None. TSH is a signal fo rthe thyroid to make and release more thyroid hormone. If the thyroid is removed TSH wil have no effect.
Hypophysectomized rats do not have the thyroxine with which to regulate metabolic rate properly. Thyroxine replacement can allow for the normalization of the metabolic rate (as it does in humans with hypothyroidism!).
Propylthiouracil is a drug given to patients with goiter to decrease or slow down basal metabolic rate.
Thyroxine is a thyroid hormone that regulates metabolism in the body. When injected into a rat, an excessive amount of thyroxine can lead to a hyperthyroid state, which can cause a decrease in metabolic rate due to negative feedback mechanisms in the body. This decrease may be a result of the body's attempt to maintain homeostasis by slowing down metabolic processes.
Normal TSH levels for adults are 0.5-5.0 mU/L.
TSH levels show ranges. For newborns TSH normal levels should be: 3.0-20 mIU/L. For adults up to age 60 TSH normal levels should be: <10 mIU/L For adults older than 60 TSH normal levels should be: Males: 2.0-7.3 mIU/L Females: 2.0-16.8 mIU/L
Yes, a TSH of 1.08 is within the normal range.
To have a normal tsh result one should be given prophythiouracil or synthroid for life.
