| intestinal malabsorption | <gastroenterology> The inadequate absorption of nutrients from the small intestine. This can result in loss of weight and abnormal appearing stools. Malabsorption can be caused by lesions of the small intestine, amyloidosis, lack of digestive enzymes (for example lactose intolerance) or bile salts or surgical operations. (10 Jan 1998) |

| intestinal metaplasia | The transformation of mucosa, particularly in the stomach, into glandular mucosa resembling that of the intestines, although usually lacking villi. (05 Mar 2000) |
| intestinal mucosa | The innermost membrane of the four coats of the intestinal wall, the other three being the submucosa, muscular layers, and serosa. (berk et al., gastroenterology, 4th ed, v.3, p1479) (12 Dec 1998) |
| intestinal myiasis | Presence of larvae of certain dipterous insects in the gastrointestinal tract, as of Musca domestica (domestic housefly), the cheese mite, and Fannia canicularis (lesser housefly). (05 Mar 2000) |
| intestinal obstruction | <surgery> A blockage of the bowel lumen prohibiting the passage of material. Common symptoms include constipation, abdominal swelling and abdominal pain. Treatment includes intravenous fluids, rest, nasogastric suction and surgery in select cases. (27 Sep 1997) |

| intestinal rotation | See: malrotation. Molecular rotation, one hundredth of the product of the specific rotation of an optically active compound and its molecular weight. Optical rotation, the change in the plane of polarization of polarised light of a given wavelength upon passing through optically active substances; measured in terms of specific rotation by polarimetry, an important tool in chemical structural work, especially on carbohydrates. Specific optical rotation ([a]), the arc through which the plane of polarised light is rotated by 1 gram of a substance per milliliter of water when the length of the light path through the solution is 1 decimeter, typically using light corresponding to the D line of sodium.
