BACKGROUND AND AIMS Mapping the geographical distribution of duodenal ulcer in relation to staple diets, and experiments on animal peptic ulcer models suggested that the lipid fraction in certain foodstuffs had a protective effect which was most marked in the lipid obtained from Horse gram (Dolichos biflorus). Lipid obtained from stored polished rice or(More)
Rats fed on a supplement of raw cabbage, brinjal, dhal or powdered milk given in addition to a staple rice or laboratory stock diet show a high degree of protection against experimental ulceration following pyloric ligation. Wheat bran and ragi (a millet) conferred some protection, whereas rice bran and maize conferred no protection. The protection(More)
Aneurysms involving the venous system are a rare entity. We report the case of a 37-year-old woman who presented to us with activity-limiting left gluteal pain and who on consequent workup was found to have a left external iliac vein aneurysm in a setting of iliocavomegaly. She underwent successful treatment of her aneurysm with a novel approach that(More)
BACKGROUND The prevalence of duodenal ulcer is less in the northern wheat-eating regions of India and China than in the southern rice-eating areas. METHODS AND RESULTS Experiments were conducted on rat peptic ulcer models in which controls were fed on either known ulcerogenic rice or rice plus tapioca diets or on non-ulcerogenic stock diet. By using an(More)
BACKGROUND Ultrasonographic (US) assessment of abdominal aortic aneurysms is typically performed by measuring maximal aneurysm diameter from two-dimensional images. These measurements are prone to inaccuracies owing to image planes and interobserver variability. The purpose of this study was to compare the variability in diameter, cross-sectional area(More)
Intraductal papillary mucinous neoplasm (IPMN) is a mucin-producing epithelial neoplasm that carries a risk of progression to invasive pancreatic ductal adenocarcinoma. Lynch syndrome is an autosomal dominant condition caused by germline mutations in mismatch repair genes such as MSH2 that lead to microsatellite instability and increased risk of tumor(More)
We have performed two Phase I trials of the combination of dipyridamole, 5-fluorouracil (5-FU), and folinic acid in patients with advanced refractory malignancy, based upon in vitro evidence that dipyridamole can modulate the cytotoxicity of 5-FU. In the first trial, patients were treated every 4 wk with dipyridamole (50 mg/m2) p.o. every 6 h on Days 0 to(More)
Meciadanol, (O-methyl-3(+)-catechin), a histidine decarboxylase inhibitor was shown to have a marked protective action against experimental peptic ulceration in three rat models. The three methods used to induce ulceration were the instillation of absolute alcohol, pyloric ligation following an ulcerogenic South Indian diet and the instillation of rice bran(More)
Fresh rice oil protects against gastric ulceration in rats maintained on an impoverished diet, whereas stored oil is ulcerogenic. Rice oil contains ketoaldehydes which are ulcerogenic but their activity is prevented by the presence of antioxidants such as alpha-tocopherol, which is lost on storage. Protection may also be restored by the addition of(More)
