In this study, immunohistochemistry was used to examine the changes in the density of colonic endocrine cells - argyrophil and argentaffin cells, chromogranin A (CGA), serotonin, somatostatin and glucagon-containing cells in trinitrobenzene sulfonic acid (TNBS)-induced rat colitis. Ulcerative colitis was induced by the instillation of 10 mg of TNBS into the colonic lumen through the anus. To confirm the inducement of ulcerative colitis, the macroscopic and microscopic scores as well as the colonic myeloperoxidase (MPO) activities were monitored for 8 days after TNBS instillation in the colonic lumens. In addition, the number of argyrophil and argentaffin cells, CGA, serotonin, somatostatin and glucagon-immunoreactive cells were counted in the colonic mucosa, respectively. After TNBS instillation into the lumen of the colon from the anus in rats, increases in macroscopic and microscopic scores in the colon tissues were observed along with increases in the colonic MPO activities. Therefore, ulcerative colitis was relatively well induced by the TNBS instillations. Marked decreases in the number of colonic endocrine cells were detected in the TNBS-treated animal compared to the sham control. These results suggest that colonic endocrine cells were also disrupted by TNBS-induced ulcerative colitis.

PURPOSE: We wanted to analyse the differences of the radiological and clinical results between the combined approach and the posterior approach for treating posttraumatic kyphosis in elderly patients and to determine the risk factors for the loss of correction after the operation. MATERIALS AND METHODS: Between September 2004 and August 2009, 19 patients who underwent an operation for posttraumatic kyphosis and were follow-up for at least one year were included in this study. The combined approach (A group) was done for 10 patients, while the posterior approach (B group) was done for 9 patients. Radiological study and clinical evaluation, including the Korean version of the Oswestry disability index and the visual analog scale (VAS), were performed before surgery, after surgery and at the final follow-up. The risk factors related to the loss of correction of kyphosis at the fracture site were analyzed. RESULTS: In group A, the mean kyphotic angles were 35.2 before surgery, 11.1 degrees after surgery and 15.7 degrees at the final follow-up. There was 24.1 degrees (correction; 68.5%) of correction of the kyphotic angle with 4.6 degrees (19%) loss of correction. In group B, the mean kyphotic angles were 34.2 before surgery, 9.3 degrees after surgery and 13.8 degrees at the final follow-up. There was 24.9 degrees (72.8%) correction of the kyphotic angle with 4.5 degrees (18.3%) loss of correction. The clinical data was improved to the same degrees. The loss of correction was statistically correlated with osteoporosis. CONCLUSION: In conclusion, the posterior approach can correct the posttraumatic kyphosis in a fashion similar to that of the combined approach. The patient's osteoporosis should be thoroughly treated for preventing correction loss.

OBJECTIVE: The purpose of this study was to examine smoking status and the relates factors in the rural elderly. METHODS: This study was conducted with 2,421 elderly people(male 1,273 and female 1,148) residing in the selected 25 villages, and face-to-face interviews with the subjects were made from January 1 through March 30, 2002. RESULTS: The average age of the male subjects was 72.7 and that of the female subjects 72.8. The investigation of smoking states showed that for male subjects, smokers accounted for 49.4%, nonsmokers 26.9%, and abstainers from smoking 23.7% and that for female subjects, smokers accounted for 18.3%, nonsmokers 75.4%, and abstainers from smoking 6.3%. The level of 'low ADL' was significantly higher in abstainers. In men, smoking rate had higher in alone, non-job, queerstreet, 'high ADL'. In women, smoking rate had higher in younger age, queerstreet, unhealthy, 'high ADL'. CONCLUSIONS: The smoking rate of the elderly was relatively high, especially at abstainers. The smoking status of elderly was correlated with age, family type, job, economic status by self-assessment, Self-recognition of health status, ADL level.
