Abstract

Analyses of uterine sodium, potassium, chloride, wet weight and dry weight were accomplished on estrogen-treated ovariectomized rats that were sacrificed at discrete hourly intervals following hormone injection. Peak increments were found at 4 hours for all responses measured except potassium. The increase in sodium as compared to chloride was far greater than could be accounted for on the basis of accumulated plasma ultrafiltrate or on the basis of leakage of plasma protein.
