CHRONIC NASAI. CATARRH. NASAL GLEET. 

 • OZCENA IN THE HORSE. 



Chronic catarrh in horse, simple form, loss of tone, inflammation, nature 

 of discharge, glandular swellings, differentiation from glanders. Treat- 

 ment, astringent, tonic, stimulant, hygienic, locally astringents, antiseptics, 

 injections. 



A chronic discharge from the nose is often seen in the horse as ■ 

 a sequel of coryza or sore throat, or as an attendant on other 

 affections of the upper air-passages, and the different conditions 

 productive of this symptom may here be noticed. 



1ST. SIMPLE NASAL CATARRH. NASAL GLEET. OZCENA. 



In long standing coryza the nasal mucous membrane becomes 

 relaxed, fails to acquire its lost tone and continues to pour out a 

 mucopurulent product. This is really a persistence of inflamma- 

 tion of a low type, under the influence of which the membrane 

 secretes pus in place of its normal mucus. The discharge is 

 white, thick, creamy, has little tenacity, and flows uninterrupt- 

 edly. There may be slight enlargement of the submaxillary 

 glands, and if the case is of long standing and the patient in low 

 condition sores may appear on the mucous membrane. These 

 ulcers are di.stinguished from those of glanders by the absence of 

 the unhealthy angry aspect and excavated borders of the latter, 

 by the absence of the small nodular deposits on the mucosa, by the 

 less viscid nature of the secretion, and by the absence of submaxil- 

 lary swellings, or if these exist, by their being less nodular, less in- 

 durated and less firmly attached to surrounding parts. The coinci- 

 dence of ulcers and submaxillary swellings is always, however, mat- 

 ter for the gravest suspicion, and such cases should, as a rule, be 

 subjected to the mallein test. (See Glanders and Farcy). 



Treatment. In simple nasal catarrh, due alone to the relaxation 

 of the mucous membrane, the internal use of tonics and the local 

 application of astringent solutions to the nose rapidly restore the 

 parts to a healthy state.
