Determination of n-acetyl-p-aminophenol in plasma.
Two methods for the determination of N-acetyl-p-aminophenol (APAP) in plasma that differ in principle from the diazotization procedure of Brodie and Axelrod (1) are described. One method based on the differential absorption peak of APAP at 266 m, which corresponds to the isosbestic point of common drugs such as acetylsalicylic and salicylic acids, is simple and most specific for APAP. The other...
متن کاملEffect of Paracetamol (n-acetyl-p-aminophenol) on Gastrointestinal Bleeding.
There is now ample evidence that the oral administration of aspirin leads to an increase in faecal blood loss in the majority of normal people. Some investigators (Lange, 1957; Alvarez and Summerskill 1958; Stubbe, Pietersen, and Van Heulen, 1962) have used chemical means of testing for occult blood in faeces, and others (Matsumoto and Grossman, 1959; Watson and Pierson, 1960; Holt, 1960; Scott...
متن کاملGas-chromatographic method for acetaminophen (N-acetyl-p-aminophenol) based on sequential alkylation.
A gas-chromatographic procedure for acetaminophen is described in which the drug is chromatographed as the O-heptyl-N-methyl derivative. This derivative is prepared by a sequential alkylation procedure in which the phenolic hydroxyl group of the parent compound is alkylated off-column with heptyl iodide and the amide group is derivatized on-column by reaction with trimethylanilinium hydroxide. ...
متن کاملFabrication of Graphene–LaMnO3 Sensor for Simultaneous Electrochemical Determination of Dopamine and Uric Acid
Dopamine (DA) and uric acid (UA) are two of important bimolecular widely circulated in body blood. Therefore, development of simple and rapid methods for simultaneous determination of them in routine analysis has a great significance for many researchers. Therefore, for the first time, nanocomposite of graphene (Gr)LaMnO3has been utilized to fabricate the new ...
متن کاملGraphene-nanoplatelet-based photomechanical actuators.
This paper reports large light-induced reversible and elastic responses of graphene nanoplatelet (GNP) polymer composites. Homogeneous mixtures of GNP/polydimethylsiloxane (PDMS) composites (0.1-5 wt%) were prepared and their infrared (IR) mechanical responses studied with increasing pre-strains. Using IR illumination, a photomechanically induced change in stress of four orders of magnitude as ...
