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 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

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 ...

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.

Clinical Radiology, 1991
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.

This study examined the extent to which lake sturgeon, Acipenser fulvescens, regulated serum ion concentrations and osmolarity in relation to ambient salinity. Twenty juvenile lake sturgeon, brood stock from the Moose River in the Hudson Bay drainage basin, were gradually transferred from freshwater to more saline waters at a rate of 2‰ day-1.

American Journal of Obstetrics and Gynecology, 1984
Human uterine fluid and serum, when analyzed, had the same osmolarity. Both the total cation concentration and that of albumin were lower in uterine fluid than in serum. Decreased cation concentration is probably a regulatory mechanism maintaining electroneutrality in uterine fluid when the protein concentration is decreased, since protein molecules ...

Journal of Experimental Zoology, 1965
AbstractSeveral thousand two‐cell mouse ova were cultivated in vitro, and the effect on development of changing the osmolarity and hydrogen ion concentration of the medium was examined. Statistical experimental design techniques were employed throughout the experiments in order to make the most efficient use of the material available.

Abstract 1. 1. Hemolymph osmolarity increases more (165–208 mOsM) when the animal is rapidly dehydrated than when more slowly dehydrated (165–182 mOsM). 2. 2. Hemolymph Na + and Cl − concentrations increase with rapid dehydration but not with slow dehydration. 3. 3. Rehydration of rapidly dehydrated animals results in osmolarity and Na +
