- 11. Hyperthyroidism: hyperexcitability, sleep disturbance, asthenia, fervescence, tachycardia, exophthalmus, enlargement of the thyroid gland.
- 12. Antithyroid drugs Inhibiting thyrotropic hormone production in the anterior pituitary lobe: iodine, diiodotyrosine Inhibiting thyroid hormone
- 14. Thiamazol and carbimazole block peroxidase, reduce iodization of tyrosine, reduce the formation of mono-, diiodtyrosin, their
- 16. Calcitonin inhibits bone resorption by direct action on osteoclasts and promotes calcium deposition by osteoblasts. It
- 17. Parathormone is a polypeptide. It increases the palsma calcium level. It activates hydroxylase, which converts calcidiol
- 19. Diabetes mellitus is a metabolic disorder characterized by hyperglycaemia, glycosuria, hyperlipidaemia, negative nitrogen balance and sometimes
- 21. Insulin is a two chain polypeptide. It is synthesized in the β cells of pancreatic islets.
- 23. Insulin acts on specific receptors located on the cell membrane. There are many receptors in liver
- 25. Insulin inhibits the conversion of aminoacids into glucose (gluconeogenesis). It stimulates protein synthesis and promotes storage
- 27. Preparations of insulin: highly purified pork/beef insulins; recombinant human insulins; insulin analogues. Ultra-short-acting insulin: I. Lispro,

- 36. Repaglinide and Nateglinide are KATP channel blockers with a quick and short lasting insulinemic action. They
- 37. Metformin ↓absorption of glucose from the intestine, ↑ its uptake by the muscles, ↑ glycolysis, ↓gluconeogenesis,
- 39. Glucagon-like peptide-1 (GLP-1) is an important incretin released from the gut in response to ingested glucose.
- 40. Exenatide is a synthetic DPP-4 resistant analogue of GLP-1 and activates its receptors. It is injected
- 41. Acarbose is a blocker of α-glucosidase. It ↓digestion and absorption of carbohydrates in the small intestine.
