The evaluation of the proliferative potential of malignant neoplasm is of major interest for predicting their biological behavior. MIB-1, a monoclonal antibody against the Ki-67 antigen, is a marker of cell proliferation, which is widely applied to human cancers recently. To assess the growth potential of uterine endometrial carcinoma, we performed immunohistochemical staining of MIB-1 in 34 cases of endometrial adenocarcinoma (endometroid type) from the paraffin sections. We evaluated its correlation with p53 overexpression and known prognostic factors including FIGO grade, nuclear grade, myometrial invasion, and estrogen and progesterone receptors. As a result, the MIB-1 labelling index was significantly correlated with FIGO grade, nuclear grade and myometrial invasion (p<0.05) and there was no significant correlation between MIB-1, ER or PR status. The expression of p53 protein showed significant correlation with FIGO grade and nuclear grade (p<0.05) and there was no significant correlation among p53 protein, myometrial invasion, ER and PR status. The MIB-1 labelling index revealed striking difference between p53 positive and p53 negative group (p<0.05). We concluded that MIB-1 labelling index is associated with poor prognostic parameter in endometrial adenocarcinoma, and may be a useful marker for predicting tumor of high grade and deep myometrial invasion, if MIB-1 labelling index is more than 50% and is accompanied by p53 overexpression.

Sclerosing polycystic adenosis (SPA) of the salivary glands is a rare entity analogous to fibrocystic disease of the breast. Less than 50 cases of SPA have been published in the literature. We report the first Korean case of SPA of the right parotid gland. A 34-year-old man presented with a slowly growing right parotid mass. Computed tomography showed a relatively well-demarcated, heterogeneously enhancing mass with multiple small calcifications. Fine needle aspiration showed cohesive sheets of epithelial cells with granular oncocytic cytoplasm and scattered lymphocytes. The parotidectomy specimen showed a 3 cm-sized solid nodular lesion with small cysts. Microscopically, the lesion was an unencapsulated mass of sclerotic fibrous tissue with cystic ducts, multiple calcifications, and lymphoplasma cell infiltration. Sclerosing adenosis and cystic ducts with frequent apocrine-like cells were noted. Familiarity with the cytologic and histological features of SPA is very important making the correct diagnosis.

BACKGROUND: Autoimmune hemolytic anemias are characterized by autoantibodies recognizing antigens on the Individual's own red blood cells, resulting in immune- mediated hemolysis. Blood transfusions have been regarded as hazardous in patients with autoimmune hemolytic anemia (AIHA) because of potential intensification of hemolysis and a presumed high incidence of alloimmunization. METHODS: We examined the pretransfusion and posttransfusion hemoglobin levels in 6 patients with autoantibodies in their sera, which showed panagglutinations with all bloods tested in the compatibility testing. They received 'least' incompatible blood because of inability to find compatible blood. RESULTS: When we compared pretransfusion hemoglobin level with posttransfusion hemoglobin level, in 5 of 6 patients with AIHA, the hemoglobin levels were increased after red cell transfusion. 4 patient who did not respond to transfusion therapy initially had an increase in hemoglobin level after steroid treatment. Any signs or symptoms indicating hemolytic transfusion reaction were not observed ducting the transfusion period in all patients. CONCLUSIONS: The decision to transfuse in AIHA should consider multiple factors including the patient's clinical status, the potential benefit of transfusion, the potential response to other therapeutic modalities, but must never be regarded as contraindicated, even though the compatibility test may be strongly incompatible.

OBJECTIVE: We studied the expression of epidermal growh factor(EGF) and transforming growth factor(TGF)-a and epidermal growth factor receptor(EGFR) in human trophoblast and decidua at the first and third trimester. METHODS: To confirm the expression of EGF, TGF-a and EGFR immunohisochemically in human trophoblast and decidua, we used monoclonal antibodies to EGF, TGF-a and EGFR. RESULTS: Immunohistochemical stainings using anti-EGF, anti-TGF- a and anti-EGFR antibodies showed a specific stainings in human trophoblast and decidua at the first and third trimester. The staining intensity of EGF in the trophoblast was light to moderate at the first trimester and moderate at the third trimester, and that in the decidua was light to moderate at the first trimester and light at the third trimester. The patterns of expression of TGF- a in the trophoblast and decidua were similar to that seen with EGF in the trophoblast and that of EGFR in trophoblast and decidua were similar to that seen with EGF in decidua. CONCLUSION: These findings suggest that EGF, TGF-a and EGFR may play an important role in human trophoblast and decidua during gestation.

Acrodynia is caused by chronic mercury poisoning and/or mercury, hypersensitivity occuring in infants and children only. Ingestion or inhalation of mercury contained in some house paints, calomel ingestion, the use of mercury ointments and other mercurial preparations can be the causes of acrodynia. We herein report a 3-year-old boy with typical acrodynia after expoaure to house paints and lacquer for 2 months. His hands and feet were erythematous and edematous vesiculo-bullous lesion with acral dark bluish discoloration. Mercury levels of blood and urine were significantly incresed by 61. 2ug/dl and 264ug/L (normal; below 30ug/dl and 100ug/L).
