Presence of urea in rat brain.
This paper reports the presence of urea in rat brain and the evidence that it does not come from blood contamination. The amount of urea is higher during the first 4 days after birth, and it decreases thereon as the brain develops. Urea concentration in brain remains constant from the age of 9 days to 1 year. A possible mechanism of brain urea formation is discussed.
