Effect of pregnancy on gravid sclerosis of bovine uterine arteries.
Gravid sclerosis of the uterine artery was histologically examined in multiparous cows. This sclerosis was characterized by a thickening of the intima and a lamination of the internal elastic lamina. It was clearly observed at non-pregnant and early-pregnant stages and in the late postpartum period, but it could not be detected at term-pregnant stages and in the early postpartum period. These results suggest that the gravid sclerosis disappears during pregnancy and re-establishes after parturition. The importance of local factors, e.g. hemodynamics, in the cyclic appearance of gravid sclerosis is discussed.
