摘要:

为研究腹水综合征(AS)肉鸡肺组织NO、ET-1及相关指标变化和复方中药对其的防治作用,将316羽14日龄罗斯肉鸡随机分为空白组(N组,常温,常规饲养)、模型组(C组,9~11 ℃,添加3%猪油和4%鱼粉的高能饲料,0.12% Na+饮水饲养)和复方中药高(T1)、中(T2)、低(T3)剂量组(饲养同C组,每天于饮水中分别给予2、1、0.5 mL•kg-1复方中药)以及L-Arg组(L组,饲养同C组,每天于饲料中添加1% L-Arg)。结果表明:与N组相比,35和45日龄C组肉鸡出现典型临床症状,腹水发病率、腹水心脏指数和肺组织NO及ET-1含量、iNOS活性、ETAR mRNA相对表达量显著增加(P<0.01或P<0.05),肺组织cNOS活性和NO/ET-1显著降低(P<0.01);与C组相比,T1、T2和L组均能改善临床症状及上述指标(P<0.01或P<0.05)。肉鸡肺组织NO及ET-1含量、ETAR mRNA相对表达量和iNOS活性升高,cNOS活性降低,导致NO、ET-1失衡,参与了AS的发生;气血双补、行气利水的复方中药能有效防治AS。

Abstract:

The objective of this study was to investigate the changes of the contents of nitric oxide (NO) and endothelin-1 (ET-1),and the related items in lung of broilers with ascites syndrome (AS) and the prevention and treatment of the compound recipe of the traditional Chinese medicine on AS.A total of 316 14-day-old Ross broilers were randomly divided into normal group (N,bred with a standard diet at room temperature),control group (C,bred with high-energy diet derived from standard diet added with 3% lard and 4% fish meal and 0.12% Na+ in drinking water at 9-11 ℃ to induce AS),compound recipe of the traditional Chinese medicine groups (T1,T2,T3,bred in the same way as group C except a dose of 2,1,0.5 mL•kg-1 bw of the traditional Chinese medicine everyday added in drinking water,respectively),and L-arginine group (L,bred in the same way as group C except 1% L-arginine added in diet).The results showed that the broilers in group C presented the typical clinical symptoms of AS at 35 and 45 days of age.Compared with group N,the incidence of AS,ascites heart index (AHI),the contents of NO and ET-1,iNOS activity and the relative expression amount of ETAR mRNA in lung of broilers at 35 and 45 days of age in group C were increased significantly (P<0.01 or P<0.05),and cNOS activity and the ratio of NO to ET-1 were decreased significantly (P<0.01) in group C.The clinical symptoms and items mentioned above were all improved in groups of L,T1 and T2 compared with group C (P<0.01 or P<0.05).The study showed that the increases of NO and ET-1 content,ETAR mRNA relative expression amount and iNOS activity and the decrease of cNOS activity in lung of broiler induced the unbalance of NO and ET-1 which participated in the pathogenesis of AS.The studied compound recipe of the traditional Chinese medicine with the role of tonifying qi-blood and activating qi to excrete water can prevent and treat AS of broiler effectively.
