Micro-X-ray fluorescence(μ-XRF)and micro-X-ray absorption near edge structure(μ-XANES)have not been widely used in animal *** situ determination of iron distribution and oxidation state in broiler duodenal wall was done byμ-XRF andμ-XANES *** newly hatched healthy(1-day-old)Arbor Acres commercial male broilers were used in this *** chicks were fed a corn-soybean meal basal diet(96.00 mg of Fe/kg diet)from the 1st day to the 21st day,but were fed a semi-purified diet(12.50 mg of Fe/kg diet)after 21 days to deplete the body Fe *** the 28th day,after an overnight fast,all the birds were randomly allotted to four different Fe sources[FeSO4,Fe-Gly(II),FeCl3 and Fe-Gly(Ⅲ)].Three points five mL nutrient solution was injected to a broiler’s duodenum by technology of in situ ligated intestinal loops and a perfusion group without Fe sources added to the media was designed to exclude the effect of endogenous *** incubated for 30 min,duodenal midpieces sections were collected for analyses byμ-XRF andμ-XANES *** was found that Fe concentration for ferrous Fe sources[FeSO4 and Fe-Gly(Ⅱ)]was significantly higher than that for ferric Fe sources[FeCl3 and Fe-Gly(Ⅲ)]in the duodenal wall,moreover,Fe-Gly(Ⅱ)group samples had the largest amount of Fe.μ-XANES spectra of Fe for the four sources were basically the same in the duodenal wall,which indicated that despite the ferric iron supplied to duodenum,ferrous iron could also be absorbed into the duodenal wall.

Intra-abdominal aggressive fibromatosis is a locally aggressive tumor mostly originating from the mesentery or retroperitoneal space, infiltrating adjacent tissues, and very rarely metastasizing to distant organs. There are only two case reports in the English language literature where intra-abdominal aggressive fibromatosis originated from the intestinal wall. In this study, we aimed to report a case of aggressive fibromatosis originating from the muscularis propria layer of the duodenum and invading pancreas. Another interesting aspect of this case is that a primary paraduodenal hydatid cyst was incidentally detected in the surgical specimen. A 46-year-old female patient presented to our clinic with postprandial nausea and vomiting. A contrast-enhanced abdominal computerized tomography revealed a mass lesion with a size of 100 mm × 80 mm which originated from the distal pancreas and compressed the gastric pilor externally. Upon exploration the distal part of duodenum, proximaljejunum, and pancreatic mass were noted to form a conglomerated structure. Therefore, the fourth part of the duodenum, a 25 cm part of the proximal jejunum, distal pancreas, and the spleen were excised enbloc. The pathology report of the specimen indicated fibromatosis with a diameter of 55 mm that originated from the muscularis propria of the duodenum and extended into the pancreatic parenchyma. There was also an incidentally detected 10 mm paraduodenal hydatid cyst. No tumor recurrence was detected at a follow-up period of 24 mo. In conclusion, the most ideal treatment of desmoid-type fibromatosis is surgical resection of the mass lesion with clean surgical borders. Although rare, this tumor may originate from the intestinal wall. Histopathological verification is of great significance for a proper diagnosis.
