PURPOSE: This study was carried out to investigate the correlation among tumor angiogenetic activity, epithelial membrane antigen (EMA) reactivity and various clinicopathologic parameters. We also evaluated the validity of both as an independent prognostic factor in patients with papillary thyroid carcinoma. MATERIALS & METHODS: We studied 120 patients out of 727 patients with papillary thyroid casrcinoma who underwent thyroidectomy at our institute from January 1986 to December 1994. The age of the patients ranged from 14 to 80 years with a mean of 48.2 years. There were 24 males and 96 females (M:F=1:4). The paraffin embedded tissues of these patients were stained with the monoclonal antibodies against factor VIII related antigen, antigen CD34 to highlight microvessels and against EMA to show immunoreactivity. We measured microvessel density (MVD) in the area of highest vascular density at 200 times of magnification (0.785 mm2 per field). The positive cells for EMA were counted as percentages of the whole cell population and the degree of reaction was rated on a five-point scale. RESULTS: Mean MVDs and EMA reactivities by location of tissue per field were 64.8+/-18.9, 1.97+/-0.74, in the center of the tumor; 41.3+/-15.3, 1.55+/-0.68 in the periphery of tumor; and 22.1+/-14.4, 1.09+/-0.75 in normal thyroid tissue, respectively. In relation to TNM stage, only the MVDs of patients with stage IV disease were higher than those of other disease stages with statistical significance (p<.05). In relation to DeGroot stage, the MVDs of patients with stage IV disease was also higher than others with statistical significance (p<.005). There were no significant differences in MVD and EMA reactivity between the two groups of low risk (n=77) and high risk (n=43) by AMES scale. The MVDs and EMA reactivities of patients with local recurrence (n=23) and death (n=7) during the follow-up period had no statistical significance against those patients without recurrence and living patients. CONCLUSION: Tumor angiogenic activity and EMA reactivity in papillary thyroid carcinoma did not correlate with TNM stage, DeGroot stage, AMES score, local recurrence, and patient death. However, MVD was significantly higher in patients with distant metastasis and may be useful in predicting the distant metastasis in papillary thyroid carcinoma.

We presented several cases of the exophthalmos due to the orbital tumors, with the review of the literatures. We performed modified Kronlein operation and anterior orbitotomy, appropriately for each cases to improve the visual acuity and at least to correct cosmetically the proptosed eye. It will be better to do one's best in order to search a possible way to save the eye ball by which the ophthalmologist can remove the orbital tumor even if the patient lost his vision.

Carcinoma of Gall bladder remains a terminal illness in most patients despite improved diagnostic capabilities, better perioperative care and a more aggresive surgical approch based on improved knowledge of this tumors natural histiory. Overall 5-year survival rates remain below 5%. This failure to significantly improve patient oucome is largely due to late recognition of gall badder cancer. Authors experienced 21 cases of gall bladder cancer confirmed by operation at the Kwang Ju Christian hospital from march 1983 to March 1991, and the results obtained were summarized as follows.

PURPOSE: The aim of this study was to assess the feasibility and safety of laparoscopic multivisceral resection of colorectal cancer adherent to adjacent organs. METHODS: We reviewed retrospectively 32 patients undergoing elective laparoscopic multivisceral resection for colorectal cancer adherent to adjacent organs between June 2003 and May 2009. Survival curves were generated by Kaplan-Meier method. RESULTS: The median age of 32 patients was 73 years. In 10 of 17 rectal cancer patients (59%), neoadjuvant chemoradiation was performed. All the surgeries were completed laparoscopically. The postoperative complications occurred in 21.9% and there was no operative mortality. The median length of hospital stay was 15.5 days. In 23 of 32 patients (72%), the resection was considered curative. Median follow-up period of all patients and curatively resected patients was 22 (range, 2~65) months, 34 (range, 4~65) months respectively. Local recurrence rate, the 3-year overall survival rate and the 3-year disease free survival rate of 23 curatively resected patients was 4.3%, 92.9% and 84.4%, respectively. CONCLUSION: Laparoscopic multivisceral resection is feasible and safe in highly selected patients with colorectal cancer adherent to adjacent organs. Further validation is needed.

Infection with Helicobacter pylori (H. pylori) is strongly associated with duodenal and gastric ulcers. Substantial epidemiological data has revealed that high rates of H. pylori infection might be related to high rates of gastric cancer and gastric adenocarcinoma. In this study, a medicinal herbal plant, Cinnamomum cassia, was examined and screened for anti-H. pylori activity. Seventy percent ethanol was used for herbal extraction. For anti-H. pylori activity screening, inhibitory zone tests as an in vitro assay and in vivo study using a Mongolian gerbil (Meriones unguiculatus) model were performed. Also, the safety of herbal compounds was evaluated by animal study. As a result of inhibitory zone test, Cinnamomum cassia extract demonstrated strong anti-H. pylori activities.

As results of the safety study, after 28 days treatment of the Cinnamomum cassia extract, the animals were not detected any grossly and histological changes. These results demonstrate that it can be successfully cured against H. pylori infection and protected from H. pylori-induced pathology with Cinnamomum cassia. It could be a promising native herb treatment for patients with gastric complaints including gastric ulcer caused by H. pylori.

PURPOSE: Measles is one of the most highly communicable infectious disease, but has become a rare disease with the widespread use of vaccine. Recently, however, resurgence of the disease in school aged or adolescents who had received the vaccine before or at the 15 month warrants reappraisal of the efficacy of the vaccination. The purpose of this study was to investigate positive prevalence of antibody and its quantitative titers in different age groups in order to determine necessity and appropriate time of booster vaccine. METHODS: We measured measles antibody in the sera of 192 children from different age groups(61 cases from 4-6 years of age, 40 cases from 8-9 years of age, 47 cases from 12-13 years of age, 44 cases from 15-16 years of age). Eight to ten children from each group were selected and quantitative antibody titers were measured by EIA(measles Ig G EIA SEIKEN) method. RESULTS: 1) The positive prevalence of measles antibody in four to six year age group(72%) was significantly lower than the expected positive prevalence of measles antibody(95%) (p<0.001). 2) Median antibody titer in twelve to thirteen year age group tended to be relatively lower than the other age groups. 3) There was no significant differences in the positive prevalence of measles antibody and median titers between sex. CONCLUSIONS: This data supported that the booster vaccination be needed at four to six years of age.

We experienced 3 cases of Candida esophagitis in infancy which were diagnosed by esophageal endoscopy. First case, 10 month-old boy with combined immune deficiency had suffered from oral thrush and poor feeding for more than 4 months. Esophageal endoscopy revealed multiple whitish creamy patches on the friable erythematous and necrotic mucosa of the esophagus. He was firstly treated with amphotericin-B but in vain. Then he was treated with fluconazole (5 mg/kg/day) and in a few days oral thrush nearly disappeared and endoscopy after 2 weeks revealed complete healing of the esophagitis. Second case, 6 month-old boy with some cellular immue defect also suffered from oral thrush, poor feeding and intermittent fever. He was treated with fluconazole and oral thrush was imporved. He was discharged without follow up endoscopy. Third case, 4 month-old girl with liver cirrhosis due to infantile cholestasis had Candida sepsis. Esophagitis was found incidentally during the endoscopic examination of esophageal varix. First 2 cases showed multiple small filling defects and decreased motility on esophagography. Candida antigen was not detected in the sera of all 3 cases of candidiasis. We conclude that Candidia esophagitis should be suspected when an infant has been suffering from long-term treatmet-resistant oral thrush and poor feeding and that esophageal endoscopy can be easily performed in infants also and useful in diagnosing esophagitis and assessing the outcome of treatment.
