Abstract:
Objective To observe the changes of serum S100B and MBP in rats with liquid petroleum gas poisoning. Methods Fifty-four healthy adult male SD rats were randomized into normal control group (n=6), 20% LPG poisoning group (n=24) and 50% LPG poisoning group (n=24). Rat models of liquid petroleum gas poisoning were established in the later 2 groups, and controls were given the same volume of air. The rats of each group(n=6) were scored with neurological severity scale (NSS) and the blood serum was collected on the 1st, 2nd, 3nd and 7th d of poisoning, respectively. The levels of S100B and MBP were detected by euzymelinked immunosorbent assay (ELISA).Results As compared with the scores of NSS in the normal control group, those on the 1st d of poisoning in the 20% LPG poisoning group and those on the 1st and 2nd d of poisoning in the 50% LPG poisoning group were significantly higher (P＜0.05). The levels of Sl00B and MBP in 20% and 50% LPG poisoning groups were higher than those in the control group on the 1st and 2nd d of poisoning (P＜0.05); the levels of S100B and MBP in 50% LPG poisoning group were higher than those in 20% LPG poisoning group on the 1st and 2nd d of poisoning (P＜0.05). The levels of S 100B and MBP in 50% LPG poisoning group were higher than those in 20% LPG poisoning group and normal control group on the 3rd of poisoning (P＜0.05). The NSS scores and the levels of S100B and MBP in rats with LPG poisoning enjoyed the highest scores or levels on the 1st d of poisoning and those decreased after that. Conclusion The levels of S100B and MBP of rats with LPG poisoning increase, indicating that gliocytes participate in the mechanism of nervous system injury in rats with liquid petroleum gas poisoning.
