serum fatty acids on 30 healthy lranian women were detemined by a gas chromatographic method. oleic and stearic acids were used as standards. the mean values were myristic acid 5. 7% , palmitic acid 43% , palmitoleic acid 5.3% , stearic acid 8% , oleic acid 21. 3% and linleic acid 16.4% of total fatty acid serum contents.

A gas-chromatographic method for the diagnosis of urinary tract infections caused by Escherichia coli and Klebsiella sp. is described. A total of 96 urine samples from individuals with clinical symptoms of urinary tract infection or pyrexia of unknown origin were tested by conventional and gas-chromatographic methods for bacteriuria. The gas-chromatographic method showed complete agreement with...

a simple, reproducible and rapid gas chromatographic method for precise determination of valproic acid (vpa) in human plasma has been developed. total time for sample preparation and gc analysis is less than 45 min. after plasma protein precipitation, vpa was extracted into chloroform with suitable recovery. by using stabilwax®-da capillary gc column, a symmetrical gas chromatographic peak was ...

A simple and specific method is presented for the capillary gas chromatographic determination of trazodone in postmortem blood and tissues. The drug and trimethobenzamide, which was used as an internal standard, were extracted with 1% isopropanol in n-butyl chloride. Chromatography was accomplished with a short (4-m) methyl silicone capillary column and hydrogen carrier gas. This combination of...

I describe a rapid, simple routine gas-liquid chromatographic method for simultaneous isothermal quantitation of disopyramide and its mono-N-dealkylated metabolite. The method involves one extraction step with dichloromethane, derivatization of the metabolite, and gas chromatography with an OV-17 liquid phase. Standard curves were linear over the concentration range tested (0.1-25 mg/L) and the...

A gas chromatographic procedure for the simultaneous determination of carbamazepine, phenobarbital and phenytoin using SP 2510 DA as stationary phase is presented. The antiepileptic drugs are determined simultaneously without derivatisation under isothermal conditions by a flame ionisation detector. The gas chromatographic procedure can be easily mechanized. The coefficient of variation for the...

A liquid-chromatographic assay of 5-fluorouracil in plasma is described. Advantages of this procedure over gas chromatography are the simpler extraction procedure, elimination of the need for a derivitization step with silylating agents, and a 20-fold greater sensitivity. The minimum detectable concentration of 5-fluorouracil in plasma is 25 microgram/L. The enhanced sensitivity enabled measure...

benign prostatic hyperplasia generally affects males above fourty years of age and has significant effect in overall quality of life (qol). this is one of the cause of millions of dollors in healthcare expenditure. alpha one adrenoreceptor blockers are frequently used for the benign prostatic enlargement because of their significant effect on storage and voiding symptoms, qol, flow rate and pos...
