Endocrine Pharmacology Study Roadmap

🔹 1. Thyroid Physiology & Pathophysiology

🔸 Physiology

• TRH (hypothalamus) → stimulates TSH (anterior pituitary) → stimulates T3/T4 release (thyroid)

• T3 = active, T4 = prohormone

• Feedback loop: T3/T4 inhibit TRH and TSH

• T3/T4 actions:

  • ↑ Metabolic rate, heart rate, cardiac output

  • ↑ Oxygen consumption, lipolysis, glucose metabolism

  • CNS effects (mood), reproductive effects

🔸 Synthesis

• Iodide uptake → oxidation to iodine → binds to thyroglobulin → forms MIT/DIT → forms T3/T4

🔸 Disorders

• Hypothyroidism: Hashimoto's thyroiditis, iodine deficiency, thyroidectomy, myxedema coma

• Hyperthyroidism: Graves' disease, toxic adenoma, thyroid storm

🔹 2. Thyroid Pharmacology

🔸 For Hypothyroidism

• Levothyroxine

Relational Schema with Functional Dependencies

• Schema: R(A, B, C, D, E, F)
• Dependencies: C → F, E → A, EC → D, A → B

1. Candidate Keys: CE
2. Prime Attributes: C, E
3. Second Normal Form (2NF):
   • No, because of partial dependencies:
     • C → F (partial dependency)
     • E → A, B (partial dependency)

EMP_DEPT Table Analysis

1. Functional Dependencies:
   • Ssn → Ename, Bdate, Address, Dnumber, Dname, Dmgr_ssn
   • Dnumber → Dname, Dmgr_ssn
   • Dmgr_ssn → Dnumber, Dname
   • Dname → Dnumber, Dmgr_ssn
2. First Normal Form (1NF):
   • Split names into first_name and last_name.
3. Second Normal Form (2NF):
   • Already in 2NF because there are no partial dependencies.
