828 EPITOME OP MODERN TREATMENT OP 



Ulcers. 



Wounds with general tendency to break down (necrosis) and 

 suppurate rather than to heal. These include ulcers at point of ear 

 (dogs) and point of tail (cattle and dogs). 



Ulcers in hind legs of horses, associated with swelling and gen- 

 eral debility. 



Gangrenous ulcers, carbuncle of coronet or foot rot in horses — 

 from injury, special infection and frost bite about the coronary 

 region. 



Indolent ulcer about the coronet of old hordes. 



Corneal ulcers and stomatitis ulcers in dogs and other animals. 



Ulcers due to carcinoma of the skin (horses and dogs) ; to tuber- 

 culosis, actinomycosis and glanders in horses. 



Decubitus, or ulcers due to pressure in lying down. 



Ulcers due to treads on coronet and to pressure of collar and 

 saddle on the neck and withers. 



Treatment — In general, the treatment Consists in destroying and 

 removing the unhealthy necrotic tissue and substituting in its place 

 a healthy wound. For this purpose we use the actual cautery, 

 curette, scissors, knife or caustics, as in the case of gangrenous 

 ulcers. For less urgent cases we may apply the stick lunar caustic, 

 tine, iodine, phenol, or strong solutions of mercuric bichloride, 

 formalin (10 per cent.), or zinc chloride. If there is much sur- 

 rounding inflammation and tissue to be gotten rid of by sloughing, 

 we should apply aseptic gauze soaked in 3 per cent, lysol and cov- 

 ered with waterproof and bandage till sloughing has proceeded and 

 inflammation subdued. Then we may dress with Peru balsam, or 

 stimulating and antiseptic powder, as calomel and iodoform. For 

 ulcers due to specific diseases see names of those diseases. Removal 

 of cause of irritation is essential, as of foreign body or dead tissue. 

 Rest of the part is also requisite, as bandaging or ear-cap in 

 case of ulcer of the ear in dogs. 



Urethritis in Dogs. 



Associated with Balanitis very often. 



At first give cathartic and light diet of milk and bread, and en- 

 force rest. Foment frequently with hot saturated boric acid solu- 

 tion and inject hot 3 per cent, solution of the same into the urethra. 

 Internally, give tine, hyoscyaiiius (m.x-xx) and sweet spirit of 

 nitre (m.xxx) with potassium citrate (gr.xv) in solution thrice daily. 

 After subsidence of more acute symptoms, inject 1 per cent, solu- 

 tion of zinc sulphate and lead acetate in combination or use 5 per 

 cent, argyrol solution, 180; or silver nitrate solution (1-16,000 to 

 1-4,000). Use boiled, soft-rubber catheter, if there is urethral ob-
