. Initially, preformulation studies were performed on mupirocin powder and a standard diagram was drawn. Next, the bases of the drug-free emulsifiers were made, their stability was investigated and the superior formulation was selected. The next step was the formulation of the emulsion containing the drug. Further studies such as determining the amount of active ingredient, releasing the drug in vitro and determining the aura of stunting were performed. Results : Emulsifier containing 940 carbomer, 5% liquid paraffin, 0.4% tween 20 and 1.1% spin 20 were selected as the top formulation. The results of stability, dispersibility and other tests were appropriate. The amount of active ingredient in the formulations was between 90 and 110%. Within 8 hours, the drug was released at approximately 85%. Rheologically, the formulation followed non-Newtonian behavior. It also showed the behavior of plastics and thixotropes. Observing the growth inhibition zone around drug-containing formulations indicateed that mupirocin was released from the emulsion base and prevented the growth of Staphylococcus aureus bacteria. Conclusion : A stable emulsion formulation can be prepared from mupirocin. It is suggested that accelerated stability studies and periodic and scale-up formulations be carried out for industrial production.
背景:以莫匹罗星为原料制备稳定的皮肤乳化剂。材料与方法:本研究于2016年11月- 2015年9月在德黑兰药科大学药学系进行。首先对莫匹罗星粉末进行了处方前研究,并绘制了标准图。其次,制备了无药乳化剂的碱,考察了其稳定性,选择了最佳配方。下一步是配制含有该药物的乳剂。进一步的研究,如确定有效成分的量,体外释放药物和确定发育迟缓的先兆。结果:选择含940卡波姆、5%液体石蜡、0.4%吐温20、1.1%自旋20的乳化剂为最佳配方。稳定性、分散性等试验结果较好。制剂中有效成分含量在90% ~ 110%之间。8小时内,药物以85%的速率释放。流变学上,这个公式遵循非牛顿的行为。它还显示了塑料和触变物的行为。观察含药制剂周围的生长抑制带,发现莫匹罗星从乳剂基质中释放出来,抑制了金黄色葡萄球菌的生长。结论:用莫匹罗星可制得稳定的乳状制剂。建议为工业生产进行加速稳定性研究和定期和规模化配方。

Background : Prenatal intoxication with trimethyletin (TMT) induces widespread neuronal death in the central nervous system by inducing oxidative stress. The aim of this study was to evaluate the antioxidant effect of gallic acid (GA) on the neuronal density of the entorhinal cortex, hippocampal pyramidal cells and oxidative stress parameters in the fetal forebrain following TMT intoxication. Materials and methods : 25 pregnant Wistar female rats were randomly divided into 5 groups, including control, TMT+Saline, TMT+GA100, TMT+GA200 and TMT+GA400. To induce TMT intoxication, TMT (9 mg/kg body weight) was injected intraperitoneally into pregnant rats on embryonic day (ED) 14. From the ED12 to ED18, the treatment groups received orally GA at different doses. After fetal cesarean section on the ED21, neuronal density assessment of the entorhinal cortex, CA1 and CA3 regions of the hippocampus and forebrain level of catalase (CAT), superoxide dismutase (SOD) and malondialdehyde (MDA) was performed by ELISA. Results : The results showed a significant increase in the activity of CAT and SOD enzymes and a significant decrease in MDA in the forebrain of GA-receiving groups compared to the TMT + Saline group. In addition, increased neuronal density was observed in the entorhinal cortex and CA1/CA3 regions of the hippocampus in the GA treated rats compared to the TMT + Saline group. Conclusion : Prenatal TMT intoxication induced oxidative stress in the fetal forebrain, causing damage to the entorhinal cortex and hippocampus of rat fetal brain. On the other hand, GA prevented and improved neuronal damage in these areas of the fetal brain.
背景:产前三甲基letin (TMT)中毒通过诱导氧化应激在中枢神经系统中引起广泛的神经元死亡。本研究旨在探讨没食子酸(GA)对TMT中毒后胎儿前脑内嗅皮质神经元密度、海马锥体细胞及氧化应激参数的抗氧化作用。材料与方法:25只Wistar妊娠雌性大鼠随机分为5组,分别为对照组、TMT+生理盐水组、TMT+GA100组、TMT+GA200组和TMT+GA400组。为了诱导TMT中毒,在胚胎第14天(ED)腹腔注射TMT (9 mg/kg体重)。从ED12到ED18,治疗组口服不同剂量的GA。剖宫产后胎儿ED21,采用酶联免疫吸附法(ELISA)检测胎儿内嗅皮质、海马CA1、CA3区神经元密度及前脑过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、丙二醛(MDA)水平。结果:与TMT +生理盐水组相比,ga给药组大鼠前脑CAT、SOD酶活性显著升高,MDA含量显著降低。此外,与TMT +生理盐水组相比,GA处理大鼠的内嗅皮质和海马CA1/CA3区神经元密度增加。结论:产前TMT中毒诱导胎儿前脑氧化应激,造成大鼠胎儿脑内嗅皮质和海马损伤。另一方面,GA预防和改善了胎儿大脑这些区域的神经元损伤。

On the other hand, GA prevented and improved neuronal damage in these areas of the fetal brain.","PeriodicalId":18492,"journal":{"name":"MEDICAL SCIENCES JOURNAL","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91369113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background : Interferon (IFN) are small proteins that belong to the cytokine family and may interfere with viral infections and some cancers. There are many studies focused on the PEGylated interferon’s bioactivity. In this study, we used solid lipid nanoparticles (SLNs) to produce new drug formulations, with the aim of reducing costs, increasing effectiveness, and also reducing side effects, and the biological effects of the formulation and comparing the obtained results with the interferon alpha-2b and PEGylated interferon alpha-2b. Materials and methods : In this study, we evaluateed the toxicity and bioactivity of three formulations: interferon alpha-2b, PEGylated interferon alpha-2b, and encapsulated interferon alpha-2b with solid lipid nanoparticles using the MTT method and cytopathic inhibition assay (CPE), respectively. Results : The toxic effects of interferon encapsulated solid lipid nanoparticle (SLN-INF) was comparable with interferon and PEGylated interferon. In addition, empty solid lipid nanoparticles had no toxic effects on cells. The SLN-IFN showed higher bioactivity than the other samples tested (interferon alpha-2b, PEGylated interferon alpha-2b) and maintained its bioactivity over time. Conclusion : The results of this study indicate that interferon alpha-2b conjugated with solid lipid nanoparticles is a capable formulation with sufficient bioactivity and acceptable toxicity as compared to PEGylated interferon and can be applied in clinical trials in future studies.
背景:干扰素(IFN)是细胞因子家族的小蛋白,可能干扰病毒感染和某些癌症。聚乙二醇化干扰素的生物活性是目前研究的热点。在本研究中,我们使用固体脂质纳米颗粒(SLNs)生产新的药物配方,目的是降低成本,提高疗效,减少副作用,以及配方的生物学效应,并将所获得的结果与干扰素α -2b和聚乙二醇化干扰素α -2b进行比较。材料和方法:在本研究中,我们分别采用MTT法和细胞病变抑制试验(CPE)评估了干扰素α -2b、聚乙二醇化干扰素α -2b和固体脂质纳米颗粒包封干扰素α -2b三种制剂的毒性和生物活性。结果:干扰素包封固体脂质纳米颗粒(SLN-INF)的毒性作用与干扰素和聚乙二醇化干扰素相当。此外,空固体脂质纳米颗粒对细胞无毒性作用。SLN-IFN的生物活性高于其他测试样品(干扰素α -2b,聚乙二醇化干扰素α -2b),并随时间保持其生物活性。结论:本研究结果表明,与聚乙二醇化干扰素相比,α -2b结合固体脂质纳米颗粒的干扰素具有足够的生物活性和可接受的毒性,可以在未来的研究中用于临床试验。
