1. An additional 32 biopsies from adults investigated for diarrhoea but with a normal jejunal mucosa on histology were selected as controls.

2. This may partly explain the lack of change in the appearance of the duodenal mucosa on serial biopsy in this condition.

3. The normal gastric mucosa can prevent bypass diffusion of potentially noxious substances from the gastric lumen.

4. We showed that luminol enhanced chemiluminescence from colonic mucosa biopsy specimens is increased in patients with ulcerative colitis.

5. For positive controls, sections containing rectal carcinoma and normal mucosa were employed and for negative controls the primary antibodies were excluded.

6. Meye etal reported that tight junctions in the canine gastric mucosa were significantly damaged by exposure to aspirin.

7. The reduced bile acid absorption is likely to reflect damage to the terminal ileal mucosa.

8. The gastric mucosa resists the corrosive effects of peptic hydrochloric acid secretion and noxious extrinsic agents.

9. Diets rich in polyunsaturated fatty acids enhance the phenomenon of adaptive cytoprotection and render the duodenal mucosa more resistant to acid.

10. Furthermore, cultured mononuclear cells isolated from inflammatory bowel disease mucosa spontaneously secrete large amounts of IgG.

11. This finding is consistent with other reports showing that restitution of the damaged mucosa takes place in barbiturate anaesthetised rats.

12. Likewise, the carcinogenic action of bile may be related to the duration of exposure of gastric mucosa to biliary carcinogens.

13. Ultrastructural changes in colonic mucosa consistent with increased absorption have been described in ulcerative colitis, in both affected and unaffected areas.

14. In contrast, antral tumours mainly arose from mucosa showing the changes of chronic active gastritis.

15. Morphological measurements and enzyme activities carried out on intestinal mucosa are another good method of assessing dietary nitrogen quality.

16. The small intestinal mucosa was studied by histology, morphometry, biochemistry, and electron microscopy.

17. The dye was reduced by epithelial cells, vascular endothelium, and infiltrating mononuclear cells of the mucosa.

18. Invitro studies have shown impairment of bile acid absorption in the ileal mucosa of patients with cystic fibrosis.

19. The level of platelet activating factor in the rat gastric mucosa was determined after the administration of endothelin-1 using a radioimmunoassay method.

20. Examination round to the caecum showed no abnormality and biopsy specimens showed normal colonic mucosa.

21. Chronic inflammation mucosas and cancer nearby mucosas showed positive reaction only in their basal and superbasal cells.

22. Objective Mucosas from human stomach, terminal ileum and colon were studied for epithelial HLA-DR expression.

23. P53 protein expression was studied with immunohistochemically in 15normal oral mucosas(Sentence dictionary), 45 precancerous lesions and 21 invasive squamous cell carcinomas.

24. The distribution of positive rate of MDM2 protien in tumor tissues and nearby mucosas and normal nasopharyngeal tissues were 19%, 5%, 4% respectively, there are significant difference.

25. Methods: The gastrin levels in the arterial and venous blood of the cancer area and its cancer tissues, paracancer mucosas, and normal mucosas by radioimmunoassay in 26 patients with gastric cancer .

26. Conclusion:Purariae isoflavone have effects on treating the atrophic nasal mucosas and recovering E 2 level in ovariectomized rats.

27. Methods: Expressions of P16 were examined by S-P immunohistochemical staining in 20 cases of normal gastric mucosas and 100 cases of gastric carcinoma.

28. CONCLUSION : This nasal insulin spray has no damage to the nasal mucosas of rats.

29. Objectives To study the effect of Helicobacter pylori( HP) on gastric epithelial apoptosis, and the relationship between apoptosis and nitric oxide(NO)levels in gastric mucosas .

30. Objective To detect the telomerase activity in normal oral mucosas.
