Endocrine functions in atherosclerotic rabbits.

Radioimmunoassay of serum thyroid hormones (T3 and T4), testosterone, estradiol, insulin and cortisol of rabbits fed on a high-fat diet (coconut oil, cholesterol, cholic acid) for three months and developing experimental atherosclerosis (confirmed by biochemical tests and morphological changes in the aorta) have revealed an increase in the content of estradiol and insulin, and a decline in the level of thyroid hormones and testosterone.
