Thyroidectomy is removal or partial removal of the Thyroid gland.
The surgical terminology suffix "-ectomy" was taken from Greek εκ-τομια = "act of cutting out"
how could you treat a thyroidectomized rat so that it functioned like a 'normal' rat?

If an animal has been thyroidectomized, it would be missing thyroid hormones such as thyroxine (T4) and triiodothyronine (T3) from its blood. These hormones play important roles in regulating metabolism, growth, and development in animals.

Hypothyrodism because there is no thyroid.
There is no longer a thyroid, so it results in hypothyroid.
The weight in grams of the Thyroidectomized rat seemed to decrease when injected with propylthiouracil. Injected with tyroxine caused an increase in grams and ml of O2 levels do to the fact that tyroxine (a hormone from tyroid gland) increase the basal metabolic rate. ATT; Veronica V.
Thyroidectomy is the process of removing the thyroid. The result is hypothyroidism if not treated with thyroid hormone. Thyroidectomy is sometimes done to treat hyperthyroidism.
Propylthiouracil is an additive that reversibly abolishes thyroid function and the thyroid controls how quickly the body burns energy.
If an animal has been thyroidectomized, the missing hormones in its blood would be triiodothyronine and thyroxine. The thyroid-stimulating hormone is created in the pituitary gland.
Thyroxine(secreted by the thyroid gland) increases oxygen uptake(and along with it metabolism) in all tissues of the body(except brain and RBC).Thus,thyroidectomy causes a derease in BMR in the rat(compared to a normal rat). http://answers.yahoo.com/question/index?…
The only effect of TSH (Thyroid Stimulating Hormone) is to stimulate the thyroid gland tissue to produce thyroxine. If there is no longer a thyroid gland to stimulate, the TSH is produced in great abundance, but with no effect.
