We compared the effects of early and late stage hypothermia treatment after spinal cord injury. Five groups each consisting of seven rats were included in this study. In Group 1a (Clip applied-non-treatment group) and Group 1b (Clip applied-treated group) the spinal cords were harvested 1 h after the injury. In Group 2a (clip applied, non-treated group) and Group 2b (clip applied-treated group) the injured segments were harvested 24 h after injury. Group 3 was designed as the sham-operated group. The significantly lower levels of TBARS and GSH-Px in Group 2a, as compared with Group 1b suggests that the hypothermia was effective in the early stage of treatment (P < 0.05). In contrast, TBARS and GSH-Px levels were significantly increased at the 24 h timepoint following treatment (P < 0.05). Short-term systemic hypothermia reduces lipid peroxidation in the early stages after spinal cord injury. This beneficial effect disappears 24 h following systemic hypothermic treatment.
我们比较了脊髓损伤后早期和晚期低温治疗的效果。本研究纳入了五组,每组七只大鼠。在1a组(夹闭-未治疗组)和1b组(夹闭-治疗组)中,损伤后1小时采集脊髓。在2a组(夹闭-未治疗组)和2b组(夹闭-治疗组)中,损伤后24小时采集损伤节段。第3组设计为假手术组。与1b组相比,2a组中TBARS和GSH-Px水平显著降低,这表明低温在治疗早期有效(P < 0.05)。相反,治疗后24小时时,TBARS和GSH-Px水平显著升高(P < 0.05)。短期全身低温可降低脊髓损伤后早期的脂质过氧化。全身低温治疗24小时后,这种有益效果消失。
