複選題57. Which statements accurately describe the physiological activity of eicosanoids in the arachidonic acid pathway? (A) Corticosteroids inhibit phospholipase A2, resulting in decreased levels of prostaglandins, thromboxanes, and leukotrienes. (B) Leukotrienes (LT) promotes the contraction of smooth muscle, contraction of airway, trachea, and small intestine, and increascs microvascular permeability, leading to edema. (C) Rofecoxib, a selective COX-II inhibitor, was withdrawn from the market due to its concurrent production of thromboxane while generating PGI2, resulting in myocardial infarction. (D) PGE2 (Prostaglandin E2) is commonly used as a labor-inducing agent in clinical practice mainly because it promotes the contraction of uterine smooth muscles, thereby initiating uterine contractions and facilitating the progression of labor.

複選題59. Consider the symptoms associated with bile duct obstruction due to gallstones: patients often present with upper abdominal pain, fever, and potential inflammation. Some individuals may experience gencralized abdominal discomfort without clear localization. Based on physiological characteristics and possible biochemical mechanisms, which statements accurately explain these observations? (A) Bile acids form covalent bonds with glycine through an amide linkage, raising their pKa value and augmenting their emulsifying properties. (B) Cholesterol can undergo metabolism to produce 7α-hydroxycholesterol catalyzed by cholesterol 7α-hydroxylase, a process that is expedited by elevated levels of bile acids. (C) Cholcstyranine is not a resorption resin binding to bile acid to enhance elimination. However, cholestyramine may bind to vit. A, D, E, K and inhibit their absorption. (D) Bile salts are metabolized by bacteria in the small intestine to form secondary bile acids. Oral administration of ursodeoxycholic acid, a secondary bile acid, can aid in dissolving cholesterol in bile, thereby dissolving gallstones ranging from small to medium in size.
