目的  探討地塞米松治療急性壞死性胰腺炎(ANP)的機(jī)理。
方法  經(jīng)胰膽管逆行注射牛磺膽酸鈉法誘導(dǎo)SD大鼠ANP,治療組(n=24)模型誘導(dǎo)30 min后注射地塞米松0.2 mg/100 g鼠重,對(duì)照組(n=24)注射等量生理鹽水,兩組分別于4 h和12 h各處死8只鼠測(cè)血清腫瘤壞死因子α(TNFα)、淀粉酶,并行胰腺壞死程度評(píng)分、檢測(cè)胰腺腺胞細(xì)胞凋亡,余下8只鼠作生存期觀察。
結(jié)果  治療組4 h、12 h TNFα分別為(17.8±2.7) pg/ml和(8.5±1.6) pg/ml,胰腺腺胞細(xì)胞凋亡指數(shù)分別為(36.94±4.12)%和(32.79±3.31)%,生存時(shí)間為(33.4±21.5) h; 對(duì)照組上述各項(xiàng)指標(biāo)依次為(53.6±18.7) pg/ml和(37.2±11.1) pg/ml (P<0.01)、(4.37±1.24)%和(5.12±2.11)%(P<0.01)及(14.6±5.7) h (P<0.01),兩組胰腺壞死程度評(píng)分差異有顯著性意義(P<0.01)。
結(jié)論  地塞米松能通過(guò)抑制TNFα調(diào)控細(xì)胞凋亡,細(xì)胞凋亡對(duì)胰腺具有保護(hù)作用。
