Egr-1 mRNA and Egr-1 protein hadn't been found in the normal vein. The expressions of Egr-1 mRNA and Egr-1 protein had biphasic changes. By reverse transcription-PCR and in situ hybridization, we found that the level of Egr-1 mRNA rose at 1 hour after graft, the expression of Egr-1 mRNA was (35±7)%. Decline at hour 6, 24 and day 3, the positive rates of Egr-1 mRNA were (8±2)%,(8±6)% and (8±4)% respectively. Reincrease at day 7, a peak at day 28, the positive rate of Egr-1 mRNA was (45±6)%(compared with other phase, P＜0.01). At day 42, the expression of Egr-1 mRNA declined again. Immunohistochemical staining and Western blot revealed Egr-1 protein had expressed at hour 2 early phase, the expression of Egr-1 protein was (30±5)%, and until to hour 6. The level of Egr-1 protein was decrease at hour 24 and day 3, the positive rates were (7±3)% and (7±8)% respectively.

METHODS: Female BALB/c mice were treated with CCK-8 and keyhole limpet haemocyanin, splenocytes were acquired and incubated in vitro with KLH restimulation, the productions of Th1 cytokines, interferon-γ, interleukin-2 and Th2 cytokines, IL-4, IL-5 in cell culture supernatants were detected by enzyme-linked immunosorbnent assay. The mRNA expressions of IFN-γ, IL-2, IL-4 and IL-5 in splenocytes were detected by reverse transcription-polymerase chain reaction. The levels of Th1 antibody IgG2a and Th2 antibodies IgG1 in serum were also detected by ELISA.
