To establish whether the use of proteinase inhibitors in the routine determination of in vitro plasma renin activity overestimates the potency of renin inhibitors in vivo, we examined the effects of phenylmethylsulfonyl fluoride and 8-hydroxyquinoline sulfate on the binding to plasma proteins and the respective IC50 values (50% inhibiting concentrations) of three renin inhibitors. All three ren...

The fluorine content of drinking waters has become a matter of great interest to those concerned with the control and diminution of dental caries. In the U.S.A. many are of the opinion that the epidemiological studies of Dean (1938) and his co-workers (Dean, Arnold & Elvove, 1942) provide convincing evidence for the belief that, within certain limits, there is an inverse relationship between th...

BACKGROUND Fluoride additives contain metal contaminants that must be diluted to meet drinking water regulations. However, each raw additive batch supplied to water facilities does not come labeled with concentrations per contaminant. This omission distorts exposure profiles and the risks associated with accidents and routine use. OBJECTIVES This study provides an independent determination of...
