12 SPECIAL VETERINARY THERAPY 



with degenerated synovia and occasionally some pus. 

 The tumor is now incised for drainage, making a 

 fairly large opening. The contents are forced out 

 completely by compressing with the fingers and then 

 an ounce or two of tincture of iodine is injected and 

 allowed to run out again immediately. Following 

 this a rapid reduction of the tumor is brought about 

 by the use of Fibrolysin (thiosinamine salycilate), 

 made by Merck & Co., and marketed in ampules con- 

 taining about 3cc each. 



One injection is made as soon as the tumor has 

 been lanced and thereafter every two or three days. 

 Two ampules are used at each treatment, injecting it 

 hypodermically at various points around the base of 

 the tumor. Fibrolysin has a selective action on 

 fibrous tissue and is of no value in enlargements of 

 other tissues or organs. 



A satisfactory, sometimes a complete, reduction 

 of the hygroma can be obtained in the course of two 

 to three weeks depending, of course, on its size.
