Hemorrhagic

Lesions

of the

Coronary

Arteries.

Hemorrhagic lesions were observed in the wails of the coronary arteries in 54 of 135 hearts (40 per cent) and were directly or indirectly related to acute occlusion of the coronary artery in 40. The lesions were characterized by hemorrhage associated with the presence of large lipoicl-containing cells, proliferative intimal changes, and organization. Smaller: less active lesions usually were found adjacent to calcified plaques. The intimal changes that coexisted with the hemorrhage appeared to represent the primary factor in the pathologic condition: the hemorrhage was secondary. It does not seem logic:tl. moreover, that hemorrhage in itself can have protlucdell the effects ol)srt\-etl.

of the Renal Arterioles

in Pregnancy.

A case is reported of chronic unilateral hematuria in a colored female, Zl years old, who was cured by nephrectonlg during the fifth month of pregnancy. The removed kidney revealed unusual, massive, medial hyperplasia and hypertroph> of the arterioles. There was accompanying intimal fihromuscular hyperplasia of the interlobular branches of the renal artery. Focal fresh hemorrhagic erosions were found in the pelvis and ureter. The medial hypertrophy could not be accounted for 1,~ any known or demonstrable injury. A hypothetical explanation is offered, based on the theory that hormonal activity during pregnancy might he responsil)le for changes in the arteriolar smooth muscle comparable to those found in the grayid uterus.
