本研究的目的是评估新生儿感染性休克模型中抗肿瘤坏死因子 α (TNFα) 抗体对 TNFα 基因表达的影响。将10日龄的Sprague-Dawley大鼠分为四组并进行如下腹腔内(ip)注射:第1组:0.1ml盐水;第1组:0.1ml盐水;第2组:0.1 mg/kg肠炎沙门氏菌脂多糖(LPS);第3组:1mg/kg抗TNFα抗体(Ab);第4组:0.1mg/kg LPS和1mg/kg Ab。我们发现,在第 2 组中,LPS 引起休克,表现出低血糖和乳酸血症 (p < 0.05) 以及死亡 (81.8%)。与第 2 组相比,Ab 显着降低了死亡率 (35%),并减轻了第 4 组 8 小时时的低血糖(第 2 组为 35 ± 8 mg/dl,第 4 组为 53 ± 3 mg/dl)和乳酸血症(5.40 ± 0.63 vs. 2.35 ± 0.45 mmol)。Northern 印迹显示,与第 4 组相比,第 4 组中 TNFα mRNA 表达显着降低注射 LPS 后 2 小时至第 2 组。我们得出结论,抗 TNFα 抗体对 LPS 诱导的休克的有益作用可能是由于 TNFα 基因表达降低。
The aim of this study was to evaluate the effect of anti-tumor necrosis factor α (TNFα) antibodies on the TNFα gene expression in a neonatal septic shock model. Ten-day-old Sprague-Dawley rats were divided into four groups and given intraperitoneal (ip) injection as follows: group 1: 0.1 ml saline; group 2: 0.1 mg/kg Salmonella enteritidis lipopolysaccharide (LPS); group 3: 1 mg/kg of anti-TNFα antibodies (Ab); group 4: 0.1 mg/kg of LPS and 1 mg/kg of Ab. We found that in group 2, LPS induced shock, demonstrating hypoglycemia and lactacidemia (p < 0.05) and death (81.8%). Ab decreased the mortality significantly (35%) and attenuated the hypoglycemia (35 ± 8 mg/dl in group 2 vs. 53 ± 3 mg/dl in group 4) and lactacidemia (5.40 ± 0.63 vs. 2.35 ± 0.45 mmol) at 8 h in group 4 when compared to group 2. Northern blot demonstrated a significant decrease in TNFα mRNA expression in group 4 as compared to group 2, at 2 h after LPS injection. We conclude that the beneficial effects of anti-TNFα antibodies on LPS-induced shock may be due to decreased TNFα gene expression.
