Description
技术领域
本发明涉及保健食品领域,特别涉及一种组合物及其应用。
背景技术
由于男性因素而导致的不孕不育症称男性不育症,男性不育症是一种发病率较高且较难治愈的病症。国内外目前研究资料表明:不孕不育症在育龄期夫妇中的发病率约为15%-20%,根据世界卫生组织统计:全球大约有600-8000万对夫妇患有不同程度的不育症,其中由男性因素导致的不育约占所有不育夫妇的50%。
中国人口基数大,且相对世界水平发病几率较高,近年来也呈上升趋势。不育症往往造成夫妻感情不和,婚姻家庭破裂,给社会带来不稳定因素。男性不育的病因多种多样,最常见且最直接的外在表现为精液品质下降。目前我国医药技术领域在治疗男性不育症方面积累了较为丰富的经验,有西医治疗,如采用药物、手术、局部用药等,也有许多有效的中成药,如补肾种子方、补肾生精丸、温肾丸、育精丸等,虽然这些治疗方法在治疗不育症方面各有其优点,但是每种方法都存在一定的局限性。且药物治疗持续时间长,并伴有众多副作用,手术治疗创伤大。且由于中华民族的传统,人们更愿意优先选择食补。因此,提供一种效果显著、无副作用、能改善精液质量、加快男性精子形成、提高生育能力的组合物及保健食品具有重要的现实意义。
发明内容
有鉴于此,本发明提供了一种组合物及其应用,该组合物科学有效,无副作用,能改善精液质量,加快男性精子形成,提高生育能力。
为了实现上述发明目的,本发明提供以下技术方案:
本发明提供了N-乙酰氨基葡萄糖在制备提高精液数量、缩短精液液化时间、增加精子密度或提高精子活力的药物或保健食品中的应用。
本发明还提供了N-乙酰氨基葡萄糖在制备提高男性生殖能力的药物或保健食品中的应用。
本发明还提供了一种组合物,包括N-乙酰氨基葡萄糖和左旋肉碱。
在本发明的一些具体实施方案中,所述N-乙酰氨基葡萄糖和所述左旋肉碱的质量比为(300~7500):(340~8500)。
在本发明的一些具体实施方案中,本发明提供的组合物还包括维生素E、锌、硒或精氨酸中的一种或多种。
在本发明的一些具体实施方案中,以质量份计,本发明提供的组合物包括如下组分:

在本发明的一些具体实施方案中,以质量份计,本发明提供的组合物包括如下组分:
本发明还提供了所述的组合物在制备提高精液数量、缩短精液液化时间、增加精子密度或提高精子活力的药物或保健食品中的应用。
本发明还提供了所述的组合物在制备改善男性生殖能力的药物或保健食品中的应用。
N-乙酰氨基葡萄糖以及本发明提供的组合物能够增加精子发生,促进精子发生和成熟,为精子供能,增加精子活力,保护精子细胞膜的完整性,增加精子DNA稳定性,全面提升精液品质,故能收到满意效果。
试验表明,本发明提供的组合物、药物或保健食品能够提高精液数量、缩短精液液化时间、增加精子密度、提高精子活力,显著改善男性生殖能力。
本发明提供的组合物在添加辅料后制成片剂或胶囊作为药物或保健食品,服用方法为:口服,一次1片,一日1次,晨起顿服(或遵医嘱)。每个疗程30天。轻者服2~3个疗程,重者服4~5个疗程。
本发明提供的组合物、药物或保健食品功效显著,具有以下优点:1)疗效较好,服用后能促进睾丸曲细精管间质细胞功能改善、增强性机能、促进精子生成、提高精子活力,有效提高生育能力;2)适用范围广,适用于各种年龄人群,尤其是对因年龄增大导致生育能力下降有较好疗效,且无明显副作用。

使用50mg/kg ZEA塑造少弱精症小鼠模型,使用目前公认有效的维生素E作为阳性对照组。维生素E的添加方法为每公斤饲料添加12g维生素E,ZEA溶液均溶解于0.1%DMSO。选择出生后21天的雄性CD-1小鼠80只,随机分为四组,自出生后21天开始每天固定时间经口灌胃饲喂溶液,42天后安乐死,之后进行一系列的实验。对照组仅饲喂含0.1%DMSO的液体,ZEA组饲喂50mg/kgZEA,ZEA+N-GlcNAc组饲喂50mg/kg ZEA和25μg/kg N-GlcNAc,ZEA+维生素E组饲喂50mg/kg ZEA和含有维生素E的饲料。
小鼠经安乐死后,取小鼠附睾尾剪开后收集精液,制备成精子悬液,使用Computer-aided sperm analysis(CASA)进行精子活力和精子浓度的分析;使用凋亡和坏死检测试剂盒进行精子死亡率的分析。
精子顶体反应实验为将不同浓度的N-GlcNAc聚合物加入体外培养的精子中,使用免疫荧光染色的方法观察精子的顶体反应发生率。使用(化合物顶体反应率-阴性对照组顶体反应率)/(阳性对照组顶体反应率-阴性对照组顶体反应率)计算标准化的顶体反应发生率。
结果分析:
图1~图3对应的原始数据见表1。
表1
精子活力(%) | 精子密度(百万/毫升) | 精子死亡率(%) | |
Control | 70.4±6.7 | 2092.2±85.1 | 45.1±3.5 |
ZEA | 35.2±11.9abc | 766.4±209.8abc | 77.7±3.4abc |
ZEA+N-GlcNAc | 66.7±9.5 | 1790.3±199.7 | 47.5±4.3 |
ZEA+维生素E | 63.0±7.4 | 1749.8±202.6 | 49.0±4.2 |
a:与对照组相比,P<0.05;b:与ZEA+N-GlcNAc组相比,P<0.05;c:与ZEA+维生素E组相比,P<0.05;
精子活力:如表1、图1所示,较其他三组而言,使用50mg/kg ZEA饲喂的小鼠的精子活力出现显著的下降趋势,而合用ZEA和经典药物维生素E的小鼠精子活力显著改善,与阴性对照组相比没有明显差异。使用ZEA和N-GlcNAc的小鼠的精子活力较ZEA组同样出现显著的改善,同阴性对照组和ZEA+维生素E组没有明显的差异,说明N-GlcNAc能够显著改善精子活力。
精子密度:如表1、图2所示,较其他三组而言,使用50mg/kg ZEA饲喂的小鼠的精子密度出现显著的下降趋势,而合用ZEA和经典药物维生素E的小鼠精子密度显著上升,与阴性对照组相比没有明显差异。使用ZEA和N-GlcNAc的小鼠的精子密度较ZEA组同样出现显著的上升,同阴性对照组和ZEA+维生素E组没有明显的差异,说明N-GlcNAc能够显著增加精子密度。
精子死亡率:如表1、图3所示,较其他三组而言,使用50mg/kg ZEA饲喂的小鼠的精子死亡率出现显著的上升趋势,而合用ZEA和经典药物维生素E的小鼠精子死亡率显著降低,与阴性对照组相比没有明显差异。使用ZEA和N-GlcNAc的小鼠的精子死亡率较ZEA组同样出现显著的降低,同阴性对照组和ZEA+维生素E组没有明显的差异,说明N-GlcNAc能够显著降低精子死亡率。
精子顶体反应:见表2。
表2
浓度 | 标准化顶体发生率(%) |
1μmol/L | -9.2±5.3 |
5μmol/L | 81.2±3.5a |
10μmol/L | 83.2±4.6a |
20μmol/L | 52.3±7.7a |
a:与1μmol/L组相比,P<0.05.
表2为不同浓度的N-GlcNAc添加到精子培养液中后,精子顶体反应发生率的变化。表2中使用到的是标准化的顶体反应率,即(化合物顶体反应率-阴性对照组顶体反应率)/(阳性对照组顶体反应率-阴性对照组顶体反应率)。由表2结果可见,不同浓度的N-GlcNAc可以明显的提高精子的顶体反应发生率。
