ABSTRACT
Objective To explore the dosage and injection method of concanavalin A(Con A) for inducing Wistar rats into the acute hepatic injury model. Methods (1)According to the dosage of Con A, 42 Wistar rats were randomly divided into groups A, B, C, D, E, N, 7 rats in each group. Group N was given tail intravenous injection of normal saline as normal control group. Groups A, B, C, D, E were given intravenous injection of 4, 8, 16, 30, 40 mg/kg of Con A respectively. At the 8th hour after modeling, the levels of alanine transaminase(ALT), aspartate aminotransferase(AST), albumin(ALB), interleukin(IL)-2 , IL-10, interferon (IFN)-γ, and tumor necrosis factor(TNF)-αwere detected. And HE staining was used to observe the pathological feature of hepatic tissue. (2)According to the injection method of Con A, 21 Wistar rats were randomly divided into normal control group, intraperitoneal injection group and tail intravenous injection group, 7 rats in each group. The dosage of Con A for the rats in intraperitoneal injection group and tail intravenous injection group was 16 mg/kg. At the 8th hour after modeling, the levels of serum ALT, AST, and ALB were determined. Results The number of abnormal deaths in various dose Con A groups at the end of each experiment was 0 in groups A, B, C, and 2 in group D, and 7 in group E. A small amount of spotty necrosis, inflammatory cell infiltration, and hepatic lobule with almost integrity of structure were found in groups A, B, while obvious bridging-like necrosis was seen in groups C, D. Serum ALT, AST, and ALB levels in intraperitoneal injection group had no statistically significant difference as compared with the normal control group. Conclusion Tail intravenous injection of 16 mg/kg of Con A can be used to induce an acute immunological liver injury rat model successfully.
