Study, describe and draw slides

N° 86 — purulent leptomeningitis (stained with hematoxylin and eosin). At low and high magnifications, describe thickening of the pia mater, its infiltration with some purulent exudate, vasodilatation of the pia mater. Name the type of the inflammation, the causative agent, complications and outcomes.

N° 94 — laryngeal diphtheria (stained with hematoxylin and eosin).At low magnification, describe thickening of the mucous coat with presence of the fibrin-containing exudate which reaches the submucous layer, describe the state of the vessels; make differential diagnosis between the laryngeal diphtheria and descending croup; list possible complications of intubation and tracheostomy.

N° 190 —parynchematous myocarditis (stained with hematoxylin and eosin). At low magnification, describe foci of myolysis in the myocardium, plethora of vessels, as well as focal interstitial infiltration with lymphoid cells; name the pathological process, list possible outcomes.

JNe 191 —peribronchial pneumonia in measles (stained with hematoxylin and eosin). Describe the state of lumens in the bronchi, presence of some purulent exudate in them; pay attention to metaplasia of the cylindrical bronchial epithelium into a stratified squamous one, as well as infiltration of the

bronchial wall with leukocytes. What are the main causes of the disease? List possible outcomes.
