2021世界燕窩展|上海滋補(bǔ)品展談燕窩抗氧化,抗炎和抗衰老作用?
衰老是不可避免的,但延緩衰老卻是可能的。目前的研究發(fā)現(xiàn),在衰老機(jī)體中,除了含有大量自由基,氧化應(yīng)激水平高之外,許多炎癥因子如IL-1、腫瘤壞死因子(tumor necrosis factor,TNF)、干擾素等含量也有所增高。下丘腦內(nèi)核因子-κβ(NF-κβ)的表達(dá)可導(dǎo)致促性腺素釋放素(gonadotropin releasing hormone,GnRH)分泌減少,從而促進(jìn)機(jī)體的衰老。通過(guò)藥物或基因操作抑制NF-κβ可使衰老小鼠趨于年輕化。如長(zhǎng)期服用阿司匹林可延長(zhǎng)小鼠壽命,促進(jìn)人體的健康老化。


2021第五屆世界燕窩及天然滋補(bǔ)品展覽會(huì)(簡(jiǎn)稱(chēng)上海燕博會(huì))于8月25-27日在上海新國(guó)際博覽中心盛大召開(kāi);匯集燕窩及高端滋補(bǔ)品行業(yè)上千家品牌匯聚,目前已成為燕窩及滋補(bǔ)品行業(yè)影響力、規(guī)模、專(zhuān)業(yè)性領(lǐng)先的行業(yè)盛會(huì),圍繞“共創(chuàng)養(yǎng)生新時(shí)代,成就滋補(bǔ)大未來(lái)”;推動(dòng)健康行業(yè)有序發(fā)展。
用HaCaT細(xì)胞研究燕窩對(duì)氧化應(yīng)激誘導(dǎo)的基質(zhì)金屬蛋白酶-1(MMP-1)的影響,發(fā)現(xiàn)燕窩水提物可以抑制H?O?誘導(dǎo)的細(xì)胞毒性和消除細(xì)胞內(nèi)的活性氧自由基,下調(diào)H?O?誘導(dǎo)的MMP-1mRNA、蛋白表達(dá)和活性,降低細(xì)胞外調(diào)節(jié)蛋白激酶 (ERK)和c-Jun氨基末端激酶 (JNK)的活化。此外還可以抑制c-Fos和磷酸化c-Jun蛋白的表達(dá)。表明燕窩抗衰老的活性與通過(guò)下調(diào)ERK/JNK和激活蛋白-1(AP-1)的通路來(lái)抑制MMP-1的表達(dá)有關(guān)(Kim,2012)。
燕窩具有抗氧化性,并具有生物活性自由基清除劑的作用。在體外試驗(yàn)中,分子量小于3千道爾頓(1道爾頓Da=1000摩爾質(zhì)量g/mol)的部分表現(xiàn)出最高的生物活性。燕窩能延緩果蠅的衰老,其主要原因是果蠅體內(nèi)抗氧化酶活性增加,脂質(zhì)過(guò)氧化產(chǎn)物含量降低(Ghassem,2017)。
通過(guò)珍珠燕窩提取液的功效研究發(fā)現(xiàn),提取液明顯降低了小鼠腦組織的脂質(zhì)過(guò)氧化作用和大大提高了大鼠紅細(xì)胞中超氧化物歧化酶的水平,具有消除氧自由基,延緩了衰老作用(Zhang,1994)。燕窩中的不飽和脂肪酸對(duì)燕窩的抗氧化作用具有重要貢獻(xiàn)(Lee,2019)。

燕窩可以增加非妊娠大鼠的抗氧化劑和總抗氧化劑能力,并降低氧化應(yīng)激水平(Albishtue,2018)。此外,它還可以通過(guò)維持抗氧化劑-活性氧物平衡和調(diào)節(jié)相關(guān)基因的綜合機(jī)制(Albishtue,2019)。燕窩提取物能抑制TNF-α(腫瘤壞死因子)和一氧化氮的形成,最高抑制率分別為58%和63%,過(guò)程中未發(fā)現(xiàn)明顯的細(xì)胞毒副作用(Vimala,2012)。
研究結(jié)果表明,與陽(yáng)性對(duì)照辛伐他汀相比,燕窩可部分通過(guò)對(duì)肝臟抗氧化和抗炎癥相關(guān)基因的轉(zhuǎn)錄調(diào)節(jié),減輕高脂飲食引起的氧化應(yīng)激和炎癥。結(jié)果還表明,其轉(zhuǎn)錄機(jī)制可能與燕窩的抗氧化和抗炎作用有關(guān)(Zhang,2015)。
