by the actual cautery and blisters. In dogs, one may try to 

 suture the torn tendon. 



Give the symptoms of tendon rv/ptwre. 



Vary greatly -with, the tendon involved. There are 

 always functional disturbances, as excessive volar or dorsal 

 flexion. A gap may be felt and seen, increasing on exten- 

 sion (flexor tendon) or on flexion (extensor tendon). 



INFLAMMATION. 



Define inflammation. 



Inflammation, not being a definite disease, cannot be 

 defined. It represents the response of tissues irritated by an 

 injury with a highly complicated reactive process. 



What are the phenomena of inflammation ? 



1. A reflex vasomotor paresis producing a dilatation of 

 the arteries, veins and capillaries of the inflamed tissues. 



2. Followed at the same time by a great increase in the 

 rapidity of the flow of blood (hypersemia), succeeded by a 

 slowing and finally stopping of the blood current. 



3. Concurrently with the slowing of the blood current 

 the white blood corpuscles begin to line up and crowd along, 

 the vessel's wall (especially the veins), the red cells continuing 

 to flow along the centre of the blood current. This condition 

 is followed by the emigration of the white blood corpuscles 

 into the surrounding tissues (diapedesis) from the interior of 

 the veins through the walls of the vessel in the direction of 

 the irritating element (chemiotaxis), which represents the 

 condition commonly termed "cellular infiltration of the 

 inflamed tissue."
