Phenytoin (DPH) and primidone (PD) are two widely used antiepileptics. The clinical therapeutic effects are known to be related to their serum/plasma concentrations. A modified flash methylative gas-liquid chromatographic method for the determination of serum concentration was presented.In this study, a domestic ohromatography Model "100" equipped with a FID was used. In order to carry out the flash methylation, a new injection port was designed. DPH, PD and M-DPH (IS) were separated from each other on the 3%...

Phenytoin (DPH) and primidone (PD) are two widely used antiepileptics. The clinical therapeutic effects are known to be related to their serum/plasma concentrations. A modified flash methylative gas-liquid chromatographic method for the determination of serum concentration was presented.In this study, a domestic ohromatography Model "100" equipped with a FID was used. In order to carry out the flash methylation, a new injection port was designed. DPH, PD and M-DPH (IS) were separated from each other on the 3% OV-17 stationary phase. The minimal detectable serum concentration of DPH and of PD was 1μg/ml and 2μg/ml respectively. The peak area ratio of drug and IS was linear with concentration in serum over a range of 2~50μg/ml(DPH, r=0.9973) and 4~ 40μg/ml(PD, r = 0.9975). The recovery of DPH in serum was 99.95-105.4%. and PD, 98.90~103.9%. The CV(%) of DPH was not more than 1.71% within twenty-four hours and the CV(%) of PD was less than 6.49%. The day-to-day precision of DPH performed on five successive days was 2.38%(x= 10μg/ml) and 1.81%(x= 15μg/ml). The values of DPH determined by this method were compared with those obtained spectrophotometrically, the correlation coefficient was r=0.9824, Y (UV) = 0.02694+0.9074X (GLC).Thirty-seven DPH serum samples and 7 saliva samples from outpatients were estimated by this method. The average percentage for the samples of binding of DPH to plasma protein was determined to be 91.03±3.06% (M±SD).

本文报道用瞬时甲基化气相色谱法,在改装的国产100型气相色谱仪上,分离和测定体液中同时存在的苯妥英(DPH)和扑痫酮(PD)或其中的一种药物。在血样中应用本法的最低检测浓度DPH为1μg/ml;PD为2μg/ml。用甲基苯妥英(M-DPH)作内标,DPH的线性范围为2~50μg/ml,r=0.9973,方法回收率为99.95~105.4%,天内精密度CV(%)<1.71%,天间精密度CV(%)<2.33%;PD的线性范围为4~40μg/ml,r=0.9975,方法回收率为98.90~103.9%,CV(%)<6.49%。用本法测定DPH的血药浓度和分光光度法比较,r=0.9824,测定值y(uv)=0.02964+0.9074x(GLC)。用本法监测37例DPH的血清样品,多数样品的血药浓度低于10μg/ml,测定值和临床反应基本一致。用本法也能测定药物的唾液浓度,从而计算病人的DPH血浆蛋白结合率,测定7例的结果为91.03±3.06%,与文献报道的89~93%相一致。

本文将利多卡因、布比卡因、普鲁卡因和丁卡因四种局麻药分为酰胺类和酯类二个组,同类药物互为内标,用气相色谱法进行了血药浓度的测定。利多卡因、布比卡因、普鲁卡因和丁卡因的平均回收率和标准差分别为103.79±9.73%、90.18±6.90%、92.52±6.70%、101.04±8.00%,检测限度均小于0.5μg/ml。

The toxicokinetics of sulfur mustard (SM) in vivo and in blood, skin homogenate of human and piglet in vitro were studied. SM was measured by a sensitive and specific gas chromatographic technique with a flame photometric detector.The elimination of SM from normal saline, plasma, erythrocyte suspension of piglet and whole blood, 2 % skin homogenates of human and piglet in vitro were characterized by first-order kinetics.

The toxicokinetics of sulfur mustard (SM) in vivo and in blood, skin homogenate of human and piglet in vitro were studied. SM was measured by a sensitive and specific gas chromatographic technique with a flame photometric detector.The elimination of SM from normal saline, plasma, erythrocyte suspension of piglet and whole blood, 2 % skin homogenates of human and piglet in vitro were characterized by first-order kinetics. The t(1/2) of SM in normal saline was 4.80 min, and in other biosamples were 4-7 min.The time course of SM concentration in blood of piglet following iv SM 10 mg/kg fitted the three-compartment open model. Following a subcutaneous injection of SM, thetoxicokinetics of SM in piglet appeared to fit a first-order absorption one-compartmen open model. No SM had been detected in blood when SM was given percutaneously.The toxicokinetic characteristics of SM in piglet were as follows: 1 . SM could be absorbed rapidly after subcutaneous injection. The half-life of absorption (t(1/2)ka) was 7.45 min; 2 . The rate of distribution of SM was very quick. 90 % SM had been lost from systemic circulation within 2.5 min following a 10 mg/kg intravenous injection. The time required to reach distribution equilibrium between compartments was less than 7 min; 3. There was a combinative store of SM in piglet. During the postdistributive phase, the fraction of SM in the central compartment was only 7 % of total SM in the whole body. The Vbwas 2.47 1 /kg which was 3 times higher than total volume of body water; 4 . The elimination of SM in piglet was rapidwith a half-life of 12.0 min.

用火焰光度检测器气相色谱法分离测定生物样品中的硫芥(SM),研究了SM在离体人血、皮肤匀浆中和小猪体内、外的毒物动力学。SM在37℃生理盐水、人和猪的全血、2%皮肤匀浆、猪RBC混悬液和血浆中均以一级过程被消除。SM在生理盐水中的t_(1/2)为4.80min,在其它生物样品中为4-7min,小猪iv SM符合三室开放模型,sc SM呈一级吸收一室模型,pc SM200mg/kg,4h内均未从血中检出SM。SM在小猪体内的毒物动力学特征是:经皮下吸收快,t_(1/2)ka为7.45min;分布快,不到7min室间分布已达到动态平衡,分布广,V_b是机体含水总量的4倍,提示有结合库;消除快,t_(1/2)β为12.0min;SMiv 10mg/kg后2.5min 90%的SM已从循环血中消失。鉴于SM的毒物动力学特征,SM中毒实际情况相抗毒剂硫代硫酸钠又不能透入细胞内,因此,要抢在SM分布、结合之前给药,显然十分困难。
