Growth Hormones: Should We Use Them? Michelle Szalasny Dr. Juan Bouzat Sarah Wofford Biology 2040H Fall 2013 Introduction Recombinant Bovine Growth Hormone‚ also referred to as Bovine Somatotropin (rBST)‚ is a genetically engineered growth hormone most commonly manufactured by Monsanto. Monsanto sells this drug under the name of “Posilac” to dairy farmers who choose to use the growth hormone. Although most of these bovine growth hormones onl y

Actions of Thyroid Hormone and Mechanism of Graves’ Disease Thyroid hormones are capable of acting at nearly every organ system in the human body. They promote bone formation‚ increase basal metabolic rate‚ heat production‚ oxygen consumption‚ and they alter the cardiovascular and respiratory systems resulting in an increased blood flow and oxygen delivery to the tissues. A quick summary of thyroid hormone synthesis‚ taken directly from the Kopp article‚ is included at the end of this learning

that of the hypophysectomized rat’s baseline metabolic rate because it lacked thyroid-stimulating hormones. The following questions refer to Activity 2: Determining the Effect of Thyroxine on Metabolic Rate. 4. What effect did administering thyroxine have on each of the rats? It caused the metabolic rate to increase in all three rats. 5. Explain why thyroxine had these effects. It is a thyroid-stimulating hormone that causes more metabolism to occur. The following questions refer to

cause of Bado’s hypocalcemia is chronic hypoparathyroidism which is secondary to a thyroidectomy. Hypoparathyroidism may be due to a failure to respond to vitamin D or a deficiency of it or a failure to respond to PTH. With the removal of Bongo’s thyroid‚ that is what caused his low levels of blood plasma Calcium level to be where it was when it was tested. 2. a. Hypocalcemia decreases the concentration of calcium outside of cell which increases the cells excitability and lowers the threshold potential
