In femorsl neck fracture, viability of the femoral head depends on the revascularization of the femoral head. The purpose of this study is to observe the effect of early fixation and anatomical reduction by measuring the Tc-99m-MDP uptake ratio of the femoral head in experimental animsls. Femoral neck region of 20 mature rabbits were osteotomized completely and divided into 2 groups ; each group consisted of 10 rsbbits. Group 1 had two Kirschner wire fixation after osteotomy and anatomic reduction. Group 2 had no fixation after osteotomy. The uptake ratio of Tc-99m-MDP of the femoral head in each group were measured st the intervals of 24 hours, 48 hours, 1 week, 2 weeks, 3 weeks, and 4 weeks, respectively. The results obtained were as follows ; 1. In experimental group 1, the mean uptake ratio of the femoral head was 0.72±0.13 at 1 day after operation, increased to a level of 1.44±0.14 at 1 week, increased to a maximal value of 2. 90±0.36 at 3 weeks and decreased to a level of 1.10+0.12 at 4 weeks. 2. In experimental group 2, the mean uptake ratio of the femoral head was 0.70±0.10 at 1 day, 0.64±0.13 at 1 week, decreased to a maximal value of 0.33±0.05 at 3 weeks and 0.47±0.05 at 4 weeks, showing decreased level below 1.0. The results suggest that early anatomicsl reduction and rigid fixation of femoral neck fracture is helpful for revascularization of the femoral head and prevention of non union.

Fine needle aspiration of the breast is an important diagnostic tool in malignant lesions, but is also useful in differentiation of inflammatory breast diseases mimicking carcinoma clinically and radiologically. Recently, the authors have experienced eight biopsy-proven cases of chronic inflammatory diseases of the breast, which consisted of 4 cases of duct ectasia, 2 cases of fat necrosis, and a case of tuberculous mastitis and granulomatous mastitis respectively, Their cytoiogic features mainly based on the components and the relative frequency of inflammatory cells were evaluated for differential diagnosis of chronic inflammatory breast diseases. The results are as follows ; 1. In cases of duct ectasia, varying amount of neutrophils, mononuclear leukocytes, histiocytes and multinucleated giant cells were intermixed with benign epithelial cell clusters. 2, Abundant fat tissue fragments were diagnostic for fat necrosis. Histiocytes and mononuclear cells were main components but not rich, and neutrophils and giant cells were infrequently observed. 3. Characteristic granulomas composed of epithelioid cells, mononuclear leukocytes and Langhans' type giant cells and lymphocytic infiltrates were conspicuous in tuberculous mastitis, and occasionally neutrophils, necrotic materials and epithelial cell clusters were found. 4. In granulomatous mastitis, epithelioid cell granulomas were also noted but numerous neutrophils and histiocytes were intermingled within or outside the granulomas.

In a six-year period(1988. 5-1994. 4), fine needle aspiration cytology(FNAC) of 322 pulmonary lesions from 296 patients were performed at Soonchunhyang University Hospital. Of these 322, malignancy was diagnosed cytologically in 139(43.2%), suspicious malignancy in 7(2.2%), negative in 164(50.8%), and insufficient material in 12(3.8%). Malignant lesions consisted of 54 cases of adenocarcinoma, 50 cases of squamous cell carcinoma, 18 cases of small cell carcinoma. They were verified by histologic examination in 70 cases. There were 2(0.6%) false positive cases due to florid bronchoalveolar hyperplasia and atypical bronchial epithelial cells associated with granulomatous lesion. The overall accuracy rate was 90%, the sensitivity 84.3% and the specificity 94.7%.

Background:
Erythropoietin (EPO), which is associated with anemia, exerts neuroprotective effects in ischemic stroke. In cases of stenosis or narrowing of the main cerebral blood vessel, the prognosis is favorable if collateral blood circulation is well developed in acute stroke. Several studies have investigated the relationship between EPO administration and stroke outcomes. The present study investigated the correlation between serum EPO level and cerebral collateral circulation, which could result in favorable clinical outcomes.
Methods:
The study subjects were patients diagnosed with acute ischemic stroke who underwent initial brain magnetic resonance imaging between January 2020 and March 2022. Following brain computed tomography perfusion for collateral flow, serum EPO levels were measured. Collaterals were assessed according to the Mass system and divided into good collateral (GC) or poor collateral (PC) groups. Serum EPO levels were determined using a chemiluminescence immunoassay method. A correlation coefficient analysis was conducted to determine the correlation between serum EPO levels and GC. A receiver operating characteristic curve analysis determined the cutoff value of EPO for GC.
Results:
Serum EPO levels were significantly higher in the GC than that in the PC group (P<0.05). The cut-off level of serum EPO for a good outcome was 9.1 mIU/mL.
Conclusion
A high serum EPO (>9.1 mIU/mL) could be a marker of GC in patients with acute ischemic stroke that predicts good clinical outcomes.

Hypereosinophilic syndrome represents a heterogenous group filisorders with the common features of idiopathic prolonged eosinophilia of undetectable cause and orgar, system dysfunction. We experienced a case af hypereosinophilic syndrome in a 58 year old man who has been suffered from fever, chilling, generelized exfoliative dermatitis, periorbital sngioedema and oral ulcer for 3 weeks duration. The blood eosinophil count was 7436/mm and skin, liver, bone marrow biopsy revealed marked infiltration of eosinophils. We treated him with co ticosteroid, but 5 months later, he died due to hepatoencephalopathy, hepatorenal syndrome, dissernimted intravascular coagulopathy and acute respiratory distress syndrome.

Eosinophilia-myalgia syndrome(EMS) is a systemic illness that occurred as an epidemic by ingestion of over-the counter L-tryptophan preparation in the United States in October 1989. We report a Korean case of EMS not associated with the ingestion of either L-tryptophan or other nutritional supplements such as lysine and niacin.
