| 1 | Effect of propranolol on the splanchnic and peripheral renin angiotensin system in cirrhotic patients显示文摘AIM:To evaluate the effect of β-blockade on angiotensins in the splanchnic and peripheral circulation of cirrhotic patients and also to compare hemodynamic parameters during liver transplantation according to propranolol pre-treatment or not. METHODS:Patients were allocated into two groups:outpatients with advanced liver disease(LD) and during liver transplantation(LT). Both groups were subdivided according to treatment with propranolol or not. Plasma was collected through peripheral venipuncture to determine plasma renin activity(PRA),Angiotensin(Ang) Ⅰ,Ang Ⅱ,and Ang-(1-7) levels by radioimmunoassay in LD group. During liver transplantation,hemodynamic parameters were determined and blood samples were obtained from the portal vein to measure renin angiotensin system(RAS) components.RESULTS:PRA,Ang Ⅰ,Ang Ⅱ and Ang-(1-7) were signifi cantly lower in the portal vein and periphery in all subgroups treated with propranolol as compared to non-treated. The relationships between Ang-(1-7) and Ang Ⅰ levels and between Ang Ⅱ and Ang Ⅰ were significantly increased in LD group receiving propranolol. The ratio between Ang-(1-7) and Ang Ⅱ remained unchanged in splanchnic and peripheral circulation in patients under β-blockade,whereas the relationship between Ang Ⅱ and Ang Ⅰ was significantly increased in splanchnic circulation of LT patients treated with propranolol. During liver transplantation,cardiac output and index as well systemic vascular resistance and index were reduced in propranolol-treated subgroup. CONCLUSION:In LD group,propranolol treatment reduced RAS mediators,but did not change the ratio between Ang-(1-7) and Ang Ⅱ in splanchnic and peripheral circulation. Furthermore,the modification of hemodynamic parameters in propranolol treated patients was not associated with changes in the angiotensin ratio. | Walkíria Wingester Vilas-Boas Antnio Ribeiro-Oliveira Jr Renata da Cunha Ribeiro Renata Lúcia Pereira Vieira Jerusa Almeida Ana Paula Nadu Ana Cristina Sim■es e Silva Robson Augusto Souza Santos | 2008 | World Journal of Gastroenterology2008，14，44： | 2 |

| 12 | 黄粉虫替代蛋白质饲料对太平洋白虾(凡纳滨对虾)消化性能的影响显示文摘试验旨在评估黄粉虫粉(MM)作为凡纳滨对虾养殖中蛋白质来源的可行性。饲料分为正常饲料和试验饲粮,试验饲料中包含正常饲料85%和MM 15%,两种饲料中均含有氧化铬0.5%作为惰性标记,试验采用表观消化率系数(ADC)对两种饲料进行检测。为评估MM消化价值,对虾饲料中采用鱼粉替代MM,替代比例分别为0%、25%、50%、75%和100%,在清水中饲养6周后,对生长参数和整个虾体成分进行评估。干物质ADC为45.9%,能量ADC为66.5%,粗蛋白质ADC为76.1%,必须氨基酸ADC为72%~86%。MM中蛋氨酸为第一限制性氨基酸。饲料中添加MM后,各组间对虾的体增重、特定生长率、采食量、饲料转化率、存活率和蛋白质合成率均无显著变化(P>0.05),虾体蛋白质含量无显著差异(P>0.05)。而随着鱼粉替代比例上升,虾体脂含量从1.13%升至1.88%。结果表明,黄粉虫粉可作为凡纳滨对虾饲料中的替代蛋白质饲料,但添加时应注意补充蛋氨酸。 | Panini R L Freitas L E L Guimarǎes A M Rios C da Silva M F O Vieira F N Fracalossi D M Samuels R I | 2017 | 饲料博览2017，0，7： | 1 |
