Development of supervoltage treatment machine may minimize skin reaction by skin-sparing effect, but skin damage is still one of “the dose limiting factor” in radiation therapy. In spite of these importance, systemic histopathologic studies of skin in similar conditions which used in clinical treatment has not been performed so far. 60 mice were irradiated with conventional fraction (200x5/wk) and whole abdominal field (2x3 cm, from symphysis pubis to xyphoid process). Used machine was 250 KV, 24 mA. orthovoltage x-ray machine. Histopathological changes of acute skin reaction at the level of total irradiation dose were analyzed and possible mechanism of later chronic changes were investigated. Obtained results are as follows 1. In 1,000 rad irradiated group, only mild epidermal edema is noted. 2. In 2,000 rad irradiated group, slightly decreased number and size of hair follicles and appendages, dermal edema and scanty infiltration of inflammatory cells are visible. 3. In 3,000 rad irradiated group, marked increased capillary congestion and prominent infiltration of inflammatory cells are observed. 4. In 4,000 rad irradiated group, vascular wall thickening with proliferation of endothelial cells are prominent. Dermal thinning and hyalinization are newly developed. 5. In 5,000 rad irradiated group, complete desquamation of epidermis is not seen, despite of acceleration of all above mentioned changes.

Authors carried out an investigation of the helminthic parasites of the wild birds in Korea. Most wild birds were collected from Kyoung Sang Do, Kyoung Kee Do and Seoul area from September 1970 to March 1973. A total of 70 wild birds, 19 species were examined, which comprised as follows; 10 Anas platyrhynchus, 10 Anas fulicata, 4 Anas poeciolorhyncha zonorhyncha, 8 Anser albifrone albifrone, 5 Anser cygonopsis cygnoid, 10 Aythya fuligula, 6 Gallicrex cinerea, 2 Porgana fusca, 2 Phisianum calichius korponri, 4 Sterptopilla orientalis, Podiceps cristatus, Larus crasirotatus, Malantta fusca, Garis artcus, Buetes buteo, Egretta alba, Starmus philpiens, Bombycilla granulus. Trematode parasites found from six species of the wild birds. Echinostomatidae has been found from intestine of the Anas platyrhynchus platyrhynchus, Anas poeciolorhyncha zonorhyncha, Anas fulcata. Notocatylus attenuatis found from intestine of the Podiceps cristatus, Anas fulcata. Catylurus japonicus was found from rectum of the Anas platyrhynchus platyrhynchus, Anas poeciolorhyncha zonorhyncha.

A case of extrapulmonary silicosis involving abdominal lymph nodes in a 62-year-old man is presented. The patient underwent subtotal gastrectomy and regional lymph nodes dissection for gastric adenocarcinoma of clinical stage III. On gross examination, two separate gastric adenocarcinomas and multiple enlarged lymph nodes mimicking metastatic lesion were noted. Microscopic examination of the enlaged lymph nodes revealed characteristic sclerohyaline silicotic nodules without metastatic adenocarcinoma. Chest roentgenogram showed diffusely scattered multiple tiny nodular lesions in the entire lung fields, particularly the posterior side of both upper lung fields. He had worked in a mine for 18 years and had been exposed to silica for 5 of those years. We report incidentally found, unusual case of extrapulmonary silicosis.

PURPOSE: A new quantitative tumor marker, based on the combined measurement of urinary fragments of cytokeratins 8 and 18, namely the urinary bladder cancer antigen(UBC(TM)) test, has been proposed for the detection of bladder transitional cell carcinoma(TCC). We evaluated the diagnostic efficacy of UBC(TM) test in comparison with that of urinary cytology to establish UBC(TM) test for the diagnosis of TCC. MATERIALS AND METHODS: One-hundred ninety-six patients with hematuria were included in this study. Forty patients were diagnosed histologically as TCC by transurethral resection or radical cystectomy(group A), while the others had various benign urinary tract conditions(group B). RESULTS: UBC(TM) levels were significantly different between groups A (1851.39+/-4627microgram/l) and B (19.28+/-107.03microgram/l) (p<0.001). Sensitivity for diagnosis of TCC was 89.7%(36/40) in UBC(TM) test and 45%(18/40) in cytology(p<0.05). Specificity for diagnosis of TCC was 84.6%(132/156) in UBC(TM) test and 100%(156/156) in cytology. UBC(TM) test was significantly more sensitive than cytology in stage Ta(85.7% vs. 0%, p<0.05), T1 tumors(89.4% vs. 31.5%, p<0.05), and in Grades 1(83.3% vs. 25%, p<0.05) and 2(90.4% vs. 52.3%, p<0.05) tumors. UBC(TM) test was more sensitive in higher Grade(83.3% in Grade 1, 90.4% in Grade 2 and 100% in Grade 3). CONCLUSIONS: In comparison with urinary cytology, UBC(TM) test could be a valuable marker for diagnosis of TCC in patients with early stage and low grade TCC. Therefore, UBC(TM) test in association with cytology may be useful as a screening test for TCC of the bladder.
