In a previous communication,we have reported the physiological disposition of N-C~(14)-formylsarcolysine.In as much as the tracer technic does not distinguish the unchanged drug from its metabolite(s),a highly specific method is developed for the determination of N-formylsarcolysine in biological samples. One ml of sample (whole blood,tissue homogenate (1:5),urine (1:1),bile and feces (1:10)) was pipetted into a centrifuge tube containing 20-40 mg of sodium bicarbonate and well shaken until dissolved.To the...

In a previous communication,we have reported the physiological disposition of N-C~(14)-formylsarcolysine.In as much as the tracer technic does not distinguish the unchanged drug from its metabolite(s),a highly specific method is developed for the determination of N-formylsarcolysine in biological samples. One ml of sample (whole blood,tissue homogenate (1:5),urine (1:1),bile and feces (1:10)) was pipetted into a centrifuge tube containing 20-40 mg of sodium bicarbonate and well shaken until dissolved.To the alkaline sample,10 ml of absolute alcohol was added to precipitate protein.The protein-free supernatant was evaporated to dryness under reduced pressure.The residue was dissolved in 5 ml of 0.1 M acetate buffer (pH 3.6) and extracted three times with 5 ml volumes of ethyl acetate.The pooled extract was again evaporated to dryness.The residue was dissolved in 5 ml of absolute alcohol and the light absorptions measured at 240,258 and 280 mμ.Since the absorption curve obtained from biological specimens is the additive effect of the absorption due to the blank specimen (which is essentially a straight line between 240 and 280 mμ,fig.1,Ⅲ) plus the actual N-formylsarcolysine curve,it is evident that the peak absorption at 258 mμ cannot be used as a measurement of drug concentra- tion without subtracting an unknown fraction contributed by the blank specimen.Based on the absorption spectrum of N-formylsarcolysine (fig.1,I),points A,B and C represent the optical densities at 258 (maximum absorption),240 and 280 mμ res- pectively.When a line was drawn from A perpendicular to the abscissa and crosses BC at D,the distance between A and D was found to be proportional to the quantity of N-formylsarcolysine in the sample.Interference by blank materials may thus be elimi- nated.The magnitude of D may also be calculated according to the equation: D=0.55B+0.45C. This method was shown to be very sensitive and highly specific. Five hours after an oral dose of N-formylsarcolysine (200 mg/kg) to normal rats, about 7.9% of the dose could be recovered from the gastrointestinal tract as unchanged drug.Since in vitro experiments showed that N-formylsarcolysine was rapidly meta- bolized to compounds not determined by this method,the disappearance of N-formyl- sarcolysine from the gastrointestinal tract does not reflect the actual absorption of the drug. When injected intravenously to rats and rabbits,N-formylsarcolysine disappeared rapidly from the blood with a biological half life of 12-15 minutes.In normal rats, about 23.8% of the administered dose was excreted in the urine in five hours.During the same period,the urinary excretion by rabbits was about 12.5%.In rats with a biliary cannula,as much as 12.4% of an intravenously injected dose could be reco- vered from the bile in five hours. One hour after N-formylsarcolysine (100 mg/kg) was given intravenously to normal rats or rats bearing Yoshida solid carcinoma,appreciable concentration was found in the kidneys,relatively low concentrations were present in the liver,while only trace amounts were present in the tumour and other tissues examined. When a dose of 300 mg of N-formylsarcolysine was given orally to patients suffer- ing from seminoma of the testis,very low concentrations of unchanged drug were found in the blood.About 7.1% of the administered dose was excreted in the urine. The hydroxy form of N-formylsarcolysine was shown to be the main metabolite in rats as well as in patients.

本文报告用分光光度计,采用三波长法在生物样品(血、尿、组织、胆汁及粪等)中测定N-甲酰溶肉瘤素(简称 N-甲)的方法;并用此法观察了 N-甲在动物及人体内的吸收、分布及排泄。本法特异性高,灵敏度为0.10 O.D.相当于样品中含 N-甲11.5微克。大鼠口服 N-甲200毫克/公斤后5小时,由胃肠道内容物可回收剂量的7.9%,而在所排出的粪中并无可测定的药物存在。体外实验证明 N-甲在胃肠道内容物的代谢很快。可见,药物由胃肠道消失的速度并不能反映其自胃肠道吸收的情况。静脉注射后,N-甲在大鼠及家兔的血中消失很快。其在血中的生物半衰期大鼠为12分钟,家兔为15分钟。给正常或肿瘤大鼠静脉注射 N-甲100毫克/公斤后1小时,药物含量以肾脏最高,肝次之,脾、肺、心等组织仅含痕迹量。肿瘤组织的药物含量亦很低。大鼠静脉注射 N-甲100毫克/公斤后5小时,由尿可回收剂量的23.8%,其中96.3%为前两小时所排出。由胆汁亦可回收剂量的12.4%。家兔静脉注射 N-甲50毫克/公斤后,12小时内可自尿排出剂量的12.5%,其中92.6%为前两小时所排出。成年男性肿瘤患者一次口服 N-甲300毫克后5小时内,血中的药物浓度...

The main cause of too small flanged hole end diameter on parts of the Audi car has been found by analysis to be thinning of blank material and rebound. In order to solve the problem,proless as ironing may be increased for thicker blank and bigger ontside diameter flanged hole. while for thick blank and smaller ontside diameter flanged hole,method of increasing diame ter of punch and reduce clearance between punch and die of the hole may be employed.

对奥迪轿车零件翻孔端部直径偏小的分析结果表明,其主要原因是材料变薄及回弹所致。为解决这一问题,对于材料较厚及外径较大的翻孔,可考虑增加整孔工序;而对料厚及外径较小的翻孔,可以采用增大凸模外径,减小模具间隙的方法来实现。
