Serum electrolytes ([Na.sup.+], [K.sup.+], [Cl.sup.-]), albumin, and osmolality measurements were conducted immediately on the same day, and the remaining serum samples were maintained at -80[degrees]C until the other biochemical analysis.
Osmolality is a measure of the quantity of osmotically active particles in a solution, expressed as the number of milliosmoles of solute per kilogram of solvent (mOsm/kg) [16].
After 8, 24, 72, and 120 hours after inoculation (hpi), urine was collected to measure the pH and osmolality, and the mice were then euthanized and the bladders and kidneys were removed.
Management of hypernatremia in DKA constitutes of infusing 0.9% normal (isotonic) saline, at a rate of 15-20 milliliters per kilogram per hour or 1-1.5 liters during the first hour, to maintain effective plasma osmolality, in addition to supplementation of potassium [1, 7, 8].
Notably, patient's serum osmolality was 234 mosm/kg (normal range: 275-295 mosm/kg), urine osmolality was 468 mosm/kg, serum sodium was 105 mEq/L (normal range: 135-145 mEq/L), and urinary sodium was 68 mEq/L (normal range 25-150 mEq/L).
The random arginine vasopressin (AVP) level was 1.4pg/mL (normal range 1-13.3 pg/mL) with a random urine osmolality of 285mOsm/kg.
His serum osmolality was 248 mOsm/kg, urine osmolality 387mOsm/kg, and urine sodium 86 mmol/L.
However, PDMS is so porous that the osmolality of culture media is increased by absorption of water into the PDMS [8], making it difficult to use the PDMS for culture of cells and embryos.
Concentrations of sodium, glucose, creatinine, urea, uric acid, and osmolality were measured at different timepoints in serum and urine.
