AIM: To evaluate the eff icacy of colonoscopy follow-up after short-term anti-tuberculosis treatment in patients with nonspecific ulcers on ileocecal areas being suspicious of tuberculous colitis. METHODS: We prospectively analyzed the colonoscopic fi ndings before and after short term anti- tuberculosis treatment in 18 patients with nonspecifi c ulcers on the ileocecal area and compared them with 7 patients of confi rmed tuberculous colitis by acid-fast bacilli or caseating granuloma on colonic biopsy. RESULTS: Mean duration for short-term follow- up was 107.3 d with combined chemotherapy containing isoniazid, rifampicin, ethambutol and pyrazinamide. Seven patients with tuberculous colitis showed complete healing of active ulcers after short- term medication. After short-term anti-tuberculosis treatment, follow-up colonoscopy findings devided 18 patients with nonspecific ulcers into two groups by ulcer state. One is the "suspicious tuberculous colitis group" showing healing of ulcers and erosions and another is the "suspicious inflammatory bowel disease group" showing active ulcers with or without aggravation of the lesion. Finally, all 9 of the "suspicious tuberculous colitis group" were diagnosed as tuberculous colitis showing no recurrence of ulcers after termination of 9 mo of anti-tuberculosis medication. Patients of the "suspicious inflammatorybowel disease group" were f inally diagnosed as Crohn's disease or nonspecifi c colonic ulcers during long-term follow up. CONCLUSION: Follow-up colonoscopy shows a healing stage ulcer or scarring change without an active ulcer with just 2 mo to 3 mo of medication in patients with tuberculous colitis. Colonoscopy follow-up after short term anti-tuberculosis trial in patients with nonspecif ic ulcers on the ileocecal area is valuable in making early differential diagnosis of tuberculous colitis.

AIM: To evaluate the efficacy of radiotherapy (RT) in patients with advanced unresectable hepatocellular carcinoma (HCC). METHODS: A total of 65 patients were treated with RT in the Korea University Medical Center. The median age of the patients was 60 years, and 86.2% were men. 18.5% and 81.5% of the patients were diagnosed as TNM stage Ⅲ and Ⅳ-A, respectively. Treatment response was assessed 4 mo after initiation of RT. Tumor regression rate 1 mo after initiation of RT (TRR1m) was also assessed. Duration of survival was calculated from the initiation of RT. RESULTS: The objective treatment response was 56.9%. The 12 mo survival rate was 34.7%. Predictive factors for survival were Child-Pugh grade, α-fetoprotein level and treatment response. An objective response was achieved more frequently in patients with TRR1m ≥ 20% than in those with TRR1m < 20% (P < 0.001). CONCLUSION: RT is effective in treating advanced HCC with a tumor response rate of 56.9%.

AIM： To evaluate the association of glutathione S-trans-ferase mu （GSTM1） and glutathione S-transferase theta （GSTT1） null genotypes with the risk of gastric cancer （GC） and colorectal cancer （CRC） in a South Korean population. METHODS： We conducted a population-based, large- scale case-control study including 2213 GCs, 1829 CRCs, and 1699 controls. Null and non-null genotypes of GSTM1 and GSI-F1 were determined using realtime PCR. RESULTS： The null genotypes of GSTM1 and GSTT1 were not significantly associated with elevated risk of gastric （OR = 1.070, 95% CI = 0.935-1.224; OR = 1.101, 95% CI = 0.963-1.259, respectively） or colorectal cancer （OR = 1.065, 95% CI = 0.923-1.228; OR = 1.041, 95% CI = 0.903-1.200, respectively）. The frequency of the combined null GST genotype was not different between the two cancer groups and controls. Moreover, smoking, drinking, and age did not modify the association between these genotypes and the risk of gastric or colorectal cancer. CONCLUSION： GSTM1 and GSCI-1 null genotypes were not associated with increased risk of GC or CRC in Koreans.

Background Hypertension （HTN） is a major determinant of various cardiovascular events. Plasma levels of plasminogen activator inhibitor 1 （PAl-l） modulate this risk. A deletion/insertion polymorphism within the PAl-1 loci （4G/4G, 4G/5G, 5G/5G） affects the expression of this gene. The present study investigated the association between PAl-1 loci polymorphisms and HTN in Korean women. Methods Korean women （n=1312） were enrolled in this study to evaluate the association between PAl-1 4G/5G gene polymorphisms and HTN as well as other metabolic risk factors. PAl-1 loci polymorphisms were investigated using polymerase chain reaction amplification and single-strand conformation polymorphism analysis. Results The three genotype groups differed with respect to systolic blood pressure （P=0.043）, and diastolic blood pressure （P=0.009） but not with respect to age, body mass index, total cholesterol, low or high density lipoprotein cholesterol, triglycerides, or fasting blood glucose. Carriers of the PAl-1 4G allele had more hypertension significantly （PAl-1 4G/5G vs. PAl-1 5G/5G, P=0.032; PAl-1 4G/4G vs. PAl-1 5G/5G, P=0.034）. When stratified according to PAl-1 4G/5G polymorphism, there was no significant difference in all metabolic parameters among PAl-1 genotype groups in patients with HTN as well as subjects with normal blood pressure. The estimated odds ratio of the 4G/4G genotype and 4G/5G for HTN was 1.7 （P=0.005）, and 1.6 （P=0.015）, respectively. Conclusion These findings might indicate that PAl-1 loci polymorphisms independently contribute to HTN and that gene-environmental interaction may be not associated in Korean women.
