title: [Dynamics of renal medullary vinculin under changing of osmoregulating function].
abstract: Reduction of vinculin occurs in the renal medulla under the long-lasting dehydration. The protein content measured in inner medulla of rats of the WAG line under hydration was 92.1 +/- 6.3 in relative units, but it was only 77.6 +/- 2.3 after a 3-day water deprivation. The vinculin content in the inner medullar layer from mutant rats of Brattleboro line incapable of synthesizing vasopressin is essentially higher: it is 188.9 +/- 8.5 in hydrated conditions and drops to 148.4 +/- 7.3 under a 3-day dehydration. The same high level of vinculin is in outer medulla from rats of Brattleboro line: 222.1 +/- 11.8 in hydrated animals and 174.9 +/- 11 after a 3-day dehydration. No differences were revealed in response of vinculin to alternative osmoregulating stimulation in cortex in both rat lines.
