Sites of hemorrhage depicted by MSCT were as follows:duodenal hemorrhage(n=12),jejunal hemorrhage(n=8) and ileal hemorrhage(n=9),while the pathological nature of the hemorrhagic lesions identified by MSCT was vascular malformation for 3 cases,intestinal diverticulum for 3 cases,ulceration for 1 case,intestinal tumors for 6 cases,intestinal tumor complicated with intussusception for 2 cases,inflammatory process and injury for 6 cases as well as Crohn's disease for 2 cases.
The nucleus is various in shape round,oval or quite irregular. The detectable rate of focal dysplasia is 8.0% (7/88) in erosive gastritis,10.9% (ll/l0) in superficial gastritis,38.4% (43/112) in atrophic gastritis,and 18.9% (18/95) in chronic gastric ulcer.
Methods 99 H. pylori strains isolated from 17 chronic superficial gastritis, 21 chronic atrophic gastritis, 19 gastric ulcer, 23 duodenal ulcer and 19 gastric cancer were studied for the prevalence of cagA, cagE and cagT genes by polymerase chain reaction (PCR).
Methods 't - UBT for helicobacter pylori were performed in 983 gastrointestinal outpatients, including 676 cases with chronic gastritis, 189 duodenal ulcer, 34 gastric ulcer, and 84 with non -gastrointestinal disorders.
There were significant difference between the two groups values were P<0.05,P<0.05,P<0.01,P<0.05,P<0.05.The layers of benign gastric walls were revealed clearly and regularly,the second layer of inner gastric wall was<3mm,with which the sensitivity was 96.49% and the specificity was 96.51%.
Diclofenac (25 mg kg-1) and meloxicam (7.5 mg kg-1) produced 9.3 and 19.6 mm2 ulcer areas in stomachs of rats, respectively, when used alone, but when combined with nimesulide diclofenac and meloxicam did not cause any injury in rat stomachs.
While ranitidine at 100 mg kg-1 dose prevented diclofenac-induced ulcer formation, it reduced meloxicam-induced ulcer formation significantly.
Antiulcer Effects of the Tripeptide PGP and Its Possible Metabolites (PG, GP, Glycine, and Proline) in Different Models of Ulcer
PG reduced the ethanol- and indomethacin-induced lesions approximately twofold but was considerably less effective in stress-induced ulcer.
GP decreased the stress- and indometacin-induced ulcer but tended to stimulate the ethanol-induced lesions.
We propose to treat deep corneal burns by grafting a living stromal equivalent, since keratocyte death and stromal destruction are the main factors of ulceration and destruction of the eye.
The Pro-Gly-Pro glyproline increases a resistance of the gastric mucosa (GM) to ulcerogenic factors in various models of ulceration and exhibits therapeutic properties in acceleration of the healing of an acetate ulcer.
Statistically reliable antiulcer effects in all the ulceration models were found for only two peptides: PGP and GPGPGP.
The PGP tripeptide displays a wide spectrum of physiological activities and affects a number of mechanisms that cause the development of GM ulceration.
The damage of barrier in mucosa with erosion or ulceration, and the thickness of mucin were examined by scanned electron microscope (SEM).
About 30% of patients with gastritis, active duodenal or gastric ulcer had antibody levels as low as the seroconverted dyspeptic patients but with normal gastroduodenal mucosa.C.
Study on clinical effect and mechanism of Jianpi Qingre Huayu Recipe (健脾清热化瘀方) in treating patients with gastric ulcer
Effect of mexican tea herb and pilular adina herb on concrescence of gastric mucosa in experimental gastric ulcer rats
pylori-infected child, and current guidelines recommend eradication therapy for infected children with duodenal and gastric ulcer, gastric lymphoma, and atrophic gastritis with intestinal metaplasia.
Other "less traditional" therapies, including probiotics, heparins, and anti-gastric ulcer remedies, challenge our understanding of the pathogenesis of ulcerative colitis and may provide further insights into future therapies.
No significant changes of PHA,E-rosette formation and lumphocyte transformation were noted in patients with leukoplakia vulral,gastric ulcer and malignant tumor before after He-Ne laser treatment.Whereas an average rise of 224mg% of serum IgG after laser radiation was detected (P<0.005)in patients suffering fr nasopharyngeal carcinoma etc.
The author reported the preliminary results of double contrast examination of upper G-I tract in 280 cases. 309 studies were performed on 280 patients with 200mA x-ray equipment without high-speed screen. Various kinds of lesions had been demonstrated in 163 patients(58.2%). The gastric inner walls were connected in 88.67% and the minor areae gastricae were demonstrated in 57.92% of the cases. The double contrast study had the advantage to discover those disorders difficult to be diagnosed by the conventional...
The author reported the preliminary results of double contrast examination of upper G-I tract in 280 cases. 309 studies were performed on 280 patients with 200mA x-ray equipment without high-speed screen. Various kinds of lesions had been demonstrated in 163 patients(58.2%). The gastric inner walls were connected in 88.67% and the minor areae gastricae were demonstrated in 57.92% of the cases. The double contrast study had the advantage to discover those disorders difficult to be diagnosed by the conventional barium meal examination. The former may demonstrate healing ulcer, erosion of gastric mucosa, early gastric cancer and others. The rate of definite diagnosis by double contrast study had increased to 20-30% with routine barium examination.
