[Two cases of colitis cystica profunda in dogs].
Colitis cystica profunda in dogs has been diagnosed in one case only. The two own cases were characterized by repeated, partly bloody diarrhea, vomitus, and painful defecation. The disease was diagnosed by clinical examination and colonoscopy with the ensuing histological examination of biopsy specimens. The disease could be managed by administration of a diet, sulfasalazine and corticosteroids.

[The ultrastructure of mixed mammary gland tumors in bitches. IV. The incidence of myoepithelial cells in formation of spindle cells (author's transl)].
Spindle cells of myomatous formations of 19 canine mixed mammary tumors were studied by light and electron microscopy. The EM findings indicate that the spindle-shaped tumor cells are mostly of myoepithelial origin. However there were also formations of spindle cells which consisted of fibroblasts or fibrocytes. By light microscopy they are not always clearly distinguishable.

[The ultrastructure of mixed mammary gland tumours in bitches. III. The early stages of the myoepithelial proliferation (author's transl)].
The early stages of myoepithelial proliferation in 14 mixed canine mammary tumours were studied by light- and electron microscopy. Two different early stages can be distinguished: 1. Proliferations inside the basal lamina with partial maintenance of the organoid pattern. 2. Proliferations with a break through the basal lamina and transposition of tumour cells into the surrounding connective tissue. The intracytoplasmic fibrillae of myoepithelial tumour cells are striped periodically and thicker than those of normal myothelia. It is suggested that the amorphous as well as the fibrous intercellular substance in the early stages is derived from the described myoepithelial tumour cells.
