Objective To study the change of interleukin 1 β gene transcription in the animal model of hypoxic ischemic brain damage(HIBD).Methods A model of HIBD in left brain of neonate rats was established and IL 1 β mRNA in the lesioned ischemic cortex and hippocampus at different times by DNA RNA Dot blot hybridization with IL 1 β oligonucleotide probe was detected.Results Dot blot hybridization was sensitive and specific.The probe can detect 1pg of total RNA,and hybridize only to the homologous nucleic acid.Level of IL 1 β mRNA was elevated as early as 1 hour and peaking expression was 3 hour after HIBD,IL 1 β expression in hippocampus was higher than that in cortex.Conclusions IL 1 β gene expression appears early after HIBD,it may play an important role in the response of inflammatory to HIBD.
