| 1 | 枯草芽孢杆菌及饲料粗蛋白质水平对肉鸡生长性能和肉鸡肠道形态的影响显示文摘试验通过检测肉鸡生长性能、胴体品质、肉品质和消化道发育情况、回肠CP消化率,探究日粮中添加枯草芽孢杆菌对肉鸡粗蛋白质(CP)需求量的影响。试验选取720只1日龄肉鸡。设置2×2方阵设计,包括按照标准CP水平设置的对照组(CP 100),在标准基础上降低2%CP含量的试验组(CP 98);不添加枯草芽孢杆菌组及添加枯草芽孢杆菌0.2 g·kg^(-1)组(0.8×10~9cfu·g^(-1),将肉鸡随机分配到各组。每组6个重复,每个重复30只肉鸡。育雏料、生长期饲料和育肥期饲料均按照标准制定,饲料中添加枯草芽孢杆菌对生长性能无显著影响。然而,随着日粮中CP水平下降,体增重和饲料效率显著下降(P<0.05),饲料中添加枯草芽孢杆菌可显著提高肉鸡胴体品质(P<0.05)。添加枯草芽孢杆菌对肉品质无显著影响,然而,随着日粮中CP含量下降,肉的保水力显著下降(P<0.05);空肠隐窝显著变深(P<0.05),回肠CP消化率显著提高(P<0.05)。试验结果表明,日粮中添加枯草芽孢杆菌可改善空肠形态,减缓日粮中CP含量减少的不利影响。因此,益生菌的使用可改变胃肠道形态特征,提高CP的回肠消化率,提高饲料效率。 | Mahmoud K Z Obeidat B S Al-Sadi M Z Hatahet Sh R | 2017 | 饲料博览2017，0，1： | 5 |
| 2 | Haemoxygenase modulates cytokine induced neutrophil chemoattractant in hepatic ischemia reperfusion injury显示文摘AIM To investigate the hepatic microcirculatory changes due to Haemoxygenase(HO),effect of HO inhibition on remote ischemic preconditioning(RIPC) and modulation of CINC.METHODS Eight groups of animals were studied- Sham,ischemia reperfusion injury(IRI) the animals were subjected to 45 min of hepatic ischemia followed by three hours of reperfusion,RIPC(remote ischemic preconditioning) + IRI group,remote ischemic preconditioning in sham(RIPC + Sham),PDTC + IR(Pyridodithiocarbamate,HO donor),Zn PP + RIPC + IRI(Zinc protoporphyrin prior to preconditioning),IR-24(45 min of ischemia followed by 24 h of reperfusion),RIPC+IR-24(preconditioning prior to. After 3 and 24 h of reperfusion the animals were killed by exsanguination and samples were taken. RESULTS Velocity of flow(160.83 ± 12.24 μm/s),sinusoidal flow(8.42 ± 1.19) and sinusoidal perfusion index(42.12 ± 7.28) in hepatic IR were lower(P < 0.05) in comparison to RIPC and PDTC(HO inducer). RIPC increased velocity of flow(328.04 ± 19.13 μm/s),sinusoidal flow(17.75 ± 2.59) and the sinusoidal perfusion index(67.28 ± 1.82)(P < 0.05). PDTC(HO induction) reproduced the effects of RIPC in hepatic IR. PDTC restored RBC velocity(300.88 ± 22.109 μm/s),sinusoidal flow(17.66 ± 3.71) and sinusoidal perfusion(82.33 ± 3.5) to near sham levels. Zn PP(HO inhibition) reduced velocity of flow of RBC in the RIPC group(170.74 ± 13.43 μm/s and sinusoidal flow in the RIPC group(9.46 ± 1.34). Zn PP in RIPC(60.29 ± 1.82) showed a fall in perfusion only at 180 min of reperfusion. Neutrophil adhesion in IR injury is seen in both postsinusoidal venules(769.05 ± 87.48) and sinusoids(97.4 ± 7.49). Neutrophil adhesion in RIPC + IR injury is reduced in both postsinusoidal venules(219.66 ± 93.79) and sinusoids(25.69 ± 9.08)(P < 0.05). PDTC reduced neutrophil adhesion in both postsinusoidal venules(89.58 ± 58.32) and sinusoids(17.98 ± 11.01)(P < 0.05) reproducing the effects of RIPC. Zn PP(HO inhibition) increased venular(589.04 ± 144.36) and sinusoidal neutrophil adhesion in preconditioned animals(121.39 ± 30.65)(P < 0.05). IR after 24 h of reperfusion increased venular and sinusoidal neutrophil adhesion in comparison to the early phase and was significantly reduced by RIPC. Hepatocellular cell death in IRI(80.83 ± 13.03),RIPC + IR(17.35 ± 2.47),and PTDC+IR(11.66 ± 1.17) Zn PP + RIPC + IR(41.33 ± 3.07) reduced hepatocellular death. Zn PP significantly increased hepatocellular death(P < 0.05 PTDC/RIPC vs Zn PP and IR). The CINC cytokine levels in sham(101.32 ± 6.42). RIPC + sham(412.18 ± 65.24) as compared to sham(P < 0.05). Hepatic IR(644.08 ± 181.24)(P < 0.05). RIPC CINC-1 levels in the early phase(401.62 ± 78.56). And PDTC(HO inducer) CINC-1 levels in hepatic IR(413.36 ± 63.06) were significantly lower. HO inhibition in preconditioned animals with Zinc protoporphyrin increased serum CINC levels(521.81 ± 74.9)(P < 0.05). The serum CINC levels were high in the late phase of hepatic IR(15306 ± 1222.04). RIPC reduced CINC levels in the late phase of IR(467.46 ± 26.06),P < 0.05.CONCLUSION RIPC protects hepatic microcirculation by induction of HO and modulation of CINC in hepatic IR. | Niteen Tapuria Sameer Junnarkar Mahmoud Abu-amara Barry Fuller Alexander M Seifalian Brian R Davidson | 2016 | World Journal of Gastroenterology2016，22，33： | 3 |
