Changes in plasma osmolality in food poisoning

Osmolality changes in nebulizer solutions.

Paradoxical effects (bronchoconstriction instead of bronchodilatation) have been reported after inhalation of beta2-mimetics in asthmatic children, and it has been suggested that this was due to osmolality and pH changes of the nebulizer solution. We tested commercially available nebulizer solutions and found osmolality changes after 5, 10 and 15 min of nebulization. Osmolality was measured in ...

Resistance responses to local changes in plasma osmolality in three vascular beds.

GAZITGA, S., J. B. SCOTT, B. SWINDALL, AND F. J. HADDY. Resistance responses to local changes in plasma osmolality in three vascular beds. Am. J. Physiol. 220(Z) : 384-391. 1971 .-The effects of local changes in plasma osmolality (durations of 3-10 min) on resistance to blood flow were compared in the forelimb, renal, and coronary circulations of anesthetized dogs. A 40to 50mOsm/kg increase in ...

The sensitivity of the human thirst response to changes in plasma osmolality: a systematic review

Background Dehydration is highly prevalent and is associated with adverse cardiovascular and renal events. Clinical assessment of dehydration lacks sensitivity. Perhaps a patient's thirst can provide an accurate guide to fluid therapy. This systematic review examines the sensitivity of thirst in responding to changes in plasma osmolality in participants of any age with no condition directly eff...

Food Poisoning

In this, the third edition of his well-known work, Dr. Dack has made a thorough revision and incorporated the newer knowledge of a subject which affects each of us at one time or another. The first two chapters on chemical poisoning and poisonings due to substances found in plants, fish, and shellfish contain useful tables of specific agents, incubation periods, symptoms, and foods involved.
