The effect of OsO4 at two different osmolar concentrations on mouse mammary carcinoma

Journal of Ultrastructure Research, 1960
Electron 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

Plasma osmolality, iodine concentration and urographic images following high and low osmolar contrast media

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.

[Creatinine concentration, osmolar concentration and blank color as basis for concentration dependent values in urine (author's transl)].

Monatsschrift fur Kinderheilkunde, 1977
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.

changes in ion, urea concentrations and blood plasma osmolarity of Pelobates syriacus juveniles under varying conditions

Comparative Biochemistry and Physiology Part A: Physiology, 1983
Abstract 1. 1. Blood plasma osmolarity and ion concentration, and intra-cellular fluids (muscle) were determined in juvenile toadlets in tap water, in wet soil and after dehydration of 18% body weight or following acclimatization to 400 mM/1 urea. 2. 2.

Hypo-osmolarity stimulates and high sodium concentration inhibits thyrotropin-releasing hormone secretion from rat hypothalamus

Neuroscience, 1999
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 influence of salinity on ionic concentrations and osmolarity of blood serum in lake sturgeon, Acipenser fulvescens

Environmental Biology of Fishes, 1998
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.

[Effect of osmolar concentration of culture media on exocytosis in isolated presynaptic nerve endings of rat brain ].

Biofizika, 2004
The effect of hypotonic and hypertonic shock on exocytosis in rat brain synaptosomes was studied using the fluorescent dye acridine orange. It was shown that an increase in medium osmolarity leads to calcium-independent exocytosis. The response of the probe was directly proportional to the amount of osmolithes added.

Coronary stent evaluation with coronary computed tomographic angiography: Comparison between low-osmolar, high-iodine concentration iomeprol-400 and iso-osmolar, lower-iodine concentration iodixanol-320

Journal of Cardiovascular Computed Tomography, 2014
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 ...
