Action of vasopressin on the permeability of mesentery.
Contemporaneous movements of Rb86 cations and of P(32) orthophosphate across isolated rabbit mesentery display kinetic patterns that are generally associated with passive diffusion. Vasopressin at a concentration of 100 milliunit/ml produced a significant increase in the permeability constant for P(32) and at the same time a significant decrease in the permeability to Rb(86). At lower hormone concentrations (0.1 milliunit/ml) the P32 response was less marked but still significant (P < .01), while the Rb(86) effect was not (P > .05). Hyaluronidase did not mimic these actions of vasopressin.
