Metronidazole and tetracycline E tests were compared to an agar dilution method for the antimicrobial susceptibility testing of Helicobacter pylori. Sixteen strains were tested by using tetrazolium egg yolk (TEY) agar. The characteristic E test inhibition ellipse was clearer on TEY agar than on standard blood agar and gave results comparable to those of the agar dilution test. The use of TEY me...

By ALDEN ROSS ADAMS, M.Sc. AND WILLIAM A. MOSHER, PH.D. T HE CONCENTRATION DISCREPANCIES between serum and! plasma from the same sample of blood raise the dluestiOns: (1) To what extent does a given anticoagulant cause dilution of the plasma? (2) If the dilution’ varies with the anticoagulant, what is the basis for the difference? Serum samples’4 were found to be more concentrated in their comp...

the study of the role of money in the economy of developing countries, and its impact on economic variables, analysis of monetary policies, and other related issues are of paramount importance in economic planning. considering the above-mentioned points and also the realities of iranian economy, it is quite vital to scientifically specify the long-term trend of money supply through investigatio...

background: leishmaniases are a group of diseases caused by leishmania parasites .  growing of drug unresponsiveness in leishmaniasis patients necessitates the development of new drugs and accor­dingly a suitable assay is needed for evaluation of any modalities.  the aim of this study was to compare four drug assays methods, agar dilution, broth dilution, cylinder plate and disk diffusion, for ...

the objective of this study is to estimate the demand for money in iran using the autoregressive distributed lag (ardl) approach to cointegration analysis. the empirical results show that there is a unique cointegrated and stable long-run relationship among m1 monetary aggregate, income, inflation and exchange rate. we find that the income elasticity and exchange rate coefficients are positive ...

Cardiac output is often measured by indicator dilution techniques, usually based on dye or cold saline injections. Developments of more stable ultrasound contrast agents (UCA) are leading to new noninvasive indicator dilution methods. However, several problems concerning the interpretation of dilution curves as detected by ultrasound transducers have arisen. This paper presents a method for blo...

Fatal acute haemolysis occurred in a 65-year-old man undergoing regular home haemodialysis for terminal renal failure. Circumstantial evidence indicating that the haemolysis resulted from exposure to concentrated dialysis solution was supported by in-vitro studies. Frank haemolysis in blood samples occurred at a dilution of greater than or equal to 1/2 of dialysis fluid. Osmotic fragility tests...
