Emergency screening of urine, plasma, or gastric contents for barbiturates.
THERE IS AN EVER-increasing need for a rapid method of screening for barbiturates in the laboratory. Although the ultraviolet methods (1, ) are the most accurate, they require 0.5 to 2 h of technician time and therefore are hardly ideal for emergency-room use. Some methods have been published which depend on the complexing reaction of barbiturates in an organic solvent with a mercury salt in an...
متن کاملSimultaneous detection of morphine and barbiturates in urine by radioimmunoassay.
This report describes a radioimmunoassay for the simultaneous detection of morphine and barbiturates. Morphine and barbiturate antibodies, obtained from goats, were mixed with 125l-labeled antigens. By adjusting concentrations of the morphine and barbiturate antibodies and radiolabeled antigens, closely superimposed standard curves for the two drugs would be obtained. As a consequence, similar ...

A Simple and Rapid Method for the Detection of HIV-1/HCV in Co-Infected Patients
Background: Due to some limitations of serological methods in diagnosis of patients infected with HIV-1 (human immunodeficiency virus) and HCV (hepatitis C virus), it is profoundly important to use molecular methods for the detecting of these infectious agents. However, the most significant problems are the exorbitant cost of these methods and the need of a thermocycler which is an expensive...
متن کاملA Simple, Rapid Method for Paper Chromatography of Barbiturates.
Barbiturates are extracted quantitatively into ethyl ether from biologic fluids buffered to pH 6. A measured portion of the ether extract is then impinged to dryness and the residue spotted on Whatman No. 2 paper that has been previously dipped in alkali and dried. The paper is developed by descending chromatography with chloroform saturated with water. The barbiturate may then be located and a...
