Section from adipose tissue in the neighborhood of a phlegmonous inflammation due to 

 infection with streptococci. (Grawitz.) F, the boundaries of fat-cells, the tissue repre- 

 sented being the connective tissue between those cells. Four large karyokinetic figures 

 are seen in that tissue ; these are in the rejuvenescent cells of the fibrous tissue. The 

 section also contains leucocytes that have wandered into the tissue from the neighbor- 

 ing focus of exudation. These are designated by the letters L and c. Ci and c 2 are con- 

 nective-tissue cells undergoing destruction, their nuclei showing chromolysis. Other 

 connective-tissue cells show a swelling of the nucleus (karyolysis), and the interstitial 

 tissue is the seat of a moderate oadema. 



produced through a similar rejuvenescence of the endothelial cells 

 of the older capillaries. Those cells become richer in cytoplasm, 

 and acquire a strong resemblance to epithelial cells (Fig. 270). 

 They then multiply, forming little collections of cells in contact at 



FIG. 270. 



Sections from granulations forty-eight hours old. (Nikiforoff.) In both A and B two capil- 

 laries are represented, a, young connective-tissue cell ; a\, karyokinetic figures in such 

 cells; 6, 6 1; & 2 , leucocytes with single, polymorphic, or fragmented nuclei, the latter suf- 

 fering karyolysis and, consequent ly, death : g, endothelial cell with nucleus in spirem 

 stage of karyokinesis, demonstrating the proliferation of those cells.
