food intake of rats increases during pregnancy. this requires changes in the structure of the small intestine to absorb additional food. the aim of the present study was to investigate the morphological changes in the layers of small intestine in rats during pregnancy. duodenum, jejunum and ileum of 18 pregnant sprague-dawley rats (day 7, 14 and 21 of pregnancy) were collected. villous height a...

Yue X., Hu L., Fu X., Lv M., Han X. (2017): Dietary chitosan-Cu chelate affects growth performance and small intestinal morphology and apoptosis in weaned piglets. Czech J. Anim. Sci., 62, 15–21. The effects of dietary chitosan-copper chelate (CS-Cu) on growth performance, diarrhea, intestinal morphology and epithelial cell apoptosis in weaned piglets was investigated. One hundred and sixty Dur...

Various complications of hydatid cyst have been recognized to date. We have encountered one such complication-rupture of hydatid cyst to the duodenum­ leading to upper gastrointestinal bleeding in a 40 year old male, who referred with severe right upper quadrant (RUQ) pain and gastrointestinal bleeding of a few hours' duration. Laparotomy revealed a cyst (7 x 15 cm) in the left lobe of the ...

The goal of research. To analyze some features peptic ulcer the stomach and duodenum in children, depending on type constitution. Material methods We examined 58 children aged 12-18 years with a diagnosis and/or duodenum, who underwent endoscopic examination, Hp was detected biopsy aero test. Results. Peptic disease more often asthenic (67.2%), less hypersthenic (17.3%) normosthenics (15.5%). V...

A 55-year-old Japanese man without dyslipidemia underwent esophagogastroduodenoscopy screening. He was diagnosed with reflux esophagitis, atrophic gastritis, and multiple gastric ulcers. In addition, scattered white villi were seen in the superior duodenal angle. No white villi were seen in any other parts of the duodenum. Esophagogastroduodenoscopy performed three months after Helicobacter pyl...

We report two patients with primary adenocarcinoma of the duodenum who underwent successful pancreatico-duodenectomy (modified Whipple operation). One patient died from an unrelated cause three years following surgery whilst the other remains well and clinically free of disease 3 years after resection. An aggressive surgical policy in patients with this rare tumour seems justified.

Gangliocytic paragangliomas are rare benign tumors which are usually encountered in the second portion of the duodenum. Histogenesis of these tumors is incompletely understood. Patients usually present with upper gastrointestinal bleeding. The endoscopic features of gangliocytic paraganglioma do not differ from those of other submucosal tumors. Therefore, they can be diagnosed histologically by...

We present the first report of an immature teratoma arising from a germ cell testicular cancer invading the duodenum. While other seminomatous and non-seminomatous germ cell tumors are known to metastasize to the duodenum, this is the first such case involving an immature teratoma directly invading the duodenum from a metastatic retroperitoneal mass.

We report a case of squamous cell carcinoma of uterine cervix metastasizing to the duodenum through lymphatics. Para-aortic group of lymph nodes were involved which ultimately infiltrated the duodenum. On endoscopic examination, peri-ampullary growth was noted. Endoscopic biopsy from the growth was studied by routine histopathology and metastasis of squamous cell carcinoma involving duodenum wa...

At the end of the embryonic period of human development, c-kit immunoreactive (c-kit IR) cells identifiable as interstitial cells of Cajal (ICC) are present in the oesophagus and stomach wall. In the small and large bowel, c-kit-IR cells appear later (in the small bowel at 9 weeks, and in the colon at 10-12 weeks), also in the MP region. The object of this study was to determine the timing of a...
