260 LAMENESS OF THE HORSE 



all cases and in some instances provision for drainage, as in 

 puncture wounds, is helpful. Locally, curettage and the j.ppli- 

 cation of suitable antiseptics are indicated. Hot fomentations 

 are beneficial and should be continued for several days if neces- 

 sary, to stimulate resolution. A brisk purge should be admin- 

 tered at the onset and strychnin, because of its indirect stimu- 

 lative effect upon the circulation together with its tonic effect 

 upon the musculature, is beneficial. 



In all such cases rational treatment, good hygiene and careful 

 nui*sing are the principal factors which stimulate recovery. In- 

 dividual resistance or lowered vitality has a marked influence 

 on the course of this affection. 



NON-INFECTIOUS LYMPHANGITIS. 



This type of lymphangitis is associated with, or the result of, 

 a derangement of digestion. It affects heavy draft horses, rarely 

 other types of animals, and involves one or both hind legs. 



Occurrence. — In healthy and well nourished horses irregu- 

 larly used, this affection may suddenly manifest itself. It oc- 

 curs in singular instances in mares that are in advanced preg- 

 nancy even when such animals are at pasture. Usually, however, 

 this malady is found in heavy draft horses that have been kept 

 stabled from one to three days. 



Symptomatology. — At the outset in severe cases, there is 

 elevation of temperature, labored breathing, accelerated pulse, 

 anorexia and more or less swelling of the affected memliers. 

 Swelling is very painful and when the affected legs are palpated, 

 pain is manifested by flinching. The inguinal lymph glands 

 are often swollen but in some cases they are not affected in any 

 perceptible degree. In the average case suppuration does not 

 occur and when conditions are favorable, resolution is complete 

 within ten days. Tlie extent of the involvement and the intensity 

 of the affection vary materially in different cases and a chronic 

 lymphangitis may succeed the acute attacks and finally in 

 some instances, elei)liantiasis results. 



Treatment. — An active purgative should be given at once 

 and in the ordinary case, stimulants are indicated. If marked 

 distress is present, morphin is given and where there is much
