摘要: 本研究采用健康肉仔鸡和环磷酰胺免疫抑制肉仔鸡模型,通过体外细胞培养试验来研究2种共轭亚油酸异构体(c9,t11-CLA和t10,c12-CLA)对肉鸡巨噬细胞溶菌酶分泌水平的影响。选取24只1日龄爱拔益加(Arbor Acre )肉仔鸡随机分为免疫抑制处理组和健康肉仔鸡组,分别于14、15和16日龄进行环磷酰胺(cyclophosphamide,CY;80 mg/kg体重)腿肌注射和等体积生理盐水腿肌注射。巨噬细胞体外培养试验采用含不同浓度(0、25、50和100 μmol/L)c9,t11-CLA、t10,c12-CLA或1︰1的混合物(CLA混合物)。结果表明,t10,c12-CLA可减缓CY对巨噬细胞溶菌酶合成和分泌的抑制作用。添加高剂量的t10,c12-CLA效果好于低剂量添加。c9,t11-CLA对巨噬细胞溶菌酶的分泌无明显影响。

Abstract:

The experiment was carried out to study the effects of conjugated linoleic acid (CLA) on lysozyme secretion of 〖HT〗〖ST〗〖WT〗


〖WT5”BZ〗microphages in broilers immunosuppressed with cyclophosphamide (CY).Twenty-four 1-day-old male Arbor Acre broiler chickens were randomly allocated into 2 treatments,with or without CY injection. CY was injected into the femoral muscle of broilers at a dose of 80 mg/kg of body weight for three consecutive days (days 14,15 and 16).On day 21,the peritoneal exudate macrophages from 12 broilers per treatment were collected for in vitro culture. The different levels (0,25,50 and 100 μmol/L) of two CLA isomers (c9,t11-CLA and t10,c12-CLA) and their mixture (50/50) were used for the macrophage in vitro culture. The results showed that t10,c12-CLA alleviated the suppressed effects of CY on the secretion of lysozyme of macrophages,and the higher t10,c12-CLA supplementation had better effects.But c9,t11-CLA had no significant influence on lysozyme contents of macrophages.
