Histology Report Myocardial Reference Slides 8 – 12 Hours After Myocardial Infarction (MI) Normal Heart Tissue Increased number of black dots indicates inflammation.

2 – 4 Days After MI Shows Loss of Muscle Tissue Healing MI Myocardial Reference Slides White tissue indicates healing - granulation of tissue. Increased number of black dots indicates inflammation. Healthy tissue with good blood supply

Myocardial tissue slide from Case Number: 55269M White tissue indicates scarring. Some healthy tissue with good blood supply Fat vacuoles

Lung Tissue Reference Slide Normal Lung Tissue

Lung tissue from Case Number: 55269M White spots indicate talc granules found in the lungs. Talcum powder is a soft metal and is often mixed with illicit drugs Talc is not soluble and will remain in the lungs indefinitely.

Coronary Artery Reference Slide Normal Coronary Artery with blood in the center and the artery wall surrounding it.

Coronary artery tissue from Case Number: 55269M Blockage Open area for blood to flow

Brain Tissue Reference Slide Normal Brain Tissue The dark purple, almost triangular areas are neurons. The purple circles are glial tissue
