TP 5000:Lieber-DeCarli 71%高脂模型飼料
Lieber-DeCarli Diet with 71% High Fat

飼料代碼TP 5000是Lieber-DeCarli液體型71%高脂模型飼料,適用于大鼠和小鼠。

Lieber和DeCarli首先研究出36%高脂酒精液體飼料建立酒精性脂肪肝模型(AFLD)飼料,由于該飼料是至今仍廣為使用,這就是經典而聞名的Lieber-DeCarli酒精液體飼料。該36%酒精液體飼料的對照飼料是36%高脂飼料,也就是說,模型飼料和對照飼料都是36%高脂肪,不同的是模型飼料中有酒精,對照飼料沒有酒精。

Lieber-DeCarli 71%高脂模型飼料的特點

(1)Lieber等作者的研究表明,用于建立非酒精性脂肪肝的速度非常快,只需要幾周。脂肪肝為全小葉性,伴有單核細胞浸潤(炎癥),線粒體損傷,氧化應激,腫瘤壞死因子升高,I型膠原纖維和前膠原mRNA增加,胰島素升高。

(2)飼料為液體型。研究者可以自行向液體飼料中任意添加藥物、食物提取物或其他功能因子。這是固體型飼料無法做到的。

(3)改變脂肪類型,可以研究不同脂肪(不同脂肪酸構成)對NSAH(NAFLD)形成和干預的作用。

后來,Lieber和DeCarli又轉向研究建立非酒精性脂肪肝模型(NAFLD, NASH)模型,方法是在對照飼料36%高脂基礎上將脂肪熱量提高到71%,碳水化合物熱量相應減少到11%,蛋白質熱量不改變(18%),并且仍使用液體型飼料喂養。這個模型飼料喂養SD大鼠后,非酒精性脂肪肝發展很快,幾周就非常明顯,不僅肝臟病理表現與人類相似,而且伴有高胰島素血癥(胰島素抵抗)、腫瘤壞死因子(TNF)等一系列生化指標的改變。

奇怪的是,后來國外有一篇SCI論文,質疑該模型飼料能否引起非酒精性脂肪肝。

然而,后來有些研究者使用該飼料都成功復制出來了非酒精性脂肪肝模型,并且病理表現和生化指標的改變都得到重復和驗證。有的研究者在基因敲除的小鼠中也建模成功。

南通特洛菲飼料科技有限公司按照作者提供的信息進行科學配比,飼料代碼TP5000,對照飼料是TP 4030C,或標準對照TP4010、TP4012。供廣大研究者進行非酒精性脂肪肝的研究。
