214 Paralysis phai-yngis. 



tioiis may sometimes give relief in combination with Priessnitz' 

 applications (oil of mustard in 6 to 8% alcoholic solution, red 

 biniodide of mercury ointment 1:4). 



Abscesses should, if possible, be opened early; it is some- 

 times possible in cattle to open an abscess, previously located 

 in the pharynx by palpation, with a knife introduced into the 

 mouth (Macgillivray, Cunningham). A pharyngeal fistula 

 which has eventually formed may be made to heal within a 

 few weeks by repeated disinfection. Tracheotomy must not 

 be delayed in the presence of intense dyspnea or edema of the 

 larynx. The use of internal medicines usually appears super- 

 fluous and may even be dangerous. Should it however become 

 necessary, such medicines should be used by rectal or by sub- 

 cutaneous injections. 



Chronic pharyngitis in small animals may be treated with 

 local applications of tincture of iodine (Tinct. lodi., Tinct. 

 Gallarum aa), chloride of iron (1:6), iodine or tannic-acid- 

 glycerine, insufflations of boracic acid or tannic acid with sugar 

 (aa). In large animals treatment must be limited to irritant 

 inunctions and Priessnitz' application.

2. Paralysis pharyngis. 



{Paralysis of the Pharynx, Schlundhopflaehmung [German].) 



Etiology. Paralysis of the pharynx is especially seen as 

 a part of the clinical picture of bulbar paralysis in disease 

 of the central nervous system (meningitis, meningitis cerebro- 

 spinalis enzootica, progressive bulbar paralysis, tumors), in the 

 course of certain infectious diseases (rabies, acute infectious 

 bulbar paralysis) and intoxications (botulism) and also, as is 

 claimed, after poisoning with some fungi. 



Occasionally it develops secondarily after acute pharyngitis 

 (Bongartz) probably due to secondary affection of the glosso- 

 pharyngeal nerves or of the branches of the pneumogastric 

 nerve which supply the muscles of the phar^mx. (Zschokke 

 saw a case of paralysis of the pharynx caused by a perineuritis 

 after infection of the guttural pouch of a horse with hyphomy- 

 cetes.) Tumors compressing the pneumogastric nerve may ex- 

 ceptionally produce paralysis of the pharynx. Somethnes the 

 latter may appear as a primary condition. 



Symptoms. Paralysis of the pharynx makes deglutition 

 impossible, coiiseciuently food and water taken up are again
