Synthesis and Pharmacological Activities of Novel 3-(Isoxazol-3-yl)-quinazolin-4(3H)-one Derivatives
1999
Several new 3-(isoxazol-3-yl)-quinazolin-4(3H)-one derivatives were synthesized and tested for their analgesic and antiinflammatory activities, as well as for their acute toxicity and ulcerogenic effect. A few compounds were as active as phenylbutazone in the writhing and acetic acid peritonitis tests. They had a very low ulcerogenic effect.

Lymphoproliferative disorders in patients receiving thiopurines for inflammatory bowel disease: a prospective observational cohort study.
2009
International audience; BACKGROUND: Reports of an increased risk of lymphoproliferative disorders in patients receiving thiopurines for inflammatory bowel disease are controversial. We assessed this risk in a prospective observational cohort study. METHODS: 19,486 patients with inflammatory bowel disease, of whom 11,759 (60.3%) had Crohn's disease and 7727 (39.7%) had ulcerative colitis or unclassified inflammatory bowel disease, were enrolled in a nationwide French cohort by 680 gastroenterologists, who reported details of immunosuppressive therapy during the observation period, cases of cancer, and deaths. The risk of lymphoproliferative disorder was assessed according to thiopurine expos…
Effects of beta-adrenoceptor drug stimulation on various models of gastric ulcer in rats.
1982
Abstract 1. Experiments were designed to evaluate the effect of the pharmacological activation of beta-adrenoceptors on various models of gastric ulcer in the rat. 2. Pretreatment with the beta-adrenoceptor stimulant drugs, isoprenaline or salbutamol, significantly inhibited stress-induced gastric ulcers. This anti-ulcer effect was abolished by propranolol but not by atenolol, suggesting that beta 2-adrenoceptors mediate this response. 3. In the pylorus-ligation model, salbutamol inhibited lesion formation and reduced the intragastric content of hydrogen ions, histamine and pepsin although the latter was only affected with the higher dose of salbutamol. 4. Salbutamol also prevented the ulce…
An evaluation of the efficacy of a topical gel with Triester Glycerol Oxide (TGO) in the treatment of minor recurrent aphthous stomatitis in a Turkis…
2017
Background Triester glycerol oxide gel (Protefix® Queisser Pharma, Germany) is a new topical agent that has the property of adherence to the oral mucosa by forming a lipid film which protects against mechanical trauma and may help to reduce oral tissue moisture loss and inflammation. The aim of this clinical trial was to determine the efficacy of a topical TGO gel and to also compare it with triamcinolone acetonide pomade in the treatment of minor recurrent aphthous stomatitis. Material and Methods This study was a randomized, double-blind, placebo-controlled clinical trial and 180 patients with the complaint of minor aphthous ulcers were enrolled in this study. The sociodemographic data an…
The protective role ofOcimum basilicumL. (Basil) against aspirin-induced gastric ulcer in mice: Impact on oxidative stress, inflammation, motor defic…
2018
The gastroprotective effect of Ocimum basilicum L. (Basil) hexane extract (OBHE) in aspirin-induced gastric ulcers in mice and its ameliorative effect on behavioral alterations were determined. Pretreatment with OBHE (100 or 200 mg kg-1) or misoprostol (50 μg kg-1) alleviated the aspirin-induced oxidative stress by significantly decreasing (p < 0.001) gastric ulcer index scores (57, 76 and 79%), gastric TBARS (by 49, 51 and 52%), NO (21, 28 and 29%), H2O2 (24, 42 and 45%), and the serum pro-inflammatory mediator TNF-α (21, 53 and 53%) and IL-6 (29, 30 and 31%), as well as by markedly increasing gastric GSH (41, 61 and 70%), GSH-Px (21, 32 and 34%), GST (33, 63 and 70%), GR (90, 99 and 112%)…
Antiulcer activity of Cyperus alternifolius in relation to its UPLC-MS metabolite fingerprint: A mechanistic study
2019
Abstract Background Gastric ulcer is one of the main prevalent gastrointestinal multi-etiological disorders with many associated complications and adverse effects. Our aim was to develop safer antiulcer therapies based on methanol or ethyl acetate extracts of tubers and aerial parts from Cyperus alternifolius. Methods Gastric ulceration was experimentally generated by administration of single oral doses of indomethacin (30 mg/kg) to fasted rats. The animals received methanol or ethyl acetate extracts of C. alternifolius tuber and methanol or ethyl acetate extracts of aerial parts at two dose levels (50 or 100 mg/kg). Ranitidine (50 mg/kg) was used as standard anti-ulcer drug. After 4 h, the…
The endoscopic spectrum of segmental colitis associated with diverticulosis.
2010
Objective An endoscopic classification of ‘Segmental colitis associated with diverticulosis’ (SCAD) is lacking. Our aim was therefore to assess the endoscopic spectrum of SCAD, comparing it with the histological and clinical features. Method A prospective study was performed from January 2004 to October 2007. Diagnosis of SCAD was made on the basis of specific endoscopic and histological patterns. Results A total of 6230 consecutive colonoscopies were performed during the study period. SCAD was diagnosed in 92 (1.48%) patients, with four endoscopic patterns: pattern A, ‘crescentic fold disease’ (52.20%); pattern B, ‘Mild-to moderate ulcerative colitis-like’ pattern (30.40%); pattern C, ‘…
Subcutaneous emphysema, pneumomediastinum and pneumoperitoneum after diagnostic colonoscopy for ulcerative colitis: a rare but possible complication …
2010
Dear Editor: Colonoscopy is regarded as a safe procedure, but complications may occur. The most dreaded are perforation and massive bleeding of the colon. The incidence of perforation is low but, despite increased experience with the procedure, it remains unchanged over time and in a large population study ranges from 0.6 to 1 per 1.000 procedures, depending on the centre and the data source. Few studies have assessed risk factors for colonoscopy-related bleeding and perforation. Gatto et al. have reported that there was a significant trend in the incidence of perforation with increasing age, people aged 75 years or older having a fourfold risk as compared to those aged 65–69 years; same re…
Bone status assessed by quantitative ultrasound in children with inflammatory bowel disease: a comparison with DXA
2016
Background: To determine the bone status in children with inflammatory bowel diseases (IBD) using quantitative ultrasound (QUS) measurement at hand phalanges and compare the obtained results with dual-energy X-ray absorptiometry (DXA). Methods: Fifty-one children with IBD underwent DXA and QUS measurements at hand phalanges in the year 2013. The control group for the QUS consisted of 460 children. Reference data for DXA comes from Hologic Explorer. Results: QUS measurements did not differ significantly between IBD patients and healthy controls. There was no difference between UC and CD subjects. DXA measurements in patients with IBD were lower than in the healthy population. Tanner stage an…
