摘 要: | 以黄颡鱼(Pelteobagrus fulvidraco)(14.23±0.65) g为实验对象, 分别饲喂3组等氮饲料(C组: 组胺含量147 mg/kg; H组: 479 mg/kg和H+B组: 496 mg/kg+1×105 CFU/g罗伊氏乳杆菌Lactobacillus reuteri), 进行56d的养殖实验, 研究组胺及罗伊氏乳杆菌对黄颡鱼的影响。结果显示, H+B组血清谷丙转氨酶(ALT)及谷草转氨酶(AST)活力显著低于H组(P<0.05), 而与C组无差异(P>0.05); H+B组肝脏谷胱甘肽S转移酶(GSH-ST)活力及丙二醛(MDA)含量显著低于H组(P<0.05), 与C组无差异(P>0.05); 肝脏HE染色显示, H组肝脏中有较多炎症细胞浸润, 而H+B组肝脏细胞结构完整, 无明显损伤; 肠道HE染色显示, H组肠道皱襞数量明显减少、长度显著变短, 有水肿发生, 而H+B组肠道皱襞数量、长度与对照组无差异, 水肿程度不明显。结果表明: 组胺会引起黄颡鱼肝脏、肠道损伤, 而罗伊氏乳杆菌对组胺引发的肝肠损伤有保护功效。

THE ENTEROHEPATIC PROTECTION OF PELTEOBAGRUS FULVIDRACO ADDING LACTOBACILLUS REUTERI INDUCED BY HISTAMINE |

Abstract: | To investigate the effects of histamine and Lactobacillus reuteri on Pelteobagrus fulvidraco, three isonitrogenous diets, namely diet C (control, with a 147 mg/kg content of histamine), diet H (with a 479 mg/kg content of histamine) and diet H+B (histamine+ bacteria: a 496 mg/kg content of histamine and 1×105 CFU/g L. reuteri), were formulated for a 56-day trial of P. fulvidraco juveniles (14.23±0.65) g. Our data indicated that plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity were significantly lower in group H+B compared with those of group H (P<0.05), while there was no significant difference between group H+B and group C (P>0.05). Meanwhile, liver glutathione-s-transferase (GSH-ST) activity and malondialdehyde (MDA) content were dramatically reduced in group H+B compared with those of group H (P<0.05), while there was no significant difference between group H+B and group C (P>0.05). Furthermore, the HE staining showed that there were inflammatory cells infiltrating in the liver of fish fed with diet H, while no hepatocyte abnormality observed in group C and group H+B, and that the intestinal folds decreased significantly with shorter and edema in diet H group, while this is no marked difference in the length of intestinal folds between group C and H+B. Overall, our studies indicated the protective effect ofL. reuteri against histamine in cultured fish diet. |
