2012a) was to determine whether or not the marked decreases in dry forage intake after 40 min of feeding are mainly caused by the two factors, that is, ruminal distension and increased plasma osmolality
induced thirst produced by dry forage feeding.
A high plasma osmolality
was associated with a marked increase in mortality in long-term-care patients .
The reason for the increase in blood pressure is a marked increase in circulating plasma volume caused by an increase in plasma osmolality
due to the retention of excessive salt in the blood as the animals' urinary sodium excretion capacity was exceeded between 20 and 29 weeks of age.
Table 3: Tank water osmolality (mmol/kg), mean plasma osmolality
(mmol/kg) and standard error of mean (SE) of blood osmolality of rabbitfish Siganus rivulatus (n = 15) at the end of a 10 week growing period in 15 ppt control sea water (CSW), Trt40 and Trt100.
Because sodium and its associated anions account for about 94 percent of the solute in the extracellular compartment, plasma osmolality
can be roughly approximated as:
, osmolarity, fluid therapy, psittacine, avian, African grey parrot, Psittacus erithacus erithacus, Hispaniolan Amazon parrot, Amazona ventralis, red-fronted macaw, Ara rubrogenys
An acute increase in plasma osmolality
and acidosis may facilitate this movement of potassium (Hirota et al.
Following centrifugation, plasma osmolality
was measured (uOsmette Model 5004, Precision Systems, Natick, MA) to ensure subjects were euhydrated according to ACSM standards (18).
Second, the intensity-dependent increase in AVP during exercise has previously-been attributed to changes in plasma osmolality
occurring at higher exercise intensities due to hypotonic fluid movement from the intravascular to the extravascular space following metabolite accumulation in the muscle tissues (5).
Hyponatraemia reflects relative excess of free water to solute and is usually accompanied by a decrease in plasma osmolality
The ranking of causes/mechanisms associated with IDH were the rate of ultrafiltration exceeds cardiovascular compensation (1st), cardiac dysfunction (2nd), and a decline in plasma osmolality
and extracellular fluid volume (3rd) (see Table 2).
In contrast, when plasma osmolality
is reduced to below 280 mOsm/kg, ADH release is inhibited, no water reabsorption by the kidney occurs, and a large volume of dilute urine is excreted (Tang & Lau, 1995).
