Objective: To investigate the expression of cyclooxygenase (Cox)-2 in carcinoma of the gastric cardia, and to evaluate the relationship between Cox-2 expression and angiogenesis. Methods: Forty-six resected tumor specimens from patients with carcinoma of the gastric cardia were collected, and 21 corresponding paracancerous normal tissues were randomly selected as controls. Immunohistochemical staining was used for detecting the expression of Cox-2. Monoclonal antiboty against CD34 was used for labeling vascular endothelial cells, and microvascular density (MVD) was determined by counting CD34-positive vascular endothelial cells. The correlations of Cox-2 expression and MVD with clinicopathological parameters of the patients were analyzed. Results: The positive expression rate of Cox-2 and MVD value in the cancerous tissue were 80.4% and 31.95 ± 3.87, respectively, which were significantly higher than those in the pericancerous normal tissues (14.3%, 16.28 ± 1.55; P <0.01). The positive expression level of Cox-2 and MVD value were associated with clinical TNM staging and lymph node metastasis. The Spearman rank correlation test showed that tumor MVD were closely associated with Cox-2 expression. Conclusion: Abnormal expression of Cox-2 and angiogenesis play important roles in tumor invasion and lymph node metastasis of carcinoma of the gastric cardia.

BACKGROUND: The erythemal response of the skin to UVB radiation is used as a diagnostic phototest and guideline to phototherapy. OBJECTIVE: The purpose of this study was to compare the UVB-induced MEDs to the back, arm, and thigh skin METHODS: A sunlight fluorescenct lamp(Waldmann UV 7001K) was used as a UVB radiation source. The back, arm, and thigh skin were irradiated with the dose, from 40mJ/cm2 to 180mJ/cm2. The minimal doses for erythema responses to the skin were assessed visually at 24 hours after irradiation. RESULTS: MEDs of the back, arm and thigh skin were 92.6 +/- 17.3mJ/cm2(mean +/- S.D.), 123.0 +/- 24.2mJ/cm2, and 126.6+/- 28.3mJ/cm2, respectively. The most frequent MED was 100mJ/cm2 for the back skin and 120mJ/cm' for the arm skin and thigh skin. CONCLUSION: In this study, UVB-induced MEDs to the back, arm, and thigh skin in young adult Koreans were assessed. A significant difference in the MED was found between the back and extremities skin, with a lower value for the back skin(92.6 +/- 17.3mJ/cm2) than for the arm skin(123.0 +/- 24.2mJ/cm2) or for the thigh skin(126.6 +/- 28.3mJ/cm2).

This is a case report of idiopathic intestinal lymphangiectasia occurring in a 3-year-old boy. Idiopathic intestinal lymphangiectasia is believed to be a part of the generalized congenital disorder of lymphatic system. The present case revealed markedly ectatic lymphatics in the lamina propria of duodenal villi with lymphorrhagia. Clinical features were typical of the protein-losing enteropathy; hypoalbuminemia, hypocalcemia, chylous ascites, edema of the lower extremities and mild lymphocytopenia. This case indicates that serious protein loss may ensue, even in cases of intestinal lymphangiectasia without abnormalities of extraintestinal lymphatics.

This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to prevent theileriosis were examined by PCR for Theileria sergenti infection from 2001 to 2002. In our study, the parasitemia range in T. sergenti-positive cattle by microscopy were from 0.1 to 3% (mean 0.8%). In terms of mean prevalence, 204 of the 301 Korean native cattle (67.8%) were positive reaction by PCR. Our results also revealed that the infection rate among cows (70.3%) was significantly higher than that among bulls (40.0%) (p < 0.01). T. sergenti infection among the over 3 year-old-group (75%) had a significant higher prevalence than that among the less than 3 year-old-group (61.8%) (p < 0.05). Our data also showed that grazing areas (76.1%) had the significant higher prevalence than non-grazing areas (51%) (p < 0.001). In conclusion, this study demonstrates that the prevalence of T. sergenti infection is high and that its prevalence in grazing cattle is higher than that in non-grazing cattle. Therefore, life-long treatment and the development of an optimal vaccine are needed to reduce the numbers of bovine theileriosis in both grazing and non-grazing areas.
