Study, describe and draw the slides

N° 26 — glomerulonephritis in lupus erythematosus (stained with hematoxylin and eosin). Pay attention to the thickening of capillary membrane in the glomeruli with «wire loop» formation. Find hematoxylin bodies. Name the outcomes.

N° 27 —periarterial sclerosis in the spleen (stained with hematoxylin and eosin). Pay attention to the growth of connective tissue surrounding the artery, which looks like onion skin.

N° 181 — acute verrucous endocarditis (stained with hematoxylin and eosin). Pay attention to fibrinoid swelling of the cusps, verrucous plaques on them, focal lymphocytic — histiocytic infiltration on the surface of the valve. Possible outcomes of verrucous plaques on the valve.

N° 183 — rheumatic productive nodular myocarditis (stained with hematoxylin and eosin). Name the organ, find Aschoff-Talalayev granuloma. Of what cells does it consist? Where does it appear more often? What types of rheumatic nodules-granulomas are distinguished?

Study the electronograms

Immune complexes in the skin in systemic lupus erythematosus, x 30 000.

Pay attention to focal thickening of basal membranes of the arterioles, accumulation of immune complexes.

Glomerulonephritis in lupus erythematosus, x 40 000.

Pay attention to the accumulation of immune complexes under the endothelium of the glomerular capillaries, podocytes and in mesangium.
