Intestinal sarcoma is a relatively rare disease. It occurs much less frequently than cancer. According to Mikulich, for example, there were only 5 sarcomas per 100 cases of bowel cancer (except recti). The intestine, in comparison with other organs, is also not often affected by sarcoma. According to Nagel's notes on 247 sl. sarcomas, intestinal sarcomas were observed in 3 cases (1%)- Surgical literature is not rich in works devoted to intestinal sarcomas. Korner and Furbank collected 175 sarcomas of the digestive tract before 1907, of which 65 were localized in the small intestine. Sreese in 1914 was able to take 99 sl. intestinal sarcomas. The Russian literature on the issue of intestinal sarcoma has the works of Bondarev, Favorsky, Peacemakers and Punin. Intestinal sarcoma is more common in men (80% according to Noorden) This disease is mainly observed at a young age, from 20 to 30 years (Peacemakers, Bondarev), 30-40 (Corner, Madelung). However, sarcomas also occur at an older age. Of all parts of the intestine, sarcoma is most often found in the small intestine. So Korner and Furbank mark 65 sarcomas of the small intestine, 20 sarcomas of the blind and 11 other parts of the colon. According to Liebman, out of 50 cases in 15 sl. localization was in the 12-digit, in 18 in the skinny, in 14 in the iliac and the rest in other parts of the digestive tract. According to Staemmler (1924), for 184 cases of sarcoma of the small intestine, localization in the jejunum is indicated in 44 cases.

Excessive hunting and poaching for commercial purpose of Varanus salvator in Indonesia can cause a decline in this animal population. However, the scientific information of this animal especially about the biologic of organ system is rarely reported. Therefore, this case opens up opportunities for researching, which aims to study the anatomy of digestive tract of water monitor macroscopically. This research has been conducted in Biology Laboratory, University of Muhammadiyah Kupang for 5 months from March to August 2016. The digestive organ of this animal that has been preserved in alcohol 70% was obtained before from two males of water monitors. Preservation process: the animal were anesthetized, exsanguinated, and fixated in 4 paraformaldehyde by tissue perfusion method. Observations were performed to the visceral site and morphometrical of digestive tract. The resulted data was analysed descriptively and presented in tables and figures. The digestive tract of water monitor consist of esophagus, stomach, small intestine, large intestine and cloaca. The dimension of each organ is different based on its structures and functions. The esophagus of water monitor connects the mouth cavity and the stomach and also as the entrance of food to the stomach. Water monitor stomach were found in cranial part of abdomen, in left side of liver. The small intestine was longer than stomach and it is a winding muscular tube in abdomen in posterior side of liver. The large intestine consist of colon and cloaca, while cecum was not found. This channel was extend lateromedially in abdomen to cloaca between left and right kidneys. The cloaca was the end of digestive tract which excreted feces and urine. From this research, we can conclude that the digestive tract of water monitor consists of esophagus, stomach, small intestine, and large intestine. It’s difficult to differentiate small intestine and large intestine because there are no cecum.

1. The effect of drying and ensiling ryegrass on the site of digestion of the energy andcarbohydrate fractions was studied in sheep fitted with rumen cannulas and re-entrant can-nulas in the proximal duodenum and terminal ileum.2. The sheep were given fresh (frozen) grass, dried grass, wilted and unwilted silage pre-pared from herbage harvested from the same sward. The grass diets were offered twice dailyto each animal and paper impregnated with chromium sesquioxide was administered twicedaily into the rumen. Twenty-four hour collections of duodenal and ileal digesta, adjusted togive 100 yo recovery of Cr2O3, were analysed to determine the extent of digestion in the fore-stomachs, the small intestine and the caecum and colon.3. Total digestibility of the gross energy was similar for the fresh grass, dried grass andwilted silage diets (67·4,68·1 and67·5 %)but higher for the unwilted silage (72·0 %, P < 0·01).There was an increased flow of energy into the small intestine when the sheep were given driedgrass and unwilted silage. The proportion of the apparently digested energy lost within thesmall intestine was greater when the dried grass was given (302 yo) than when the fresh grasswas given (23·6 yo).4. Drying or ensiling of wilted material affected digestion neither in the entire alimentarytract nor in the different sections of the tract, of some carbohydrate fractions. About 97 yo ofthe digested water-soluble carbohydrate, over 90 yo of the digested cellulose and over 70 yo ofthe digested hemicellulose were digested before reaching the small intestine. The increasedamount of energy entering the duodenum of the sheep given the dried grass was notaccounted for by changes in the fate of these carbohydrate fractions in the digestive tract. Withunwilted silage, digestibilities of the cellulose and hemicellulose fractions were higher, andlower proportions of the digested carbohydrates were lost before the small intestine.

The article presents a clinical case of intestinal epithelial dysplasia (tufting enteropathy), a rare disease which relates to congenital diarrheas, has a particular clinical presentation and is life-threating. The diagnosis was confirmed by histological examination and electronic microscopy of mucous membrane of small intestine. Additional evidence is substantiated for the existence of prenatal markers of intestinal epithelial dysplasia represented as polyhydramnios and intrauterine dilatation of fetal intestinal loops. These symptoms are considered to be a clinical hallmark of sodium and chloride diarrheas and are described in single cases in enteropathy called a microvillus inclusion disease.

The nutritional nature of mammals, which has developed during a long evolution, leads to adaptive - morphological changes in their digestive tract and its immune structures, although the general laws of their structural organization are identical. The literature has data on the study of the immune structures of the small intestine under normal conditions and under the influence of certain factors. In the structure of immune structures there are numerous parallelisms, however, in each class of vertebrates, complication of this organization is achieved independently. The small intestine is an important section of the digestive tube, where the final chemical processing of the chyme and the absorption of nutrients into the body take place. However, the comparative morphology of the immune structures of the small intestine in mammals with different nutrition patterns remains poorly understood.

The electrical activity of the gastrointestinal tract and gallbladder was recorded in four sheep fed a Mg-deficient diet during 10 to 15 days. The mitigating effect of intravenous infusions of MgCl2 was tested at the end of the experimental period in animals presenting hypomagnesemia. Motility of the reticulo-rumen remained unchanged in Mg-deficient sheep except that there was no postprandial increased frequency of contractions. By contrast, the contractions of gallbladder, cecum and proximal colon were reduced in both amplitude and frequency. The amplitude but not the frequency of the antro-duodenal slow-waves was reduced. The amplitude of the regular spiking activity of the small intestine was reduced as well as the number of complexes produced per day. The activity of the spiral colon was correlated to the blood magnesium concentrations but Mg infusion was unable to restore immediately the motor profile of the rest of the gut to its intitial level. This was done within 2–3 days by changes in the diet in three of the four animals. It is concluded that the motility of the whole digestive tract, including the reticulo-rumen, is modified on a Mg-deficient diet and that hypomagnesemia, involved in the atony of the spiral colon, is only one of the factors responsible for the hypomotility.

Primary lymphoedema is a rare disorder. Often presents at a young age with asymptomatic limb oedema with gradual progression. We present a 16-year-old woman who presented with a history of swelling of the left lower limb for 6 years. There was the presence of isolated left lower limb oedema, which was a non-pitting type. The patient underwent imaging studies and was diagnosed to have primary lymphoedema. The patient was managed conservatively as the patient did not have any other problems other than the left lower limb oedema.

Neurotensin has many actions on digestive tract motility and secretion and stimulates pancreatic growth. We examined effects of chronic administration of neurotensin on growth of small intestine and colon. Four groups of 10 rats were injected with saline or neurotensin (33, 100, or 300 micrograms/kg) every 8 h for 5 days. The small intestine was divided into four segments of equal length, weighed, and assayed for DNA, protein, and brush-border digestive enzymes. The colon was weighed and assayed for DNA and protein. Neurotensin caused dose-related increases in growth of small intestine; at the highest dose, similar increases in weight (12-20%), DNA (23-35%), and protein content (33-39%) occurred in each segment of small intestine. Maltase, sucrase, and leucine aminopeptidase (but not lactase) contents were also significantly increased after neurotensin, but the largest effects were seen in the proximal small intestine. Neurotensin had no effect on weight, DNA, or protein content of the colon. These results suggest a role for neurotensin in regulating growth of small intestine.
