52 DISEASES OF THE DIGESTIVE APPARATUS. 



Etiology. The same causes that would produce stomatitis 

 would bring on inflammation of the throat. The most common 

 cause of anginal catarrli is by a continuation of the inflammatory 

 processes from the neighboring organs — for instance, in catarrh 

 of the head, or in laryngitis, and it may app ar as a complication 

 of distemper. 



Eathological Anatomy, Clinical Symptoms and Course. 

 The changes of the mucous membranes are the same as are recog- 

 nized in all catarrhal inflammations. The mucous membrane is 

 a difiiased red, sometimes spotted, and coated with a dirty yel- 

 lowish mucus. It is rarely purulent on its surface, except in very 

 grave affections, when especially on its dorsal region there may be 

 seen a number of small, irregular granulations. As a rule, if the 

 inflammation is at all severe, the tonsils are also swollen and pro- 

 trude out of their membranous pouches in the shape of brownish- 

 red enlargements. We very rarely see any fibrinous (croupal) 

 membranes in any of the severe inflammations of the throat. 



The clinical symptoms of catarrh of the throat are similar to 

 acute stomatitis, and it is only by making a careful examination 

 of the throat that we can make a correct diagnosis. The author 

 has found, as a rule, that catarrh of the stomach accompanies all 

 these cases. Catarrh of the nasal passages and pharynx, and slight 

 fever are also seen in these cases. The author has never observed 

 true chronic catarrh of the throat. 



Theeapeutics. Considering the mild course of the disease 

 little medicinal treatment is desired; a liniment, such as cam- 

 phorated oil or soap-liniment, should be rubbed on the throat, 

 and sedative mouth-washes, such as boric acid and glycerin. 

 Keep the animal in a dry temperature, not too hot, and give 

 easily digested food. 



Sometimes acid or irritating agents may cause acute inflamma- 

 tions of the throat, and if they are so severe as to ulcerate they 

 may be mistaken for diphtheria or croup. In such cases wash 

 the mouth out with a solution of permanganate of potassium, boric 

 or salicycic acid, or paint the throat with nitrate of silver or f an- 

 nate of glycerin.
