Renal dysplasia results from aberrant metanephric histogenesis caused fundamentally by a defect in inducer tissue or responding tissue. Dysplastic kidneys vary tremendously in gross and microscopic appearance but are characterized by abnormal organization and a mixed population of primitive structures, such as fetal or immature cartilage, dysplastic ducts, immature tubules, and undifferentiated mesenchyme. We report a case of unilateral multicystic renal dysplasia associated with an ipsilateral ectopic ureteral orifice entering a seminal vesicle cyst in a 33-year-old man. He was admitted due to primary infertility which had developed three years ago. The his semen analysis revealed oligospermia. No evidence of a family history of renal dysplasia was reported. Microscopic examination showed that the entire kidney was composed of cysts lined by flattened cells, dysplastic ducts and immature tubules surrounded by collars of spindle cells, primitive mesenchyme, and a few aberrantly formed glomeruli.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

BACKGROUND: Dietary intervention is important in the prevention and treatment of chronic degenerative diseases, such as diabetes mellitus, hyperlipidemia, obesity, fatty liver, cerebrovascular accident, hypertension. To contribute to the improvement of periodic health examination, we investigated the current status of nutritional screening. METHODS: We gathered information about nutritional screening and education by review of questionnaires and telephone interview with physicians and dieticians in 20 university hospitals. RESULTS: Nutritional screening and education was not being done in 11 out of 20 hospitals. It was done only to those who were need of in 3 hospitals. In one hospital, brief nutritional screening was carried out to all and nutritional education only to those who were in need of it. In the rest of the hospitals, nutritional screening and education was dane to all. CONCLUSIONS: Nutritional screening and education was sufficient for primary and secordary prevention in only a few hospitals. Joint development of nutritional screening tools and educational materials is needed.

Recent investigations have revealed that autocrine growth factors and their receptors are closely related and play an important role in controlling cancer cell growth. We performed an immunohistochemical study on the expression of epidermal growth factor (EGF), transforming growth factor-alpha (TGF-alpha), epidermal growth factor receptor (EGF-R), c-erbB-2, and PCNA labelling index in 60 cases of human gastric carcinomas. TGF-alpha was detected in 38 cases (63.3%), EGF in 26 cases (43.3%), EGF-R in 44 cases (73.3%), and c-erbB-2 in 18 cases (30%). These growth factors, EGF-R and c-erbB-2, were found more often in advanced gastric cancers. The PCNA labeling index was significantly higher in tumors with the expression of EGF-R or c-erbB-2. Tumors with simultaneous expression of EGF, TGF-alpha, EGF-R and c-erbB-2 was associated with a high PCNA labeling index. A correlation was observed between the synchronous expression of growth factors and its receptors and histological differentiation. The results suggest that the expression of EGF, TGF-alpha, EGF-R and c-erbB-2 are closely related and plays an important role in the growth and progression of human gastric carcinoma.

It remains a problem that successful revascularization and reperfusion after ischemia are associated with high systemic complication rates and severe local tissue injuries. With prolonged ischemia, there is damage to tissue from anoxia, but further injury may occur after reperfusion. The activation of leukocytes and endothelial cells during reperfusion causes neutrophil adhesion in capillaries, resulting in plugging and further ischemia, Alternativety, neutrophil adhesion to endothelium leads to the migration of neutrophil with local edema formation, hemorrhage and thrombosis. Some chemotactic and activating factors are needed to propel neutrophils to the site of local inflammation. The chief cytikines that induce a pro-adhesive state in endothelium are tumor necrosis factor-alpha(TNF-alpha), interleukin-1 beta(IL-1 beta) and endotoxin or lipopolysaccharide(LPS). Similarly, TNF-alpha,and to a lesser extent interleukin-8(IL-8), is the important stimulus that acts on neutrophils and other leukocytes to alter their adhesion. The purpose of this study was to evaluate the pathogenetic role of IL-8 after perfusion with CDl8 monoclonal antibody(CDl8 mAb), the blocking antibody of neutrophil adherence, on reperfusion injury in rat epigastric island skin flap. A 6 X 3 cm-sized island skin flap was made on the abdomen. The epigastric pedicle was occluded for six hours with ambient temperature. Fifteen minutes before reperfusion, the flap was perfused with saline and CDl8 mAb(1 mg/kg). For evaluation of IL-8 levels, tissue fluid and serum were obtained at 4, 8, 12 and 24 hours after reperfusion. IL-8 concentrations of the CDl8 mAb group in the tissue fluid were significantly decreased at 8, 12 and 24 hours compared to the control group(P > 0.01), but the difference between the two groups was not significant at 4 hours after reperfusion IL-8 concentrations of the CDl8 mAb group in the serum were significantly decreased over time compared to the control group(P > 0.05, p > 0.01). Form the above results, we concluded that blocking neutrophil adherence using CD18 mAb within the peak level of IL-8 at 4 hours after reperfusion may be a better method of reducing reperfusion injury to the island skin flap.
