620 STATE BOARD OF AGRICULTU'RE]. 



necrotic zone has largely sloughed and the surface is more generally covered 

 with epithelium. At places the epithelium is only six to eight microns in 

 height, at other places it shows extensive budding and is in excess of the nor- 

 mal height. There is no apparent leucocytic infiltration of the stroma, no 

 marked fibrosis and the sub-epithelial zone is assuming a more normal con- 

 dition. 



Case No. 6 



'Clinical Condition and Treatment : The record of the clinical examination 

 of this case before treatment was lost. Two ounces of menthol-iodine-glyce- 

 rine preparation was injected into the uterus and the cervix swabbed with 

 the same preparation. The cow was slaughtered seventy-eight hours after 

 treatment. 



Macroscopic Examination: There is about one ounce of mucus exudate 

 streaked with pus, in the vagina. The vaginal mucosa shows a few small 

 hemorrhages. The dorsal portion of the cervical mucosa is considerably 

 congested. There are a few hemorrhages on the crests of the transverse folds, 

 particularly in the posterior half of the cervix. Aside from the dorsal portion, 

 the mucosa of the anterior half is more nearly normal. There is no coagulum 

 in the uterine cavity. The color of the mucosa is a fairly uniform slightly 

 grayer than the normal mucosa. There is present a small quantity of mucus 

 and the mucosa is moi.st and glistening. 



Histological Examination: Except for some mucoid degeneration of the 

 epithelium and a few sub-epithelial hemorrhages, the cervical mucosa is 

 normal. The uterine mucosa is covered with epithelium, although in places 

 it is only four to eight microns in height. There is a more or less distinct sub- 

 epithelial zone in which there is some leucocytic infiltration. There are no 

 alterations in the deeper portions of the stroma. Here and there, near the 

 surface a gland is seen in which there is an epithelial cast. In these cases the 

 glandular epithelium has been regenerated. Occasionally a distinct localized 

 small round cell infiltration of the sub-epithelial zone is seen. (It is surprising 

 that so few alterations are seen in this case.) 



Case No. 7 



Clinical Condition and Treatment: The vaginal and cervical secretions 

 were slightly more abundant than is seen normally. The ventral portion of 

 the second transverse cervical fold was hypertrophied and congested. No 

 alterations of the uterus could be detected. One ounce of undiluted Lugol's 

 solution was injected into uterus and the cervix swabbed with the same 

 preparation. The animal was slaughtered eleven days and five hours after 

 treatment. 



Macroscopic Examination: The ventral portion of the second transverse 

 fold of cervical mucosa is hypertrophied but the color is normal. There is a 

 small quantity of slightly adhesive clear exudate in cervical canal. The uterine 

 mucosa is a uniform, yellowish gray color. There is no abnormal exudate. 



Histological Examination: There are no alterations of the cervical mucosa. 

 The mucosa of the right horn is covered by a continuous layer of epithelium. 

 The sub-epithelial zone of the stroma does not appear to be as cellular as is 

 seen in the normal uterus. There are no other alterations of the right horn. 

 The mucosa of the left horn is also covered by a continuous layer of epithelium. 

 There is no distinct sub-epithelial cellular zone but this layer is more fibrous
