572 Veterinary Medicine. 



Treatment is usually the treatment of the primary disease. In 

 glanders, tuberculosis, lymphadenoma, or leucocythemia there is 

 little to hope for. Nor is there much in hepatic cirrhosis, obstruc- 

 tion of the vena cava or valvular disease of the heart. In simple 

 hypertrophy we may resort to quinia or other bitters, eucalyptus, 

 saline laxatives, exercise in the open air and sunshine, and local 

 currents of electricity. 



SPLENIC HYPERTROPHY IN RUMINANTS. 



A moderate hypertrophy is the rule in the case of cattle which 

 have passed through the Southern cattle fever, but have con- 

 tinued to live within the area of its prevalence. Gamgee's ob- 

 servations in 1 868 were very conclusive on this point. In over i ,000 

 western cattle the average weight of the spleen was 1.45 lb., 

 in 441 Cherokee (Indian Territory) cattle the average was 

 2.34 lbs., and in 262 Texas cattle the average was 2.66 lbs. 

 All these animals were killed for beef, in what was considered to 

 be perfect health. The difference relative to the weight of the 

 entire animal is even greater than is indicated above, for at that 

 date even more than at present, the Texas steer was a small and 

 thin animal in comparison with the portly western bullock. 



In lymphadenoma the organ may weigh 241b. (Tannenhauser); 

 in simple hypertrophy it has been found to weigh 37 lbs. (Koch). 

 There was usually a marked increase in the size and number of 

 the Paccinian bodies, and hyperplasia of the fibrous reticulum, 

 while the pulp might be deficient and the cut surface rather dry. 

 The adjacent lymph glands are usually enlarged. 



Symptoms. Unless in the case of excessive increase, no symp- 

 tom is usually observable, apart from leucocythsemia. With 

 enormous hypertrophy the enlarged organ may be recognized by 

 palpation, percussion, and perhaps rectal exploration. 



Treatment is unsatisfactory apart from the control and arrest 

 of the primary diseases. For simple hypertrophy, bitters, laxa- 

 tives and electricity may be tried.
