The similarity of their contents therefore to yolk is very remarkable, and it may be suggested that the hormones absorbed from the ovum or embryo in the uterus acts upon the follicular cells in such a way as to cause them to secrete substances which in the ancestor were passed on to the ovum and formed the yolk.
It may also follow a follicular tonsillitis or some infection of the mouth or throat with or without arthritis. Tuberculosis may also occasionally cause an endocarditis. Organisms may be found in a terminal simple endocarditis due to a chronic disease, as tuberculosis or cancer; such inflammations may have been caused by circulating toxins.
Numbers of ova die without reaching maturity, the follicular cells degenerate, and the follicle becomes filled with the cells of the theca interna, which have a resemblance to those of the true corpus luteum. These degenerate follicles have been termed spurious corpora lutea, or atretic vesicles. The interstitial cells are the remains of these atretic vesicles.
Wash carefully once a week, using the ointment when skin is dry, or the lotion to allay irritation. Contagious Skin Diseases. These are usually called mange proper and follicular mange, or scabies. I want to say a word on the latter first. It depends upon a microscopic animalcule called the Acarus folliculorum.
In one part of this organ the tubules were larger than elsewhere, and one of them exhibited spermatogenesis in progress. The left and larger gonad had a quite similar structure, but at its lower end were found two ova enclosed within a follicular epithelium.
Treatment. The solid varieties of odontoma can usually be shelled out after dividing the overlying soft parts. In the follicular variety, it is usually sufficient to excise a portion of the wall, scrape out the interior, and remove any tooth that may be present. The cavity is then packed and allowed to heal from the bottom. #Fibroma.# A fibroma is a tumour composed of fibrous connective tissue.
Moreover, the hypertrophied follicular cells which constitute the corpus luteum secrete fat which is seen in them in globules.
The follicular odontoma, also known as a dentigerous cyst, is derived from the distension of a tooth follicle. It constitutes a cyst containing a viscid fluid, and an imperfectly formed tooth is often found embedded in its wall. The cyst usually forms in relation to one of the permanent molars, and may attain considerable dimensions.
When the soft-coated dogs are clipped they are operated on, say, two or three months before they are wanted, and the hair gets a chance to grow, but even then it is easily discernible, and anyone who, like the writer, has any experience of clipping dogs in order to cure them of that awful disease, follicular mange, knows what a sight the animal is when he grows his coat, and how terribly unnatural he looks.
