The effect of estrogen (17β-estradiol; E₂) replacement on the liver function was examined in ovariectomized rats. Ovariectomy decreased serum transaminase activity and physiological dosage levels of E₂ replacement returned the activity up to or above non-ovariectomized levels. Under the conditions of this experiment the elevated serum transaminase levels in the E₂ replacement were not coincident with histological changes suggestive of liver dysfunction. The elevations of both serum glutamic oxaloacetic transaminase (GOT) and serum mitochondrial GOT were accompanied by increased hepatic tissue activity, suggesting that the elevated serum levels can be attributed to the accelerated synthesis of the enzymes. On the other hand, the elevation of serum glutamic pyruvic transaminase was not accompanied by increased tissue activity in the original organs, namely liver, kidney, heart and skeletal muscle. Ovariectomy decreased serum albumin and inhibited development of rough endoplasmic reticulum in the liver, and E₂ replacement returned them up to or above the non-ovariectomized levels.
