[Experimental autograft of the small intestine in the pig. Histological, histoenzymological and ultrastructural study]. 1975

G Chomette, and M Cerf, and J M Hay, and J L Preel, and H Garnier

In order to form an opinion of the value of certain precocious rejection tests with a view to ulterior intestinal allograftings, the authors intend first of all to determine the consequences of the operation itself and of the possibility resulting anoxia on the function of the intestinal mucosa. A concomitant biological (xylose test meal, quantitative analysis of the enzymes of the mucosa) and morphological study (lipid test meal, histologic, enzymologic and ultrastructural study of biopsic specimens) was carried out at various intervals after orthotopical intestinal autografting in 22 pigs. Most of the biological tests were strongly perturbated on the 7th day and some of them did not resume their initial value until the 15th day. The morphological and especially ultrastructural studies showed up to that time an important inflammation apparently caused not by the anoxia but by the lymph stasis. Solely conventional histology was only sightly modified (absence of ulcerations and of denudation of the villi) and this relative integrity, contrasting with the known severity of the lesions in case of precocious rejection, allows to consider this examination the only valuable until the 15th day, for the detection of immunologic incompatility reactions in allograftings.

UI	MeSH Term	Description	Entries
D007249	Inflammation	A pathological process characterized by injury or destruction of tissues caused by a variety of cytologic and chemical reactions. It is usually manifested by typical signs of pain, heat, redness, swelling, and loss of function.

D007408	Intestinal Absorption	Uptake of substances through the lining of the INTESTINES.	Absorption, Intestinal
D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D007421	Intestine, Small	The portion of the GASTROINTESTINAL TRACT between the PYLORUS of the STOMACH and the ILEOCECAL VALVE of the LARGE INTESTINE. It is divisible into three portions: the DUODENUM, the JEJUNUM, and the ILEUM.	Small Intestine,Intestines, Small,Small Intestines
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).
