Scatchard analysis of saturation isotherms of [125I]-iodopindolol was used to characterize beta-adrenoceptor density (Bmax) and affinity constant (Kd) in female and male hamster Harderian glands. Single-point experiments were also completed in intact females, intact males, and castrated or superior
Sexual differences on thyroxine 5'-deiodinase (5'-D) in the Harderian gland of Syrian hamsters were investigated. We compared the 24-h profile of 5'-D activity in male and female hamsters, observing a clear rhythm in males but not in females. Female values were always significantly higher than male
