Comments
It was hypothesized that replacing female sex hormones in ovariectomised rats would enable them to maintain their normal food intake and body weight after hypertonic NaCl loads as opposed to the decrease in both measures typically observed in male and ovariectomised rats. A group of 6 rats received sham operations and sesame oil injections; 4 groups of 6 rats received ovariectomies with a group each receiving oil, progesterone, estrogen, or progesterone- estrogen injections. No difference was found among the groups 24 hours after a 3% body weight stomach load of 10% NaCl solution in either food intake, water intake, or body weight. The data failed to support the hypothesis. Extreme variability in the dependent measures, which correlated. with temperature and humidity fluctuations in the colony room, masked the results.
