vascular disease 1 ( atherosclerosis )
الجزئية هذي فقط من CVS نزلتها الجامعة حاليا شرحتها من الشيت الجديد ب الاضافات .. حاولوا تشوفو الفيديو وتقروها حنزل أسئلة اليوم عليها 💜💜 موفقين
Q1. A 60-year-old man died secondary to coronary artery disease. At the
time of autopsy marked atherosclerotic changes were present within his coro-
nary arteries. Sections from these abnormal areas revealed complicated ather-
osclerotic plaques with calcification and hemorrhage. Within these plaques
were cellular zones, composed of smooth-muscle cells and macrophages, and
a central core with foam cells and cholesterol clefts. These foam cells are
smooth-muscle cells or macrophages that have phagocytized lipid. Which
one of the following substances promotes atherosclerosis by stimulating
smooth-muscle cells to proliferate, phagocytize lipid, and excrete extracellular
matrix material?
a. Alpha-interferon
b. Beta-transforming growth factor
c. Interleukin 1
d. Platelet-derived growth factor
e. Tumor necrosis factor

to his renal arteries. Which of the following is the most likely cause of this aneurysm?
a. Atherosclerosis
b. A congenital defect
c. Hypertension
d. A previous syphilitic infection
e. Trauma
