4. Injection of Disinfectants into the Ovaries. 



Quite analogous to emptying the ovarian cysts by puncture is 

 the injection of them with disinfecting ?and dispersing agents. 

 This was first recommended by Bertschy (Schweitzer- Archiv. 

 1906, p. 155) in cases of cystic ovaries, especially those under- 

 going fibro-cystic degeneration or containing central cysts. We 

 use for this purpose a Dieulofoy syringe fitted with a special 

 rubber tube from the syringe to the canula, through which we 

 inject a 1:10 Tr. Iodine solution. 



The practical results of puncture of cystic degenerated ovaries, 

 as well as the intra-ovarian injections, according to our statistics, 

 are evident only in rare cases, a fact which supports our teach- 

 ing throughout that, when cystic ovaries cannot be restored to 

 their normal condition and function by rupturing the cysts by 

 compression, either through the rectum or vagina, the last and 

 only rational resort is the uni- or bilateral castration of the 

 animal. 



When the cysts are successfully evacuated early, there is re- 

 covery from the nymphomania in from two to eight days. First 

 the sexual excitement abates ; the animal becomes more quiet in 

 from 12 to 24 hours, more docile and can again be turned with 

 the other cows to water or pasture. The sunken sacro-sciatic lig- 

 aments become normal, the vulva smaller and firmer, the vulvar 

 opening and vagina narrower and the vaginal entropium ceases. 

 Because of the contraction of the uterus and closure of the cervical 

 canal, the slimy mucous discharge ceases. The heretofore wild 

 expression of the eyes becomes again normal and docile, and in 

 a short time there is distinct improvement in the body nutrition, 

 besides a qualitative and quantitative improvement in the milk 

 secretion, changes which clearly increase the worth of the patient. 

 Within about twenty days after the operation another notable 

 result appears — the disappearance of the prolapsus vagina, or pro- 

 lapsus portionis vaginalis uteri. It is to be observed in reference 

 to the latter that the recovery occurs without vulvar sutures and 

 without the notable vulvar cicitrization, which decreases the value 

 of the animal. Only in old cases with debility are vulvar sutures 

 demanded. Furthermore, in about three weeks the normal estfum
