DISEASES OF THE DOMESTIC ANIMALS 803 



subsides, use astringent injections, as 2 to 4 per cent, solutions of 

 lead acetate, zinc or copper sulphate, or silver nitrate. To avoid 

 pain of injection one may blow in a little powdered cocaine first. 

 Diachylon ointment is also useful in chronic form, and boric acid 

 , in alcohol (1-20). The occurrence of granulations in the canal calls 

 tor use of stick silver nitrate after cocainization. 



Over-Reach, Wound op Coronet From, (In Horse). 



Treat wound with continuous wet compress of 2 per cent, lysol, 

 335, for a few days, then with Peru balsam, 511, and bandage. To 

 avoid: protect coronet with pad, and rasp off toes of hind feet, 

 setting shoes back and rounding oflf toes of hind shoes, 



Oxyurides. See Parasites. 



Palpitation. See Nervous Palpitation of Heart. 



Paralysis. 



1. Hemiplegia, one-sided paralysis. Rare, due to apoplexy, cere- 

 bral thrombosis or embolism, tumor, abscess, parasites, etc. Attend 

 to bladder and rectum, change position of patient and supply good 

 bedding. Later use electricity, and administer potassium iodide, 249, 

 and strychnine, 409. Treatment generally inadvisable, as recovery 

 is protracted and partial. 



2. Paraplegia or paralysis of the posterior extremities. Treat- 

 ment depends upon the cause. Thus spinal inflammation (menin- 

 gitis), fracture, hemorrhage, tumor, may induce it. 



In Dogs, obstinate constipation, worms, indigestion, abnormal 

 dentition, nephritis, cystitis, lumbago and heart disease (disturbed 

 spinal circulation or thrombosis of the femoral arteries), occasion 

 paraplegia. Make a thorough physical examination to eliminate 

 heart disease, lumbago, nephritis and cystitis. In teething, lance 

 the gums if inflamed. Usually, thorough evacuation of the bowels 

 by castor oil and enema or manual removal of feces, and light diet 

 of broth, will lead to a cure, when constipation is a cause. If there 

 is vomiting, give 2-3 co. cathartic pills or calomel, 218, cerium and 

 bismuth by the mouth, 170, 192, and use enemata and manual re- 

 moval of feces. 



In the Horse, paraplegia occurs sometimes transiently during 

 colic, and in mares in heat. There is also an infectious enzootic 

 form. Paraplegia in the horse is often mistaken for hemoglobi- 

 nuria. Treat causative disease.
