Abstract:
Vulvar tissue hydration of oestrous and dioestrous lactating cows was studied by determining cell density (CD), dry matter (DM), total tissue water (TTW), extracellular water (ECW), and Na+ and Cl- concentrations in tissue biopsies. Na+, Cl- and osmotic concentrations (OC) in blood plasma were also determined. Each cow was biopsied during oestrus (Oe) and 10-13 days later (dioestrus, Di). CD (n = 4 cows) was determined in quick-frozen microscopic preparations. ECW (n = 9 cows) was determined by the 3H-inulin space method. During Di and Oe, the mean CDs were 43 and 25 cells/ng of mesenchymal tissue, respectively; the mean DM + TTW/cell (n = 17 cows) was approximately 74% greater in Oe than in Di. During Di, the mean DM, ECW and calculated intracellular water (ICW) were 24.2, 19.8 and 56.0 g/100 g tissue, respectively. During Oe, there was an absolute mean weight increase of 18.4, 38.0 and 17.6 g/100 g tissue in Di, in the DM, ECW and ICW, respectively. However, on a percentage basis, DM did not differ (24.5 vs 24.2%), ECW increased (33.2 vs 19.8%) and ICW decreased (42.4 vs 56.0%) during Oe vs Di, respectively. Plasma Na+, Cl- and OC were lower (P < 0.05) during Oe than during Di (Na+ = 123.1 ± 2.6 vs 130.9 ± 1.5 mEq/l plasma; Cl- = 89.3 ± 3.1 vs 97.0 ± 1.4 mEq/l plasma; OC = 281 ± 4.8 vs 300.2 ± 1.8 mOsm/kg plasma, respectively). In contrast, tissue Na+ and Cl- (mEq/100 g tissue) during Oe and Di did not differ (Na+ = 7.8 ± 0.8 vs 7.7 ± 0.9; Cl- = 7.6 ± 0.5 vs 7.8 ± 0.5, respectively). © 1990.
