ABSTRACT
Objective To master the serum nickel change rule of acute nickel carbonyl poisoning in rats,and to provide laboratory support for clinical treatment of acute nickel carbonyl poisoning patients.Methods SPF rats were given nickel carbonyl (250mg/m3,500mg/m3) in static inhalation for 30min.Rats were anesthetized by ether for 15 seconds after exposure for 30min,2h,4h,8h,12h,24h,48h,72h and 7d respectively.Anatomized rats,kept blood collection 2-3mL,and separated serum 0.5-1mL.Serum nickel was detected by AA800 (American PE company).Results The average serum nickel levels of 250mg/m3 dose group at 30min,2h,4h,8h,12h,24h,48h,72h,7d were (33.69 ±2.59),(24.61 ±3.03),(27.83 ±5.69),(21.36 ±4.14),(20.39 ±4.14),(18.80 ±7.02),(14.51 ±8.21),(13.58 ± 5.78) and (12.83 ± 4.41)μg/L.30 minutes reached the peak,and was 5.30-fold of those in normal controls.There had significant differences compared with normal control(t =5.959,5.958,5.990,5.998,5.997,5.994,5.990,4.317,4.347,all P < 0.01).The average serum nickel levels of 500mg/m3 dose group at 30min,2h,4h,8h,12h,24h,48h,72h,7d were (72.22 ± 1.62),(57.78 ± 12.99),(42.25 ± 7.25),(103.77 ± 11.11),(79.04 ±12.26),(26.35 ±6.56),(18.58 ±4.92),(17.22 ±9.73),(14.59 ±5.27) μg/L.8h reached the peak,and was 16.33-fold of normal controls.The differences were significant (t =5.960,5.947,5.978,5.927,5.948,5.959,3.143,2.447,2.440,all P < 0.05).Meanwhile,there were significant differences between two groups of 30min,2h,4h,8h,12h(t =5.208,2.447,2.449,5.959,5.959,P =0.001,0.049,0.042,0.000,0.000),but there was no significant difference after 24h.Conclusion There was significant doses-effect relationship between serum nickel content of acute nickel carbonyl poisoning rats and the dosage.Nickel carbonyl or its metabolites were excreted mainly within 24h.
