Assay of Nifuratel in Urine
SYNOPSIS The minimum inhibitory concentrations of nifuratel for 205 randomly selected isolates from urinary tract infections were tested by tube dilution. Of these, 177 (86-3 %) were resistant to more than 6 Htg/ml and 140 of 141 (99 3 %) strains of Escherichia coli were resistant to more than 3 ,g/ml. Urine levels of nifuratel were examined in two groups: one group had 400 mg given once and th...
متن کاملCreatinine content of urine and bacterial growth.
SIRy-Mr. W. L. Whitehouse (21 June, p. 759), like myself' and many others, again calls attention to the potential dangers of rhesus isoimmunization in therapeutic abortion. He asks that the extent of this problem be further and scientifically investigated. There are, in fact, one or two further facets to be considered. Firstly, all of us are aware of the numbers of women whose first continuing ...
متن کاملNicotinic acid assay in blood and urine.
ICOTINIC ACID and its derivatives occur in biologic materials as nicotinic acid, as nicotinamide, and in two co-enzymatic forms: diphosphopyridine nucleotide (DPN), and triphosphopyridine nucleotide (TPN). Among mammals, only man and dog are known to develop syrnptoms of nicotinic acid deficiency. In man, deficiency results in dermatitis, diarrhea, delirium, and death. Recently, nicotinic acid ...
متن کاملImproved turbidimetric assay for lysozyme in urine.
I describe an improved turbidimetric assay for lysozyme in urine. This method is simple, reproducible, linear over a 100-fold concentration range, sensitive to concentrations as low as 10 micrograms/L, and only commercially available products are required. Evaluation of urinary lysozyme concentration with this assay demonstrated a within-run and between-run CV of 9.9% and 4.8%, respectively, fo...
متن کاملNovel urine hepcidin assay by mass spectrometry.
The hepatic peptide hormone hepcidin is the central regulator of iron metabolism and mediator of anemia of inflammation. To date, only one specific immuno-dot assay to measure hepcidin in urine had been documented. Here we report an alternative approach for quantification of hepcidin in urine by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS). Peptid...
