Loss of body weight is accompanying cellular brain edema induced by water intoxication in the rat.

Loss of body weight is accompanying cellular brain edema induced by water intoxication in the rat. Physiol Res. 2019 Jan 10; Authors: Kozler P, Marešová D, Pokorný J Abstract Induction of cellular cerebral edema (CE) was achieved by a standard method of water intoxication which consisted of fractionated intraperitoneal administration of distilled water (DW) together with the injection of desmopressin (DP). Using metabolic cage, fluid and food balance was studied in two groups of eight animals: group C - control; group CE - cellular edema induced by water intoxication. For each rat the intake (food pellets and water) and excretion (solid excrements and urine) were recorded for 48 h together with the initial and final body weight. CE animals consumed significantly less food, drank less water and eliminated the smallest amount of excrements. The induction of cellular cerebral edema was accompanied with a significant loss of body weight (representing on average 13 % of the initial values) mainly due to a reduction of food intake. This phenomenon has not yet been reported. PMID: 30628836 [PubMed - as supplied by publisher]
