CHANGES IN NON-PREGNANT UTERUS 



lOI 



several Rodents (rat, guinea-pig, etc.), and has described pro(estrous 

 desquamation of the uterine epithelium, followed by recuperation. 

 The degenerative changes are accompanied by a secretion of mucus, 

 and there is a marked leucocytosis over the entire generative tract. 

 Desquamation of epithelium also occurs in the vagina. Furthermore, 

 emigration of leucocytes between the epithelium of the glands, 

 accompanied by great glandular activity, has been observed by 

 Blair BelU in the proccstrous uterus of the rabbit.

In the rabbit pseudo-pregnant uterine hypertrophy only occurs 

 usually under experimental conditions," as when the doe has 

 copulated with a buck in which the operation of vasectomy (or 

 severance of the vasa deferentia) has lieen performed so that 

 spermatozoa cannot be ejaculated, or where the female has had the 

 Fallopian tubes severed. Under such conditions the corpus luteum 

 (see p. 149) is formed in the ovary. The uterus undergoes growth, 

 vascularisation and extensive glandular development followed by
