Morphological characteristics of group 3. (a) Group 3: infiltrate zone. Extravascular arrangement of numerous erythrocytes and many macrophages containing green granules. (b) Group 3. boundary zone. Blood stagnation in capillary tubes. (c) Group 3: normal cortex, according to the structure of neurons, surrounding a damaged zone. Noticeably widened capillary tube with erythrocytes accumulated inside and pressed into rouleaux formation. (d) Group 3: extravasate. Macrophages containing pale granules. Semi-thin section. (e) Group 3: blood vessel in the infiltration zone. A circle of macrophages with green granules surrounds the vessel. Semi-thin section. (f) Group 3: blood vessel in the infiltration zone (more destroyed than (e)); a sphere of dark macrophages surrounds the vessel. Semi-thin section. The scale bars in (a)–(f) are 20 μm.
