The intestines and mesentery of the nutria (Myocastor coypus) have not been fully described. In the present study 30 adult nutrias were studied using gross dissection. The small intestine was divided into the duodenum, jejunum and ileum as usual. The duodenum started at the pylorus with a cranial portion, which dilated forming a duodenal ampulla. The ileum was located within the concavity of th...

Gum arabic (GA) is a water-soluble polysaccharide (molecular weight approximately 850 000) containing rhamnose, arabinose, glucuronic acid and galactose. The metabolism of GA has been studied in the rat. Adult male Wistar rats were given GA incorporated into either an Oxoid breeders (OB) diet or an elemental (Elem) diet. Intestinal contents were examined for precipitable GA using acidified etha...

Evidence for the occurrence of microbial breakdown of carbohydrate in the human colon has been sought by measuring short chain fatty acid (SCFA) concentrations in the contents of all regions of the large intestine and in portal, hepatic and peripheral venous blood obtained at autopsy of sudden death victims within four hours of death. Total SCFA concentration (mmol/kg) was low in the terminal i...

Synchronous cancers are defined as malignant tumours that occur simultaneously, each of which must be distinct with no possibility of one being the metastasis of the other. A 65 year old gentleman presented to us with two month history of epigastric pain associated with anaemia, loss of appetite and weight. He has no history of malignancy in his family. Colonoscopy revealed tumours at transvers...

The distributions of Cu, Zn, and Pb concentrations in the selected soft tissues (foot, cephalic tentacle, mantle, muscle, gill, digestive caecum, and remaining soft tissues) and shells of the mud-flat snail Telescopium telescopium were determined in snails from eight geographical sites in the south-western intertidal area of Peninsular Malaysia. Generally, the digestive caecum compared with oth...

verbmobil, a speech to speech translation system, poses new and challenging tasks for a dialogue component. We present a part of the dialogue component of verbmobil: a robust plan recognizer that processes all of the over 200 dialogues of the verb-mobil corpus. The recognizer currently handles unexpected sequences of input, and will in the future deal with multiple input, hypotheses, and incomp...

Articolul analizează cinematica roţii de orientare a unui robot mobil planar constituit dintr-o platformă orizontală şi două roţi convenţionale. Vitezele şi acceleraţiile caracteristice ale sistemului mecanic neolonom sunt stabilite pe baza unor relaţii matriceale de conectivitate. Cunoscând mişcarea celor două roţi motoare, se obţin expresii şi grafice pentru unghiul relativ de rotaţie şi trai...

A case of intestinal emphysema localized to the caecum is reported together with an experiment to try and reproduce the condition in vitro.

In a paper in the POSTGRADUATE MEDICAL JOURNAL we reported four cases of ' simple' ulcer in the colon. The following two examples are now presented as a sequel to this: Case i.-M.C., female, aged 14 years. This child presented with a history of two weeks' intermittent central abdominal pain; the pain was colicky, but not severe enough to incapacitate her. Two days before admission to hospital t...

Caecum, the largest part of duck’s intestine has an important role in liquid absorption, cellulose digestion and defensive mechanism. Age related changes in the histomorphology of the caeca in Kuttanad ducks were studied in 72 birds from day-old to adult at fortnight intervals. After recording the biometry and gross features, the material was fixed in neutral buffered formalin and standard proc...
