    将N-月桂酰基谷氨酸钠(SLG)分别与十二烷基三甲基氯化铵(DTAC)和十二烷基甜菜碱(BS-12)以不同比例混合,研究不同类型表面活性剂之间的相互作用对表面化学性能和形成胶束的影响。通过规则溶液理论研究了不同摩尔比的复配体系的表面化学性质,使用激光光散射表征复配体系的胶束分布和平均流体力学半径,使用荧光探针法测量复配体系的微极性和胶束聚集数。结果表明,两个复配体系均表现出全面增效的协同作用,均在SLG摩尔分数x=50%时表现出最佳协同效应,并且阴离子表面活性剂与阳离子表面活性剂之间具有更强的作用力。SLG/DTAC复配体系在10倍cmc下趋向于产生单一稳定且小于单一组分的聚集体,SLG/BS-12复配体系在10倍cmc下形成棒状胶束,胶束大小分布较宽。

    The mixture of sodium N-lauroyl glutamate (SLG) and dodecyltrimethylammonium chloride (DTAC) and the mixture of SLG and dodecyl betaine (BS-12) in different ratios were studied to investigate the effects of the interactions between different types of surfactants on surface chemical properties and micelle formation. The surface chemical properties of the mixed systems with different molar ratios were investigated by regular solution theory. Laser light scattering was used to characterize the micelle distribution and average hydrodynamic radius of the mixed systems. Fluorescence probing method was used to measure micropolarity and micellar aggregation number. The results indicated that both the mixed systems showed synergy of overall enhancement. The two systems showed the best synergy when x (SLG) =50%, and the interaction between anionic and cationic surfactants was stronger. The SLG/DTAC system tended to produce single stable aggregates at a concentration of ten times cmc, but the size after mixing was smaller than that of single components. The SLG/BS-12 system formed rod-shaped micelles at a concentration of ten times cmc, and the micelle size distribution was wide.

    孙小乐,郭建英,谢炙轩,张雷,杨志超,刘生玉
    2020 (8):  523-528.  doi: 10.3969/j.issn.1001-1803.2020.08.003
    摘要 ( 226 )   HTML ( 8 )   PDF(1446KB) ( 274 )  

    低阶煤中有机质与矿物质润湿性的差异决定了浮选作业的效果,为提高低阶煤的浮选效率,采用先后吸附钙离子与表面活性剂(C12EO15),再用超声波脱附C12EO15的方法处理低阶煤泥。结果表明,钙离子会促进C12EO15吸附在有机质表面,吸附量由7.14 mg/g提升至7.39 mg/g。当脱附处理60 s后,C12EO15会从有机质表面脱附下来,但会进一步吸附在矿物质表面。脱附处理后有机质表面疏水官能团与亲水官能团的含量同时增加,润湿热值由31.79 J/g提升至32.93 J/g。随脱附时间的增加,浮选精煤的产率与精煤灰分也随之上升,脱附处理30 s时,可以得到较优浮选效果,精煤产率为72.01%,精煤灰分为30.85%。

    The quality of flotation depends on the different wettability between organic and mineral matter. A method was adopted in order to promote the performance of low-rank coal flotation, in which the low-rank coal slime first adsorbed calcium ions and then surfactant molecules (C12EO15) and reached adsorption equilibrium, and was finally treated by ultrasonic wave to desorb the surfactant. The results indicated that calcium ions could promote the adsorption of C12EO15 on the surface of organic matter, in which the adsorption capacity was increased from 7.14 mg/g to 7.39 mg/g. When the time of desorption treatment reached 60 s, C12EO15 molecules would desorb from the surface of organic matter but further adsorb on the surface of mineral matter. The amounts of hydrophilic and hydrophobic functional groups on the surface of organic matter both increased after desorption treatment, and the wetting heat was improved from 31.79 J/g to 32.93 J/g. As the time of desorption treatment increased, the yield and ash content of clean coal increased, respectively. When the time of desorption treatment was 30 s, the best flotation performance could be obtained, in which the yield of clean coal was 72.01% and the ash content of clean coal was 30.85%.

    以卵磷脂、胆固醇、表面活性剂为壁材制备传质体,通过薄膜水合法分别将苯乙基间苯二酚(PR)与白藜芦醇/羟丙基-β-环糊精(RSV/HP-β-CD)复合物包封在传质体的磷脂双分子层和水性隔室中,获得环糊精复合物传质体(DCTs)。研究了膜软化剂及其添加量、添加方式对DCTs粒径、PDI、Zeta电位、包封率的影响。结果表明,使用0.012 mol/L的T20制得的DCTs粒径较小,为112.43 nm,PDI为0.16,Zeta电位为-34.90 mV,PR与RSV包封率最高,分别为77.07%和60.67%。通过对DCTs体外释放、透皮、细胞毒性及B16-F10细胞内黑色素含量研究,发现DCTs实现了活性物缓释并防止活性物降解,减小了组合活性物透皮递送的渗透性差异,降低了游离活性物的细胞毒性,增强了组合活性物的协同效果,从而减少了B16-F10细胞的黑素生成。

    Active-in-cyclodextrin-in-transfersomes (DCTs), which encapsulated phenylethyl resorcinol (PR) and resveratrol/hydroxypropyl-β-cyclodextrin (RSV/HP-β-CD) inclusion complexes in the phospholipid bilayer and aqueous compartments of the transfersomes, were prepared by thin film hydration using lecithin, cholesterol, and surfactant as encapsulation materials. The effects of edge activator, their concentrations and addition methods on the particle size, PDI, Zeta potential and encapsulation efficiency of DCTs were studied. Results show that the particle size of DCTs prepared by 0.012 mol/L Tween 20 is 112.43 nm, PDI is 0.16, Zeta potential is -34.90 mV, and the high entrapment efficiency of PR and RSV are achieved as 77.07% and 60.67%, respectively. Through in vitro release, transdermal, cytotoxicity and melanin content in B16-F10 cells of DCTs, it was found that DCTs achieved drug sustained release and prevented drug degradation, reduced the permeability difference of transdermal delivery of combination drugs, decreased the cytotoxicity of free drugs, enhanced the synergistic effect of the combination drug, and reduced the melanin content of B16-F10 cells.

    摘要 ( 518 )   HTML ( 13 )   PDF(1122KB) ( 482 )  

    通过体外细胞实验和脱发小鼠模型,研究了薰衣草精油与亚洲薄荷精油对毛发生长的促进作用。通过细胞实验考察两种精油对人永生角质形成细胞血管内皮生长因子(VEGF)和角质形成细胞生长因子(KGF)分泌的影响;通过小鼠模型考察两种精油对新生毛发生长长度、脱毛区皮肤组织学变化、毛囊数目、真皮厚度、皮肤VEGF和KGF表达的影响。结果表明,两种精油均能促进毛发伸长,增加脱毛区皮肤毛囊数目和真皮层厚度,延长毛发处于生长期的时间,但二者的作用机制不同;薰衣草精油促进KGF的分泌,亚洲薄荷精油则促进VEGF的分泌,动物实验结果与细胞实验结果相符。说明薰衣草精油和亚洲薄荷精油均有促毛发生长的功效。

    The effects of lavender (Lavandula angustifolia) essential oil and Asian mint (Mentha asiatica) essential oil on hair growth were studied by cell experiment in vitro and hair loss mouse model. The effects of two essential oils on the secretion of vascular endothelial growth factor (VEGF) and keratinocyte growth factor (KGF) of human immortalized keratinocytes were detected by cell experiment. The effects of two essential oils on hair regrowth length, histological changes of skin in depilated area, number of hair follicles, thickness of dermis, and expressions of skin VEGF and KGF were studied by mouse model. The results show that both lavender essential oil and Asian mint essential oil can promote hair elongation, increase the number of hair follicles and dermal thickness in the depilated area, and prolong the anagen hair cycle in mice. However, their mechanisms might be different. Lavender essential oil promotes the secretion of KGF, while Asian mint essential oil increases the secretion of VEGF. The results of animal experiments are consistent with those of cell experiments. It demonstrates that both lavender essential oil and Asian mint essential oil have hair-promoting effects.

    摘要 ( 333 )   HTML ( 12 )   PDF(1290KB) ( 531 )  

    研究了不同程度月桂酸表面改性氧化锌纳米颗粒的Pickering乳化性能。通过调节月桂酸用量来改变氧化锌纳米颗粒表面亲疏水性(接触角θ),并探讨了不同接触角氧化锌纳米颗粒稳定的Pickering乳液的乳滴粒径、相转变及稳定性变化规律。结果表明,部分亲水的氧化锌纳米颗粒稳定(三相接触角40°~60°)的O/W型乳液具有最小的液滴尺寸和最优的稳定性。在最优条件下利用Pickering乳液聚合法制备了表面负载氧化锌纳米颗粒的有机硅弹性微球,粒径为5~20 μm。

    The Pickering emulsifying properties of lauric acid-modified zinc oxide nanoparticles were studied. By adjusting the amount of lauric acid, the wettability (contact angle θ) of ZnO nanoparticles were changed, and the droplet size, phase transition and stability of the Pickering emulsions stabilized by ZnO nanoparticles with different contact angles were discussed. The results indicated that by using ZnO nanoparticles that were partially hydrophilic (three-phase contact angle of 40°-60°), the O/W Pickering emulsion thus prepared exhibited the smallest droplet size and optimal stability. Furthermore, silicone elastic microspheres with ZnO nanoparticles on the surface were prepared under the optimal conditions by Pickering emulsion polymerization, and the particle size of silicone elastic microspheres was 5-20 μm.

    使用乳化法提高了鞣花酸的分散性,并研究了鞣花酸水溶液和乳液在不同处理温度、紫外光照射及部分介质溶液中的稳定性。结果表明,鞣花酸水溶液在存放过程中稳定性逐渐下降,高的处理温度、紫外光照射及无机盐NaCl、羧基纤维素纳等添加剂均不利于鞣花酸水溶液的稳定性,甘油、β-环糊精等添加剂则有利于提高鞣花酸水溶液的稳定性,鞣花酸经过乳化后可提高鞣花酸在存放过程中的稳定性。

    The dispersibility of ellagic acid was improved by emulsification, and the stability of ellagic acid aqueous solution and emulsion in different treatment temperatures, ultraviolet irradiation and partial medium solutions was studied. The results show that the stability of the ellagic acid aqueous solution gradually decreased during storage. High treatment temperature, UV irradiation, inorganic salt NaCl, carboxyl cellulose sodium and other additives are not conducive to the stability of ellagic acid aqueous solution, while glycerin, β-cyclodextrin and other additives are beneficial to the stability of ellagic acid aqueous solution. The emulsification of ellagic acid can improve the stability of ellagic acid during storage.

    摘要 ( 440 )   HTML ( 11 )   PDF(1228KB) ( 360 )  

    研究了柚皮苷对紫外线诱导昆明小鼠皮肤屏障损伤的保护作用。将25只SPF级昆明小鼠随机分为5组:空白对照组,模型组(UV照射组),阳性对照组(28.39 mmol/L维生素C),低、高剂量柚皮苷涂抹组(0.35和3.5 mmol/L柚皮苷)。除空白对照组,其他4组小鼠模拟日光紫外线(UVA + UVB)照射,建立小鼠光损伤皮肤模型,每次UV照射前,提前2 h分别涂抹相同剂量(100 μL/只)的药物。通过测试小鼠皮肤经表皮失水(TEWL)、H&E染色、胶原纤维染色(Masson染色),以及小鼠皮肤组织中的超氧化物歧化酶(SOD)、过氧化氢酶(CAT)的活力,丙二醛(MDA)的含量,活性氧(ROS)清除能力来探究柚皮苷对皮肤光损伤的作用途径;免疫组化染色(IHC染色)检测丝聚合蛋白(FLG)、内披蛋白(IVL)、水通道蛋白3 (AQP3)以评价柚皮苷对紫外线损伤皮肤的屏障相关功能。与模型组相比,柚皮苷涂抹组小鼠皮肤抑制皮肤表皮厚度增加,给药组胶原量增加;低、高剂量柚皮苷涂抹组可以显著减少光损伤小鼠皮肤中水分的流失(p<0.05);柚皮苷显著提高小鼠皮肤组织中SOD、CAT的活力(p<0.05),显著降低MDA的含量(p<0.05)及清除ROS的含量;IHC染色研究表明柚皮苷涂抹组皮肤中FLG、IVL、AQP3蛋白表达量增加(p<0.05)。

    The protective effect of naringin on UV-induced skin barrier damage in KM mice was studied. Twenty-five SPF KM mice were randomly divided into 5 groups: blank control group, UV model group (UV irradiation group), positive control group (28.39 mmol/L vitamin C), low and high-dose naringin smear groups (0.35, 3.5 mmol/L naringin). Except for the blank control group, the other four groups of mice were simulated with sunlight ultraviolet (UVA+UVB) radiation to establish a mouse photo-damaged skin model. Before each UV irradiation, the same amount (100 μL/mouse) of naringin with the indicated dose was applied 2 h in advance. The effects of naringin on skin photodamage were investigated by testing the skin TEWL, H&E staining, Masson staining, the activities of superoxide dismutase (SOD) and catalase (CAT), malondialdehyde (MDA) content, and the scavenging ability of reactive oxygen species (ROS) in mice skin tissues. Moreover, immunohistochemical staining (IHC staining) of filaggrin (FLG), involucrin (IVL) and aquaporin 3 (AQP3) was used to evaluate the skin barrier-related functions of naringin against UV-damaged skin. Compared with the model group, the skin of the naringin administration group inhibited the increase in skin epidermal thickness, and the amount of collagen in the administration group increased; the low and high-dose naringin smear group could significantly reduce the loss of water in the skin of mice with UV damage (p<0.05). Naringin significantly increased the activity of SOD and CAT (p<0.05), significantly reduced the content of MDA (p<0.05), and eliminated the content of ROS in the skin of mice. IHC staining study showed that the protein expression level of FLG, IVL and AQP3 increased in the naringin-administered group (p<0.05).
