Reliability of coronary angiography by multidetector row CT (MDCT-CA) for stent evaluation is still a matter for debate, and it is unknown whether contrast medium characteristics may affect diagnostic performance of MDCT-CA.We compared iomeprol-400 with iodixanol-320 to evaluate coronary stents with MDCT-CA.We randomly assigned 254 patients undergoing ...

RENAL concentrating ability in response to an antidiuretic stimulus presumably is limited by a maximum urine osmotic pressure or osmotic urine-plasma gradient or ratio. Hence, the determination of urine and plasma osmolality by freezing-point depression in the hydropenic state or after vasopressin administration should make possible the precise ...

Three contrast media (sodium iothalamate, iopamidol and sodium/methylglucamine ioxaglate) in a dose of 240 mg iodine per kilogram of body weight were compared in clinical urography. The ionic monomer sodium iothalamate was the only medium to significantly elevate the plasma osmolality though it returned to normal values within 4 min.

To clarify the question whether solute and water fluxes between pelvic urine and the renal papilla contribute to the medullary accumulation of osmotically active substances and thus to final urine concentration, we measured the osmolarity of urine samples from the papillary tip of rat kidneys during superfusion of the exposed papillae with solutions of

The hypothalamic paraventricular nucleus, representing cell bodies in which thyrotropin-releasing hormone is synthesized, and the median eminence, representing nerve terminals, were incubated in vitro. Various hypo- and hyperosmotic solutions were tested to determine osmotic sensitivity of thyrotropin-releasing hormone secretion.

The effect of OsO4 at two different osmolar concentrations on mouse mammary carcinoma
Journal of Ultrastructure Research, 1960Electron microscopic study of mouse mammary carcinoma fixed in isotonic and hypotonic OsO4 showed that cytoplasmic elements were better preserved with greater retention of cellular material in the isotonic fixative. The nucleoplasmic material, however, was retained better and distributed more evenly in tissue fixed in the hypotonic fixative, suggesting

The correlation between Creatinine concentration, osmolality and blank color of urines was investigated. Only values of creatinine concentration and osmolality allow an approximative inter-conversion. For urine analysis, especially in cases of a very high creatinine concentration, we recommend to measure osmolality as a control.

A COMPARISON OF THE CALCULATED AND DETERMINED OSMOLAR CONCENTRATION OF NORMAL SERUM
American Journal of Diseases of Children, 1929Recent observations made in different laboratories have emphasized the fact that the total electrolyte content of the blood plasma, and presumably of the body fluids in general, tends to be maintained at a relatively constant level in spite of wide variations in the concentrations of individual ions, and in spite of large fluctuations of plasma water ...
