348 BOVINE OBSTETRICS 



Internally such animals may receive antiseptics, such as 

 camphor with oleum terebinthina salve and salicylate of soda. 



In purulent arthritis the principles of surgery come into 

 play. 



2. Metastatic Synovitis. 



In most cases the sheaths of the flexor tendons on two or 

 more legs are involved. 



Symptoms. — The animal shows a stiff and painful walk. 

 They lie a great deal, appetite has decreased, and the lacteal 

 secretion is considerably less. Local examination reveals that 

 the tendon sheaths are swollen, warm and painful. Metastatic 

 synovitis may accompany polyarthritis or exist per se. 



The prognosis is quite favorable when only one or two legs 

 are diseased. Should all legs be involved, the danger of 

 decubitus, especially in old, emaciated cows, is present. Prog- 

 nosis in those cases is doubtful. In the latter instance a 

 great deal may be done by timely interference. 



Therapeutics. — When the os uteri is still open, antiseptic 

 irrigations of the uterus are indicated; internally antiseptics 

 are to be administered. The diseased sheaths are treated with 

 Priessnitz fomentations. In cases of a chronic nature, massage 

 with iodine ointment is indicated. In purulent inflammations 

 the sheath must be opened, an incision being preferable to 

 puncturing it with the trocar ; that this is to be followed by an 

 antiseptic dressing is necessarily a matter of course. 



3. Chronic Parametritis. 



JEtiohgy. — Chronic parametritis is a chronic inflammation 

 of the annexes of the uterus, which depend probably on a 

 pysemic infection from the uterus and in which the process 

 localizes itself at first in the wall of the uterus and tin 1 

 mesometrinm. 



Pathological Anatomy . — The lymph vessels of the submucosa 

 receive the infectious material, carrying it through (In' balance 

 of the uterine wall and through the annexes as far as the 

 Lumbar glands, where farther spread is often stopped.
