Photomicrograph of kidney sections. Group 1 exhibited (a) normal renal architecture (× 10) and (b) uniform renal tubules and normal renal glomeruli with preserved Bowman’s space (× 40). Group 2 exhibited (c) focal relative raised congestion of capillary glomerular tufts with multiple aggregates of inflammatory cells (× 40) and (d) focal congestion of capillaries (× 40). Group 3 exhibited (e) patchy inflammatory reaction (× 40) and (f) few congested stromal capillaries (× 40). Group 4 exhibited (g) minimal inflammatory reaction (× 40) and (h) few congested stromal capillaries (× 40).
