Description
技术领域
本发明涉及化妆品技术领域,具体是指一种含有纳米包埋卵黄抗体的多效修护面膜液及其制备方法。
背景技术
痤疮是一种常发于青少年的慢性炎症性皮肤病,临床表现一般常见病况为粉刺、丘疹、炎症等皮损,发病病程长且不定,容易在面部遗留凹陷和增生瘢痕,因此对于青少年生活酬酢及心理影响很大。
痤疮丙酸杆菌常驻在皮肤表面,和其他皮肤常驻菌一样,正常情况下对人体没有危害,这些皮肤常驻菌一同构成了皮肤的稳态环境。治疗痤疮通常是复杂的,可能涉及使用局部抗生素,激素等。当皮肤毛孔被过剩的油脂和死皮细胞阻碍时,就会产生一种厌氧环境,痤疮丙酸杆菌(Propionibacterium acnes,Pacnes)可以加速生长。目前预防和治疗方法有限,缺乏安全可靠的疫苗诱导针对寻常痤疮的保护性免疫,市面上治疗痤疮基本是采用激素类药物,抗生素的使用破坏了正常菌群,容易引起菌群失调和耐药,对人体健康不利。
发明内容
为了克服现有技术存在的不足,本发明提供一种含有纳米包埋卵黄抗体的多效修护面膜液及其制备方法,本发明的上述目的是通过以下技术方案实现的:
本发明的目的在于提供一种安全有效,吸收效果明显,在修复滋养肌肤的同时,修护由肌肤过敏、细菌感染、皮脂腺角化异常、炎症等原因引起的痤疮的纳米修护面膜液。由于痤疮会上调基质金属蛋白酶MMP-1的表达水平,从而降低皮肤真皮层的厚度,造成皮肤萎缩性瘢痕,即“痘坑”。而明胶的前体正是胶原蛋白,其降解后能促进皮肤伤口愈合、滋润皮肤,使皮肤得以修复。因此本发明选用明胶作为纳米粒的载体,采用溶剂挥发法制备出卵黄抗体纳米粒。
含有纳米包埋卵黄抗体的多效修护面膜液,首先进行痤疮病原菌的培养,制备细菌抗原、卵黄抗体,然后提取卵黄抗体,制备纳米明胶颗粒,采用纳米明胶颗粒包裹卵黄抗体制成纳米卵黄抗体原液,最后添加保湿剂、流动调节剂、活性成分和增湿剂,制成面膜液。
进一步的,所述的保湿剂为1,3-丁二醇、1,2-戊二醇、甘油;所述的流动调节剂为羟乙基纤维素、卡波姆、黄原胶;所述的活性成分为海藻糖、尿囊素、丝氨酸、谷氨酸;所述的增稠剂为PEG。
含有纳米包埋卵黄抗体的多效修护面膜液的制备方法,包括如下步骤:
步骤S1:痤疮病原菌的培养;
步骤S2:三种细菌的蛋白质抗原和菌体抗原制备;
步骤S3:卵黄抗体制备;
步骤S4:卵黄抗体提取;
步骤S5:纳米明胶颗粒制备;
步骤S6:纳米明胶颗粒包裹卵黄抗体;
步骤S7:制备面膜原液。
进一步的,步骤S1包括:
(1)葡萄球菌的培养
利用LB培养基培养金黄色葡萄球菌和表皮葡萄球菌,将LB培养基置于高压灭菌锅灭菌,待其冷却后在超净台中无菌接种,并放入恒温箱培养;
(2)痤疮丙酸杆菌的培养
将LB培养基调节pH6.8-7.0,随后与液体石蜡分别高温高压灭菌,待其冷却后在超净台中无菌接种痤疮丙酸杆菌,隔绝氧气迅速用橡胶塞塞紧瓶口,最后将接种后的LB培养基放在台式恒温振荡器中37℃培养。
进一步的,步骤S2包括:
利用甲醛法和煮法分别灭活这三种菌体,分别得到金黄色葡萄球菌蛋白质抗原、金黄色葡萄球菌菌体抗原、表皮葡萄球菌蛋白质抗原、表皮葡萄球菌菌体抗原、痤疮丙酸杆菌蛋白质抗原、痤疮丙酸杆菌菌体抗原。
进一步的,步骤S3包括:
从鸡场购入产蛋母鸡,不注射抗原饲养一周,确保产蛋母鸡能正常下蛋后,在鸡的颈部和翅膀皮下多点分别注射80μg步骤S2的细菌抗原,在初次免疫两周后进行第二次免疫,之后每间隔一周免疫一次,加强免疫三次。
进一步的,步骤S4包括:
采用水稀释-硫酸铵法:取免疫后的蛋黄,用超纯水稀释卵黄,卵黄和水体积比为1:8,混匀等待分层,取上清液加入等体积的饱和硫酸铵,调节pH为5.0;随后,离心后弃上清,用PBS溶解悬浮沉淀,将抗体装入透析袋中,将透析袋放入透析液里,4℃环境下持续搅拌除盐,每2h更换一次透析液,一共透析24h,制备Part D纳米卵黄抗体原液。
进一步的,步骤S5包括:
称取0.416-0.832g明胶于100mL烧杯中,加入8.3mL双蒸水,于50℃,400rpm搅拌溶解,边搅拌边加入8.3-16.6mL丙酮,室温静置20min,弃去上清液,加入10mL双蒸水,50℃,200rpm彻底溶解底部沉淀,加入1mol/L的HCl调节pH至2.5;滴加丙酮30-60mL,再加入以戊二醛和丙酮体积比为1:1000配置的溶液2-4mL,室温1000rpm持续搅拌5h,挥发丙酮及戊二醛,用双蒸水稀释10倍,使用40KD透析袋,在双蒸水中透析24h后,在-4℃静置保存。
进一步的,步骤S6包括:
调节明胶纳米颗粒溶液pH 7.0,向浓度为1mg/mL的纳米颗粒中加入终浓度为45μg/mL卵黄抗体,室温震荡2h后,进行包封率鉴定,检测释放速率。
进一步的,步骤S7包括:
(1)制备Part A:称取体积百分数为6%的1,3-丁二醇、4%的1,2-戊二醇、8%的甘油、2%的泛醇和质量百分数为0.2%的羟乙基纤维素、0.1%的卡波姆、0.2%的黄原胶、0.2%的尿囊素、1%的海藻糖、0.1%的EDTA二钠、0.5%的丝氨酸于烧杯中,混匀备用;
(2)将Part A搅拌,分散均匀至无不溶物,加热至80-85℃,转速为500rpm,保温20min,开始降温;
(3)降温至45℃,加入Part B原料:质量百分数为2%的甜菜碱和0.25%的谷氨酸,搅拌至无不溶物;
(4)加入Part C:质量百分数为0.5%的PEG,至A和B混合液中,搅拌至均匀透明,置于室温条件下,待其正常散热降温;
(5)将Part A、PartB和Part C混合,加入已制备的Part D:纳米卵黄抗体原液,搅拌均匀,三者混合液与Part D的体积比为10:1;
(6)使用300目滤布过滤出料;
(7)基础面膜稳定性测定。
本发明与现有技术相比的有益效果是:
(1)卵黄抗体易制备、成本低廉,适合量产,是良好的抗生素替代品,抗生素已对我们日常生活产生重大的危害,许多微生物都对其产生了强耐药性,若任其滥用,后果不堪设想,使用卵黄抗体可以避免使用抗生素带来的耐药危害,抗菌效果优良,在不久的未来以卵黄抗体为代表的抗生素替代品将会成为治疗疾病的主流。
(2)通过对提取出的抗体进行蛋白质纯度的检测发现水稀释-硫酸铵法提取出的IgY,条带清晰,无拖尾现象,杂蛋白少,卵黄抗体纯度高,证明水稀释-硫酸铵法优于水稀释-氯化钠法,更优于盐析法、有机溶剂沉淀法、等电点沉淀法、重金属离子沉淀法等现有技术。
(3)通过设计出抗痤疮卵黄抗体纳米制剂,卵黄抗体治疗痤疮比起传统方法有更快速的效果,其高疗效、副作用小的特点使其具有广阔的市场,具有广阔的发展前景。
(4)添加纳米颗粒,给药量少,对皮肤刺激减少,便于透皮吸收和缓释的作用。成本价格低廉,原材料易制取,适用于大量制取。
(5)将纳米卵黄制剂与面膜精华液混合,有易于其与肌肤细胞结合,有助于改善面部肌肤环境,同时也可以打开毛孔,便于药物吸收。在此同时也抑制了痤疮杆菌的生长,从根源上解决了痤疮发源,有效治疗痤疮症状。

具体实施方式
下面通过具体实施例详述本发明,但不限制本发明的保护范围。如无特殊说明,本发明所采用的实验方法均为常规方法,所用实验器材、材料、试剂等均可从商业途径获得。
实施例1
使用特异性抗体作为抗菌药物是一种生物防治方法,这种免疫疗法可替代传统的抗生素治疗。卵黄抗体来源广泛,效果确实,安全可靠,使用方便。
现如今,面膜已成为当代年轻人青睐的日常皮肤保养用品,面膜液的成分便是对面部皮肤进行修复、疗养以及改善的关键。因此,针对痤疮,我们可以改变面膜液的常规成分,添加特异性卵黄抗体,达到皮肤清洁与修复的目的。
IgY作为替代抗生素的新型添加剂正在引起人们的关注,IgY取代抗生素,不会产生药物残留,是一种安全的绿色添加剂。
卵黄抗体作用具有特异性,例如针对痤疮丙酸杆菌的卵黄抗体纳米制剂只针对这种病原菌,不会破坏皮肤微生物稳态。另一方面由于其纳米制剂的特性,给药量少,对皮肤刺激减少。抗痤疮卵黄抗体纳米制剂,可以避免使用抗生素带来的耐药危害,其小剂量高疗效的特点还可以减少给药,减少副作用。由于纳米制剂便于透皮吸收的特点,能更加快速到达有菌的部位,发挥卵黄抗体的抗菌效果,真正起到见效快、效果好的作用,填补市场空白。卵黄抗体无残留、剂量小,符合绿色理念,更容易被青年人接受。我国畜牧业发达,蛋鸡来源丰富,制取卵黄抗体也变得方便且低成本。抗痤疮卵黄抗体纳米制剂其相比较于市面上的现有药物有着更广阔的发展空间,具有强大的市场。
本发明的目的在于提供一种安全有效,吸收效果明显,在修复滋养肌肤的同时,修护由肌肤过敏、细菌感染、皮脂腺角化异常、炎症等原因引起的痤疮的纳米修护面膜液。由于痤疮会上调基质金属蛋白酶MMP-1的表达水平,从而降低皮肤真皮层的厚度,造成皮肤萎缩性瘢痕,即“痘坑”。而明胶的前体正是胶原蛋白,其降解后能促进皮肤伤口愈合、滋润皮肤,使皮肤得以修复。因此本设计选用明胶作为纳米粒的载体,采用溶剂挥发法制备出卵黄抗体纳米粒。
步骤S1:痤疮病原菌的培养
(1)葡萄球菌的培养
利用LB培养基培养金黄色葡萄球菌和表皮葡萄球菌,将LB培养基置于高压灭菌锅灭菌,待其冷却后在超净台中无菌接种,并放入恒温箱培养;
(2)痤疮丙酸杆菌的培养
将LB培养基调节pH6.8-7.0,随后与液体石蜡分别高温高压灭菌,待其冷却后在超净台中无菌接种痤疮丙酸杆菌,隔绝氧气迅速用橡胶塞塞紧瓶口,最后将接种后的LB培养基放在台式恒温振荡器中37℃培养。
步骤S2:三种细菌的蛋白质抗原和菌体抗原制备
利用甲醛法和煮法分别灭活这三种菌体,分别得到金黄色葡萄球菌蛋白质抗原、金黄色葡萄球菌菌体抗原、表皮葡萄球菌蛋白质抗原、表皮葡萄球菌菌体抗原、痤疮丙酸杆菌蛋白质抗原、痤疮丙酸杆菌菌体抗原。
步骤S3:卵黄抗体制备
从鸡场购入产蛋母鸡,不注射抗原饲养一周,确保产蛋母鸡能正常下蛋后,在鸡的颈部和翅膀皮下多点分别注射80μg步骤S2的细菌抗原,在初次免疫两周后进行第二次免疫,之后每间隔一周免疫一次,加强免疫三次。
步骤S4:卵黄抗体提取
采用水稀释-硫酸铵法:取免疫后的蛋黄,用超纯水稀释卵黄,卵黄和水体积比为1:8,混匀等待分层,取上清液加入等体积的饱和硫酸铵,调节pH为5.0;随后,离心后弃上清,用PBS溶解悬浮沉淀,将抗体装入透析袋中,将透析袋放入透析液里,4℃环境下持续搅拌除盐,每2h更换一次透析液,一共透析24h,制备Part D纳米卵黄抗体原液。
步骤S5:纳米明胶颗粒制备
称取0.416-0.832g明胶于100mL烧杯中,加入8.3mL双蒸水,于50℃,400rpm搅拌溶解,边搅拌边加入8.3-16.6mL丙酮,室温静置20min,弃去上清液,加入10mL双蒸水,50℃,200rpm彻底溶解底部沉淀,加入1mol/L的HCl调节pH至2.5;滴加丙酮30-60mL,再加入以戊二醛和丙酮体积比为1:1000配置的溶液2-4mL,室温1000rpm持续搅拌5h,挥发丙酮及戊二醛,用双蒸水稀释10倍,使用40KD透析袋,在双蒸水中透析24h后,在-4℃静置保存。
步骤S6:纳米明胶颗粒包裹卵黄抗体
调节明胶纳米颗粒溶液pH 7.0,向浓度为1mg/mL的纳米颗粒中加入终浓度为45μg/mL卵黄抗体,室温震荡2h后,进行包封率鉴定,检测释放速率。
步骤S7:制备面膜原液
(1)制备Part A:称取体积百分数为6%的1,3-丁二醇、4%的1,2-戊二醇、8%的甘油、2%的泛醇和质量百分数为0.2%的羟乙基纤维素、0.1%的卡波姆、0.2%的黄原胶、0.2%的尿囊素、1%的海藻糖、0.1%的EDTA二钠、0.5%的丝氨酸于烧杯中,混匀备用;
(2)将Part A搅拌,分散均匀至无不溶物,加热至80-85℃,转速为500rpm,保温20min,开始降温;
(3)降温至45℃,加入Part B原料:质量百分数为2%的甜菜碱和0.25%的谷氨酸,搅拌至无不溶物;
(4)加入Part C:质量百分数为0.5%的PEG,至A和B混合液中,搅拌至均匀透明,置于室温条件下,待其正常散热降温;
(5)将Part A、PartB和Part C混合,加入已制备的Part D:纳米卵黄抗体原液,搅拌均匀,三者混合液与Part D的体积比为10:1;
(6)使用300目滤布过滤出料;
(7)基础面膜稳定性测定。
实施例2抗体浓度检测
用BCA法测定一免后10天和35天的IgY浓度。一免后10天的蛋白浓度为4.465μg/mL,一免后35天的蛋白浓度为22.03μg/mL。
实施例3卵黄抗体效价检测
(1)针对菌体抗原的卵黄抗体效价检测
根据图1可知病原菌菌体抗原的特异性IgY的效价于第一次免疫后第6周或第7周达到高峰,其中抗金黄色葡萄球菌特异性卵黄抗体最高效价达到1:4096,且持续维持2周;抗表皮葡萄球菌特异性IgY效价于一免后第7周达到高峰为1:2048;抗痤疮丙酸杆菌特异性IgY效价于一免后第6周达到高峰效价为1:512。
(2)针对蛋白质抗原的卵黄抗体效价检测
根据图2可知病原菌蛋白质抗原的特异性IgY的效价于第一次免疫后第7周或第8周达到高峰,其中抗金黄色葡萄球菌特异性卵黄抗体最高效价达到1:2048;抗表皮葡萄球菌特异性IgY效价于一免后第7周达到高峰为1:1024;抗痤疮丙酸杆菌特异性IgY效价于一免后第7周达到高峰,效价为1:800。
实施例4运用聚丙烯酰胺凝胶电泳(SDS-PAGE)检测蛋白纯度
图3中1号条带和3号条带是水稀释-氯化钠法提取的IgY,通过与market条带比对,虽然存在卵黄抗体但纯度不高,含有大量杂蛋白;4号条带和5号条带是通过水稀释-硫酸铵法提取出的IgY,条带清晰,无拖尾现象,杂蛋白少,卵黄抗体纯度高。水稀释-硫酸铵法优于水稀释-氯化钠法。因此,本发明采用水稀释-硫酸铵法进行卵黄抗体检测。
实施例5体外抑菌实验
最小抑菌浓度(MIC)是微生物对药物敏感性的指标。
表1特异性IgY的MIC值测定结果
实施例6检测纳米明胶颗粒包裹卵黄抗体包封率及释放速度
(1)包封率
计算纳米颗粒包封率为Mn-GNP80.18±1.42%,其中包封率=沉淀中GFP/加入GFP总量×100%。
(2)释放速率
将包裹了卵黄抗体的纳米颗粒,10000rpm离心10min,检测上清液蛋白含量,再取其沉淀用含0.025%胰酶的PBS重悬,在37℃震荡,继续离心后检测不同时间段的上清液的蛋白含量,计算不同时间卵黄抗体的释放率,其中释放率=上清中蛋白含量/总的蛋白含量×100%,根据图5可知,包裹GFP的纳米颗粒,在体外模拟体内环境时,在12h内缓慢释放,在24h时基本完全释放。
实施例7主要面膜配方
(1)1,3-丁二醇
在化妆品中常做保湿剂和溶剂使用,在保湿方面,由于丁二醇是小分子保湿成份,所以抓水比例很小,同时也有一定的抑菌作用。
(2)卡波姆、聚丙烯酸、羧基乙烯共聚物
属于亲水性稠化剂、稳定乳化剂、悬浮剂、凝胶剂,具有良好的透明度。
(3)1,2-戊二醇
1,2-戊二醇在化妆品、护肤品里主要作用是保湿剂,抗菌剂,增溶剂,风险系数为1,比较安全,可以放心使用,对于孕妇一般没有影响,1,2-戊二醇没有致痘性。1,2-戊二醇属于小分子保湿剂,是一种合成保湿剂,在化妆品和美容产品中作溶剂和防腐剂使用,有锁水和抗菌功能,且能提高防晒产品的抗水性。但该成分对眼睛有轻微的刺激,对皮肤无刺激。
(4)甘油
学名丙三醇,一种有机物,由于比较温和没有什么刺激性,它可以有保湿、滋润的作用,还可以在皮肤上形成一种保护膜。所以经常用在皮肤干燥的病人,它还可以做一些药膏或者护肤品的基质,解决皮肤干燥的一些问题。
(5)黄原胶
可作为乳化剂、稳定剂、凝胶增稠剂、浸润剂、膜成型剂等。
(6)羟乙基纤维素
HEC具有良好的增稠、悬浮、分散、乳化、粘合、成膜、保护水分和提供保护胶体等特性。
(7)甜菜碱
易溶于水,清洁污垢;中性稳定,不伤害肌肤;渗透性好;杀菌消炎,可药用。
(8)尿囊素
尿囊素具有促进细胞生长,加快伤口愈合,软化角质蛋白等生理功能,是皮肤创伤的良好愈合剂和抗溃疡药剂。可用作缓解和治疗皮肤干燥症、鳞屑性肤疾患、皮肤溃疡、消化道溃疡及炎症,对骨髓炎、糖尿病、肝硬化、痤疮均有较好疗效。
