BACKGROUND : The recent studies shows that Helicobacter pylori (H. pylori) related chronic gastritis leads to dysplasia, intestinal metaplasia and gastric cancer. The aim of this study was to determine the association between precancerous lesion of stomach (dysplasia, intestinal metaplasia) and H.pylori infection in the elderly. METHODS : 469 patients were enrolled this study, Patients with intestinal metaplasia or dysplasia (case, n=148) were compared with controls (without intestinal metaplasia and dysplasia, n=321) about H. pylori positive rates H. pylori positivity was confirmed by histologic determination of endoscopic biopsy specimens. Results : 1) Among study populations H. pylori positive rates were 51.8% (55.8% in male, 40.7% in female). It was significantly higher in male (p=0.001). 2) There were no significant differences in sex distribution between cases and controls, but in old age, the cases were more frequent than in young age (p<0.001). 3) Age distribution of H. pylori positive rates were not significant between cases and controls. 47.5% in intestinal metaplasia, 43.4% in dysplasia, 21.3% in dysplasia+intestinal metaplasia were H. pylori positive. H. pylori positive rates were more higher in controls than cases, followed by in decreasing order by the intestinal metaplasia group, the dysplasia group, and those having both (p=0.003). 4) Age and sex adjusted H. pylori positive rates were more higher in controls (42.7%) than in cases (25.0%)(p<0.009). CONCLUSION : The prevalence of intestinal metaplasia and dysplasia was age dependent. But we couldn't explain the carcinogenic effect of H. pylori, because H. pylori positive rates were lower in cases than in controls

Bone formation by osteoblast may be closely related to the increase in intracellular Ca2+ activity of osteoblast. In order to study the effects of changes in Ca2+ activity of osteoblast-like cell on fracture healing, we changed intracellular Ca2+ activity of osteoblast-like cells by vanadate and verapamil. And the process of fracture healing was observed after injection of the treatment osteoblast-like cells into the fracture site by hematoxylin-eosin (H-E) stain and bromodeoxyuridine (BrdU) stain. The results were as follow: 1) The most effective range of concentration which could facilitate bone formation was 10-6 to 10-5 M. 2) H-E stain showed more abundant osteoblast and osteoid tissues, more active mitotic division of osteoblast, and earlier appearance of chondroblast and chondroid tissue, making the maturation of woven bone faster in the vanadate-treated group than in the control group. The opposite was true in the verapamil-treated group compared with the control group. 3) BrdU labeling index showed more active osteoblastic proliferation in the vanadate-treated than in the control group. The opposite was observed in the verapamil-treated group compared with the control group. From these results, the fracture healing appears to be facilitated and decelerated by vanadate which apparently increase intracellular Ca2+ activity of osteoblast and verapamil which decreases it, repectively. Therefore the change of intracellular Ca2+ activity of osteoblast can be considered to be one of fracture healing mechanisms and expected to be applied for clinical purpose.

PURPOSE: To investigate the trend of refractive change in hyperopic patients according to increases in age. METHODS: Eighty-eight children who had hyperopia of more than +1.50 diopters (D) and could be followed up for at least 5 years were included in this study. We divided the patients into two groups according to the level of initial hyperopia and retrospectively analyzed hyperopic refractive changes over a 5-year period according to age at initial diagnosis, presence of esotropia, amblyopia, astigmatism and anisometropia. RESULTS: We gained the following formula about the aspect of hyperopic reduction in 88 patients over a period of 5 years: Diopter (D)=7.99-2.14 Ln (age). The presence of anisometropia and amblyopia did not affect hyperopic reduction. Hyperopic reduction amounts in the group with a hyperopic eye of more than +5D at initial diagnosis were greater than in the group with a hyperopic eye less than +5D, and greater in the group with an astigmatic eye of more than 1D. The presence of esotropia and the age at initial diagnosis did not affect hyperopic reduction. CONCLUSIONS: We show that emmetropization in hyperopic children occurs according to the following formula: Diopter (D)=7.99-2.14 Ln (age). Both the initial level of hyperopia and the concurrent presence of astigmatism affected hyperopic reduction. However, the presence of anisometropia, amblyopia, esotropia and the age at initial diagnosis did not significantly affect hyperopic reduction.
