CM (A). HO-1 staining of tissues from cerebral malaria cases showing apparently absent physical brain pathology. A and B brain, C and D lung, and E and F liver, the left hand column (A, C and E) being from case 22, an example of the more common (8 of 11) combination, in which cerebral vasculature monocytes were quiescent. B, D and F are from case 38. As in both examples, monocytes in lung, and Kupffer cells, were commonly (6 of 11 and 9 of 11 respectively) strongly stained. Scale bar, 100 μm.
