QUANTITATIVE DETERMINATION OF RESIDUAL MONOMETHYLAMINE CONTENT IN NEBIVOLOL HYDROCHLORIDE BY HPIC WITH SUPPRESSED CONDUCTIVITY DETECTION.

Acta poloniae pharmaceutica
The aim of this paper was to develop a simple analytical method which could be used to determine a synthesis-derived amount of monomethylamine (MMA) residue present in nebivolol hydrochloride. High-performance ion chromatography (HPIC) method with su...

Potential of Piper betle extracts on inhibition of oral pathogens.

Drug discoveries & therapeutics
In the present study, antimicrobial activity of Piper betle crude ethanol extract against 4 strains of oral pathogens; Candida albicans DMST 8684, C. albicans DMST 5815, Streptococcus gordonii DMST 38731 and Streptococcus mutans DMST 18777 was compar...

[Development of an HPLC-UV Method for Free Asparagine in Grains].

Shokuhin eiseigaku zasshi. Journal of the Food Hygienic Society of Japan
A novel analytical method was developed for the determination of free asparagine (Asn), which is a precursor of acrylamide, in grains. Asn was extracted from a sample with 5% (w/v) aqueous trichloroacetic acid solution, and the crude extract was clea...

The effects of sternal intraosseous and intravenous administration of amiodarone in a hypovolemic swine cardiac arrest model.

American journal of disaster medicine
OBJECTIVE: This study compared the effects of amiodarone via sternal intraosseous (SIO) and intravenous (IV) routes on return of spontaneous circulation (ROSC), time to ROSC, concentration maximum (C), time to maximum concentration (T), and mean conc...

The effects of tibial intraosseous versus intravenous amiodarone administration in a hypovolemic cardiac arrest procine model.

American journal of disaster medicine
OBJECTIVE: This study compared the effects of amiodarone via tibial intraosseous (TIO) and intravenous (IV) routes on return of spontaneous circulation (ROSC), time to ROSC, maximum drug concentration (Cmax), time to maximum concentration (Tmax), and...

The effects of sternal and intravenous vasopressin administration on pharmacokinetics.

American journal of disaster medicine
OBJECTIVE: Purposes of this study were to compare intravenous (IV) and sternal intraosseous (SIO) administration of vasopressin relative to concentration maximum (Cmax), time to maximum concentration (Tmax), and mean concentration in a cardiac arrest...
