摘要: 目的 观察青霉素G、头孢唑林、妥布霉素和克林霉素在兔椎间盘髓核中的分布。方法 兔耳静脉注射4种抗生素,采用高效液相色谱法测定兔血清、正常椎间盘和感染后椎间盘在给药后0.5h和1h时的药物浓度(含量),并比较血清浓度与髓核含量之间的相关性。结果 比较髓核中药物含量与血清中药物浓度的比例,药物进入髓核分布比例青霉素G<头孢唑林<妥布霉素<克林霉素。感染后进入髓核的比例增加,除青霉素G外,其他药物髓核药物含量/血清药物浓度,感染组均大于正常组,并且妥布霉素和克林霉素明显增加(P<0.05)。药物在髓核中消除速度比在血清中慢。结论 血清的药物浓度与髓核含量无相关性;妥布霉素和克林霉素治疗椎间盘感染应为首选。

Abstract: Aim The distribution of four antibiotics:penicillin G,cefazolin,tobramycin and clindamycin in the nucleus of intervertebral discs in New Zealand rabbit was studied.Methods At 0.5 and 1 hour after ear intravenous injection,the concentration of four antibiotics in serum and in nucleus in infected intervertebral discs of rabbits were determined by high performance liquid chromatography methods.The antibiotic concent rations of serum and nucleus w ere compared.Results The ratios of nucleus to serum antibiotic concentration were ranged from low to high in asequence of penicilin G,cefazolin,tobramycin and clindamycin.The ratioes for the antibiotics,except for penicillin G,were increased in infected rabbit,with the ratios for tobramycin and clindamycin increased markedly (P<0.05).The rate of removing on the antibiotics from nucleus was lower than from serum.Conclusion There is no interrelation of cerum and nucleus in antibiotic concentrations.Clindamycin and tobramycin are the antibiotics of shoice in treating infected intervertebraldiscs.
