Expression of the pS2 protein in breast carcinoma is a useful guide to evaluate the prognosis and response to tamoxifen. The pS2 protein is an estrogen-regulated 60 amino acid protein which was originally discovered following the screening of cDNA libraries in MCF-7 breast carcinoma cells and is induced through estrogen-dependent transcription of the pS2 gene. The presence of the pS2 protein in breast cancer is considered as valuable as the receptor status, or even more so, in predicting the response to hormonal therapy. We have investigated the pS2 protein expression in 62 cases of primary breast cancer in order to know the relationship between the expression rate of the pS2 protein and hormonal receptor status using immunohistochemical procedures on formalin-fixed and paraffin-embedded tissues. Concomitantly, both the estrogen receptors (ER) and progesterone receptors (PR) were examined using the immunohistochemical technique. Positive staining for the pS2 was seen in forty-nine cases (79%) of the tumors. Forty three cases (88%) of the pS2 positive tumors were ER positive and forty one cases (84%) of the pS2 positive tumors were PR positive ; forty six cases (93%) of pS2 positive tumors were positive for ER and/or PR. The pS2 status correlated significantly with the ER (p<0.0001) and PR (p<0.001). The results reveal a close association between the pS2 protein and either or both the ER and PR status.

Sixty one cases of gastric adenocarcinoma were studied immunohistochemically for expression of HLA-DR and secretory component(SC) in order to analyze the relationship between expression of these in gastric cancer cells and the adjacent mucosa. Immunostaining was detected within the cytoplasm and on the cell memgrane. The rate of HLA-DR and SC expressions in cancer cells were 59.0% and 49.2%, respectively, and 52.5%/52.5% and 31.2%/50.8% the mucosa in adjacent/remote from the site of to cancer. The SC expression in the adjacent mucosa was lower than that of the remote mucosa(p=0.027). The HLA-DR expression in the cancer cells in the intestinal type of gastric adenocarcinoma(73.9%) was higher than that of the diffuse type(14.3%) and it was statistically significant(p=0.02). The presence of an increased amount of lymphoid infiltration in the gastric mucosa was closely related to the expression of HLA-DR and SC. Decreased or absent expression of SC at the transitional mucosal cells was possibly a result of exposure to genotoxic agents due to the lack of protective function of SC-IgA. From these results, one can postulate that the expression of HLA-DR and SC may play an important role in atleration in microenvironment with lymphoid infiltration.

The authors present a case of spontaneous discitis in a 1-year-old female who presented with fever and limping gait. The erythrocyte sediment rate was increased. The roentgenograms revealed normal appearnce, and radioactive bne scan showed increased uptake at the affected level. Discitis should be considered in any child with limping gait or leg pain, refusal to walk, or abdominal pain. Early recognition may avoid unnecessary diagnotic and treatment procedures.

The introduction of the strong clover-leafed nail combined with the principle of reaming out the medullary canal and the development of image intensifiers has been extended the indications of the in tramedullary nailing. In this report, an attempt was made to introduce the method and to verify the indications and advantage of retrograde intramedullary nailing of humeral shaft fractures, as compared with the conventionally accepted methods.

PURPOSE: To correlate histologic subtypes with MR signal intensity in meniagioma and to find etiologic factors responsible for the signal characteristics of T2WI. MATERIALS AND METHODS: We. reviewed MRIs and histopathologic studies in 35 cases of meningioma. MR signal intenisty was measured with respect to cerebral cortex(gray matter) as hypointense, isointense, or hyperintense. Pathologically, meningioma was classified into subtypes, acording to the new WHO classification of brain tumors. The degree of cellularity, collagen, and vascularity was graded from 1 to 3, and presence or absence of psammoma bodies, microcysts, micronecrosis and microhemorrhage was obeserved. Multiple linear regression analysis was done to find relationship between the pathologic findings and MR signal intensity of T2WI. RESULTS: Even in the same subtype, cellularity, collagen and vascularty of the tumor were different. T1WI was not useful in discriminating pathologic subtype because most tumors were isointense or hypointense to the cortex regardless of histologic type. Most tumors showed various signal intensity on T2WI, but T2WI were not useful, either. Exceptionally, all five cases of microcystic meningiomas were hyperintense on T2W1. In analysing the relationship between MR signal intensity and pathologic factor, increased collagen content produced decreased signal intensity(P<0.01) and the existence of microcyst resulted in high signal intensity(P<0.01). Cellularity, vascularity, microcalcification, micronecrosis and microhemorrhage had no relationship with signal intensity on T2WI. CONCLUSION: Except for the five microcystic meningiomas with hyperintenty on T2WI there was no relationship between MR signal intensity and subtype of meningiomas. Pathologic factors influencing T2 signal intensity were microcyst and collagen. Even in the same subtypes of meningiomas, the T2 signal intensity was different. This may be due to different ratio of microcyst and collagen.

Nickel is widely known throughout the world as a common source of contact dermatitis. Korea is one of the rapidly developing countries where the use of nickel and nickel by-products is on the rise. Lacking in ore, Korea imports most of its nickel. In the last ten years, in relation to rapid industrial development, the amount of nickel imported has increased over 1, 000 times. Nickel dermatitis is becoming an increasing problem in the patch test clinic. With regards to this, we have tried the dimethylglyoxime spot test to all materials mentioned in the textbooks which are regarded as nickel sources in other industrialized societies, so as to make an up-to-date list of nickel sources applicable to Korea. In addition, we have also included traditional nickel sources such as acupuncture needles, fire pot, old and new coins and chest of drawers etc. We also have analyzed data concerning nickel imports to Korea during the past 10 years.
