462 THE PRACTICE OF VETERINARY MEDICINE. 



SUPPRESSION OF URINE. 



By suppression is meant functional inactivity of the 

 kidneys. The term ' ischuria ' is often applied indiscrimi- 

 nately to this condition and retention of the urine. 



Symptoms. — The animal, in a well-marked case of sup- 

 pression of urine, is duller than usual. The urine is passed 

 only in small quantities, but is normal in appearance. 

 Examination per rectum reveals the bladder empty, or 

 nearly so. 



Treatment. — Treatment merely consists of the administra-

 usual-sized doses. It is good practice also to administer a 

 dose of digitalis. If inflammatory action is suspected to 

 exist in connection with the kidneys, diuretics should be 

 withheld until the inflammation can be allayed. 



CYSTITIS. 



Inflammation of the bladder may occur in all animals 

 possessed of that organ. It is, however, not of very common 

 occurrence. 



Causes.— It sometimes follows diflicult parturition, and 

 may also be caused by exposure to cold and wet weather, 

 the administration of irritant medicines, or diuretic medi- 

 cines in excessive doses, especially if long continued. It 

 sometimes results from the absorption of cantharides from a 

 vesicant in which cantharides is used. 



Symptoms. — The patient manifests considerable pain, the 

 pulse is cjuickened, and febrile symptoms are exhibited in 

 a form more or less marked ; the mouth is hotter than 

 usual, and the bowels are usually constipated. In some 

 cases the gait of the patient may be somewhat straddling. 

 The animal urinates frequently, this being the prominent
