目的

探索硫代乙酰胺(Thioacetamide,TAA)诱导的比格犬肝损伤时F4/80、白细胞介素6(Interleukin-6,IL-6)与胰岛素样生长因子结合蛋白相关蛋白1(insulin-like growth factor binding protein-related protein1,IGFBP-rP1)的表达变化。

方法

将12只雄性比格犬按随机数字表法分为正常对照组和TAA 6周组,每组6只,观察肝组织形态学改变,免疫组织化学染色检测F4/80与IGFBPrP1的表达,ELISA检测血浆IL-6与IGFBPrP1的水平,Western blot检测IGFBPrP1蛋白的表达。

结果

HE染色结果显示TAA组肝细胞变性、坏死,炎细胞浸润增多。F4/80的免疫组织化学染色结果显示TAA组肝组织枯否细胞内可见大量棕褐色颗粒,表达较正常对照组明显增强(3.14±0.01 vs. 0.10±0.02,P<0.05)。IL-6的ELISA结果显示TAA组血浆IL-6水平较正常对照组显著增高(26.00±2.90 vs. 16.8±4.10,P<0.05)。IGFBPrP1的免疫组织化学染色结果显示TAA组肝组织肝窦、血管壁、汇管区及部分肝细胞内可见大量棕褐色颗粒沉积,表达明显高于正常对照组(1.69±0.01 vs. 0.50±0.06,P<0.05)。IGFBPrP1的Western blot结果显示TAA组IGFBPrP1蛋白的表达较正常对照组显著增多(P<0.05)。IGFBPrP1的ELISA结果表明TAA组血浆IGFBPrP1水平较正常对照组显著增高(1.54±0.08 vs. 1.09±0.05,P<0.05)。

结论

比格犬肝损伤时F4/80、IL-6与IGFBPrP1均发生了明显变化,表明其参与了肝损伤的过程。

Objective

To explore the expression changes of F4/80, interleukin-6(IL-6)and insulin-like growth factor binding protein-related protein 1(IGFBPrP1)in liver injury induced by thioacetamide(TAA)in beagles.

Methods

Twelve male beagles were randomly divided into two groups(n=6 in each group)using random number table method: normal group and TAA group(6 weeks). The morphological changes of liver tissues were observed.The expressions of F4/80 and IGFBPrP1 were detected by immunohistochemisty staining.The levers of IL-6 and IGFBPrP1 in plasma were detected by enzyme-linked immuno sorbent assay(ELISA). The protein expression of IGFBPrP1 was detected by Western blotting.

Results

In TAA group, hematoxylin-eosin(HE)staining results showed that there was hepatocyte degeneration, necrosis and infiltration of inflammatory cells.The results of immunohistochemisty staining showed that there were a large number of brown granules in Kupffer cells in TAA group, and the expression of F4/80 in TAA group was significantly increased compared with normal group(3.14±0.01 vs. 0.10±0.02, P<0.05). The plasma lever of IL-6 in TAA group was higher than that in normal group(26.00±2.90 vs. 16.8±4.10, P<0.05). The results of immunohistochemisty staining showed that there were a large number of brown granules in hepatic sinusoid, vascular wall, portal area and part of hepatic cells in TAA group, and the expression of IGFBPrP1 in TAA group was increased markedly compared with normal group(1.69±0.01 vs. 0.50±0.06, P<0.05). The Western blotting results showed that the lever of IGFBPrP1 in TAA group was higher than that in normal group(P<0.05). The ELISA results showed the plasma lever of IGFBPrP1 in TAA group was higher than that in normal group(1.54±0.08 vs. 1.09±0.05, P<0.05).

Conclusion

The expressions of F4/80, IL-6 and IGFBPrP1 change obviously in liver injury in beagles, which indicates all of them may involve in the process of liver injury.
